Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing and copying machine that extracts necessary portions of a plurality of originals and edits them on one sheet (transfer sheet).

2. Description of the Related Art Various copying machines having a so-called analog image editing function of analogly extracting necessary portions of a plurality of originals and editing or synthesizing them on one sheet (transfer sheet) have been known.

Conventionally, in this type of copying machine, a first original in which a portion into which a second original should be inserted is perforated and the second original is superposed and copied as one original, or the first original is copied.
A sheet in which a copy of an original is temporarily stored in a sheet storage unit in the machine, and when the second original is copied, the sheet is retransmitted to a transfer position, and a necessary portion of the second original is copied on the same surface as the copy surface of the first original. Etc. are known.

In the latter copying machine, the exposure relative position adjusting means and the erasing means are used to align the respective originals.

As described above, the concept of image editing in the composite copying apparatus has been publicly known, but none of them specifically discloses the technique or various functions related to image editing for improving operability.

Further, conventionally, there has been a drawback in that when an image area is set, a large number of switches are required and the cost becomes expensive.

Purpose The present invention was made on the basis of such a background of the conventional example, and an object of the present invention is to improve the function of image editing and the operability of the image editing area input section. When the image area of is displayed, the document number and the display color are displayed in association with each other to facilitate editing.

Configuration The configuration of the present invention will be described below with reference to the drawings. Figure 1,
The function of the copying machine, which is the premise of the present invention, will be described with reference to FIGS. 2 and 3, and then the present invention will be described with reference to FIGS.

In FIG. 1, the first document set at a predetermined position by the document replacement device 1 is illuminated by a known illumination exposure optical device 8 including a light source 2, mirrors 3 to 6 and a lens 7, and an image is formed on a photoconductor 9. Exposed. The photoconductor 9 is a charger 10.
The uniformly charged surface is exposed by the illumination and exposure optical device 8 to form an electrostatic latent image. The electrostatic latent image is developed and visualized by the developing device 11 while the photosensitive member 9, for example, the photosensitive drum is moving.

The visible image of the photoconductor 9 is transferred at a transfer position to a transfer paper 14 as a copy paper detected by the paper feed units 12 and 13.
A transfer drum 15 is used in FIG. 1 as a means for transporting the transfer paper 14 to the transfer position.

After the transfer, the photoconductor 9 is destaticized, cleaned by the cleaning device 16, and the process from charging is repeated.

The transfer paper 14 on which the image of the first original is transferred is sent to the storage device. In FIG. 1, the transfer drum 15 is also used as a storage device. Therefore, the transfer paper 14 delivered from the paper supply units 12 and 13 is first clamped by the clamp 17 provided on the transfer drum 15.
Clamped by. The transfer paper 14 is clamped by the transfer drum 15 to make one rotation, and the transfer paper 14 is rotated from the photosensitive member 9 to the first position.
After the image of the original is transferred, it is temporarily stored in a state of being fixed to the transfer drum 15 at a position where it does not contact the photoconductor 9.

A method of changing the distance between the transfer drum 15 and the photoconductor 9 so as to keep the photoconductor 9 in a non-contact state during storage, or a recess is provided in a portion of the transfer drum 15 where there is no transfer paper, and Various methods such as a method of facing each other can be used.

In the above process, the image of the first original is transferred to the transfer paper, and the original replacement device 1 is provided while the transfer paper is stored by the storage device.
At, the first original is taken out and the second original is set at a predetermined position. Thereafter, the photoconductor 9 is charged and exposed and developed in the same steps as in the case of the first document, and the image of the second document formed on the photoconductor 9 is transferred onto the transfer paper, for example, the transfer drum 15 supplied from the storage device. When it is rotated again, it is transferred onto the transfer paper 14 sent to the transfer position on the same surface as the image of the first original. In this manner, when the images of a predetermined number of originals from the third original onward are transferred and synthesized on the same surface of one transfer paper, the transfer paper 1
The clamp 4 is released from the clamp, is fixed by the fixing device 18, and is discharged to the paper discharge tray 19.

