Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an image processing device, and particularly to an image processing device that handles image information stored in a memory. [Prior Art] A conventional device for handling image information stored in a memory has been proposed, for example, in Japanese Patent Laid-Open No. 140542/1983. The device shown in this proposal writes image information of a document over multiple pages in an image memory in a predetermined order, then reads out the written image information in an order different from the order in which it was written, and prints the image information on a recording material such as paper. It has the function of printing and recording. [Problems to be Solved by the Invention] However, in such a device, the readout order of non-consecutive pages among the multiple pages of image information stored in the image memory is set randomly in advance; It is not only possible to sequentially read out multiple pages based on the image memory, but it is also not possible to read out a desired page among multiple pages in the image memory. Therefore, if the user needs print materials for desired multiple pages of image information, the user must manually select the desired print materials after printing all of the image information read from the image memory. It was very difficult to use, and there was a lot of room for improvement. Such room for improvement is not limited to the printing described above, but also occurs when processing a plurality of image information stored in memory. SUMMARY OF THE INVENTION An object of the present invention is to improve this point and provide an image processing device that is easy to use when handling a plurality of pieces of image information stored in a memory.

Another object of the present invention is to provide an image processing device that can be configured. <Means for Solving the Problems> The image processing device of the present invention is an image processing device that handles a memory in which image information is stored in each of a plurality of storage blocks, and the image processing device handles a memory in which image information is stored in each of a plurality of storage blocks. a first instruction means for sequentially instructing multiple selections of arbitrary blocks in a desired order;
a second instruction means for instructing the reproduction order of the plurality of blocks sequentially selected in a desired order by the first instruction means to be the same order as the desired order or the reverse order, by the first instruction means; and means for sequentially reproducing a plurality of non-consecutive blocks sequentially selected in a desired order in the same order or in the reverse order instructed by the second instruction means. <Operation> In the above configuration, a plurality of non-consecutive blocks sequentially selected in a desired order selected by the first instruction means are selected in the same order or in the same order specified by the second instruction means.

[Embodiment] In the embodiment of the present invention described below, a plurality of document images are stored in memory in advance,
Any one document image can be selected and copied from the memory, and in that case, the first

A reading unit 305 includes a photoelectric converter that scans the image memory 304 and reads out image signals. This converts the image signal into a time-series electrical signal. 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 a monovalent book is placed here or at a good time to separate each book. . 309
is a control unit for optimally performing these operations. MR, HE, CSS, and CPB are signals for starting a storage operation in the memory 304, a signal for canceling the storage operation and enabling copying, a number signal indicating the number of books, and a signal for instructing the start of printing.
Each is outputted by the key switch shown in FIG.
MAC and CMC are signals for displaying the number of images stored in each memory 304 and the number of books using the numeric keypad on the panel section. IEX is a signal that controls lighting of the lamp 303 for storing an image in the memory 304, PF is a signal that operates the rollers for feeding paper from the cassette in the copier 307, and RED is a signal that operates the converter 303.

CSS is a setting device for setting the number of recorded volumes using the numeric keypad, MACD is a display that shows the number of records stored in the memory area, and CMCD is a display for displaying the number set by CSS, all of which use a segment display method. 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. 4) is used.

Area 1 of 04 (hereinafter the areas are referred to as pages and frames)
is memorized. 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. Thereafter, in the same manner, original images of up to 10 pages are stored in the image memory. Then, by using the number set key CSS on the panel 301, the required number of books is stored in another memory (register). Then start switch
When the CPB is turned on, reading of an 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. Once finished, if you want more books, return the image memory to its original position and use memory areas 1 and 2.
Read out the books one after another and copy pages 1 to 10 in the same way as the first book. 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. 5-1 is used. The cam plate 309 is a forward/reverse motor 310

Activated by erase signal. 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. Reference numeral 508 is a power source 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.

