Description

[Detailed description of the invention]

[Industrial Application Field] The present invention is equipped with or connected to an image forming apparatus such as a printing machine, a copying machine, a facsimile machine, and a laser printer, and conveys a sheet that has been processed in some way by these devices to a desired sheet. The present invention relates to a sheet deflecting device that deflects the conveying direction of sheets in order to distribute and convey them to a road, a sheet storage device, or the like. [Prior Art] In recent years, many image forming apparatuses not only perform image formation, but also have various functions associated with image formation. These functions include, for example, double-sided compositing,
These processes include reversing, collating, binding, and folding, and when performing these processes, it is necessary to transport the sheet on which images have been formed from the transport path that is used to transport the sheet immediately after image formation to the point where these processes are performed. . Therefore, it is necessary to change the conveyance direction of the sheet at a certain position and select one of the plurality of conveyance paths to carry out the above processing and feed the sheet. In order to change the conveyance direction of the sheet and send it to the desired conveyance path, conventionally, a movable branching pawl is used, and the leading edge of the sheet is pinched or engaged with the pawl, and the sheet is conveyed as desired. It was set to lead to the entrance of the road. [Problem to be Solved by the Invention] However, when the branch claws are used in this way, the edge of each sheet must be reliably pinched and conveyed, which inevitably complicates the sheet gripping structure. As a result, the mechanism becomes larger. Furthermore, a large number of sheets must be processed, and if the edges of each sheet are securely pinched, the time required to process each sheet increases, which limits processing efficiency. That is, in the conventional example described above, the mechanism becomes complicated and large, which not only increases the cost of the device but also reduces reliability. Further, since there is a limit to the processing efficiency, the productivity in image formation is also determined by the sheet processing speed, and there is also the problem that the productivity of the image forming apparatus as a whole is poor. The present invention has been made in view of the actual state of the prior art, and its purpose is to provide a sheet deflection device with a simple structure, small size, low cost, and high productivity. [Means for Solving the Problems] The above object is to provide a conveyance path between at least one conveyance path for conveying a sheet and a plurality of conveyance paths located downstream of this conveyance path in the sheet conveyance direction; - In a sheet deflecting device that switches a sheet conveyed along one conveyance path to one of a plurality of conveyance paths and conveys the sheet, a guide means in which at least one sheet guide path is formed and the guide means is driven. This is achieved by comprising a drive means, and a control means for driving and controlling the drive means so that the sheet guide path communicates between a conveyance path on the upstream side in the sheet conveyance direction and a desired conveyance path on the downstream side in the sheet conveyance direction. Ru. Further, in that case, it is desirable for control to further include a guide path detection means for detecting the position of the sheet guide path. [Function] According to the above, the sheet that has completed the predetermined image formation and has been conveyed from the conveyance path upstream of the sheet deflection device in the sheet conveyance direction to the sheet deflection device enters the guide path of the guide means. At this time, the guide means is driven by the drive means via the control means such that the exit of the guide path faces the entrance of a desired conveyance path on the downstream side in the sheet conveyance direction. For this reason,
The sheet is conveyed through an upstream conveyance path, a guide path, and a downstream conveyance path. Therefore, the sheet can be deflected by simply moving the guide means in which the guide path is formed. In this case, in order to ensure positional accuracy, the M stacking means can be set to perform drive control of the driving means with reference to the output from the guide path detection means for detecting the inner path of the sheet X. In this specification, explanations related to the above-mentioned means and effects of the present invention are mainly explained below.

03) to open the document bin 201.
a Geneva wheel 207 that moves either one of them to the document feeding position, and a bottom plate 21 that pushes up the document 69 placed in the document bin 201 toward the calling roller 209 during document feeding.
) and separation rollers 21 provided along the conveyance path 213.
5 and a pullout (registration) roller 217 that defines the timing of conveyance of the leading end of the original W169. The document bin 201 has upper and lower bin guide paths 220 and 221 that are provided substantially perpendicularly partially opposite to the rotation locus of a notch 219 formed in the Geneva wheel 207.
The stopper 203 is set to engage and guide the Geneva wheel 2 along the lower bottle guide path 221.
A bin switching pawl 223 is provided on the center side of the document bin 201 for separating each document bin 201 from the Geneva wheel 207 and guiding it to the lower bin guide path 221. A bottom plate lifting hole 225 is formed at a position adjacent to the stopper 203 of each document bin 201 so that the bottom plate 21) can push up the document 69 placed on the document bin 201. Further, at the lowest part of the lower bottle guide path 221, there is a push-up member 22 for constantly elastically urging the stopper 203 located in the bottle guide path 221 upward by a tension spring 227.
9 is installed. The Geneva wheel 207 is rotated in forward and reverse directions by a wheel motor 231 consisting of a stepping motor. The pick-up roller 209 and the separation roller 215 are rotationally driven by a transport motor 233 via a pick-up roller drive bell) 210 and a separation roller drive belt 216, respectively, and the driving force of the transport motor 233 is transmitted to the pull-out roller 217 via a gear 235. The signal is transmitted to a registration clutch 237 that performs drive control. This resist clutch 2
37 is driven by a resist solenoid 238. Furthermore, further below the lower bottle guide path 221,
Bin switching solenoid 240 that drives the bin switching claw 223
is installed. The bottom plate 21) is swing-driven by a bottom plate drive arm 239, which is driven by a bottom plate drive motor 24 that can rotate in forward and reverse directions.
1. Moreover, along the conveyance route 213,
a leading edge detection sensor 243 that detects the leading edge position of the document 69;
A registration detection sensor 245 for detecting the registration state of the original 69 is provided, and is located at a position along the upper bin guide path 220 and at a position corresponding to the upper surface of the original bin 201 when it enters the paper feed port 247 side. A document set detection sensor 249 is provided to detect whether the document bin 201 is set. A bottom plate home position sensor 251 is disposed below the bottom plate 21) for detecting the home position evacuated from the bottom plate lifting hole 225 of the document bin 201, and further detects the standby home position of the Geneva wheel 207 and the Standby home position sensor 25 for detecting paper home position
7 and a paper feed home position sensor 259 are provided at positions facing the Geneva wheel 207. Each of these mechanisms connects to the document bin 2 via guide paths 220 and 221.
It is housed in a side plate 261 that supports 01. FIGS. 4(b) and (C1 are explanatory diagrams illustrating the elevating and lowering operations of the document bin 201 and the moving operation to the document feeding position. The group of document bins 201 is in the initial position in FIG. 4fa)
As shown in the figure, the five-stage document bins 201a to 201e and the dummy bin (corresponding to the push-up member 229) are located two places below the Geneva wheel 207, and are always maintained by a tension spring 227 that elastically biases the push-up member 229. Forced upward;
The first document bin 201a is in pressure contact with the outer periphery of the Geneva wheel 207. In addition, the bin switching claw 223 is in a downward state. When the wheel motor 231 rotates counterclockwise in the drawing from this state, the Geneva wheel 207 is also rotated counterclockwise by the wheel motor 231. When the notch 219 provided in the Geneva wheel 207 comes to a position facing the stopper 203a of the document bin 201a, the elastic force of the tension spring 227 causes the stopper 203a to
fits into the notch 219. During this time Geneva Wheel 20
7 continues to rotate, the document bin 201a remains in the notch 21 as the Geneva wheel 207 rotates.
It rises along the rotation trajectory of 9. When the document bin 201C comes to the paper feed home position sensor position due to this rise, the paper feed home position sensor 259 detects this. This detection output stops the wheel motor 231 (this position is the A4 position in FIG. 4('b) showing the operation of the third-stage document bin 201C), and this time it rotates in the opposite direction, that is, clockwise. . Along with this rotation, the Geneva wheel 207 also rotates clockwise, and the document bin 207 also rotates clockwise.
With the stopper 203a of 01a engaged, the document bin 201a is advanced toward the document feeding position. During this rotation process, the stopper 203a engaged with the notch 219 moves to the B4 position without separating from the notch 219 when the stopper 203a comes to a position facing the lower bottle guide path 221. The stopper 203b of the second-stage document bin 201b waits at the opening of the lower bin guide path 221 while being elastically biased upward, and the bin guide path 221 is closed by the next-stage bin. This is because that. When the document bin 201a is advanced toward the document feeding position in this manner, the document set detection sensor 249 detects the document setting position, that is, the document feeding position, and stops the wheel motor 231 (this position (This is the B4 position in Figure 4, which shows the operation of the first original document bin 201C).
. This means that the document bin 201a has been set at the document feeding position. In this way, the document bin 201a
is set at the document feeding position, the bottom plate lifting motor 241 starts rotating as described later, raises the bottom plate 21) and presses the document 69 against the calling roller 209, making it possible to feed the document 69. Become. When the job for the first document bin 201a is completed in this way, the document bin for the next job is selected according to the mode input in advance. Therefore, it is necessary to save the document bin 201a after the job has been completed. This retracting operation is performed by rotating the wheel motor 231 counterclockwise from the document feeding position (B a position). That is, when the wheel motor 231 rotates counterclockwise, the Gene/NJ wheel 207 also rotates in the same direction, and in conjunction with this rotation, the stop collar 203a of the document bin 201a is moved in the same direction. As a result, when you return to position A,
This time, the upper bottle guide path 220 is open, and when the stopper 203a engages with the opening, it is removed from the notch 219 of the Geneva wheel 207. Then, the notch 219 is rotated counterclockwise until the notch 219 is at a position opposite to the stopper 203b of the document bin 201b located at the upper end of the lower bin guide path 220, and the stopper 203b is fitted into the notch 219. The document bin 201b is then engaged with the original document feeding position or the upper bin guide path 220 by a similar operation. When returning the document bin 201 located in the upper bin guide path 220 to the lower bin guide path 221 in this manner, the wheel motor 231 is rotated clockwise and the Geneva wheel 207 is rotated in the same direction. Then, the notch 219 of the Geneva wheel 207 is connected to the upper bin guide path 220.
When the document bin 201 is in a position opposite to the opening of the
strike. The pad 203 falls into the notch 219 due to its weight and engages therein. On the other hand, the bin switching pawl 223, which had been retracted from the rotational trajectory of the Geneva wheel 207, is raised by a driving means (not shown) to a position where it interrupts the rotational trajectory of the notch 219, as shown in FIG. 4(C). As a result, the stopper 203, which has descended while rotating clockwise while being engaged with the stopper 203, moves toward the lower bottle guide path 222.
When the bin switching claw 2 reaches the position facing the opening of
23. Due to this contact, the stopper 203 is pressed against the contact surface of the bin switching claw 223,
Furthermore, it moves downward along the lower bottle guide path 221 against the elastic biasing force of the tension spring 227, and the notch 219
depart from. When removed in this manner, the outer peripheral surface of the Geneva wheel 207 comes into contact with the stopper 203, so the stopper 203 does not separate from the lower bin guide path 221. This state is the state shown in FIG. 4(C). FIG. 5 is a schematic explanatory diagram showing a mechanism for raising the bottom plate. In the figure, three bottom plates 21) are provided for the bottom plate lifting arm 229, and are advanced from below the document bin 201 onto the document bin 201 by the bottom plate lift motor 241, and push the document 69 toward the calling roller 209 side. When the document bin 201 is placed in the paper feeding position, the bottom plate lifting motor 241 starts rotating and the bottom plate 21) is lifted. The original 69 lifted by the bottom plate lifting motor 241 is
It comes into contact with the calling roller 209, and in this state, the calling roller 209 is slightly lifted. Then, the rise detection shielding plate 265 releases the shielding state of the rise detection sensor 263 (

