Abstract

PURPOSE:To increase repertory items of copying and to reduce mis-copying by switching either the operation of discharge of an original or the operation of carrying it to an image forming process after the original is read. CONSTITUTION:An 'original copy key' 'one time' 'flag' is turned on when an original copy key 800 in an effective state is depressed and turned off when the key is detached. Since the flag is turned on at the depression of the first key 800 and an original copy indication extinguishes, the indication is lighted and a changeover claw 613 of an automatic draft feeder 601 is switched and an original is carried on a copying machine. In this state, when the key 800 is again depressed, since the indication is lighted, the display extinguishes this time and the changeover claw 613 is switched and the original is discharged to the outside of the ADF 601. After the end of reading of the original, the changeover claw 613 is switched and the original is discharged or carried on the copying machine. Thus, 2nd copy is made from the original or a synthesized copy is attained, repertory items of copying are increased and the operator recognizes clearly the operating mode, then mis-copying is reduced.

It has a second scan cleaner that moves in accordance with. An original (not shown) on the contact glass 9 is optically scanned by the first scanner and the second scanner, and a reflected image thereof is guided to the lens 7 via the color filter 6 and then on the one-dimensional solid-state image pickup device 8. Image.

As the light source 3, a fluorescent lamp, a halogen lamp or the like is used. In this embodiment, one light source 3
The reflector 1 is attached to the
May be used. Since the solid-state image sensor 8 has a constant sampling clock, the fluorescent lamp will adversely affect the image unless it is lit at a higher frequency.

The solid-state image sensor 8 is generally C
CD is used. Since the image signal read by the solid-state image sensor 8 is an analog value, it is analog / digital (A / D) converted, and various image processings (binarization, multi-value conversion, gradation processing, Magnification processing, editing processing, etc.) is performed and converted into a digital signal as a set of spots.

Further, there is a case where a color original is read using a 3-line CCD or the like in order to obtain three pieces of RGB information at the same time.

[Regarding Writing Unit] The image information after the image processing is written on the photoconductor drum 40 in the form of a set of light spots by raster scanning of laser light in the optical writing unit.

As shown in FIGS. 2A and 2B, the laser light emitted from the semiconductor laser 20 is converted into a parallel light flux by the collimator lens 21 and shaped into a constant light flux by the aperture 32. The shaped laser light enters the polygon mirror 24 in a form compressed by the first cylinder lens 22 in the sub-scanning direction. The polygon mirror 24 has an accurate polygonal shape and is rotated by a polygon motor 25 in a fixed direction at a fixed speed. This rotation speed is determined by the rotation speed of the photosensitive drum 40, the writing density, and the number of faces of the polygon mirror 24.

The reflected light of the laser light incident on the polygon mirror 24 is deflected by the rotation of the polygon mirror 24. The deflected laser light is reflected by the fθ lens 26a,

In this case, the image signal from the outside is 1 bit,
In the case of 4 bits, it is necessary to perform a process of converting into 8 bits data.

FIG. 7 is a block diagram of the image scanner. The analog image signal output from the CCD image sensor 107 is amplified and light amount corrected by the signal processing circuit 151 inside the image preprocessor (IPP), and A /
It is converted into a digital multilevel signal by the D converter 152. This signal is subjected to correction processing by the shading correction circuit 153, and the image processing unit (hereinafter referred to as I

SYNC is almost the same signal as the main scanning synchronization signal PMSYNC output from the beam sensor of the image writing unit, but is output in synchronization with the image synchronization clock pulse CLK. The main scanning effective period signal LGATE becomes the high level H at the timing when it is considered that the output data DATA0 to DATA7 are effective images.

In this example, the CCD image sensor 1

The sub-scanning effective period signal FGATE is set to the high level H. This signal FGATE becomes low level L after the time required to scan the maximum reading length (in this example, the size A size in the longitudinal direction) in the sub-scanning direction after being set to high level H.

FIG. 10 is a block diagram of the memory system. An image signal from the photo sensor (CCD) 410 is output as 8-bit data through an image preprocessor (IPP) 411 having functions of shading correction, black level correction, and light amount correction. This data is selected by the multiplexer 1 (MUX1) 412, and the spatial frequency high-frequency emphasis (MTF correction) function, speed conversion function (magnification), γ conversion function, data depth conversion function (8bit / 4bit / 1bit conversion) Is processed by IPU413 and has MUX (3)

In a system having a frame memory for image data, the image data from the IPU 420 is temporarily stored in the memory device (MEM) 421 as shown in FIG.
When necessary, it is taken out from the memory device (MEM) 421 and outputted to the printer (PR). Also,
It is also common to output the image data from the IPU to the printer (PR) and at the same time store it in the memory device (MEM) and copy the second and subsequent sheets with the image data from the memory device (MEM). .

The present device is configured so that the data flow shown in FIG. 12 is possible so that both processed data and raw data from the IPU can be taken into the memory device. That is, the three multiplexers (MUXs) in FIG.
(1) 412, MUX (2) 414, MUX (3) 41
The data flow can be changed by switching 6). For example, one scan scan scans multiple I
When outputting a copy in which the parameters of the PU 413 are changed, it can be achieved by the following procedure.

During scanning, the MUX (1) 412 is set to A, the MUX (2) 414 is set to B, and the MUX (3) 41 is set.
6 is set to A and the first sheet is output. At this time, the raw data is M

For the second and subsequent sheets, the MUX (1) 412 is set to B, and the data from the memory device (MEM) 415 is set to IP.
The data is input to U413 and output to the printer (PR) through MUX (3) 416. At this time, every time one copy is made, the IP
Change the U parameter.