Turns on. 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 the memory, and detector 41 is a solid state line photodetector called a CCD (Charge Coupled Device).
scanner). This is provided so as to be able to detect an image of one bit (one pixel) in the x-axis direction and the width of the document in the y-axis direction. 406 uses OPC (organic semiconductor photoconductive layer). This makes it possible to increase the light transmittance. Figure 6 shows an example of a CCD. l in the figure is CCD
411 shows the length of the light receiving section. For example, Fair Child
The CCD 121 manufactured by the company has l of 26 mm and 1728 pits in the y direction. In other words, it has 65 pixels per mm. By the way, usually per mm
It can be said that 10 pixels has sufficient resolution for the human eye, so the image formed on the CCD 441 is 1/1 of the original image on the platen 302.
It would be fine if it was 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 impairing the resolving power. The width of the memory 304 is the width of the CCD.
Since it can be made to the same size as 26mm, the memory can be made very small. By the way, the image area of an A4 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 26 mm, which can be stored in the above memory. 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. 7, a large number of pages can be stored and a compact memory can be constructed. By the way, about 300
20 pages can be stored on a mmφ die. In addition, No. 8,
9, 434-1 on the memory plate sets the initial position of the memory to the switch element 433-1.
434-2 is a mark for detecting the memory end in 433-2. 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 which outputs a signal BD (Fig. 1).
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
While moving the two at a speed difference corresponding to the reduction ratio, slit exposure is performed to form an image in the memory. 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 in the x direction during reading. Also, the amount of area movement and pit movement can be determined by the number of drive pulses of the pulse motor.
The memory can be moved to the right along the x-axis by forward rotation of the pulse motor, and to the left by reverse rotation. 43
5 is a support member 437 for supporting the memory and making the memory movable along the guide rail 436;
is a pulley for moving the supporting 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 using a disk memory, it is moved in parallel to the writing section and the reading section before each process starts, rotated when erasing or moving frames, and moved in parallel pits during scan writing and reading. let To explain the operation, 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 is stored once in a buffer memory and then read out in synchronization with the scanning speed of the polygon mirror 416. You can do it like this.
The controller 309 is a system including a well-known computer as described below, and controls the number of page memories,
It has a register for counting 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 fixing device 426 reaches a predetermined temperature, the switch 511 of the reading light source 403 and memory erasing power source 509 is turned on, and the pulse motor 409 is turned on to move the memory and read 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 is moved from one end to the other and cleared, the memory end detection switch 433-2 is activated.
As a result, the means for clearing is turned off (step 702). In addition, in the determination step such as step 702,
N indicates no and 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 SBR and page memory area count register in the control circuit 413
Clear MAR, the register CMR for counting the number of books, and the display drive registers MAC and CMC (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. 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). Alternatively, the image can be stored in the memory by performing slit exposure on the original while moving the document table, lamp, and optical system lens. After memorization is completed, the lamp 402 and power supply 508 are turned off, and the memory board is rotated by the pulse motor 409.
Move the frame to the right, and store the memory register MAC
Add +1 to 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 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 CCD411 is taken into the CCD memory (step
717), the CCD is scanned in the y direction in synchronization with the operation of the laser scanner 414 for scanning in the width direction of the photoreceptor (from left to right) (step 718). Then, a time-series captured electric signal is input from the CCD to a semiconductor laser oscillator 415 via an amplifier 412, and the luminance of the laser is captured and modulated according to the magnitude of the signal. Laser light containing image information is
Deflected in synchronization with CCD y-direction scanning, F-θ
The light is irradiated onto the rotating photosensitive drum surface through a 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, 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, when the number in the register SBC matches the number in the previous register SBR, 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, import the image information formed on the CCD 411 into the CCD 411, and synchronize with the laser scanner 414 in the same way to start the second line. information is recorded on the photosensitive drum. This operation is repeated, and 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 recording in the entire memory is not completed, read out the next memory frame in sequence (step 716), feed the recording paper, read the memory, and form the latent image in the same way as for the first page. 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 CMCD is stored in the memory CMC that displays it, it is determined whether or not the number matches the counter register CMR (step 728).
If they do not match, step 713 is executed again, 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 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. 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. Figure 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 is a control flow diagram for reading and printing from an arbitrary memory area to another area and making copies of a desired number of books. Panel 301 displays switch F/R for forward/reverse selection, switch IR for specifying any memory area, and switch SPB for copying only any area.
Provided for. Each copy mode is (1) forward/reverse mode, (2)
Random single mode and (3) random sorter mode. 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 707-
1). Determine whether the switch IR is on (step 707-2); if it is on, set another register
Reset MACC as in step 707-3.
In other words, subtract the number in register IR from MAC and add +1. Store this in MACC.
