Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic document FI embedding method and apparatus in an electronic copying machine or the like. In particular, it relates to a copying machine having an electronic sorter function. In recent years, as PPC copiers have become smaller, faster, and more multi-functional, they are not only capable of producing identical copies from a single sheet of original, but also have automatic document feed (hereinafter referred to as ADF) and automatic page alignment (hereinafter referred to as sorter). Automatic document processing devices having an automatic bookbinding function, such as , etc., are becoming widespread.

Conventionally, most electronic copying machines 8 have an ADF mechanism separately attached as shown in FIG. 1.2.

Briefly explaining FIG. 1, the lowermost document is fed from a tray 2 in which sheet documents 1 are stocked to a roller 3 through a feed belt 4 to a document table 5. As shown in FIG. After the original i-height is fixedly set on the document table, the optical system is moved back and forth to perform a copying operation using the well-known electronic copying machine process of exposing the document to slit light. After copying the original, the feed belt 4 reverses and the claw 6 returns the original to the completion tray 7.

Thereafter, the same operation is repeated to create a printed matter with all the pages of the automatic book. However, each time a second copy is to be made, the original from tray 7 must be returned to tray 2 by hand, which makes handling of the original a sloppy process and prevents the user from leaving the copying machine.

In addition, in the apparatus shown in FIG. 2, the lowermost document is sent from the tray 8 to the first feed roller 10 by rollers 9, and then the document is sent onto the document table by rollers 11 and 12, and fixedly set. Ru. The original is exposed and a copy operation is performed. After copying is completed, the rollers 12 operate to eject the original from the original platen, and the rollers 13 set the original on the tray 8 again. A similar operation is repeated to create a printed matter with all the pages of a plurality of books.

However, when a large number of books are to be bound, the number of times the originals are set on the original table and ejected from the original table increases, and there is a risk of damaging the valuable originals.

Also, the originals may be fed in duplicate, which may result in a book with missing pages.

Another method is to copy the required number of copies from one manuscript, use a sorter to classify the copies by the required number of copies, and repeat the process by exchanging the manuscript one after another. This method eliminates the need to set the original on the document table many times, and there is little risk of damaging the original. However, if a large number of copies are to be made, the sorter must be large-scale, and therefore the mechanical space for temporary storage becomes large. , Moreover, the classification function becomes complicated.

However, in terms of operability, the former automatic document feeding method is limited to sheet documents and cannot be used with book documents. On the other hand, in the latter sorter method, the operator must be constantly turning the pages of the book manuscript until the binding is completed, which is extremely time consuming.

Therefore, even if a combination of an automatic document feeding system and a single sorter system is used, there is no system that satisfies the requirements of not damaging the original, allowing both sheet and book originals to be used, and requiring less operator time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a copying method and apparatus having a simple automatic document processing apparatus that eliminates these drawbacks.

The present invention provides a copying method and apparatus that can automatically obtain copies of a plurality of books with the same pages by simply turning the eight pages of a book manuscript in different ways. The present invention provides a copying method and apparatus that can automatically obtain copies of a plurality of books with the same pages without attaching a sorter. The first object of the present invention is to provide a copying method and apparatus that can automatically produce copies of a plurality of books with the same pages even when a desired number of copies have been commanded and both the original and the operator leave the copying machine. SUMMARY OF THE INVENTION The present invention provides a copy control method and apparatus for automatically copying the pages of a plurality of volumes by storing one set of eight pages of a manuscript in a memory and repeatedly outputting the stored information.

In the figure, 301 is an operation panel for entering commands such as starting copying and displaying the number of copies, etc., 302 is a document table for placing originals and objects to be copied, and 303 is for exposing the originals to light. The light source, 304, is a liquid crystal.

Electrochromy, or PLZT (lead Pb.

A compound of lanthanum La, silicon Zr, and titanium Ti was published in the magazine "Television Vol29.No.

In the above block diagram, for example, when copying 5 copies of pages 1 to 10 of a book manuscript and arranging them in page order, the first page of the book manuscript is placed on the manuscript table 302, and the operation panel 302 is
1 (details are shown in Figure 6)
When R 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 as images.

