[Problem to be solved by the invention]

However, in the above-mentioned device, multiple pages of image information are temporarily stored in the image memory, and this is read out the next time, and when the reading is completed, all the stored image information is erased. If, for example, there is an error in even one page of multiple pages of image information that has been stored, it is necessary to erase the entire image memory and reload all the image information into memory. There was still room for improvement in that it was difficult to make corrections.

In view of this problem, it is an object of the present invention to make it possible to easily modify a part of the image memory.

A copying device is capable of selecting and copying document images up to a second desired page from memory, or selecting any plurality of images from memory and copying any number of images in any order. Although disclosed, the invention is not limited to such devices.

When is pressed, the original is exposed by the lamp 303, and the first page is stored in area 1 (hereinafter referred to as a page or frame) of the image memory 304. Next, when the second page of the book manuscript is placed on the manuscript table and the memory switch MR is pressed again, the memory is moved and the image information of the second page is stored in the memory area 2. Thereafter, in the same manner, original images of up to 10 pages are stored in the image memory.

Lamps 303, 403 are activated by the write signal WS1 read/erase signal from controller 309. LCD 407
is a mixture of 5% cholesteric liquid crystal and nematic liquid crystal, which has an image memory property of about 2 hours. Reference numeral 508 is a power supply for storing an image in the memory 407, which generates a voltage of several volts in the form of a sine wave or square wave of approximately several kilohertz. 509 is a memory erasing power supply with a frequency of several 10 KHz to 1
Generates a sine wave or square wave voltage of about 00KHz.

508 and 509 apply voltage to the memory via electrodes 405 and 408.

510 and 511 are switches for writing and erasing, and the write signal WS1 from the control unit 309 and the erase signal ERS
Turns on. Reference numeral 433-1 is a switch for detecting the initial position of the memory 304 and stopping memory movement, and is turned on by optically detecting, for example, a mark placed in a non-image area of the memory. 433-2 is an optical switch that similarly detects the end of the memory, and detector 41 is a CCD (Charg
A solid-state self-scanning photodetector called eCoupled Device
e5canner). This is provided so that an image of a 1 bit portion (one pixel) can be detected in the X-axis direction and an image of the document can be detected in the Y-axis direction. 406 uses OPC (organic semiconductor photoconductive layer). This allows for high light transmittance.

FIG. 6 shows an example of COD. In the figure, l is CCD411
Indicates the length of the light receiving section. For example, FairChild's CCD12111A is 26 mm' and 1728
It has pits in the y direction. In other words, it has 65 bits of pixels per mm. By the way, usually 10 per mm
It can be said that if there are pixels in the pit, the resolution is sufficient for the human eye, so the image formed on the C0D 441 should be reduced to 1/6.5 of the original image on the platen 302. become. The CCD 411 has a memory 304
The width of the stored image can be imaged at the same magnification through the well-known optical element array 410.

Therefore, since the resolving power of the liquid crystal is 40 bits per mm or more, the COD can read out images without impairing the resolving power.

Since the width of the memory 304 can be made 26 mm, which is the same as l of the COD, the memory can be made very small. By the way, the image part of an A4 size (290x210) book manuscript is usually
Since it is 250 x 170, if this is reduced to 1/6.5, the width becomes approximately 26 mm, which can be stored in the above memory. Therefore, the length of the memory capable of storing 10 pages of originals is approximately 400 mm, assuming a space of 1 mm.

By the way, if the memory 304 is shaped like a disk and the memory areas 1, 2, and 3 are arranged around the disk as shown in FIG. 7, a large number of pages can be stored and a compact memory can be constructed. By the way, about 300 mm diameter disc has 20
Can memorize pages. In addition, in FIGS. 8 and 9, 434-1 on the memory plate indicates the initial position of the memory with the switch element 433-1, and 434-2 indicates the memory end with the switch element 433-1.
-2 mark for detection.

FIG. 8 is a perspective view of an example of a copying apparatus equivalent to the apparatus shown in FIG. A well-known polygon mirror can be used as the deflection mirror 416, and this can be rotated by the motor 414 to scan the photosensitive drum 400 with a reflected beam. 438 is a beam detector and the signal BD (Fig. 1)
Output. Providing the beam detector 439 at the left end of the drum reduces errors in the scan restart timing in the y direction.

