FIGS. 13 (a) to 13 (d) are diagrams showing a page turning state. First, Fig. 13 (a) shows the pickup section as a Book.
The first platen 44 and the second platen 42 are raised while sliding to the sides, and the surface of the book on both sides is detected by the roller sensor S58 installed in the pick-up hand 97 described above.
The first platen 44 and the second platen 42 are stopped at an appropriate height. Next, as shown in FIG. 13 (b), the pickup rubber roller 101 is slid toward the rubber roller 98 as a fulcrum of the rubber roller 98. This causes the Book surface to flex. Next, as shown in FIG. 13 (c), the pick-up rubber roller 101 is rotated in the winding direction, and the first platen 44 and the second platen 42 are slightly lowered. As a result, when the take-up sensor is turned on, as shown in FIG. 13 (d), it is slid in the direction of the second platen 42, and after passing the center, it is picked up at the same speed as the slide direction. The rubber roller 101 is rotated in the opposite direction. By these operations, pages are turned one by one.

FIGS. 17 (a) and 17 (b) show a side view and a rear view of a shutter mechanism diagram for stopping a document in the A, D, and F modes, for example, a second document. Although the table side has been described, the first document table side has the same configuration. Both figures show a state in which the shutter is raised (a state in which the document is stopped). First, there is a shutter SOL2 102 at the back side of the second platen main body 85, a plate member 102a via a pin P19, and a pin P20 fixed to the plate member 62a having a pin 10
It is put in the long hole in the plate member of 2b. Also this plate member
The center of 102b is fixed to the second platen body 85
There is a pin P21, and further, a notch is provided on the side facing the long hole, and the shaft of 102c passing through the notch is fixed to the plate member of 102d. Therefore, when the shutters SOL2 / 102 are turned on, the plate member 102a is pulled toward the shutter SOL2 / 102, and similarly, the elongated hole side of the plate member 102b is also pulled toward the shutter SOL2 / 102. Therefore, the notch side of the plate member 102b is pushed out to the opposite side, so that the plate member 102d also slides toward the back side. As a result, the pins P25 to P28 fixed to the shutter member 103 are pushed upward by oblique long holes in the plate member 102d. Also,
As shown in FIG. 17 (b), the plate member 102d slides without blur by the pins P22 to P24 fixed to the second platen main body 85, and the plate member 102d slides one side to the second platen main body. When the shutter SOL2 / 102 is turned off by the spring 102e attached to 102, the plate member 102d is pulled,
As a result, the shutter member 103 is pulled down.

FIGS. 18 (a) to 18 (d) are diagrams showing the control of various modes which are further classified in the A / D / F mode.
Also, in each figure, there is a considerable gap between the sheet document, the shutter and the belt, but this is to clarify the operation of each and differs from the actual system. First
FIG. 18A shows a mode 1 in the A / D / F mode, which is a mode mainly used for a long sheet document.
The belts of both the document table 44 and the second document table 42 are rotated, and the sheet document is stopped to the right by the shutter member 105 on the first document table 44 side.

Next, FIG. 18 (b) shows a mode 2 in the A / D / F mode, which is a mode mainly used for a sheet having a length of 1/2 or less. The sheet document is stopped on the document table 42 to the right by two shutter members 105 and 103 together. Next, FIG.
・ Mode 3 in DF mode.
This is the mode used for the following sheet document. The sheet document is stopped at the center by the two-sheet shutter member 103 on the first document table 44 and the second document table 42. Then the 18th
FIG. 4D shows a mode 4 in the A, D, and F modes, which is also used for a sheet of a half-length sheet or less, in which one sheet document is placed on the second platen 42. Shutter material
Stopped at the center by 103. The description of FIGS. 18 (a) to 18 (d) has been given above. Each of these modes is shown in Table 1 below, and examples of uses thereof are also described.

As described above, mode 2 and mode 3 are particularly effective at the time of zooming. Conventionally, when using A / D / F, two to one sheets cannot be copied as shown in the present invention. However, in the present invention, this is made possible because the A, D, and F belts are divided so that they can be driven independently.