This can be realized in this way.

When holding compact data such as 1-bit data, the MUX (2) 414 is set to A and the output of the IPU 413 is taken into the memory device 415.
In this case, the printer device PR switches to the binary data (1 bit) mode for copying. EXTIN, E in FIG.
XTOUT is an image data input signal from the outside and an output signal to the outside.

In FIG. 13, the compressor (COMP) 440 and the decompressor (EXP) 442 are connected to a memory unit (Memory Uni).

460 is arranged outside the memory unit 462. The function of the PPU 460 is to perform a logical operation between image data (for example, AND, OR, EXO
(R, NOT), the memory output data and the input data can be calculated and output to the printer, and the memory output and the input data (for example, scan data) can be calculated and stored again in the memory unit 462. . The output destination printer and the memory unit 462 are switched by the MUX (6) 461 and MUX (7) 463. This function is generally used for image synthesis, and is used, for example, to place overlay data in the memory unit 462 and overlay the scanner data with the overlay.

The APL (1) 740 shown in FIG. 18 is configured to store image data using an external storage device. When the image data is stored in the floppy disk, it is output from the EXTOUT of FIG. 10 to the floppy disk controller (FDC) controlled by the SCSI controller 711 through the interface (I / F), and the floppy disk drive (FDD) 712 is output.

In the memory unit 471, the data and the image data which are compressed at the same time as the scanning is input into the memory unit 471. The incoming data is stored in different memory areas, but the compressed data is directly entered into the decompressor (EXP) 473 and decompressed. If the processing time of the compressor (COMP) 470 and the decompressor (EXP) 473 is completed normally in time before all the data of one page is stored in the memory unit 471, only the memory area of the compressed data remains and the raw data is stored. The data area is canceled. If the error detection circuit (Error Detect) 474 detects an error signal from the compressor (COMP) 470 or the decompressor (EXP) 473, the compressed data area is immediately canceled and raw data is adopted.

The I / F 701 is used to connect to the system bus via the SCI (serial communication interface).

The page memory 703 is 1 in A3 in this example.
It has the size of a page and converts it into a BIT image here, and at the same time the data speed between the memory unit 716 and the CPU.
It also arbitrates the processing speed of.

The rotation control 706 is, for example, facsimile transmission, and when the original to be sent is A4 vertical and the receiver is A4 horizontal, the sending side automatically reduces by 71% and the sending side becomes difficult to see. In order to prevent this, when the size is the above, the transmission original is rotated by 90 degrees to be converted into A4 landscape and transmitted at the same size. Another purpose is that when receiving and outputting, when the receiving size is A4 landscape and the cassette size is A4 portrait, the rotation control unit rotates the output image by 90 degrees and converts it to A4 portrait and outputs it. This eliminates the need to distinguish between vertical and horizontal cassettes.

[Regarding APL (3) 760] The APL (3) 760 has a function of comparing an image read by the scanner with an image stored in advance, which is an embodiment of the present invention and will be described in detail later.

(Explanation of Fax Operation) The operation of facsimile (hereinafter referred to as FAX) will be described.

This FAX has the functions of MF, G2, G3 and G4, and the transmission density is 3.85, 7.7, 15.4 lines / m.
m, and 200, 240, 300, 40 for G4
It can support 0 dpi and use the scaling function to perform density conversion with each other.

Further, by using the SAF memory 754, memory transmission / reception, relay, confidential reception, polling, etc. can be realized, and further, memory transmission, memory reception, reception output, etc. can be performed at the same time while storing transmission documents in the memory. .

First, the transmission operation will be described. APL (2) 7 by setting the original and pressing the start key
The other party in the RAM 752 of 50 is dialed to call the other party. When it is known that the other party is a FAX, the document reading operation starts. If the start key is pressed when there is no document, a display prompting the document to be reset is displayed.

When the original reading operation is started, the scanner operates to read the original, and this signal enters the engine I / F of FIG. 18 and is stored in the page memory 703 in accordance with the bit size of the page memory 703. EXTOU
T is sent in a multi-value of 8 bits per pixel, whereas the page memory 703 corresponds to 16 bits,
The bit configuration is different, so adjust it here.

The data from the scan scanner is stored in the page memory 70.
When entering 3, APL (2) 7 while compressing this data
It is accumulated in the SAF memory 754 of 50. In this way, the following characteristics are obtained by transmitting the data from the scanna while accumulating it in the SAF 754.

In other words, the reading from Sukiyana is A4
One size can be read in about 2 seconds. In contrast,
The transmission time for G3 is about 9 seconds for A4 size. In this way, the transmission time is about 4.5 times longer than the reading time. By the way, in an apparatus that can be used in combination with a copying machine, a fax machine, a printer, etc. like the example of the present invention, for example, when the next person wants to make a copy during fax transmission, he wants to finish the fax transmission job quickly. . However, the FAX transmission may be sent faster or slower depending on the performance of the partner machine. As in this example, the read data is SA
By transmitting while accumulating in F754, the apparent transmission speed can be increased. In addition, the transmitted document is SAF
Since the data is stored in the memory 754, an image can be correctly sent by retransmitting or calling again when an error occurs during transmission, when the line is disconnected, or the like. In this way, SAF
The data stored in 754 is transferred to G3 via the system bus.
It can be accessed from either the fax or G4 fax unit.

Next, the reception of image information will be described.

In FIG. 20, the received image data is converted into a digital signal by the modem. This is converted into raw data via DCR, further compressed and stored in the SAF memory.

At this time, the reason why the DCR restores the raw data and then compresses it again is that the received data usually contains an error on the line, and if it is stored in the SAF as it is, it may be a hardware error or a data error. This is because the distinction between

When recompressing, a method with good memory efficiency is adopted.