65 gradually rises (in the direction of arrow B), rising detection sensor 2
63, the bottom plate lifting motor 241 is turned ONL again.
, the original 69 is raised. The rotation speed of the bottom plate lifting motor 241 is determined by two gears.
The speed is reduced to about 1/10. This is the bottom plate lift motor 24
This is to increase the torque of 1 through the gear and to slowly lift the document 69 to increase the detection accuracy of the upper limit detection sensor 263. In addition, the first gear of the bottom plate lifting motor 241 is equipped with a worm gear. This is to prevent a force in the reverse direction from acting on the sector gear 235 due to the weight of the documents in the document bin 201. FIG. 6 shows the relationship between the calling roller 209 and the separating roller 215. A schematic explanatory diagram, FIG. 7 is a schematic configuration diagram showing the structure near the pull-out roller 217, and FIG. 8 is a diagram showing the structure of the pull-out roller 217.
09 is an explanatory diagram showing the vicinity of 09. FIG. In these figures,
After inserting the original 69, when the print key 663 of the copying machine 1 is pressed, the call solenoid 267 is turned on. When the call solenoid 267 is turned on, the plunger is pulled, and the actuating shaft 269 and the assembly 271 of the actuating lever 270 fixed to the actuating shaft 269 rotate in the direction of arrow C, and the calling roller 209 descends to the document 69. In close contact. Next, the conveyance motor 233 is turned on, and the signal is transmitted to the separation roller 215 via the separation roller drive belt 216, so that the separation roller 215 rotates. This rotational driving force is transmitted to the calling roller 209 via the calling roller drive belt 210, the calling roller 209 rotates, and the document 69 is fed. In addition, the registration solenoid 238 is connected to the transport motor 233O.
Since it turns on at the same time as N, the driving force of the transport motor 233 is transmitted to the registration clutch 237, and further
The pull-out roller 217 rotates, and the document 6
9 is sent to the document transport unit 51. The registration clutch 237 uses a spring clutch, and when the original 69 is sent to the original transport unit 51 and the registration detection sensor 245 is turned OFF, the registration solenoid 23 is activated.
8 is also 0FFL, resist clutch 23 by stopper claw
7 stops, the pullout roller 217 also stops,
: Feeding of the original 69 is stopped. Note that in the automatic document feed mode (ADF mode), the call solenoid 267 goes to 0FFL when the leading edge detection sensor 243 is turned ON by the document 69, and in the semi-automatic document feed mode (SADF mode), the registration detection sensor 245 is turned ON. This turns the calling solenoid OFF. The separation roller 215 separates the document 69, and as shown in the front view of FIG. When referring to a roller, step portions are formed alternately in the circumferential direction of the roller (with reference numeral 215), and the step portions are formed so as to bite into the different steps. As a result, manuscript 6
9 are separated by frictional force to improve document conveyance and prevent double feeding. In order to improve the conveyance of the document 69, the separation roller 215 is operated by an operating lever provided at one end of the support shaft 273 of the lower separation roller 215b when the document 69 faces the separation roller 215, as shown in FIG. The lower separating roller 2 rotates in the feeding direction by the rotation of 275 to securely hold the document 69.
15b, while the conveyance motor 233 is turned on in order to prevent wear of the separation roller 215 and double feeding of the documents 69,
It's rotating backwards little by little. When the conveyance motor 233 is turned on, its drive is transmitted to the upper separation roller 215a via the separation drive gear 277. The boss portion of the separation drive gear 277 is an eccentric cam, as shown in FIG. 10 and FIG. A one-way clutch 279 is press-fitted into the 0 actuation lever 275, which swings along the cam shape, and when the actuation lever 275 moves upward, the lower separation roller 215b also rotates. In order to prevent these separation rollers 215 from being stained by originals such as pencil originals, the gap between the separation rollers 215 is released every time a copy is made to prevent smearing. That is, the first
As shown in FIG. 2, the release shaft 28 has a separation roller release eccentric cam 281 attached to the upper separation roller 215a.
2 is attached, and the eccentric cam 281 is attached to the recess 2 of the adjustment plate 283.
I'm stuck in 84. The other end of this adjustment plate 283 is fitted onto the shaft of the lower separation roller 215b. Further, another eccentric cam 278 is provided at one end of the release shaft 282,
It can be driven by the lever 276 of the separation roller release solenoid 285. With this configuration, when the separation roller release solenoid 285 is turned on, the plunge portion of the solenoid 285 is sucked, thereby operating the lever 276 and rotating the eccentric cam 278. This rotation causes the release shaft 282 to also rotate, and the rotation of the release shaft 282 also causes the separation roller release eccentric cam 281 to rotate. Then, the adjustment plate 283 is moved to the support shaft 286 by the rotation of the separation roller release eccentric cam 281.
The lower separation roller 215b moves downward, and the gap between the upper and lower separation rollers 215 is released. 13 to 16 are explanatory diagrams showing details of the transport section of the document transport unit 51, in other words, the opening (lift)/close detection of the pressure plate 288. As shown in FIG. 13, the document conveyance unit 51 is provided with a sensor 289 for detecting the setting of the pressure plate 288. This set detection sensor 28
9 is a microswitch, and when the tip of an arm 291 protruding from the base 290 lowers the pressure plate 288,
As shown in FIG. 14, the movable end of the micro-sinch 289 is pressed to turn on, and the setting of the pressure plate 288 is detected. When centering the pressure plate 288, a spring 292 is used in this embodiment instead of the general pressure plate.

[5. Overall Control Concept] The control performed by combining the respective sections configured as described above will be schematically explained. Although the figure is skipped, a conceptual diagram of the control is shown in FIG. 134. As can be seen from this figure, the copying machine main body 1, the multi-stage ADF 49, and the finisher 1) each perform various checks or processes when the power is turned on. That is, in the copying machine main body 1, the initial processing 13 is first performed.
4-1 is executed, and then standby processing 134-2, pre-processing and copying processing 134-3, and post-processing 134-4 are executed, respectively. An error mode 134-5, typified by error check, is set for each of these processes, so that it can handle various types of errors.

[6. Operation Side of Each Part The respective parts configured as described above and the control of the overall operation of the copying machine system formed by these parts will be described with reference to flowcharts. (6.1 Overall General Control) Since the copying machine 1 according to this embodiment is equipped with a five-stage multi-stage ADF 49 on the document feeding side, it is possible to sequentially execute a plurality of jobs. In other words, a plurality of jobs (up to five in the embodiment) are input as a reservation mode, and the input is memorized to select the copy execution order and perform processing according to the job contents so as to increase copy productivity. Can be set to Naturally, the normal copy mode can also be selected, and the reservation mode and normal copy mode are selected using non-volatile RAM data or a depth inch on the printed wiring board. Processing in the reservation mode and normal mode includes copy operation processing, copy ejection processing, and document processing. In the copy operation process, a copy operation is performed according to the set mode in both the reservation mode and the normal mode. In copy ejection post-processing, sorting,
Performs stable and other processing.In addition, in sort mode, the bottom bin of the 20 bins of finisher 1) is
The topmost bin is the first bin in the staple mode. In document processing, documents are discharged to a shift tray 392, a sorting bin (sheet storage bin 57), or the like according to a preset mode. When discharging onto the sort bin, this process is executed after all copy discharging processes are completed. (6,2 Reservation mode) Reservation mode means setting multiple jobs in advance and
This is a mode in which the start timing etc. of the copying operation are determined and executed on the copying machine side, and the job processing method and other aspects are the same as normal copying operations. As a condition for setting reservation mode, ■ Peripheral devices (
(Each option group) is specified, and ■ Reservation mode is selected. In this case, the condition (2) is determined based on whether each option group is connected online through serial communication. If this condition is satisfied, both the reservation mode and the normal copy mode can be selected and executed, so as mentioned above, either one can be selected by using means such as rewriting the data in the non-volatile RAM 577 or using the depth inch on the printed wiring board. select.

Details of the processing at this time will be explained with reference to the flowcharts of FIGS. 50 and 51. FIG. 50 shows the processing procedure for setting the reservation mode. After executing the subroutine for serial transmission/reception processing with the peripheral device in step 550-1, check whether the finisher 1) is connected (step 55Q-2, hereinafter referred to as step 55Q-2). , the word "step" is omitted in parentheses), whether the document is connected to the document stacking unit 52 (S50-3), whether the multi-tier unit 50 is connected (350-4), whether the document reversing unit, step 52 is connected, etc. It is determined whether they are connected (S50-5), and if all are connected, the setting of the reservation mode is permitted in step 550-6, and the process returns. In addition, if there is a peripheral device that is not connected in each of steps 550-2 to 350-5, step 5
At 50-7, setting of the reservation mode is prohibited and the process returns. Then, the process moves to the process shown in FIG. 51, and if the reservation mode setting is permitted in step 551-i, step S51
Select the reservation mode with -2. This reservation mode can also be selected using the nonvolatile RAM 577, dip switch, or other means as described above. and,
If the reservation mode is selected, copy control is executed in the reservation mode in step 351-3, and step 551)
If the reservation mode setting is not permitted in step 551-2, and if the reservation mode is not selected in step 551-2, copying is performed by normal key manual processing in step 551-4. Note that when the reservation mode is selected in step S51-2, inputting, changing, and clearing the reservation mode job requires inputting a three-digit number (reciting code). This is to prevent the job from being cleared or changed by other operators. The processing at this time will be specifically explained with reference to FIG. In this process, first, it is determined whether the reservation mode key is turned on. The reservation mode key 661 is connected to the print key 66 as shown in the front view of the main part of the operation section in FIG.

59-21), then return. FIG. 54 is a memory map schematically showing the code data stored in this memory. Note that in step 552-18, the enter key 6 is pressed.
When it is determined that 73 is OFF, the process directly returns. If the mode clear key 665 is turned on as determined in step 552-15, step 552-2
2 mode clear processing is performed and the enter key 673 is set to O.
It is determined whether the answer is N (S52-23). If the enter key 673 is turned on as determined in this step, step 55 determines whether the timer start flag is set.
If it is determined in step 2-24, it is further determined in step 552-25 whether timer 1 is counting up.
Judge by. If the timer l is counting up, clear the mode setting corresponding to the key selected by the reservation selection key 671 (552-26).
, turn off the corresponding LED 675 552-27), and turn off the reservation LED 677 (S52-28>, then lower the code input flag (S52-29). Next, stop timer 1 and clear it 552-30), The timer 1 start flag is lowered (S52-31) and the process returns. Incidentally, if the enter key 673 is OFF as determined in step 552-23, the processing from step 552-30 onwards is executed as is. Further, when it is determined in step 552-23 that the timer start flag is not set, the 0°5 second timer 1 is started and the timer 1 start flag is set (S5
2-32) Return and when it is determined in steps S52 to S25 that timer 1 has not counted up,
Return as is. If the determination in step 552-14 is that the mode check process has not yet been completed, step 552
-33, checks to see if the number of sheets has been exceeded for each mode and displays the check status, and if the mode clear key -665 is turned on (YES in S52-34), step The process after the mode clear process in step 552-22 is executed, and if it remains OFF (No in S52-34), the process after step 552-12 is executed. Further, if the LED 675 selected by the reservation selection key 671 in step 552-7 is ON, it is determined whether the LED 675 is blinking (352-35). LED
675 is turned off (S52-36), and the 3-digit code data in the memory is cleared (S52-37). After that, after lowering the code input flag 552-38) and clearing all modes (S52-39), the reservation LED 677
blinks (S52-40) and returns. On the other hand, if it is determined in step 552-35 that the LED 675 is not blinking, the 3-digit code data is loaded from the memory (352-41) and the input 3-digit code and the 3-digit code loaded from the memory are (S52-42), and when it is determined in this step 552-42 that they match, the LED 675 corresponding to the key to be selected is blinked (S52-43); The mode data stored in the memory is loaded (552-44), and settings are made according to the mode data (S52-45). Then, a code input flag is set (S52-46), and the LE corresponding to the selection target is
Turn on D675 (352-47). Thereafter, the processing from step 552-13 onwards is executed. Furthermore, if it is determined in step 552-42 that the codes do not match, the process moves to steps 552-48 and subsequent steps, which will be described later. Incidentally, before proceeding to the processing from step 552-48 onward, the reservation error LED 679 and other display elements may be set to be lit for a certain period of time. Further, if the mode clear key 665 is turned on in step 352-5, the key input of the 3-digit recitation code is cleared (S52-48) and the process returns. In addition, the target reservation selection key 671 is turned OFF in step 552-6.
If so, just return. Furthermore, the reservation LED 677 is turned on in step 552-2.
If it is determined that the
Check that the reservation LED 677 is blinking in step 9, and if it is lit without blinking, turn off the selected LED 675 (552-50), and clear the 3-digit code data in the memory (S52-51). Set the code input flag to 0 (S52-52), then execute a subroutine to clear all reservation modes (S52-53) and set the reservation LED

The original is set on the paper 205. Then, an execution job is selected and executed according to each reservation mode. (6,3 Execution of Reservation Mode Jobs) When the copying machine 1 is in the reservation mode and in the standby state, the execution order of the five reservation modes (jobs) is determined by the following factors.・If all are in stable mode, the order in which they were entered is correct. - In the non-stable mode, if the next job can be executed with the number of empty sheet storage bins in the finisher 1, that is, the number of bins not used in the non-stable mode, the non-stable mode is executed. In this embodiment, in the non-stable mode, the sheet storage bin 5 of the finisher 1) is
It is set to exist on 7. This is intended to allow the operator to remove the sheet from the storage bin 57 during that time. However, if the sheet is left on the sheet storage bin 57 for more than 5 minutes, the execution of the next job will be delayed, so in this embodiment, the job is stabilized after 5 minutes, the sheet is sent to the stack tray 67, and the sheet is sent to the sheet storage bin 57. 57 to an empty state so that other jobs can be executed. Therefore, the processing time of the entire job is determined by how the five minutes are utilized. FIG. 55 is an explanatory diagram showing the relationship between job reservation and execution in the reservation mode. This figure shows the order in which reserved jobs are accepted, the reserved mode, the number of bins to be used, the number of bins with remaining sheets, and the execution order of reserved jobs. The following modes are set for this reserved job. 1) (Al copy staples 5 copies etc.) The original is also stable (C) The number of bins used is 5 (d) The number of bins with remaining sheets is 0 2) (a) Copy sorting 8 copies (b) Originals are sorted in the sorting bin jcl The number of bins used is 8 + 1 (d) The number of bins with sheets remaining is 9 3) + 8 + 5 copies of stable copies (BL original is also stable (C) The number of bins used is 5 (d) The number of bins with sheets remaining is 9) 0 4) (Al copy sorting 15 copies (b) The original is on the shift tray (C) The number of bins used is 15 (The number of bins where the DL sheet remains is 15 5) (a!

