Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading apparatus for book originals such as copying machines and facsimiles.

[0002]

2. Description of the Related Art As an apparatus and method for reading a book document, (1) the document surface of a book document placed on a document support table with its face open is brought into contact with an information contact glass, and the contact glass is sandwiched. A device for exposing and scanning a document image by scanning of scanning optical systems arranged opposite to each other.
(2) There is known a device for reading an original image by exposing and scanning the original surface of a book original placed on the original placement surface with the book spread open.

On the other hand, as a document reading device in a copying machine, a facsimile, etc., a sheet document is automatically conveyed to a document reading position to read document information, and the document which has been read is automatically discharged from the document reading position. An automatic document feeder (ADF) is known.

As described above, when the original is a sheet original, the original information can be automatically read by mounting the ADF, but when the original is a book original, automatic page turning is performed. Since it is difficult to realize the mechanism, at present, the pages of the book manuscript can be turned only manually.

In view of the current situation, various proposals have been made for methods and means for automating the troublesome reading of book originals.

As an apparatus and method for automatically turning a page of a book original, which is indispensable for realizing the automatic reading of the book original, (3) a book original placed facing downward is moved while the original page is moved. Device for sucking and separating, (4) Device for sucking and separating manuscript pages of a book manuscript placed facing upward, (5)
2. Description of the Related Art There is known a device for flipping a document page of a book document placed by opening it upwards with a roller, an arm, or the like.

However, the above-mentioned conventional technique has many proposals only for ideas and has not reached the level at which it can be realized, and has the following problems.

That is, (1) the document surface of a book document placed on the document support table with the document opened upward is brought into contact with the contact glass for information, and the contact glass is sandwiched between the scanning optical systems to be opposed to each other. In an apparatus that exposes and scans a document image by means of a book document, it is necessary to move the book document from the position where the document page of the book document is turned to the position where exposure scanning is performed, and the document exposure scanning efficiency decreases and
There was a problem that it was difficult to avoid increasing the size of the device.

Further, (2) an apparatus for reading an original image by exposing and scanning the original surface of a book original placed on the original placement surface with the book spread upward is called an increase in size of the apparatus. Although the points can be solved, since there is no means for pressing the document surface of the book document, the surface of the placed document easily floats up, and the reading scanning of the document surface becomes unstable.

On the other hand, (3) in an apparatus for sucking and separating the original pages of a book original that are opened downward and placed on the book original, the reliability of page turning is impaired due to the effect of the weight of the book original. In addition, there is a risk that the document surface may be rubbed when the page is turned and the document may be damaged, and further, there is a problem in that the apparatus must be upsized due to its configuration.

Further, (4) a device for sucking and separating the document pages of the book document placed facing upwards and placed, and (5) a roller, an arm, etc. for the document pages of the book document placed facing upwards and placed. In the flipping device and the like, the conventional page separating mechanism that moves in the upper space of the book document is complicated and large, and thus there is a problem that it is difficult to avoid increasing the size of the device.

In view of the present situation, the applicant of the present invention has disclosed, for example, as disclosed in Japanese Patent Application No. 2-193589, one of the page pressing belts stretched along the document placing surface of the document table. While forming a bypass portion that is separated from the document placing surface in the section, the page storing means, with respect to the document surface of the book document that is opened and placed between the document placing surface and the page pressing belt, A book page page reading device (hereinafter, referred to as MFDS) for performing page turning of the book document and document scanning by relatively moving a page page reading unit provided with a page adsorbing unit, a page separating unit, a reading unit, and the like.
Called).

According to the proposed MFDS, as described in the above specification and the like, it is possible to completely automate the page turning operation and the document reading scanning of a book document, which requires a great deal of labor for copying work and the like. As a result, it is possible to realize a multi-function document reading system that remarkably improves productivity such as copying.

Next, the printer 3 shown in FIG. 9 and FIG.
00 will be described. A schematic cross-sectional view of this printer 300 is shown in FIG. The image information after the image processing is written on the photosensitive drum 170 in the form of a set of light spots by raster scanning of laser light in the writing unit of the printer 300.

A semiconductor laser is used as the laser light source at this time. FIG. 18 shows a plan view of the writing section of the printer 300. In FIG. 18, the laser light emitted from the semiconductor laser 171 is the collimating lens 17
It is changed into a parallel light flux by 2 and by the aperture 173,
It is shaped into a light beam with a fixed shape.

The shaped beam is incident on the polygon mirror 175 in a form compressed by the first cylinder lens 174 in the sub-scanning direction. The polygon mirror 175 has an accurate polygonal shape and is rotated by a polygon motor 176 in a fixed direction at a fixed speed.

The rotation speed of this polygon mirror 175 is
It is determined by the speed of the photosensitive drum 170, the writing density, and the number of surfaces. The reflected light of the laser light entering the polygon mirror 175 is deflected by the rotation of the mirror. This deflected laser light is transmitted to each fθ lens 177.
It is incident on a, 177b, and 177c.

These fθ lenses 177a, 177b,
177c is a photosensitive drum 17 for scanning light with a constant angular velocity.
It has a function of converting the scanning light at a constant speed on 0, a function of forming an image of the scanning light on the photoconductor drum 170 so as to form a minimum light spot, and a function of correcting the surface tilt.

Each fθ lens 177a, 177b, 177
The light that has passed through c is guided outside the image area by the synchronization detection mirror 178 to the synchronization detection sensor 179, and after the synchronization signal for outputting the cue signal in the main scanning direction is output, the image data becomes 1 Only the lines are output,
By repeating this, one image is formed. On the other hand, a photosensitive layer is coated on the surface of the photosensitive drum 170.

Here, the semiconductor laser 171 has a wavelength of 780 nm.
Organic photoconductors (OPC), α-Si, Se-Te, and the like are known as photoconductors having sensitivity to the wavelength, but in the present embodiment, organic photoconductors are used.

In general, in the case of laser writing, there are an N / P process of shining light on the image portion and a P / P process of shining light on the background portion. In this embodiment, the laser writing process is performed by the image writing. The N / P process that illuminates parts is adopted.

In FIG. 17, the surface of the photosensitive drum 170 is uniformly negatively charged by a charging charger 180 of the scorotron type in which the photosensitive drum 170 has a crocodile grid.

Next, the negatively charged photosensitive drum 1
When the image portion of 70 is irradiated with laser light and the potential of the image portion is reduced, the surface potential of the photoconductor drum 170 is −750 to −800 V and the image portion potential is −50.
An electrostatic latent image of about V is formed.

With this electrostatic latent image, a bias voltage of -500 to -600 V is applied to the developing roller of the developing device 181, and
The negatively charged toner makes the image visible. The image visualized by the developing device 181 is the photosensitive drum 1
It is transferred by the transfer action of the transfer charger 182 which applies a positive potential charge from the back surface side of the transfer paper to the paper surface of the transfer paper synchronized with the rotation of 70 and fed.

The transfer paper to which this image has been transferred is separated charger 183 held integrally with transfer charger 182.
AC removal of electricity by the photoconductor drum 17
Separated from the zero surface.

At this time, the toner remaining on the photoconductor drum 170 without being transferred to the transfer paper is scraped off from the surface of the photoconductor drum 170 by the cleaning blade 184 and disposed around the cleaning blade 184. It is collected in the stored tank 185. Further, the potential pattern remaining on the surface of the photoconductor drum 170 is erased by being irradiated with light by the static elimination lamp 186.

A photo sensor 187 is provided immediately downstream of the developing device 181. This photo sensor 187
Is composed of a light receiving element and a light emitting element, measures the reflection density of the surface of the photoconductor drum 170, and when this reflection density (toner density after development) becomes equal to or lower than a preset reference value. , And outputs a toner replenishment signal for replenishing the developing device 181 with new toner.

That is, for example, the photosensor 187 writes a fixed pattern (pure black or halftone dot pattern) in its optical writing portion at a position corresponding to the reading position of the photosensor 187, and develops this pattern. The density of the developed image is judged from the ratio of the light reflectance of the subsequent pattern portion and the light reflectance of the photosensitive drum 170 outside this pattern portion, and when the density of this image is lower than the reference value, It is configured to output a toner replenishment signal.

Here, in the case where the new supply toner is insufficient, the photosensor 187 takes advantage of the fact that the development density does not increase even if the toner supply signal is output.
May be used also as a sensor for detecting the shortage of the remaining amount of toner.

On the other hand, the printer 300 of the present embodiment is provided with a plurality of cassettes 188a and 188b, and is constructed so that the transfer paper on which the image has been transferred once can be fed on both sides through the refeed loop 189. ing.

The rollers are rotated and the transfer paper in the cassette is fed until it abuts on the nip of the registration roller 191.

The registration roller 191 starts rotating at a timing at which the position of the image formed on the photosensitive drum 170 and the position of the transfer paper are synchronized, and the registration roller 191 transfers the image toward the surface of the photosensitive drum 170. Feed the paper.

As a result, as described above, an image is transferred to the transfer paper, and after being separated from the surface of the photosensitive drum 170, the transfer paper is suctioned and conveyed to the separation and conveyance section 192, and the heat roller 193, and The toner transferred onto the paper surface is fixed by the fixing roller composed of the pressure roller 194.

On the transfer paper on which the toner is fixed, the switching claw 195 faces the position shown in FIG. 19A during normal printing, and the switching claw 195 causes the printer 3 to move.
The sheet is discharged onto the sheet discharge tray 169 through the sheet discharge port of 00.

Here, when the print mode of the printer 300 is the "double-sided mode", the switching claw 195 is set as shown in FIG.
The position is switched to the position shown in (b), and the transfer sheet is conveyed toward the double-sided conveyance path formed on the left side of the printer 300.

This transfer paper passes through the reverse guide claws 196 and is once guided to the reverse guide tray 197.
The reversing guide claw 196 is switched, and the reversing guide roller 198 is reversely rotated (reversed).
The sheet is fed until it abuts the nip 1.

The transfer sheet re-fed in this way is
In the same manner as the above-mentioned normal printing, the photosensitive drum 1
After the toner image formed on 70 is transferred and fixed,
The sheet is discharged onto the sheet discharge tray 169 via the switching claw 195, which is switched to the initial state shown in FIG.

If is set, the switching claw 195 is switched to the position shown in FIG. 19B as in the case of the “double-sided mode” described above, and the transfer sheet is temporarily discharged without being discharged as it is. It is transported toward the transport path.

