In the same manner, the original images of up to 10 pages are stored as images. Then, use the number set key CSS on panel 301 to set the required number of books in another memory (register).

After that, 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 brightness modulated. A photoreceptor of an electronic copying machine is exposed to the modulated beam to form an electrostatic latent image, and then the latent image is developed. As a result, the first page is recorded.

Solid state line scanner called CCD (Charge Coupled Device)
It is. This is provided so that an image corresponding to one bit (one pixel) in the x-axis direction and the width of the document in the y-axis direction can be detected. 4060 uses PC (organic semiconductor photoconductive layer), which can increase light transmittance. Figure 8 shows an example of a CCD. l in the figure is CCD
411 shows the length of the light receiving section. For example FairChild
The CCD 121 made by the company has l of 26 mm and 1728 bits in the y direction. In other words, it has 65 bits of pixels per mm. By the way, usually per mm
Since a 10-bit pixel has sufficient resolution for the human eye, the image formed on the CCD 41.1 is 1/1 of the original image on the platen 302.
It will be fine if it is reduced to 6.5. CCD4
11, the width of the image stored in the memory 304 can be imaged at the same magnification via a well-known optical element array 410. Therefore, since the resolving power of the liquid crystal is 40 bits per mm or more, the CCD can read out images without losing its resolving power. Since the width of the memory 304 can be made 26 mm, which is the same as l of the CCD, the memory can be made very small. By the way, the image area of an A size (290 x 210) book manuscript is usually 250 x 170, so this should be reduced to 1/
When reduced to 6.5, the width becomes approximately 26mm, which can be stored in the memory above. Therefore, the length of a memory capable of storing 10 pages of original documents 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, about 300mm
20 pages can be stored in the φ disk. In FIGS. 8 and 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
outputs a signal BD (Fig. 3) with a beam detector.
When a beam detector 439 is installed at the left end of the drum,
The error in the scan restart timing in the y direction is reduced.
The original image on the platen 302 can be reduced to 1/6.5 without increasing the size of the device, and the memory 60 can be

03. 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. The amount of area movement and 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. can. 435
437 is a support member for supporting the memory and making it movable 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 and a rack gear on the memory. When a disk memory is used, it is moved in parallel to the writing section and the reading section before each process starts, rotated during erasure and frame movement, and parallel bit moved during scan writing and reading. Let me explain how it works. The original on the original platen 303 is irradiated with light from the exposure light source 303, and the lens system 50
3, a reflected image is formed on the memory. 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 original information is temporarily stored in a composite memory made up of liquid crystal and 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 AC signal from the power supply 509 to the memory. When reading information stored in memory, light source 4
When the memory is uniformly irradiated with 03, since the light transmittance of the memory differs depending on the memory information, a transmitted image with a density depending on the information is formed on the photodetector (CCD) 411 by the lens system 410. The CCD 411 serially outputs voltages corresponding to gradations by self-scanning. The beam from laser image 415 is intensity-modulated by the voltage. If the scanning speed of the CCD 411 in the y direction is the same as the scanning speed of the polygon mirror 416, beam modulation can be performed directly with the output of the CCD, but if the scanning speed of the CCD 411 is different from that of the polygon mirror 416, the output of the CCD can be stored in a buffer memory and then read out in synchronization with the scanning speed of the polygon mirror 416. It can be done. The controller 309 is a system including a well-known computer as will be described later, and has a register for setting and counting the number of page memories, and a register for setting and counting the number of books. It is shown in Table 1.

