[Detailed description of the invention]

<Industrial Application Field> The present invention relates to an image processing device, and particularly to a device for processing image information written in a memory. <Prior Art> As an example of a device that processes image information written in a conventional memory, the following device can be cited. That is, in order to obtain multiple copies without circulating the document as is done in the apparatuses shown in FIGS. 1 and 2, image information of the document is once written in memory, A device has been proposed that reads out image information written in the image multiple times. <Problems to be Solved by the Invention> However, in the above-mentioned apparatus, it is difficult to cope with the selection of any one page of desired image information in the memory. Therefore, if one page's worth of image information is damaged for some reason when reading the image information from the memory, a problem arises in that it is difficult to recover it. Furthermore, if the number of pages of document information to be stored is small and it is stored in only a partial area of the memory, if all the areas in the memory where images can be stored are read and output, there is a possibility that blank pages will be output in addition to the image information. Purpose and Structure The present invention eliminates the above-mentioned drawbacks, enables proper sequential reading of the total number of stored pages without manually inputting the total number of stored pages, regardless of the amount of image information stored in the memory, and reads out multiple pages sequentially.

A converter 306 converts a time-series electric signal into a time-series optical signal, and is composed of, for example, a laser light source and a driver circuit (including a modulation and deflection circuit) for the light source. Reference numeral 308 is a tray for storing copies made by the copying machine 307, and it slides when a copy of one book is placed here or at a good time to separate each book. . 3

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 301 (details are shown in Fig. 6) is used. When you press the memory switch MR on the top (shown), the lamp 3
03 to expose the original, and the first page is stored in image memory 3.

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 memory area 2. 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).
to be memorized. 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. The photoreceptor of the 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. After the recording of the first page is completed, the image memory area 2 is read, and the second page is recorded in the same manner, and the recording of up to 10 pages (one book) is completed in the same manner. When the copying process is finished, if more copies are desired, the image memory is returned to its original position and memory areas 1 and 2 are sequentially read out, and pages 1 to 10 are copied in the same manner as the first copy. 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 signal TD from the control unit 309. For example, a tray as shown in FIG. 7-1 is used. The cam plate 309 is a forward/reverse motor 310