Then, the rear end of the transfer paper is changed to the switching claw 19.
5 and immediately after that, the switching claw 195 is moved to the position shown in FIG.
While being switched to the position shown in (c), the rotation direction of the switchback roller 199 is reversed, and the transfer paper guided to this double-sided transport path is switchback transported,
The sheet is discharged onto the sheet discharge tray 169 through the sheet discharge port of the printer 300.

In the "rear surface discharge mode", the transfer paper printed on one side has the image fixing surface thereof on the discharge tray 169.
Since the sheet is discharged onto the sheet discharge tray 169 so as to face the stacking surface of the sheet, the transfer sheets are discharged in the order of the print pages of the originals in the order of reading pages of the original.

When the reading of the document information of the book document 92 is completed as described above, the page turning reading unit 1 moves from the end position position [1C] to the home position position [1A] as shown in FIG. It is moved back toward.

At this time, as shown in FIG. 23, an unequal electric field is generated on the turning conveyance belt 8 due to the charge pattern formed during the reading operation, and this electrostatic field causes the book original 92 to be generated. The page on the right of is electrostatically attracted to the turning conveyance belt 8.

Therefore, in this state, the page turning reading unit 1 is moved toward its end position [1C], and the page turning reading unit 1 is moved to the position shown in FIG.
When the turning start position [1D] shown in FIG.
As shown in FIG. 4, the end portion of one right page original of the book original 92 is wound into the page turning reading unit 1 together with the turning conveyance belt 8.

In this way, the page turning reading unit 1
With the movement of the page-turning reading unit 1, the originals caught in the inside are gradually separated from the turning-conveying belt 8 by the curvature separation of the turning rollers 2 and the waist strength of the originals. To be done.

In this way, the original that is gradually separated from the page-turning conveyor belt 8 is moved along the flipping guide 10 shown in FIG. 20, and the pages are stored on the downstream side in the moving direction of the original. Guided into the section 7.

As shown in FIG. 20, the page accommodating portion 7 is formed in a cylindrical shape, and by winding the document wound in the page turning reading unit 1 along the inner peripheral surface thereof. It is possible to store one page of a document that has been read in a very small space.

Therefore, this page turning reading unit 1
According to FIG. 22, the page turning reading unit 1 is returned from the turning starting position [1D] toward the winding completion position [1E] to finish the reading. The original for the page and the original for the next page to be read by the next reading operation
It can be separated very smoothly.

In the original stored in the page storage section 7 in this manner, the page turning reading unit 1 passes the center of the book original 92 from the winding completion position [1E] and passes the left page of the book original 92. By further returning to the page-discharging position [1F], the page-turning reading unit 1 is moved by the relative movement between the page-turning reading unit 1 and the document stored therein. The page storage unit 7 of No. 1 starts to discharge.

Then, this page turning reading unit 1
However, by returning to the home position [1A] and completing the movement, the discharge of the document stored in the page storage unit 7 of the page turning reading unit 1 is completed, and the reading is completed. The turning operation for one page of the original document is completed.

On the other hand, during the operation of turning over the original, from the time when the winding of the original into the page storage section 7 of the page turning reading unit 1 is started to the time when the winding of the original is completed, the first On the bias roller 3,
By applying an AC voltage for static elimination from the first high-voltage power supply 320 shown in FIG. 20, the electric charge pattern formed on the turning conveyor belt 8 is programmed to be neutralized.

Therefore, this page turning reading unit 1
At the time of the return movement of, since no electrostatic attraction force is generated between the document that has been read and the sheet-turning conveyance belt 8, the document winding operation and the discharging operation are performed. It can be done extremely smoothly.

In the present embodiment, FIG. 20, FIG. 23 and FIG.
As shown in FIG. 4, an AC voltage for adsorption is applied from the high-voltage power supply 320 to the turning conveyor belt 8 which is an endless belt, and an alternating stripe shape or a checkerboard pattern is formed on the surface of the turning conveyor belt 8. By forming a charge pattern such as, an unequal electric field is generated on the turning and conveying belt 8 to hold and convey the original and turn the page.

According to this page-turning method, the document can be held and conveyed, and the page-turning operation can be performed extremely smoothly.

The basic structure of this page-turning method and the principle of electrostatic attraction will be described below. As the page-turning conveyor belt 8 used in this page-turning method, a two-layer structure belt in which the back surface of an endless belt-shaped dielectric material is subjected to a conductive treatment is used.

As means for generating an unequal electric field with respect to the turning conveyance belt 8, for example, the first bias roller 3 rotatably supported by contacting the peripheral surface with the surface of the turning conveyance belt 8, An AC voltage for adsorption may be applied by the first high voltage power supply 320.

As shown in FIGS. 20 and 23, while the conductive layer 8b of the turning conveyance belt 8 is used as a ground plane, an alternating electric field is applied to the first bias roller 3 and the turning conveyance belt 8 and the first bias roller 3 are applied. By moving the roller 3 relative to each other, a stripe-shaped charge pattern is formed on the surface of the dielectric 8a of the turning and conveying belt 8.

As a result, an unequal electric field is generated near the surface of the dielectric 8a of the turning and conveying belt 8. When a dielectric such as a sheet of paper to be read is brought close to this unequal electric field, the inside thereof is polarized, and the electric field is unequal. Works.

As a concrete structure of this embodiment, as the turning conveyance belt 8, an endless film having a thickness of 10 μm and a vapor-deposited aluminum layer (conductive layer 8 b) formed on a PET film (dielectric 8 a) having a thickness of 75 μm is used. A belt was used, and the pitch of the charge pattern formed on the belt was 2.4 mm. That is, the reading speed of the book original 92 is 120 mm /
s, AC frequency is 50 Hz, applied voltage is ± 2 kVp-p
And In addition, FIG. 25 shows experimental values of the pitch characteristics of the conveying force when the applied voltage is fixed to ± 2 kVp-p.
Fig. 27 shows the experimental value of the pitch characteristic of the attraction force when the applied voltage is fixed to ± 2 kVp-p, and Fig. 27 shows the experimental value of the applied voltage characteristic of the carrier force when the pitch of the charge pattern is constant to 2.4 mm. 28, the charge pattern pitch is 2.
The experimental value of the applied voltage characteristic of the attraction force when the constant is 4 mm is shown.

As is clear from these experimental values, the pitch of the charge pattern and the applied voltage used in this embodiment are not limited to the above-mentioned values.
The pitch of the charge pattern is 0.5 mm to 10 mm
Within the range, and the applied voltage is ± 1k
It may be Vp-p or more.

Further, in this embodiment, as the high-frequency AC voltage for static elimination, the frequency of 2 kHz and the applied voltage of ± 2 kVp-p are used, but the static elimination effect can be obtained for each of these values. Any value may be used as long as it is a value.

By the way, in the above embodiment, by applying an AC voltage to the first bias roller 3 by the first high voltage power source 320, the conveyor belt 8 is positively and negatively charged, and the surface of the conveyor belt 8 is charged. It is configured to generate an unequal electric field in the vicinity to hold and convey a document and turn a page.

Here, if the voltage applied to the conveyor belt 8 is an alternating voltage, the original can be sucked, and it is not necessary to limit it to only the AC voltage. That is,
AC voltage is a current that periodically changes its direction,
It means that the average value is “0” over one cycle, and the present invention is not limited to such a voltage.

However, when the voltage applied to the conveyor belt 8 is an AC voltage, a temporary effect that the original attraction force of the conveyor belt 8 is made uniform can be obtained. Therefore,
As a means for generating an unequal electric field in the vicinity of the surface of the conveyor belt 8, a structure other than the above-mentioned embodiment may be used.

For example, as a means for generating an unequal electric field in the vicinity of the surface of the transport belt 8, FIG. 29 and FIG.
As shown in FIG. 0, a checkered pattern is formed on the outer peripheral surface of the bias roller 3-A made of a conductive electrode roller made of metal or the like.
Therefore, a DC voltage may be applied.

According to this means, only the convex portion 3a forming the outer peripheral surface of the bias roller 3-A comes into contact with the surface of the conveyor belt and the concave portion 3b does not come into contact with the surface of the conveyor belt 8. , A checkered high-density charge pattern corresponding to the unevenness of the peripheral surface of the bias roller 3-A is formed.

As a result, at the boundary between the charged area (+ part in FIG. 29) and the non-charged area on the conveyor belt 8 which is a dielectric, there is a stronger electric field than the other parts, and the unequal electric field is generated. The pages of the book document are electrostatically strongly attracted to the transport belt 8 by the strong electric field generated and generated at each edge of the checkered charge pattern.

When the charge pattern is a checkerboard pattern as in the second embodiment, the unit of the checkerboard pattern is a square so that the stripe as in the first embodiment shown in FIG. Since the length of the edge portion existing in the unit area is approximately doubled as compared with the pattern charge pattern, the holding and attracting force of the original page is doubled and the reliability of the page turning operation is improved.

On the other hand, in the second embodiment, the checkered pattern is formed by forming the unevenness on the peripheral surface of the bias roller 3-A. However, for example, printing or printing is performed on the surface of the insulating roller made of resin or ceramic. A checkered conductive layer pattern may be formed by vapor deposition, or a checkered sheet-like electrode may be adhered to electrically connect the conductive layer pattern and the electrodes.

Further, as a third embodiment for generating an unequal electric field in the vicinity of the surface of the conveyor belt 8, as shown in FIG. 31, a charge giving member entirely made of a conductive material such as metal. On the outer peripheral surface of the roller-shaped electrode 3-B, a large number of flange-shaped electrode portions 3c and peripheral groove-shaped non-electrode portions 3d are alternately arranged along the axial direction of the roller-shaped electrode 3-B. Alternatively, a DC voltage may be applied to the roller electrodes 3-B by the first high voltage power supply 320.

According to the third embodiment, as in the first embodiment, the stripe-shaped charges in which the charging regions and the cost-charging regions are linearly alternately arranged on the surface of the conveyor belt 8. A pattern is formed.

On the other hand, in the fourth embodiment shown in FIG. 32, the roller-shaped electrode 3-B is used instead of the above-mentioned roller-shaped electrode 3-B instead of the charge applying means in which the electrode portions 3c and the non-electrode portions 3d are alternately arranged. It is composed of the toothed electrode plate 3-C, and the same operation as that of the third embodiment can be obtained.

In each of the third and fourth embodiments, since the roller electrode 3-B and the electrode plate 3-C are both made of a conductive material, a part of the base material is Although the non-electrode portion 3d is formed by cutting out, for example, by electrically connecting and arranging a large number of conductive portions as the electrode portion 3c on the surface of an insulating roller made of resin or ceramics, The charge applying means may be formed.

