Abstract

PURPOSE:To save wasteful movements by returning two sets of independently rotating original carrying means to home positions when an original table which can be drawn out of a main body device is not drawn out or when exposure scanning is not being made. CONSTITUTION:A paper feeder 39 is drawn out of a main body device 1 and original paper sheets are placed on the first and second original beds 44 and 42 at the lowered side of a contact glass 14 and exposed, and electronic images are formed on a photosensitive body 22. A sensor S11 detects whether or not there is an original on the paper feeder 39 and a sensor S10 detects the condition of the paper feeder 39 being opened or closed and a sensor S1 detects the home position (HP) of a scanner and sensors 12 - 14 detect the HP condition of the first and second original beds. By the output of these sensors, the scanner and the first, the second original beds 44, 42 are made to return automatically to HPS when the paper feeder 39 is closed and when exposure scanning is not being made though opened. By this, the next exposure can be made immediately, and operation is improved through saving wasteful movements.

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 direction, and after the page is picked up, the page is moved back to the C direction, and this process is repeated.

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 pushed up without wobbling by the pins PI3 and PI3 fixed to the pick-up hands 97 in vertical holes 99i and 99j, respectively.

These states are shown by solid lines.

FIG. 12 shows a layout diagram of the sensors installed in the pickup section. In the figure, S56 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, S59
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, in FIG. 13(a), the first document table 44 and the second document table 42 are raised while the pickup unit is slid toward the Book side, and the roller sensor 358 installed in the pickup hand 97 mentioned above is used to detect the surface of the Book on both sides. is detected, and the first document table 44 and the second document table 42 are stopped at appropriate heights. Next, Figure 13 (
As shown in 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, as shown in FIG. 13(C), the rubber roller 10 for pickup
1 in the winding direction, and further lower the first document table 44 and the second document table 42 a little. Due to these things, when the take-up sensor is turned on as described above, it slides in the direction of the second document table 42 as shown in FIG. 13(d), and after passing the center, it moves at the same speed as the sliding direction. Rotate the pickup 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 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 tray portion 39 is pulled from the main body side, and setting is completed at the position where paper feed roller 40 contacts separating 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 mechanism of the shack for stopping the document in the 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 5OL2, and 1 through the pin of PI3.
There is a plate 1 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 of ~P28 is pushed upward by the diagonal oblong hole 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, which is attached to the second document table main body on one side and the plate member 102 on the other side, turns the shutters 5OL2 and 102 off.
, the plate member 102d is pulled, 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 long sheet documents of 1/2 or less in size. 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 long original sheets of 172 sheets or less. 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 shutter 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.

-F mode control, and slave 2 CPU 202 controls the intermediate tray and sorter.

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 normal number of copies.
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 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
It is a control of the master CPU 200 and slave CPU 201+7), and sends the status of the slave 2C.
It receives the status of the PU 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 steps are performed. enters copy cycle mode. Step 7a is the step 4a
, and step 8a is the same as step 5a, so the explanation thereof will be omitted. (Step 9a counts the drum clock and scan clock necessary for sequence control, and step 10a
is to control the fixing device within a temperature range that allows fixing. Next, step 11 mill step 32a and steps 20 to 3b in FIG. 20(b) are for carrying out ON-OFF control of each load as shown in the figure, 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, in step 7b, this state is sent to the slave 1 CPU 201, and in step 8b, this state is similarly sent to the slave 2 CPU 201.
It is sent to U202, and in step 9b it is put into the HALT state and all functions are stopped. Further, in step 10b, it is determined whether there is a minor abnormality (minor abnormality indicates an abnormality such as paper emptying), and if it is a minor abnormality, the process proceeds to the next step, and if not, the process proceeds to step 16b. Step 12b is the timing to obtain the end of the current copy cycle, and if this timing is t12, step 2 in FIG. 20(a)
Return to a, and if it is outside the t12 timing, step 13b
In step 14b, this state is sent to the slave 1 CPU 201, and in step 15b, this state 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, as shown in FIG.
Return to step 7a of a), and if completed, proceed to the next step. Step 18b indicates that the completed copy cycle is B.
It is determined whether the mode is Book mode or not, and if it is not Book mode, the process proceeds to step 22b, and if it is 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. 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 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 second
The process returns to step 7a in FIG. 0(a), and a new copy cycle begins. 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 not finished. In step 24b, the above-mentioned A-D

