In the A7B direction, the pickup hand 97 is stored in the A direction while copying, and the pickup hand 97 is stored in the B direction when turning the page.
After picking up the page, the pick-up hand 97 is moved in the C-D direction to turn the page, and after turning the page, it returns to the D direction and repeats this process.

Furthermore, on the pickup hand 97 there is a fixed rubber roller 98, a pickup rubber roller 101 rotated in both directions by a pickup roller motor 100, and a pickup roller 99 for moving the pickup roller motor 100 and the pickup rubber roller 101 in the C direction. Pickup roller slide SQL.

There are plate members 99a to 99e. This operating state is the 11th
Since the operation is shown in the figure, a detailed explanation of the operation will be given below.

The figure indicated by the dotted line in the figure is the pickup roller motor 1001.
This is a diagram showing the initial state of the pick-up rubber roller 101, which is pulled by a spring 99f hooked to a pin of the PI3 fixed to the pick-up hand 97. Next, when the pickup roller slide 5OL99 is turned on, the plate member 99a connected by the pin P8 is moved to the pickup slide 5.
The plate member 99b, which is pulled toward the OL99 side and is connected by the pin of P9, becomes vertical by the pin of PIO fixed to the pickup hand 97 located at the center, and the plate member is connected by the pin of pH. 99

is a roller sensor for detecting the surface of the Book, S5
Reference numeral 9 denotes a winding sensor that determines whether or not the page is wound up by the pickup rubber roller 101.

FIGS. 13(a) to 13(d) are diagrams showing page turning states. First, FIG. 13(a) shows the first document table 44 and the second document table while sliding the pickup section toward the Book side.
The document table 42 is raised and the aforementioned pickup hand 9
B on both sides by the roller sensor 358 installed at 7.
ook surface is detected and the first document table 4 is placed at an appropriate height.
4 and the second document table 42 are stopped. Next, Figure 13(b)
As shown in the figure, the rubber roller 101 for pickup is slid toward the rubber roller 98 as a fulcrum for the rubber roller 98.

This causes the surface of the Book to bend. Then the 13th
As shown in Figure (C), the pickup rubber roller lot is rotated in the winding direction, and the first document table 44 and second document table 42 are further lowered a little. When the above-mentioned take-up sensor turns on due to these things, the document slides toward the second document table 42 as shown in FIG. 13(d), and after passing the center, the document is picked up at the same speed as the slide direction. Rotate the rubber roller 101 in the opposite direction. These operations cause the pages to be turned over one by one.

Further, FIGS. 14(a) to 14(C) illustrate control when the heights are different on the right and left sides. First, as shown in FIG. 14(a), when the page is close to the cover, the second document table 42 is raised to match the height of the first document table 44, and as shown in FIG. 14(b), Number of pages is Book
If it is in the middle, make the height of the first document table 44 and the second document table 42 the same, and if the number of pages is close to the back cover as shown in FIG. 14(C), set the first document table 44 to the same height. Raise it to match the height of the second document table 42 side. As described above, these controls are performed based on information from the Book thickness sensor. FIG. 15 is a sectional view of section A-D-F.

As shown in the figure, the paper feed roller 40 provided on the A-D-F l-lay section 39 side is stored in the main body side as shown by the dashed line when not in use, and when in use. A-D-F) The setting is completed when the lay portion 39 is pulled from the main body side and the paper feed roller 40 contacts the separation roller 41. This state is shown by a solid line in the figure.

Also, the drive transmission means on the back side, which is not shown in this figure, is the following 16th drive transmission means.
As shown in the figure. In the figure, the figures indicated by dashed and dotted lines show the state separated from the drive means, and the figures indicated by solid lines show the state coupled with the drive transmission means. First, the paper feed roller 40
A gear 40a is fixed to the shaft of the separation roller 41, and a gear 41a is fixed to the shaft of the separation roller 41 (the shaft is received on the main body side) with a spring (not shown) interposed therebetween. Also, the sprocket 41c fixed to the same shaft as the gear 41b that meshes with the gear 41a receives driving force from the chain 41d (supplied from the main motor side) that fits the sprocket 41c.