In step 3d, it is determined whether or not COPY WAITs 1 and 2 are standing. If either or both are standing, the process returns to step 22c in FIG. 21 (c). If both are not standing, the process proceeds to the next step. . At step 4d, the A / D / F mode is set and the process returns to step 18c of FIG. 21 (c). Next, FIG. 21 (c)
The processing when the A / D / F sensor is not ON in the judgment of step 22c is shown in step 5d of FIG. 21 (d). First, in step 5d, a subroutine of steps 2c to 6c in FIG. 21C is processed, and the first platen is set to H.
・ Perform an operation to move to the P sensor, and
In step 6d, similarly, steps 7c to 11c in FIG.

Next, the processing when the book mode is determined in step 20c of FIG. 21 (c) will be described from step 11d.

First, in step 11d, set COPY WAIT4,
In step 12d, a process in which steps 8d to 10d are converted into a subroutine is performed, and in step 13d, the document table IN / OUT
Judge whether the SW is ON or not.
Return to 11d, and if it is ON, proceed to the next step. Step 14d
Then, using the document size sensor, determine the presence or absence of Book,
If there is no Book, the process returns to step 11d. If there is a Book, the process proceeds to the next step. At step 15d, the size in the direction perpendicular to the moving direction of the scanner is read from the original size sensor at the previous step. In step 16d, the copy start flag from the master CPU 200 is determined. If the copy is not started, the process returns to step 11d, and if the copy is started, the process proceeds to the next step. In step 17d, the up / down motors 1 and 2 are turned on, and in step 18d it is determined whether or not the page turning mode is set. If not, the process proceeds to step 1e in FIG. If so, proceed to the next step. In step 19d, the pickup section is moved to the initial position for turning the page, and the
At 20d, it is determined whether or not the roller sensor in the pickup section is turned on. If it is not turned on, the process returns to step 19d, and if it is turned on, the process proceeds to the next step. At step 21d, the up / down motors 1 and 2 are turned off.At step 22d, the pickup section is fully slid to read the Book size in the same direction as the movement of the scanner.At step 23d, the pickup roller slide SOL is turned on, and at step 24d. To turn on the pick-up roller motor in the take-up direction.
Then, ON / OFF of the take-up sensor in the pickup section is determined, and this sensing is repeated until the take-up sensor is turned on. When it is turned on, the process proceeds to the next step. In step 25d-a, it is determined whether or not the above-mentioned page pass counter has been set. If not, the process proceeds to step 26d. If the page pass counter has been set, the value of the page pass counter is subtracted. Proceed to step. Step 25d-b sets the operating pickup slide SOL and the pickup roller motor to O.
Set to FF and return to step 23d. Therefore, the page is skipped in steps 23d to 25d-b. At step 26d, the pickup portion is slid, and at step 27d, it is determined whether or not the pickup portion is at or above the center (whether it has slid half or more). If it is below the center, this sense is repeated. Proceed to step. At step 28d, the pick-up roller motor is turned on in the half-turn direction, the pick-up slide SOL is turned off, at step 29d, the up / down motor 1 is turned on in the up direction, and at step 30d, it is determined whether or not the pick-up section has fully slid. Then, this sense is repeated until a full slide is performed, and when the full slide is performed, the process proceeds to the next step. At step 31d, the pickup portion is housed. At step 31d, the ascending / descending motor 2 is turned on in the ascending direction, and the process proceeds to step 1e in FIG. 21 (e). In step 1e, the UP / HP sensor 1 on the first platen side
Judge whether or not is turned on, and if it is not turned on, step 3e
Go to the next step if it is ON. In step 2e, the up / down motor 1 is turned off, and in step 3e, the second
It is determined whether or not the UP / HP sensor 2 on the platen side is ON. If it is not ON, the process proceeds to step 5e. If it is ON, the process proceeds to the next step. In Step 4e, the ascent / descent motor 2
Is turned off, and in step 5e, it is determined whether or not both of the UP / HP sensors 1 and 2 are ON. If not ON, the process returns to step 1e, and if ON, the process proceeds to the next step. At step 6e, it is determined whether or not the line is the right reference or not (determination of right page copy or left page copy). If not right, the process proceeds to step 8e, and if right, the process proceeds to the next step. In step 7e, the right reference data is stored at various timings t13, t14, and t15 for scanner control, and the flow advances to step 9e. In step 8e, t13, t14, t15
To store the left reference data. Copy Cy in Step 9e