The document replacing device 1 is simply a document placing glass 20 of a copying machine.
It is also possible to use a structure in which the documents are manually replaced on the upper part, or a semi-automatic document handling device or a fully automatic document handling device that has a feed belt 21 and feeds and sets the documents to be inserted by hand to a predetermined position can be used. .

The transfer drum 15 is also used in FIGS. 1 and 2 as a transfer paper storage device from the transfer of the image of the first document to the transfer of the image of the second document. Therefore, when the image of the second original is transferred, when the deviation between the composite position of the first original and the information position of the second original in the transfer paper feed direction is adjusted by the transfer paper feed timing, the rotation of the photoconductor 9 The photoconductor 9 is rotated with a desired timing deviation. At this time, in order to avoid slippage between the photoconductor 9 and the transfer drum 15, the transfer drum 15 is stopped at the stop position.
The portion facing the photoconductor is formed as a recess to avoid direct contact, or when the transfer drum 15 stops the photoconductor 9 when stopped.
It can be a structure that moves away from.

The storage device may be provided separately instead of being shared by the transfer drum 15. For example, as shown in FIG. 2, the transfer paper is fed from the paper feed units 12 and 13 to the transfer position by the photoconductor 9 by the transfer roller 22 and the guides 23, 24 and 25 or the transfer paper conveying means 27 having the feed belt 26, and the transfer paper is publicly known. The transfer tray 3 is fixed by the fixing device 18 after the transfer is performed by the above means, and then the storage tray 3 is passed through the storage path 29 switchably provided by the first gate 28 to the path to the discharge tray 19.
Send to 0. When the sheet is fed to the storage tray 30, the tip is always inverted so that the tip is fed, and in the example of the figure, the copy surface is fed downward and stored.

After one or a predetermined number of copy sheets of the first original are stored in the storage tray 30, the transfer of the second original is performed. In the figure, the document replacement device 1, the illumination exposure device 8,
The relevant parts of the photoconductor 9 are the same as those in FIG.

When copying the second original, the rotation of the registration roller in the storage tray 30 or the rotation of the registration roller when it is stopped by the registration roller provided in advance in the storage tray 30 in synchronization with the exposure timing and provided in the middle of the transfer sheet conveying means 27. The driving is performed under the timing adjustment according to the positional deviation calculated by the composite position signal and the information position signal, and the composite position of the transfer paper carrying the image of the first original reaches the transfer position of the photoconductor 9. At this time, the adjustment is performed so that the image of the information of the second original formed on the photoconductor 9 is exactly at the transfer position. The transfer paper is stored in the storage tray 30 in the number corresponding to the original to be combined, and is repeatedly sent to the transfer position of the photoconductor 9 repeatedly.

When the composite copying of the final document is completed, the transfer sheet is discharged to the discharge tray 19 by switching the first gate 28.

In FIG. 2, another second gate 31 is provided from the fixing device 18 to the first gate 28, and the transfer paper is reversed to the case where the transfer paper is sent to the storage tray 30 through the first gate 28. That is, without turning over after passing through the fixing device,
In the figure, it is possible to provide a switching path 32 that feeds to the storage tray with the copied surface facing upward and the front end being the rear end. When the transfer paper is sent to the storage tray 30 through the switching path 32 by the switching of the second gate, the surface of the transfer paper, which is opposite to the surface opposite to the previous one, comes into contact with the photoconductor and is transferred. That is, double-sided copying becomes possible.

By providing the two gates 28 and 31 and enabling the transfer method of the transfer to the storage tray to be switched in two ways, it is possible to perform composite copying and double-sided copying, and further double-sided composite copying. That is, the above-mentioned synthetic copying operation is performed on one side, and then the second storage tray 30
Double-sided composite copying is possible by sending from the gate 31 through the switching path 32 and then again performing the composite copying operation on the back side.