In order to reduce the original image on the platen 302 to 1/6.5 and store it in the memory 304 without increasing the size of the apparatus, the optical path as shown in the figure can be used. In this case, the platen 302, While moving the memory 304 at a speed difference according to the reduction ratio, slit exposure is performed to form an image on the memory.
2 is located at a position shown in FIG. 8 so as not to interfere with memory movement.

The pulse motor 409 changes the memory area during writing and erasing, and moves the memory in the pit direction during reading.

In addition, the amount of area movement and pit movement can be determined by the number of drive pulses of the pulse motor, and forward rotation of the pulse motor causes movement to the right of the X-axis, and rotation of the pulse motor causes movement to the left.
Memory can be moved. 435 is a support member that supports the memory and allows the memory to be moved along the guide rail 436; 437 is a support member that supports the memory 435 with a pulse motor 409;
This is a boob for moving the object. It is also possible to move the memory in a pinion rack manner by providing a pinion gear on the pulse motor or a rack gear on the memory.

When using a disk memory, it is moved in parallel to the writing section and the reading section before each process starts, rotated during erasing and frame movement, and moved in parallel pits during scan writing and reading.

To explain the operation, the original on the original platen 303 is irradiated with light from the exposure light source 303, and a reflected image is formed on the memory by the lens system 503. When a reflected image is formed on the memory while the write switch 510 is on, the resistance within the photoconductive layer changes depending on the density of the original, and the voltage applied to the liquid crystal 407 changes. Therefore, the light transmittance of the liquid crystal also changes depending on the original image. That is, the document information is temporarily stored in a composite memory made up of the liquid crystal and the photoconductive layer. Erasing is performed by uniformly irradiating light from the lamp 403 onto the composite memory and pressing the switch 51.
1 and applying an AC signal from the power supply 509 to the memory.

When reading information stored in the memory, when the memory is uniformly irradiated by the light source 403, the light transmittance of the memory differs depending on the memory information, so a transmitted image of light and shade depending on the information is optically detected by the lens system 410. The image is formed on a device (CCD) 411.

The CCD 411 serially outputs a voltage according to the shade by self-scanning. The beam from laser image 415 is intensity-modulated by the voltage.

The scanning speed of C0D411 in the y direction is the polygon mirror 41
If the scanning speed is the same as the scanning speed of 416, beam modulation can be performed directly with the output of the COD, but if it is different, the output of the COD can be stored once in a buffer memory and read out in synchronization with the scanning speed of 416. The controller 309 is a system including a well-known computer as described below, and has a page memory number set, a register for counting, and a register for counting the number of books. It is shown in Table 1.

Chapter 1 Table The detailed control operation by the controller 309 will now be described.

After the power is turned on and the heater of the fixing device 426 reaches a predetermined temperature, the reading light source 403 and the switch 511 of the memory erasing power source 509 are turned on, and the pulse motor 409 is turned on to move the memory and erase the contents of the memory. Clear all (
Step 701). Note that this operation can also be performed immediately after turning on the power. When the memory has been moved from end to end and cleared, the means for clearing is turned off by the memory end detection switch 433-2 (step 702).

Note that in the determination step such as step 702, N is no,
Y indicates yes.

After the lamp 403, power supply 511, and motor 409 are turned off upon completion of memory erasure, the control circuit 413 includes a scan count register SBR, a page memory area count register MAR, and a register CMR that counts the number of books.

Display drive registers MAC and CMC are cleared (steps 701 to 704). Thereafter, the memory is returned to the memory start position and set (step 705).

That is, the pulse motor is rotated in reverse until the switch 433-1 detects the start mark. The image memory is now ready and ready for writing.

When the first page of the original is set on the original platen 401 and the memory switch MR on the panel is turned on, the exposure light source 402 flashes and forms an image of the original on the memory. When the power source 508 is activated at the same time, image information is recorded on the liquid crystal 407 (step 708).

Note that another method for storing the image in the memory is to perform slit exposure on the original while moving the document table, lamp, and optical system lens. After the memorization is completed, turn off the lamp 402 and power supply 508, and turn off the pulse motor 409.
The memory board is moved to the right by one frame, and the memory register MAC is incremented by 1. Then, it is determined whether the memory switch MR is turned on (step 706).

Thereafter, in the same manner, the required number of documents are sequentially stored in the memory. After storing a multi-page manuscript, turn on the memory end switch ME and the sequence flow will proceed to step 7.
Proceed to step 11 to allow other information to be set. here,
Set the required number of books using number key C8S and press register CM
Store in C.