[Table] The detailed control operation by the controller 309 will be explained with reference to the sequence control flowchart in FIG. After the power is turned on and the heater of the fuser 426 reaches a predetermined temperature, the reading light source 403 is turned on, the switch 511 of the memory erasing power supply 509 is turned on, and the pulse motor 409 is turned on to move the memory and erase all the contents of the memory. Clear (step 701).
Note that this operation can also be performed immediately after turning on the power. When the memory is moved from one end to the other and cleared, the memory end detection switch 433-2
Turn off the means for clearing (step 207).
In addition, 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 scan count register in the control circuit 413
SBR, page memory area count register MAR,
Clear register CMR for counting the number of books, display drive register MAC, and CMC (step 701)
~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. At this time, when the power supply 508 is activated at the same time, 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. After the storage is completed, the lamp 402 and power source 508 are turned off, the memory board is moved to the right by one frame by the pulse motor 409, and the storage register MAC is set to +1. Then, it is determined whether memory switch MR is turned on (step 706). Thereafter, in the same manner, the required number of originals are sequentially stored in the memory.
After each page of the original has been stored, the memory end switch ME is turned on, and the sequence flow proceeds to step 711, allowing other information to be set. Here, the required number of books is set using the number key CSS and stored in the register CMC. (Reading/Printing) Next, when the start switch CPB is turned on (step 712), the memory reading and recording operations start. The y-axis direction of the memory is controlled by self-scanning by an external clock pulse (not shown) of the CCD411.
It is read by CCD411. The x-axis direction is scanned by the movement of the memory board by the pulse motor 409 and read by the CCD 411 for one bit. 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 read recording starts, the page register is first read.
Set SBR to zero. Then, set the tip of memory area 1 to the memory read 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 chargers 418 and 419, the lamp 420, and the developer 421 are operated to start executing a known electrophotographic process (step 715). The photoreceptor surface charged by the charger 418 is charged by the charger 418
After passing through the surface, the memory read light source 403 is turned on and the first scan in the y-axis direction is performed. The pick-up roller 423 is also turned on to feed one sheet of transfer paper (step 716). Check whether the lamp 403 is on, and if it is not, turn it on.
A laser scanner 414 captures the image formed on the CCD 411 into the CCD memory (step 717) and scans it in the width direction of the photoconductor (from left to right).
The CCD is scanned in the y direction in synchronization with the operation (step 718). Then, a time-series captured electric signal is inputted from the CCD via an amplifier 412 to a semiconductor laser oscillator 415, and the brightness of the laser is modulated according to the magnitude of the captured signal. The laser light carrying the 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 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 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, and x
The memory is advanced by one bit in the axial 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 is stored in advance in the register SBC, for example, 2970 (resolution) for A4. Therefore, when the number in the register SBC matches the number in the previous register SBR, scanning for one frame is completed (step 722). Since the progress has just been made by one bit, the process returns to step 717, starts scanning in the y-axis direction from the initial position again, imports the image information formed on the CCD 411 into the CCD 411, and similarly synchronizes with the laser scanner 414 to start the second line. Record information on a photosensitive drum. By repeating this operation, when the maximum number of scans determined by the register SBC is completed, the process advances 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.
A high contrast electrostatic latent image is formed by irradiating the entire exposed surface with a lamp 420. 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 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 read area (step 723), and the register
The number of MAR is incremented by 1 (step 724), the x-axis scan count register SBR is set to zero (step 725), and the count register MAR and memory register MAC are compared each time reading of one area is completed (step 724). 726), if they do not match, that is, if the recording of all the memories is not completed, the next memory frame is escaped in sequence (step 716), and the same steps as for the first page are performed to feed the recording paper, read the memory, and form the latent image. After that, recording of the second page is completed. 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. Note that the movement of the memory by the pulse motor and the rotation of the photosensitive drum 400 are synchronized. 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 move the memory one bit in the x direction. Thereafter, the book count register CMR is incremented by 1 (step 727). The desired number of books is displayed on the number display.
Since the CMCD is stored in the memory CMC that displays it, it is determined whether the number matches the counter register CMR (step 728).
If they match, step 713 is executed again, and the pulse motor 409 is reversed to return the image memory to its initial position (step 714), and memory reading from memory area 1 is performed again to continue recording. Thereafter, in the same manner, the recording operation is stopped after performing the recording operation 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 the tray 308, the pages are printed in order from the bottom, from the initially read page to the last page, but if the reading from the memory is reversed and the last page is read and printed, the page order can be reversed. I can do it. Although we have explained an example of using optical memory as image memory, semiconductor memory, magnetic disk,
It is clear that similar effects can be obtained using memory media such as magnetic tape. Although the electrophotographic method has been described as an example of a recording method, similar effects can be expected by using an inkjet method, a control method, an electrostatic recording method, etc. in which an ink gun is controlled by the output of a CCD. Further, 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 (μCOM4 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 1R for specifying an arbitrary memory area are provided on the panel 301. When the original image has been stored in the memory as described above (step 707), the numeric keypad CCS is turned on and the area number is entered in the register IR (step 707-
1). It is determined whether the switch 1R is on (step 707-2). If it is on, 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 714-3). When the number of registers IR is 1, the process advances to step 715 as shown in FIG. 5 (steps 714-
4) Start reading and printing from the beginning. When the reading of one page is completed, it is determined whether it is forward or reverse in step 723-1. When the reverse is the case, the memory is moved to the left by 2 frames by the pulse motor, and when it is positive, the memory is moved to the right by 1 frame.