Then, using the number set key C3S on the panel 301, the required number of books is stored in another memory (register). Thereafter, by turning on the start switch CPB, reading out the image signal from the image memory area 1 is started, the read optical signal is converted into an electric signal, and the time-series electric signal is converted into a laser beam signal by the converter 306.

The laser light is intensity-modulated. The photoreceptor of the electronic copying machine is exposed to the modulated beam to form an electrostatic (replacement image), and then the latent image is developed.This causes the recording of the first page.After the recording of the first page is completed, Read image memory area 2, record the second page in the same way, and then record page 1 in the same manner.
Finish recording up to page 0 (1 book). When the number of copies is finished, if more copies are desired, the image memory is returned to its original position and memory areas 1, 2 are sequentially read out, and pages 1 to 10 are copied in the same manner as for the first item.

When printing of one book is completed, a means for sliding the tray 308, such as a forward/reverse motor, is activated to move the tray 308 in response to a tray command TD from the control unit 309. For example, a tray as shown in FIG. 7-1 is used. Cam plate 30

The liquid crystal 407 is a mixture of 5% cholesteric liquid crystal and nematic liquid crystal, and has an image memory property of about 2 hours. 5
08 is a power supply for storing an image in this memory 407, and generates a voltage of several square waves or sine waves of about several KHz.

509 is a power supply for memory erasing, several tens of KHz to 100 KH.
Generates a sine wave or square wave voltage of about 2 degrees. 508,
509 applies voltage to the memory via electrodes 405 and 408. 510 and 511 are switches for writing and erasing, which are turned on by a write signal WS and an erase signal ERS from the control unit 309. 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 attached to a non-image area of the memory. 433-2 is an optical switch that similarly detects the end of the memory, and detector 411 is a CCD (Cha
solid state self-scanning photodetector (solid 5tate coupled device)
1ine 5canner). This is provided so as to be able to detect an image corresponding to one bit (one pixel) in the X-axis direction and the entire document in the X-axis direction. 406o uses PC (organic semiconductor photoconductive layer), which can increase light transmittance.

FIG. 8 shows an example of a CCD. 2 in the diagram is C0D411
Indicates the length of the light receiving section. For example, made by FairChild (
7) CCD121 is 26mm and 1728
bits in the y direction. In other words, it has 65 bits of pixels per mm. By the way, usually 10 per mm
Since it can be said that a pixel of one bit has sufficient resolution for the human eye, the image formed on the CCD 411 can be reduced to 176.5 times the original image on the platen 302. 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, the resolution of the liquid crystal is m
Since there are more than 40 bits per m, the CCD can read out images without losing resolution. Since the width of the memory 304 can be made 26 mm, which is the same as that of CCD 1, the memory can be made very small. Incidentally, the image portion of an A-size (290 x 21'O) book document is normally 250 x 170, so if this is reduced to 1/6.5, the width becomes approximately 26 mm, which can be stored in the 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. 9, a large number of pages can be stored and a compact memory can be constructed. By the way, 20 pages can be stored on a disk with a diameter of approximately 300 mm.

In Fig. 8.9, 434-1 on the memory plate sets the initial position of the memory using the switch element 433-1.
34-2 is a mark for detecting the memory end at 433-2.

FIG. 10 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 which outputs a signal BI) (FIG. 3). If the beam detector 439 is installed at the left end of the drum, y
The error in the direction scan restart timing is reduced. 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, an image is formed on the memory by slit exposure while moving the platen 302 and the memory 304 at a speed difference depending on the reduction ratio. The read lamp 403 and the detection switches 433-1 and 433-2 are located at the positions 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 bits in the X direction during reading.

Further, the amount of area movement and the amount of bit movement can be determined by the number of drive pulses of the pulse motor, and the memory can be moved to the right of the X-axis by forward rotation of the pulse motor, and to the left by reverse rotation of the pulse motor. 435 is a support member for supporting the memory and allowing the memory to move eight times along the guide rail 436; 437 is a pulley for moving the support member 435 by the pulse motor 409; 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. If a disk memory is used, it is erased by having the writing section and reading section perform 8 parallel operations before starting each process.

When moving a frame, rotate it and scan and write.

When reading, it is used in parallel bits.

Let me explain how it works. 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 can be performed by uniformly irradiating the composite memory with light from the lamp 403, turning on the switch 511, and applying an alternating current signal from the power source 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.