(Continue to print) Next, turn on the start switch CPB (Step 7)
12) Memory reading and recording operations start.

The y-axis direction of the memory is read by the CCD 411 by self-scanning by an external clock pulse (not shown) of the CCD 411. The X-axis direction is scanned by the movement of the memory board by the pulse motor 409, and one bit is read by the CCD 411. In short, 1542 minutes of reading is CCD41
1. Further, the leading edge of each frame of the memory can be optically detected by a position detection hole (not shown) provided in the memory for accurate positioning.

When continuous recording starts, the page register SBR is first set to zero. Then, the leading end of memory area 1 is set at the memory read position (step 714).

This further includes an optical switch in the continuous part, and marks 434-
This can be done by operating the motor until 1 is detected.

At this time, the chargers 418 and 419, the lamp 420, and the developer 421 are operated to start executing a known electrophotographic process (step 715). After the surface of the photoreceptor charged by the charger 418 passes through the surface of the charger 418, the memory reading light source 403 is turned on to perform the first scan in the y-axis direction.

The pickup roller 423 is also turned on to feed one sheet of transfer paper (step 716).

The image formed on the CCD 411 is taken into the COD memory (step 717), and the COD is moved in the y direction in synchronization with the operation of the laser scanner 414 to scan in the width direction of the photoreceptor (from left to right). Scan (step 718)
.

Then, the time-series electric signals are taken in from the CCD to the amplifier 41.
The signal is input to the semiconductor laser oscillator 415 via the signal line 2, takes in the luminance of the laser, and modulates it according to the magnitude of the signal. The laser beam carrying image information is deflected in synchronization with the scanning of the CCD in the y direction, and is irradiated onto the rotating photosensitive drum surface via the F-θ lens. When the '1st scan in the y-axis direction is completed, the laser beam is incident on a fixed beam detector provided at the end of the width of the photosensitive drum surface. Upon detection of this incident light, the COD y-axis scan is stopped and switched to the next y-axis scan (
step 719). That is, when the detector performs a detection operation, the pulse motor 409 is driven by one step to advance the memory by 8 minutes in the X-axis direction (step 720). Then, the register SBR is incremented by 1, and the lamp 403 and paper feed roller 423 are turned off (step 721). Incidentally, the number of scans in the X-axis direction for one memory frame, for example, 2970 (resolution) for A4, is stored in advance in the register SBC. Therefore, the number of registers SBC is the first register SBR.
When the number matches the number of frames, scanning for one frame is completed (step 722). Since we have just incremented by 1 bit, we return to step 717, start scanning in the y-axis direction again from the initial position, and transfer the image information formed on C0D411 to CCD4.
Similarly, the second line information is recorded on the photosensitive drum in synchronization with the laser scanner 414.

This operation is repeated, and when the maximum number of scans determined by the register SBC is completed, the process proceeds to the step of reading and printing the next page.

On the other hand, the photosensitive drum 400 is AC charged by the charger 419 and simultaneously exposed to a laser beam, and its exposed surface is entirely irradiated by a lamp 420 to form a high contrast electrostatic latent image. The latent image is developed with toner in a developer 421 to form a visible image. This developed image is transferred by a charger 424 to a recording paper 422 fed by a roller 423, and the transferred material is fixed by a fixing device 426 and discharged onto a tray 427. In other words, one record of the first page of the first bird was obtained.

Next, the step motor 409 is activated to shift the memory board, move the next memory frame to the memory readout area (step 728), and increase the number of registers MAR by +1.
Step 724), set the X-axis scan count register SBR to zero (Step 725), and compare the count register MAR and memory register MAC every time reading of the l area is completed (Step 726), but they do not match. In other words, when the recording of all the memory is not completed, the next memory frame is sequentially read out (step 716), and the second page is recorded after feeding the recording paper, reading the memory, and forming a latent image in the same manner as the first page. Complete. Thereafter, the recording of one book is completed by continuing to record the number of pages stored in the display register MAC in the same manner. At this time, the tray signal T
Take out D and slide the tray as described above to make a cut in the book.

In addition, the memory movement by the pulse motor and the photosensitive drum 4
It is synchronized with the rotation of 00. In other words, the laser beam is 1
The drum and pulse motor are synchronized so that the time from the end of a line scan to the start of the next one line scan is equal to the time to move the memory one bit in the X direction.