The data stored in the SAF memory 754 is printed out for each page. (1 depending on the mode setting
It is possible to output after accumulating the files) SAF
In order to output from the memory 754, it is necessary that the page memory 703 of FIG. 18 is not used by another APL and that a copying machine is also available.

When these conditions are met, the SAF memory 754
Data is expanded to page memory while being restored to raw data via CEP.

After the development is completed, the optimum paper size is selected. At this time, the data in the page memory 703 is A4 portrait, and when the optimum paper is A4 landscape, the data in the page memory 703 is rotated 90 degrees by the rotation control to be output to the selected paper.

With this function, it is possible to prevent the A4 portrait image from being printed on the A4 landscape paper and to have a margin.

This function is used not only for receiving output but also for reading the image information read according to the partner in the transmission mode.
Since it can be rotated once, for example, when the transmission original is A4 landscape and the receiving side is A4 portrait, it has been sent at 71% reduction until now.
By incorporating the degree rotation, it becomes possible to send at the same size and it becomes easier to see on the receiving side.

Here, instead of the SAF memory 754, H
When using the DD 713, it is possible to set the SAF memory 754 to a buffer and drive the HDD 713 via the SCSI interface of the APL (1) 740. The basic operation of the FAX has been described above.

0 indicates the home position of the check unit 1620.

In an embodiment having such a structure,
When the staple mode is started, first, the drive belt 1717 shown in FIG. 38 transfers the stapler 1701 and the sheet pulling device 1615 toward the predetermined bin 1350 for accumulating the copy sheet stack P on which the staples are to be driven, and FIG. Is stopped at a position close to a predetermined bin 1350 based on a signal from the position sensor 1727. At this time, the solenoid 1626 is off, and accordingly both swing levers 1622 and 1624 and the chuck 162 are connected.
3, 1625 are in the released state. In addition, the bin-fence motor 1462 is turned on and the bin-fence 1460 is released together with the above operation.

Next, the stepping motor 1646 rotates by a predetermined amount to move the timing belt 1643 to move the chuck portion 1620 toward the copy sheet bundle P.

When the chucks 1623 and 1625 are moved to the position where the copy sheet bundle P can be grabbed (FIG. 44), they are stopped there and at the same time, the solenoid 1626 is turned on. When the solenoid 1626 is turned on, the chucks 1623 and 1625 are closed as shown in FIG. 43, and the end edge portion of the copy sheet bundle P is grasped by the chucks 1623 and 1625.

Next, by the reverse rotation of the stepping motor 1646, the chuck portion 1620 is moved to the original position as shown in FIG. 45 while holding the copy sheet bundle P, whereby the copy sheet bundle P is almost horizontal. It is moved in parallel in the direction and pulled toward the stapler 1701 side. When the edge portion of the bundle of copy paper P is transported to a position where stapling is possible, it is stopped there. Based on the horizontal movement amount of the copy sheet bundle P, it is possible to determine at which position of the edge portion of the copy sheet bundle P the staple is to be performed.

After that, the stapler 1701 drives the staple to a predetermined position on the edge of the copy sheet bundle P.

When the stapling operation is completed, the stepping motor 1646 rotates in the forward direction, the chuck portion 1620 advances, the stapled copy paper stack P is returned to the bin 1350, and then the solenoid 1626 is turned off. As a result, the upper 1623 and lower 162 ports that were closed until now
5 will open. After that, the reverse rotation of the stepping motor 1646 causes the chuck portion 1620 to retreat to a predetermined position. After that, the stapler 1701 and the sheet drawing device 1615 are moved toward the next bin 1350, and the stapling operation similar to the above-described operation is repeatedly executed here.

When the stapling is performed on all the bundles of copy paper P, the stapler 1701 is raised and returned to the uppermost home position.

FIG. 50 is a schematic view of the stapler unit 1701.

In this stapler, when the motor 1900 is turned on by an electric signal input from the outside, the staple 1902 in the cartridge 1901 is pushed and bent. The staples 1902 are connected to each other in a strip shape by a thin tape, and are rolled into the cartridge 1901. Further, the last end of the staple needle bundle 1902 passes a near-end sensor (optically reading reflective sensor) 1903 to output a near-end signal.

By the above-described operation, the copy sheet bundle P
However, in the present embodiment, it is possible to further select whether to staple the copy sheet bundle P from above or to staple the copy sheet bundle from below. A stapler 1701 is centered around the Y-axis shown in FIG.
Is rotatable by 180 degrees, and is rotated by a control signal of a copying machine described later. By such an operation,
Whether the bundle of copy sheets discharged from the copying machine is discharged face-up or on the back side, staples can always be driven from the front side of the bundle of copy paper.

[Explanation of Operation of AI Unit] Generally, there is an OCR technology or the like as a method for performing character recognition with high accuracy.
In other words, it is a method of cutting out one character or one character in each original, patternizing the character, comparing the feature of the pattern with the character pattern information stored in the database, and determining the character. Techniques of Nieuro and Fuzzy are often used to determine the characters. Since the original is placed upside down, etc., the character pattern read and cut out is rotated and collated to determine the character.

In the digital copying machine which is an example of the present invention,
Character recognition and comparison are performed by the AI unit (APL (3) 760) in the application. The CPU on the application baseboard performs a process of cutting out a character in an arbitrary character example on the page memory 830 in which image data for one page is stored (preprocessing unit 831), and The AI unit performs the recognition and the comparison (processing of the recognition result).