As described above, in each of the third and fourth embodiments, the roller-shaped electrode 3-is used for the conveyor belt 8.
Since the structure is such that B and the electrode plate 3-C are arranged opposite to each other, a mechanism for rotationally driving is not necessary, and the cost and the size can be reduced.

By the way, in the stripe-shaped charge pattern thus formed, the charge wraps around from the edge of the electrode portion 3c, so that the width of the charged region tends to be wider than the width of the non-charged region. The electric field at the boundary is likely to be weakened.

In view of this, in these embodiments, the roller-shaped electrode 3- is configured so that the width of the charged area and the width of the non-charged area of the charge pattern formed on the conveyor belt 8 are substantially equal.
The width of B and the electrode portion 3c of the electrode plate 3-C is formed in advance to be larger than the width of the non-electrode portion 3d.

Therefore, according to these third and fourth embodiments, the boundary between the charged area and the non-charged area of the charge pattern becomes clear, and the electric field strength at this boundary can be increased. By making the arrangement pitch of the portions 3c and the non-electrode portions 3d dense and increasing the edge effect thereof, the suction force of the pages of the book document to the transport belt 8 can be increased.

Still another means for generating an unequal electric field near the surface of the conveyor belt 8 is shown in FIG.
As shown in FIG. 3, a DC voltage may be applied to the bias roller 3-D while the switch 320a repeatedly turns on / off the applied voltage of the high-voltage power supply 320, which is a DC power supply.

As described above, the means for generating the unequal electric field is not limited to the AC voltage, but an alternating voltage having a rectangular shape, a triangular shape, a saw shape or the like, or a DC component of the AC alternating voltage. May be superimposed and a voltage biased to either positive or negative may be used.

As described above, according to the page-turning method of this embodiment, it is not necessary to make any work on the paper (book original 92) to be attracted to the turning-conveying belt 8. It is possible to prevent the occurrence of page turning mistakes in the book document 92 due to the occurrence of irregularities (unevenness) at the edges of the sheets without attracting each other.

Further, according to this page turning method, since the portion where the suction force is generated is near the surface of the turning conveyor belt 8, the paper which is in contact with the surface of the turning conveyor belt 8. That is, the page turning of the book original 92 is executed, but for the top original of the paper,
A sufficiently large conveyance force and suction force act, but for the second and lower originals located below this original,
These transporting force and suction force hardly act.

Therefore, according to this page turning method,
Since it is possible to surely perform page turning for only one sheet, this method is an optimum method as a page turning method for the book document 92.

Next, the operation of the MFDS configured as described above will be described. FIG. 34 is an electrical block diagram of the MFDS, FIGS. 35, 36 and 37 are operation mode transition diagrams at the time of reading a book document, FIGS. 35 and 38 are transition diagrams at the time of reading a sheet document, and FIG. 39 is an operation of the MFDS.

Here, in the mode display, only a mode that is possible depending on the capability of the connected device (printer 300) is displayed, or an error is displayed when an impossible mode is selected.

For example, even though a printer that cannot perform double-sided printing is connected, the double-sided mode selection key 61
When the key input of 2 is made, an error message such as "The connected printer cannot be printed on both sides" is displayed.

The reading of the original document is started by the key input of the start key 600 on the operation display board 313. Further, the operation display board 313 and the main control board 310 exchange commands or data by serial communication.

The first image processing board 314 is a Si same-magnification sensor 3 incorporated in the first reading sensor unit 9.

The first high voltage power source 320 is, as described above,
It is a power supply that applies a high-voltage AC voltage to the first bias roller 3, and is configured to be able to generate two frequencies, one for adsorbing a document and one for destaticizing the belt, and switching of each frequency is performed by the main control board 310. This is performed by the switching signals from the two output ports.

The second high-voltage power supply 321 is a power supply for applying a high-voltage AC voltage to the second bias roller 11, similarly to the first high-voltage power supply 320. It is configured to generate frequencies, and switching of each frequency is performed by switching signals from the two output ports of the main control board 310.

The paper feed clutch 128 controls the paper feed start timing of the sheet original 200 based on a control signal from the main control board 310. Further, various sensors 25, 26, 27, 28, 29, 30, 31, 32, which are connected to the respective input ports of the main control board 310,
As described in the above-mentioned mechanism description, 33 and 34 perform mode switching, timing detection, abnormality detection, etc., and give detection signals to the main control board 310, respectively.

Next, the operation mode of the MFDS will be described. The operation mode of MFDS is roughly divided into two modes. The first mode of operation of this MFDS is
A book original reading mode for performing an automatic page turning reading operation of a book original as shown in FIG. 35, and a second operation mode is a sheet for performing an automatic paper feed reading operation of a sheet original as shown in FIG. This is the original reading mode.

The book document reading mode and the sheet document reading mode have subdivided modes. That is, in the book document reading mode, as shown in FIG.
There are an automatic book size recognition mode in which the book size of 2 is automatically recognized, and a book size key input mode in which the book size is designated by a key input on the operation display board 313.

These automatic book size recognition modes,
In each of the book size key input modes, an automatic page-turning reading operation is performed on the book document 92 in a spread reading mode in which the book document 92 is set with the document surface facing upward.

Further, in the book original reading mode, as its reading method, the original images of the left and right two pages of the opened book original 92 are continuously read in association with the output device (especially printer). Using a two-page spread continuous reading mode that prints an image of one page on one sheet of transfer paper and a printer that has a double-sided image forming function, two pages of left and right original images can be read by the two-page spread continuous reading mode described above. This two-page spread continuous reading mode is a two-sided spread mode in which the read images for the next two left and right pages of the book document 92 that has been opened are continuously formed on the back surface of one printed transfer sheet. A reading mode for separating the original images of the left and right pages of the book original 92 by dividing the original image by one page is used. Then, by the printer having the double-sided image forming function, the original images of the left and right pages next to the opened book original 92 are separated by one page on the back surface of the transfer paper printed in the two-page spread one-page division reading mode. The double-sided mode is a double-page spread reading mode.

On the other hand, in the sheet original reading mode, as shown in FIG. 38, the sheet original 200 is automatically fed with the position of the first reading sensor unit 9 or the second reading sensor unit 14 fixed. -Sheet original through mode in which the original image is read by the sheet through method while discharging and moving, and the original placement surface 116

There is a sheet document manual opening / closing mode for manually setting a document when the document cannot be set (or is not set) by the automatic document feeding function (ADF).

In the sheet original through mode, a single-sided reading mode for reading an image on only one side of the sheet original 200 and an image on both sides of the sheet original 200 by the first reading sensor unit 9 and the second reading sensor unit 14 are read. There is a double-sided reading mode for reading simultaneously.

Furthermore, this double-sided reading mode is the first
The reading sensor unit 9 and the second reading sensor unit 14 are arranged at the same position facing each other, and the same position reading mode for reading an original image and the first reading sensor unit 9 and the second reading sensor unit 14 are provided. It has a different position reading mode in which it is arranged at different positions shifted from each other and the original image is read. The operation modes of the MFDS have been described above. Next, switching between the individual modes described above will be described with reference to FIG. 39. In FIG. 39,
When the main power source of the MFDS is turned on, the main control board 310, the turning conveyance belt drive control board 311, the turning unit drive control board 312, the operation display board 313, the first image processing board 314, and the second image processing board shown in FIG. Each 317 is reset and initialization is performed.

After that, the connection of the connected device such as the printer 300 is checked, and the mode applicable to the connected device is displayed, while the number of prints, the scaling factor, the number of pages to be turned, and each mode are set. Accept key input. Further, during this period, the book document 92 or the sheet document 200 is set. Here, the sheet original 20
When 0 is set in the sheet original tray 94,
The sheet document sensor 25 is turned on. In addition, here, the MFD is pressed by the open key 620 of the operation display board 313.
When the transport section 19 of S is opened and the book document 92 is set in the opened state in the central reference positioning section 24 of the document placing surface 116, the book document sensor 27
Is turned on.

According to the ON / OFF state of the sheet document sensor 25 and the book document sensor 27, and the number of prints indicating the number of sheets of the sheet document 200 input by the ten keys 602 of the operation display board 313.
The reading mode of the original image is switched as shown in FIG.

That is, here, the book document sensor 27
Is OFF, the sheet document sensor 25 is ON, and the number of prints is “1”, the sheet document through mode is entered. Further, here, the book document sensor 27 is turned on.
When the FF and the sheet document sensor 25 are ON and the number of prints is “2” or more, the sheet document scan mode is entered.

Further, when both the book original sensor 27 and the sheet original sensor 25 are OFF, the sheet original manual opening / closing mode is entered. When the book original sensor 27 is ON and the sheet original sensor 25 is OFF, the book original reading mode is entered.

Further, here, the book original sensor 27,
If both of the sheet document sensors 25 are ON, the abnormality processing 1 (warning buzzer ON and error display)
Then, the user is warned, and then the book manuscript reading mode is entered.

In this way, if the start key 600 of the operation display board 313 is not pressed after entering the selected mode subroutine, the image reading operation is not executed and the process returns to the step of accepting the key input. To be done.

Next, the operation of each mode described above will be described. First, the book document reading mode will be described with reference to FIG. The MFDS mode is
When the book document reading mode is entered, ON / OFF of the scan cutoff sensor 34 is checked.

As shown in FIG. 4, the scan cut-off sensor 34 detects the upper limit detector 76 when the page turning reading unit 1 moves up to its upper limit position, and is turned on. The page turning reading unit 1
As described above, the book document 92 is moved up and down according to the thickness of the book document 92 placed on the document placing surface 116. This page-turning reading unit 1 is raised, that is, the book document 92.
As the thickness increases, the tension of the turning conveyor belt 8 that drives this increases.

Therefore, if the tension of the page-turning conveyor belt 8 becomes too high, that is, if the book original 92 is too thick and the page-turning reading unit 1 rises too much,
This tension acts as a brake, and the page turning reading unit 1 cannot scan.

The scan cutoff sensor 34 detects such a level at which the page turning reading unit 1 cannot scan because the book document 92 is too thick. When the scan cut-off sensor 34 is ON, abnormal processing 2 (warning buzzer ON and error message "book original is too thick" is displayed), and the user forcibly closes the transport unit 19, The transport section 19 is prevented from being damaged.

Here, when the thickness of the book document 92 is equal to or less than the adaptive level, the user closes the carrying section 19 to turn on the carrying section lock sensor 31. At this time, if the transport unit 19 remains open, that is, if the transport unit lock sensor 31 remains OFF, error processing 3 (alarm buzzer ON, "Please close the transport unit")
Is displayed).