Thereafter, the book count register CMR is incremented by 1 (step 727). Since the desired number of books is stored in the memory CMC that displays the number display CMCD, it is determined whether the number matches the counter register CMR (step 728), and if it does not match, step 713 is executed again. Step 714) of reversing the pulse motor 409 to return the image memory to its initial position; memory area 1;
The memory is read out again and recording continues. Thereafter, the recording operation is similarly performed for the required number of books set on the display CMCD, and then the operation is stopped (step 729). At this time, the image information stored in the memory is also cleared (step 701).

In this example, in the tray 308, the pages are printed in order from the bottom, starting with the initially read page and continuing to the last page, but if the reading from the memory is reversed and the last page is read and printed, the page order is reversed. I can do it.

Although an example in which an optical memory is used as the image memory has been described, it is clear that similar effects can be obtained by using a memory medium such as a semiconductor memory, a magnetic disk, or a magnetic tape.

I also explained using electrophotography as an example of a recording method.
A similar effect can be expected by using an inkjet method, contrastography method, electrostatic recording method, etc. in which an ink gun is controlled by the output of a CCD.

Further, the above control flow is executed by using a well-known computer system as the controller 309, and by its program, for example, a microcomputer system (μCOM 4 et
c) can be carried out by those skilled in the art, so the details will be omitted.

FIG. 9 shows (1) reading and printing from memory in the opposite order of storage to make a desired number of copies, (2) or (3) making a single copy or multiple copies of any memory area. ) or a control flow diagram for successively printing from an arbitrary memory area to another area and making a desired number of copies. Switch F/R for forward/reverse selection,
A panel 301 is provided with a switch IR for specifying an arbitrary memory area and a switch SPB for copying only an arbitrary area. Each copy mode is (1) forward/reverse mode,
(2) Random single mode and (3) Random sorter mode.

When the original image has been stored in the memory as described above (step 707), the numeric keypad CC8 is turned on and the area number is entered in the register IR (step 707-1). Determine whether switch IR is on (step 707-
2) When on, another register MACC is set at step 70.
Reset as shown in 7-3. That is, the number in register IR is subtracted from MAC, and it is incremented by +1. This is M
5tore to ACC. In other words, the number of remaining areas is stored. 707-4 to 707-9 will be described later. Then, it is determined whether the print button CPB is on (step 712), and then it is determined whether the F/R switch is on (step 714-1). When it is on, the pulse motor is operated to print in the reverse direction, the memory end position is set to the read position, and the reverse flag FLAGR as data indicating the reverse mode is set in another memory (714-2 ). When it is off, in order to print in the forward direction, the memory start position is set to the read position as in step 714 in FIG. 3, and FLAGR is left at 0 (step 714-3).

Register I indicating the initial address in forward mode
When it is determined that the number of 5tore L/R is 1, the process proceeds to step 715 as shown in FIG. 3 (step 714
-4), start printing from the beginning (715~
721). Steps 722-1 and 722-2 will be described later.

In the reverse mode, reading and printing starts from the last memory page. When one page has been read, it is determined whether the mode is forward or reverse (step 723-1).

In the reverse mode, that is, when FLAGR is 1, the memory is moved two frames to the left by the pulse motor, and in the forward mode, that is, when FLAGR is reset, the memory is moved one frame to the right (step 723-2). .3)
. Note that steps 714-8 to 714-10 will be described later. Since ER=MAC now, the program is passed in this example.

Also, if the reverse mode and the number of books stored in the register are multiple,
When the copying of the first page of the memory is completed, the process returns to step b (step 713) via 728-1.

Then start copying from the last page again. In this manner, reading and copying one book in the reverse direction is executed, and the process is repeated as shown in FIG. 5 to complete the copying of the desired book set using the ten keys. Note that it is not possible to change the number of books or the next desired number of pages by directly operating the numeric keypad during copying. Further, in step B, it is also possible to determine whether an input to cancel book copying is made and to wait in step 711 so that a change can be made.

If a forward mode copy is to be made from the second page of the money policy, 2 is set in the initial register IR in advance (step 707-1).
). Then, the number of 5tore of page register MAC is (-
1) Do (step 707-3). Let this be MACC. Then, in step 714-1.3, the memory is set to the memory start position (left end) and FLAGR is reset. Then, in step 714, it is determined that IR is not 1, and the memory is moved one frame to the right (step 71
4-6), -1 from register IR (step 714)
-7). Then, IR becomes 1, so step 71
Proceed to step 5 and start successive printing from the second page according to the above-described procedure. Since MACC has been incremented by -1, the process returns to step b again on the last page. Similarly, when copying from the third page, printing is started after skipping the memory by two frames, and similarly returns to step b at the last page.