Is CCD 411 due to its self-scanning? IA? Serially outputs voltage according to A. The beam from laser image 415 is modulated by the voltage.

The scanning speed of the CCD 411 in the y direction is the same as that of the polygon mirror 41.
If it is the same as the scanning speed of 416, beam modulation can be performed directly with the output of the CCD, but if it is different, the output of @cc[) 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.

The detailed control operation by the controller 309 will be explained with reference to the sequence control flowchart shown in Table 1 and FIG. 4. After the power is turned on and the heater of the fixing device 426 reaches a predetermined temperature, the reading light source 403 is turned on by the switch 51 of the memory erasing power source 509.
1 and the pulse motor 409 to move the memory and clear all the contents of the memory (step 701). Note that this operation can also be performed immediately after turning on the power. When the memory is cleared eight times from end to end, the means for clearing is turned off by the memory end detection switch 433-2 (step 207). Note that in the determination steps such as step 702, N indicates no and Y indicates yes.

After the lamp 403.2 source 511 and motor 409 are turned off upon completion of memory erasure, the scan counting register SBR, page memory area counting register MAR, register CMR for counting the number of books, and display drive register MAC, CMC in the control circuit 413 (Step 701)
~704). Thereafter, the memory is returned to the memory start position and set (step 705). In other words, switch 43
3-1 rotates the pulse motor in reverse until the start mark is detected. The image memory is now ready and ready for writing.

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

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. Lamp 402 after memorization. The power supply 508 is turned off, the pulse motor 409 moves the memory board 8 times to the right by one frame, and the memory register MAC is set to +1. Then, it is determined whether the memory switch MR is turned on (step 706). Thereafter, in the same manner, the required number of originals are sequentially stored in the memory. 8
After storing the original page, press the memory end switch M.
Turning on E causes the sequence flow to proceed to step 711, allowing other information to be set. Here, the required number of books is set using the number key C3S and stored in the register CMC.

(M sale/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, reading for one line is performed by the CCD 411. 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 reading and recording starts, the page register SBR is first set to zero. Then, the leading end of the memory area 1 is set at the memory reading position (step 714). This can be done by further providing an optical switch in the reading section and operating the motor until the mark 434-1 is detected. At this time, the charger 418
419, the lamp 420 and the developing device 421 are operated to start executing a known electrophotographic process (step 715).
. -! The surface of the photoconductor charged with the charger 418 is charged with the charger 4
After passing through the surface No. 18, the memory read 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 CCD memory (step 717), and the CCD 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 at 7 blocks 41.
2, the semiconductor laser oscillator 415 is manually operated and the brightness of the laser is modulated according to the magnitude of the captured 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 first scan in the X-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 y-axis scan of the CCD 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 one step to advance the memory by one bit in the X-axis direction (step 720). Then, add 1 to the register SBR and turn off the lamp 403 and paper feed roller 423 (
step 721). By the way, the number of scans in the X-axis direction for one frame of memory is stored in the register SBC in advance, for example, 2 in the case of A4.
970 (resolution) is stored. Therefore, when the number of registers SBC matches the number of previous registers SBR, 1
This means that scanning for frames has been completed (step 722).
. Since only one bit has advanced, the process returns to step 717, starts scanning in the X-axis direction again from the initial position, and moves the CCD 41
The image information formed on line 1 is taken into the CCD 411, and information on the second line is similarly 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 charged with AC% by the charger 419.
It is exposed to a laser beam at the same time as the T-electrode, and the entire exposed surface is 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.
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 book has been obtained.

Next, the step motor 409 is operated to shift the memory board and move the next memory frame to the memory display area (step 723), and the number of registers M A R is increased by +1 (step 724), in the aforementioned X-axis direction. Setting the scan count register SBR to zero (step 725);
Then, each time reading of one area is completed, the count register MAR is
and storage register MAC (step 726);
If they do not match, that is, if recording of the entire memory is not completed, sequentially escape the next memory frame (step 716).
, the recording of the second page is completed by feeding the recording paper, reading the memory, and forming a latent image in the same manner as for the first page. 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 TD is output and the tray is slid as described above to create a cut in the book.