FIG. 19 shows an example of the hardware configuration for implementing the above-mentioned character recognition and comparison (processing of recognition results) method. The AI unit is for recognizing and comparing the character information cut out from the page memory (image data) 830 on the application. The CPU 784, ROM 785, R
AM786, area memory 782 that handles cut-out characters, comparison results, DPRA that handles commands and responses with the application baseboard, etc.
M781, an image code storage unit (RAM) 787 for storing the recognition result, a pattern generator 789 for generating an arbitrary pattern, and a database (dictionary) 783 used for recognition.

The operation of the AI unit is shown in FIG.
2, the area memory 782 for handling character images, the character recognition unit 833 for character recognition, and the character comparison unit 836 for comparing the recognized characters and performing various processes from the comparison result. It is divided into

In FIG. 19, the character recognition is performed by collating the characters in the area memory 782 with the CPU 784 of the AI unit against the dictionary (database) 783 and outputting it as an image code.
Since many recognition methods such as No. 4 and the like are devised and known, detailed description thereof will be omitted in this embodiment.

The character comparison unit 836 reads the recognition result from the image code storage unit 835 and reads out the image code to be compared with the image code serving as the reference for comparison.
37, an image code comparing unit 838 for comparing the coincidence and non-coincidence of the image code, a comparison result operation unit 839 for counting the coincidence portion and multiplying an arbitrary numerical value corresponding to each coincidence portion, for the comparison result and the operation result The comparison result conversion unit 840 that searches for the pattern to be output and outputs the pattern to the area memory 842.

For example, FIG. 23 shows an example of two correct answer originals A and B as a reference for comparison, and FIG. 25 shows an example of answer originals to be compared with the originals. The grading mode is selected by the operation unit, the setting mode of the LCD touch panel is selected, the correct answer document of FIG. 23 is placed on the editor 202, and the area designation data is set. An example of the editor is shown in FIG. 24 (the usage of the editor has been described in the description of the editor, and therefore the description is omitted for the description of the editor). Stylus pen 9 on the Edeta 202
An area (a portion surrounded by a dotted line) is designated by pressing a designated point in the figure with 00, and then the area processing type of the area is inputted by the mode key. 24. When the setting of the correct answer document A in FIG. 24 is completed, the end key 861 of the editor 202 is pressed to send the setting data to the main CPU 205 or the CPU 710 of the base unit 700 of the application, and the correct answer document B is set. Also performs the same operation. In the designated area of the correct answer manuscript A, the processing type of the part written as “Sansuu” followed by “1” is designated as manuscript recognition 1 and 2, and the information is stored in the common area in the RAM 763 of the application (3) 760. To be done. The process type of the part written as "total" is result printing, and is a part for printing the output of the document recognition and comparison calculation results of FIGS. 23 and 25. The processing types of the portions marked with "*" (two locations) are ID1 and ID2 in FIG.
It is used to determine the ID of the answer document A. Further, the processing types of the other designated areas of the correct answer document A of FIG. 24 are compared, and the processing data numbers are sequentially 1, 2, and 3 from the top. In addition, “(10)” or “(2
“0)” is the processing ratio of the area and is input with the numeric keypad during editing. In the correct answer document B, the processing type of the part marked “@” is a comment and a comment corresponding to the comparison calculation result. The "Sansuu" and "2" portions on the upper left of the original are designated as the common area as the area for performing the original recognition between a plurality of originals in the correct original A.
Cannot be specified. When the above areas of the correct answer originals A and B are compared, both of the original document recognition 1 are “Sansuu” and the original document recognition 2
Is "1" and "2", the originals A and B are two sheets 1
It is judged as a group, and the result print and comment output are 2 with the same ID.
It is output from the result of adding sheets.

In the case of the answer originals A and B shown in FIG. 25, ID1 is "12" and ID2 is "Kimura Akira", and the data of the comparison operation is processed as a set of two sheets. First, the image code storage unit 835, which stores the character recognition result, reads the image code of the correct original and the answer original of the same original type and in the same designated area (image code reading unit 837). Next, the two codes are compared to determine the matching portion and the non-matching portion, and the comparison result is stored in the RAM (image code comparing unit 838). However, if the character strings do not match within one area, they are not matched. For example, in the case of "Kimura Akira," questions (b), (c), and (e) match,
(A) and (d) do not match. On the RAM, the coincident portion is determined to be a correct answer, 01H, the non-matching portion is determined to be an incorrect answer, and 00H is written. Next, the processing ratio of the same designated area as the comparison result on the RAM is multiplied for each designated area and totaled (comparison result calculation unit 839). "Kimura Akira"
You get 60 points. Further, by displaying the score on the display unit (LCD) of the operation unit at the end of counting, the result can be known on the operation unit. If the comment output with the total score of 50 to 70 is set as “well done” by the input from the operation unit, the comparison result is 01.
When H, a pattern corresponding to 01 (for example, "○"), 0
A pattern corresponding to 00H when it is 0H (for example, "x")
And the total score and the comment corresponding to the total score are called from the pattern generation device 789 (comparison result conversion unit).

By the above operation, the pattern converted by the AI unit is output to the base unit 700 of the application through the area memory 784, and the area information and ID of the pattern are output.
Data such as total points is output to the base unit 700 of the application through the DPRAM 781. App base 700
Calculates the write address of the pattern on the page memory 830 based on the area information received through the DPRAM 781, and writes the pattern of the area memory 782 to the page memory 830. FIG. 26 shows a page memory writing result in the case of the answer document shown in this example. App section C
If the PU wants to print only the pattern on the answer manuscript,
When only the pattern is output to the memory system 844 of the copying machine main body and the answer document is for reading the image and the result is to be output on a blank sheet, the answer document image and the pattern are combined on the page memory, and the result is stored in the memory system 844.