In the case of the reverse mode, successive printing starts from the last page by executing steps 714-2 and 715. Register MA
Since the number C has been corrected according to the number in the register IH, it is determined YES in step 726 when the second page is reached, the book counter is incremented by 1, and the process returns to step b.

In this way, in the forward direction, copies are made from the second page to the last page, and in the reverse direction, the second page from the end is automatically copied. In other words, any desired page can be copied.

After copying the desired volume or when the number of volumes is 1, turn on the process means (step 729) and registers CMR, IR.
, MAR, MACC are cleared (step 730).

Furthermore, as will be described later, copying in the reverse mode can be performed using the ERS key based on the number of stored pages. Note that step 714-
After executing 4,714-8, register IR.

The initial number (by key C8S) is set in ER. In addition, the coma raft in FIGS. 2 and 8 is a control unit 309.
This can be executed by counting the power pulses of the pulse motor to a predetermined value and turning off the motor. 297 to move one frame
This is possible with a count of 0+2. This can be done by storing the number of pulses in ROM or RAM in advance and outputting that number of pulses from the controller 309 to the motor, or by detecting the drive pulse and using a computer to output that number of detected pulses. It is also possible to count and turn off the motor. This can be applied to the movement of one bit in the memory, and can also be applied to the image memory position set by storing a predetermined number of pulses therefor in the ROM or RAM.

Next, print reproduction (random mode, random sorter mode) of an arbitrary page in the memory will be explained.

SPB in FIG. 4 is a key for making a desired number of copies of only a desired page, and ER3 is a key for copying a page set by the IRS key at the true speed set by this key. When the single key SPB is turned on and then the numeric keypad C5S is turned on, the original images of only the pages previously set using the IRS key and the numeric keypad C8S are read out from the memory and printed by the number of numeric keys turned on later.

That is, as mentioned above, first, by using the key IR8, the register M
The number in register IR is subtracted from the number in AC and stored in another register MACC. MACC is used for book printing (707-3).

Incidentally, when the numeric keypad C8S is turned on again next time, the number is stored in the register ER. Register ER indicates an arbitrary ending page in the case of instantaneous continuous copying.

However, when the single page key SPB is turned on after the key IR5 is turned on or after the key 707-4 is turned on, the flag S is set.
Set the number of copies using the numeric keypad and press the copy key CPB.
(707-5 to 707-7).

Then, jump to routine ① and set the initial memory location and memory read area as described above (71
4-4 to 714-7). After setting the position, the flag S after printing of one frame for printing out the page is determined according to the above-described procedure (step 722-2).

If you are copying a single page multi of the current type, proceed to step 727 without executing steps 723 to 726,
Increment register CMR. Thereafter, registers CMC and CMR are compared (step 728-1).

If the CMR does not match the CMC, the flag S is checked again and the process returns to the routine ◎, where the same page is again read from the beginning and printed. When CMR and CMC match, the operation of the process syns is stopped and the routine returns to routine (3), where it waits. If you perform the same key procedure again, you can make a similar copy without canceling the memory image. That is, by sequentially turning on the numeric keypad CSS, IRS key, and copy key CPB, another desired page can be copied. Also, by sequentially turning on the numeric keypad, IRS key, numeric keypad, and copy key, you can make multiple copies of different pages.

Further, the ERS key shown in FIG. 4 is used to execute copying between desired pages in the image memory for a desired volume by aligning the pages. If you turn on the numeric keypad CSS and initial page key IR3 in sequence, then turn on the numeric keypad CSS and end page key ER3 in sequence, and then turn on the numeric keypad and copy key CPB in sequence, the number on the first numeric keypad will change from the number on the second numeric keypad. You can repeat the copy between the numbers as many times as the number on the third numeric keypad. Forward/reverse key F/
If R is turned on immediately after the copy key is turned on, even in the above-mentioned reverse mode of copying, the desired number of copies between pages can be made in the order of the pages.

In other words, after turning on the RS key and the numeric keypad in sequence, turning on the ERS key changes the register MACC to step key 7.
Corrected by the number stored in the register ER as shown in 07-9,
Restore the numerical value. Start copying the number of copies using the next numeric keypad CSS and copy key CPB. In other words, if the memory storage page is 10 pages and the copy range is 2 to 9 pages,
The number of registers MACC is eight.