The order of execution is shown in the rightmost column of FIG. Note that the completed jobs are shifted in order as shown in FIG. Processing for executing these reserved jobs will be described in detail with reference to flowcharts. FIG. 57 is a flowchart showing a procedure for determining the execution order of jobs in reservation mode. In this procedure, first, in step 357-1, it is determined whether any of the keys P1 to P5 of the reservation selection key 671 is turned on. If it is ON, step 557-
In step 2, the mode data and number data set by the reservation selection key that has been turned ON are called up. Then, it is determined whether the stable mode is set or not based on whether the stable mode flag is set.S57-
3) If the mode is not stable mode, it is further determined whether the mode is sort mode based on the sort mode flag (S57).
-4). If it is in the sort mode, it sets the number data representing the number of copies in the remaining paper pin counter (557-5) and sets a sort flag (S57-6). Next, the stable flag is lowered (S57-7), and number data indicating the number of copies is set in the used pin counter. If it is determined that the stable mode is set in step 557-3, the remaining paper pin counter is reset (S57-9), the staple flag is set (357-10), and the sort flag is lowered. (
After S57-1)), the process proceeds to step 557-8. When the process of step 557-8 is completed, the O
It is determined whether the RG sort mode flag is set (S57-12). If the sort mode flag is not set in step 557-4, the staple flag (S57-13) and the sort mode flag (S57-14) are lowered, and the remaining paper pin counter and used pin counter are set. After resetting (S57-15), it is determined whether the sort mode flag is set (S57-12). Step 1. If it is determined in step 557-12 that the ORG sort mode flag remains down, set the ○RG sort flag to O (S 57-IG), and press keys PI to P5 of the target reservation selection key 671. FPOH7 dress number in binary (P○ is PL, P2.P3

-20). Then, it is difficult to determine whether the remaining paper pin counter is larger than 20 (557-21), and if it is larger, 20 is set in the remaining paper pin counter (35
7-22). Next, it is determined whether the used pin counter is larger than 20 (55723), and if it is, 20 is added to the used pin counter. Note that when it is determined in step 557-21 that the remaining paper pin counter is 20 or less, and in step 557-23,
When it is determined that the used pin counter is 20 or less, the process jumps to the next step and executes the next process.After executing the process of step S5717, the process returns. Note that the upper three bits of the FPOH address in step 557-17 mentioned above refer to the ORG sort flag and FPMQHI x x x P○. =20 bins (5 bits)-= ↑ Remaining paper bin counter Also, step 557-2. Step 557-17 and the above P○ indicate the state of the reservation mode selected by the reservation selection key 671 (PL. 2.3, 4.5). As shown in the flowchart of FIG. 58, job selection begins by first determining the state of the job selection memory. Job selection memory is 0 in step 35B-1
If not, return; if 0, step 358-2
It is determined whether the staple flag of FPMIL is set, and if it is set, the numerical value of the number (Pi to 5) of the job to be executed first is stored in the upper four bits of the job selection memory at step 35B-10. A staple flag is transmitted from the CPU 573 on the copying machine 1 side, and is set to "1" to indicate execution of the stapling operation. If the staple flag is not set in step 35B-2, step 35B-
In step 3, it is determined whether the FPMIL sort flag is set, and if it is not set, the process of step 35B-10 is performed, and if it is set, the remaining sheet pin counter of FPMIL and the used bin counter of FPMIL are called in step 35B-4. . Next, in step 55B-5, it is determined whether the sum of the number of used pin counters of FPMIH and the number of used pin counters of FPMLL is 20 or less. If it is less than 20, the process of step 35B-io is executed; if it is greater than 20, it is determined in step 558-6 whether the staple flag of the FPM 2L of the second job is set. If it is set, that is, if stapling is to be performed, 2 bits are stored in the upper 4 bits of the job selection memory.
Job number corresponding to the th job (Pi to 5)
Stores the value of and returns. If the stable flag is off in step 558-6, it is determined in step 5ss-s whether the stable flag of FPM3L of the third job is on, and if it is, the stable flag of the job corresponding to the third job is Stores the numerical value of the number in the job selection memory and returns. Furthermore, if the vehicle has descended, the process of step 358-10 is executed and the process returns. (Processing by 6, 4 Original Processing Keys) FIG. 59 shows an example of the display of the mode selection keys and the selected mode. A copy processing key 701 and a document processing key 703 are respectively provided, and above them there is a stable display. Mode display LED 701a, sort mode display LED 70

c are provided respectively. Therefore, in the mode set by the document processing key 703, the CP
U573 first checks the finisher connection flag and document reversing unit connection flag (S60-1. Step 360-2). If each connection flag is 0, that is, if either the finisher or document reversing unit is not connected, return; if connected, step 56
At 0-3, it is determined whether the reservation mode setting is completed. If the reservation mode is in the process of being set, the process returns; if the reservation mode has been set, step 560-4
Now let's determine whether interrupt mode is enabled. If it is not the interrupt mode, it is further determined in step 360-5 whether the document processing key 703 is turned on. If the document processing key 703 is turned on as determined in step 560-5, stable mode is displayed in step 560-6.
Determine whether ED703a is turned on. If the document processing key 703 is not turned ON in the determination at step 560-5, it is determined whether the stapling prohibition flag is set (560-14), and if the flag is set, that is, stapling is prohibited. If so, the process returns, and if the stable prohibition flag is off, it is determined whether the reservation mode is set (S60-
15) If it is determined in step 56015 that the mode is not in the reservation mode, the process returns; if it is in the reservation mode, it is determined whether the mode is in the sort bin mode (S60
-16). If it is determined in step 560-16 that the mode is the sort bin mode, the process returns; if the mode is not the sort bin mode, it is determined whether the shift tray mode is selected (360-17). If the shift tray mode is set in step 360-17, the process returns; if not, the stable (ORG) mode subroutine shown in the flowchart of FIG. 62, which will be described later, is executed (S60-18) and the process returns. Furthermore, if the stable mode display LED 703a is ON in the judgment at step 560-6, the 63rd
The sort bin mode subroutine shown in the flowchart of the figure is executed (560-19). Also, if the stable mode display LED 703a is not turned on, the sort bin mode display LED 703b is turned on.

If b is not ON, then it is determined whether the shifted L mode display LED 703 is set to cMON (S60-8). If the shift tray mode display LED 703c is ON as determined in step 560-8, it is further determined whether the reservation mode is set (560-9). If the reservation mode is not set in step 560-9, the normal mode subroutine shown in the flowchart of FIG. 61 described later is executed (

The process jumps to step 0-8 and executes the process from step 560-9 onwards, and if the document stacking unit 52 is connected, the shift tray mode subroutine shown in the flowchart of FIG. 64, which will be described later, is executed ( S60-1
3) After that, return. Note that when it is determined in step 560-4 that the mode is not interrupt mode, and when it is determined in step 560-8 that the shift tray mode display LED 703C is in the OFF state, the normal mode subroutine of step 560-10 is directly executed. Execute and return. The normal mode subroutine in step 560-10 described above is processing as shown in the flowchart of FIG. 61. This process sets the stable mode flag, sort bin mode flag, and shift tray mode flag to 0.561-1, 561-2.361

Then, the shift tray mode display LED 703C is turned off (S62-8) and the process returns. Note that if it is determined in step 562-2 that the mode is reservation mode, and if it is determined that there are no remaining sheets in the sheet storage bin 57, the process jumps to step 562-5 and the subsequent processes are executed. The sort bin mode subroutine in step 560-19 described above is the process shown in the flowchart of FIG. 63. In this process, first, it is determined whether it is in reservation mode (563-1), and if it is in reservation mode,
A guidance display stating "The job will be stabilized 5 minutes after the end of the job" is displayed (S63-2), and the stable mode flag is set (S63-3) to cancel the stable mode. Then, the sort bin mode flag is further raised (363-4) to set the sort bin mode, and the shift tray mode flag is lowered (S63-5) to cancel the shift mode. Next, stable mode display L

3c is turned off, the sort bin mode display LED 703b is turned on (S63-6), and the process returns. Note that if the determination in step 563-1 is not in the reservation mode, the guidance display in step 563-2 is not performed, and the processing from step S63-3 onward is executed. The shift tray mode subroutine in step 560-13 described above is the process shown in the flowchart of FIG. 64. This process lowers the stable mode flag and the sort bin mode flag (564-1.364-2), sets the shift tray mode flag (S64-3), sets the shift mode, and turns on the shift tray mode display LED 703C. is turned ON, the staple mode display LED 703a and the sort bin mode display LED 703b are turned OFF, and the shift tray mode is displayed (S64-5), and then the process returns. The staple end check subroutine in step 562-1 described above is the process shown in the flowchart of FIG. 65. That is, in this process, it is first determined whether the mode is stable mode (365-
1). If this judgment indicates that the mode is stable, it is judged whether or not the end of the staple has been reached (S65-
2). Detection of this end is determined by whether the stable abnormality l flag is set. Then, if the determination in step 565-2 is that the stable abnormality 1 flag is set,
Since the staple has reached its end, set the staple end flag (S65-3) and turn on the staple end display.

), then it is determined whether the reservation mode is set (S65-9). If it is determined in step 565-9 that the reservation mode is set, the program permits input of the reservation mode (S65-10) and returns; if the reservation mode is not set, the process returns directly. If it is determined in step 565-2 that the stability abnormality 1 flag is not set, the needle end has not been reached, so the process from step 565-7 onward is executed continuously, and the reservation mode is set in step S65-6. If it is determined that it is V, the processing from step 565-2 onwards is executed successively. (Processing using the 6, 5 copy processing key) In the mode set by the copy processing key, the 6th
The processing shown in the flowchart of FIG. 6 is executed. In the second process, it is first determined whether the finisher flag is set (S66-1), and if the finisher flag is set, it is determined whether or not the preheating mode is set.
), returns if not standing. Step 566-
If the determination in step 2 is that the preheating mode is selected, the process returns, and if it is not the preheating mode, it is further determined whether the preheating mode is being set (S663). If the setting is not in progress, it is determined whether the duplex back side copy mode is in progress (S66
-4). If it is a double-sided back side copy, return; if not, determine whether it is in double-sided front side copy mode (36
6-5), if it is in double-sided front side copy mode, it is further determined whether it is in a stopped state in the middle of copying 566-6), and if it is stopped, it returns, and if copying is continuing, further processing is performed. It is determined whether the duplex mode is set (S66-7). If the determination in step 566-5 is that the duplex front copy mode is not in step 566-6
The process proceeds to step 566-7 without performing the above process. If the determination in step 566-7 is duplex mode, it is further determined whether there is copy paper in the duplex tray 43 (366-8), and if there is copy paper, the process returns; if not, it is determined whether the mode is in interrupt mode. (S6
6-9). If it is determined in step 566-7 that the mode is not double-sided, the process directly proceeds to step 366-9 without performing step 566-8. If the determination in step 566-9 is the interrupt mode, the process returns, and if not the interrupt mode, it is further determined whether the copy processing key 701 is turned on. If the copy processing key 701 is in the OFF state, the process returns; if the copy processing key 701 is in the ON state, it is determined whether the stable mode display LED 701a is on (S661). The judgment in step 566-1) is O.
If N, execute the sort mode subroutine shown in the flowchart of FIG. 69 (described later) (366-14).

If N, execute the stack mode subroutine shown in the flowchart of FIG. 70 described later (S66-17).
) Return. If it is OFF, it is determined whether the stack mode display LED 701c is ON (S66-13). If the stack mode display LED 701C is ON as determined in step 566-13, execute the normal mode subroutine shown in the flowchart of FIG. 68 (described later) and return (S66-16); Execute the stable mode subroutine shown in the flowchart in Figure 67 (
S66-15) Return. The normal mode subroutine in step 566-16 described above is the process shown in the flowchart of FIG. 68. This process uses the sort mode flag,
Lower the stack mode flag and stable mode flag, respectively 568-1, 368-2, 368-3)
, further lowers the sort, stack, and stable mode flags 868-4), and finally sets the stable mode display LED 701a to indicate that these modes are not selected.
Turn off the sort mode display LED 70lb# and the stack mode display LED 701c (36
8-5). The sort mode subroutine in step 566-14 described above is the process shown in the flowchart of FIG. 69. In this process, it is first determined whether the mode is reservation mode (S69-1), and if it is the reservation mode, it is further determined whether the sort prohibition flag and the stack prohibition flag are set (S69-2). If step 5
If the sort prohibition flag and stack prohibition flag are set in the judgment in step 69-2, it means that the sort mode is not in effect.
Shift to the process shown in the flowchart in the figure, and step 3
68-1 and subsequent processes are executed. If the flag is not set, a guidance message is displayed saying "The job will be stabilized in 5 minutes after the JOB ends" (S69-3). Thereafter, the stable mode flag and stack mode flag are lowered (569-4, 569-5), the sort mode flag is set (S69-6), and the stable mode display LED 701a and stack mode display LED 7 are set.