Move the frame (steps 723-2, 3). Thereafter, one book is read and copied in the reverse direction as shown in FIG. 5, and this is repeated to complete the copying of the desired book set using the ten keys. If we now copy from the second page, we set 2 in the initial register IR (step 707-
1). Then, the number of page register MAC is set to -1 (step 707-3). And step 714-1
If it is determined that IR is not 1, it is determined whether it is forward or backward (step 714-5). If positive, move the memory one frame to the right (step 714-6) and register
Subtract 1 from IR (step 714-6). Then, IR becomes 1, so proceed to step 715 and enter the second step.
Start reading and printing from page number. In the opposite case, the IR is set to 1 without moving the memory. Therefore, reading and printing starts from the last page. The number of registers MAC is corrected according to the number of registers IR, so if it is in the forward direction, it will copy from the second item to the last page, and if it is in the reverse direction, it will copy from the end to the second page. . In other words, any desired page can be copied. Note that what is called frame shift in Figures 4 and 10 is to move the length memory including the space between frames, and the control unit 309 counts the power pulses of the pulse motor to a predetermined value and turns off the motor. It can be executed by 2970+ for moving one frame
This is possible with a count of 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, or by detecting the drive pulses and counting the number of detected pulses using a computer. But it is possible. This can also be applied to moving one bit of memory, and also to setting the image memory position by applying a predetermined number of pulses to the ROM,
This can be done by storing it in 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 number of pages, and if you turn on the numeric keypad CSS after turning on SPB, you can copy the original image of only the pages you previously set using the IRS key and numeric keypad CSS to the numeric keypad that was turned on later. Read from memory and print the number of times. i.e. IR from number of register MAC by key IRS
Subtract the amount related to the number and store it in another register MACC. MACC 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 during sequential continuous copying. However, when the single page key SPB is turned on next time, flag S is set and the number of end page register ER is set in the register.
Set to CMC (707-5 to 707-7). Then, the routine jumps and the initial memory location and memory read area are set as described above (714-4). After setting the position and printing out the page as described above, flag S is determined (step 722-2), and since it is a single page copy, step 722-2 branches to step 727 and the number of copies is counted in register CMR. After setting
Compare with CMC (step 728-1). CMR
If it does not match the CMC, the process returns to the routine based on the determination of flag S, and control is performed to read the same page again from the beginning and print it. CMR and CMC
If they match, the process returns to the routine 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. Also, the ERS key in Figure 6 is used to copy between desired pages in the image memory for the desired volume by aligning the pages, turning on the numeric keypad and initial page key IRS in sequence, then turning on the numeric keypad and end page key ERS in sequence. If you turn on the keypad, then turn on the numeric keypad and the copy key CPS in sequence, you can repeat the copy between the number of the first numeric keypad and the number of the second numeric keypad for the number of copies of the third numeric keypad. In other words, after turning on the IRS key and the numeric keypad in sequence, the ERS
Turn on the key and step register MACC 707
It calculates and stores it again according to the number in the register ER, such as -9, and waits for the next numeric keypad or copy key to start copying the number of copies. In other words, if the memory storage page is 10 pages and the copy range is 2 to 9 pages, the register
The number of MACCs will be eight. After the copy key is turned on (712, 713), when the switch FR is turned in the forward direction, it will shift to the right page of the memory (move the memory to the left) until the register IR becomes 1 (714-1)
〜(714-3)〜(714-4)〜(714-6)〜
(714-7). (714-3) sets the memory to the initial position and sets the order flag. After that, as mentioned above, copying automatically starts from the initial page, continues to copy 8 pages in succession, and when one book is finished, the routine starts copying the second book again, and the desired number of books has been copied. The program then proceeds to routine d and waits. When the switch FR is turned in the reverse direction after the copy key is turned on, the frames are 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 (714-1).
〜(714-2)〜(714-8)〜(714-9)〜
(714−10). (714-2) sets the memory to the storage end position and sets the reverse flag. Thereafter, as described above, the pages determined by the register MACC are sequentially copied 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. In addition, 713
clears each register and returns to the initial state for book copying. As described above, it is possible to make multiple copies of only the desired page, and it is also possible to automatically combine the necessary number of copies by sequentially copying from desired page to page. There is no need to add a sorter device for distribution, making it easy to make multiple large-scale copies. Note that canceling the image in the memory can be accomplished by executing the switch 701 by once shutting off the switch SW that turns on the power to the device. Of course, it is also possible to provide an image clearing key and perform the input determination in routine d to proceed to step 701. Also, in this example, if a non-erasable number is stored in advance in the corner of each page 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 written on the copy paper of the reproduced image at the lower right corner. . Also, the above
Considering the case of copying from the middle of the memory by turning on the IRS or ERS key, a lamp is provided on the lens or near the CCD to illuminate the upper right corner of the bar lens (self-setting) 410 corresponding to the number of copies. In the case of a single page copy, the number of pages can be prevented from being reproduced by closing the lamp. FIG. 12 is an example of a circuit diagram when a microcomputer TMS9900 (Texas Instruments) system is used as the controller 309 in FIG.

10D and 511D are relays for turning on and off switches, and each load is connected to the output port of the CPU via such a driver. pulse 4
09 receives a motor on/off signal line and a forward/reverse rotation line from the CPU. FIG. 13 is a flowchart showing an example of a program when performing the control shown in FIG. 4 using TMS9900, and is shown in machine word mode. A microcomputer system generally has a memory ROM that stores programs in machine words, and a memory RAM that inputs and outputs data when executing this program.
This RAM is used for various registers such as MAR and MAC. Command words such as LOCR in the diagram are
Follows the TUS9900 product manual. BL and BLWP are programs that jump to subroutines, and the subroutines execute operations such as steps 717 and 718 that read memory contents into the CCD and output them. The contents of these subroutines can be created by those skilled in the art without any particular problem. An actual program example is shown in Table 2 as an instruction list. You can program it like this. Note that the input port address is the address from 0200H (hexadecimal), and the output port address is the address from 0100H.
