2.2 Sorter Section 2.2.1 Paper Feeding / Discharging Section As shown in FIGS. 3 to 11, the paper feeding / discharging section 41 includes a pick-up lever 67 and a pick-up lever 67 that are substantially V-shaped in a side view. A pin 71 that engages with the engaging groove 69 formed at one end, and a pickup arm 75 having a pickup roller 73 at the other end, and a pick-up roller drive shaft 99, which will be described later, provided at substantially the center of the pickup arm 75. A retracting lever 79 that engages through an engaging groove 78, a pickup solenoid 81 that swings and drives the pick-up lever 67 with respect to the support shaft 68, a pair of sheet feeding / discharging rollers 83 provided at one end of the sheet conveying path 135, 84, a bin stopper 85 provided below the paper feeding / discharging roller 84, a bin stopper solenoid 87 for driving the bin stopper 85, and a sheet A first switching claw 89 that switches between the document transport path 45 and the first transport path 47 following the transport path 135, a support pin 91 that swingably supports a retract lever 79, and a retract that drives the swing lever 91. And a solenoid 93.

2.2.2 Pickup Roller Mechanism The pickup roller mechanism is provided with a pickup roller driving gear 95 and a pickup roller driving pulley 97 at both ends, as shown in the plan view of the main part of FIG. A pickup roller driving shaft 99, which is rotatably supported by bearings 113 and 115 between the front side plate 109 and the rear side plate 111 of 33, and a pickup arm 75, is rotatably supported at one end. It basically comprises a rotating shaft 107 having a driven pulley 101 and a pickup roller driving idler 105, and applies the driving force transmitted by a pickup roller driving gear 95 between the pickup roller driving pulley 97 and the driven pulley 101. The pickup roller 73 axially attached to the rotating shaft 107 via the belt 103 provided It is adapted to dynamic.

2.2.3 Pickup Roller Evacuation Mechanism As shown in FIGS. 3 and 9, the pickup roller 73 enters the space between the bins 37 when picking up a document, and thus interferes with the movement of the bins. Become. Therefore, it is necessary to retract the pickup roller 73 from between the bins 37 and retract it when the bin 37 is moved or when the transfer paper or the document is fed (at the time of pickup). Therefore, the retreat lever 79, the retreat solenoid 93, etc. described above are provided.

In this mechanism, when the retracting solenoid 93 is turned on, the retracting lever 79 rotates counterclockwise (direction CCW in FIG. 9) about the support pin 91 from the state shown in FIG. Similarly, move 75 counterclockwise. By this movement, the pin 71 erected at one end of the pickup arm 75 moves along the engagement groove 69 of the pickup lever 67, and the pickup arm 75 engages with the engagement groove 78 of the retract lever 79. It is defined as a triangle formed between the drive shaft 99, the pin 71 and the support pin 91, and is retracted to a position as shown in FIG. By this retracting operation, the pickup roller 73 is retracted from between the bins 37. During this retracting operation, the pickup roller driving gear 95 provided on the pickup roller driving shaft 99 separates from the pickup roller driving idler 105.

On the other hand, when the pickup roller 73 is returned from this retracted state, if the retract solenoid 93 is turned off, the retract spring 117 causes the retract lever 79 to move clockwise around the support pin 91 (arrow CW direction in FIG. 8). This causes the pickup arm 75 to be guided clockwise by the engagement groove 69, whereby the pickup roller 73 returns to the original position between the bins 37, and at the same time, the pickup roller driving gear 95 moves the pickup roller driving idler. It engages with 105 to enable rotation of the pickup roller 73 (Fig. 8). In this retreating and returning operation, the bearing 113 is in the opening 119 of the front side plate 109 of the sorter shown in FIG. 10 (reference numeral SB in FIG. 10) to be guided (the bearing 115 similarly moves to the opening (not shown) of the rear side plate 111). Further, the pin 71 moves the thickened portion of the opening 119 in the vertical direction (reference numeral UD in FIG. 10). The shape of the feeding position FF of the opening 119 is set so that the meshing state between the pickup roller driving gear 95 and the pick-up roller driving idler 105 can be maintained by vertically controlling the bearing 113. is there.

2.2.4 Pickup Roller Contact / Separation Mechanism When feeding from the bin 37, the pickup roller 73 is brought into contact with the document or transfer paper stacked on the bin 37, and the pickup roller 73 is driven to drive the bin. Pull out from 37. Therefore, the pickup roller 73 must be brought into contact with or separated from the original document / transfer sheet on the bin 37 as required.

In this mechanism, the pickup arm 75 is swung with respect to the support shaft 68 by the pickup lever 67 so that the pickup arm 75 is brought into contact with and separated from the spindle 68. That is, when the pickup solenoid 81 is turned on, the pickup lever 67 rotates in the clockwise direction in FIG. 11 (the arrow RCW direction in FIG. 11), and the pin 71 of the pickup lever 75 is picked up in the counterclockwise direction (indicated by the arrow in FIG. 11) with respect to the pickup roller drive shaft 99. Rotate in the ACCW direction). As a result, the pickup roller 73 is biased toward the bin 37 side (RP in the figure), and presses a sheet such as a document or a transfer sheet on the bin 37. When the pickup roller 73 rotates in the pressurized state as described above, the sheet can be discharged from the bin 37.

When the pickup roller 73 is separated from the seat, when the pickup solenoid 87 is turned off, the elastic biasing force of the return spring 121 causes the pickup lever 67 to rotate counterclockwise with respect to the support shaft 68. As a result, the pickup arm 75 rotates clockwise with respect to the pickup roller driving shaft 99, and the pickup roller 73 separates from the sheet (RD in the figure).

2.2.5 Drive Mechanism of Pickup Roller The pickup roller 73 obtains a driving force from the rotation of the paper feed roller 83 above the paper feed rollers 83 and 84. That is, when the upper paper feed roller 83 rotates, the pickup roller drive idler 105 that comes into contact with the paper feed roller 83 rotates, and the pickup roller drive gear 95 that meshes with the pick-up roller drive idler 105 rotates and this rotation drive is performed. The force causes the pickup roller 73 to rotate in the direction of the arrow PU in FIG. 11 via the pickup roller driving shaft 99, the pickup roller driving pulley 97, the belt 103, the pickup roller driven pulley 101, and the rotating shaft 107, so that the sheet 37 Can be discharged from above.

2.2.6 Bin Stopper Drive Mechanism The bin stopper 85 is for opening and closing the bin fence 123. The bin fence 123 allows the leading end portion of the sheet placed on the bin 37 to move to the bin 37. It is for regulation at the outlet. The bin fence 123 is laid down when the sheet is taken out from the bin 37, and is controlled to stand up at other times. The bin stopper 85 is swingably supported with respect to a swing fulcrum 125, is connected at one end to a bin solenoid 87 via a return spring 127, has a rising portion 131 at the other end, and further has a rising portion 131 from the rising portion 131 at its tip. An abutting portion 133 that is bent at a substantially right angle is formed. The bin fence 123 is swingably supported by a support shaft 129 while being elastically biased in the standing direction.

With such a configuration, when the bin solenoid 87 is turned on, the bin stopper 85 rotates in the counterclockwise direction (arrow BSCCW direction) with respect to the swing fulcrum 125 in FIG. By this rotation, the contact portion 133 advances inward from the rear side plate 111. On the other hand, the bin fence 123 part of the ascending bin 37 contacts the advanced contact part 133, but since the bin 37 itself further ascends, it moves in the clockwise direction (arrow BFCW direction) as shown in FIG. It will fall and not interfere with the paper feeding operation.

Further, when the bin solenoid 87 is turned off, the bin stopper 85 rotates clockwise with respect to the swing fulcrum 125, and the abutting portion 133 of the bin stopper 85 retracts from the rear side plate 111 and restricts the bin fence 123. To cancel. As a result, the bin fence 123 stands up, regulates the position of the sheet on the bin 37, and prevents the sheet from falling.

2.2.7 Bin Driving Mechanism There is one sheet conveying path 135 which is provided with the paper feeding / discharging rollers 83 and 84, and to which the original conveying path 45 and the first transfer sheet conveying path 47 are connected, and Since it is fixed, a driving mechanism for the bin 37 that moves the bin 37 to feed the sheet from the bin 37 and ejects the sheet into the bin 37 as described above is required.

As shown in FIGS. 14 and 15, this mechanism is provided with a helical wheel 137, a bin holder 139, a guide groove 141 formed in the side plates 109 and 111 of the sorter 33, and a bin drive loosely fitted in the guide groove 141. Basically, it is composed of a shaft 143 and a drive motor for a helical wheel 137 (not shown). The helical wheel 137 is a known one having a spiral groove 145 formed on the outer periphery thereof, and the end portion 147 of the bin drive shaft 143 can be movably engaged as shown in FIG.

In such a mechanism, when the helical wheel 137 is rotated by the drive motor, the end portion 147 of the bin drive shaft 143 of the bin 37 corresponding to the spiral groove 145 formed in the helical wheel 137 causes the spiral groove 145 to rotate. Is guided to raise and lower the bin drive shaft 143. In response to this, the bottle 37 also moves up and down. Since the bin drive shaft 143 is also loosely fitted in the guide grooves 141 of the side plates 109 and 111, the ascending / descending locus is defined by the guide grooves 141. As can be seen from FIGS. 14 and 16, the guide groove 141 is set such that the stop position is different between when the paper is discharged to the bin 37 and when the paper is fed from the bin 37. That is, the paper discharge position is the position of PIN in FIG. 14, and while the helical wheel 137 makes one rotation from the paper discharge position PIN, the position rises to the standby position PWAIT via the paper supply position POUT. Further, the bin holder 139 causes the drive shaft 143 to be gripped in the spiral groove 145 of the helical wheel 137 by lifting the bin group from below as shown in FIG. 16 when the bin 37 is raised. Is becoming

2.2.8 Feeding / Discharging Operation by Pickup Roller When a sheet is fed / discharged by the pickup roller mechanism, the pickup roller retracting mechanism, the pickup roller driving mechanism, the bin driving mechanism and the like configured as described above. The operation of will be described below.

The sorter 33 discharges the transfer paper in the sort / stack mode, and in the multi-stage ADF mode, each bin 37 serves as a manuscript set table to supply and discharge the manuscript. That is a major feature. In this sorter 33, when the transfer paper and the original are discharged, the transfer paper is discharged to the bin 37 by the paper supply / discharge rollers 83 and 84 as in the conventional apparatus. On the other hand, at the time of feeding the original, the original is picked up from the bin 37 by the pickup unit including the pick-up roller 73 and the pickup arm 75 for feeding, and the original is fed. This has been partially described, but will be described in detail below.

2.2.8.1 Operation During Discharge of Transfer Paper FIG. 4 is a front view of the main parts showing the operation during discharge of the transfer paper. In the figure, the pick-up roller 73 is in the retracted state by the retracting lever 79, and the bin fence 123 is standing up and standing by because the bin stopper solenoid 87 is OFF. The transfer sheet PR enters the sheet conveying path 135 from the first transfer sheet conveying path 47 along the switching claw 89 switched to the lower side, and the image forming surface is turned upward by the sheet feeding / discharging rollers 83 and 84. The paper is discharged from the paper mouth 136 onto the bin 37. The position of the bin 37 at this time is the position of the PIN described above.

2.2.8.2 Operation during Document Ejection FIG. 5 is a front view of the essential parts showing the operation during document ejection. This state is the same as that in FIG. 4 except that the direction of the switching claw 89 is different. The original document OL is conveyed along the original document conveyance path 45, along the switching claw 89, from the sheet conveyance path 135 through the sheet supply / discharge rollers 83, 84, and from the sheet supply / discharge port 136 to the bin 37 with the copy surface facing upward. Discharged on top.

In this state of paper feeding, as described above, the retracting solenoid 93 is turned off and the retracting lever is rotated clockwise to set the pickup roller 73 between the bins 37. At this time, the bin stopper solenoid 87 is turned on, the bin stopper 85 is rotated, and the contact portion 133 is lowered. As a result, the bin fence 123 is tilted as shown in the figure. Further, the first switching claw 89 is at the upper position and is switched to the document feeding path 45 side.