cle (corresponding to step 6a in FIG. 20 (a)) is set, and in step 10e, counting of the drum and the scan clock is started. Steps 11e to 21e are a flow for performing sequence control of the scanner system, and will not be described here. Next, in step 22e, it is determined whether or not the copy cycle is at the end. If the copy cycle is at the end, the process proceeds to the next step, and if not, the process returns to step 11e. In step 23e, it is determined whether or not the page turning mode is set.
Proceed to 25e and proceed to the next step if it is not a page turning mode. At step 24e, it is determined whether or not it is a continuous page copy,
If it is not continuous page copying, the process returns to step 2c in FIG. 21 (c). In the case of continuous page copying, the process proceeds to step 26e. Step 25e determines whether or not continuous page copying is possible (determines whether it is necessary to turn pages) or not. If continuous page copying is not possible, the process proceeds to step 27e. If continuous page copying is possible, the process proceeds to the next step. move on. In step 26e, since it is continuous shooting, t1
The reference page at the timing of 3, t14, t15 is set on the opposite side, and the process returns to step 6e. At step 27e, it is determined whether or not the page is the End page in the Book mode. If the page is the end page, the process returns to step 2c in FIG. 21C, and if not, the process proceeds to the next step. To elaborate further,
The determination of the end page is based on the contents of the page counter described above, and is performed until the content of the page counter becomes 0 (a set value in the case of the addition display type).
After the subtraction, it is determined whether the value is 0 or not. However, this is not the case when the sensor for detecting the presence / absence of a document determines that there is no document, and the content of the page counter is rewritten to 0 by giving priority to the information of the absence of the document. In step 28e, the ascent / descent motors 1 and 2 are turned on in the descending direction. In step 29e, an appropriate position for lowering the first and second original tables to below the position where the page can be turned by the pickup unit is checked. This sensing is repeated until the proper position is reached, and when the proper position is reached, the process proceeds to the next step. In step 30e, the ascent / descent motors 1 and 2 are turned on in the ascending direction, and the process returns to step 19d in FIG. 21 (d) to repeat the above-described Book mode processing. Next, when it is determined in step 21c of FIG. 21 (c) that the mode is the A / D / F mode, the mode processing is started from step 1f of FIG. 21 (f). COPY WAIT in Step 1f
5 is set, and in step 2f, it is determined whether or not the sheet original is set by the A / D / F sheet feeding sensor. If the sheet is not set (when the sensor is OFF), the process returns to step 1f, and the setting is performed. If so, proceed to the next step. Step 3f
Then, the copy start flag from the master CPU 200 is determined, and if it is not a copy start, the process returns to step 1f.
If it is a copy start, proceed to the next step. Step 4f
Then, the A, D, and F paper feed rollers are turned on, and in step 5f, it is determined whether or not the mode 1 shown in Table 1 is described. If not, the process proceeds to step 4f and proceeds to step 4f. If so, proceed to the next step. In step 6f, it is determined whether or not the sheet sensor 4 is ON. If the sheet sensor 4 is not ON, this sensing is repeated, and if ON, the process proceeds to the next step. At step 7f, the belt motor 2 is turned on. At step 8f, the A / D / F paper feed roller is turned off after a predetermined time. At step 9f, it is determined whether or not the sheet sensor 1 is on. Returning to step 9f, if this sensing is repeatedly turned on, the process proceeds to the next step. In step 10f, the belt motor 1
Is turned on, and it is not described in step 11f, but also includes a determination as to whether or not the sheet document is not more than 1/2 of the maximum copyable size. If so, it is determined whether or not the sheet sensor 3 has been turned off. If it has not been turned off, this sensing is repeated, and if it has been turned off, the process proceeds to the next step. In step 12f, the belt motor 2
Is turned off after a predetermined time, and in step 13f, the sheet sensor 1 is turned off.
It is determined whether or not is turned on. If it is not turned on, this sensing is repeated, and if it is turned on, the process proceeds to the next step. At step 14f, the shutter SOL1 is turned on, and at step 15f, the belt motors 1, 2 are turned off after a predetermined time. Step 16f
Then, store the right reference data at t13, t14, t15 described above,
At step 17f, shutters SOL1 and SOL2 are turned off, and step 18
In step f, the COPY Cycle (corresponding to step 6a in FIG. 20 (a)) is set. In step 19f, the drum and scan clocks are counted. In step 20f, steps 11e to 22e in FIG. 21 (c) are performed. The subroutine is processed, and in step 21f, it is determined whether or not the A / D / F sheet feed sensor is ON. If not, the process returns to step 18c in FIG. If so, proceed to the next step. In step 22f, turn on belt motors 1 and 2.
Then, in step 23f, the belt motors 1 and 2 are turned off after a predetermined time.

