A back pulley 95e, which is also connected by the shaft 95d, a back pulley 95f (not shown), and a part of 95g are attached to the pick-up hand 97 with a hard wire, and the pick-up hand 97 is moved in a direction perpendicular to the scanner (direction A-8). ). In the A-8 direction, the pickup hand 97 is stored in the direction toward copying, and when turning the page, the pickup hand 97 is moved toward B.
After picking up the page, the pick-up hand 97 is moved in the C-D direction, and after the page is turned, 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 100,
This is a diagram showing the initial state of the pickup rubber roller 101, which is pulled by a spring 99f hooked to the pin of the PI3 fixed to the pickup 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

At this time, the plate members 99d and 99e are arranged in vertical holes 99i and 99j, respectively.
The PI3 and the pins of the PI3 fixed to the hand 97 allow it to be pushed up without wobbling.

These states are shown by solid lines.

FIG. 12 shows a layout diagram of the sensors installed in the pickup section. In the figure, 356 is the H of the pickup hand 97.
-Pickup hand HP sensor for detecting the HP of the pickup table 96, S57 is the pickup table HP sensor for detecting the HP of the pickup table 96, S58 is the roller sensor for detecting the surface of the Book, 559
is 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
The surfaces of the Book on both sides are detected by the roller sensor S'58 installed at 7, and the first document table 44 and the second document table 42 are stopped at appropriate heights. Next, Figure 13 (b
), the pickup rubber roller 101 is slid toward the rubber roller 98 as a fulcrum for the rubber roller 98. This causes the surface of the Book to bend. Next, the first
As shown in Figure 3 (C), the rubber roller 101 for pickup
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 lot 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 rollers 40 provided on the lay part 39 side are stored in the main body side as shown by the dashed line when not in use, and when in use, -D-F) The setting is completed when the lay section 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, paper feed roller 4
Gear 40a fixed to glaze 0 and separation roller 41
A gear 41a is fixed to the shaft (the shaft is supported 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, 1 through the P2O pin.
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. Also, 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 passes through this notch. It is fixed to the plate member 102d. Therefore, when the shutters 5OL2 and 102 are turned on, the plate member 102a is pulled toward the shutter 5QL2-102, and similarly, the elongated hole side of the plate member 102b is also pulled toward the shutter 5OL.
It is pulled to the 2/102 side. Therefore, the notch side of the plate member 102b is pushed out to the opposite side, so the plate member 102d
will also slide towards the back. Due to these things, P25 fixed to the shutter member of 103
The pin P28 is pushed upward by the oblique elongated hole in the plate member 102d. Also, Fig. 17 (b
), P2 is fixed to the second document table main body 85.
The plate member 102d slides without shaking by the pins 2 to P24, and the spring 102e attached to the plate member 10 on one side to the second document table main body allows the shutter 5QL2 and 102 to be turned off. The plate member 102d is pulled, thereby lowering the shutter member 103.