In this state, when the motor (not shown) rotates, the upper paper feeding / discharging roller 83 rotates, and this rotation causes the pickup roller 73 to rotate in the direction of the arrow in the figure as described above (solid line position in FIG. 6). On the other hand, the lower paper feeding / discharging roller 84 remains stopped, and has a function of a separation roller at the time of feeding a document. The original OL is set in the bin 37 with the copy surface facing downward, and when the pick-up solenoid 81 is turned ON with the original OL set, the pickup lever 67 moves clockwise with the support shaft 68 as the fulcrum as described above. When the pickup arm 75 rotates, the pickup arm 75 rotates counterclockwise around the pick-up roller drive shaft 99 as a fulcrum, and the pickup roller 73 comes into pressure contact with the uppermost document OL. At this time, since the pickup roller 73 is rotating in the direction of the arrow shown in the drawing as described above, the uppermost document OL is pulled out in the direction of the paper feeding / discharging rollers 83, 84, and the action of the lower paper feeding / discharging roller 84. Then, the sheets are separated one by one, and are conveyed to the document conveyance path 45 via the paper feed / discharge port 136, the sheet conveyance path 135, and the switching claw 89.

The lower paper feeding / discharging roller 84 is a roller having a built-in one-way clutch. When the original document OL and the transfer paper PR are discharged to the bin 37, the lower paper feeding / discharging roller 84 is rotated along with the upper paper feeding / discharging roller 83. It rotates in the clockwise direction and is locked when the original OL is picked up from the bin 37, so that it functions as the separating roller.

It comprises a solenoid 169 and a sheet feeding / discharging roller 173 provided adjacent to a sheet feeding / discharging port 171 of a conveying path 165 continuing to the RHD 9 side of the reversing guide plate 43.

With this configuration, the original OL placed face down on the bin 37 is inverted to make the copy surface upward, and is correctly fed to the RDH 9. The inversion operation will be described below.

2.2.9.2 Reversing Operation of Documents Feeded from Bin Bin The original document OL picked up from the bin 37 by the pick-up roller 73 enters the document feeding path 45 and is fed upward as described above. Be done. At this time, the switching pawl driving solenoid 169 and the reversing solenoid 161 are both OFF, and the reversing solenoid 161 is returned to the initial position by the return spring 162. As a result, each part of the document reversing unit 44 is in the state shown in the two-dot chain line in FIG. 17 and in the state shown in FIG. When the contact / separation roller 151 is retracted from the reversing guide plate 43 by rotating in the direction, the second switching pawl 157 is switched downward, the reversing conveyance path 155 is opened, and the switching pawl drive solenoid 169 is turned off. As a result, the third switching claw 163 rotates counterclockwise with respect to the support shaft 177, and the fourth switching claw 167 rotates clockwise with respect to the support shaft 179. The carrying path 45 and the reversing conveying path 155 are in communication with each other, and the reversing guide plate 43 and the supply / discharge port 171 are in communication with each other by the fourth switching claw 167. In this state, when the document OL is conveyed upward, it is deflected by the third switching claw 163 from the document conveyance path 45 to the reverse conveyance path 155, and the conveyance roller 86 guides the front end of the document OL to the reverse guide. In the drawing of the plate 43, it is conveyed in the left direction (arrow OLLF in FIG. 18). Then, when the rear end of the document OL passes through the second switching claw 157, the reversing solenoid 161 is turned on. As a result, the contact / separation roller drive arm 153 and the switching claw drive lever 159 rotate clockwise about the support shafts 174 and 175 as a fulcrum, and as shown in FIG. While pressing, the second switching claw 157 switches upward to close the reversing conveyance path 155 and open the conveyance path 165 on the reversing guide plate 43. At this time, since the reverse return roller 149 is constantly rotating in the arrow R RCW direction, the original force OL starts to advance to the right due to the conveying force thereof.

When the leading edge of the original document OL has passed the conveyance roller 86, the reversing solenoid 161 is turned off to prepare for the next original document OL to enter. On the other hand, the reversed original OL is conveyed rightward on the reverse guide plate 43 by the conveying roller 86 rotating in the direction of the arrow even if the driving force of the reverse returning roller 149 is lost, and is conveyed from the sorter 33 side to the RDH 9 side. It is sent from the discharge port 171 to the RDH 9 side by the paper feeding / discharging roller 173 that rotates in the transport direction.

2.2.9.3 Discharging Operation of Original Documents Ejected from Original Document Supply Device to Bin The original document OL discharged from the RDH 9 to the sorter 33 side is copied from the RDH 9 side to the sorter 33 side. It is introduced into the transport path 165 by the paper feed / discharge rollers 173 that rotate in the transport direction. At this time, as can be seen from FIG. 20, the switching claw solenoid 169 is turned on, the fourth switching claw 167 counterclockwise with the support shaft 179 as a fulcrum, and the third switching claw 163 supports the support shaft 177. The fourth switching claw 167 communicates the conveyance path 165 and the document conveyance path 45, and the third switching claw 163 opens the document conveyance path 45 by rotating clockwise as a fulcrum. As a result, the document OL is transported downward along the document transport path 45 and discharged from the sheet transport path 135 onto the bin 37 in the state of FIG. At this time, the originals OL are ejected with the copy side facing up, so when the originals are stacked in the bin 37, the originals before copying and the originals already copied can be seen at a glance.

2.3 Mechanism of Staple Unit 2.3.1 Staple Unit Mechanism The staple unit 35 moves in parallel along the staple unit 53 and the bottom plate 187 of the staple tray 55, as shown in FIGS. 21 and 22.

The stopper 63 is in the solid line position in FIG. 21 when the stopper solenoid 195 is OFF, prohibits the ejection of the transfer paper PR from the staple tray 55, and when it is ON, retracts to the two-dot chain line position to transfer the transfer paper PR. It enables the discharge of bundles. Incidentally, when both the closing roller solenoid 201 and the stopper solenoid 195 are turned off, the return springs 207 and 209 are set to return to the initial position.

2.3.2 Operation of Staple Section In the staple section configured as described above, the transfer paper PR sent from the sorter section 33 to the staple 35 side via the third transport path 51 is further After passing through the inlet guide plate 191, the sheet is discharged and stacked in the staple tray 55 by the pair of discharge rollers 197. At this time, the stopper solenoid 201 is OFF, and the pulling roller arm 205 causes the pulling roller 199 to rotate in the direction of the arrow in the standby state as shown by the solid line. The stopper solenoid 195 is also OFF, and the stopper 63 is also in the stop position shown by the solid line as described above.

In this state, when the trailing edge of the transfer sheet PR passes through the pair of discharge rollers 197, the shifting roller solenoid 201 is turned on, and the trailing edge of the transfer sheet PR is abutted against the stopper 63 by the shifting roller 199. .. At the same time, the jogger fence is driven to align the transfer paper PR on the bottom plate 187. The details of this paper alignment operation will be described later.

The discharge rollers 203 are formed in a half-moon shape as described above, and when the transfer paper PR is discharged onto the staple tray 55, the cut-out planar portion 211 becomes parallel to the bottom plate 187 so that the bottom plate 187 is formed. Since it is retracted from the surface, it does not hinder the discharge of the transfer paper PR to the staple tray 55.

In this manner, the bundle of transfer sheets PR having a plurality of laminated sheets is stapled at the upper left corner by a known stapler to form one bundle. When the stapling is completed and the bundle is formed in this way, the stopper solenoid 195 is turned on and the stopper 63 is rotated to the two-dot chain line position in FIGS. At the same time, a paper feed clutch (not shown) is turned on, the discharge roller 203 is rotated, and the shift roller Solenoid 201 is also turned on so that the shift roller 199 presses the transfer paper PR against the discharge roller 203. As a result, as shown in FIG. 22, the bundle of transfer papers is conveyed to the discharge guide plate 59 side along the bottom plate 187, and is discharged to the paper discharge stocker 57 along the discharge guide plate 59.

7. 7.1 Controls and operations 7.1 Controls performed by the copier body include key input check, stapler check, maximum sort count check when entering number, maximum stack when entering number in mode setting by operator. Number check, maximum number check after counting the number of documents, connection check of RDH and finisher, document feeding end process, document number count, copy job start process, finisher to bin, transfer paper discharge count to tray, stapling This includes operation execution, stapling operation end processing, document ejection processing, and document ejection termination processing. Hereinafter, each control item will be described in detail.

7.2 Check at the time of key input (mode setting by the operator) On the operation plate (FIG. 74) of the copying machine main body 3, a reservation selection key (mode selection key) 385, staple mode, sort mode, and stack mode are provided. LE D387 and the like shown respectively are provided, and the LED 387 corresponding to the mode is turned on and off in response to the pressing operation of the reservation selection key 385.

In this check, roughly, the staple check is performed by turning on the mode select key for the first time, and if the staple is possible, the staple LED is turned on. If it is not possible, that fact is displayed on the display and a sort check is performed. If staples are possible and the key is pressed again, the sort check is performed. (Staple LED OFF at this time) If sorting is possible, the sorting LED is turned on, and if not, that effect is displayed on the display and stack check is performed. When sorting is possible, stack check is performed even if the key is pressed again. (Sort LED OFF at this time) If stacking is possible, the stack LED is turned on, and if not, the fact is displayed on the display and the staple check is performed. (Even if stacking is possible, if the key is pressed once again, all the LEDs are turned off.) The above checks are repeated each time the mode select key is pressed. The mode in which the LED is lit when the print key is turned on and when the reservation mode is set is finally selected, and when no LED is lit, normal transfer paper processing is performed (except for the selected mode, Set a prohibition flag).

This will be described in more detail with reference to the flowchart of FIG. As can be seen from this flow chart, when the mode select key is pressed (step S1), it is first checked whether or not each connection flag is "1" (step S2). Each connection flag is a flag for checking whether the finisher 11 and the RDH 9 are connected.

When it is confirmed in step S2 that the finisher 11 and the RDH 9 are connected, a staple check is performed by the first key ON, and if staple is possible, the staple LED is turned on (step S3). If the staple LED is turned on in step S3, the staple LED is turned off as shown in the flowchart of FIG. 51 (step S4), the staple inhibition flag is set to "1" to inhibit the staple, and the sort or stack mode is set. The process moves (step S6).

Then, it is checked whether or not the sort bin jam flag indicating that a jam has occurred in the bin 37 is "1" (step S7). If it is "1", a jam has occurred. Therefore, the sorting is prohibited and the stack is prohibited (steps S8 and 9), and "sort not possible" and "stack impossible" are displayed on the display (step S10).

When the sort bin jam flag is not set to "1" in step S7, no jam has occurred in the bin 37, so it is checked whether the mode is the reservation mode described later (step S11). If it is the reservation mode, a maximum value check subroutine (MAX check 1), which will be described later, is executed (step S12), and it is confirmed by a flag whether sorting is prohibited (step S13). If it is determined by this check that the sort prohibition flag is set, "Sorting is not possible" is displayed on the display (step S14), and the processes after step S21 described below are executed. It is turned on (step S17).

On the other hand, if it is not the reservation mode in step S11, it is checked in step S15 whether or not there is numerical data. If there is register data, the processing from step S12 is executed. If there is no register data, the sort prohibition flag is set to "0" (step S16) to enable sorting and the sort LED is turned on. (Step S17).

When the staple LED is not turned on in the judgment of step S3, it is checked whether or not the sort LED is turned on (step S18). If it is ON, as shown in the flow chart of FIG. 52, the sort LED is set to OFF (step S19) and the sort prohibition flag is set to prohibit sort (step S20). It is checked whether there is any (step S21). If there is register data in this check, the maximum value check subroutine (MAX check 2) is executed (step S22), and it is further checked by the stack prohibition flag whether stacking is possible (step S23). If the stack prohibition flag is "1", "no stacking" is displayed on the display (step S24). If it is not "1", the stack LED is turned on (step S26). On the other hand, when it is determined in step S21 that there is no numerical data, the stack inhibition flag is set to "0" (step S25), and the stack LED is turned on (step S26).