Incidentally, reference numeral 33 in FIG. 3 is a sorter, which can be connected to a copying machine in place of the discharge tray 19 in FIG.

Next, FIG. 4 shows the operation section of the copying machine according to the present invention, and the operation mechanism will be described with reference to this figure.

Although it is not normally visible at 0, when it is lit, the display as shown in the figure appears.

When copying, it is preferable to operate the keys on the left side of the operation unit, and the functions will be described from the keys on the left side.

The left blank and right blank keys 45 and 46 are keys for adjusting the binding margin, and the binding margin is 15 on the left side of the copied transfer paper.
mm If you want to make, press the left blank key 45,
When 15 is entered with the 10 key 34, the 7-segment display on the upper part of the display section 49 lights up as "15". This may be blinking, and when the left blank key 45 is released, "15" disappears and "1"
Return to. The same applies to the right blank key 46.

The composite copy key 48 is used when it is desired to copy the first document and the second document in an overlapping manner.

The reverse discharge key 47 is used when the transfer paper after copying is to be turned upside down and output to the discharge tray 19, and when the first original is copied, the transfer paper discharged is the lower one. Since it is a copy of the eyes, if you turn it upside down, you can turn over a large number of ejected transfer papers, and page alignment will be done from the first sheet.

The stack key 43 and the sort key 44 are publicly known ones without any explanation.

The double-sided copy key 42 for a double-sided original or a single-sided original is used when a double-sided copy is desired, and there are a case where a double-sided original is copied and a case where a single-sided original is desired to be double-sided.

The paper feed selection key 40 is used to select the paper feed trays 12 and 13, and the display unit 49 displays A4 for the first paper feed tray.
B4 and A3 are set in the second and third paper feed trays, respectively, and when the first tray is selected, the A4 display section is surrounded by a frame. When the user wants to select the second stage, pressing the paper feed selection key 40 moves the frame to the second stage and the second stage is selected.

There are an enlargement key and a reduction key (magnification setting key 41) for setting the magnification.
Percentage is displayed on the display unit 49. Then, for example, when "71%" is displayed, "A3 → A4" is also displayed to inform that the magnification is to reduce A3 to A4.

The ten keys 34 from 1 to 9,0 are used to set the number of sheets, and are displayed in the seven segments above the display unit 49.
The lower 7-segment display is for displaying the number of copies. Further, as described above, it is also used when the left and right blank keys 45 and 46 for adjusting the binding margin are pressed and the binding margin width is set by the 10 key 34. Although there is an enlargement / reduction key in the figure, it is also possible to use this key as one magnification key and input a desired% with the 10 key 34 while pressing this magnification key.

The interrupt key 35 is used when an urgent copy is required during copying. When the interrupt key 35 is pressed, the copy is interrupted, and when the emergency copy is performed, the interrupt key 35 is pressed again.
You can return to the previous mode and resume copying.

The description of the clear / stop key 36, the density adjustment key 38, and the print key 37 will be omitted.

The standard mode setting key 39 is used to change to a preset mode by pressing the key, for example, A4
If you set a magnification of 100% (actual size) in size, if the mode used by the previous person is A3 size 71% reduction ratio and double-sided copy sort mode, you do not have to cancel these. Therefore, by simply pressing the standard mode setting key 39, the magnification can be changed to 100% in A4 size.

The above is the description of the keys. In the case of the figure, the left blank, right blank keys 45, 46, the composite copy key 48, and the reverse discharge key 47 are not the keys that are always used, and therefore the lid is covered. .

Next, the display functions of the display units 49 and 50 which have not been described will be described.

The display 4901 is turned on when the original and the transfer paper do not match, and of course, the determination is made including the magnification.

The display 4902 is lit when there is no paper in the paper feed tray.

The display 4903 is lit up when the back side is copied during double-sided copying.

It lights up when the stack or sort key is pressed, warning that it will not mix with the previously copied transfer paper.