The second screen of the scoring mode (execution) as shown in (c) is displayed. This execution mode cannot be selected when the image corresponding to the correct answer document is not stored in the setting mode. By selecting this output destination, a setting screen for execution corresponding to each output destination is displayed, and by making various settings, the process can be executed by pressing the start key. This is the end of the explanation of the outline of the operation unit.

Next, the structure for printing by switching colors according to the pattern of the comparison result will be described.

In this description, changing the pattern output from the pattern generating means to the color of the read original image will be described.

As described above, the developing section of the copying apparatus according to the present invention is provided with two developing devices, one containing black toner and the other containing color toner. The developing device is configured to be switched according to the copy mode to perform development. Further, since the copying apparatus according to the present invention is provided with the multiple copy function, the first copying is performed with the black toner, the transfer paper after fixing is passed through the re-feeding loop 72 (FIG. 1), and the registration roller is again used. Lead to 2
By using the color toner for the second copy, the copy using the two-color toner can be completed relatively easily.

Therefore, in the present invention, the data generated by the character comparison unit 836 shown in the block diagram of FIG.

It is conveyed to the roller 628.

The intermediate document rollers 625 to 626 and the intermediate transfer sheet roller 627 are connected to the original sheet 6 by the transfer sheet detector 633.
The drive is stopped after a lapse of an arbitrary time after detecting 32. At this time, the switching claw 613 is in the position shown by the broken line in the figure.

Further, the transport path shield plate 637 shuts off the transport path inside the copying machine when the ADF is not mounted, and when the ADF is mounted and the ADF is far from the contact glass 631 of the copying machine, the above-mentioned transport path is carried out. It is designed to block the road.

Next, a detailed description will be given of the copying machine main body side which conveys the original document 632 which has been read in FIG.

In the optical unit 638 of the copying machine main body 602, document conveying guide plates 616 and 617 and a document intermediate roller 625 are provided. Document transport guide plate 61

The position of the intermediate document roller 625 is set to the ADF 6
The distance between the document transport roller 614 of No. 01 and the intermediate document roller 625 is shorter than the length of the document size of the ADF 601 in the transport direction of the document size that can be passed.

Further, document transport guide plates 618, 619, 620 in the image transport unit 639 are arranged so that the document is transported to the transfer sheet intermediate roller 627. In the document intermediate roller 626, the document intermediate roller 625, the document intermediate roller 626, the document intermediate roller 626, and the transfer sheet intermediate roller 627 are spaced apart from each other by a distance shorter than the length of the ADF 601 in the transport direction of the document size that can be passed. It is said.

The operation of the switching claw 613 of the ADF 601 of FIG. 89 will be described below with reference to the flow chart of FIG.

First, a check is made as to whether or not the copying apparatus is in a standby state in which a copying operation can be performed (S9201). If it is in the standby state (YES in S9201), the original is set in the ADF 601 of the next step. Check whether the squid or not (S9202). If the document is set (YES in S9202), the next step of the document copy key 800 (FIG. 21) is checked (S9203), and if the key 800 is pressed (YES in S9203).
In S), the next step "Original copy key once" flag is checked (S9204).

This "original copy key once" flag is turned on when the original copy key 800 is pressed in a valid state and turned off when the original key is released, as described in this flow chart. Natsu (S920
9).

Therefore, when the first key 800 is pressed (S92
In (05), the “Original copy key once” flag is turned on and the original copy display (L on the key 800 in FIG. 21) is displayed.
Since the ED800a display is also turned off (S9206)
No), the display is turned on (S9207), and the ADF
The switching claw 613 of 601 is switched so that the document is conveyed to the copying machine side (the position shown by the broken line of the switching claw 613 in FIG. 89) (S9208).

When the key 800 is pressed again,
Since the display is lit (YES in S9206),
This time, the display is turned off (S9210), and A
The switching claw 613 of the DF 601 is switched so that the document is discharged to the outside of the ADF 601 (the position shown by the solid line of the switching claw 613 in FIG. 89) (S9211).

The flow chart in FIG. 90 is an example, and the switching claw 613 of the ADF 601 may be switched according to the state of the document copy display when the document is discharged.

Unlike conventional type OCR technology,
Character recognition is very difficult for image input such as handwriting. For example, when comparing the print type and handwriting, the print type can be recognized if the size is within a certain range. However,
Characters such as Gothic type and Mincho type can be recognized by AI etc., but emphasis (bold type) and italic type, italic type used in word processors, etc.
It becomes difficult to recognize when the inside is doubled, inverted, doubled horizontally, and doubled vertically.

When handwritten, there are unlimited combinations of character size, inclination, circled hand, etc. depending on the individual.

Therefore, in most cases, the postal code of the postcard is compared and only that part is compared by designating the range.
The present invention will be briefly described with an example.

In FIG. 94, for a certain test, (a) is an example of a question manuscript, (b) is an example in which the correct answer for that test is entered by the questioner, and (a) of FIG.
(B) is the answer manuscript of the respondent.

FIG. 96 shows an example of a display device and an input device.

First, the operator sets the correct answer document on the ADF or the like and causes the input device (FIG. 96 (d)) to execute it. The image information read by Sukiyana is displayed on the main display section (Fig. 96 (a)) of the display device as an image of the correct answer manuscript.
A menu display is displayed on the sub display unit (FIG. 96 (c)).

Next, the operator selects an area instruction and uses an input device (not shown) such as a mouse (see FIG. 97 (a),
After picking the start point and picking the end point as shown in (b) and (c), the area is designated. The area of the designated area is flushed and an area number is assigned. However, this number is tentative and can be reconfigured by means not described later.