If the sort LED is not turned on in step S18, it is checked whether the stack LED is turned on (step S27). If the sort LED is turned on, the stack LED is turned off (step S28). The stack inhibition flag is set to "1" (step S29) to inhibit the stack.

If the stack LED is not turned on in step S27, the staple mode is executed (step S30), the stapler check subroutine is executed (step S31), and then the staple inhibition flag is set to "1". It is checked whether or not (step S32). If the staple inhibition flag is not "1" in this check, stapling is possible, so the staple LED is turned on (step S33). On the other hand, if it is not "1", stapling is prohibited, and "stapling is not allowed" is displayed on the display (step S34), and the processing from step S6 is executed.

7.3 Stapler Check In this process, whether or not stapling is possible is checked under each condition.

FIG. 53 is a flowchart showing the processing procedure of this processing. In this process, first, the finisher connection flag indicating whether or not the finisher 11 is connected is checked (step S41). Then, when the finisher connection flag is "1" and it is determined that the finisher 11 is connected, it is checked whether there are staples in the stapler, that is, the staple end flag is checked (step S42). .. If it is determined in this check that the staple end flag is set, that is, if there is no staple, a staple prohibition flag is set (step S52), and staple is prohibited.

When it is determined that the staple end flag is down and there are still staples, the staple end LED is turned off (step S43), and it is checked whether the stapler jam flag is "1" (step S43). S44). If a jam is found in this check, stapling is prohibited (step S52). If it is not jammed, it is checked whether the staple is in an abnormal state (step S45). If the staple is abnormal in this check, stapling is prohibited (step S52). If it is not abnormal, it is checked whether the finisher door open flag is "1" (step S46). The finisher door open flag is a flag that becomes “1” when the door of the finisher 11 is opened due to jam removal or the like. If the finisher door open flag is set in this check, stapling is prohibited (step S52), and if it is not set, it is checked whether the mode is the reservation mode (step S47). If it is not the reservation mode, it is checked whether or not there is any remaining paper on the staple tray 55 (step S48). If this check determines that there is no remaining paper, the staple prohibition flag is set to “0” to enable stapling, and if it is determined that there is remaining paper, “Still tray has remaining paper” is displayed and stapling is possible. Since it is not in the state, stapling is prohibited (step S52). On the other hand, if the reservation mode is set in step S47, the document set flag is checked to see if the document OL is set on the bin 37 (step S49). If the original document OL is set in this check, the process from step S48 is executed, and if not set, the stapleable state is directly set in step S50.

7.4 Sort MAX Check when Inputting Numerical Values When not in reservation mode, all bins can be used. (20 bins in this case) When the number of registered units exceeds 20, the operator is notified by the guidance display. The number of usable bins in the reservation mode is the number of bins below the lowest bin in which the original is set. For example, in Figure 2, if the originals are set in the top, third, and fourth bins, the usable bins are located below the fourth to top bin. It is 16 bins. When the number of registered characters exceeds the number of possible bins, sorting is prohibited, and if the LED is lit, it is turned off and the display indicating that sorting is not possible is displayed.

This processing is shown in the flowchart of MAX check 1 in FIG. In this process, first, the numerical data is loaded in step S61. Next, it is checked whether or not it is the reservation mode (step S62), and if it is in the reservation mode, all the selection display LEDs (P1, P2, P3, P4) 387 of the five reservation selection keys 385 described later (FIG. 74) are all displayed. In the OFF state (when it is determined that all are OFF states in steps S63, 64, 65, 66), 0 is substituted for A (step S67), and further, as shown in FIG. -A) values are compared (step S68). When it is determined that the number is larger, the sort prohibition flag is lowered (step S71) to return to the sortable state, and the process returns. When it is determined that the number is larger, the sort prohibition flag is set. Standing up (step S69), sorting is prohibited, and it is determined whether or not the sort LED is turned on (step S70). If the sorting LED is OFF in this determination, the process returns. If the sorting LED is ON, the sorting LED is turned OFF (step S72), "not sortable" is displayed on the display (step S73), and then the process returns.

In this process, if the LED of P4 is ON in the check of step S66, 1 is substituted for A (step S74), and if the LED of P3 is ON in the check of step S65, If 2 is assigned to A (step S75), and the LED of P2 is ON in the check of step S64, 3 is assigned to A (step S76), and the LED of P1 is ON in the check of step S63. If so, 4 is substituted for A (step S77), and the process proceeds to step S68, where the register number and (20-A) are compared and the process proceeds to the next step.

If it is determined in step S62 that the reservation mode is not set, as shown in FIG. 55, in step S78, the register number is compared with the bin number of 20, and if the register number is larger, a guidance display subroutine is displayed. Is executed (step S79), the sort prohibition flag is turned off (step S80), the sort enabled state is returned, and when it is determined in step S78 that the number is not larger, the sort prohibition is solved (step S80). S80) Return.

The guidance display in step S79 is, for example, a display such as "Up to 20 copies can be sorted. The rest is sorted after removing the transfer paper."

7.5 Stack MAX Check When Inputting Numerical Values This process prohibits stacking when the numerical value exceeds the bin MAX (50 sheets in this case), and turns off the LED if the LED is on. This is a process for displaying "Unstackable" on the display.

Specifically, as shown in the flow chart of MAX check 2 in FIG. 56, first, the register data is loaded (step S91), and it is checked whether the register number is greater than 50 (step S92). If 50 or less sheets are stackable, the stack prohibition flag is set to "0" (step S93). If there are more than 50 sheets, the stacking is not possible, so the stack prohibition flag is set to "1" (step S94), and it is further checked whether the stack LED is ON (step S95). If the stack LED is in the OFF state by this check, it is clearly stated that the stack cannot be performed. If it is in the ON state, the stack LED is turned OFF (step S96), and the "STACK" is displayed on the display. "Not possible" is displayed (step S97), and the process returns.

7.6 MAX Check After Counting the Number of Documents In this process, when the number of documents exceeds the staple MAX and bin MAX (both 50 in this case), stapling and sorting are disabled. The number of effective bins in the stack is the same as that in the sorting of 3 above. When the number of effective bins is exceeded, it is disallowed. When the number of originals is 1, stapling is prohibited. When stapling and sorting are not possible, the transfer paper is discharged to the copy (proof) tray 39 as in the normal transfer paper processing. When stacking is not possible, the number of effective bins is stacked, and the rest is discharged to the copy (proof) tray 39. When not in the reservation mode, the fact is displayed on the display.

Specifically, it is shown in the flowchart of MAX check 3 in FIG. In this process, it is first checked whether or not the special mode is set (step S101), and if any one of the staple mode, the sort mode, and the stack mode is set, it is determined that the special mode is set and the number of originals exceeds 50. It is checked whether the number is large (step S102). If the number of originals is more than 50 in this check, the staple inhibition flag is set to "1" to inhibit stapling (step S103), and the sorting inhibition flag is set to "1" to inhibit sorting (step S104). ). Next, the stack prohibition flag is checked to see if it is in the stack prohibition state (step S105), and if it is not the stack prohibition, it is checked to see if it is the reservation mode (step S106). If it is in the reservation mode by this check, the Help flag for ejecting to the copy (proof) tray 39 is set to "1" as in the case of normal ejection (step S107), and the process returns.

If the check in step S106 indicates that the mode is not the reservation mode, for example, the guidance display that "up to 20 copies can be stacked. The rest will be stacked in the copy tray." Is displayed (step S108), and then return. To do.

If the stack is prohibited in the check in step S105, it is further checked whether the mode is the reservation mode (step S109). If it is the reservation mode in this check, the above-described processing of step S107 is executed, and if it is not the reservation mode, "stapling impossible" and "sorting impossible" are displayed on the display (step S110) and the process proceeds to step S107 and returns. To do.

On the other hand, when it is determined in step S102 that the number of originals is 50 or less, it is further checked whether the mode is the reservation mode (step S111). If the reservation mode is not set, the number of originals is 20. It is checked whether the number is larger than that (step S112). If it is determined that the number of originals is 20 or less, it is further checked whether the number of originals is 1 (step S113), and if it is not 1, the document is returned as it is, and if it is 1, it is as shown in FIG. A staple prohibition flag is set to prohibit stapling (step S114), a Help flag is further set (step S115), the sheet is ejected to the copy tray 39, and "staple prohibition" is displayed on the display (step S116). Then return.

When it is determined in step S112 that the number of originals is 20 or more, the processes in step S108 and subsequent steps are executed, and when it is determined in step S111 that the reservation mode is set, as shown in the flowchart of FIG. As in the flow chart of FIG. 54, if the selection display LEDs (P1, P2, P3, P4) 387 of the five reservation selection keys 385 are all in the OFF state (steps S117, 118, 119). , 120, it is determined to be OFF), 0 is substituted for A (step S121), and the numerical value and the value of (20-A) are compared (step S122). When it is determined that the number of copies is not larger, it is checked whether the number of originals is one (step S123). If the number of originals is one, it is not necessary to staple the sheets. Is set (step S124), the Help flag is further set (step S125), and the sheet is set to be discharged to the copy tray 39, and then the process returns.

When it is determined in step S122 that the number of copies is larger, the process proceeds to step S125 and subsequent steps, and when it is determined in step S123 that the number of originals is not one, the process directly returns.

In this process, when it is determined in step S120 that the LED of P4 is turned on, 1 is substituted for A (step S126), and the LED of P3 is turned on in step S119. If it is determined that A is set to 2 (step S127), and if it is determined in step S11 that the LED of P2 is ON, 3 is set to A (step S128), and P1 is set at step S11. When it is determined that the LED of is turned ON, 4 is substituted for A (step S129), the process proceeds to step S122, and the numerical value and (20-A) are compared, and the process after step S122 is performed. Run.

7.7 RDH / Finisher Connection Check The connection check of the RDH 9 and the finisher 11 is executed based on the flowcharts shown in FIGS. 59 and 60, respectively.

In the connection check process of the RDH 9, as shown in FIG. 59, it is first checked whether the RDH 9 is connected (step S131). If it is determined in this check that it is connected, the RDH connection flag is set to "1" (step S132). If it is not connected, the RDH connection flag is set to "0" (step S133), and the flag RDH is set to "0". (Step S134).

In the connection check processing of the finisher 11, first, as shown in FIG. 60, it is checked whether or not the finisher 11 is connected (step S141). If it is determined that the connection is made by this check, the finisher connection flag is set to "1" (step S142), and if not connected, the finisher connection flag is set to "0" (step S143), and the flag finisher is set to "0". “” (Step S144).

7.8 Document Feed from Finisher to RDH This process is performed when the previous reserved job is completed in the reservation mode, and there is no abnormality in the copying machine main body 3, finisher 11 and RDH 9. For example, the mode data and the bin position data are transmitted from the copying machine main body 3 side to the finisher 11 side, and the bin 37 feeds and discharges the sheet feeding path 135 to the feeding and discharging rollers 83 and 84 as shown in FIG. When it is set to 136, a signal is sent to the RDH 9, and when an acceptance OK signal from the RDH 9 is received, a document feeding start signal is sent to the finisher 11. The specific processing procedure is as shown in the flowcharts of FIGS. 61 and 62.

In this process, in the reservation mode (step S151), the connection flags of the finisher 11 and the RDH 9 are connected (step S152), the job end flag is "1" (step S153), and the RDH original set. When the flag is "1" (step S154), the message "Document remains on RDH. Please remove it" is displayed (step S155). If it is determined in step S154 that the RDH original set flag is not "1", it is checked whether each door open flag is "1" (step S156), and it is determined that the flag is not "1". If so, that is, if it is determined that all the doors are closed, it is checked whether or not each jam flag is "1" (step S157). In this check, if the jam flag is not "1", in other words, if there is no jam in any place, it is checked whether the RDH lift-up flag is "1" (step S158), and the RDH lift-up flag is set. When it is confirmed that the vehicle has descended, the mode data and the bin position data are transmitted from the copying machine main body 2 side to the finisher 11 side (step S159). The mode data is “101”.