When the carrying section 19 is closed,
The ON / OFF of the book size upper limit sensor 33 is checked. Here, the book size upper limit sensor 33 is
When the book size of the book document 92 is detected and turned on, that is, the book size of the book document 92 set on the document placement surface 116 exceeds the reading area of the page turning reading unit 1 and cannot be read. Error handling 4 (warning buzzer ON
"The size of the book document is too large" is displayed.

After that, after checking the presence or absence of key input of the number of prints, the scaling factor, and the number of pages to be turned, in the case of the automatic book size recognition mode, the prescan flag is set and the automatic book size recognition mode is not set. In this case, the book size input mode is entered and the operation display board 3
A reading area of the book document 92 is determined by setting a book size by inputting a predetermined key with the key 13.

Then, when the start key 600 is pressed, the transport section locking device 140 operates and the transport section 19 is locked to the document table 18. As a result, during the page turning operation by the page turning reading unit 1, the user mistakenly opens the conveying section 19 and the book document 9
A situation that damages 2 is avoided.

Next, after the operation of the transport unit locking device 140, if the above-mentioned prescan flag is set, the prescan operation of the page turning reading unit 1 is executed. Here, if the prescan flag is not set, this prescan operation is skipped.

After the prescan operation, the apparatus waits until the connected device (printer 300) is ready. And
When the reading start signal output from the connection device (printer 300) is received when the connection device (printer 300) is ready, the page turning reading unit 1 is driven and, as described above, the book document 92. The operation of reading the original image is started.

The reading operation by the page turning reading unit 1 is repeated a number of times corresponding to the previously set number of prints. When the reading operation of the predetermined number of times is completed, the page turning reading unit 1 executes the page turning operation as described above in order to perform the reading operation of the original image of the next page.

In this way, the reading operation of the original image of the book original 92 and the page turning operation are repeatedly executed until the final page is turned in accordance with the preset number of copies. Then, the page turning operation of the preset final turning page is completed,
Moreover, when the reading operation for the final read page is completed a predetermined number of times, the page turning reading unit 1 does not perform the page turning operation of the final reading page,
After returning to the home position [1A], the book document reading mode routine is returned.

The basic operation of the book original reading mode is as follows.
As described above with reference to the flowchart shown in FIG. 40, the two-page spread continuous reading mode, the two-sided mode, and the one-page spread reading mode and the two-sided mode in this mode are as shown in FIG. It becomes the input mode accepted when the key input is set.

Each of these input modes will be described with reference to the timing chart showing the progress after the start key 600 is pressed. First, the spread two-page continuous reading mode will be described with reference to the timing chart shown in FIG.

In FIG. 41, when the start key 600 of the operation display board 313 is pressed and the reading start switch SW is turned on, the shutter (not shown) in the first reading sensor unit 9 is closed. The inner surface of this shutter serves as a white reference plate, by which the shading correction of the first reading sensor unit 9 is performed.

This shading correction is performed every time the page turning reading unit 1 rises, and is completed before the moving speed of the page turning reading unit 1 reaches a constant speed (a timing chart of this portion is not shown). This page turning reading unit 1 starts from the main control board 310 to the page turning unit drive control board 3
This is performed by the forward rotation start signal sent to 12.

By this forward rotation start signal, the page turning reading unit 1 starts prescanning. Here, after the moving speed of the page turning reading unit 1 rises to the constant speed Vf, the above-mentioned shutter is already opened, and the reading of the original image of the book original 92 is started by the first CCD 315.

The book original 92 opened by the pre-scanning of the page-turning reading unit 1 is opened.
The edge size of the book document 92 set on the document placing surface 116 is recognized by detecting the edge of the document by image processing and counting the output of the encoder 152 attached to the turning roller 2 at this time. , The reading area of the original image of the page turning reading unit 1 and the page turning area are determined.

As described above, in this MFDS, since the book original 92 is set with the center of the original placing surface 116 as a reference, only the left end portion of the set book original 92 is detected. Thus, the reading area of the original image of the page turning reading unit 1 and the page turning area can be calculated.

Therefore, in this MFDS, the book original 9
When detecting the book size of 2, the page turning reading unit 1 does not need to be pre-scanned on the entire surface, and only the page turning reading unit 1 is short pre-scanned, and the book of the book document 92 placed on the document placing surface 116 is read. The size can be detected.

This prevents the reading start page of the book original 92 from being mistakenly turned over during the prescanning of the page turning reading unit 1.

Book size data of the book original 92 is transmitted from the main control board 310 to the printer 300 as an externally connected device.

On the other hand, while the book size detection is completed and the book size data is being transmitted to the printer 300, the main control board 310 drives the turning unit drive motor 60 to the turning unit drive control board 312. A reverse rotation signal for reverse rotation is given, and the page turning reading unit 1 is moved back to its home position [1A] at the speed Vr.

The original placement surface 116 of the original table 18 of the MFDS is colored by a chromatic color, for example, a chromatic color such as yellow which is not often used as a book original. Since the area identification accuracy between the original placement surface 116 and the reading area of the original image of the book original 92 can be improved, the book size can be detected more accurately during the above prescan, and the book can be detected. The reliability of size data is improved.

If the document mounting surface 116 is colored with an intermediate color such as gray, the first CCD 315 of the first reading sensor unit 9 does not use a color sensor and prescanning is performed. Area can be identified. After the above-described prescan is completed and the page turning reading unit 1 is retracted to the home position position [1A], the printer 300 is ready and the printer 300 is ready.
When a transfer request signal for requesting data transfer is given from the main control board 310 from the main control board 310, the main control board 310 causes the turning unit drive motor 60 to rotate forward with respect to the turning unit drive control board 312. A normal rotation signal is given, and the normal rotation operation of the page turning reading unit 1 is started.

In the page turning reading unit 1, as described above, the output of the encoder 152 of the turning roller 2 is fed back, so that the book original 92 is fed.
Along the document surface, the speed is controlled to the speed of Vf, and the document is moved toward the end position [1C].

At this time, the first reading sensor unit 9
The LED 316 has already been turned on, and the first CCD 315 of the first reading sensor unit 9 has started reading the document information of the book document 92.

Here, as shown in FIG. 1, the document placing surface 1
In the vicinity of the binding portion (center portion) of the book original 92 that is opened and set on the sheet 16, the original surface is warped,
It becomes difficult to accurately read the document information near the binding portion. In addition, near the binding portion of the book document 92,
Normally, document information such as characters and images is not formed.

Therefore, in this MFDS, as shown in FIG. 41, the reading SFGATE of the first CCD 315 is turned off near the binding portion of the book document 92,
Reading of the document information near the binding portion is masked.

The mask area at the time of initial setting of the original information is set to be +10 mm and -10 mm from the center of the central reference positioning portion 24 as described above, but this mask area is set on the operation display board. 313
The set value can be changed by key input of the book binding portion mask area setting key 608, and it is possible to deal with a book original with a special binding.

By the way, the first reading sensor unit 9
When the document information of the book document 92 is read by the page turning reading unit 1, the page turning reading unit 1 reads the end position [1
C], the first high voltage power supply 320 is turned on at the frequency f1 when the page turning reading unit 1 reaches the vicinity of the center of the book document 92.
As a result, the above-described charge pattern is formed on the portion of the turning conveyance belt 8 that abuts the right page of the book document 92.

As described above, the page-turning conveyor belt 8 is not driven when the page-turning reading unit 1 is driven, and serves to hold the book document 92. In this way, the page turning reading unit 1
When the drive is driven to the end position [1C] and the reading of the document information up to the reading area at the right end of the book document 92 is completed, the output of the first high-voltage power supply 320 becomes O.
At the same time as FF, the main control board 310 supplies a turning signal to the turning unit drive control board 312, and the page turning operation of the book document 92 by the page turning reading unit 1 is started.

At this time, if the document surface read by the first reading sensor unit 9 corresponds to the preset last read page of the book document 92, the main control board 310 outputs a turning signal. First, the page-turning reading unit 1 uses the book original 92.
After the last read page is read, the document is returned and moved without performing the page turning operation described above, and is retracted to its home position [1A].

During the page-turning operation of the book document 92, the reverse-turning operation of the page-turning reading unit 1 is slow-started until the page-turning sensor 29 is turned on, and electrostatically adsorbed on the turning-conveying belt 8. The read-finished page (the right page in FIG. 1) of the book original 92 is guided into the page storage unit 7.

Then, the page turning reading unit 1
The book document 92 is further returned and moved toward the home position 1-A, and up to the center portion of the read-finished page of the book document 92 is folded into the page storage section 7.

During the page turning operation of the page turning reading unit 1, the first high-voltage power supply 320 is turned on at the frequency f2 in order to eliminate the charge pattern in the document suction area of the page turning conveyance belt 8.

In this way, the book original 9 turned into the page storage portion 7 of the page turning reading unit 1
The second page to be read is discharged from the page storage section 7 until the page turning reading unit 1 reaches the end position position [1C] after the page turning reading unit 1 passes over the center section of the book original 92 and turns the page. The operation is completed.

The return speed Vrm of the page-turning reading unit 1 at the time of discharging the page is set to be higher than the speed Vf at the time of reading the original, that is, Vrm> Vf. The operation speed is increased.

The state of this series of page turning operations is detected by the page turning sensor 29. That is, this MFDS detects the presence / absence of an abnormality by checking ON / OFF of the page-turning sensor 29 at each position of the page-turning reading unit 1, and when there is an abnormality, an abnormality handling operation is executed.

As the abnormal processing operation, the warning buzzer is activated, and, for example, when the original page cannot be turned into the page storage section 7, "page turning is impossible", the page storage section 7 is turned over. If the original pages cannot be ejected, a message such as "Page cannot be stacked" will appear.
This is displayed on the operation display board 313, and the page turning operation is stopped.

Further, in order to allow the user to confirm the page-turning state where this abnormality has occurred, the location where the page-turning state abnormality has occurred is indicated on the operation display board 313.
Displayed in.

The reading and page turning operations of the second and subsequent pages of the book original 92 are sequentially started by the transfer request signal from the printer 300, and the same reading operation and page turning as described above are performed. The operation is repeatedly executed until the final read page set in advance is reached.