Proceed to step 16g. If not mode 4 (mode 2 or mode 3), the process proceeds to the next step. Next, patterns 1 to 6 described in the following steps will be described with reference to Table-2.

First, this pattern represents a combination of ON / OFF of the sheet sensors 1 to 4, and the appropriate load is turned ON for the pattern 1 and the patterns 3 to 6.
・ OFF is performed, and in pattern 2 mode 2 to mode 4 which is smaller than 1/2 of the maximum copy size among the modes shown in Table-1, the mode can be determined because the sheet original can be determined to be larger in this pattern. The mode is switched to the mode 1 which can be up to the maximum copy size. First step 25
In f, it is determined whether or not the pattern is pattern 1. If it is not pattern 1, the process returns to step 24f. If it is pattern 1, the process proceeds to the next step. In step 26f, the belt motor 2
Is turned on, and in step 27f, the A / D / F paper feed roller is turned off after a predetermined time. In step 28f, it is determined whether or not pattern 2 has occurred. If pattern 2 has not occurred, the process proceeds to step 30f, and if pattern 2 has occurred, the process proceeds to the next step. In step 29f, A, D, F
The mode is switched from the mode (mode 2 or mode 3) to mode 1 and the process returns to step 9f. In step 30f, it is determined whether pattern 3 has occurred. If pattern 3 has not occurred, the process returns to step 28f, and if pattern 3 has occurred, the process proceeds to the next step. In step 31f, the belt motor 1 is turned on, and in step 32f, the A, D, and F paper feed rollers are turned on. Further, the process proceeds to FIG. 21 (e), and in step 1g, it is determined whether or not a pattern has occurred. If pattern 4 has not occurred, the process proceeds to step 3g. If pattern 4 has occurred, the process proceeds to the next step. move on. In step 2g, the A / D / F paper feed roller is turned off after a predetermined time.

If the pattern 6 has occurred, the process proceeds to the next step. In step 6g, the shutter SOL1 is turned on, and in step 7g, the belt motors 1, 2 are turned off after a predetermined time. In step 8g, it is determined whether the A, D and F modes described above are the mode 2, and the mode 2 is determined. If not, go to step 10g and go to mode 2
If so, proceed to the next step. At step 9g, the full scan data is stored at t13, t14, and t15 necessary for controlling the above-described exposure optical system, and the process returns to step 17f in FIG. 21 (d). At step 10g, the belt motor 1 is turned on in the reverse direction.
Then, in step 11g, it is determined whether or not pattern 3 has occurred. This sensing is repeated until pattern 3 occurs. When pattern 3 occurs, the process proceeds to the next step.
At step 12g, the belt motor 1 is turned off after a predetermined time,
At step 13g, the center reference data (accurately, the position of the center sheet original size becomes the start position of the scanner) is stored at t13, t14, and t15 described above.
The process returns to step 17f in FIG. Next, step 14g and step 15g, which have been described above, are omitted here. Next, the processing when it is determined that the mode is the mode 4 in step 24f of FIG. 21 (d) will be described. First, in step 16g, it is determined whether or not pattern 1 has occurred. This sensing is repeated until pattern 1 occurs.

The half center reference data is stored at t15, and the flow returns to step 17f of FIG. 21 (d). In this mode 4, the belt motor 1 is rotated at an appropriate timing for paper discharge (at the time of return of the exposure optical system), but this portion is not shown in the flowchart because it seems that there is no particular problem. This concludes the description of the main flow chart of slave 1 CPU 201.