When the data is transmitted in step S159, it is checked in step S160 whether the bin position data of the copying machine main unit 3 and the bin position data of the finisher 11 match, and if they match, the original set flag is set. It is checked whether it is "1" (step S161). If they match, the original set flag is set to "1" (step S162), and the original acceptance OK flag is set to "1" to check whether the original can be accepted (step S162). S163). When it is determined that the original can be received, the original feeding flag is set to "1" to enable the original feeding (step S164), and the job end flag is set to "0" to set the job execution state ( After step S165), the process returns. The job end flags in steps S153 and S165 are flags that are set to "1" when the previous reserved job is completed and when the job is initialized.

7.9 Original Feeding Finishing Process This process is a process of stopping the finisher 11 and the RDH 9 after 0.5 seconds if the document number data from the finisher 11 and the document number data from the RDH 9 match. Specifically, it is as shown in the flowchart of FIG. 63.

In this process, when the mode is the reservation mode (step S171), the RDH original reception flag and the original feeding flag are both "1" (steps S172 and 173), and the original set flag is not "1". (Step S174), the document number data 1 which is the number of documents counted by the finisher 11 and the document number data 2 which is the number of documents counted by the RDH 9 are loaded (steps S175 and 176), and both document number data are equal. Is checked (step S177).

If the number-of-documents data matches in this check, the number-of-documents data is cleared (step S178), the 0.5 second delay routine is executed (step S179), the document feeding flag is set to "0", and RDH is further set. The document acceptance flag is set to "0" so that the document is not sent from the finisher 11 to the RDH 9 (steps S180, 181).

7.10 Original Document Counting Process When the original is directly placed on the RDH 9 and copied in the reservation mode, the number of originals is counted. In this case, when the signal of the original set is received, the mode data is transmitted to the RDH 9 and the number of originals is counted. Specifically, the procedure is shown in the flow chart of FIG.

In this process, the original mode is not set in the reservation mode (step S191) and the originals are set in the RDH 9 (step S192). However, there is no original number data (step S193), and the number of originals should be counted. No (step S194), the RDH 9 has not been lifted up (step S195), the door has not been opened to remove the jam (step S196), and the jam is not located anywhere on the finisher 11, the RDH 9 and the copying machine main body 3. Also, the mode data “0001” is transmitted to the RDH 9 on the condition that no occurrence has occurred (step S197). 7.11 Copy job start process If the originals are set on the RDH 9 and the number of originals has been counted, the copy job is started. When the original set signal is received from the RDH 9, the mode data set by the operator and the bin position data corresponding to the mode are sent to the finisher 11. When the bin is set, the mode data is sent to the RDH 9 and the original file is sent. Start the buy-in. Specifically, it is shown in the flowcharts of FIGS. 65 and 66.

In this process, the finisher 11 and the RDH 9 are connected (step S201), no jam has occurred (step S202), the door is closed (step S203), and the RDH 9 is lifted. If it is confirmed that the document is set on the document setting table 217 (step S205), it is further checked whether it is the reservation mode (step S206). When it is determined in step S206 that the mode is the reservation mode, the bin position data and the mode data are directly transmitted to the finisher 11 (step S207), and when it is determined that the mode is not the reservation mode, it is checked whether there is document number data (step S208). ), If there is no data on the number of sheets, the process returns, and if so, the process proceeds to step S207 to check whether the mode has ended (step S209). If the mode is completed, the mode data of sort, stack, staple, double-sided original, double-page original, etc. is transmitted to the RDH 9 (step S210), and whether the special mode such as staple mode, sort mode, stack mode is used. Check (step S211), check each prohibition flag in the special mode (step S212), and set the feed-in flag to "1" (step S213) if not in the prohibition state. Feed it in. If the special mode is not set in step S211, step S212 is skipped and the process of step S213 is executed.

7.12 Transfer Paper Ejection Counting Process to Finisher Bin and Tray This process counts the number of ejected sheets in response to the sheet ejection signal from the finisher 11. In the staple mode, the count number is the number of originals. When the count value matches the registered number data in other modes, it is considered that the final paper has been ejected. In the modes other than the staple mode, the final paper discharge is further counted, and if the count number matches the number of documents, it is considered that the final paper in one job has been discharged (copy job end). Specifically, it is shown in the flow chart of FIG.

In this process, first, the sheet discharge flag is set to "1", and if the sheet discharge state is set (step S221), 1 is added to the sheet discharge counter 1 (step S222), and it is checked whether the staple mode is set. (Step S223). If it is determined in step S223 that the staple mode is set, it is checked whether or not the number of documents matches the number of sheets in the sheet ejection counter 1 (step S224). It is checked whether the values match (step S225). If they do not match, the process returns, and if they match, the final paper discharge flag 1 is set (step S226). Then, the sheet discharge counter 1 is cleared (step S227), and it is checked whether the staple mode is set (step S228). If the staple mode is not set in this check, 1 is added to the sheet discharge counter 2 (step S229), and it is checked whether the number of originals matches the sheet discharge counter 2 (step S230). If they match, the final sheet has been ejected, so the final sheet ejection flag 2 is set (step S231) and the sheet ejection flag 2 is cleared (step S232).

7.13 Staple Operation Execution Processing In this processing, when the staple mode is selected and the last sheet is ejected, the prohibit flag is checked and the staple operation is executed (the staple flag is set to “1”). Yes) processing. The specific processing procedure is shown in the flowchart of FIG.

In this process, first, it is checked whether the staple mode is set (step S241), and if the staple mode is selected, it is confirmed by the final discharge flag whether the last sheet is discharged (step S242). Then, when it is confirmed that the final sheet has been ejected, whether or not to perform stapling is checked by the stapling prohibition flag (step S243). If it is determined in this check that stapling is to be performed, the stapling flag is set to "1" to perform the stapling operation (step S244). If stapling is not to be performed, the staple flag is set to "0" and stapling is performed. It is prohibited (step S245).

7.14 Staple Operation Completion Processing In this processing, after the stapling execution signal is transmitted to the finisher (stapler) 11, the stapler 11 finishes the stapling operation (until the stapled transfer paper is dropped to the discharge stocker 57). When the signal of is received, the staple flag is set to "0" and the staple counter is incremented. Specifically, the processing procedure is shown in the flowchart of FIG.

In this process, first, it is confirmed whether the staple mode is set (step S251). If the staple mode is set, it is checked whether the staple flag is "1" (step S252). If stapling is being performed by this check, that is, if it is "1", it is checked whether the copy drop OK flag is "1" (step S253). If the copy drop is OK, the staple flag is set. It is set to "0" (step S254), 1 is added to the staple counter (step S255), and the final paper ejection flag is set to "0" (step S256).

7.15 Document Ejection In this process, if the copy job is completed in the reservation mode and there is no abnormality, the bin position data and mode data are transmitted to the finisher 11, and the bin 37 supplies and ejects paper. If there is no original on RDH9 at this time, it is considered that the original has been removed by the operator and the reserved job is considered to have ended, the mode data of the completed job is cleared, and preparation is made from RDH9. When the completion signal is received, the document discharge operation is started. The specific processing procedure is shown in the flowcharts of FIGS. 70 and 71.

In this processing, the mode is the reservation mode (step S261), the staple mode (step S262) and the number of copies is equal to the value of the staple counter (step S263), or the staple mode (step S262). However, the final paper discharge flag 2 is set (step S264), no jam has occurred (step S265), no door is opened (step S266), and the RDH 9 is lifted. The bin position data and mode data “110” are transmitted to the finisher 11 (step S268) on condition that the bin position data has not been updated (step S67), and it is further confirmed whether or not the bin position data is the same as the bin finisher position data. (Step S269). If they are equal, the mode data “0010” is transmitted to the RDH 9 (step S270), and it is checked whether or not the original is set on the RDH 9 (step S271). If the originals are set, it is checked whether the originals can be sent from the RDH 9 to the finisher 11 side (step S272). If the originals can be sent, the originals can be sent from the RDH 9 to the finisher 11. The original discharge flag is set to "1" so that the original can be sent (step S273), and the original RET flag is set to "1" so that the original can be fed from the RDH 9 to the finisher 11 (step S274).

On the other hand, if it is determined in step S271 that no document is set in the RDH 9, a job end flag is set to end the reserved job (step S275), and stapling cannot be performed, so the staple counter is cleared. (Step S276) After setting the final paper discharge flags 1 and 2 to "0" (step S277), the mode data of the reserved job that has ended is cleared, and the reserved LED is turned off (step S278).

7.16 Original Ejection End (Reservation Job End) Processing This processing is to wait 0.5 seconds after the original (eject) number data from the RDH 9 and the original number data from the finisher 11 match. This is a process of terminating the operation No. 1, deciding that the reserved job has ended, and clearing the mode data of the completed job. The specific processing procedure is shown in the flowchart of FIG.

In this process, first, in the reservation mode (step S281), the document discharge flag sent from the copying machine main body 3 side to the RDH 9 is "1", that is, the document is sent from the RDH 9 to the finisher 11. (Step S282), the document return flag sent from the copying machine main body 3 side to the finisher 11 is "1", that is, the RDH9 is ready to send the finisher 11 document (Step S283), and the document is set on the RDH9. If not (step S284), the original number data 2 which is the number of originals counted by the RDH 9 and the original number data 1 which is the number of originals counted by the finisher 11 are loaded (steps S285, 286). Next, the number of loaded originals is compared (step S287), and if they match, the data of the number of originals is cleared (step S288), a 0.5 second delay routine is executed (step S289), and the original discharge flag and The original return flags are set to "0" to stop the conveyance of the original from the RDH 9 to the finisher 11 (steps S290, 291). Then, the reserved job end flag is set to "1" to end the reserved job (step S292), the mode data of the completed reserved job is cleared, and the reserved LED is turned off (step S293). Then, the staple counter is cleared (step S294), the final paper ejection flags 1 and 2 are set to "0" (step S295), and this process is ended.

Note that FIG. 73 shows a comparison between copying in the reservation mode and normal copying in these processes.

7.17 Setting Reservation Mode FIG. 74 shows a part of the operation unit of the copying machine main body 3. This operation unit includes a print key 373, a group of keys such as an interrupt key 375 arranged above the print key 373, a mode clear key 377, a reservation mode key 379, and an enter key 381, and a key arranged on the left side of the print key 373. Ten key clear / stop key 383 group, reserved selection keys 385 group P1, P2, P3, P4, P5 arranged above the ten key clear / stop key 383 group, and an upper portion of the reservation selection key 385 A group of LEDs 387 indicating the selection state of P1, P2, P3, P4, and P5 arranged in, a reservation reception LED 389 indicating a reservation reception state, and a reservation error LED 391 are provided.

The reservation mode is set by using the keys of the operation unit as described above. Specific setting processing is shown in the flowcharts of FIGS. 75 to 79.

As can be seen from this flowchart, the reservation mode setting starts by checking ON / OFF of the reservation mode key 379 (step S301). If it is determined that the reservation mode key 379 is ON in step S301, ON / OFF of the reservation acceptance LED 389 is checked (step S302). If the reservation acceptance LED 389 is OFF, the reservation acceptance LED 389 is made to blink (step S303), the three-digit code entered with the ten keys 383 is accepted (step S304), and the mode clear key 377 is turned ON / OFF. Is checked (step S305). If the mode clear key 377 is OFF in this check, it is checked whether any key P385 of P1 to P5 is ON (step S306), and if ON, the corresponding LED 38 of any of P1 to P5 is checked. It is checked whether 7 is OFF (step S307-FIG. 76).