In other words, the number of remaining areas, ie, the number of pages from the initial memory page stored in the register IR to the last page of the memory where the image is stored, 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 activated to print in the reverse direction, the memory end position is set to the read position, and the reverse flag is set as data indicating the reverse mode.
Set FLAGR to another memory (714-2).
When 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). If it is determined that the number stored in the register IR indicating the initial address in the forward mode is 1, the process proceeds to step 715 as shown in FIG. 3 (step 714-4), and reading and printing starts 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. After reading one page, 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 normal mode, that is, when FLAGR is reset, the memory is moved one frame to the right (step 723-2). , 3). Furthermore, step 714-8
~714-10 will be described later. Since ER=MAC, the program passes in this example. In addition, if the reverse mode is used and the number of books stored in the number register is plural, when the first page of the memory has been copied, the process goes to step b (step 713) via 728-1.
Return to. Then start copying from the last page again. In this way, 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 numeric keypad. 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. In addition, in step b, a step is executed to determine the input to stop book copying and to change the input.
You can also set it to wait at 711. If a forward mode copy is to be made from the second page, the initial register IR is set to 2 (step 707-1). and page register mac's
The number of stores is decreased by (-1) (step 707-3). Let this be MACC. And step 714-1, 3
Sets the memory to the memory start position (left end) and resets FLAGR. Then, in step 714, it is determined that IR is not 1, the memory is moved one frame to the right (step 714-6), and the register is
Subtract 1 from IR (step 714-7). Then, since IR becomes 1, the process advances to step 715 and starts reading and 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 at the last page. Similarly, 3
When copying from the first page, printing is started after skipping two frames in the memory, and similarly returns to step b at the last page. In the reverse mode, reading and printing starts from the last page by executing steps 714-2 and 715. Since the number of registers MAC has been corrected according to the number of registers IR, it is judged as 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, copies are made from the last page to the second page. In other words, any desired page can be copied. After copying the desired volume or when the number of volumes is 1, the process means is turned on (step 729), registers CMR, IR, MAR, and MACC are cleared (step 730) and the process waits. Also, as described later, it is possible to copy in reverse mode based on the number of stored pages using the ERS key. Note that after executing steps 714-4 and 714-8, the register
Set the initial numbers (based on the key CSS) in IR and ER. The operations shown in FIGS. 2 and 8 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. It is possible to set the number of pulses in ROM or
It is possible to store it in RAM and output that number of pulses from the controller 309 to the motor, or it is also possible to detect drive pulses and count the number of detected pulses with a computer to turn off the motor. It is. This can be applied to the movement of one bit in the memory, and can also be applied to setting the image memory position by storing a predetermined number of pulses for this purpose 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 copying only the desired number of pages, and ERS is a key for copying from the page set by the IRS key to the page set by this key. When the single key SPB is turned on and then the numeric keypad CSS is turned on, the original images of only the pages previously set using the IRS key and the numeric keypad CSS are read out from the memory and printed by the number of numeric keys turned on later. That is, as described above, first, the number in the register IR is subtracted from the number in the register MAC using the key IRS, and the result is stored in another register MACC.
MACC is used for book printing (707-3). Furthermore, if you turn on the numeric keypad CSS again next time,
Store the number in 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 IRS is turned on or after 707-4, the flag S is set, the number of copies is set using the numeric keypad, and the input of the copy key CPB is sensed (from 707-5 to
707-7). The program then jumps to the routine and sets the initial memory location and memory read area as described above (714-4 to 714-7). After the position is set, the flag S after printing one frame of the page to be printed out is determined according to the above-described procedure (step 722-2). If the desired single page multi copy is now desired, the process proceeds to step 727 without executing steps 723 to 726, and increments the 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, the routine returns, and the same page is again read from the beginning and printed. When CMR and CMC match, the process stops, returns to the routine, and waits. If you perform the same key procedure again, you can make a similar copy without canceling the memory image. In other words, by sequentially turning on the numeric keypad CSS, IRS key, and copy key CPB, you can make a single copy of another desired page. You can also make multiple copies of different pages by turning on the numeric keypad, IRS key, numeric keypad, and copy key in sequence. Further, the ERS key shown in FIG. 4 is used to execute copying between desired pages in the image memory for a desired book by aligning the pages. If you turn on the numeric keypad CSS and initial page key IRS in sequence, then turn on the numeric keypad CSS and end page key ERS in sequence, then turn on the numeric keypad and copy key CPB in sequence, the numbers on the first numeric keypad will change from the number on the first numeric keypad to 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. If the forward/reverse key F/R is turned on immediately after the copy key is turned on, even in the above-mentioned reverse mode copying, the desired number of copies between pages can be made in the order of the pages. 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 corrected by the number stored in the register ER as in step key 707-9, and the numerical value is stored again. Start copying the number of copies using the following 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, register MACC
The number of is 8. When the switch FR is turned in the forward direction after the copy key is turned on, the registers are
Shift the memory page to the right page (memory to the left) until IR becomes 1. Copying is then automatically started from that page as described above. step 715
~726, and when the copying of the 9th page (copying 8 pages) is completed, the count number of the register MAR will be