A display 4904 is a display for warning that the manuscript has been forgotten.

The display 4905 lights up when the interrupt key 35 is pressed.

The display 5001 lights up during warm-up.

The display 5002 lights up when the warm-up is completed and the copy key 37 is pressed to start copying.

The display 5003 is displayed by a numeral when there is an abnormality in the machine. At this time, the display 5004 is also turned on and a serviceman call is made. This number makes it possible to identify the abnormal part,
It has the meaning of self-diagnosis. It can also be used to display the time in minutes while warming up.

The display 5005 is lit when the door is open. When the door on the sorter side is open, the displays 5005, 5006, 5007 are lit.

The indications 5008 and 5009 are lit when jamming, and the indications 5009 and 5006 are lit in case of jam in the sorter.

The display 5010 lights up when the key counter is not set.

The display 5011 is lit when the toner is insufficient.

The operation part of the ADF is shown in FIG. 5, which will be briefly described.

In the operation panel shown in FIG. 2B, the ADF key 51 is used to automatically feed a document, and the SADF key 52 is used to manually insert a document, both of which are well known.

The size unifying key 53 is a mode in which the original size is detected and the magnification is automatically set so as to match the transfer paper size in the selected paper feed tray. It is used when you want to unify.

An automatic paper feed selection (APS) key 54 is used to detect the size of a document and automatically select the transfer paper in the paper feed tray so that the set magnification is obtained.

4b and 65 partially overlap but 64a and 64
This is a case where it is necessary to copy either of them depending on the contents copied to b (when no priority order is set).

The examples on the CRT screen are shown in FIGS. 6 (a) to 6 (g). C
If RT is a color type, for example, if 64 is green, 65 is yellow, and 66 is red in FIG.
When the CRT is not a color type, 64 can be distinguished by a solid line, 65 by a broken line, and 66 by a dot-dash line.

When there are priorities as shown in Figures (e) and (f), it is also possible to predetermine red, yellow, blue, etc., or the solid line, broken line, dash-dotted line, etc. from the highest priority. is there.

The numbers in 64, 65 and 66 shown in FIG.

For a color CRT, the first document is red, the second document is yellow, and the third document is blue.
The numbers in 5, 66 are unnecessary.

Next, the operation unit for image editing is shown in the block diagram of FIG.

The pressure-sensitive sheet 67 that uses a pressure-sensitive sheet for detecting the position of the original has signal lines for inputting and outputting each matrix signal on the x-axis and the y-axis.
The position information can be input by the scan signal from 8.

The I / θ controller 68 is connected to a host μcpu described later via a data bus.

The original editing area is detected by the matrix information of the scan timing signal and the scan return signal of the pressed pressure sensitive sheet 67.

The key group 69 connected to the area operation unit includes an edit start key, an edit end key, a priority key, an area shift key (left, right, up, down), a zoom key (up, down),
It is composed of color designation keys (black, red, blue).

The key press is determined by the scan signal for detecting the key code and the scan signal when the key is pressed by the I / θ controller 6
It depends on the matrix signal of the return signal returning to 8.

Explaining the operation keys, the edit start key is a key for notifying the start of editing of a document, and the position information of the pressure sensitive sheet 67 is canceled unless this key is pressed.

The edit end key is a key for notifying the end of the editing of the document, and when the key is pressed, the designation of the area is completed. If the edit end key is not pressed, it is possible to arbitrarily specify a plurality of areas in the document.

The priority key is pressed when a document is desired to be secured by giving priority to the overlap of regions when the regions of a plurality of documents are designated.

When this key is pressed before, after, or during the area designation, the priority flag is set in the RAM that stores the number of documents.

The area shift key shifts the left, right, up, and down positions without changing the length of the frame of the specified area.

The data in the y-axis direction of the data contents of the area RAM MAP shown in FIG. 8 is changed, and the position data updated when the shift key is released is stored.