Next, these operations will be explained. First, the sprockets 41c and 41b receive driving force from the sprocket on the main motor side (not shown) via the chain 41d, and this starts the rotation of the gear 41a.The driving force is also transmitted to the gear 40a, and the paper feed roller 40 starts to rotate. starts feeding paper. However, at this time, the rotation of the gear 41a is absorbed by the spring for an initial predetermined time because the separation roller 41 has a spring between its shafts. Start rotating in the opposite direction to 40. Through these operations, the documents are fed one by one toward the second document table 42 without being fed multiple times.

FIGS. 17(a) and 17(b) show a side view and a rear view of the shutter mechanism for stopping the original in A-D-F mode. Although the table side will be described, the first document table side has a similar configuration. Furthermore, both figures show a state in which the shutter is raised (a state in which the document is stopped). First, place the 10
There are 2 shutters 5QL2 and 1 through the pin of PI3.
There is a plate member 02a, and a P2O pin fixed to this plate member 62a is inserted into a long hole in the plate member 102b. Further, in the center of this plate member 102b, there is a pin P21 fixed to the second document table main body 85, and furthermore, there is a notch on the side opposite to the elongated hole, and the shaft 102c is inserted through this notch. is fixed to the plate member 102d. Therefore, when the shutter 5OL2/102 is turned on, the plate member 102a is pulled toward the shutter 5OL2/102, and similarly, the long hole side of the plate member 102b is also pulled toward the shutter 5OL2/102.
It is pulled to the L2/102 side. For this reason, the notch side of the plate member 102b is pushed out to the opposite side, so the plate member 102b
d will also slide toward the back. Due to these, P2 fixed to the shutter member 103
Pins 5 to P28 are pushed upward by oblique long holes in the plate member 102d. Also, Fig. 17 (
As shown in b), P fixed to the second document table main body 85
The plate member 102d slides without shaking by the pins 22 to P24, and the spring 102e attached to the second document table main body on one side and the plate member 102 on the other side causes the plate member 102d to slide when the shutter 5QL2 and 102 are turned off. 102d, thereby pulling down the shutter member 103.

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

Next, FIG. 18(b) shows mode 2 in the A-D-F mode, which is a mode mainly used for sheet originals of 1/2 or less of a long length. There are two sheet originals on the second original table 42, the shutter member 105 and the shutter member 1.
03, both are stopped to the right. Next, the first
FIG. 8(C) shows mode 3 in the A-D-F mode, which is also a mode used for sheet originals of 1/2 or less of a long length, in which the first original table 44. Two sheet originals are placed on the second original table 42 and stopped at the center by a shutter member 103. Next, FIG. 18(d) shows mode 4 in the A-D-F mode, which is also a mode used for sheet originals of 1/2 or less of a long length. One document is stopped at the center by a shack member 103. Above, Figures 18(a) to 18(
d), each of these modes can be defined as T below.
ABLE-1, and an example of its use will also be explained.

As shown above, Modes 2 and 3 are particularly effective when changing the magnification, and conventionally when A-D-F was used, it was not possible to copy from two sheets to one sheet as shown in the present invention. However, in the present invention, this is possible because the A-D-F belts are divided so that they can be driven independently.

From now on, the present invention will be further explained in detail with reference to flowcharts.