Also, in this mode 4, the belt motor l side is rotated at an appropriate timing for paper ejection (when the exposure optical system returns), but this part is not shown in the flow chart because it seems that there is no particular problem. 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 lh, RAM and Po
rt 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.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. If not, the process proceeds to step 10h, and if double-sided copying, the process proceeds to the next step. In steps 6h to 9h, the paper feed roller of the intermediate tray is turned on by referring to the drum clock.
- OFF control; step 10h determines whether the copy sequence is for both sides; if it is not for both sides, proceed to step 22h; if it is for both sides, proceed to the next step.

Step 6h - ON-OFF control of the route switching SOL for changing the step bus is performed. Also, step 15h to step 21
The steps up to h are the reversal SQL for reversing the transfer paper for double-sided copying and the ON/OFF control of the reversing roller. After passing through the control system for both sides, step 1 in Fig. 22(i)
Go to 1.

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, 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. The process proceeds to step 32h, and if the sorter mode is 2, the process proceeds to the next step.

In steps 25h to 31h, in order to eject the paper to the paper ejection tray 13b and later, the paper ejection 5OL2 and the subsequent ones are repeatedly turned on and off from the top according to the number of copies, and A and B shown in the figure are A and B. In the case of B, the value of the number of copies is shown, and in the case of B, the timing data is shown.

After passing through these processing systems, step li in FIG. 22(i)
Proceed to. Also, step 32h is the processing of sorter mode 3.
Then, the paper output 5OL for discharging the paper to the paper output tray 13b and subsequent ones.
Turn on/off 2 and later according to the number of copies from the top.
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).

Next, the explanation of step 1j in FIG. 22(b) will be continued.

First, in step 11, it is determined whether the copy cycle is at the end or not. If it is not at the end, as shown in FIG.
Return to step 5h, and if it is the end, proceed to the next step. In step 21, the SQL shown in Figure 22 (h)
22(a), and return to step 2h in FIG. 22(a). As explained above, FIGS. 22(a) and 22(
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 state of the slave CPU 201 is sent to the master CPU 200 side, and in step 2j, the state of the slave CPU 201 is sent to the master CPU 200 side.

Control information from the star CPU 200 is stored in the internal RAM.
Then, in step 3j, it is determined whether or not the information sent out includes information on a serious abnormality. If there is no serious abnormality, the process proceeds to step 6j, and if it is a serious abnormality, the process proceeds to the next 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 information about a minor abnormality is included in the above-mentioned information, and if there is no minor abnormality, the process proceeds to step 8J and executes the Return instruction, which is the end of the interrupt processing routine, and If so, 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, a Return instruction is executed to end the interrupt processing routine. Executes and ends. 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 lk, the state of the slave 2 CPU 202 is controlled by the master CPU 200.
The control information from the master CPU 200 is sent to the PU 200 side in step 2k, and the control information from the master CPU 200 is stored in the internal RAM.In step 3k, it is determined whether or not the sent information contains information on a serious abnormality, and the information is detected as a serious abnormality. If not, proceed to step 6k, and if it 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, the process proceeds to step 8, and a Return instruction is executed, which is the end of the interrupt processing routine. , if there is a minor abnormality, in step 7k, information for processing the appropriate load is stored in the internal RAM in order to avoid performing subsequent processing cycles, and in step 8k, the interrupt handling routine ends. The Return instruction is executed and the process ends.