If the LED 387 is OFF in this check, the LEDs 387 corresponding to P1 to P5 are blinked (step S308), and the reservation acceptance LED 389 is turned on (step S309). Next, the 3-digit code data received in step S304 is stored in the memory (step S310), and the code input flag indicating that the code has been input is set to "1" (step S311). Perform (step S312). When the mode is set, a mode check process is executed (step S313) and it is checked whether this process is completed (step S314). If the processing is completed, it is further checked whether or not the mode clear key 377 is turned on (step S315), and if not, the mode clear processing is executed (step S316).

After executing this processing, the timer 1 is stopped and cleared (step S317-FIG. 77), the timer 1 start flag is set to "0" (step S318), and it is checked whether the enter key 381 is turned on. (Step S319). When the enter key 381 is turned on by this check, the LED 387 corresponding to the corresponding P1 to P5 is turned on (step S320), the reservation acceptance LED 389 is turned off (step S321), and the mode data and the number of units are set. Store in memory (step S322) and return.

On the other hand, when the mode clear key 377 is turned on in step S315, it is checked whether the enter key is turned on (step S323-FIG. 78), and if it is turned on, the timer 1 start flag is set to " It is checked whether it is "1" (step S324). If it is not "1", the timer for 0.5 second is started, the timer 1 start flag is set to "1", and the process returns (step S325). If the timer 1 start flag is "1" in step S324, it is checked whether the timer 1 is counting up (step S326). If it is determined that the timer is not counting up in this check, it is returned as it is, and if it is counting up, the mode setting corresponding to the corresponding P1 to P5 is cleared (step S327). The LED 387 corresponding to the corresponding P1 to P5 is turned off (step S328), and the reservation acceptance LED 389 is also turned off (step S329). After that, the code input flag is set to "0" (step S330), the timer 1 is stopped and cleared (step S331), the timer 1 start flag is set to "0" (step S332), and then the process returns. If the enter key 381 is not turned on in step S323, the processing of step S331 and subsequent steps is executed as it is.

If the processing is not completed in the check in step S314, it is checked whether or not the number of characters is over in each mode, whether there is paper, and the like (step S333). Then, the ON / OFF state of the mode clear key 381 is checked (step S334). If this check is ON, the above-described processing of step S323 and thereafter is executed, and if OFF, the processing of step S312 and thereafter is executed.

If the LED is ON in the check of step S307, it is checked whether the corresponding LED 387 of P1 to 5 is blinking (step S335). If it is blinking, the LED 387 is checked. Is turned off (step S336), and the 3-digit code data in the memory is cleared (step S337). After that, the code input flag is set to "0" (step S338), the mode all clear processing is performed to clear all the modes (step S339), the reservation acceptance LE D389 is blinked (step S340), and the process returns.

If the corresponding LED 387 is not blinking in the check in step S335, the 3-digit code data is loaded from the memory (step S341), and the input 3-digit data is converted into the 3-digit data from the memory. (Step S 342). If the two coincide with each other in this comparison, the corresponding LED 387 is blinked (step S343), the stored mode data is loaded (step S344), and the setting is performed according to the mode data (step S345). The code input flag is set to "1" (step S346), the reservation acceptance LED 389 is turned on (step S347), and the processing from step S312 is executed.

If the mode clear key 377 is ON in the check in step S305, the 3-digit code data is cleared (step S348), and the process returns, and in step S306, the reservation selection key 385 is OFF. If so, return as is.

If both mode data are not equal in the check in step S342, the mode data is cleared in step S348 and the process returns. In this case, the reservation error LED 391 and other LEDs may be set to be turned on for a certain period of time before proceeding to step S348.

Further, if the reservation acceptance LED 389 is turned on in the check of step S302, it is checked whether the reservation acceptance LED 389 is blinking (step S349-FIG. 79), and if not blinking, it is applicable. The LED is turned off (step S350), the 3-digit code data in the memory is cleared (step S351), and the code input flag is set to "0" (step S352). Then, the mode all clear process is executed (step S353), the reservation acceptance LED 389 is turned off (step S354), and the process returns. If the reservation acceptance LED 289 is blinking in step S349, the reservation acceptance LED 389 is turned off and the program returns in step S354.

If the reservation mode key 379 is OFF in the check in step S301, it is confirmed whether or not the code input flag is "1" (step S355). For example, the processing of step S312 and subsequent steps is executed, and if not, the blinking of the reservation acceptance LED 389 is further checked (step S356). If so, return as it is.

8. Control Regarding Document Feeding Device 8.1 Checking Whether RDH Is Lifted Up The check for lift-up of RDH9 is performed based on the processing procedure of the flowchart of FIG. In this processing procedure, first, ON / OFF of the lift-up sensor is checked (step S401). If the lift-up sensor is ON in this check, the RDH lift-up flag is set to "1" (step S402), and if OF-F is set, the RDH lift-up flag is set to "0" (step S403). It is transmitted to the machine body side (step S404).

8.2 Checking whether or not the document exists at the paper feed position of RDH Since copying cannot be done unless the document exists at the paper feed position of RDH9, it is checked whether the document exists at the paper feed position. There is a need to. This processing procedure is performed based on the flowchart of FIG.

In this process, first, ON / OFF of the document set detection sensor is checked (step S411). If the original set detection sensor is ON in this check, the RDH original set flag is set to "1" (step S412), and if the original set detection sensor is OFF, the RDH original set flag is set to "0" (step S413). It is transmitted to the main body 3 side (step S414).

8.3 Clear Processing by Lift-Up If the RDH 9 is lifted-up, the original cannot be fed, so the clear processing is performed. Specifically, it is performed according to the flowchart of FIG. That is, first, it is checked whether the RDH lift-up flag is "1" (step S421), and when it is confirmed that the RDH 9 is lifted up, the feed end flag is set to "0" (step S422). Although only the feed end flag is cleared in this flow chart, the feed number counter, the jam flag, etc. are also cleared and the motor is turned off.

8.4 Multi-Job Support Processing When performing multi-jobs using the RDH9, if the RDH9 is lifted up in the middle of the job, it may become impossible to operate, or it may become incomplete. , Basically, lift up is prohibited except when jamming. Specifically, as shown in the flowchart of FIG. 83, first, the interrupt flag is checked (step S431), and if the interrupt flag is not "1", the process is compatible with multi-jobs, so the RDH lift is performed. The up flag is checked (step S432). If the RDH lift-up flag is not "1" in this check, that is, if the RDH 9 is not lifted up, it is further checked whether or not the document is jammed at feed-in (step S433). Next, it is checked whether or not a jam has occurred at the time of feed-out (step S434). If it is not jammed, the reverse jam flag is further checked (step S435). If it is not jammed, the lift-up lock solenoid (pressure plate solenoid) 279 is turned on to lock the RDH (pressure plate) 9 to perform a multi-job. Let it run.

On the other hand, when the interrupt flag is “1” in step S431, it means that the job is not compatible with multi-jobs, and therefore the lift-up solenoid 279 is turned off to release the lock (step S437). Similarly, if the RD H9 is lifted up in the check in step S432, if the original feed-in state is jammed in the check in step S433, or if the original feed-out state is jammed in the check in step S434. In this case, and when the reverse jam flag is set to "1" and the original is jammed in the reverse process, the job cannot be executed as it is. Therefore, the lift-up solenoid 279 is also turned off to release the lock (step S437).

8.5 Sheet Drop and Misalignment Prevention Processing When the RDH 9 is lifted up, the document at the paper feeding position on the RDH 9 may be misaligned or dropped from the paper feeding position. It is set so that the closing roller solenoid 239 shown in FIG. 28 is turned on to press the original on the original setting table 217 side by the closing roller 235, and the original is sandwiched and held between the two. This processing is shown in the flowchart of FIG.

In this process, the lift-up of the RDH 9 and the setting of the document are checked (steps S441 and 442), and the RDH 9 is lifted up, and when the document is set, the shift roller solenoid 239 is turned ON (step S441). S443) The document is held between the shifting roller 235 and the document setting table 217 so that the document does not fall and is not displaced.

8.6 Document Number Counting Process It is described with reference to FIGS. 40 and 41 when the user directly places the document on the document set table 217 of the RDH 9 instead of the one sent from the finisher 11 side. It may be necessary to count the number of documents. This specific processing is shown in the flowchart of FIG. 85 and will be described with reference to this flowchart.

This process starts when the mode data is 1 (step S451). That is, if the mode data is 1, the flag for counting the number of sheets is checked (step S452), and if the number of sheets is not being checked, the value of the sheet counter is further checked (step S453). If the number counter is 0 in the check in step S453, the number counter is set to "0" (step S454), the number counting flag is set to "1" to enable the number counting (step S455), and further. The job end solenoid is turned on (step S456) to execute a subroutine for counting the number of sheets (step S457). Then, the number counter is set to "1" (step S58), and if the job end detection sensor is ON (step S459), the number counting flag is set to "0" (step S460) and the job end solenoid is turned on. It is turned off (step S461), and the number data and the size data detected by the resist detection sensor are transmitted to the copying machine main body 3 side (step S462).

If the number-of-sheets-counting flag is 1 in step S452, the process skips to step S457 and the subsequent processes are executed. When it is not "0" and when the job end detection sensor is not ON, the process directly returns.

8.7 Feed-in processing and feed-out processing Select the feed-in timing and the feed-out timing of the document according to the feed-in flag and feed-out flag transmitted from the copying machine main body 3 side and the state of the RDH 9. And run. Specifically, it is processed as shown in the flow charts of FIGS. 86 and 87.

In this process, first, the feed-in flag is checked (step S471), and if the feed-in flag is "1" and the document is fed on the contact glass 7, the feed is performed. The out flag is checked (step S472). If the feed-out flag is not "1" and the document is not fed out from the contact glass 7, the feed end flag is further checked (step S473). If the feeding is not completed in the check in step S473, the document is fed in (step S474). This operation is performed at the timing shown in the timing chart of FIG. When step S474 is executed and the feed-in process is completed (step S475), the copy start flag is set to "1" (step S476) to set the copy start state, and the size data and the copy start flag are set to the copying machine main body 3 side. (Step S477), the feed end flag is set to "1" (step S478). The timing chart of FIG. 88 corresponds to the timing of the processes of steps S474 to S478.

If the feed-in flag is not set to "1" in step S471 and the document is not fed on the contact glass 7, the feed-out flag is further checked (step S479). ). In this check, if the feed-out flag is "1" and the document is ready to be ejected from the contact glass 7, the feed end flag is checked (step S480), and the feed end flag is " If it is 1 ", the feedout process is executed by the timing shown in FIG. 90 (step S481). Then, when the feed-out process is completed (step S482), the feed end flag is set to "0". The timing chart of FIG. 90 corresponds to the timing of the processing in steps S481 to S483.

Further, when the feed-out flag is “1” in step S472 and the feed-out is performed from the contact glass 7, and in step S473, the feed-end flag is set to “1” and the feed-end state is set. In some cases, as shown in FIG. 87, the feed-in / feed-out process is performed in step S484, that is, the feed-in process is performed in one direction and the feed-out process is performed in parallel with this, and the feed-out process from the contact glass 7 is performed. Is confirmed (step S485), the feed end flag is set to "0" (step S486), and the feed-in / feed-out process is executed again (step S487). When it is confirmed that the feed-in is completed (step S488) and the original is set on the contact glass 7, the copy start flag is set to "1" and copying is executed (step S489), and the size data and the copy start flag are copied. The data is transmitted to the machine body 3 side (step S490), the feed end flag is set to "1" and the feed end state is set (step S491). The timing chart of FIG. 89 corresponds to the timing of the processes of steps S484 to S491.

8.8 Operation Timing of Document Feeder Next, details of the timing charts of FIGS. 88 to 90 will be described. This timing chart is composed of three timing charts: timing 1 showing feed-in timing, timing 2 showing feed-in / feed-out timing, and timing 3 showing feed-out timing.