(369-7) Return. Note that if the determination in step 569-1 is not the reservation mode, the process directly advances to step 569-4 and the subsequent processes are executed. The stable mode supruning in step 566-15 described above is a process as shown in the flowchart of FIG. 67. In this process, first, the stable needle end check subroutine shown in FIG. 65 is executed (567-1), and it is further determined whether there is any remaining paper in the sheet storage bin 57 (S67-2). If there are any remaining sheets, it is determined whether the reservation mode is selected (567-3), and if it is not the reservation mode, a guidance message "Please remove sheets from the bin" is displayed and the sort mode flag is lowered (S67-5). . When it is determined in step 567-2 that there are no remaining sheets in the sheet storage bin 57, or when it is determined that the reservation mode is in step 5673, the process directly proceeds to step 567-5. Then, in step 567-6, the stack mode flag is lowered, and in step 567-7, the staple mode flag is raised, and only the staple mode display LED 701a is turned on, and the process returns. The stack mode subroutine in step 566-17 described above is processing as shown in the flowchart of FIG. 70. In this process, first, it is determined whether the mode is reservation mode (S70-1). If it is in the reservation mode, execute the process from step 36B-1 of the flowchart in FIG.
-2.370-3), sets the stack mode flag (S70-4). And stack mode display LED7
Only 01C is lit (570-5), and it is further determined whether it is in the reservation mode (S70-6). If the determination in step 570-6 is the reservation mode,
A guidance message saying "Stapling will be performed 5 minutes after the end of the job" is displayed (S70-7) and the process returns. Further, if it is not the reservation mode in step 570-6, the process returns directly. Further, in connection with the above-described processing, since there are only 20 sheet storage bins 57 in this embodiment, consideration must be given to the number of copies, that is, the number of copies inputted using the numeric keypad. The processing for checking the number of copies, that is, checking the number of copies, is shown in FIGS. 71 and 72. FIG. 71 is a flowchart regarding processing in the staple mode. In this process, since there are only 20 sheet storage bins as described above, only up to 20 copies can be processed in the sort mode and staple mode. Therefore, first, it is necessary to determine whether the sort mode flag and staple mode flag are set.
), if it is not set, return; if it is, it is determined whether the copy number exceeds 20 (S71-2
). If the judgment in step 571-2 exceeds 20, turn on the display of "Copy number exceeded" 571-
3), and then returns with 20 copy 1 losses (371-4). If the judgment in step 571-2 does not exceed 20, the display of "Copy number exceeded" is turned off.
FF and return. On the other hand, in stack mode, as shown in the flowchart in Figure 72, first check whether the stack mode flag is set (572-1), and if it is not stack mode, return; if stack mode, the number of copies is set. It is determined whether the value is larger than 50 (S72-2). If the number of copies stored exceeds 50 as determined in step 572-2, the display of "Number of copies exceeded" is changed to 0NL.
(S72-4), set the copy number to 50 (S72-4)
). If it is determined in step 7 step 572-2 that the number of copies stored is less than 50, the display of "number of copies stored over" is turned off and the process returns. Note that this number 50 indicates the number of sheets that can be stacked. In the reservation mode, there is a limit to the number of originals that can be printed, so it is necessary to warn the user of the maximum number of originals. Therefore, in the case of the reservation mode, processing according to the flowchart of FIG. 73 is executed. In this process, first check whether the original (ORG) stapling mode flag is set.
73-1), if the flag is not set, next check whether the sort bin mode flag is set (S73
-2). If the sort bin mode flag is not set, return is made, and if it is set, it is further determined whether or not the reservation mode is set (S73-3>, if it is the reservation mode, the number of originals is 5).
If the number exceeds 0, the documents will be ejected to the blueprint tray.”
This guidance is displayed (S73-4), and if it is not the reservation mode, the process returns directly. Note that if the determination in step 573-1 is that the document stapling mode flag is set, step S
The processing from step 573-3 onwards is executed without performing the processing at step 73-2. Furthermore, since there is a limit of 50 copies even in the stable mode of copying, it is necessary to warn of the maximum number of copies of 50 copies in the reservation mode. Therefore, in this process, as shown in the flowchart of FIG. 74, it is necessary to check whether the stable mode flag is set (574-1),
If the flag is not set, it is determined whether the sort mode flag and stack mode flag are set (S74-
2). If the user is not standing, the process returns; if the user is standing, further judgment is made as to whether or not the reservation mode is set (S74-3>
. If it is in the reservation mode, a guidance message is displayed saying "If the number of sheets exceeds 50, the remaining sheets will be discharged to the blueprint tray" (S74-4), and if it is not in the reservation mode, the process returns directly. Note that if the determination in step 574-1 is that the staple mode flag is set, step 574
Step 574-3 and subsequent steps are executed without performing step 574-2. [7. Differences in flow due to differences in original and transfer paper modes] Figure 75 shows a schematic configuration of the copying machine 1 in Figure 1.

If the staple home position sensor 429 is not turned on in step 589-2, a stapler home request flag is set (S89-3), and if it is not turned on, it is immediately indicated that the jogger 63 is set at the specified jogging position. It is determined whether the jogger ready flag, which is a flag indicating the end of movement (“l” indicates the end of movement), is set (S894), Step 58
9-4 (7) If the jigger ready flag is set, set the jogger home return flag (S89-
5) If the jogger ready flag is not set, it is determined whether the drop roller home position sensor is turned on (589-6). The jogger home return flag is a flag that indicates the operation of returning the jogger 63 to the home position, and "1" indicates that the jogger 63 is being returned to the home position.The drop and roll home decision sensor is turned on based on the judgment of the steering knob 589-6. If not, the drop roller home return flag is set (S89-7), which is a flag to return the drop roller to the home position (“1” indicates that the return operation is in progress), and the drop roller home position sensor is activated. If it is ON, the bin home detection sensor 5
42 is turned on (S89-8
). If the bin home detection sensor 543 is not ON, a bin home request flag is set (S89-9), and if the bin home detection sensor 543 is ON, the first transfer paper entry detection sensor (transfer paper entry detection It is determined whether the detection signal of the sensor 1) 534 indicates that the transfer paper 37 has entered (S89-10). If the judgment in step 589-10 is that there is no paper, then the second transfer paper entry detection sensor (transfer paper entry detection sensor 1) 504
It is determined whether the detection signal indicates that the transfer paper 37 has entered (S89-1). If step 589-
10 or step 589-1), a copy transport jam flag is set (S89-1).
13) The CPU 573 indicates that the transfer paper 37 is jammed.
If there is no paper, the copy conveyance jam flag is lowered (S89-12), and the CPU 573 is notified that the transfer paper 37 is not jammed. The copy conveyance jam flag corresponds to a jam detected by the first or second transfer paper entry detection sensor 534, 504, and "1" indicates a jam, and "0" indicates no jam. Then, the first and second document entry detection sensors 5