When the area number is assigned, the pattern to be compared next is selected. If the comparison mode is not entered here, letters, (large and small) numbers, special symbols (Fig. 98 (d)),
Compare in the order of kanji. Limit to numbers here.

Similarly, after inputting (1) and (9), the operator selects the print mode and designates the area as described above. After specifying, select the print mode.

After designating the area (10), the print pattern is designated (FIG. 98 (d)).

For example, when "1" is designated, designated pattern + scoring is selected, and then a designated pattern (not shown) (here, "total") is selected, and then sub-display (5) (FIG. 98 (c)). The screen changes and the print color is selected. After completing the series of settings, the sub display screen is (4) (Fig. 98 (d)).
become.

Next, after selecting the area (11), the print pattern is similarly designated. Here, it is assumed that “2” is selected and the print color is selected as red. When the area designation and the printing condition are determined, the area of the image data of the correct original is designated as shown in FIG. 99 (a), the contents of (4) to (9) are recognized and stored in the database.

Next, the operator sets the answer document on the ADF or the like, selects the scoring mode and executes it.

The answer originals are read one by one by scanning, and only the area data of FIG. 99 (b) are compared.

First, the data comparison of (1) and (2) is performed. As described above, since the numerical mode is set in this area, only the comparison of "0-9" is required, and the recognition time Can be shortened.

Next, the area (3) is recognized and the name of the respondent is recognized. If the database can be switched to an individual base when the name is known, the recognition time and recognition probability will be improved.

Handwritten characters have a variety of character characteristics for each individual, and if the individual's character is input in advance and a personal database is created (for example, the answer written in the national language is directly used as the personal database), The probability is high.

Next, recognition of (4) to (9) is performed, and the results are compared with the above-mentioned correct answer.
In (b)), correct / wrong printing, and correct answer etc. (comment) are printed. Further, this answer document is displayed on the sub-display section of the display device, and "total + scoring" is printed after the scoring is completed.

After scoring, if there is a comment or the like, it is printed in a certain area by another input device (word processor or the like) not shown.

The above may be printed on the answer document by a printing device (not shown). At the time of recording, by masking the question original, the correct answer original, and the answer original shown in FIG. 94A, the data amount can be reduced as shown in FIG.

According to the system configuration this time, data is transferred between the functions of the base and the application 3 (AI controller) until the comparison result with the data already specified by the read image data is confirmed. Explain.

[0258] The base cuts out the instructed area from one already read image image according to the instruction from the application 3 and gives the bit map data to the application 3. Further, when no image exists at the designated location, the no image code (00H) is stored in the BITMAP size of each designated area.

The application 3 has a function of recognizing each area image data as a character, comparing it with the already registered data, evaluating it, and totaling it.

The process of registering the registration image to be compared is as shown in the flow chart of FIG. First, the target area data is determined by the operation processing and stored in each buffer. As the function here, it is considered that 10 patterns can be registered as image data for comparative evaluation and comparison can be made up to 30 areas per pattern. In addition, the registered pattern to be evaluated for the image to be read is recognized and judged from the information of the commonly designated area from the registered 10 patterns.

After the image information is read from the scanner, the image data is registered by instructing on the basis of the commonly designated area in order to store the identification data of the pattern to be registered this time. Is cut out (YES in S7201, S7202, S72).
03, S7204). Therefore, the number of designated areas is written in the designated number of designated areas of the buffer for indicating the area on the DPRAM, and the designated area coordinates (X1, Y1, X
2, Y2) coordinate data for the number of areas specified (unit: m
m) is written. Then, it sends a cut-out execution command and waits until it receives a cut-out end command.

When the cut-out processing is completed, the base writes the start address on the DPRAM, which is cut out and in which the bit map data of the designated area is written, to the designated area BITMAP pointer, and the data size is set to the BITMAP size. Write (S7205, S72
06, S7207). (This is done because the amount of bit map data is large and the amount of data changes greatly depending on the size of the area.) Data can be packed and written in the memory. However, when the designated area is outside the read image, 00H is written in the data size. When the writing of the data is completed, the base sends a cut end command to the application 3 (S
7208, S7209). The application 3 uses the OCR technology or the like to compare the cut-out bitmap data of each area with a dictionary (database) and converts it into a JIS code, and a common area charactor for each area corresponding to each registered pattern. The head address where the data is stored is stored in the pointer, and the number of character data (the number of characters) is stored in the common area character code size (S721).
0), the data converted into the actual JIS code is stored in the common area character code data (S721).
1). However, if the number of characters exceeds the limit of 200 characters or if the character cannot be recognized, it cannot be recognized (OFF.
H), when outside the specified area image area Outside the area (OFE
H), when there is no character and it is blank, no writing (00
H) is stored. When there is no common area setting (S72
No in 01), these processes are not executed for this common area.

Similar to the common area, the same processing is performed for the unique registration area of each registration pattern, writing is performed in each buffer for each registration area, and the registration data storage processing ends.

FIG. 71 shows a process in which after reading an image to be compared, the data is compared with registered data and evaluated.