In addition, the memory paste by the pulse motor and the photosensitive drum 40
It is synchronized with the rotation of 0. In other words, the drum and pulse motor are synchronized so that the time from when the laser beam scans one line to when it starts scanning the next line is equal to the time it takes to read one bit B 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 or not (step 728). If the number matches, the process returns to step 71.
3, and the pulse motor 409 is reversed to return the image memory to the initial position. Step 714) Memory reading from memory area 1 is performed again and recording continues.

Thereafter, in the same manner, the recording operation is stopped for the required number of books set on the display CMCD.

(Step 729), and the image information stored in the memory at this time is also cleared (Step 701). In this example, in tray 30B, from the bottom to the initial read page 1
Although the pages are printed starting from page 1 to the last page, the order of the pages can be reversed by reversing the reading from the memory and reading and printing from the last page.

Although an example in which an optical memory is used as the image memory has been described, a semiconductor memory or a stone disk may also be used.

It is clear that similar effects can be obtained using memory media such as 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.

The above control flow can be executed by a person skilled in the art using a well-known computer system as the controller 309 and its program, for example, a microcomputer system (μC0M4 etc.), so the details will be omitted.

FIG. 11 is a control flow diagram for making a desired number of copies of memory read prints in the opposite order of storage, or reading and printing sequentially from an arbitrary memory area and making a desired number of copies. A switch F/R for forward/reverse selection and a switch IR for specifying an arbitrary memory area are provided on the panel 301.

When the original image is stored in the memory as described above (step 707), the numeric keypad CC3 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
), the register MAC is reset as in step 707-3. Then, it is determined whether the print button CPB is on (step 712), and it is determined whether the F/R switch is on (step 714-1). When it is on, the pulse motor is operated to set the memory end position to the read position and set the reverse flag in another memory. When it is off, the memory start position is set to the read position as shown in step 714 in FIG. (Step 7
14-3). When the number of registers IR is 1, the process advances to step 715 as shown in FIG. 5 (step 714-4), and reading and printing are started from the beginning. When one page has been read, it is determined whether the page is forward or reverse in step 722-1 (step 72
3-1). Reverse sharpening, move the memory 2 frames to the left by the pulse motor, and when positive, move the memory 1 frame to the right NS
L"J (step 723-2.3), and successive copying of one book in the reverse direction is executed as shown in FIG. 5, and this is repeated to complete the copying of the desired type set using the ten keys.

If we now copy from page 2, the initial register IR
is set to 2 in advance (step 707-1). Then, the number of page register MAC is decreased by 1 (step 707
-3). If it is determined in step 714-1 that IR is not 1, it is determined whether the IR is forward or reverse (step 714-5).
). If positive, move the memory one frame to the right (step 7
14-6) The register IR is decremented by 1 (step 714-6), and since IR becomes 1, the process advances to step 715 and starts reading and printing from the second page. In the opposite case, the IR is set to 1 without moving the memory 8. Therefore, reading and printing starts from the last page. Since the number of registers MAC is corrected according to the number of registers IR, when the direction is forward, the copy is made from the second item to the last page, and when the direction is the reverse direction, the second page from the end is self-copied. In other words, any desired page can be copied.

What is called frame shift in Figure 4.10 is the movement of the length memory including the space between frames.
This can be executed by having the control unit 309 count the power pulses of the pulse motor to a predetermined value and turn off the motor. It is possible to move one frame with a count of 2970+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 309.6), or by detecting the drive pulse and using a computer to output that number of detection pulses. , it is also possible to count. This means that 1 bit B of memory
This can also be applied to image memory position sets by storing a predetermined number of pulses in the ROM and RAM.

Next, print reproduction of an arbitrary page in the memory will be explained.

SPB in Figure 6 is a key for copying only the desired page and the desired number of copies. After turning on SPB, turn on the numeric keypad CSS,
Original images of only the pages set using the IRS key and numeric keypad CSS are read out from the memory and printed by the number of numeric keys turned on later.

That is, by using the key IR5, the amount related to the number of IRs is subtracted from the number of registers MAC and stored in another register MACC. M
ACC is used for book printing (707-3). Next, turn on the numeric keypad again and store the number in register ER. Register ER indicates an arbitrary end page of sequential copying.