First, in FIG. 88, when the feed-in signal is received from the copying machine main body 3 side, the approach roller 235 and the feeding / discharging (conveying motor) are turned ON. After a delay of A time, that is, at the delay time A, the calling (half-month) roller 233 starts rotating, and at the same time, the paper feed clutch is turned on. Further, the original is pulled in according to the rotation of the calling roller 233, the leading edge is detected by the leading edge detection sensor, and then the original is fed in. Then, the calling roller 233 stops after making one rotation, and in synchronization with this stop, the shifting roller 235 also stops, and at the same time, the turn roller motor starts to rotate and the turn roller 227 rotates. It is transported to the transport belt 223 side. Then, after a lapse of B time from when the leading edge of the document is detected by the registration detection sensor, the belt motor that drives the document conveying belt 223 is turned on, and the document is sent onto the contact glass 7.

In this process, when the document passes the leading edge detection sensor, that is, when the trailing edge of the document passes the leading edge detection sensor, the detection output falls, and at the timing of this trailing, the paper feed clutch and the feeding / discharging motor operate. When the document is turned off, the document is transported by the turn roller 277 and the document transport belt 223. Then, at the fall of the detection output of the registration detection sensor, it can be seen that the original has passed the registration detection sensor position, that is, the position of the turn roller 277. At this timing, the turn roller motor becomes OFF and the turn roller 277 stops. .. Then, when C time has elapsed from this timing, the belt motor is turned off, the original conveyance belt 223 is stopped, the copy start flag is output, and copying is started.

Note that the length of the document in the conveyance direction is detected by the ON time of the leading edge detection sensor, and in the document number counting mode in which the number of documents is counted without copying, it is supplied at the timing indicated by H. The paper operation ends. This operation has already been described with reference to FIG. 35, and each switching claw is in the state described with reference to this figure.

The feed-in / out processing for performing feed-in and feed-out in parallel is performed subsequent to the feed-in, as shown in the timing chart of FIG. That is, when there is a document already fed on the contact glass 7 and the next document is fed from this state, the feed-in signal and the feed-out signal are transmitted together from the copying machine body 3 side. By inputting these signals, the RDH 9 side gives priority to the feedout process. Therefore, in this process, first, as shown in FIG. 36, the eighth switching claw 261 is switched to close the conveyance path 257 along the turn roller 227 and open the document return conveyance path 225. At the same time, the shifting roller 235 is turned on to prepare the document for feeding, the conveyance motor is turned on, and then the belt motor is rotated in the reverse direction. As a result, the document conveying belt 223 rotates in the opposite direction, and the document is discharged from the contact glass 7, that is, the feed-out is started. Then, when the turn roller 227 is rotated in the reverse direction and the registration detection sensor detects the leading edge of the document when it is discharged, the paper feed clutch is engaged, the calling roller 233 is turned on, and the document feed-in is started.

Then, after detecting the leading edge of the original being fed in by the leading edge detection sensor, after a preset D time, when the leading edge of the original comes just before the turn roller 227, the closing roller 235 is stopped. , Stop the paper feeding operation once. This is because the calling roller 233 for pressing the calling roller 233 at the time of paper feeding also serves as the pressing roller for the discharged paper. During this time, the feed-out operation is continued, and at the timing of time I when the trailing edge of the document to be ejected has passed the register detection sensor, the ejection sensor is turned on and the eighth switching claw 261 moves the conveying path 257 on the turn roller 227 side. Is opened to switch the document return transport path 225 side to the closed side, the paper feed clutch is turned on, the turn roller motor is normally rotated, and the belt motor is stopped. Then, when the preset B time elapses after the leading edge of the fed document is detected by the registration detection sensor, the belt motor rotates in the normal direction to rotate the document transport belt 223 in the forward direction, and the document is scanned. Feed in on the contact glass 7.

On the other hand, when the discharge detection sensor detects that the document is discharged to the document setting table, the shift roller 235 is turned on and the turn roller motor is turned off to align the discharged document after E time has elapsed. Due to the alignment of the discharged documents, the discharge clutch for the shifting roller 235 is turned off, and at the same time, the feeding / discharging motor is also turned off. Thereafter, the belt motor is turned off after a lapse of C time from the turning off of the turn roller motor, and when there is no original to be re-fed, the timing chart of timing 3 in FIG. 90 is entered.

At the timing of timing 3 shown in the timing chart of FIG. 90, when the feed-out signal from the copying machine main body 3 side is received, the eighth switching claw 261 is switched, and the document conveyance path 257 along the turn roller 227 is switched. Is closed, and the original return transport path 225 is opened. At the same time, the approach roller 235 is turned off, and then the belt motor starts reverse rotation. As a result, the document is discharged from the contact glass 7, the feeding motor is turned on, and the turn roller 227 starts reverse rotation. When the registration detection sensor detects the leading edge of the document in the ejection direction (the trailing edge of the document), the trailing edge of the fed-out document has reached the registration detection sensor position, so the paper ejection clutch is turned on. At the timing when the registration detection sensor detects the trailing edge of the document in the ejection direction, the ejection detection sensor is turned on, both the turn roller motor and the belt motor are turned OFF, and the roller 235 is moved to the E time after ejection to the document setting table 217. After ON and F hours, the paper discharge clutch and the paper supply / discharge motor are turned off to align the documents after they are discharged.

Although there is no description in these timing charts when aligning the documents on the document set table 217 due to the feed-out, the jogger fence 231 can be interlocked to perform the alignment.

8.9 Original Size Detection Processing The original size detection (APS) is performed by detecting the width of the original by the size detection sensor and counting the length by the number of pulses within the ON time of the registration detection sensor. Width detection is performed for documents with the same length but different widths. The size of the original is determined according to the procedure shown in the flowchart of FIG. 91 based on the combination of the width and the length, and the size data is transmitted to the copying machine main body 3 side at the OFF timing of the registration detection sensor.

In this process, first, it is checked whether the length of the document is longer than 406 mm (step S501). If this check is long, it is A3 (vertical) size as can be seen from the explanatory view of FIG. 92 (step S502). If it is 406 mm or less, it is checked in step S503 if it is longer than 306 mm. If it is longer, the size is B4 (vertical) size (step S504). If the length is 306 mm or less, it is further checked whether it is longer than 293 mm (step S505). If it is longer, it is A4 (vertical) size (step S506). It is checked whether it is long (step S507). In this check, if it is longer than 250 mm, it is B5 (vertical) (step S508), and if it is 250 mm or less, it is further checked whether it is longer than 200 mm (step S509). If it is longer, it is further checked whether or not the size detection sensor (the sensor attached to the position clearly indicated as the document width detection attachment position in FIG. 92) is turned on (step S510). If the size detection sensor is ON in this check, it is A4 (horizontal) (step S511), and if it is OFF, it is A5 (vertical) (step S512). If there is, it is further checked in step S513 whether the length of the document is longer than 182 mm. If it is 182 mm or less in this check, it is determined to be A5 (horizontal) (step S514), and if it is long, it is further checked whether or not the size detection sensor is ON (step S515). If it is ON, there is a portion longer than the installation position of the size detection sensor, so it is B5 (horizontal) as can be seen from FIG. 92 (step S516), and if it is not ON, B6 (vertical). (Step S517).

8.10 Jogger Home Return Process As described above with reference to FIG. 27, the jogger fence of the RDH9 is provided with a pair of jogger fences 231h and 231v for aligning the originals in the horizontal and vertical directions, respectively. The jogger motors 265h and 265v are driven via wires 267h and 267v, respectively. These jogger fences 231 are evacuated once in the initial state and when the job ends. At this time, the jogger counter is set to "0" and its retracted position becomes the reference position for jogging. This processing will be specifically described with reference to the flowchart in FIG.

In this process, first, the jogger home return flag is checked (step S521). If the jogger home return flag is "1" in this check, the jogger fence 231 is in the state of returning to the home position position, so this time, the jogger home position sensor configured by the photo interrupter is at the "H" level. It is checked whether or not is set (step S522). If it is not at "H" level, the jogger fence 231 has not returned to the detection position of the jogger home position sensor, that is, the home position. Therefore, in step S523, the jogger reverse flag is set to "0", and the jogger forward drive The flag is set to "1", and the rising signal of the jogger home position sensor is checked in step S524. If the detection signal of the jogger home position sensor rises, the jogger fence 231 is driven in the returning direction by 5 pulses (step S525). , The jogger reverse flag is set to "0" (step S526) to return to the home position.

On the other hand, when the jogger home position sensor is at the “H” level in the check in step S522, the jogger fence 231 has returned to the home position, so the jogger reverse flag is set to “0” and the jogger forward is set. Set the flag to "1" (step S527), check the fall signal of the jogger home position sensor (step S528), and if the jogger home position signal falls, set the jogger forward flag to "0" (step S529). , The jogger counter is reset (step S530), and the jogger home return flag is set to "0" (step S531).

As for the relationship between the jogger fence 231 and the jogger home position sensor, the home position of the jogger fence 231 is the moment when the jogger fence 231 leaves the home position sensor. Jogging of the original is controlled by the value in the jogging memory of the jogger counter. As described above, the jogger fence 231 includes the horizontal jogger fence 231h and the vertical jogger fence 231v. However, since the operation and the processing method are the same in both, the reference numeral 231 generally indicates both. Show.

8.11 Jogging Standby Process of Jogger When a document is sent from the finisher 11, the sheet size data detected by the size detection sensor on the finisher 11 side is sent from the copying machine main body 3 side. The jogger fence 231 moves to the jogger standby state according to the sheet size data. The jogger standby state is the position of the sheet size length + α, and the skew of the document to be jogged and the lateral registration are adjusted. This process is shown in the flowchart of FIG.

In this process, first, the acceptance OK flag indicating that the document is fed from the finisher 11 side is "1" (step S541), and the jogging flag indicating that jogging is being performed is "1". "(Step S542), the sheet size data of the document to be jogged is present (step S543), and the jogging data is selected from the sheet size data by referring to the data table (step S544-). Standby state). Then, jogging data is put into the jogging memory (step S545), and it is checked whether the value of the jogger counter is equal to the value of the jogging memory (step S546).

If the values of both companies are equal in the check in step S546, both the jogger reverse flag and jogger forward flag are set to "0" (step S547), and the value of the jogging memory is put in the jogger counter (step S548). If the value of the jogger counter and the value of the jogging memory are not equal in the check of step S546, the value of the jogger counter is further compared with the value of the jogging memory (step S549), and the value of the jogger counter is compared. If it is larger than the value of, the jogger reverse flag is set to "1" and the jogger forward flag is set to "0" (step S550), and the jogger counter is decremented according to the jogger drive pulse (step S). If the value of the jogger counter is not larger than the value of the jogging memory in the check in step S549, the jogger reverse flag is set to "0" and the jogger forward flag is set to "1" (step S552), and the jogger is set. The jogger counter is incremented according to the driving pulse (step S553).

The seed size data of step S543 is the data transmitted to the RDH 9 side by the copier body 3 from the data detected by the finisher 11 transmitted to the copier body 3 side. Regarding the detection of the sheet size data, a sensor having the same shape as the original size detection in the registration detection unit of the RDH 9 may be provided in the RDH paper ejection sensor unit.

8.12 Jogging Processing of Original Document The jogger fence 231 set in 8.11 performs the jogging operation with reference to the time point when the jogger fence 231 passes through the paper discharge sensor. At the same time, the pulling roller 235 also comes into contact with the original in the direction of pulling the discharged original. The specific processing procedure is shown in the flow charts of FIGS. 95 and 96.

In this process, first, the document acceptance OK flag is checked (step S561), and if the document acceptance is OK, the fall of the document ejection sensor is checked (step S562). Then, as also shown in the timing chart of FIG. 97, the 0.1 second timer and the 0.3 second timer are started under the condition that the document discharge sensor falls (step S563), and the offset roller solenoid 239 is turned ON. Then, the approach roller 235 is lowered (step S564), the jogging flag is set to "1" (step S565), 1 is added to the document number data (step S566), and the data is transmitted to the copying machine main body 3 side.