Next, the main flow chart of slave 2 CPU 202
This will be described with reference to FIGS. 22A and 22B. First, the processing is started from step 1h when the power is turned on. First, in step 1h, the RAM and Port are initialized.In step 2h, a check is made to see if there is no transfer paper in the sorter paper path or if there is no paper in the intermediate tray.In step 3h, a copy cycle is performed. Is determined, the process returns to step 2h if not a copy cycle, and proceeds to the next step if it is a copy cycle. In step 4h, the clock count of the drum is performed. In step 5h, it is determined whether or not double-sided copying is performed. If not, the process proceeds to step 10h. If it is double-sided copying, the process proceeds to the next step. Step
Steps 6h to 9h are ON / OFF control of the feed roller of the intermediate tray by referring to the drum clock.Step 10h determines whether or not the copy sequence is for double-sided printing. If so, proceed to the next step. In steps 11h to 14h, O of the path switching SOL for changing the transport path to guide the transfer paper to the intermediate tray is performed.
N / OFF control is performed. From step 15h to step 21h, ON / OFF control of the reversing SOL and the reversing roller for reversing the transfer paper for double-sided copying is performed. After passing through these double-sided control systems, the process proceeds to step 1i in FIG. 22 (i).

Next, the processing system when it is determined in step 10h that it is not for both sides will be described from step 22h. First, the sorter mode will be described first. The sorter mode 1 is a mode for discharging the transfer paper to the paper discharge tray 13a shown in FIG. 1 and the like, and the sorter mode 2 is a mode for discharging the paper for each copy using the paper discharge tray 13b and thereafter. Sorter mode 3
(Not shown in the flow, but if it is determined that the mode is not Mode 1 and Mode 2 is Mode 3), the mode is a mode in which the sheet is discharged for each page using the discharge tray 13b and thereafter. First, in step 22h, the paper discharge SOL1 is turned on so that the transfer paper is discharged to the paper discharge tray 13b and thereafter. In step 24h, it is determined whether or not the sorter mode 2 is set. Proceed to 32h and sorter mode 2
If so, proceed to the next step. Step 25h ~ Step 31h

Thereafter, ON / OFF is repeated in order from the top according to the number of copies. A and B shown in the figure indicate the value of the number of copies in A, and the timing data in the case of B. is there.

After passing through these processing systems, the process proceeds to step 1i in FIG. In step 32h, which is the processing of sorter mode 3, ON / OFF is repeated from the top in order from the top in accordance with the number of copies to be discharged from the sheet discharge SOL2 for discharging to the sheet discharge tray 13b and thereafter. The number of cycles indicates the number of copies. After passing through this processing system, the steps shown in FIG.
Go to 1i.

Next, the description of step 1i in FIG. 22 (b) will be continued. First, in step 1i, it is determined whether or not the copy cycle is at the end. If it is not the end, the process returns to step 5h in FIG. 22 (a), and if it is at the end, the process proceeds to the next step. In step 2i, all SOLs shown in FIG.

The control signal is generated from one of the control signals from 00.In step 1j, the state of the slave 1 CPU 201 is sent to the master CPU 200 side.In step 2j, the control information from the master CPU 200 is stored in the internal RAM. It is determined whether or not the information transmitted in step 3j includes information on a serious abnormality. If the information is not serious, the process proceeds to step 6j. If the information is severe, the process proceeds to the next step. In step 4j, all loads are turned off and step 5j
In HALT state, all functions are stopped. In step 6j, it is determined whether or not information on the light abnormality is included in the above-described information. If the light abnormality is not affirmative, the flow proceeds to step 8j to execute the Return instruction, which is the end of the interrupt processing routine, and execute the light abnormality. If so, in step 7j, information for processing an appropriate load is stored in the internal RAM in order to prevent a subsequent processing cycle from being performed, and in step 8j, a Return instruction, which is the end of the interrupt processing routine, is issued. Execute and end. Next, the interrupt processing of the slave 2 CPU 202 will be described with reference to the flow of FIG. First, this interrupt processing is generated from one of the control signals from the master CPU 200. In step 1k, the state of the slave 2 CPU 202 is transmitted to the master CPU 200 side, and in step 2k, the control from the master CPU 200 is performed. The information is stored in the internal RAM, and in step 3k, it is determined whether or not the transmitted information includes information on a serious abnormality. If not, the process proceeds to step 6k. Proceed to step. At step 4k, all loads are turned off, and at step 5k, the HALT state is set and all functions are stopped. Also, in step 6k, it is determined whether or not the information of the light abnormality is included in the information described above.
If it is not a minor abnormality, proceed to step 8k and execute a Return instruction that ends the interrupt processing routine.If it is a minor abnormality, apply an appropriate load in step 7k to prevent the subsequent processing cycle from being performed. The information for processing is stored in the internal RAM, and in step 8k, the Return instruction, which is the end of the interrupt processing routine, is executed, and the processing ends.