Here, in the timing chart of FIG. 41, when the number of prints of the original is set to "1", that is, each read page of the book original 92 is set to 1
The case where the page-turning operation for the pages that have been read is executed each time the document is read is shown. However, if the number of prints of this document is set to "2" or more,
At the time when the first original reading operation by the reading sensor unit 9 is completed, a reverse rotation signal is transmitted from the main control board 310 to the turning unit drive control board 312 instead of the turning signal, and the page turning reading unit 1 operates. At the speed of the speed Vr, the home position position [1A] is returned, and at the same time when the return operation is completed, the second original reading operation of the page turning reading unit 1 is started.

Then, the document reading operation of the page turning reading unit 1 is repeatedly executed by the preset number of print sets of the document, and when the number of this operation and the number of print sets match. Then, for the first time, a turning signal is transmitted from the main control board 310 to the turning unit drive control board 312, and the page turning operation described above is executed.

Hereinafter, the reading of the original image of the second and subsequent pages of the book original 92 and the page turning operation are sequentially started in response to the transfer request signal from the printer 300, and the number of times corresponding to the same number of printing units as the above is performed. The reading operation and the page turning operation are repeatedly executed until the final read page set in advance is reached.

If the print scaling key 614 is set to scale the read original image, the scanning speed Vf of the first reading sensor unit 9 is set to the scaling ratio. By changing the speed according to the speed, the document image is scaled in the sub-scanning direction, and at the same time, the first image processing board 314 scales the document image in the main scanning direction.

On the other hand, in the double-sided two-page spread continuous reading mode as described above, the printer 30
0 performs double-sided printing of the original image, so that the transmission timing of the transfer request signal from the printer 300 to the main control board 310 is slightly delayed, but regarding other operations, the above-described two-page spread consecutive pages are used. The same operation as the reading mode is executed.

Next, with reference to FIG. 42, the spread one page break reading mode will be described. This spread 1
The page break reading mode is a mode in which the left page and the right page of the book document 92 that has been opened are separately read to form an image, and a mode in which each of these images is printed on a separate transfer sheet and one page There is a mode of printing on the front and back sides of the transfer paper (double-sided mode of this double-page spread page reading mode).

In this mode, either one of the operation of reading from the left page of the book document 92 and the operation of reading from the right page of the book original 92 is performed.
The reading start page selection key 603 can be selected and set. FIG. 42 shows a timing chart when the reading is started from the left page toward the book document 92.

The operation of the double-page spread one-page break reading mode is substantially the same as the operation of the double-sided mode of the double-page spread two-page continuous reading mode described above. The transfer request signal from the printer 300 to the main control board 310 is transmitted page by page, which allows the page turning reading unit 1 to move from the left page of the book document 92 to the right page. It is moved (scanned) at high speed.

FIG. 43 shows a timing chart in the case where the reading is started from the right page of the book document 92 in the double-page spread page reading mode.

As is apparent from this timing chart, when the reading is started from the right page of the book original 92, the moving speed of the page turning reading unit 1 with respect to the left page where the book original 92 is not read is , And is programmed to be faster than the scanning speed Vf of the first reading sensor unit 9 for the right page, so that the document reading time is shortened, that is, the reading function is improved.

In the two-page spread single page break reading mode, the read skip page setting key 61
If a page to be skipped without scanning (skipping) is set by 8, the page turning reading unit 1 for the reading skip page is
It is programmed to move at a speed higher than the scanning speed Vf of the first reading sensor unit 9 at the time of reading and immediately execute the reading skip page turning operation (a timing chart is not shown). ).

By the way, generally, FIG. 42 and FIG.
As shown in FIG. 5, few printers can continuously request the transfer request signal from the printer 300 to the main control board 310 in the normal state.

Therefore, in the case of carrying out the double-page spread page break reading mode by using such a general printer, two transfer sheets are fed so as to be overlapped on the printer side. It can be realized by

If it is necessary to provide a certain distance between these two transfer sheets due to the resist relationship between the transfer sheet and the photosensitive drum, the book original 92 is used. The image data on the left side of the page is sent to the printer as it is, and the image data on the right side of the book document 92 is delayed through the delay memory for the time corresponding to the distance between these transfer sheets. Can be realized by.

A block diagram of an example of this latter case is shown in FIG.
4 and the timing chart thereof are shown in FIG.
In this example, the internal gates A and B on the main control board 310 delay the image data output to the printer through the delay memory by the time Td with respect to the image data directly output to the printer through the switch. Is configured to be.

Next, the double-sided mode in the double-page spread single page break reading mode will be described. First, a case will be described in which the image data of the left and right two pages of the opened book document 92 is printed on the front and back sides of one transfer sheet.

In this case, since it is necessary to reversely convey the transfer paper on the printer 300 side, after the printing of the image data of the left page is completed and before the printing of the image data of the right page is started, It will take some time.

Therefore, in this mode, when the page turning reading unit 1 finishes reading the left page of the book original 92 and reaches the vicinity of the binding portion, the driving of the page turning reading unit 1 is temporarily stopped. It

Then, the printing of the left page image on the printer 300 side and the reverse conveyance of the transfer sheet are completed,
When a transfer request signal is output from the printer 300 to the main control board 310, the stopped page turning reading unit 1 is driven again at a predetermined scan speed Vf,
The right page of the book document 92 is read, and the image data of this right page is transferred to the printer 300.
On the back side of the transfer paper with the left page image printed on the front side,
This right page image is printed and double-sided printing is performed. FIG. 46 shows a timing chart at this time.

Next, a description will be given of the double-sided mode in the case of forming an image by matching the relationship between the front and back sides of the printed transfer paper and the front and back sides of the document surface of the book document 92 in the two-page spread one-page division reading mode. .. In this mode, when reading is started from the left page of the book document 92, the printer 300 is instructed to continuously feed two sheets, and the left page image is printed and transferred as described above. While the paper is discharged as it is, the transfer paper on which the right page image is printed is reversed and conveyed, and preparation is made for printing the left page image of the next page of the book document 92 on the back surface thereof.

During this time, on the MFDS side, the page turning operation is performed on the manuscript pages that have been read. When the page turning operation on the MFDS side is completed, the reading operation for the next page is executed, and before,
The read left page image is printed and ejected on the back surface of the transfer sheet on which the right page image is printed and reversed and conveyed.

The right page image read at this time is printed on a newly fed transfer sheet. This transfer paper is reversely conveyed like the previous transfer paper, and preparations are made for printing the left page image of the next page of the book document 92 on the back surface thereof. By repeating such a series of operations, a transfer sheet on which an original image having the same page configuration as the book original 92 is printed can be obtained. The above is an example of the operation in the book document reading mode.

Here, the setting of a book document in the spread reading mode will be described. In the connected device check of FIG. 34, if the printer 300 can eject the back surface, the following display is performed.

That is, "If the book document is written horizontally (open left), open the front page you want to read and set it face up.""If the book is written vertically (right open), read the first page you want to read. Please open your eyes and set it upside down. ”Instructing each setting method for horizontal writing and vertical writing of the book manuscript.

On the other hand, in the connected device check of FIG. 34, when the printer 300 is only capable of front surface paper ejection, the following display is made.

[0308] That is, "If the book document is written horizontally (open left), open the last page you want to read and set it upside down.""If the book document is written vertically (right open), read the final page you want to read. Please open the page and set it so that it is facing upward. ”You will be instructed how to set the book manuscript horizontally and vertically.

In this MFDS, by setting the book original 92 according to the above-mentioned instruction, the pages of ejected transfer paper can be aligned regardless of the function of the printer 300 connected thereto. In addition, as for the method of inputting the number of pages to turn in this MFDS,
There are two input methods by key input on the operation display board 313, and the user can select any one of these input methods according to his / her preference. One of the input methods is the read total page setting key 606.
Etc. is used to set the total number of pages to be read. Another input method is to use the read start page setting key 604, the read last page setting key 605, etc. This is how to enter a page.

No matter which of the above-described methods is used to input the number of page-turning pages in this MFDS, it is sufficient that the page-turning number of the page-turning reading unit 1 can be accurately calculated. The method of calculating the number of page turns in each of the above methods will be described below. First, the case where the total number of pages to be read is input will be described.

Here, if the total number of pages to be read is X and the number of pages to be turned is M, when reading from the left page, (X-2) / 2 = M + remainder ... When reading from the right page Is (X-1) / 2 = M + remainder ... By calculating the value of M from these equations, the number of times of turning can be obtained.

Next, the case where the first page to be read and the last page are input will be described. Here, if the first page to be read is Y, the last page is Z, and the total number of pages to be read is X, then X = Z−Y + 1 ... As a result, the number M of turnings can be calculated.

By the way, as described above, this MFDS is configured so that a single apparatus can selectively read a book original and a sheet original and form an image thereof. The image reading mode for the book original is as described above, and the image reading mode for the sheet original in this MFDS will be described below.

As shown in FIG. 38, the sheet original reading mode includes a sheet original through mode, a sheet original scan mode, and a sheet original manual opening / closing mode.

First, the sheet original through mode will be described. The sheet original through mode includes a single-sided original reading mode and a double-sided original reading mode. The double-sided original reading mode includes a same-position reading mode and another-position reading mode.

Selection of these modes is performed as shown in FIG. First, in the single-sided original reading mode, as shown in FIG. 48 and FIG.
4, the sheet original 200 is set downward, and when the start key 600 is pressed in this state, first, the power source of the turning conveyance belt drive motor 61 is turned on, the driving roller 12 is rotated, and the turning conveyance belt 8 is rotated. Is rotated.

At this time, if there is no abnormality in each sensor and each input data, the sheet feeding clutch 128 is turned on, and the second sheet feeding pulley 13 attached to the first belt supporting roller 97.
0 to the paper feed roller 96 via the paper feed drive belt 127.
Is rotated, and the sheet original 200 is conveyed toward the paper feed separation pad 95.

The sheet feeding / separating pad 95 separates only the lowest one sheet original 200 from other sheet originals, and the first conveying guide 108 and the second conveying guide 10 are separated.
While being guided by 9, the sheet is conveyed to a position in contact with the turning conveyance belt 8.

Here, in this second conveyance guide 109,
A paper feed sensor 26 is attached, and the paper feed sensor 2
6, the conveyance timing of the sheet original 200 is set so that the sheet feeding clutch 128 is turned off after the trailing edge of the sheet original 200 is detected.

On the other hand, during this period, a high AC voltage is applied from the AC power supply to the second bias roller 11 as the turning conveyor belt 8 rotates, and a striped charge pattern is formed on the turning conveyor belt 8. As a result, the fed sheet original document 200 is sucked and conveyed by the turning conveyance belt 8. The linear velocity of the turning conveyance belt 8 at this time is changed to 360 mm / s at the same magnification and according to the set magnification at the time of changing the magnification.