In the processing of FIG. 96, the jogging flag is checked (step S571), and if the jogging flag is “1”, the 0.25 second timer counts as shown in the timing chart of FIG. It is checked whether it is up (step S572), and if it is up, the 0.1 second timer and the 0.25 second timer are stopped and cleared (step S573), and the jogging flag is set to "0". (Step S574) The jogging is ended, the approach roller solenoid 239 is turned off (step S575), and the approach roller 235 is pulled up and separated from the original.

On the other hand, if the 0.25 second timer is not counted up in step S572, it is checked whether or not the 0.1 second timer is counted up (step S576). If it is counted up, the copying machine main body 3 The jogging data on the data table is selected from the size data transmitted from the side for jogging (step S577), and the jogging data is stored in the jogging memory (step S578). Then, the value of the jogger counter and the value of the jogging memory are compared (step S579). If they are not equal, the value of the jogger counter and the value of the jogging memory are further compared (step S580). In this check, when the value of the jogging counter is larger than the value of the jogging memory, the jogger reverse flag is set to "1" and the jogger forward flag is set to "0" (step S58 1). The jogger counter is subtracted (step S582).

If the jogger counter is not larger than the jogging memory in the check of step S580, the jogger reverse flag is set to “0” and the jogger forward flag is set to “1” (step S583) to match the jogger drive pulse. The jogger counter is incremented (step S584).

8.13 Document Feeding Process from Document Feeding Device to Finisher When the document is returned from the RDH 9 to the finisher 11, the process is performed according to the procedure shown in the flowcharts of FIGS. 98 and 99. In this process, first, it is checked whether the mode reception data is "2" (step S591), and if it is "2", it is checked whether the original document discharge flag is "1" (step S592). If it is "1", the feeding flag is checked (step S593), and if the feeding flag is "1", the count-up of the timer 1 indicating the ON time of the sheet feeding clutch is checked ( Step S594). If the timer 1 counts up in this check, the paper feed clutch is turned off (step S595), and this time it is checked whether the timer 2 indicating the repeat timing is counting up (step S596). If the timer 1 has not counted up in step S594, step S595 is skipped and the process of step S596 is executed.

If the timer 2 is counted up in the check in step S596, the timer 1 and the timer 2 are cleared and stopped (step S597), and 1 is added to the document number data (step S598). Then, the number-of-documents data is transmitted to the copying machine main body 3 side (step S599), and the ON / OFF of the document set detection sensor is checked (step S600). If the document set detection sensor is ON in this check, timer 1 and timer 2 are started (step S601) and the process returns, and if the check in step S600 is OFF, the process directly returns.

If the feeding flag is not “1” in the check of step S593, the feeding / discharging motor and the turn roller are turned on (step S602), and the paper feed clutch is turned on (step S603). After sending and setting the feeding flag to "1" (step S604), the timer 1 and the timer 2 are started (step S601).

On the other hand, when the document discharge flag is not “1” in step S592, ON / OFF3 of the paper feed / discharge motor is checked (step S605). Then, the seventh switching pawl solenoid is turned off and the fifth switching pawl solenoid is turned on to enable the document to be ejected (step S609), and the document number data is set to "0". If the paper feeding / discharging motor is turned on in the check in step S605, the feeding / discharging motor and the turn roller motor are turned off (step S606), the feeding flag is set to "0" (step S607), and the shift roller solenoid is moved. 239 and the fifth switching pawl solenoid are turned off.

8.14 Preprocessing of Document Feeding from Finisher to Document Feeding Device When a document is fed from the finisher 11 to the RDH 9, it is processed according to the flowchart of FIG. That is, since the original cannot be accepted unless the RDH original acceptance flag is "1" (step S611), when the original acceptance flag is "1", the acceptance OK flag is checked to see if the original can be accepted (step S613). If the acceptance OK flag is "1", it means that the original can be accepted, so the document is awaited as it is. If the acceptance OK flag is not "1", the acceptance ready flag is checked (step S613). If the acceptance ready flag is "1", the preparation for accepting the original is completed, and the process returns. If it is not "1", the acceptance ready flag is set to "1" (step S614, the fifth switching claw solenoid and the sixth switching claw solenoid are turned on to open the document transport path from the finisher 11 side. (Step S615), the approach roller solenoid 239 is turned off to move the approach roller 235 away from the original setting table 217 side (step S616), and the jogger home return flag is set to "1" (step S617).

8.15 Document Feeding Process from Finisher to Document Feeding Device When the pre-processing of 8.14 is completed, the motor is turned on and the document can be carried in. The treatment procedure at this time is shown in the flowcharts of FIGS. 101 and 102.

In this process, first, when the RDH original acceptance flag is received (step S621), the jogger home return flag is checked (step S622). If the jogger home return flag is "1", the jogger fence 231 is set to return to the home position, so return. If it is not "1", then the feed / discharge motor and turn roller are turned. It is checked whether the motor is on (step S623). If it is ON, the process returns. If it is not ON, the feed / discharge motor, turn rotor motor, and discharge clutch are turned on (step S624), and the acceptance OK flag is set to "1" (step S625). The document number data is cleared (step S626), the acceptance ready flag is cleared (step S627), and the process returns.

When the RDH original acceptance flag “0” indicating the acceptance end is received from the copying machine main body 3 side, the motor is stopped and the acceptance ends. Specifically, as shown in the flow chart of FIG. 102, this process checks the RDH original acceptance flag (step S631), and if it is not "1", further checks the acceptance OK flag (step S632). If the acceptance OK flag is "1" in the check in step S632, it is set to "0" (step S633), and the feeding / discharging motor, the turn roller motor and the discharging clutch are turned off (step S634).

9. Control Regarding Finisher 9.1 Initial Processing FIG. 103 shows the processing procedure of the initial processing of the finisher 11. In this process, first, in step S641, a subroutine for clearing each port, RAM contents, flags, and counters to initialize them is executed. Next, the finisher connection flag is set to "1" (step S642), and transmission / reception is performed with the copying machine main body 3 side (step S643). Then, the bin home request flag is set to "1" to return the bin 37 to the home position (step S644), and the initial process is executed (step S645).

Note that the initial processing in step S645 is a stapler end flag that becomes “1” when the stapler end, a stapler door open flag that becomes “1” when the stapler door is open, and a “1” when the finisher door is open. Finisher door open flag, “1” when there is paper in the original transport path, original jam flag, “1” when there is paper in the transfer paper transport path, “1” when there is paper in the staple tray Staple tray remaining paper flag is set to 20 when there is remaining paper in the 20 bin Sort bin jam flag, and when moving the jogger fence to the home position, the jogger home return flag is set to "0" This is the process of initializing to.

9.2 Motor ON Processing As shown in the flowchart of FIG. 104, this processing checks whether or not the motor ON flag is “1” (step S651), and if it is not “1”, the finisher The motor provided in 11 is turned off (step S652), and if it is "1", the motor is turned on (step S653).

In addition to the processing of FIG. 104, the motor ON processing includes the processing shown in the flowchart of FIG. 105. In this process, first, it is checked whether the document return flag is "1" (step S661), and if it is "1", the motor is rotated in the paper discharge direction (step S662). If it is not "1", the document feeding flag is checked (step S663). If it is "1", the motor is rotated in the paper feeding direction (step S664). If it is not "1", the motor is turned on. It is turned off (step S665). The motor is controlled to have a linear velocity equivalent to that on the copying machine main body 3 side when the transfer sheet is conveyed, and to a linear velocity equal to that on the RDH 9 side when the document is conveyed.

9.3 Jogger Home Return Process The jogger fence 61 provided on the staple tray 55 is basically controlled in the same manner as the jogger fence 231 provided on the original setting table 217 of the RDH 9. The specific processing procedure is shown in the flowchart of FIG. In this process, first, the jogger home return flag is checked (step S671). If the jogger home return flag is "1" in this check, the jogger fence 185 is in the state of returning to the home position position, so this time, the jogger home position sensor 215 configured by the photo interrupter is set to "H". "Check if the level is reached (step S672). If it is not at "H" level, it means that the jogger fence 185 has not returned to the detection position of the jogger home position sensor 215, that is, the home position, so that the jogger reverse flag is set to "0" in step S673. , The jogger forward flag is set to "1", and the rising signal of the jogger home position sensor 215 is confirmed in step S674. It is driven (step S675), the jogger reverse flag is set to "0" (step S676), and the home position is returned.

On the other hand, when the jogger home position sensor 215 is at the “H” level in the check in step S672, the jogger fence 185 has returned to the home position, so the jogger reverse flag is set to “0” and the jogger reverse flag is set to “0”. Set the forward flag to "1" (step S677), check the fall signal of the jogger home position sensor 215 (step S678), and if the detection signal of the jogger home position sensor 215 falls, set the jogger forward flag to " The jogger counter is reset to 0 "(step S679), the jogger counter is reset (step S680), and the jogger home return flag is set to" 0 "(step S681).

Regarding the relationship between the jogger fence 185 and the jogger home position sensor 215, the home position of the jogger fence 185 is the moment the jogger fence 185 leaves the home position sensor 215. Document jogging is controlled by the values in the jogger counter and jogging memory. Further, as described above, the jogger fence 185 includes the forward jogger fence 185f and the backward jogger fence 185b, but since both have the same operation and processing method, the reference numeral 185 generally indicates both. It was shown to.

9.4 Jogger Fence Standby Process This process is a process of setting the jogger fence 185 at the position of the sheet size + α and waiting for sheet discharge. Specifically, the processing is performed according to the flow charts shown in FIGS. 107 and 108.

In this process, it is confirmed that the jogging flag is not “1” and the jogging state is not set (step S691). If the mode reception data is 6 (step S692), the sort mode flag and the stack mode flag are set. , And the tray mode flag to “0” and the staple pull mode flag to “1” (step S693). If there is seed size data (step S694), the position of the jogger fence 185 can be set. Therefore, the jogging data is selected from the sheet size data and the data table (step S695), and the jogging data is stored in the jogging memory (step S695). In step S696), the jogger counter value is compared with the jogging memory value (step S697). If they are equal, the jogger reverse flag and jogger forward flag are set to "0" (step S689), and the value of the jogging memory is put in the jogger counter (step S699).

On the other hand, if the value of the jogger counter and the value of the jogging memory are not equal in the check in step S697, the value of the jogger counter is further compared with the value of the jogging memory (step S700). If the value of the jogger counter is larger than the value of the jogging memory, the jogger reverse flag is set to "1" and the jogger forward flag is set to "0" (step S701), and the jogger drive pulse is set. The jogger counter is subtracted (step S702). If the value of the jogger counter is not greater than the value of the jogging memory in step S700, the jogger reverse flag is set to "0" and the jogger forward flag is set to "1" (step S703). The jogger counter is incremented according to the driving pulse (step S704).

9.5 Jogging Processing on Staple Tray This processing is processing of moving the jogger fence waiting at 9.4 to the sheet size and moving the transfer paper to the bin fence 123 side by the aligning roller to perform alignment. Is. Specifically, it is performed according to the procedure shown in the flowcharts of FIGS. 109 to 111.

In this process, first, it is checked whether the mode reception data is 6 (step S711). Then, it is confirmed that it is 6, and the trailing edge of the sheet ejection sensor is checked (step S712). If it is trailing, it indicates that the transfer sheet is ejected. Step S713), 0. The 1-second timer and the 0.25-second timer are started (step S714). The timing at this time is similar to the timing chart of FIG.

When the timer is started in step S714, the jogging flag is set to "1" and the jog state is set (step S715), the sheet discharge flag is set to "1", and the transfer paper is discharged (step S716). After sending the flag to the side (step S717), the sheet discharge flag is set to "0" to stop the discharge of the transfer sheet (step S718), the stopper solenoid 195 is turned off, and the bin fence 123 is set up to discharge the discharged sheet. The paper is held on the staple tray 55 (step S719). If the sheet discharge sensor is not lowered in the check in step S712, the discharge of the transfer sheet is not completed, so the stopper solenoid is turned off (step S719) and the bin fence 123 is set up.