Generates a sine wave or square wave voltage of about 100KHz. 508 and 509 apply voltage to the memory via electrodes 405 and 408. 510 and 511 are switches for writing and erasing, and the control unit 309
It is turned on by the write signal WS and erase signal ERS from. 433-1 is a switch for detecting the initial position of the memory 304 and stopping memory movement; for example, it optically detects a mark placed in a non-image area of the memory and turns on. 433-2 is an optical switch that similarly detects the end of memory, and detector 411 is
Solid-state self-scanning photodetector 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 CCD121 made by Manufacturer has a l of 26 mm and a diameter of 172 mm.
It has 8 bits in the y direction. That is, per mm
It has 65-bit pixels. By the way, usually mm
Since it can be said that a pixel with 10 bits per image has sufficient resolution for the human eye, the image formed on the CCD 411 can be reduced to 1/6.5 of the original image on the platen 302. It turns out.
The width of the image stored in the memory 304 can be formed on the CCD 411 at the same magnification via a well-known optical element array 410. Therefore, the resolution of the liquid crystal is
Since it is 40 bits or more, the CCD can read out images without compromising resolution. The width of the memory 304
Since it can be made to 26mm, the same size as CCD l, the memory can be made very small. By the way, A size (290 x 210)
The image area of the book manuscript is usually 250 x 170, so
If this is reduced to 1/6.5, the width will be approximately 26mm, which can be stored in the memory above. Therefore, the length of the memory that can store 10 pages of manuscript is approximately 1mm space.
It will be 400mm. 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 304 can be
In order to store the information in the image, the optical path can be set as shown in the figure. In this case, the platen 302, memory 304
An image is formed in the memory by slit exposure while moving the two at a speed difference according to the reduction ratio. Furthermore, readout lamp 40
3. 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. Also, 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, and 437 is a pulley for moving the support member 435 by the pulse motor 409. It is also possible to provide the pulse motor with a pinion gear and the memory with a rack gear to move the memory in a pinion and rack manner. 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 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 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 of light and shade 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 should 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 70)
1). Note that this operation can also be performed immediately after turning on the power. When the memory has been moved from one end to the other and has been cleared, the memory end detection switch 433-2 turns off the means for clearing (step 207). In the determination steps such as step 702, N indicates no and Y indicates yes. Upon completion of memory erasure, the lamp 403, power supply 511, and motor 409
After turning off the control circuit 413, clear the scan count register SBR, page memory area count register MAR, register CMR for counting the number of books, and display drive registers MAC and CMC (steps 701 to 704), and then clear the memory. Return to starting position and set (step 70)
5). In other words, 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 advances 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, the leading end of memory area 1 is set at the memory read position (step 71).
4). 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 transferred to the charger 41
After passing through the surface No. 8, the memory reading light source 403 is turned on to perform the first scan in the y-axis direction. The pick-up 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 scanned 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). (Step 7)
18). 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 to advance the memory by one bit in the x-axis direction (step 720). And register SBR +1
Then, 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, the number of registers SBC is the first register
When the number matches the number of SBRs, 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 again from the initial position, and scans the CCD 41.
The image information formed on 1 is taken into the CCD 411,
Similarly, information on the second line is recorded on the photosensitive drum in synchronization with the laser scanner 414. 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 readout area (step 723), and the number of register MAR is incremented by 1 (step 724), and the x-axis scanning count described above is performed. The 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 726). If they do not match, that is, if recording of the entire memory is not completed. Escape the next memory frame in sequence (Step 1)
6) In the same manner as for the first page, the recording of the second page is completed through feeding the recording paper, reading the memory, and forming a latent image. 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 72).
8) If they match, step 713 is executed again, and the pulse motor 409 is reversed to return the image memory to the 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 is 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 7).
07-1). 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). register
If the number of IRs is 1, proceed to step 71 as shown in Figure 5.
Proceed to step 5 (step 714-4) and read from the beginning.
Start printing. When reading of one page is completed, forward or reverse is determined in step 723-1. When the opposite is true,
The memory is moved to the left by two frames by the pulse motor, and when positive, it is moved by one frame to the right (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 decremented by 1 (step 707-3). And step 71
If it is determined in step 4-1 that IR is not 1, it is determined whether it is forward or reverse (step 714-5). If positive, move the memory one frame to the right (step 714-
6), -1 from register IR (step 714)
-6). Then, since IR becomes 1, the process advances to step 715 and starts reading and printing from the second page. In the opposite case, set IR to 1 without moving memory.
I end up making it. 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 printing7
07-3. Then turn on the numeric keypad again and register
Store the number in 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.
707-5 to 707-7 set to CMC. The program then jumps to the routine and sets the initial memory location and memory read area as described above 714-4. After setting the position and linting out the page as described above, flag S is determined (step 722-2), and since it is a single page copy,
The process branches from step 722-2 to step 727, counts the number of copies in register CMR, and
Compare with CMC after setting (step 728-
1). Flag S when CMR does not match CMC
The process returns to the routine based on this judgment, and control is performed to read the same page again from the beginning and print it.
When CMR and CMC match, the routine returns via flag S determination and waits. Step 7 again
If the same key procedure as described above is performed to execute the flow after 07-1, the same copying can be performed without canceling the memory image. Therefore, even if the image information read from the memory is lost due to some reason, such as the operating state of the means for reading the image information from the memory or the transmission path of the read information, the memory will retain the information previously read. The information remains without being canceled and can be read out as needed. 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. That is, after turning on the IRS key and the numeric keypad in sequence, the ERS
When the key is turned on, the register MACC is set to step 7.
As shown in 07-9, it is calculated and stored again based on the number in the register ER, and it waits for the next numeric keypad and copy key to start copying the number of copies. In other words, the memory storage page is
Assuming that there are 10 pages and the copy range is 2 to 9 pages, the number of registers MACC is 8. 712,713 switch FR after copy key on
714-- When in the forward direction, the memory is shifted to the right page (memory is moved to the left) until the register IR becomes 1.
1~714-3~714-4~714-6~71
4-7.714-3 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 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 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. Note that 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 clear 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. Figure 12 is an example of a circuit diagram when a microcomputer TMS9900 (Texas Instruments) system is used as the controller 309 in Figure 4, and 402, 403, 510, 511, etc. are the same as in Figure 4 and are the output loads. Yes, 402D, 403
D is a well-known driver circuit for lighting a lamp, 510D and 511D are relays for turning on and off switches, and each load is connected to the output port of the CPU through such a driver. The pulse 409 receives a motor on/off signal line and a forward/reverse rotation line from the CPU. FIG. 13 is a flow chart 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, including steps 717 and 71.
As shown in 8, the subroutine executes the operation of reading the memory contents into the CCD and the operation of outputting 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. Please set the input port address to 0200H.
(Hex/Decimal) and the output port address is the address from 0100H.