On the other hand, in this mode, the page turning reading unit 1 is positioned at the end position position [1C], and the first reading sensor unit 9 moves the sheet original 2 conveyed by the turning conveying belt 8.
00 document information is sequentially read (pixel density is 400
dpi).

Then, the sheet original 200 having been read is read by the third conveyance guide 110 and the fourth opposing roller 1.
03, fifth opposing roller 104, sixth opposing roller 105,
The sheet is nipped and conveyed by the seventh opposing roller 106, and is ejected from the ejection port 117 onto the ejection tray 23.

A paper discharge sensor 28 is attached to the third conveyance guide 110 near the paper discharge port 117, and a paper discharge jam of the discharged sheet original 200 is detected. When the reading operation of the first sheet document 200 is completed, next, at a predetermined paper feed timing,
The paper feed clutch 128 is turned on again, the second sheet document 200 is fed, and the reading operation similar to that described above is executed.

In this way, the sheet originals 200 set on the sheet original tray 94 are sequentially fed and read, the last (topmost) sheet original 200 is fed, and the sheet original sensor 25 is turned off. Then, the power source of the second bias roller 11 is switched to the high frequency AC voltage,
After the charge pattern on the turning and conveying belt 8 is removed and the final sheet original 200 is discharged, all the operations of the MFDS are stopped. The above reading operation is based on this M
This is an operation in the case where a printer having a back surface paper ejection function is connected to the FDS, and thereby page alignment paper ejection of the sheet original 200 and the printed transfer paper is realized.

If the printer connected to the MFDS has only the front surface discharge function, the sheet original 200 is set upward on the sheet original tray 94, and the second reading sensor unit is set. By 14,
By reading this sheet original 200, as in the case of the printer having the back surface discharge function described above,
The page original discharge of the sheet original 200 and the printed transfer paper is realized. Further, other operations when the printer having the front surface discharge function is connected are the same as those when the printer having the back surface paper discharge function is connected.

Next, the double-sided document reading mode in the sheet document through mode will be described. In the double-sided document reading mode, a horizontally-written sheet document is set on the sheet document tray 94 with the leading edge of the document facing downward.

This is because the first reading sensor unit 9 and the second reading sensor unit 14 do not have a memory, so only mirror reversal in the main scanning direction can be used.

First, the basic operation of the same-position reading mode in this double-sided original reading mode is the same as in the single-sided original reading mode as shown in FIGS. 50 and 51, but in this mode, page turning is performed. When the reading unit 1 is located at its home position [1A] and the document table 18 is at the same position as the second reading sensor unit 14, the reading of the document information on both the front and back sides of the sheet document 200 is performed. First reading sensor unit 9 and second reading sensor unit 14
By being executed in parallel at the same time.

On the other hand, the basic operation of the different position reading mode in this double-sided original reading mode is as shown in FIG.
As shown in FIG. 53, this is similar to the case of the single-sided original reading mode, but in this mode, the page turning reading unit 1 is located at its end position position [1C].

As is clear from this, in this different position reading mode, the first reading sensor unit 9 and the second reading sensor unit 9 are
Since the distance between the reading position of the reading sensor unit 14 and the reading position is larger than the length of the maximum size original, the sheet original 200 read by the first reading sensor unit 9 and the second reading sensor unit 14 is read.
The document information on both the front and back sides is output in time series.

Next, the sheet scan mode in the sheet original reading mode will be described. In this sheet scan mode, as shown in FIGS. 54 and 55, when the sheet document 200 is set upward on the sheet document tray 94, and the start key 600 is pressed in this state, first, the turning conveyance belt is started. The power source of the drive motor 61 is turned on, the drive roller 12 is rotated, and the turning conveyance belt 8 is rotated.

At this time, if there is no abnormality in each sensor and each input data, the paper feed clutch 128 is turned on, and the second paper feed pulley 13 attached to the first belt support roller 97.
0 to the paper feed roller 96 via the paper feed drive belt 127.
Is rotated, and the sheet original 200 is conveyed toward the paper feed separation pad 95.

The sheet feeding / separating pad 95 separates only the lowest sheet original 200 from other sheet originals, and the first and second conveyance guides 108 and 10 are separated.
While being guided by 9, the sheet is conveyed to a position in contact with the turning conveyance belt 8.

Here, in this second conveyance guide 109,
A paper feed sensor 26 is attached, and the paper feed sensor 2
6, the conveyance timing of the sheet original 200 is set so that the sheet feeding clutch 128 is turned off after the trailing edge of the sheet original 200 is detected.

On the other hand, during this period, a high AC voltage is applied to the second bias roller 11 from the AC power source as the turning conveyance belt 8 rotates, and a striped charge pattern is formed on the turning conveyance belt 8.

As a result, the fed sheet original 200 is sucked and conveyed by the turning conveyance belt 8. The linear velocity of the turning and conveying belt 8 at this time is 360
The setting is set to mm / s, and when the leading edge of the sheet document 200 reaches the home position position [1A], the turning of the turning conveyance belt 8 is stopped.

On the other hand, in this mode, the page turning reading unit 1 is located at its home position [1A], and after the turning of the turning conveyor belt 8 is stopped, the page turning reading unit 1 is turned over. The end position position [1
The original information of the sheet original 200 conveyed by the turning conveyance belt 8 is sequentially read by the first reading sensor unit 9 while moving toward C] (pixel density is 400 dpi).

At the time of reading this document information, a high-frequency AC voltage is applied to the first bias roller 3 by the first high-voltage power supply 320, and the charge pattern formed on the turning conveyance belt 8 is eliminated. As a result, the sheet original 200 at the time of the return movement of the page turning reading unit 1
Entry into the page turning reading unit 1 is prevented. The page turning reading unit 1 which has finished reading the sheet document 200 in this way is returned toward its home position [1A].

When the page turning reading unit 1 returns, the first reading sensor unit 9 is retracted upward from the original surface of the sheet original 200, and
A high-voltage AC voltage is applied to the first bias roller 3 from the first high-voltage power supply 320, and a striped charge pattern is formed on the turning conveyance belt 8, and the sheet original 200 is formed.
The peeling and conveying belt 8 is attracted and fixed.

After the above-described operation is repeated the set number of times, the turning conveyance belt drive motor 61
Is turned on, the turning conveyance belt 8 is rotated, and the sheet document 200 that has been read is discharged from the paper discharge port 117 onto the paper discharge tray 23.

A paper discharge sensor 28 is attached to the third conveyance guide 110 near the paper discharge port 117, and a paper discharge jam of the discharged sheet original 200 is detected. When the reading operation of the first sheet document 200 is completed, the sheet feeding clutch 128 is turned on again at a predetermined sheet feeding timing, and the second sheet document 200 is fed, The reading operation similar to that described above is executed.

In this manner, the sheet originals 200 set on the sheet original tray 94 are sequentially fed and read, the last (topmost) sheet original 200 is fed, and the sheet original sensor 25 is turned off. Then, the power supply of the second bias roller 11 is switched to the high-frequency AC voltage of the second high-voltage power supply 321, the charge pattern of the turning conveyance belt 8 is removed, and the final sheet original 200 is discharged, and then the MFDS All operations are stopped.

Next, the sheet original manual opening / closing mode in the sheet original through mode will be described. The operation of the sheet document manual opening / closing mode is shown in FIGS.
As shown in FIG. 7, in the operation of the above-described sheet document scanning mode, the sheet conveying unit and each power supply for sheet suction are turned off, and the operator manually replaces the sheet document.

The operation control of the page turning reading unit 1 in this MFDS will be described below. Fig. 58
The page-turning reading unit 1 in this MFDS
The operation control circuit of is shown.

This operation control circuit controls the reciprocating drive of the page turning reading unit 1 and its speed control, and is incorporated in the turning unit drive control board 312. In FIG. 58, a microcomputer 52
0 (hereinafter, simply referred to as a microcomputer) also performs mode control and sequence control of this MFDS (details not shown).

As such a microcomputer 520, for example, a programmable interval timer 521 (hereinafter, simply referred to as a timer) based on μPD71054G is connected. The timer 521 controls the turning unit drive motor 60 (DC motor) under the control of the microcomputer 520.
The pulse width modulation PWM output for performing the speed control of is output.

The cycle of this PWM control is 50 (μsec)
And this is controlled with a resolution of 400 bits. An 8 MHz oscillator 522 is connected to the timer 521 and is configured to be supplied with a clock signal.
Further, the turning unit drive motor 60 includes a microcomputer 52
0 is connected to 0 through driving transistors Q1 to Q4.

That is, the transistors Q1 and Q4 are turned on.
When the transistors Q2 and Q3 are OFF, the turning unit drive motor 60 is supplied with a current that rotates clockwise (CW), and the transistors Q2 and Q3 are ON.
Then, when the transistors Q1 and Q4 are off, the turning unit drive motor 60 is supplied with a current that rotates counterclockwise (CCW).

Here, the turning unit drive motor 60
However, when rotated in the clockwise direction (CW), the page turning reading unit 1 is moved forward, and the page turning unit drive motor 60
However, the page turning reading unit 1 is set to be moved back when it is rotated counterclockwise (CCW).

The rotation direction of the turning unit drive motor 60 is controlled by the CW signal and the CCW signal output from the ports PF6 and PF7 of the microcomputer 520, respectively. Further, the turning roller 2 is directly connected to an encoder 152 that generates a pulse in accordance with the rotation thereof.

Here, the encoder 152 generates two pulse signals having different phases according to the rotation amount and the rotation direction of the turning unit drive motor 60. One is the A-phase encoder pulse ENCA, and the other is the B-phase encoder pulse ENCB. The A-phase encoder pulse ENCA is input to the counter input terminal C1 of the microcomputer 520 via the frequency division multiplexer 524.

As a result, the microcomputer 520 determines that the pulse interval of the A-phase encoder pulse ENCA is
Is measured by an internal counter (regulated by the oscillation frequency 10 MHz of the oscillator 525 of the microcomputer 520).

The input signal to the counter input terminal C1 is an interrupt input, and the value of the measurement data of the pulse interval of the A-phase encoder pulse ENCA is read during the processing of the interrupt program, and based on this data. Then, the rotation speed of the turning unit drive motor 60 is calculated, the motor control amount is calculated by the proportional / integral control calculation, and
Output (data loading to the timer 521) and the like are performed.