” indicates no jam. If the judgment in step 589-17 is that there is no paper, a discharge jam flag corresponding to the jam detected by the discharge detection sensor 542 is set, with “1” indicating there is a jam and “0” indicating no jam. 589-18), and if there is paper, set the release jam flag (S 89-19).
), this time it is determined whether the detection signal of the tray paper ejection detection sensor 538 is in the state of being filled (S89-2).
0). If there is no paper, correspond to the jam detected by the tray paper discharge detection sensor 538, and lower the paper discharge jam flag which indicates a jam with '1'' and no jam with 0''S89-21); If there is paper, a paper discharge jam flag is set (S89-22), and it is further determined whether the door open sensor is ON (389-23). The door open sensor is set to O based on the judgment in step 589-23.
If it is in the FF state, it corresponds to the Fini 7 Sear 1) door ° oven, and lowers the door open flag that indicates the open state when "1" and the closed (normal) state when "0" 589
-24) If it is ON, set the door open flag (S89-25), and then judge whether the jogger home return flag is set (S89-26).
), if the jogger home return flag is not set,
Furthermore, it is determined whether the bin home request flag is set (589-27), and if it is not set, it is checked whether there is any remaining paper in the sheet storage bin 57 (S89).
-28), if there is no remaining paper in the tray, lower the tray remaining paper flag 589-29), if there is any remaining paper in the tray, set the tray remaining paper flag (S89-30), the staple end sensor is turned on. Determine whether it is (
S89-31). If the needle end sensor is in the OFF state, the needle end flag is lowered (S89-32); if it is in the ON state, the needle end flag is set (S89-33), and the switching wheel initial processing subroutine is executed (S89-32). 34)
Note that if the jogger home return flag is set as determined in step 389-26 and that the bin home request flag is set as determined in step 589-27, the process directly proceeds to step 589-34. . When the process of step 589-34 is completed, it is determined whether the bin home request flag is set (589-35), and if the bin home request flag is set, the flag is sent to the CPU 573 on the copying machine side (58).
9-39), if the bin home request flag is down, it is determined whether the jogger home return flag is up (S89-36). If the jogger home return flag is set, the CPU 573 on the copying machine 1 side
If the vehicle is getting off the vehicle, it is determined whether the wheel home request flag is set (S89-37). This wheel home request flag is a request flag for setting the switching wheel 477 to the controlled home position. Step 5
89-37, if the wheel home request flag is set, the flag is also sent to the CPU 573 on the copying machine 1 side 589-39), and if it is off, the initial request flag is lowered 589-38), copying machine 1 After sending the flag to the side CPU 573 (S89-39)
Return. (8,2 Jogger Drive Process) FIG. 90 is a flowchart showing the processing procedure of the jogger drive process. In this process, first, the count up of timer 2 is checked (S90-1), and if the count is not up, it is checked whether the jogging flag is set (S90-2). This jogging flag means that the jogger fence 472 is
1". If the jogging flag is not set, then check whether the jogger home return flag is set (390-3). If the jogger home return flag is not set, check the copying machine side. Decode the data sent from the CPU 573 5
90-4>, it is determined whether the mode reception data is 2 or 4 (S90-5). This mode reception data 2 is the code "001" shown in the above-mentioned FIG. 77, and the mode reception data 4 is the code "01)" shown in the above-mentioned FIG. It is. If it is determined in step 590-5 that the mode reception data is not 2 or 4, the process returns, and if it is determined that the mode reception data is 2 or 4, it is further checked whether the stapler home request flag is set (390-5). 6). If the stapler home request flag is set, the process returns; if it is not set, it is further determined whether the release detection sensor 542 is set (590-7). If it has fallen, the timer 1 is started (S90-8), the jogger ready flag is lowered 590-9), and the jogging flag is set (S90-10). Then, jogging data on the data table is selected based on the sheet size data (S90-1)), the selected jogging data is stored in the jogging memory (S90-12), and the process returns. Note that the process in step 590-1) shows a state in which the sheets are arranged. Note that the jogging memory indicates the position to which the jogger fence 472 is moved with the jogger home position as "0", and is used to control the movement of the jogger fence 472 in conjunction with the jogging counter. Further, if the release detection sensor 542 is not turned down as determined in step 590-7, the jogger ready flag is lowered (590-13), and jogging data on the data table is selected from the sheet size data (S90). -14). This process is in a standby state, and the jogger is evacuated from the seat. The jogging data selected in step 390-14 is stored in the jogging memory in step 590-15, and whether the data in the jogging memory and the value of the jogging counter indicating the position of the jogger fence 472 with the jogger home position as "0" are equal. If the two values are equal in the judgment at step 590-16, the jogger ready flag is set (590-17), and the value in the jogging memory is assigned to the jogging counter (S90-16).
18). Then, the jogger motor 463 is set to 0FFL (S90-1
9), lowering the jigger forward flag 590-2
0>, and also lowered the jogger reverse flag (39
0-21) Return. The jigger forward flag is a flag indicating movement of the jogger 63 in the direction in which sheets are aligned, such as paper alignment, and the jogger reverse flag is a flag indicating movement in the retreat direction from paper alignment. If the data in the jogging memory and the jogging counter value are not equal as determined in step 590-16, the jogging memory and jogging counter values are further compared (S90-22). Therefore, if the jogging memory value is greater than the jogging counter value, the jogger forward flag is set (S90-23).
), lower the jogger reverse flag (S90-24
) After adding the jogging counter in accordance with the jogger motor drive pulse (S90-25), return. On the other hand, if the value of the jogging counter is greater than or equal to the value of the jogging memory in step 590-22, the jogger forward flag is lowered (590-26), the jogger reverse flag is raised (S90-27), and the jogger motor drive pulse After decrementing the jogging counter in accordance with (S90-25), the process returns. Further, if the jogger home return flag is not set in the determination in step 590-3 described above, it is determined whether the home position sensor 471 is at the H level (S90-2).
9). If the level is L, set the jogger reverse flag (S90-30), turn off the jogger reverse flag (S90-31), and check whether the home position sensor 471 of the jogger 63 has risen (390).
-32). If it is determined in step 590-32 that the home position sensor 471 is not standing up, the process returns as is, and if it is determined that it is standing up, the jogger 63 is moved in the reverse direction by 3 pulses (590-33-FIG. 92). After stopping the motor 463 (S90-33) and lowering the jogger reverse flag (S90-35), the process returns. On the other hand, if the home position sensor 471 is at H level as determined in step 590-29, the jogger reverse flag is set at S90-36), the jogger forward flag is set at S90-37, and the jogger 63 returns to its home position. Check whether the position sensor 471 has fallen (S9038). If it has not fallen, it returns as is, and if it has fallen, it lowers the jogger forward flag 590-39) and stops the jogger motor 463 (S90-40). Thereafter, the jogger home return flag is lowered (590-41), the jogger ready flag is raised (S90-42>), the jogging counter is reset (S90-43), and the process returns. If the jogging flag is set, check whether timer 1 is counting up (590-44), return if not counting up, and stop timer 1 if counting up (S90-45). Then, it is checked whether the value of the jogging flag and the value of the jogging counter are equal (590-46), and if they are not equal, the processing from step 590-22 described above is executed. On the other hand, if the jogging memory value and the jogging counter value are equal, the jogger motor 463 is stopped (S9
0-47), lowering the jogger forward flag and jogger reverse flag 590-48, 590-49
), and further determines whether timer 2 has started (S90-50). If timer 2 has started, leave it as is. If not, start timer 2 (S9 (1-51), set the discharge OK flag (S90-52), and return. In addition, if timer 2 has already counted up as determined in step 590-1, the jogging flag is lowered (590-53), timer 1 and timer 2
After clearing (S90-54) step 590-13
Execute the following processing. Note that the above step 590-32 or step 59
At 0-38, the rise and fall of the jogger home position sensor 471 is checked for the following reasons. That is, as shown in FIG. 91, the jogger home position sensor filler 424 protruding from the jigger fence 472 advances and retreats, that is, the reverse side (in the direction of arrow 427R) with respect to the jogger home position sensor 471 consisting of a photointerrupter.
and move to the forward side (arrow 427 F), as shown in the timing chart of Fig. 92.
The home position of the jogger is defined as the falling edge of the home position sensor 471 (2 in the figure). This is because the amount of deviation in sensor characteristics occurs between the rise and fall of the sensor, so processing is performed so that the fall of the sensor output always becomes the home position regardless of the position Aqz or Bqz in FIG. 92. (8,3 Switching Wheel Initial Processing) Next, control of the switching wheel 415 will be explained. FIG. 93 is a flowchart showing the initial processing procedure of the switching wheel 477. In this process, first, it is determined whether the switching wheel home request flag is set (S93-1). If the flag is not set as determined in step 593-1, the process returns, and if it is, it is checked whether the switching wheel 477 is rotating in the forward direction (S
932). If it is not in the forward rotation, the switching wheel λ is rotated in the forward direction 477 (S93-3), the drive count <7 counter is reset (593-4), and the process returns. This driving pulse counter is a counter that indicates the position of the switching wheel 477, and "0" is the home position. It is used together with the drive nozzle memory when the switching wheel 477 is driven. The drive pulse memory indicates the position at which the switching wheel 477 is driven, and performs the same processing as a jogging counter and a jigging memory. On the other hand, if it is rotating in the forward direction, the drive pulse output is cut off (S9
3-5) Check whether the home position sensor 545 of the switching wheel 477 is up (5).
93-6). If it has not risen, check whether the drive pulse counter is OG or not, that is, whether it has been reset (593-7). If it has been reset, return as is, and if it has not been reset (593-7)). The drive pulse counter is incremented by one step and the process returns. Further, if the home position sensor 545 is turned on as determined in step 593-6, it is checked whether the drive pulse counter is set to O, that is, whether it has been reset (S93-9). If it has been reset, 1 is assigned to the driving pulse counter (S9
3-10) Return. If it has not been reset, the drive pulse counter is thicker than 150 (
593-1)), 15
If it is less than 0, assign 1 to the driving pulse counter (
S93-12) Return. If it is greater than 150, it is checked whether the drive pulse counter is less than 360 (S93-13). If it is less than 360, stop the drive pulse output and stop the rotation of the switching wheel 477 (S93-14), lower the wheel home request flag 593-15), reset the drive pulse counter (S93-16), and then return. do. On the other hand, if the value of the drive pulse counter is 360 or more as determined in step 593-13, the drive pulse output is stopped (S93-17), the drive pulse counter is reset (S93-18), and the switching is performed. A wheel rotation abnormality flag is set (S93-19) and the process moves to an abnormality processing routine. The switching wheel rotation abnormality flag is a flag that is "1" if the home position cannot be detected even if the switching wheel is driven for a certain number of pulses or more, and is normally "0". (8, 4 switching wheel drive processing) Switching wheel When the initial processing of 477 is completed, it becomes possible to drive the switching wheel 477. The processing at this time will be explained with reference to the flowchart of Fig. 94. In this processing, first, it is checked whether the initial request flag is set. (S94-1). If the flag is set, the home request flag of the switching wheel 477 is set (S94-2), and it is further determined whether the transfer paper conveyance flag is set (S94-3). If the flag is not set, the transfer Since paper 37 has not jammed, it is difficult to determine whether the document jam flag is set or not. 594-3
), if the original 69 is not jammed, the initial processing of the switching wheel shown in FIG. 93 is executed (394-5) and the process returns. Further, if the jam flag is set in the judgments in steps 594-3 and 594-4, it means that a jam has occurred in the transfer paper 37 or original document 69, and the process returns directly. If the initial request and est flags are off as determined in step 594-1, the transmission data from the CPU 573 side of the copying machine body is transferred to the CPU 651 of the finisher 1) side.
594-6), and determines whether the mode reception data is 0 (S94-7). If it is 0, return, and if not 0, it is further determined whether the mode reception data is 5 or less (394-8). This step 594
-8 returns if the judgment is 5 or less, and if it is 5 or less, sets the mode execution flag (S94-9), and judges whether the switching wheel 477 is rotating (S94-10).
). What is the mode execution flag?
The processing sent from 394-1 that requires a relatively long time is the flag that is set to "1" during the processing.If the switching wheel 477 is not rotating, the drive pulse counter data is loaded (394-1 )).Step 5941
), load the drive pulse counter data, then from the mode reception one word data and drive pulse counter data,
The data table of the drive pulse counter shown in FIG. 95 is searched. This data table switching wheel 477
Bano for transportation? The data is 1 of the stepping motor.
The pulse is set to correspond to the switching wheel 47701 degrees. Further, [a] to [d] in FIG. 95 correspond to the states (a) to d) of the switching wheel 477 shown in FIG. 96. The position of the switching wheel 477 in FIG.
Figure (b) shows the case where the original 69 is transported to the draft tray 59, Figure (c) shows the case where the copied transfer paper 37 is stored in the sheet storage bin 57, and Figure (d) shows the case where the copied paper 37 is stored in the sheet storage bin 57. The case where the transfer paper 37 is accommodated in the proof tray 59 is shown. When the search is completed in step 594-12, the data in the data table is stored in the drive pulse memory 594-13.
), the rotation of the switching wheel drive motor 487 consisting of a stepping motor is started according to the drive pulse memory (S94-14). After that, check whether the switching wheel 477 is rotating in the forward direction (594-15>), and if it is rotating in the forward direction, add 1 to the drive pulse counter and return (594-16).
If the switching wheel 477 is not rotating in the forward direction, check whether the switching wheel 477 is rotating in the reverse direction (394-17); if it is rotating in the reverse direction, subtract 1 from the drive pulse counter and return. If the switching wheel 477 is rotating as determined in step 594-10, check whether the value of the drive pulse counter and the value of the drive pulse memory are equal.
94-19), if they are not equal, the processes after step 594-15 are executed, and if they are equal, the rotation of the switching wheel 477 is stopped (S94-20), that is, the drive pulse output is turned off. Continue to lower the mode execution flag (594-21) and clear the drive pulse memory (594-21).
S94-22) Return. (8.5 Up-down check of sheet storage bin) Transfer paper 37 and original fi! The sheet storage bin 57 that stores sheets such as i69 needs to be moved up and down when receiving the sheets into the sheet storage bin 57, stapling the sheets, and discharging the sheets to the stack tray 67. . This is because the finisher 1) according to this embodiment does not process sheets by fixing the sheet storage bin 57, but moves the sheet storage bin 57 and processes various sheets, as can be seen from the explanation of the mechanical configuration described above. This is because it is intended to perform processing. Therefore, below,
Processing related to raising and lowering the sheet storage bin 57 will be explained. FIG. 97 is a flowchart showing a routine for raising and lowering the sheet storage bin 57 according to commands from the main body of the copying machine. In this process, first, when it is set to "1" on the copy Ill side, a check is made to see if the bin movement flag is set to match the bin position counter with the bin position data (597-1), and the bin movement flag is turned off. If it is standing, it will return as is, and if it is standing, the CPU 57 of the copying machine will
The CPU 651 of the finisher 1) receives data related to bin control transmitted from the finisher 3 side (397-2);
Note that the bin position counter is a counter that indicates the bin position currently being sent in the finisher 1). When the data is received, check whether the bin home request flag indicating that the seat storage bin 57 is to be moved to the home position is set (597-3). If it is, return; if it is, the bin is raised and Although the lowering flag is set, it is checked (S97-4).The state where the bin home request flag is set indicates that the sheet storage bin 57 is being returned to the home position. If it is determined in step 597-4 that the bin home request flag is set, the seat storage bin 5
597-5), and if the bottle is rising, set the bin position counter indicating the currently set finish + 1) since the bottle is rising. The bin position data indicating the bin position of finisher 1) that must be used is compared with the bin position data (S97-6). If it is determined in step 597-6 that the value of the bin position counter is smaller than the value of the bin position data, a bin rise flag is set and the seat storage bin 57
I (39
7-7) Return. Further, if the value of the bin position counter is equal to or greater than the value of the bin position data in the determination in steps 397 to 6, both the bin up flag and the bin down flag are lowered (S97-8.59).
7-9) Return. If the bin up flag is down as determined in step 597-5, it is checked whether the bin position counter is 1 (397-10). If the bin position counter is 1, execute steps 597-8 and 597-9 and return; if it is not 1, lower the bin up flag and set the bin down flag (397-1)) Return. Further, if the bin up/down flag is down as determined in step 397-4, check whether the value of the bin position counter is O (597-12), and if it is, set the bin up flag (S97-12). 13) Return, and if it is not 1, lower the bin lowering flag (S97-14) and return. (8, 6 Sheet storage bin lifting/lowering control) When the above check routine is completed, the seat storage bin 57 is actually
This means that the robot will move up and down. The processing procedure in this case is shown in the flowchart of FIG. In this process, first, while the stapler operation including the movement of the stapler 65 is being executed, the stapling execution flag, which becomes "1", is set (598-1). If not, it is determined whether the bin home request flag is set (398-2). If the bin home request flag is off as determined in step 39B-2, it is determined whether the discharge OK flag is on (39B-3). This paper ejection flag becomes "1" when the copy 1) 1 and the sheet conveyed from the original transport unit are ejected through the release detection sensor 542, and becomes "o" when the sheet storage bin 57 moves etc. If the discharge OK flag is down in step 39B-3, the process returns; if it is up, the bin movement flag is up, but it is determined (598-4).
Return if you are down, stapler 65 if you are standing.
Returns stapler to home position Home position request flag ('1 while returning to home position)
”) is standing (39B-5
), if it is standing, return, and if it is broken, return the drop roller to the home position. Determine whether the drop roller home return flag (which becomes "1" while returning to the home position) is set (398- 6). If it is standing, return; if it is falling, it is further determined whether the bottle rise flag is set (398-7). If the determination in step 598-7 is that the bin up flag is off. This time, it is determined whether the bin lowering flag is lowered (398-8). If the bin lowering flag is down, stop the movement of the seat storage bin 57. 598-9>
, lower the discharge OK flag and return (39B-1
0). Also, if the bin lowering flag is set in step 598-8, lower the bin by one bin (398-1))
, decrements the bin position counter by 1 (39B-12), lowers the discharge OK flag (39B-13), and returns. On the other hand, if the bin lift flag is set in step 39B-7, the bin is raised by 1 bin (398-14), the bin position counter is set by 1 (398-15), and the paper is discharged.
Set the flag (898-16) and return. Note that if the bin home request flag is set in step 59B-2, it is difficult to determine whether the stapler home request flag is set in step 59B-17.
), if it is standing, it returns as is, and if it is getting off, it is determined whether the drop-off home return flag is set (S98-18). Based on this judgment, if the drop roller home return flag is set, the return is made, and if it is lowered, the bin motor 418 is turned on to the lowering side to lower the sheet storage bin 57 (39B-19). Next, the seat storage bin 57 is lowered and it is determined whether or not the bin home position sensor 543 is ON (398-20). If the bin home position sensor 543 is OFF in this determination, return is made, and if it is ON, the bin motor is 418 to stop the movement of the sheet storage bin 57 (39B-21), reset the bin position counter 39B-22), lower the bin home request flag (S98-23), and return. (8, 7 Stapler Movement Process) The stapling operation is executed as the sheet storage bin 57 moves, but in order to execute the stapling operation, it is necessary to advance the stapler 65 from the home position to the stapling position. This requires moving the stapler. FIG. 99 is a flowchart showing a procedure for moving the stapler. In this process, first, it is determined whether the stapler home request flag is set (S99).
-1). If the stapler home request flag is down in this judgment, the staple error 1 flag indicating the presence or absence of staples in the stapler 65 (61" at the staple end of the stapler,
Determine the status (normally "0") (S99-2>. If the staple abnormality 1 flag is set in this judgment, return as is, and if it is off, then the staple abnormality 2 flag indicating an abnormality in the staple motor (not shown) is determined. Determine whether the flag is set. If the staple error 2 flag is set in this judgment, return is made, and if it is down, there is no abnormality in the stapler 65, so this time the stapler home position is set to 0 and the stapler 65 position is indicated. It is determined whether the position counter is 0, that is, the stapler is located at the home position (S99-4). If the value of the counter is not 0 in this determination, the value of the stapler position counter is 50. -5)
, if it is 50, return the stapler to the home position (599-6), which lowers the stapler reverse flag ("l" when moving to the reverse side; normally "0"), and then moves the stapler 65 from the home position to the stapling position. Lower the stapler forward flag to be projected (“1” when moving to the forward side, “0°” normally) (S9
9-7) Return. If the value of the stapler position counter is not 50 in step 599-5, it is determined whether the stapler reverse flag and stapler forward flag are set (S99-8). It makes a quick turn, and if it is getting off, it lowers the stapler home request flag (S99-9) and returns. Further, if the stapler position counter is 0 in the judgment at step 599-4, the processing from step 599-9 onwards is executed. On the other hand, if the stapler home request flag is set in the determination at step 399-1, it is further determined whether the stapler home position sensor 429 is ON (399-10); if it is OFF in this determination, , sets the stapler reverse flag, lowers the stapler forward flag (399-14), and returns. If the above judgment is ON, lower the stapler home request flag 599-1)), lower the stapler reverse flag and stapler forward flag (S99-12), reset the stapler position counter (599-13), and then return. do. (8, 8 Stapling Process) The stapling process performed as the stapler moves is performed according to the processing procedure as shown in FIG. 100. In this process, first, it is determined whether a jogger ready flag indicating that the jogger 63 has been set at a designated jogging position is set (3100-1). In this judgment, if the jogger ready flag is down, the process returns as is, and if it is up, the staple abnormality 1 flag and staple abnormality 2 flag are checked (5100-
2.5100-3). If the staple abnormality l flag or the staple abnormality 2 flag is set, the process advances to the abnormality processing routine, and if both flags are off, it is determined whether the sheet storage bin 57 is being moved (5100~
4) If it is determined that the sheet storage bin 57 is moving, the process returns; if the sheet storage bin 57 is not moving, it is further determined whether the discharge OK flag is set (5100-5). In this judgment, if the discharge OK flag is set, return is made, and if it is off, the state of the drop roller return flag is judged (S
100 6) If the falling turn flag is set in this judgment, return is made, and if the falling turn flag is set, the state of the stapler home request flag is judged (S100-7).
. If the stapler home request flag is up in this judgment, the process returns; if it is down, the state of the staple flag is determined (3100-8).
This flag is used to execute the stapling operation at "l". If the stapling flag is set in this judgment, the process returns; if it is lowered, the stapling flag becomes "1" while the stapling operation including the movement of the stapler 65 is being executed. If the stapling execution flag is off in this determination, it means that stapling is not being executed, so the stapler forward flag is set and the stapler 65 is moved to the stapling position (S100-9). 10), performs stapling on the sheet (5100-1)), sets a stapling execution flag (8100-12), and
2 jogs (S100-13) and returns. On the other hand, if it is determined in step 5100-9 that stapling is being executed, it is further determined whether stapling has been completed (step 5100-14), and if it has not been completed, step 51
The processes from 00-10 onwards are executed, and if completed, the stapler reverse flag is set and the stapler 65 is evacuated from the stable position (S100-15). Then jog the jogger fence 472 (5100-1