If the operation mode is judged to be the automatic mode (YES in S7301), the check operation of the common area is executed (S7302). If it is a registration designation, it starts in that area. In the automatic mode, when the common area is set (YES in S7311 and YES in S7311), the read image data is cut out from the common area (S7).
304, S7305) Character conversion is performed (S730
6), the size of each common charactor code already registered and the data itself are retrieved from each registered pattern,
The coincident one (YES in S7307) is read, and as a result, the code corresponding to registration 1 to registration 10 is written in the discrimination result (S7308), and the discriminated registration number area is stored in the DPRAM instruction area (S7309).
If they do not match (NO in S7307), an undeterminable code is written in the determination result (S7317). If it cannot be determined, this process ends. If there is no common area setting (NO in S7302), only the data of registration 1 is processed (S7316). After recognizing the pattern to be compared, it is cut out from the registration area of the target (S731).
0, S7311) Character conversion is performed (S731
2), as in the processing of the common area at the time of registration, each data is stored in each of the reading area charactor code pointer for reading / reading area charactor code size / reading area charactor code data (S731).
3). After that, the registered data is compared with the read data, and the result is stored as the read area comparison result for each area (S7314).

Next, the process of comparing the registered data with the read data will be described. If the area to be compared or the image data and the read data are not set, a warning is displayed and the comparison operation is not executed. Use the pointer to refer to the registered area processing type data that describes the processing method for each area from area 1 to the area that is set in order, and compare the areas set as comparison (02H). , Write the result in the reading area comparison result. By referring to the registered / read charactor code size and the charactor code data, the result of the match / mismatch between the read data and the registered data and the combined result such as unrecognizable / not written (white) are written.

The process of comparing the registered data with the read data will be described in detail with reference to the flow charts of FIGS. 72, 73, and 74.

[Original Area Designation] As an original area designation method, a method of detecting an image density within a certain range and a method of inputting coordinates of a designated area are known. An example of the former is marker editing (for example, JP9002124), and an example of the latter is an editor.

In marker editing, for example, a color felt-tip pen is used to write an area designating mark on an original or a similar document (for example, a copy of an original), and at this time, the area designating mark is detected. It is a mark detection device. The mark detection device utilizes the fact that the image data described by a color felt pen has a density in a stable predetermined range, and detects image data having a density in a corresponding predetermined range as a mark signal, and subsequently, the mark signal. After the mark width is detected, the mark width is expanded by a predetermined amount to finally detect the mark area (mark area surrounded by the mark).

The area designated by the marker is also converted into a range surrounded by a square having two points as diagonals, and then the same processing as that of the editor described later is performed. That is, the IPU 412 of FIG.
At, the mark area is detected, and only the area is transferred to the page memory 703 in FIG. Application base 700 of FIG.
CPU 710 detects the maximum and minimum addresses in the main / sub-scanning direction of each mark area on page memory 703, and determines (main scanning-direction minimum address, sub-scanning direction minimum address) and (main-scanning direction maximum address, sub-scanning direction minimum address). The maximum address in the scanning direction) is converted into a range surrounded by a square having two diagonal points, and various processes are performed.

[Explanation of the editor] FIG. 54 shows the editor 20.
2 shows an outline. The manuscript to be edited is set based on the manuscript reference position mark 902 in the figure (reference to the upper left of the manuscript), and two coordinates are designated by the stylus pen 900.
The area surrounded by a rectangle with the diagonal points is the area to be edited. Next, edit the contents of the area in the mode select area 8
Input from the 50 key. The above operation is repeated for the number of regions to be edited.

FIG. 55 shows the range of area designation. The origin (0.0) is assumed with reference to the document reference position mark on the right frame of the case as shown in FIG. 55, and the output count numbers in the X and Y directions are in the following ranges. 0-864 (0
Data below is corrected to 0, and data above 864 is
864) and 0-600 in the X-axis direction (data less than 0 is corrected to 0, data exceeding 600 is corrected to 600). The unit of the address of the specified point is [m
m]. That is, the main scanning direction of the original is the X axis, the sub scanning direction is the Y axis, and the X axis can be specified in the range of 0 to 864. However, when coordinates outside the range are specified, the maximum or minimum value of the range is specified. It is corrected to the value. When a plurality of areas are designated and the areas overlap, the area designation data is invalidated.

As shown in FIG. 56, there is a resistor 903 in the editor board in the X and Y directions, and when a part of the coordinate plate 904 is pushed by the stylus pen 900, the resistance pressure is detected and the detected data is obtained. It is sent to the copier as the coordinate position.
The mode selection area 850 also has the same detection method.

FIG. 57 shows an example of keys in the mode select area 850. On the mode select area 850, a document recognition key 851 for designating a document type recognition region, an ID key 852 for designating an ID (attendance number, name, etc.) region on the document, a comparison key 853 for designating a comparison region, A ratio key 854 for designating weighting of the comparison area, a comment key 855 for designating a comment output area, a result print key 856 for designating an area for outputting a comparison calculation result, a numeric keypad 857 for inputting various numerical values from 0 to 9, A setting key 860 for entering the area designation setting mode of the scoring mode,
End key 8 to send the set data to the copier
61, a clear key 862, an enter key 863, and other keys 864 for performing editing (eg, trimming / masking).

Next, the area designation method in the scoring mode will be described. In the present invention, there are 10 types of manuscripts that can be designated, and up to 30 regions can be designated in one manuscript, and the ratio is from 1 to 100. FIG. 58 shows a flow chart when the area designation setting mode of the scoring mode is entered and interrupted.

To enter the setting mode, the setting key is pressed when no other editing mode is set (NO in S6001). Press the setting key (N in S6002
O), the setting lamp for informing that the setting mode is entered is turned on (NO in S6003, S6004, 600).
5). When the setting lamp is pressed again when it is turned on (YES in S6002), the setting lamp is turned off, the data is cleared, and the setting mode is interrupted (S6006, 6007, 6008).
To end the setting mode normally, press the end key described later.