Specifically, the A-phase encoder pulse ENC
The output of A is divided by the frequency division multiplexer 524 according to the target speed.
By dividing the frequency by 1, 2, 4, or 8, an interrupt input signal is applied to the counter input terminal C1.

Here, when the frequency is divided by 1, the first reading sensor unit 9 moves 0.116 mm by one pulse of the encoder 152, and the speed thereof is calculated in the microcomputer 520 by the interrupt interval. Then, the output timer value is determined by the proportional / integral calculation process based on the calculated speed data.

Further, the A-phase encoder pulse ENCA and the B-phase encoder pulse ENCB are input to the input terminal PC3 of the microcomputer 520 via the flip-flop 526, and are used for detecting the phase difference between them, and their positions are detected. The rotation direction of the turning unit drive motor 60 is determined by the phase difference.

That is, when the A-phase encoder pulse ENCA rises, the state of the B-phase encoder pulse ENCB is input to the port of the microcomputer 520 to determine the rotation direction of the turning unit drive motor 60.

Next, speed control of the turning unit drive motor 60 will be described. The speed control of the turning unit drive motor 60 is performed by PWM control. First, when the page turning reading unit 1 scans the scanner, that is, when the turning motor 60 rotates clockwise, the transistor Q1 is turned on, while the PWM output from the timer 521 causes the transistor Q4 to pass through the gate 527. ON / OFF to generate a potential difference between both terminals of the turning unit drive motor 60,
The turning unit drive motor 60 is rotated at a speed according to the duty ratio of the PWM signal.

On the other hand, when the page turning reading unit 1 returns, contrary to the above case, the transistor Q3 is turned on.
In addition, the PWM output from the timer 521 causes the transistor Q2 to turn on through the gate circuit 528.
The turning unit drive motor 60 is turned on / off to generate an opposite potential difference between both terminals of the turning unit drive motor 60, and the turning unit drive motor 60 is rotated at a speed corresponding to the duty ratio of the PWM signal.

The copyright management support system in the MFDS configured as described above will be described below. First, referring to FIG. 59, the internal configuration and functions of the main control board 310 of the MFDS will be described.

In FIG. 59, a one-chip microcomputer 330 (hereinafter, simply referred to as a microcomputer) has a structure including an internal RAM, an internal ROM, an I / O, a timer, an external / internal interrupt, a serial interface and the like. In addition, an external R
External devices such as the OM 331 and the external RAM 332 can be accessed.

The external ROM 331 is a microcomputer internal ROM.
As well as the operating program is incorporated. External RA
The M332 can store setting data and the like to an external device, and is backed up by a battery backup battery 334 so that it can be stored in memory even when the power of the apparatus is turned off.

Serial interfaces 337 and 33
Reference numerals 8 and 339 are serially connected to an external unit, an external device, etc., and can transmit and receive commands and data to and from the one-chip microcomputer. The ID card reader 340 reads magnetic data and the like incorporated in a card issued to an individual or a group, encodes the data, and inputs the encoded data to the microcomputer via the serial interface 338. With this data, it is possible to determine who copied the book document.

The bar code reading device 341 is a book manuscript identification device for identifying the kind of the book manuscript based on the bar code pattern attached or printed on the book manuscript such as a book or magazine.

In this embodiment, the bar code reading device 341 is shown as the book document identifying device, but it may be a device for identifying the magnetic pattern attached to the book document.

The bar code reading device 341 comprises a bar code scanner and bar code data. In this example, the bar code scanner uses a CCD, but the bar code scanner may be a pen type using a reflected light sensor or a laser scan type scanner.

The bar code data read by this CCD scanner has its bar code signal converted into ASCII code, and serially communicated to the main control board 3.
It is sent to 10. Operation display board 3
Reference numeral 13 performs mode setting and display, operation procedure display, error display, and the like.

The memory controller 342 uses the command from the one-chip microcomputer 330 to receive the image processing board 31.
4 to output image data directly to the printer or to the image memory board 343, main scanning from the image processing board 314 or the printer 300,
Switching between the sub-scanning synchronization signal, the gate signal, and the clock signal is performed.

Further, the memory controller 342 can generate a main scanning / sub scanning synchronizing signal (LSYNC), a gate signal (FGATE), and a clock signal so that the output from the image memory board 343 can be controlled. Further, the memory controller 342 controls the character generator 344.

The character generator 344 has character ROM and graphic pattern data in the internal ROM and can output the data. The output timing of this character generator 344 is instructed by the memory controller 342, and its output is the OR circuit 345.
And is output to the printer 300.

The OR circuit 345 is the memory controller 3
The image data output from 42 and the pattern data output from the character generator 344 can be combined. The image memory board 343 has a memory for the maximum original reading size for two pages as a standard.

Also, this image memory board 343 has 1
A memory can be added for incrementing the number of bits per dot of multi-value dot output and for recovery when a printer jam occurs.

Next, the operation modes relating to the present invention will be described. As described above, the operation mode of MFDS is
It is roughly divided into two modes, one is a book original reading mode for performing page turning reading operation of a book original, and the other is a sheet original reading mode (ADF mode and pressure plate mode) for reading a sheet original. (FIG. 38).

In the present invention, of the book document reading modes, the ID card recognition mode and the bar code recognition mode can be set so that the copyright usage fee can be managed (FIG. 36).

Here, the ON / OFF setting of each mode is as follows.
In order to prevent the user from easily changing the setting, the encryption key is input from the operation display board 313 or the program RO in which each mode is incorporated from the beginning is set.
You may make it perform using M. The other subdivided modes are as described above with reference to FIG.

Next, switching of individual modes by key input from the operation unit and automatic mode switching by sensor input will be described. In FIG. 60, when the main power source of the MFDS is turned on, the main control board 310, the operation display board 313, the turning unit drive control board 312, and the turning conveyance belt drive control board 3 shown in FIG.
11. The image processing boards 314 and 317 are reset and initialization is performed.

In this initial setting, the automatic selection mode shown in FIG. 35 is set. In this automatic selection mode, the mode is automatically selected by each sensor input. After that, the connection of the output device such as the printer 300 is checked, and the mode applicable to the connecting device such as the printer is displayed, while the key inputs of the number of copies, the magnification, the number of pages to be turned, and the mode are accepted.

If the automatic selection mode is turned off, the mode selection can be set by key input from the operation display board 313. That is, when a mode is designated by the mode selection key of the operation display board 313, this operation display board 3
A mode selection code is transmitted by serial communication from 13, and the mode selection flag is set accordingly.

By this mode selection flag check, branching to each mode (subroutine call) is performed. On the other hand, when the automatic selection mode is turned on, the mode is branched as shown below according to each sensor input and setting condition when a book document or a sheet document is set.

When the sheet original is placed on the sheet original tray 94, the sheet original sensor 25 is turned on. Further, the transport section 19 is opened to open the central position reference determining section 24 of the document table 18.
When the book document is set in the open state, the book document sensor 27 is turned on. These two sensors 2
5, 27, the mode is switched as shown in FIG.

That is, the book original sensor 27 is turned off,
When the sheet document sensor 25 is on and the number of the set number is one, the sheet document through mode (ADF mode) is set. When the number of the set number is two or more, the sheet document scan mode (ADF mode) is set. , 27 are both off, the sheet document manual opening / closing mode (press plate mode) is switched to.

If the book original sensor 27 is on and the sheet original sensor 25 is off, the book original reading mode is entered. If both sensors 25 and 27 are on, the above processing 1 is executed to generate a warning buzzer. After displaying an error message to call the user's attention, the mode transits to the book document reading mode.

Here, while the book document reading mode is a mode in which copyright usage can be managed, the sheet document reading mode (ADF mode and pressure plate mode) is designed so that a normal copying operation can be performed.

That is, in the case of the book original mode and the pressure plate mode only (without ADF mode), the central positioning unit 2
The mode is determined by looking at the state of the book document sensor 27 of (4), and (1) when the book document sensor 27 is on and in the book document mode, the image of the image reading sensor unit 9 for reading the image of the book document is read. The memory controller 3 which outputs the number of reading scans or image information read by the reading sensor unit 9.
When the book document sensor 27 is off and in the pressure plate mode, the number of times the image information is output by the image reading sensor unit 9 is read by the counting unit 42.
Alternatively, the counting of the number of times the image information is output by the memory controller 342 is not executed.

After entering each mode subroutine, if the reading start key is not pressed,
It is designed to return without executing any processing.

The mode operation of each is as described above.

Next, the book document reading mode relating to the present invention will be described with reference to the flow charts of FIGS. 61 to 63. 61 to 63, when the book document reading mode is entered, the on / off of the belt tension sensor 34 is checked.

This is to detect a level at which the book reading document placed is too thick and the page-turning reading unit 1 cannot scan the document surface. When the belt tension sensor 34 is turned on, the abnormal process 2 is executed, the warning buzzer is turned on and "the book is too thick" so that the user will not forcefully close the transport unit 19 and damage the device. Is displayed.

If the thickness of the book document is equal to or less than the adaptive level, the user closes the transport unit 19 and turns on the transport unit lock sensor 31. At this time, if the transport unit 19 remains open, the abnormal process 3 is executed, the warning buzzer is turned on, and the error message "Please close the transport unit" is displayed.

When the transport unit 19 is closed in this manner, the on / off of the book size upper limit detection sensor 33 is checked, and when this sensor is on, the size of the book exceeds the reading area. Abnormality processing 4 is executed, the warning buzzer is turned on, and the error message "The size of the book is too large" is displayed.

Then, when the book size upper limit detection sensor 33 is off, it is determined that the number of copies, the magnification, and the number of pages to be turned have already been set, and further it is determined that the ID card recognition mode is set. Then, the subroutine is called.

The ID card recognition mode is operated as shown in the flowchart of FIG. When this ID card recognition mode is executed, as shown in FIG. 64, first, whether or not the ID card reading device 340 is connected is determined by a break signal exchange via the serial interface 338 (FIG. 59). Checked in.

Here, if the ID card reader 340 is not connected, a command is transmitted via the serial interface 337 to the operation display board 313 to display an instruction of the connection method, and the NG flag is set. Then, the process returns to the book document reading mode.

On the other hand, when the ID card reader 340 is connected, a command is transmitted to the operation display board 313 to display the operation method of the ID card reader 340.

Next, commands are exchanged on the serial communication as to whether or not the individual code is read from the ID card. As a result, if the individual code has not been read yet, the NG flag is set and the process returns. If it is determined that the individual code is being read, then it is determined whether the ID code permits copying of the book document. Then, if the ID code does not permit copying of the book original, a command is transmitted to the operation display board 313 so as to display an error message such as "copying of the book original is not allowed".