First, Figures 20(a) to 20(b) show the master CPU2.
00 main flowchart is shown. First, when the power is turned on, the operation starts from step la. First step 1a
In step 2a, the RAM and Port are initialized, and in step 2a, the operation panel is controlled.Furthermore, two types of counters that can be set in order to more effectively utilize the page turning control, which is a feature of the present invention, are also set in this step. These two types of counters, the page pass counter and the page counter, can be operated in the same way as setting the number of copies (this page bus
The counter is used to set the number of blank pages (therefore, one copy cycle is not performed), and the page counter is a counter for page turning including copy cycles. Controls the display that checks various key groups and displays the status. In step 3a, the fixing device is controlled, and at this time, the fixing device is controlled by keeping W a i at an appropriate temperature. Step 4a
is a control for the slave ICPU 201, and sends the status of the master CPU 200 and slave 2CPU 202, and receives the status of the slave ICPU 201. Step 5a is slave 2 CPU 202
control, and sends the status of the master CPU 200 and slave 1cPU 201, and sends the status of the slave 2cPU
It receives the status of 202. Step 6a
is a flag that is generated when copying is possible and the copy key is pressed in step 2a. In this step, this flag is determined. If it is not set, the process returns to step 2a, and if it is, the following copy is executed. Enter cycle mode. Step 7a is the same as step 4a, and step 8a is the same as step 5a, so a description of both will be omitted. Step 9a is for counting drum clocks and scan clocks necessary for sequence control, and step 10a is for controlling the fixing device within a temperature range that allows fixing. Then step ll mill step 32a and 20th
Steps 20 to 3b in FIG. 3(b) are for performing ON-OFF control of each load as shown in the diagram, so their explanation will be omitted. Next, in step 4b, the condition of the machine during the copy cycle is checked, and in step 5b, a check is performed if the condition is serious, such as a fuser running out of control, which may have a danger of affecting the human body. If not, proceed to step 10b, and if it is a serious abnormality, proceed to the next step. In step 6b, the full load is reset, and in step 7b, this state is sent to the slave CPU 201,
In step 8b, this state is also transferred to the slave 2CPU2.
02, and in step 9b, it is brought into the T-T ALT state and all functions are stopped. Also, in step tab, it is determined whether or not there is a minor abnormality (minor abnormality indicates an abnormality such as paper emptying). If the abnormality is minor, proceed to the next step, and if not, proceed to step 16b. Step 12b is the timing to obtain the end of the current copy cycle, and if it is the t12 timing, the process returns to step 2a in FIG. 20(a), and if it is outside the t12 timing, no new load control is performed in step 13b. In step 14b, the appropriate load ON control is disabled, and in step 14b, this state is sent to the slave CPU 201.
5b similarly sends this state to the slave 2 CPU 202. In step 16b, the number of copies is counted and checked, and in step 17b, it is determined whether or not the copy cycle has ended, and if not, the second
Return to step 7a in FIG. 0(a), and if completed, proceed to the next step. Step 18b determines whether the completed copy cycle was in Book mode, and
If it is not the mode, the process proceeds to step 22b, and if it is the Book mode, the process proceeds to the next step. In step 19b Boo
It is determined whether or not the page in k mode is the final page set. If the page is the final page, the process returns to step 2a in FIG. 20(a), and if it is not the final page, the process proceeds to the next step. In step 20b, a page-turning command is sent to the slave CPU 201, and in step 21b, it is determined whether or not page-turning has been completed. If the setting is not completed, the process returns to step 20b, and if the setting is completed, the process shown in FIG. The process returns to step 7a of a), and a new copy cycle begins. Also, step 22
In b, it is determined whether the A-D-F mode is selected, and the A-D
If the mode is not -F, the process returns to step 2a in FIG. 20(a), and if the mode is A-D.F, the process proceeds to the next step. In step 23b, it is determined whether or not all originals have been sent out in the A-D-F mode, and if the original is the end, the second
Return to step 2a in Figure 0 (a), and if the document is not at the end, proceed to the next step. In step 24b, the above-mentioned A
-Slave so that sheet originals are set in the specified mode in various modes in D-F mode], C
The slave 25b determines whether or not a sheet original has been set in this mode, and if the setting is not completed, the process returns to step 24b, and if the setting is complete, the process proceeds to step 7a in FIG. 20(a). It returns and enters a new copy cycle.

Figure 21(c) to Figure 21(g) are slave lCPU2
This shows the main routine of step 01, and the process starts from step lc when the power is turned on. First, in step lc, the RAM and port are initialized, and the process proceeds to the next step. During this time, however, the lN-0UT SW of the document table is checked as shown in step 19c, and the relevant S
If W is OFF, steps 20 to llc will be skipped and the process will jump to step 12c, resulting in a wait state, which I forgot to write.

In step 2C, it is determined whether the document table HP sensor 1 is ON or not. If it is ON, the process proceeds to step 5c, and if not, the process proceeds to the next step. In step 3c, the lift/lower motor l is turned on in the downward direction, and in step 4c, the motor l is turned on in the downward direction.
Set 0PY WAITI and proceed to step 7c.