With the 691 and 692 keys, the y-axis position data of RAM is updated.

With the 693 and 694 keys, the data of the x-axis position of RAM is updated.

The zoom key is a key to be pressed when changing the size of the image in the area frame, and can be instructed in the enlargement / reduction direction steplessly.

The color designation key is a key to be pressed when multicoloring is performed on copy paper.

The pressure sensitive sheet key determines the position information of the editing area frame and is effective while the editing end key after the editing start key is pressed, and is determined by the matrix signal of the x axis y axis scan signal and the scan return signal.

The scan timing T _X1 and the return signal T _y1 port signal is used as the positional information of x ₁ y ₁ to scan the entire region of T _xn T _yn to determine the position.

FIG. 9 is a view showing a pressure sensitive sheet showing the x-axis and the y-axis, and FIG. 10 is a view showing a state in which a transfer sheet is placed on the pressure-sensitive sheet 67. The area surrounded by the four corners inside the transfer paper is an image editing area.

11 (a) and 11 (b) are diagrams showing the area shift state, and FIG. 12 is a RAM map at that time. In FIG. 7, 70 and 71 are drivers, and 72 is a comparator.

Next, the optical illumination unit will be described.

As one element for image editing, there are conversion of image size and image position on the copy screen.

In the analog image editing / copying apparatus to which the present application belongs,
This is achieved by an optical image projection device (optical system).

In the copying apparatus shown in FIG. 1, the document placed on the document mounting glass 20 is illuminated by the light source 2, and the image of the document is projected in a slit shape on the photoconductor 9 by the mirror groups 3 to 6 and the lens 7. It

Further, the image of the original is continuously projected onto the photoconductor 9 by the first mirror 3 (speed υ) and the second mirror 4 which are integrated with the light source 2 relatively scanning the original.

Variable-magnification projection is used to convert the image size.

i) The magnification conversion in the mirror scanning direction is determined by the relative relationship between the surface speed υ _O of the photoconductor 9 and the first mirror scanning speed υ. If the magnification is m (This is not the case in a full-exposure copying machine such as flash exposure.) Ii) Magnification conversion in the direction perpendicular to the above i) (axial direction of the photosensitive drum) is performed by so-called zooming.

In the example of FIG. 1, a fixed focus lens is used. Move the lens 7 in the direction of the optical path by an amount (Δa) that matches the magnification m, and set the mirrors 5, 6
It is achieved by displacing and correcting the total path by Δl. If the focal length of the lens is f When using a zoom lens, correction of the total path can be omitted.

The displacement of the image position is achieved by the following means.

i) The position change in the mirror scanning direction is achieved by changing the relative positional relationship between the image and the transfer paper, that is, the contact timing of the transfer paper 10 to the photoconductor when the toner visible image formed on the photoconductor is transferred. (The timing relationship between the photoconductor and the transfer paper may be kept constant and the mirror scanning start timing may be changed.) Ii) Image position conversion in the direction orthogonal to the above i) is image projection by moving the lens in the direction orthogonal to the optical path. Achieved by position conversion.

FIG. 13 is a plan view of the lens optical path.

In FIG. 13, when the information in the partial range a of the original range A is exposed, the image is usually formed in the partial range b of the range B of the photoconductor. The photoconductor corresponds to copy paper or transfer paper. Now set the lens 7 to 1/2 in the direction orthogonal to the optical axis.
When it is moved by a distance, it moves from the partial area b on the photoconductor to the partial area b ′ moved by the distance 1 in the moving direction of the lens 4. That is, by selecting the amount of movement of the lens in the direction orthogonal to the optical path, it is possible to arbitrarily select the image forming position on the photoconductor, in the first place, on the copy paper in the direction orthogonal to the movement direction of the copy paper.

If this is also used together with magnification conversion by moving the lens 7 along the optical axis, it is possible to perform variable magnification copying for changing copying magnification and composite copying at the same time. The amount of movement of the lens in the direction orthogonal to the optical axis is set by calculating the deviation of the information position from the designated copy position by the control device and controlling the lens moving device by the signal.