17) Return. (8, 9 Sheet Dropping Process) When stapling is performed on sheets, sheet dropping processing is performed according to the set mode. 10th
FIG. 1 is a flowchart showing the processing procedure of sheet dropping processing. In this sheet dropping process, first, the state of the dropping roller home return flag is determined (5101-
1). If the fall home return flag is down in this judgment, the stable abnormality 1 flag (5101-2)
, the states of the staple abnormality 2 flag (3101-3) and the staple flag (S101-4) are determined. and step 3101-2, 5IOI-3 or 5IO
If any of the relevant flags in I-4 are an obstruction, the process returns, and if all the relevant flags are set, it is determined whether or not the seat is stored in the seat storage bin 57 (SI
Ol-5). If the sheet is present in this judgment, it is further judged whether the sheet storage bin 57 is being moved (5101-6
). If moving is in progress, return; if not, determine the state of the stapling execution flag (SIOI
-7), if the stapling execution flag is on in this judgment, the process returns; if it is off, it is judged whether the mode reception data is 6 (SIOI-8). If this judgment indicates that the mode reception data is 6, a dropping process is executed to drop the stapled sheet onto the quick-touch tray 67 (S101-9), and the process returns. On the other hand, if the drop roller home return flag is set as determined in step 5IOI-1, a drop roller reverse flag indicating that the drop roller moves in the direction of retraction from the sheet storage bin 57 side is set (SIOI-1
)), lower the drop roller forward flag indicating that the drop roller moves to the sheet storage bin 57 side, that is, to the drop operation side. 5lot-12) Determine whether the drop roller standby home position sensor 438 is ON. (8101-13). If the drop roller standby home position sensor 438 is OFF as determined in step 5IOI-13, the process returns as is, and if it is ON, the drop roller reverse flag is lowered (5101-14), and the home position sensor 438 is "O".
” (SIOI-15). Then, the drop roller home return flag (drop roller return operation in progress) that returns the drop rollers 431, 433 to the home position is reset (SIOI-15). Return at step 5IOI-16) to unload the sheet storage bin 57.
When it is determined that there is no sheet, the drop roller drive motor 441 is turned to 0FFL (S103-4), and the 5-second timer is stopped and cleared (3103-5). Then, the drop roller forward flag and the drop roller reverse flag are lowered (5103-6, 5103-7), and the drop roller home return flag and the mode end flag are set (S103-8. 8103-9). Next, the one second timer is stopped and cleared (5103-10), and the state of the home position sensor 438 while waiting for the drop roller is determined (Slot-10). If this judgment indicates that the return roller standby home position sensor 438 is OFF, step 51
01-1) and subsequent processes are executed, and if it is ON, the process from step 5IOI-1) is jumped to step 3101-13, and the process of step 5101-14 is executed. FIG. 102 is a flowchart showing the processing procedure during execution of dropping stapled sheets. In this process, first, the state of the drop roller forward flag is determined (5102-1), and if this flag is off, then the state of the drop roller reverse flag is determined (5102-1).
S102-2). If the drop roller reverse flag is an obstacle in this judgment, the drop roller drive motor 441 is checked (S101-3). If the drop roller drive motor 441 is in the OFF state, the drop roller drive motor 441 is turned ON ( S102-4) and returns after resetting the loop counter (S102-5). The loop counter is a counter that counts the number of protrusions and retractions of the drop roller, and performs this count six times per sheet, and only if the sheet still does not reach the sheet release sensor is a jam. On the other hand, if the drop roller drive motor 441 is in the ON state, the drop roller forward flag is set (S102-6), and the drop roller reverse flag is lowered (5102-7), and the drop roller counter becomes 120 pulses or more. (
S102-9). With this judgment, the drop counter is 12.
If the pulse is 0 or more, the drop roller forward flag is lowered 5102-10), and the state of the sheet release sensor 545 is determined (5102-1)). If the sheet release sensor 545 is OFF in this judgment, then Unable to determine whether the 1 second timer has started 5102-1

), the 5-second timer and the 1-second timer are stopped and cleared (3103-15, 3103-16), and a sheet ejection jam flag is set (S103-17), and the process moves to the abnormality processing routine. Note that the sheet release jam flag is a flag that becomes "1" when the stapled sheet does not fall onto the stack tray 67. Further, when it is determined that the sheet release sensor is ON in step 5102-1), the process moves to the flowchart of FIG. 103, and it is determined whether the 5-second timer has started (3103-1) If not, a 5-second timer is started (3103-2) to return, and if it has been started, it is checked whether the sheet discharge sensor has fallen (3103-3). If it has fallen, the process from step 5103-4 described above is executed, and if it has not fallen, it is determined whether the 5-second timer is counting up (S103).
-1)). In this judgment, if the 5-second timer has not counted up, the process returns, and if it has counted up, the process from step 5IO3-12 described above is executed. Furthermore, if it is determined in steps 8102-2 that the drop roller reverse flag is set, it is determined whether the sheet discharge sensor 545 is turned down (
S103-21). With this judgment, the sheet release sensor 545
If the sheet release sensor 545 has fallen, the process from step 5103-4 onwards is executed, and if the sheet discharge sensor 545 has not fallen, the process from step 5102-16 onwards is executed. Note that if it is determined in step 5102-1 that the drop roller forward flag is set, step S
Processes from 102-6 onwards are executed.