Since it matches MACC, register CMR is incremented (step 727). Copying for 8 pages is continued in sequence, and when copying for one book is completed, copying for the second book is started again from routine b. Register CMC
When the copying of the desired number of books set in is completed, the program proceeds to routine d and waits. After the copy key is turned on and reverse copy is set using the switch FR, the read 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 tore in the register ER is different from the last page, shift frames to the left page of the memory (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~ 714−
Ten). 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 have been copied in the same manner as above, the routine proceeds to routine d, where each register is cleared (step 730) and the process waits. As described above, it is possible to make a single copy or multiple copies of just the desired page, and it is also possible to copy sequentially from the first desired page to the second desired page, and to copy between the desired pages repeatedly for the required number of books. It also becomes possible to perform automatic reconciliation. Further, there is no need to attach a sorter device for distributing copy paper, and it becomes easy to copy a large number of copies in page order. Note that canceling the image in the memory can be accomplished by executing step 701 by once shutting off the switch SW that turns on the power to the device. Of course, a key for clearing the image is provided and its input is judged at the timing of step 730, and then step 701 is performed.
You can also proceed with FIG. 12 is a control flowchart that makes it possible to partially clear and partially change the image memory.
This control can be achieved by inserting this between step 730 and step 707-1 in FIG. In step 800, it is determined whether the erase switch 403 is on. switch 403 to panel 301 (fourth
(Figure). 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 switch 403 is turned on, the number of numeric keypad CSS turned on next is registered as erase page data.
Store in ICR (step 801). Then, a motor is driven to move the memory to that page (802). Then, the erase power supply 511 is turned on and off to clear the image of that page (803). Thereafter, the memory is initialized as in step 705 (804). A document image storage process similar to steps 706-709 can then be performed to store a new image in memory on the cleared page. Thereafter, it waits to receive a read/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. Assume that two copies are made in the normal mode, with the second page as the first page and the ninth page as the second page. As described above, after copying the second page, it is determined whether the forward/reverse flag FLAGR is 1 (step 723-1), and when the forward mode is in effect, it is further determined whether or not the jump mode is in effect (step 901). This is the fourth
A microcomputer determines the state of switch JP, which selects between jump and normal as shown in the figure. When it is normal, copying is executed according to the procedure shown in FIG. When jumping, the memory is shifted to the page location set in register ER. That is, the motor is driven by performing a frame count of -2 and a space count of (MACC - 1) of the number stored in the register MACC. This address control can also be performed by counting the motor drive pulses corresponding to the frames and spaces described above, as described above. Once the second page has been set, the read print step 715 in FIG.
The same operations as steps 722 to 722 are executed (step 902) to finish copying the second page (9th page) and eject it on top of the first copy. Then, the book number counter register CMR is incremented (step 727). Then, the process returns to step 713 again, and the state of the forward/reverse switch F/R is determined. If the forward mode is selected, copies of the second and ninth pages are repeated and ejected as described above. Result counter register CMR
Since it matches the number (2) stored in the register CMC (728-1), it 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 memory is transferred to the 2nd page. Set the address. Then, as described above, reading and printing in step 902 is executed, and 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. Note that one image is scanned and stored in the entire area without providing space in the memory 304.
It is also possible to print out multiple partial copies from the memory 304 by following the steps shown in FIGS. 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, as is clear from the flowcharts of the computer in FIGS. 3, 9, 12, and 13, pre-start by the key CPB is blocked and the operation is prevented while writing a document to the memory and clearing the memory image. are doing. Also, during print 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 image storing operation in the memory 304 by the memory key MR is also prohibited during the printing 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. Furthermore, if a non-erasable number is stored in advance in the corner of each page of the image memory in this embodiment sequentially from the left page, and the number is also read out and printed along with the image,
Pages can be automatically written on the lower right corner of the reproduced image copy paper. In addition, in consideration of copying from the middle of the memory by turning on the IRS or ERS key, a lamp is placed on the lens or on the CCD so as to illuminate the upper right corner of the bar lens (self-offering lens) 410 corresponding to the page number. If the lamp is installed nearby, the number of pages can be prevented from being reproduced by closing the lamp in the case of halfway copying or single page copying. FIG. 10 is an example of a circuit diagram when a microcomputer TMS9900 (Texas Instruments) system is used as the controller 309 in FIG.

A motor on/off signal line and a forward/reverse rotation line are input from the CPU. FIG. 11 is a flowchart showing an example of a program when performing the control shown in FIG. 2 using TMS9900, and is shown in machine word mode. That is, the numerals assigned to each step in FIG. 11 correspond to the numerals assigned to each step in the flowchart shown in FIG. 2 or FIG. 9. In other words, each step in FIG. 11 is a machine word representation of each step shown in FIG. 2 or 9, and the operation is the same as the operation of each step described above. . The microcomputer system has a memory ROM that stores programs in machine words.
In general, there is a memory RAM to which data is input and output when executing this program.
The program shown in Figure 1 is put into the ROM, and various registers MAR, MAC, etc. use this RAM. Command words such as LOCR in the figure are in accordance with the TMS9900 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 anyone 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.