On the other hand, when the ID code permits the book original copy, the address of the counter on the external RAM 332 set for each ID code is selected,
Return to the branch source routine. This external RAM 33
The counter above 2 has a function of counting the number of copies of a book document for each ID code.

After the return of the ID card recognition mode described above is completed, it is determined whether the NG flag is set or reset.
Here, if the NG flag is set, NG
After resetting the flag, the book document reading mode is returned and the process ends.

On the other hand, if the NG flag is not set, it is judged whether the barcode recognition mode is set or not, and the subroutine is called. At this time, if it is not the barcode recognition mode, the process proceeds to the next mode.

[Explanation Corresponding to Claim 1] FIG. 65 shows a flowchart of the above bar code recognition mode.

In this subroutine, first, the connection check of the bar code reading device 341 is performed.

If the bar code reading device 341 is not connected, a command for displaying an error is transmitted to the operation display board 313, the NG flag is set, and the process returns.

On the other hand, if there is no abnormality, the LED inside the bar code scanner is turned on, and the bar code attached or printed on the book original is read by the CCD inside the bar code scanner.

By setting the reading position of this bar code scanner near the book manuscript set reference position, the bar code pattern of the back cover portion of the book manuscript as shown in FIG. 66 is not affected by the size of the book manuscript. 34
1c can be read. Therefore, in the embodiment of the present invention, as shown in FIG. 67 and FIG.
The bar code scanner 341a of the bar code reading device 341 is attached to the book document set reference position side of the center reference positioning portion 24 of the document table 18 that supports the center binding portion (spine cover portion) of No. 2.

A bar code scanner 34 other than this embodiment.
The mounting position of 1a may be in the vicinity of the original setting reference position of the front cover or the back cover of the book original, which is within the minimum readable original size of the book original. Note that FIG.
A page-turning reading unit 1 shown in FIG. 8 includes a page storage portion 7 for storing a document page that is turned over by a turning roller 2 and a reading sensor unit 9 for taking the document page into the world. In the example shown in FIG.

The data of the bar code pattern 341c read by the bar code scanner 341a is converted into the bar code decoder 34 in the bar code reader 341.
1b, converted into ASCII code, and sent to the one-chip microcomputer 330 via the serial interface 339 of the main control board 310.

If the bar code pattern 341c cannot be read, an error message "Bar code pattern cannot be read" is displayed, the NG flag is set, and the process returns. When the barcode pattern 341c is read, it is determined whether or not copying of this barcode pattern is permitted. If copying is not permitted, an error message "This book document (bar code pattern is not permitted to copy)" is displayed on the operation display board 313.

On the other hand, if copying is permitted, the address value of the counter on the external RAM 332 set for each read code is selected and the process returns. The counter on the external RAM 332 is a counter defined for each bar code pattern, that is, a counter weighted by, for example, publisher, author, or price.

After returning to the book original reading mode, the NG flag is judged. If the NG flag is set, this NG flag is reset and the process returns. If the NG flag is reset, the next automatic book size recognition mode is entered.

In case of the automatic book size recognition mode,
If the prescan flag is set, otherwise, the book manuscript size input mode is entered and the operation display board 313
More key input is performed to set the size of the book original and determine its reading area.

Here, when the reading start key is pressed, the above-described transport unit locking mechanism operates.
This is to prevent the user from accidentally opening the transport unit 19 and damaging the document page during the page turning operation of the book document. If the prescan flag is set after the operation of the transport unit locking mechanism,
Perform the prescan operation, and skip if the prescan flag is not set.

After the prescan operation or after the skip, the process waits until the connected device (printer 300) is ready. Then, when the preparation is completed, the reading operation of the book original is started. After the end of this reading operation, the ID code / bar code count operation processing subroutine is called.

In this ID code / bar code count operation processing subroutine, as shown in FIG.
The state of the center binding unit sensor 346 is determined. Figure 7
As shown in 0, the central binding unit 347 is used when copying a stapled document or the like having no copyright.

That is, this central binding unit 347
Is detachably attached to the apparatus main body so that the stapled document can be set in the central reference positioning portion 24 of the document table 18 in a clipped (clamped) state. Then, the central binding unit 347 is used for the document table 18
When set in the central reference positioning section 24, the central binding unit sensor 346 is turned on by the detection piece 347a formed at the end thereof, and it is determined that the original set on the original table 18 is not a book original. To be done.

When the central binding unit sensor 346 is on, the counting operation described above is not necessary.
Immediately returned. Here, when the central binding unit sensor 346 is off, the counter value selected for each code in the ID card recognition processing (FIG. 64) and the bar code recognition processing (FIG. 65) that were called previously is loaded and counted up, Further, the original address value is stored. External RAM 332 used at this time
Is backed up by a battery backup battery 334 even when the power is off.

The count-up at this time is counted so as to correspond to the number of read pages of the book document. In other words, if you read the book manuscript every two pages,
Counted up by 2 each.

The central binding unit sensor 34 described above is used.
6 uses a light transmission type sensor, for example, a unique bar code pattern is attached or printed on the back side of the central binding unit 347, and the bar code pattern is used for both this fraud prevention and cost reduction. Scanner 34
It may be distinguished from a book original by being read by 1a.

In this way, it is possible to judge how many pages have been copied for each book document based on the count value. Then, the above-mentioned reading operation is repeated for a preset number of sheets, the page turning operation is executed, and this operation is repeated until the turning reading operation of the final page is completed. As a result, after the page-turning reading operation of the last page of the book original is executed, the book original reading mode is returned and the operation ends.

On the other hand, the data counted by each ID code and each bar code described above can be output to the display section at any time by keying in the operation section. When the printer 300 is connected to the MFDS, the one-chip microcomputer 330 of the main control board 310 calls the counter value stored in the external RAM 332 for each code by key input from the operation display board 313. Memory controller 34
The character generator 344 controlled by the synchronization signal generated by 2 can output the count data together with the image output such as the list and the graph.

Thus, for example, the copyright fee can be accurately collected for each individual or group based on the ID code counter value. In addition, the operation display board 31
It is also possible to calculate the total amount of money at the end of copying by setting the price for copying one page in advance by key input from 3, and by the counter value.

Furthermore, if the price per page of the manuscript is entered in advance by the value counted for each book manuscript by the bar code pattern 341c, the payment amount can be listed by the author or publisher of the manuscript by period. Can be output to the printer 300.

These outputs can be output at any time by key input on the operation display board, but may be output periodically by the timer function of the microcomputer in the main control board.
You can save the time and effort of key input by automatically outputting weekly or monthly.

When copy paper is jammed on the printer 300 side connected to the MFDS, the main control board 3 of the MFDS is fed from the printer 300 side.
The jam occurrence code is transmitted to 10 by serial communication.

As a result, the MFDS side performs the printer jam recovery operation.

As part of this recovery operation, due to the transmission timing of the previous jam occurrence code, as shown in FIG. 63 and FIG.
If the ID code / bar code count operation has been completed, a minus count is performed. Also, here, ID
If the code / barcode count operation has not been performed, the count value at this time is held as it is.

On the other hand, in this embodiment, the example in which the count operation processing subroutine for each ID code / bar code is incorporated in the book original reading mode routine has been shown. However, the discharge OK code (transfer sheet) transmitted from the printer 300 is shown. When the code is output from the printer 300 to the MFDS) is received, the above subroutine call may be incorporated.

As described above, when the discharge OK code (code output to the MFDS when the transfer paper is discharged from the printer 300) transmitted from the printer 300 is received, the above subroutine call is executed. Incorporation into the card eliminates the need for a negative count when jamming.

By the way, the above embodiment is an example in which the image output is processed in real time. For example, when the processing speed of the printer 300 is high, or in order to speed up the repeat copying and protect the original, An example of a case in which the image data is stored in the memory and then the image data is output from the memory at a suitable time will be described below.

As described above, for example, in FIG.
When the read image of the book original is temporarily stored in the image memory board 343 via the memory controller 342 and the stored image data is sequentially output to the printer 300, the MFDS one-chip microcomputer 330 sends the FGATE to the memory controller 342. By incorporating the ID code / bar code count operation subroutine every time an output is requested, the previous count operation can be performed even during memory retention.

[Explanation Corresponding to Claim 7] Further, in the above-mentioned embodiment, the permission / non-permission of copying is judged by reading the bar code pattern 341c of the spine of the book original. It is also possible to determine the permission / non-permission of copying of the book original by reading a stamp, a seal, a sticker, or the like, which is pasted or pressed on the page, and recognizing the pattern.

As described above, the image memory board 343 is provided with means for determining permission / non-permission of copying of the book original by reading the stamp, seal, seal, etc. of the book original and recognizing the pattern. Read data such as stamps, seals, stickers, etc. of book originals is stored, and it is determined by pattern matching whether or not there is a copy permission mark at a predetermined position (predetermined address) on the memory, and copy permission or counting operation from the memory is performed. Decide whether or not to do it.

Here, when the memory board 343 is not used, the above-described determination may be performed in the prescan to determine whether to permit or prohibit the reading operation of the book document.

[Explanation Corresponding to Claim 8] By the way, in this MFDS, the read image information is read by the printer 300.
When outputting to, the character generator 344 can combine and output additional information such as characters and marks (read ID code or bar code pattern) together with the read image data of the book original by the OR circuit 345. This makes it clear whether or not a copy is made from a copyrighted book original, and it is possible to prevent further infringement of the copyright due to erroneous copying.

[0433] For example, when a copy of a book manuscript with copyright is directly copied, this system enables collection of the copyright fee. However, when a copy of this book manuscript is copied as the original, the copyright It becomes impossible to count to calculate the fee.

Therefore, when copying a copyrighted original document, the read image data and the copy prohibition mark or code are combined and output as the copy image in advance to output such a copy of the book document as the original. It is possible to collect copyright fees even when copying.

Further, in this embodiment, the ID card recognition means determines whether or not the reading of the book original is permitted. However, for example, the reading is performed by a password input from the operation unit or a key input such as a personal identification number. The permission / non-permission of the operation may be determined.

Further, by connecting a prepaid card reader to this MFDS when permitting / disapproving the reading of the book original or collecting the copyright fee, the prepaid prepaid copyright fee is paid during the reading processing of the book original. The copyright fee may be collected by lowering the points of the card.

[0437]

According to the present invention, an image reading apparatus capable of coping with a copyright problem by allowing only a specific book original permitted or an image to be read (copied) by a specific user. Can be provided.