[9. Original Processing Control] The control of post-processing of the transfer paper 37 and the original 69 has been described so far. Therefore, document processing control for feeding and processing the document 69 according to a plurality of input mode settings will now be described in detail. Incidentally, the timing of cent, paper feeding, ejection, etc. of the original 69 is based on the timing chart shown in FIG. 104. (9,1 Initial processing) Initial processing includes: ■Door open check of document reversing unit, ■Optional connection check for document conveyance unit, ■Bin home request processing in multi-stage unit, ■Conveyance section (pressure plate) of document conveyance unit. There is a lift-up check and an initial jam check. (2) Door open check of document reversing unit 52 First, a check is made regarding the opening of the door in the document feeder, that is, in this embodiment, the document transport system 9. FIG. 105 is a flowchart showing the door oven check processing procedure. In this process, the state of the document reversing unit connection flag (“1” if connected, “0” if not connected) indicating whether or not the document reversing unit 52 is connected to the document transport unit 51 is determined ( S105-1). In this judgment, if the document reversing unit connection flag is not set, the process returns as is, and if it is, the document reversing unit 51
determines whether the door is open, and if it is open, lowers the document reversal jam flag 5105-3), sets the document reverse unit door oven flag (S105-4),
Furthermore, the above-mentioned document reversal jam flag and document reversal unit door oven flag are set to the CPU on the copying machine main body side.
573 as serial data and return. Further, if the document reversing unit door is closed as determined in step 5105-2, the document reversing unit door oven flag is lowered (S105-6) and this flag is set to
Send to PtJ573 and return. Furthermore, what is the above-mentioned document reversing unit, 7-toji, and Yamflag? First document entry detection sensor 3 of document reversing unit 52
70, a flag for the second entry detection sensor 368;
The document reversing unit door open flag is a flag that is set to "1" when the door of the document reversing unit is open and "0" when it is closed. Since the document stack tray 353, multi-stage unit 50, etc. are optionally connected in this embodiment, a check is performed to determine whether any optional devices are connected to the document transport unit 51.This processing procedure is shown in the flowchart of Fig. 106. In this process, the boat mode and RAM are first cleared, flags and counters are reset, and initial setting subroutines are executed to perform initial settings (S106-
1). Next, it is determined whether the document reversing unit 52 is connected (S106-2). This determination is made using the input port of the gate array 605 on the side of the document transport unit 51 and checking the level of the input port. In this case, if connected, the level is "L", and if not, the level is "H". Therefore, step 5106-2
If it is determined that the document reversing unit 52 is connected, a document reversing unit connection flag is set (510
6-3), if it is not connected, lower the document reversing unit connection flag 3106-4), and further determine whether the multi-stage unit 50 is connected (
S106-5). The connection of this multi-stage unit 50 is also performed in the same manner as the connection of the original reversing unit 52. Based on the judgment in step 5106-5, the multi-stage unit 50
If connected, set the multi-stage unit connection flag (3
106-6), if not connected, lowers the multi-stage unit connection flag (S106-7) and transmits the reversing unit connection flag and the multi-stage unit connection flag to the CPU 573 side of the copying machine body as serial data (S106-7).
SiO2-8). Note that the multi-stage unit connection flag indicates the connection state of the multi-stage unit 50 to the original transport unit 51, and the multi-stage unit 50 is connected to the original transport unit 51.
“1” if connected to 1, “0” if not connected
”. Needless to say, in this embodiment, the multi-stage A
DF 49 has multi-stage unit 50 and original transport unit 5X
It is pointed. When the process of step 5106-8 is completed, check whether there is a transmission error (S106-9), and if there is no error, return; if there is an error, execute the transmission error processing routine (S106-10). Return. ■ Bin home request processing in multi-stage unit This process is performed by the document bin 201 for feeding the document 69.
This is to return the camera to its home position and determine its initial position. This processing procedure is shown in the flowchart of FIG. In this process, first, the state of the bin home request flag is determined (5107-1).
01 receives this and sets the bin home request flag as “
1", that is, sets the bin home request flag and moves the document bin 201 to the home position.
When the document bin 201 moves to the permanent position, the flag is lowered and sent to the CPU 573 of the copying machine main body. If the bin home request flag is set in step 5107-1, the bottom plate home position sensor 25
1 is determined (S107-2). In this judgment, if the bottom plate home position sensor 251 is OFF, the bottom plate raising motor 241 is reversely rotated, the bottom plate 21) is lowered (S107-3), and the process returns, and the bottom plate home position sensor 251 is ON, that is, the bottom plate 21) is If it has returned to the home position, turn off the bottom plate lift motor 241.
to stop the bottom plate 21) at the home position (
S107-4). Next, the leading edge detection sensor 243 determines whether there is any remaining paper (5107-5), and if there is any remaining paper, a paper jam flag is set in the flowchart of FIG. 108 (3108-15), and step 8108 described below
-1 and subsequent routines are executed, and if there is no remaining paper, the registration detection sensor 245 determines whether there is any remaining paper (S10?-6).If there is any remaining paper in this judgment, the flowchart shown in FIG. Step 3108-1
Execute the routine from step 5, and if there is no remaining paper, check the status of the bin home sensor 222 (5107-7), and if the pin home sensor 222 is ON, stop the reverse rotation of the wheel motor 231 and replace the original. The bin 20I is made to stand by at the home position (3107-8), and the bin switching solenoid 240 is set to 0FFL (S10?-
9) Lower the paper jam flag of the document transport unit 51 (S107-10). This paper jam flag is a jam flag for the leading edge detection sensor 243 and the registration detection sensor 245, and is normally “
0" and "1" when there is a jam. When the paper jam flag is lowered in step 5107-10, the bin counter (DF pin counter) of the document bin 201 and the bin counter memory (DF upper pin counter memory)
(S1071)). The DF pin counter is connected to each document bin 20 of the above-mentioned five-stage multi-stage unit 50.
This is a counter that indicates the position of 1, and the count has the following meaning. 0: All five bins are located at the lower bin home position. 1: When zipping the first or topmost bin and moving that bin. 2: When processing a job in the second bin and moving that bin. 3: Job processing for the third bin and movement processing for that bin. 4: Job processing for the fourth bin and movement processing for that bin. 5: Job processing for the fifth or bottom bin, and processing for moving that bin. Further, the DF upper pin counter memory is used for DF pin counter memory during interrupt processing and during reservation mode processing. When the process of step 5107-1) is completed, the bin raise flag is further set (5107-12), the bin home request flag is set S107-13), and the initial jam check subroutine is executed (S107).
-14) Return. On the other hand, in step 5107-7, the pin home sensor 222
When it is determined that the wheel motor 2 is OFF, the wheel motor 2
31 rotation (S107-15). If the wheel motor 231 is rotating in the reverse direction as determined in step 5107-15, the process returns; if it is rotating in the forward direction, the state of the wheel standby home position sensor 253 is checked (S107-15). S107-16), if the wheel standby home position sensor 253 is OFF in the check, the wheel motor 231 is rotated forward to move the Geneva wheel 207 to the wheel standby home position (S107-1
7) Return, and if it is ON, stop the forward rotation of the wheel motor 231 and stop the Geneva wheel 207 at the wheel standby home position (S107-18);
After that, turn on the bin switching solenoid (S107-1
9) Rotate the wheel motor 231 in the reverse direction to lower the document bin 201 and return. (2) Restore check and initial jam check of the conveyance section of the document conveyance unit FIG. 108 is a flowchart showing the procedure for lift-up check and initial jam check of the conveyance section of the document conveyance unit. In this check routine, first, it is determined whether the conveyance section of the document conveyance unit (hereinafter also referred to as DF) is lifted up, in other words, whether the pressure plate 288 is opened (510B-1), and if it is not lifted up, the DF Lowering the lift-up flag 51
08-2) Check whether there is any remaining paper using the paper discharge sensors 321 and 322 (8108-3). If the document 69 remains at the sensor position, the reversal jam flag (
Set “0” normally, “1” when jammed) (3108-4)
, if no document 69 remains, the first and second entry detection sensors 370, 36B determine whether or not the document 69 remains (310B-5). If the pressure plate 28 is lifted up as determined in step 3108-1, the reverse jam flag is lowered 3.
108-108-6), ADF lift up flag (
If the pressure plate of the DF is lifted, set it to "1"; if the pressure plate is closed, set it to "0") (5108-7), and then set the document transport motor 323 and reversing solenoid 316 to zero.
Clear FFL, size data and counters (S
108-8) Proceed to step 3108-5. If the document 69 remains in the first or second document entry sensor 370 or 368 as determined in step 3108-5, a document reversal jam flag is set (5108-9); The presence or absence of paper ejection is determined according to 321 and 322. Original discharge sensor 321, 3
22 is ON, the document 69 remains in the paper ejection section, so the document reversal jam flag is set (SiO2-1))
, if it is OFF, the original stack tray 382
Determine whether manuscript 69 exists in (310B-1
2) If there is a document 69, it is detected by the star/cutter tray paper end sensor 376, and a remaining paper check flag is set which becomes "1" if there is any remaining paper in the document stack tray 382, and "0" if there is not. (310B
-13) If not, each flag is directly transmitted to the CPU 573 on the copying machine main body side (S108-14) and the process returns. Also, step 5 of the flowchart in FIG.
If the initial jam check routine has proceeded from step 107-5 or step 5107-6,
After setting the paper jam flag (3108-15), the process from step 3108-1 onwards is executed. (9. Movement of 2 Original Bins) The selection and movement of 5 original document bins 201 is executed in accordance with the zip determined by the copying machine main body. The processes related to the selection and movement of the document bin 201 include (1) multi-stage unit bin number data input process, (2) bin movement process based on data received from the copying machine main body, (2) bin raising process, and (2) bin lowering process. Each case will be explained in detail below. (2) Bin number data input process for multi-stage unit FIG. 109 is a flowchart showing the processing procedure for inputting bin number data for the multi-stage unit. In this process, first, the state of the multistage unit connection flag is determined in order to confirm the connection state of the multistage unit 5o.
109-1), if the multi-stage unit connection flag is down, output dummy data and return as is; if it is up, decode the data sent from the CPU 573 of the copier main body (8109-2), When the data is decoded, it is checked whether the copy mode received data is 0 (S109-3). If it is 0, return as is, and if it is not 0, check whether the copy mode received data is 5 or less.
7 risuru (3109-4). If it is larger than 5, return, and if it is less than 5, set the document bin 201 that matches the mode reception data to the paper feed home position (
SiO2-5) Return. Note that step 81 above
The number 5 in the copy mode received data, which is the criterion for determining 09-4, comes from the fact that the multi-stage unit 50 has five stages. Therefore, it goes without saying that the results will be different if the number of stages of the multi-stage ADF 49 is different. (2) Bin movement processing based on data received from the copying machine main body 1) Figure 0 is a flowchart showing the processing procedure for bin movement based on data received from the copying machine main body. In this process, first check the status of the bin set end flag (
Sll-0-1). Vince. The end flag is a flag indicating whether or not the document bin 201 has been set from the standby home position to the paper feed home position, and is 1" if set, and O if not set. If the bin set end flag is set at step 31) 0-1, the document bin 201 is set at the paper feeding home position, so the process returns as is. Store in request bin memory (31) 0-2). Then, check the status of the bin home request flag.
o-3) If the bin home request flag is set, the vehicle returns as is, and if the vehicle is alighted, the state of the wheel standby home position sensor 257 is checked (S1
)0'-4). Note that the bin home request flag above refers to the bin home request flag on the copier main body side that is “1”.
”, this flag is received by the DF side and sets the bin home request flag on the DF side to “1” to execute the return of the document bin 201 to the home position.
7 is not located at the standby home position, lower the bin home request flag (Silo-5).
The program returns and determines whether the value of the DF top pin counter and the value of the request bin memory are equal (SILO-6). If the two are equal in this judgment, execute a subroutine to move the document bin 201 to the paper feed position, that is, the paper feed home position (SIIO-10), and return; if they are not equal, the value of the DF upper pin counter will be Determine whether it is larger than the value of the request bin memory (Silo
-7), and if the value of the DF upper pin counter is less than or equal to the value of the request bin memory, the DF bin raising processing subroutine described later is executed to raise the document bin 201 (Sil
o-8) If the value of the DF upper pin counter is larger than the value of the request bin memory, execute the DF bin lowering processing subroutine described later to lower the document bin 201 and T(S
1) 0-9) Return after executing the subroutine of steps 5ilo-10. (2) Bottle Lifting Process The content of the bin lifting process subroutine in step 5ilo-8 is as shown in the flowchart shown in FIG. 1)1. In this process, first, vftm is performed to determine whether the value of the pin counter on the DF and the number of bins stored in the request bin memory are equal (Sill-1). If the two are equal, set the standby set end flag and return (Sl
1l-2). This standby set end flag is the CPU 5 on the copying machine main body side.
The document bin 201 has been moved by the number of bins sent from 73 and has been designated as the standby home position sensor 257.
This is a flag that becomes "1" when set. On the other hand, if it is determined in step 51) 1) that the value of the DF upper pin counter is not equal to the number of bins stored in the request bin memory, the wheel motor 231 is rotated forward to raise the document bin 201 (Sill -3), check if timer 1.2 has started 5ill-
4) If timers 1 and 2 have not started, start both timers (Sill-5) and return. Also, if timers 1 and 2 have started, check whether timer 1 has counted up (5ill-6); if it has not counted up, return; if it has counted up, check the state of the standby home position sensor 257. Check (Sill-7). If the standby home position sensor 257 is ON in this check, the forward rotation of the wheel motor 231 is stopped and stopped at the standby home position (S1) 1-8), and the DF pin counter is incremented by 1.51) 1- 9) Stop and clear timers 1 and 2 (Sill-10) and return. On the other hand, if the standby home position sensor 257 is in the OFF state in the check at step 5ill-7, a check is made to see if the timer 2 is counting up. Then, if the count-a-knob is not up, it returns as is, and if the count-up is up, the wheel motor 2
31 to stop the movement of the document bin 201 (S1) 1-12). Next, timers 1 and 2 are stopped and cleared (5ill-13), and then the bin abnormality flag is set (Sill-14) and the process proceeds to the abnormality processing routine. The bin abnormality flag is "1" if there is an abnormality in the moving operation of the document bin 201, and is normally "0". (2) Bin Lowering Process The contents of the subroutine of the DF bin lowering process in step 5ilo-9 are as shown in the flowchart shown in FIG. 1)2. In this process, first the bin switching solenoid 24

(9, 3 Original Bin Paper Feeding Position Set) In order to process the original stored in the original bin 201 according to the input mode, the original bin 201 containing the original to be processed in that mode must be set. It is necessary to move the document to the document feeding position and set it. The processing procedure of this process is shown in the flowcharts of FIG. 1) 3 and FIG. 1) 4. 1) In the processing procedure shown in Figure 3, first, it is determined whether the standby set end flag is set (S1) 3-1
). Based on this judgment, if the standby set end flag is down, it returns as is, and if it is up, the bin switching solenoid 2

If it is counting amplified, stop the reverse rotation of the wheel motor 231. 51) 3-8) Stop and clear the timer 3 (Sl 13-9) I. Set the bin abnormality flag (51) 3-10 ) Return. On the other hand, if the timer 3 has not counted up in the check of step 31) 3-7, the state of the paper feed home position sensor 259 is checked (Sl 13-1))
If the paper feed home position sensor 259 is OFF in this check, the process returns; if it is ON, the reverse rotation of the wheel motor 231 is stopped and the document bin 201 is stopped at the paper feed home position (S1) 3-12 ). Next, the timer 3 is stopped and cleared 51) 3-13), the standby set end flag is lowered 51) 3-14), the bin set end flag is set (S1) 3-15), and then the process returns. 1) In the processing procedure shown in Figure 4, first check to see if there is a document jam, and then start processing (S1) 4

Send to U573 (Sl 14-10) and return. (9,4 Feed-in Process) The feed-in process is a process in which a document feed signal is input from the CPU 573 side of the copying machine main body and the conveyance of the document 69 to the document conveyance unit 51 side is started. Specifically, the process is executed according to the flowchart shown in FIG. 1). In this process, first, the state of the paper jam flag is checked (S1) 5-1), and if the paper jam flag is set, the document 69 is jammed in the multi-tier unit 50, so the paper jam flag is flagged. is transmitted to the CPU 573 side of the main body of the copying machine (51)5-2), and the paper feed jam check subroutine shown in the flowchart of FIG. 1)6 described later is executed (S1)5-3), and then the process returns. On the other hand, if the paper jam flag is down, it means that no jam has occurred, so the state of the document center flag is checked (81)5'-4). The document set flag is a flag indicating whether or not there is a document 69 on the document bin 201, and is "1" if there is a document, and "0" if there is not. If the original cent flag is down at the check in step 51) 5-4, the process returns; if it is up, the CPU 5 of the copying machine

If the document feed flag is down at step 31) 5-6, the process returns, and if it is up, the state of the document duplex flag is checked (S1) 5-6). If this double-sided document flag is set, it is a double-sided document, so execute the subroutine for double-sided document feeding. Execute (S1) 5-9). After executing any of the subroutines, the state of the paper jam flag is checked (S1) 5-10). If the paper jam flag is off during this check, set the copy start flag (
S1) 5-1)), the copy start flag and document size data were sent to the CPU 573 side of the copying machine main body (
S1) Return after 5-12). On the other hand, if the paper jam flag is set in step 31)5-10, step 51)5-2 and step 51)
Execute the process 5-3 and return. (9, 5 Paper Feed Jam Check Process) This process is a process for retracting the document bin 201 in order to improve the removal of the jammed paper when a jam occurs during the feed-in of the document 69. 1) The specific processing procedure is shown in the flowchart of FIG. 6. In this process, first, the lift-up of the document transport unit 51 is checked (31) 6-1), and if the lift-up is lifted, the ADF lift amplifier flag is set (Sl 1

(9, 6 Document discharge processing) The document 69 that has been exposed for copying is discharged to any of the document discharge tray 285, document stack tray 382, draft tray 59, and sheet storage bin 57, and is subjected to predetermined processing. is executed. This processing includes (1) document discharge processing I, (2) document discharge processing (2), (2) initial processing, and (2) switching motor drive processing. Note that the two flowcharts shown in Figure 1) 7 and Figure 1) 8, which will be described later, are for determining the destination (discharge method) of the original 69 based on code data from the copying machine. The paper ejection process I is a process for selecting the four types of ejection methods shown in FIGS. 127 and 129, and the document ejection process (2) is a process for selecting the three switching positions I shown in FIG. 22. This will be explained in detail below. (1) Original discharge processing I This processing procedure is specifically shown in the flowchart of FIG. 1)7. In this process, first check whether the paper is being ejected51)
7-1) If the paper is not being ejected, CPO5 of the copying machine
The data from the 73 side is decoded (5II7-2), and if the document discharge process is in progress, it is checked whether the document discharge flag is set (S1)7-3). If the document discharge flag is down in this step Sl 17-3, we return, and if it is up, we check whether the copy mode reception data is between 6 and 9 (S1) 7-4)
. The received data in step 51) 7-4 is for checking whether the document stack tray is in the ejection mode. Step S1) If it is determined in 7-4 that the copy mode reception data is between 6 and 9, it is further checked whether the document reversing unit connection flag is set.
1) 7-5) If the user is standing, that is, if the document reversing unit 52 is connected, it is checked whether the door of the document reversing unit 52 is open (51) 7-6). When it is confirmed that the door is closed, step S1)7
-7 executes the document ejection processing subroutine, and further checks whether the copy mode received data is 6 or 9 (51)7-8), and if it is neither 6 nor 9, the original 6
If it is 6 or 9, execute the subroutine to eject 9 to the original stack tray 382 (S1) 7-10). Return. Also, when the copy mode reception data is not between 6 and 9 in step 51) 7-4, when the document reversing unit connection flag is lowered in step S1) 7-5, and when the door of the document reversing unit 52 is open. If so, the subroutine of step 51) 7-1) for document discharge processing is executed, and the document 69 is discharged onto the document discharge tray 285 on the DF (S1) 7-12), and then the process returns. Note that step 51) 7-7 and step S1) 7-
The subroutine 1) is a process based on the flowcharts shown in FIGS. 61 to 65 described above, and includes step 51).
The subroutine 7-9 is a process based on the flowchart in FIG. 105, and the subroutine 7-10 is a process based on the flowchart in FIG. 106, step S1)? The subroutine -12 is a process based on the flowchart in FIG. 108. These processes have already been described in detail in the above-mentioned (2nd and 3rd document reversing section). ■Document discharge processing■ This processing procedure is shown in the flowchart of FIG. 1)8. In this process, it is first checked whether the copy mode received data is between 6 and 9 (51) 81). If it is not between 6 and 9, the process returns, and if it is between 6 and 9, the document stack unit Check whether the connection flag is set (31) 8-2). If this document reversing unit connection flag is set, that is, if it is confirmed that the document reversing unit 52 is connected, it is checked whether the copy mode reception data are 6 and 7 (31) B- 3). Therefore, if the copy mode reception data is 6 and 7, the subroutine for switching motor drive processing is executed (S1) B=4) and the process returns. This subroutine sets the switching motor back flag, stores 20 in the step angle memory, and sets the switching motor back flag.