When the switch FR is turned in the forward direction after the copy key is turned on, the register IR is set to 1 by executing steps 714-3 to 714-7.
The memory page is shifted to the right page (memory is moved to the left) until . Copying is then automatically started from that page as described above. Steps 715 to 726 are executed, and when the copying of the 9th page (copying 8 pages) is completed, the count number in the register MAR matches MACC, so the register CMR is incremented (step 727). Copying for 8 pages is continued in sequence, and when copying for one book is completed, copying for two plates is started again from routine b. When the desired number of books set in the register CMC has been copied, the process advances to routine d and waits.

After turning on the copy key, when reverse copying is set using the switch FR, the reading position is first set to the last page of the memory in which the image is stored as described above (step 714-
2). If the number of atore in the register ER is different from the last page, shift the memory to the left page (move the memory to the right) until the register ER becomes equal to the memory register MAC, and initialize the memory to the desired last page (714).
-8 to 714-10).

Then, as mentioned above, register MAC is written in the reverse direction from the last page.
The pages determined by C are sequentially copied.

After copying the desired number of copies in the same way as above, routine d
The process proceeds to step 730, clears each register (step 730), and waits.

As described above (single copying or multiple copying of only the desired page is possible, it is also possible to copy sequentially from the first desired page to the second desired page, and it is possible to copy the required number of books between desired pages repeatedly) , and automatic accounting is also possible.Also, there is no need to add a sorter device to distribute copy paper.
Copying a large number of copies in page order becomes easy.

In addition, to cancel the image in the memory, step 7 is performed by turning off the switch SW that turns on the power to the device.
This can be achieved by executing 01. Of course, it is also possible to provide an image clearing key and perform the input determination in routine 730 before proceeding to step 701.

FIG. 12 is a control flowchart that makes it possible to partially clear and partially change the image memory. By inserting this between step 730 and step 701-1 in FIG. 11, this control can be achieved. step 800
determines whether the erase switch 403 is on. switch 40
3 is provided on the panel 301 (FIG. 4). If a new copying operation is to be performed without turning on the standby switch 403 after copying is completed, control moves to step 707-1 described above. When the switch 403 is turned on, the number of the next turned on numeric keypad C8S is erased as page data in the register IC.
5tore is performed on R (step 801). Then, drive the motor to move the memory to that page (80
2). Then, the erase power supply 511 is turned on and off to clear the image of that page (803). After that, initialize the memory as in step 705 (804)
. Thereafter, a document image storage process similar to steps 706-709 can be performed to store a new image in memory on the cleared page. Thereafter, it waits to receive a read and print command.

In addition, as shown in FIGS. 9 and 12, if an address map of a large number of document images stored in the memory is created, only the desired document image can be searched for and printed out using only a key, making document management easier.

FIG. 13 shows a method for copying a desired first page of the memory and then copying another second page, and a method for sorting a desired number of the two types of pages and printing them out. (Random Jump Mode) This control can be achieved by replacing steps 715 and following in FIG. 11 with this.

2nd page as 1st page, 9 as 2nd page
Suppose that you make two copies of the page number in normal mode. As described above, after copying the second page, the forward/reverse flag FLAG is set.
It is determined whether R is 1 (step 723-1), and when the mode is forward mode, it is further determined whether the jump mode is set (step 901). This is because the microcomputer determines the state of switch JP, which selects jump or normal as shown in FIG. When it is normal, copying is executed according to the procedure shown in FIG. memory when jumping,
Shift to the page location set in register ER. That is, the frame count is -2 of the number stored in register MACC, (
MACC-1) space count is performed and the motor is driven. This address control can also be performed by counting the motor drive pulses corresponding to the frames and spaces as described above. When the second page is set, the reading print step 71 in FIG.
Execute the same operation as steps 5 to 722 (step 902) L/
Then, the second page (9th page) is copied and ejected onto the first copy. Then, the book number counter register CMR is incremented (step 727).

Then, the process returns to step 713 and the forward/reverse switch F/
The state of R is determined, and when the mode is in the forward mode, copies of the second and ninth pages are repeated and ejected as described above. As a result, the counter register CMR matches the number (2) stored in the register CMC (728-1), so the process waits in standby mode.