As a structure for moving the lens, for example, FIG. 14 and FIG.
As shown in FIG. 5, the lens base 73 for fixing the lens 7 is supported by the lens bracket 74, and
4 is screwed to a screw shaft 76 rotatably supported by an optical system frame 75, and the screw shaft 76 is reversibly rotated by a motor 77 directly or by a motor 77 via a belt or the like, so that the lens 7 is made to be an optical axis. Structures that move in orthogonal directions can be utilized. By guiding the movement of the lens bracket 74 by the guide bar 78 fixed to the optical system frame 75, the lens can be smoothly reciprocated without tilting. If the optical system frame 75 itself is screwed to a screw shaft or the like to be movable in the optical axis direction in the same manner as in FIGS. 14 and 15, the magnification can be changed.

In addition to the method of controlling the feed timing of the copy paper and the control of the lens movement for the image position conversion, the original can be moved together with the original placing glass in one direction or two directions orthogonal to each other, and the original setting position is adjusted The method to do is also available.

Reference numerals 620 to 622 are resistance photo interrupters which detect a notch portion of a circular bun having a radial notch portion which rotates in synchronism with the photosensitive drum and emit a clock pulse. The timing of the copying machine is controlled by this pulse number.

FIGS. 19 to 21 are for explaining the purpose of the present invention in more detail in addition to FIGS. 6 (a) to 6 (g).

In the drawings such as 1-a in the drawings, 1 represents the original NO, and a represents the input order NO of a plurality of areas input from the original.

FIG. 19 shows an example that is most effective when the document NO and the display color are associated. (a) shows a state in which two areas 1-a and 1-b are input from the first original,
(b) shows a state in which 2-a and 2-b are input from the second document. 1-a and 1-b are, for example, red, 2-
a and 2-b are displayed in blue, for example. (c) is
It shows the case where they are displayed simultaneously as they are,
Since the display color for each document is the same, it is easy to take an image when the entire layout is changed. (d) is the layout after editing, and the areas 2-a and 2-b input from the second original are 1-
The arrangement is such that it is inserted between a and 1-b.

FIG. 20 shows an example that is most effective when a plurality of areas are input from the same document and the input order and the display color are made to correspond. (a) shows a state in which one area 1-a is input from the first manuscript, and for example, the area is displayed in red or the like in the text portion of the guide. (b) shows a state in which a plurality of areas 2-a to 2-d are input from the second manuscript. For example, when an address book is input, reds and oranges are sequentially input from 2-a to 2-d. , Yellow, yellow-green, etc. (c) and (d) are the layouts edited from (a) and (b). The second original part is sequentially replaced, and the combination of each color is replaced by the upper color in order and the whole is changed. The image of is easy to grasp. Alternatively, the color display according to the input order from the same original document is effective for the editing of the nth input area comrades of each original document.

FIG. 21 shows an example in which the priority and the display color are associated so that the effect is most effective when the priority exists in the area to be copied. For example, 1-a is a sentence input from the first manuscript, and 2-a and 2-b are reference diagrams for the sentence input from the second manuscript. That is, since the reference diagram is placed to facilitate the understanding of the text, it corresponds to the case where a part of the reference drawing is hidden in the text and need not be copied. At this time, 1-a is instructed to have priority over 2-a and 2-b by the priority key in FIG. D-3, and is different from 2-a and 2-b for indicating the priority, for example. Displayed in red, etc. However, at this time, 2-a, 2-b
Is the normal display color.

Effect The present invention is as described above. According to the present invention, since the original NO and the display color are displayed in association with each other, even if there are a plurality of inputs from the same original, the area is the area input from the same original. You can tell at a glance. Further, if it is known that the areas are input from the same original, there is an effect that the images of the originals can be easily floated at the time of editing and the editing can be performed smoothly.