-5) Return. ■ Switching of the initial processing document reversing unit 351 is performed by a stamping motor, and the switching home position sensor 378 is set to ONL, and the position when the switch is set to the home position is set as the home position. (1) No movement (Fig. 22) (2) Bank 20 steps on the side (Fig. 23) (3)
Switching processing is performed in three patterns of 20 steps (FIG. 24) on the forward side. The document transfer unit 351 of the document reversing unit 52 can be driven in forward and reverse directions. (1) Forward rotation: Linear speed equivalent to that of the DF conveyance belt 53, etc. (2) Reverse rotation: Sheet discharge on the copy Ill side There are two patterns of linear speed and linear speed equivalent to the sheet discharge linear speed of finisher 1). In this case, forward rotation is the direction of rotation in which the document is transported from the paper discharge section side of the DF to the document stack tray 382 side, and reverse rotation is the direction in which the document is transported from the document stack tray 382 side to the reversing unit switching mechanism and further to the finisher 1) side. This is the direction of rotation. This initial process is a process in which the switching mechanism is set at the home position and the document transport section 351 is not moved. This processing procedure is shown in the flowchart of FIG. 1). In this process, first, check whether the reversing unit switching home request flag is set.51)9-
1) If the user is not standing, return; if the user is standing, check whether the switching home position sensor 378 is turned on (51) 9-2). If ON, lower the switching motor forward flag and bank flag Sl 19-3), reset the step angle counter (51) 9-4) lower the reversing unit switching home request flag (31) 9. Return after -53. On the other hand, if the switching home position sensor 378 is OFF in step 51)9-2, it is checked whether either the switching motor forward flag or the bank flag is set (51)9-6). If either flag is down, reset the step angle counter 51) 9-7), set the switching motor forward flag (S1) 9-8) and set the switching (stepping) motor 3.

31)9-9). Next, the step angle counter is incremented by 1 (51) 9-10), and when the count value of the step angle counter becomes greater than 50 (51) 9-1)), the switching motor forward flag is lowered (51) 9-12). Reset the step angle counter (S1) 9-13) Set the switching motor back flag (51) 9-14) Return. Further, when it is determined in step 51) 9-6 that either the switching motor forward flag or the back flag is set, the state of the switching motor back flag is checked ('31) 9-15). If the switching motor back flag is down, the process from step 51) 9-8 onward is executed, and if it is up, the switching stepping motor 3

If it is 6 or more (S1) 9-18), the switching motor back flag is lowered 51) 9-19), the step angle counter is reset (S1) 9-20), and then the process moves to the abnormality processing routine. (2) Switching Motor Driving Process The switching motor of the document reversing unit 351, that is, the switching stepping motor 377 is driven according to the processing procedure shown in the flowchart of FIG. 120. In this process, first, it is checked whether the step angle counter has been reset (5120-1), and if it has not been reset, a reversing unit switching home request flag is set (S I 202) and the process returns. If it has been reset, check whether the reversing unit switching home request flag is set (S120-3).
. If the reversing unit switching home request flag is set, return is made, and if the reversing unit switching home request flag is set, it is checked whether the switching motor forward flag and back flag are set (5120-4). If these flags are set, it is further checked whether the switching motor back flag is set (S120-5), and if it is set, the switching stepping motor 377 is driven one step back (31206), and the switching motor back flag is set. If so, the switching stepping motor 377 was driven one step forward (S120).

)), the switching stepping motor 377 is set to 0FF (S12
0-12) and return. Note that step 5120
If the switching motor forward flag and the bank flag are off at step -4, and if the step angle memory and the step angle counter are not equal at step 5120-9, the process returns directly. (9, 7 Original stack unit processing) This process involves transporting the original 69 to the original stacking tray 382 and moving the original 69 on the original stacking tray 382 to the roller 381.
This is the process of arranging them. Specifically, this is performed according to the processing procedure shown in the flowcharts of FIGS. 121 and 122. In the process shown in FIG. 121, first, the original stack tray 3

Next, the call solenoid 386 is de-energized and a jam check timer, timer 3, is started (81
21-14) Return. On the other hand, in step 3121-3, the first entry detection sensor 3
When it is determined that timer 70 is OFF, it is checked whether or not timer 1 has started (5121-15), and if it has not started, it is started (5121-16) and the process returns. If it has started, wait until timer 1 counts up (5121-17), and if it counts up, stop timer 1.2 and clear it. 5121-18
), sets the document discharge jam flag (S121-19),
A flag is sent to the CPU 573 side of the copying machine (51
21-12) Move to the jam processing routine. In addition, in the process shown in FIG.
1) If it is ON, check the count-up of the 0 and 3 second timer that counts the processing time for moving the original 69, as shown in the timing chart of Fig. 135 (
S 122-2). Then, when the count is amplified, the 0.3 second timer is stopped and cleared (S122-3), and the document loading roller drive solenoid 383 is turned off (S122-4), and the process returns. In contrast, the document loading roller drive solenoid 383 is turned off.
If F, check the state of the timer 3 and send 512

If there is no count amplifier, check whether the original ejection sensor 379 of the original stack unit has risen as shown in FIG. 135 (3122-7). If it does, stop timer 3 and return after clearing (5122-8). If it is not raised, it is checked whether the document ejection sensor 379 of the stack tray section 677 is lowered (S122-9). If it has not fallen down, it returns, and if it has fallen down, it starts a 0.2 second timer which is a delay timer until the ejected document 69 falls onto the document stack tray 382, as shown in FIG. S122-10),
Add 1 to the ejected original document number counter (S122-1))

and return. It goes without saying that the document shifting roller 381 may be configured to perform 0N10FF multiple times for one ejected document. (9,8 Re-feeding process) This process is to feed the original 69 to the finisher 1), and the sheet processing after the original 69 is fed to the finisher 1) is similar to that for the transfer paper 37. It is. Specifically, the paper refeeding process is performed according to the processing procedure shown in the flowchart of FIG. 123. In this process, first, the state of the transport jam flag is checked in order to know the transport state of the document 69 (5123-1).
If the conveyance jam flag is set, the process moves to the abnormality handling routine, and if the document reversing unit 52 is off, it checks whether the door of the document reversing unit 52 is open (5123-2), and if it is open, the process moves to the abnormality handling routine. , if it is closed, check whether the document reversal jam flag is set (S
123-3). If the original reversal jisem flag is set,
The process moves to the abnormality processing routine, and if the document feeding start flag is off, the state of the document feeding start flag is checked (S123-4). If the document feeding start flag is not set, that is, document feeding has not started, the process returns; if the document feeding start flag is set, in other words, if document feeding has already started, The state of the document feeding flag is checked (S123-5). If the document feeding flag is set, it means that document 69 is being fed at that point, so check whether it is time to repeat the feeding.5123-6) At the same time, it is checked whether there is a document 69 on the document stack tray 382 (S123-7). If there is no original document 69 on the original stack tray 382, the document feeding flag is lowered and the process returns. If there is a document 69 on the document stack tray 382, the paper refeed clutch located coaxially rearward of the separation roller 390 shown in FIG. 21 is turned ONL (S123-

Figures (a) to d) are timing charts showing the flow of the document 69 and the operation timings of the turn roller, conveyance heald, first and second paper ejection sensors, and reversing solenoids due to differences in conveyance patterns. a) or d)
The patterns correspond to each of the explanatory diagrams specifically showing the flow of a document in FIGS. 129(a) to 129(d). First, the configuration of each part such as the turn roller will be explained with reference to FIG. 128, which is a diagram of the main part configuration of FIG. 2 mentioned above. Although this partially overlaps with the explanation regarding FIG. 2, in the finisher 1) example of the contact glass 17, a driven roller 305 for tensioning and driving the conveyor belt 53 is disposed on the left side of the figure, and further to the left side of the finisher 1). Turn roller 31
5 is located. First and second driven rollers 324 and 326 are in rolling contact with this turn roller 315, and furthermore, the finisher 1) of both rollers 324 and 326
First and second paper ejection sensors 32 are installed on the transport path in the example.
1,322 are provided. Further, the conveyance path 3 formed on the outer periphery of the turn roller 315
1) in the clockwise direction along the first to third direction switching claws 3.
18a, 318b, and 318c are provided. These direction switching pawls 318a, 318b, and 318c are oscillated by a reversing solenoid 316 to switch the direction in which the document 69 is conveyed. Four conveyance directions are set for the document 69 as described below, and these directions are switched by the first and second paper ejection sensors 321 and 32.
In step 2, the process is executed based on the rise during document conveyance, that is, the arrival of the document 69, and the fall, that is, the timing when the document 69 leaves the sensor position. FIG. 127(a) shows a document 69 placed on the document stack tray 38.
2 shows the timing of conveyance. In this case, the turn roller 315 and the conveyor belt 53 start forward rotation (F) at the same timing. On the other hand, the reversing solenoid 316 is in the OFF state, and the first direction switching pawl 318a maintains the state indicated by the dashed line. The first paper discharge sensor 321 detects the document 69, and when the document 69 passes through the detection position of the first paper discharge sensor 321 and the output of the sensor falls, at this timing the turn roller 315 and the conveyor belt 53 are turned off at the same time. That is, the original 69 is transported from the transport belt 53 to the original stack tray 382 via the turn roller 315 as shown by the arrow in FIG. 129+8). Note that the time indicated by the symbol A in the figure is the time for the original 69 to pass through the first discharge detection sensor 321, and it naturally varies depending on the size of the original 69. 127) shows the timing when the document 69 is conveyed to the document stack tray 382 after being reversed. In this case, the turn roller 315 and the conveyor belt 53
starts forward rotation (F) at the same timing, and at the same time, the reversing solenoid 316 is turned on. As a result, the first and second
and third direction switching claws 318a, 318b, 318c
becomes a solid line. Then, the first paper ejection detection sensor 321 is turned ON by conveying the document 69, and after a delay of time B, the second paper ejection detection sensor 322 is turned ON, and then the first paper ejection detection sensor 321 is turned OFF. , furthermore, when the second paper discharge detection sensor 322 turns OFF and falls down, the document 6

Then, the first to third direction switching claws 318a. 318b and 318c are in the state shown by the dashed-dotted line, and in this state, when the delay time C, which takes into account the delay time of the operation of the reversing solenoid 316, has elapsed, the turn roller 315 rotates in the reverse direction (R). As the turn roller 315 rotates in the reverse direction, the original 69 passes above the second direction switching claw 318b and is ejected to the original stack tray 382 side of the original reversing unit 52 in an inverted state. As a result, the document 69 flows as shown by the arrow in FIG. 129(b). In addition, time B
is a timing difference due to a difference in the placement positions of the first and second paper discharge detection sensors 321 and 322 on the conveyance path. FIG. 127fcl shows the timing when the original 69 is inverted and conveyed onto the contact glass 17. In this case, the turn roller 315 and the conveyor belt 53 start forward rotation (F) at the same timing, and at the same time, the reversing solenoid 316 is turned on. As a result, the first, second and third direction switching claws 318
a, 318b, and 318c are solid lines. and,
The first paper ejection detection sensor 321 is turned ON by the conveyance of the original 69, and after a delay of time B, the second paper ejection detection sensor 322 is turned ON.
When turned ON, the reversing solenoid 316 is turned OFF when the second discharge detection sensor 322 rises. When the reversing solenoid 316 is turned OFF, the third direction switching pawl 318c is brought into a state shown by a chain line. Furthermore, the conveyor belt 53 starts to rotate in reverse at approximately the same timing as the fall of the first discharge detection sensor 321, and when the leading edge of the document 69 reaches the conveyor belt 53, the document 69 is moved by the conveyor heald 53 to the contact glass 17. It is pulled in to the side and conveyed onto the contact glass 17. When the document 69 is completely conveyed onto the contact glass 17, the turn roller 315 and the conveyance belt 53 stop. As a result, the document 69 flows as shown by the arrow in FIG. 129 (C1). Note that the time period indicates the timing until the document 69 reversed by the turn roller 315 reaches the transport heald 53. (d) shows the timing when the document 69 is discharged onto the document output tray 285 of the document transport unit 10. In this case, the turn roller 315 and the transport belt 53 start forward rotation (F) at the same timing. death,
At the same time, the reversing solenoid 316 is turned on. As a result, the first, second and third direction switching claws 318a, 318
b and 318c are solid lines. Then, the first paper ejection detection sensor 321 is turned on as the original 69 is conveyed, and the second paper ejection detection sensor 322 is turned on after time B, and the original 69 passes through the second paper ejection detection sensor 322. When the time E elapses after the lever sensor 322 falls and the paper passes through the discharge roller 319, the turn roller 315 and the conveyance belt 53 stop, and the document 69 is transferred to the document conveyance unit 51.
The document is discharged onto the document discharge tray 285. As a result, the document 69 flows as shown by the arrow in FIG. 129(d).