When copying 2 copies of the 9th page and the 2nd page in the reverse mode, in step 904 after copying the 9th page, the memory is moved by the number of frames and spaces stored in the register MACC, and the 2 copies are copied.
Set memory address to page.

Then, as described above (reading and printing in step 902 is executed), copy sheets are stacked on the output tray 308 in page order 9-2-9-2 from the bottom.

Similarly, copy programs and copy order programs for the first to third pages are also possible.

It is also possible to scan and store one image in the entire area without providing space in the memory 304, and to print out a plurality of partial copies from the memory 304 using the procedures shown in FIGS. 11 and 15.

Furthermore, if the forward/reverse switch F/R is switched during copying, the mode will be automatically switched even when copying one book is finished. Also, the computer flowcharts 3, 9, 12,
As is clear from FIG. 13, pre-start by key CPH is inhibited to prevent this operation while writing a document to the memory and clearing the memory image. Also, during printing operation, the switch ICL and 40 are used to clear the memory.
Even if 3 is turned on, it is locked so that the clear operation does not occur. It can be cleared for the first time in standby. Similarly, the operation of storing an image in the memory 304 using the memory key MH is also prohibited during the print operation. In this way, it is possible to prevent erroneous copying caused by erroneously turning on the key during a memory storing operation or clearing, and it is also possible to prevent memory images from being swapped due to erroneously turning on a key during a printing operation, thereby preventing erroneous copying.

In addition, in this embodiment, a number that cannot be erased is stored in advance in the corner of multiple pages of the image memory sequentially from the left page, and when the number is read out along with the image and printed, the page is automatically written at the lower right corner on the copy paper of the reproduced image. can. Also, considering the case of copying from the middle of the memory by turning on the IR8 and ERS keys,
A lamp is installed on the lens or near the COD to illuminate the upper right corner of the bar lens (Selfoc lens) 41O corresponding to the page number. In the case of copying from the middle or in the case of single page copying, turn off the lamp. By closing it, you can prevent the page numbers from being played.

FIG. 10 is an example of a circuit diagram when a microcomputer TMS9900 (Texas Instruments Inc.) system is used as the controller 309 in FIG.
3, 510, 511 etc are the output loads as in Figure 2, 402D and 403D are well-known driver circuits for lighting the lamp, and 510D and 511D are relays for turning on the switch. Each load is connected to the output port of the CPU via a driver. A motor on/off signal line and a forward/reverse rotation line are inputted to the pulse 409 from the CPU.

FIG. 11 is a flowchart showing an example of a program when performing the control shown in FIG. 2 using 7MS9900, and is shown in machine word mode. A microcomputer system generally has a memory R9M for storing programs in machine words, and a memory RAM for loading and unloading data when executing this program. Register MAR, MAC
etc. use this RAM. Command words such as LOCR in the figure are in accordance with the 7MS9900 product manual.

BL and BLWP are programs that jump to subroutines, such as steps 717 and 718.
The operation of reading memory contents into D and the operation of outputting them are executed in a subroutine. The contents of these subroutines can be easily created by a company in the art. An actual program example is shown in Table 2 as an instruction list. Programming can be done in this way.
Address from 00H (hexadecimal), output port address Table 2 Power on ↓ AOOI Ll 1. ＞0OOALLl
12. >0100 LDCR1,15 ↓ BLWP■PMXI 701 ↓ LI 12 >0200 Similarly, the control flow shown in FIG. 9 can be converted into program code.

In this way, in this embodiment, multiple pages of a manuscript are stored in the image memory once, and then converted into electrical and optical signals to record one book, and then repeated to make several copies. Therefore, it is only necessary to store the required original in the image memory in advance. Therefore, by simply memorizing the information in advance, it is possible to produce multiple copies of the same pages completely automatically, thereby saving the operator's labor. Furthermore, a sorter for aligning pages is no longer necessary, and the entire machine can be made smaller. Further, it is possible to automatically copy a plurality of manuscripts and articles of any shape at high speed.

Furthermore, if an optical memory such as a liquid crystal is used as the memory, intermediate tones of shading can be easily memorized and the original image can be faithfully reproduced many times. Moreover, it can be done economically at extremely low cost.

Furthermore, when recording with an electrophotographic copying machine, it is necessary to hold the copy until the fixing device, etc. rises to a predetermined temperature after the copying machine is powered on, but the original information can be stored in memory during this time, reducing the required copying time. I can do it.