In addition, in step 5c, the ascending/descending motor l is set to 0FFi:
Then, step 6C resets copyWAITI. In step 7C, it is determined whether or not the document table HP sensor 2 is ON. If it is ON, the process proceeds to step 10c, and if not, the process proceeds to the next step. In step 8C, the lift/lower motor 2 is turned on in the downward direction, and in step 9

This concludes the explanation of the main flowchart of the slaver CPU 201.

Next, the main flowcharts of the slave 2 CPU 202 are shown in FIGS. 22(a) and 22(b) and will be explained. First, when the power is turned on, the process starts from step 1h. First, in step 1h, RAM and Po
rt is initialized, and in step 2h, the status is checked to see if there is any transfer paper in the paper path of the sorter system or if there is no paper in the intermediate tray.In step 3h, it is determined whether it is a copy cycle or not, and the copy cycle is started. Otherwise, the process returns to step 2h, and if it is a copy cycle, the process proceeds to the next step. In step 4h, a drum clock count is performed, and in step 5h, it is determined whether or not double-sided copying is to be performed.

In steps 1.1h to 14h, route switching SQ is performed to change the transport bus in order to guide the transfer paper to the intermediate tray.
This is to perform ON-OFF control of L. Also, from step 15h to step 21h, the reversing SoL and reversing roller for reversing the transfer paper for double-sided copying are turned on and off.
This is F control. The 22nd
Proceed to step li in Figure (i).

Next, the processing system when it is determined in step 10h that the image is not for both sides will be explained from step 22h onwards.

First, I will explain the sorter mode. Sorter mode
is a mode in which the transfer paper is discharged to the paper discharge tray 13a shown in FIG.
This is a mode in which paper is ejected by number of copies using the following methods, and sorter mode 3 (not shown in the flow, but if it is determined that it is not mode 1 or mode 2, it is mode 3) is the mode in which paper is ejected in the same way. This is a mode in which paper is ejected page by page using tray 13b and subsequent trays.

First, in step 22h, paper ejection SO■,1 is turned on so that the transfer paper is ejected to the paper ejection tray 13b or later, and in step 24h, it is determined whether or not the mode is sorter mode 2. If not, proceed to step 32h,
If it is sorter mode 2, proceed to the next step.

The information is stored in the internal RAM, and it is determined whether or not the information sent in step 3j includes information on a serious abnormality. If there is no serious abnormality, proceed to step 6j, and if there is a serious abnormality, proceed to the next step. Proceed to step. In step 4j, all loads are turned off, and in step 5j, the system is brought into a HALT state and all functions are stopped. In step 6j, it is determined whether or not the above-mentioned information includes information on a minor abnormality, and if there is no minor abnormality, the process advances to step 8j and Ret is the end of the interrupt processing routine.
The urn instruction is executed, and if there is a minor abnormality, in step 7j, information for processing the appropriate load is stored in the internal RAM in order to prevent subsequent processing cycles, and in step 8j, the interrupt processing is executed. The routine ends by executing a Return instruction. Next, the interrupt processing of the slave 2 CPU 202 will be explained with reference to the flow shown in FIG. 24(k). First, this interrupt processing is generated by one of the control signals from the master CPU 200, and in step 1k, the status of the slave 2 CPU 202 is sent to the master CPU 200 side, and in step 2k, the state of the slave 2 CPU 202 is sent to the master CPU 200 side, and in step 2k, the state of the slave 2 CPU 202 is sent to the master CPU 200 side. The I/roll 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 it is not a serious abnormality, the process proceeds to step 6k; Then proceed to the next step. Step 4 turns off all loads, and step 5k
At this point, the system is set to IAI, T state and all functions are stopped.

Also, in step 6k, it is determined whether or not the above-mentioned information includes information on a minor abnormality, and if it is not a minor abnormality, the process proceeds to step 8, and a Return instruction is executed, which is the end of the interrupt processing routine. , if it is a minor abnormality, step 7
k, information for processing the appropriate load is stored in the internal RAM in order to avoid performing subsequent processing cycles.
In step 8k, a Return instruction is executed to end the interrupt processing routine.