FIG. 59 shows a flow chart of the coordinate input method. In the setting mode (YES in S6101), the area coordinates 1 and 2 are input with the stylus pen 900 (S6).

109, NO), document recognition key, ID key, comparison key,
Area processing type key inputs of the comment key and the result print key are ignored. If it overlaps with the previously input area (YES in S6108), the area registrations 1 and 2 are cleared to the memory and the buzzer becomes twice (S6117 and S611).
8).

Next, the area processing type key input will be described. When the area processing type key is input after the area coordinates are input, the area indicated by the coordinates is stored in the memory as an area for performing the input area processing. At the time of key input, clear key input is also effective. When the clear key is pressed, the data immediately before the press of the clear key is cleared and the input waits again. The user can arbitrarily specify an area number in each area from 1 to 30 using the ten keys. However, if the specified number is specified twice, the subsequent specified number is invalid and is ignored. Also, the ratio key input is valid only after the comparison key input, and the numerical value input range after the ratio key input is 1 to
100. Further, when the areas of a plurality of originals are consecutively set, the area for recognizing the types of originals is made common and only one original can be set. The above area setting is completed by pressing the enter key. When the enter key is pressed, it is determined that the setting of one area has been completed, and the editor enters a state of waiting for area coordinate input of the next area or waiting for completion of area setting of one document.

This area process type key input will be described in detail with reference to the flow charts of FIGS. 60 to 63.

If NO in S6220, it is confirmed that the ID key, the comparison key, the comment key or the result print key is turned on. Yes (S6221). If it is turned on (YES in S6221), the key entered in (mode) of area processing type 1 is stored (S622).
2) Sound the buzzer (S6223). If it is not turned on (NO in S6221), the process ends. If the document recognition key is turned on (YES in S6220), it is confirmed whether document recognition is stored in the area processing type 1 (mode) of the area designation code input of another document (S622).
4) If it is stored (YES in S6224), the process is terminated, and if not stored (NO in S6224), document recognition is stored in (mode) of area processing type 1 (S6).
225) Sound the buzzer (S6226).

If NO in S6204, the numeric keypad input is confirmed (S6213), and if YES in S6213, the area processing type 1 (No.) is stored in the memory (S6213).
6214) Sound the buzzer (S6215). If there is no numeric keypad input (NO in S6213) and enter key input (YES in S6216), area processing type 1 (N
o. ) Is stored as 0FFH (S6217), and one block of the scoring mode area designation data is terminated (S621).
8) The buzzer sounds (S6219).

If NO in S6216, the input of the ratio key is confirmed (S6232). If there is an input (S623
2 YES), 0FFH for area processing type 1 (No.)
Is stored (S6233) and the buzzer sounds (S623).
4), the ratio is stored in the area processing type 2 (mode) (S6235). If no ratio key is input (S623)
(NO in 2), it is confirmed whether the ratio is stored in the area processing type 2 (mode) (S6236). N in S6236
If it is O, the process is ended, and if YES in S6236, it is confirmed that the clear key is turned on (S6237). If it is turned on (YES in S6237), the ratio is cleared to (mode) of area processing type 2 (S6238) and the buzzer sounds (S6239). If NO in S6237,
Confirm the numeric keypad input (S6240), and press Y in S6240.
If it is ES, area processing type 2 (No.) is stored in the memory (S6241) and the buzzer sounds (S6242).
If there is no numeric keypad input (NO in S6240), it is determined whether area processing type 2 (No.) ≠ 0 is stored (S624).
3). If YES in step S6243 and the clear key has been turned on (YES in step S6244), area processing type 2 (N
o. ) Is cleared (S6245) and the buzzer sounds (S6)
246).

If NO in S6243, numeric keypad input is confirmed (S6227), and if YES in S6227, area processing type 1 (No.) is stored in the memory (S6227).
6228) Sound the buzzer (S6229). If there is no numeric keypad input (NO in S6227) and enter key input (YES in S6230), area processing type 1 (N
o. ) Is stored as 01H (S6231), and one block of the scoring mode area designation data is terminated (S621).
8) The buzzer sounds (S6219).

If NO in S6244, the enter key input is confirmed (S6247), and if YES in S6247, one block of the scoring mode area designation data is terminated (S6218), and the buzzer sounds (S6219).

If YES in S6210, the input of the ratio key is confirmed (S6212), and (YE in S6212).
S), the buzzer is sounded (S6234), and the ratio is stored in the area processing type 2 (mode) (S6235). S6
If NO in 212, the process proceeds to S6216.

The data format of one area set by the above operation is shown in FIG. In FIG. 65, if there is no numeric input for area processing type 1 (No.), OF
FH is stored. Area processing type 2 (mode)
Since (No.) and (No.) are valid only when the ratio is input, the blank H is stored when the ratio is not input. If there is no numeric input for area processing type 2 (No.), 1H is stored. The above data is generated for each area setting, and is shown in FIG.
As shown in the flow chart of FIG. 4, when the end key is pressed (YES in S6601), the scoring mode area designation data (consisting of a plurality of blocks) of one original is transmitted to the main CPU (b) in FIG. 5 (S6602). , Turn off the setting lamp and turn on the buzzer (S6603, S660
4). The editor clears the memory while leaving the data in which the document recognition is stored in the area processing type 1 (mode), and waits for the area designation setting mode input of the scoring mode of the next document. Further, the operation unit shown in FIG. 21 is used to change the data already transmitted to the CPU (b) shown in FIG.

Further, the CPU (b) of FIG. 5 stores the data transmitted from the editor in the RAM and transmits the data to the base CPU via the interface. The base CPU stores the transmitted data in the RAM and uses it as basic data for character recognition and comparison.