FIGS. 18(a) to 18(d) are diagrams showing control of various modes that are further differentiated 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 platen 42, the shutter member 105 and the center member 1.
03, both are stopped to the right. Next, the first
Figure 8 (C) is mode 3 in A-D-F mode,
Similarly, this mode is used when a sheet document is 1/2 or less of the long length, and the first document 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 long sheet originals of 1/2 or less in size. One document is stopped at the center by a shutter member 103. Although the explanations of FIGS. 18(a) to 18(d) have been made above, each of these modes is shown in Table-1 below, and an example of its application 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, by turning on the power, the operation starts from step 1a. 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 a counter for setting the number of blank pages (therefore no copy cycle is 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 CPU 201, which sends the status of the master CPU 200 and slave CPU 202, and receives the status of the slave CPU 201. Step 5a is slave 2 CPU 202
control, and sends the status of the master CPU 200 and slave CPU 201, and sends the status of the slave 2 CPU
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 put into the HALT state and all functions are stopped. Further, in step 10b, it is determined whether or not there is a minor abnormality (minor abnormality refers to an abnormality such as paper emptying).If the abnormality is minor, the process proceeds to the next step, and if it is not a minor abnormality, the process proceeds to step 16b. Step 12b is the timing to obtain the end of the current copy cycle, and this t1
If the timing is t12, the process returns to step 2a in FIG. The status is sent to the slave 1 CPU 201, and in step 15b, this status is similarly sent 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 it has not ended, as shown in FIG.
Return to step 7a, and if completed, proceed to the next step. Step 18b indicates that the completed copy cycle is Boo.
It is determined whether the mode is k mode or not. If the mode is not the Book mode, the process proceeds to step 22b, and if the mode is the Book mode, the process proceeds to the next step. In step 19b, it is determined whether or not the page in Book mode is the final page set, and if it is the final page, step 2 in FIG.
Return to step a, and if it is not the last page, proceed to the next step. In step 20b, the page turning command is sent to the slave IC.
The page is sent to the PU 201, and in step 21b it is determined whether or not the 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 returns to step 7a in FIG. 20(a), and then This is what goes into the new copy cycle. Further, in step 22b, it is determined whether or not the mode is A-D-F, and if it is not the mode, the process returns to step 2a of FIG. 20(a).
If the mode is A-D/F, proceed 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 at its end, it is determined as shown in FIG.
Return to step 2a of a) and proceed to the next step if the original is thrown away at the end. In step 24b, the above-mentioned A-D-

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 lh. First, in step lh, RAM and F
ort is initialized, and in step 2h, the status is checked to see if there is any transfer paper on the paper bus of the sorter system or if there is no paper in the intermediate tray, etc., and 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.

This is N-OFF control, and in step 10h it is determined whether or not the copy sequence is for both sides. If not, the process proceeds to step 22h, and if it is for both sides, the process proceeds to the next step. In steps 15h to 14h, route switching SQL is used to change the conveyance path in order to guide the transfer paper to the intermediate tray.
It performs ON/OFF control. Also step 1
From 5h to step 21h, the inversion SQL and the ON/OFF of the inversion roller are used to invert the transfer paper for double-sided copying.
It is control. The process passes through these double-sided control systems and proceeds to step 11 in FIG. 22(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 1
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, the paper ejection 5OLI 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, and if it is not the sorter mode 2, step The process advances to 32h, and if the sorter mode is 2, the process advances to the next step.

The C0PY shown in the figure is repeated.
The cycle number indicates the number of copies. After passing through this processing system, the process proceeds to step 11 in FIG. 22(i).

The flow of b) shows the main processing of the slave 2 CPU 202.

Next, the interrupt processing of the slave CPU 201 will be explained with reference to the flowchart shown in FIG. First, this interrupt processing is generated by one of the control signals from the master CPU 200, and in step 1j, the status of the slave CPU 201 is sent to the master CPU 200 side, and in step 2j, the control signal from the master CPU 200 is transmitted. 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, step 8
Proceed to Retur, which is the end of the corresponding interrupt processing routine.
n instructions are 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 avoid performing 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 performed by master C.
It is generated from one of the control signals from the PU 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 control information from the master CPU 200 is stored in the internal RAM, step 3k
In step 6, it is determined whether or not the sent information contains information on serious abnormalities, and if there is no serious abnormality, step 6 is performed.
Proceed to k, and if there is a serious abnormality, proceed to the next step. In step 4, all loads are turned off, and in step 5k, the system is brought into a HALT 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, step 8 is performed.
Proceeds to Retu, which is the end of the interrupt handling routine.
The rn instruction is executed, and if there is a minor abnormality, information for processing the appropriate load is stored in the internal RAM in order to avoid performing subsequent processing cycles in step 7k, and the relevant interrupt processing is performed in step 8k. The routine ends by executing a Return instruction.