However, when the single page key SPB is turned on next time, the flag S is set and the number of the end page register ER is set in the register CMC (707-5 to 707-7). Then, the routine jumps to routine ■, and the initial memory location and memory read area are set as described above (714-
4).

When the page is printed out as described above, the flag S is determined (step 722-2), and since it is a single page copy, the process proceeds to step 727, counts the number of copies in the register CMR, and compares it with CMC after setting ( Step 728-1). If CMR does not match CMC, return to routine ■ via determination of flag S,
Control is performed to read and print the same page again from the beginning. When CMR and CMC match, the process returns to routine (2) via flag S determination and waits. If you perform the same key procedure again, you can make a similar copy without canceling the memory image.

The ERS key in Fig. 6 is used to copy between desired pages in the image memory for the desired volume by aligning the pages, and turns on the numeric keypad and initial page key IR3 in sequence, then turns on the numeric keypad and end page key ER3 in sequence. Turn on, then numeric keypad, copy key CPS
By turning on sequentially, copies between the number of ten keys in FIG. 1 and the number of ten keys in FIG. 2 can be repeated as many times as the number of ten keys in FIG. 3.

That is, after turning on the IRS key and the numeric keypad in sequence, when the ERS key is turned on, the register MACC is calculated and stored again according to the number in the register ER as in step 707-9, and the process waits for the next numeric keypad and copy key to start copying the number of copies. do. In other words, the memory storage page is 10 pages, and the copy range is 2~
If there are 9 pages, the number of registers MACC is 8.

When the switch FR is turned in the forward direction after the copy key is turned on, the memory is shifted to the right page (the memory is moved to the left) until the register IR becomes 1. After that, as mentioned above, copying starts automatically from the initial page, continues to copy 8 pages in succession, and when one book is finished, starts copying 2 times from routine ■ again.
When the desired number of books has been copied, the process goes to routine d and waits.

When the switch FR is turned in the reverse direction after the copy key is turned on, the frame is shifted to the left page of the memory (the memory is moved to the right) until the register ER becomes equal to the memory register MAC, and the memory is set to the desired end page. Thereafter, as described above, copies of pages determined by the register MACC are sequentially executed in the reverse direction from the last page. When the desired number of copies has been copied in the same manner as above, the program proceeds to routine d, clears each register, and waits.

As described above, it is possible to make multiple copies of only the desired pages, and it is also possible to automatically reconcile the required number of books by sequentially copying from desired page to page. There is no need to attach a sorter device for this purpose, making it easy to make multiple large R copies.

To cancel the image in the memory, turn off the switch SW that supplies power to the device, and turn off the switch 7.
This can be achieved by executing 01.

Of course, it is also possible to provide a key for clearing the image, perform the manual determination in routine d, and proceed to step 701.

In addition, in this example, if a number that cannot be erased is stored in advance in the corner of page 8 of the image memory sequentially from the left page, and the number is read out along with the image and printed, the page can be automatically placed at the bottom right corner on the copy paper of the reproduced image. .゛Also, considering the case where the copy is made from the middle of the memory by turning on the IR3 or ERS key, a lamp is provided on the lens or near the CCD to illuminate the upper right corner of the bar lens (Selfoc) 410 corresponding to the number of copies. In case of copy from , in case of single page copy,
By closing the lamp, the page numbers can be prevented from being reproduced.

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 created by those skilled in the art without any additional problems. An actual program example is shown in Table 2 as an instruction list. You can program it like this. In addition, set the manual port address to the address from 0200H (hexadecimal), and set the output port address to 01.
The address starts from 00H.

The control flow shown in Figure 1 can be modified into program code.

In this way, the present invention stores multiple pages of a manuscript once in an image memory, then converts it into electrical and optical signals to record one book, and then repeats this process to make several copies. Therefore, all you have to do is store the required document 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 page alignment is no longer necessary, and the entire machine can be made smaller. Further, regardless of the shape of originals or articles, a plurality of documents can be copied at high speed. Furthermore, if an optical memory such as a liquid crystal is used as the memory, the intermediate tone of the dark flame 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 wait until the fixing device, etc. reaches a predetermined temperature after the copying machine is turned on, but the original information can be stored in memory during this time, reducing the required copying time. I can do it.