When the transfer paper is placed on the staple tray 55 in this way, the staple flag is checked this time (step S721). If the stapling flag is "1", stapling is being executed and therefore the process returns. If the stapling flag is "0", it is checked whether the jogging flag is "1" (step S722). ). If the jogging flag is not "1" in this check, it means that the condition is not jogging, so return and if it is "1". It is checked whether or not the 025 second timer that sets the OFF timing of the approach roller solenoid 195 and the return start timing of the jogger fence 185 is counted up (step S723). If it counts up in this check, it means that jogging has ended, so the closing roller solenoid 195 is turned on, and the 0.1 second timer that sets the timing for starting the operation of the jogger fence 185 in the forward direction, and The 0.25 second timers are stopped and cleared (step S724), the jogging flag is set to "0" (step S725), and the closing roller solenoid is turned off (step S726). On the other hand, if it is determined in step S723 that the 0.25 second timer has not counted up, the 0.1 second timer is counted up (step S727). If not, the jogger fence 185 moves forward. Since it has not moved yet, if the count is counted up, jogging data is selected from the data table by the sheet size data to perform jogging (step S728), and the jogging data is stored in the jogging memory (step S728). P. S729). After that, the value of the jogging counter and the value of the jogging memory are compared (step S730). If they are equal, jogging is completed, and the process returns. S731). If the value of the jogger counter is larger than the value in the jogging memory as a result of this comparison, the jogger reverse flag is set to "1" and the jogger forward flag is set to "0" (step S732). Subtract (step S733) and return. If the value of the jogger counter is not greater than the value of the jogging memory in step S731, the jogger reverse flag is set to "0" and the jogger forward flag is set to "1" (step S734), and the jogger drive pulse is synchronized with the jogger drive pulse. The counter is incremented (step S735) and the process returns.

9.6 Staple Processing When the jogging processing is completed in 9.5, the transfer paper is ready to be stapled by the stapler. This stapling process is performed by the following procedure.

The transfer sheet is moved to the staple position by the jogger fence 185.

-Turn on the staple motor to execute the staple operation.

When the stapling is completed, the stopper solenoid is turned off, the discharge roller 203 is rotated, and the stapled transfer paper is discharged to the stack tray 57.

When the transfer paper is discharged to the stack tray 57, the “copy drop OK flag” is transmitted to the copying machine main body 3 side to indicate the end of the job.

This processing procedure is concretely shown in the flowcharts of FIGS. 112 to 114. In this process, first, the staple flag is checked (step S741), and if the staple flag is not "1", the staple-execution flag is set to "0" (step S742) and the process returns and is "1". For example, it is checked whether the staple motor is ON (step S743). If it is not ON in this check, stapling is not being executed, so it is checked whether the stapling flag is "1" (step S744). If it is not "1", the timer starts for 3 seconds. It is checked whether or not (step S745). If the 3-second timer is not started in this check, the jogging data is selected from the sheet size data by referring to the data table and the stapled state is set (step S746), and the jogging data is stored in the jogging memory (step S747). ) Then, the staple execution flag is set to "1" (step S748). Then, it is checked whether or not the value of the jogging counter and the value of the jogging memory are equal (step S749). If they are equal, jogging has ended, so the jogger reverse flag and jogger forward flag are set to "0". (Step S750), the staple motor and the shift roller solenoid 201 are turned on (step S751), and stapling is executed.

After executing the processing of step S751, it is checked whether or not the staple motor home position sensor is ON (step S752). If it is ON, the staple motor is turned off (step S753), and the stopper solenoid 195 is turned on. Is turned on (step S754) to raise the bin fence 63, the discharge roller clutch is turned on (step S755), the discharge roller 203 is driven, and the 3-second timer for jam check is started (step S756). ) Return. Further, if the staple motor home position sensor is not ON in step S752, the process directly returns.

On the other hand, if the values of the jogger counter and the jogging memory are not equal in the check of step S749, the value of the jogger counter is compared with the value of the jogging memory in step S757, and the value of the jogging memory is more than the value of the jogger counter. If it is larger, the jogger reverse flag is set to "0" and the jogger forward flag is set to "1" (step S758), the jogger counter is added according to the jogger drive pulse (step S759), and the process returns. If the value of the jogger memory of the check in step S757 is not larger than the value of the jogger memory, set the jogger reverse flag to "1" and the jogger forward flag to "0" (step S760), and drive the jogger. The jogger counter is decremented according to the pulse (step S761), and the process returns.

If the 3-second timer is started in step S745, ON / OFF of the sheet discharge sensor is checked (step S762). If it is ON, whether or not there is a transfer sheet on the staple tray 55, that is, Confirm that there is no jammed transfer paper (step S763). If it is not jammed, the copy drop OK flag is set to "1" (step S764), the stopper solenoid 195 is turned on to lower the binfence 123 (step S765), the discharge (half-month) roller clutch is disengaged, and the approach roller solenoid 201 Is turned off (step S766), the 3-second timer is stopped and cleared (step S767), and the process returns. When the ejection roller 203 is stopped in step S766, the ejection roller 203 is stopped at a position where the flat portion 211 of the ejection roller 203 is parallel to the bottom plate 187 of the staple tray 55. Although not shown, a home position sensor for the discharge roller is provided to detect this parallel position.

9.7 Transport Path Switching Processing In this processing, the finisher 11 switches the transport path according to the mode data transmitted from the copying machine main body 3 side, and transfers the transfer paper (sort, stack) to the bin 37 and copy. It is stored in either the (proof) tray 39 or the staple tray 55. Specifically, the processing is as shown in the flowcharts of FIGS. 115 and 116.

In this processing, first, the mode reception data is checked (step S771). The mode reception data is transmitted from the copying machine main body 3 side to the finisher 11 side with the following code.

Copier finisher (mode received data) 000 Dummy data 001 Sort 010 Stack 011 Copy (proof) tray 100 Staple tray 101 Original feeding mode (finisher to RDH) 110 Original feeding mode (RDH to finisher) 111 Not used Therefore, if the mode reception data is "0" in the check in step S771, it is dummy data and the process returns. If it is not "0", it is checked in step S772 whether the mode reception data is "1". If it is "1" in this check, it means that the mode is the sorting mode, so that the solenoid for driving the ninth switching claw 397 is turned on, and the solenoid for driving the tenth switching claw 401 is turned off (step S773). The conveyance path 47 and the sheet conveyance path 135 are opened and conveyed to the bin 37 side as shown in FIG. 32, and the sort mode flag is set to “1”, the stack mode flag, the (copy) tray mode flag, and the staple mode flag are set. The respective values are set to "0" (step S774) and the process returns.

If the mode reception data is not “1” in the check in step S772, it is checked in step S775 whether the mode reception data is “2”. If this check is "2", it means the stack mode, so the solenoid that drives the ninth switching pawl 397 is turned on, and the solenoid that drives the tenth switching pawl 401 is turned off (step S776). 32, the transfer paper transport path 47 and the sheet transport path 135 are opened and transported to the bin 37 side as shown in FIG. 32, the sort mode flag is “0”, the stack mode flag is “1”, and the (copy) tray mode is set. The flag and staple mode flag are each set to "0" (step S777) and the process returns.

If the mode reception data is not "2" in step S775, it is further checked in step S778 whether the mode reception data is "3". If "3", the copy (proof) tray mode is set, so the solenoids for driving the ninth and tenth switching claws 397 and 401 are turned off (step S779), and the second transfer is performed as shown in FIG. The paper transport path 49 is opened to transport the transfer paper to the copy tray 55 side, and the sort mode flag, stack mode flag, staple mode flag are set to “0”, and the (copy) tray mode flag is set to “1” (step S780) Return.

If the mode reception data is not "3" in the check of step S778, it is checked in step S781 whether the mode reception data is "4". If it is not "4", the process returns and if it is "4". Since the mode is the staple mode, the solenoid for driving the ninth switching claw 397 is turned off, the solenoid for driving the tenth switching claw 401 is turned ON, and the second and third transfer sheet conveying paths are set as shown in FIG. The transfer sheets are conveyed to the staple tray 55 side by opening 49 and 51 (step S782), and the sort mode flag, the stack mode flag, and the (copy) tray mode flag are set to "0", and the staple mode flag is set to "1". Set (step S783) and return.

9.8 Operation of Bin The bin 37 moves up and down by using the helical wheel 137 as described above. The control of this operation is basically the same as that of a conventional sorter using a helical cam. That is, in the sort mode, the bin 37 is moved up / down by the bin up flag and the bin down flag each time a sheet is discharged. In the stack mode, the bin position data transmitted from the copying machine body 3 side is compared with the bin counter value to determine whether the bin 37 is up or down. Specifically, the procedure is as shown in the flowchart of FIG. 117.

In this operation, if the bin is in the sort mode (step S791), the bin home request flag is not “1” (step S792), and the sheet is ejected (step S793), the bin is set. It is checked whether the count value of the counter is "1" (step S794). If the count value is not "1", it is checked whether the bin counter and the bin position data are equal (step S795). Then, if the value of the bin counter and the bin position data are equal, it is checked whether or not the bin rising flag is set to "1" and the bin 37 is set to rise (step S796), and the bin is raised. If so, the bin up flag and the bin down flag are both set to "0" to stop the bin 37 (step S797). If not, the bin up flag is set to "0" and the bin down flag is set to "1". ", The bin is lowered (step S798), and the process returns. If the value of the bin counter is not equal to the bin position data in step S795, the bin 37 has not moved to the predetermined position, and therefore the routine returns to continue the operation.

On the other hand, if the value of the bin counter is “1” in step S794, the bin down / down flag is further checked (step S799), and if it is “1” and the bin 37 is in the down / down state, step The process of S797 is executed to stop the bin 37, and if it is not "1", the bin up flag is set to "1" and the bin down flag is set to "0" (step S800), and the bin is in the up state. And return. In addition, in the process of step S793, a delay time after sheet discharge may be provided.

9.9 Process of Transporting Document from Finisher Side to RDH This process is a process of transporting a document from the finisher 11 side to the RDH 9 side in response to data reception from the copier body 3 side. Is performed by the procedure shown in the flow charts of FIGS. 118 to 123.

In this process, first, as shown in FIGS. 118 to 120, when data is received from the copying machine main body 3 side (step S801), the mode reception data is “5” as shown in 9.7. Alternatively, it is confirmed whether it is "6" (step S802). If it is "5" or "6", it is checked whether the value of the bin counter and the value of the bin position data are equal (step S803), and if they are equal, it is confirmed whether the mode reception data is "5" ( Step S804). If it is not "5", both the bin up flag and the bin down flag are set to "0" (step S805), and the contents of the bin counter are transmitted to the copying machine body 3 side (step S806). If the mode reception data is "5", it is checked whether the timer 1 for setting the delay time of the bin stopper solenoid 195 has started (step S807). If it has not started, the bin stopper solenoid 195 is turned on. Then, the bin fence 63 is tilted (step S808), the timer 1 is started (step S809), both the bin up flag and the bin down flag are set to "0", and the movement of the bin is stopped (step S810).

Next, it is checked whether or not the timer 1 is counting up (step S811), and if it is counting up, the bin rising flag is set to “1” to put the bin 37 in a rising state (step S812). Further, it is checked whether or not it has increased by 1/2 bin (step S813). If 1/2 bin has not risen in this check, return is made. If it has risen, the bin rise flag is set to "0" (step S814) to stop raising bin 37 and set the bin feed flag. Set to "1" to feed the original on the bin 37 (step S815), send the contents of the bin counter to the copying machine main body 3 side (step S816), and then stop and clear timer 1 (step S815). (Step S817). When the timer 1 is not counting up at step S811, and when it is not increasing by 1/2 bin at step S813, the process returns as it is. If the timer 1 is not started in step S807, the process skips to step S811 and the subsequent processes are executed.

On the other hand, when the value of the bin counter and the value of the bin position data are not equal in step S803, the retraction solenoid 93 is turned on (step S818), the pick-up roller 73 is retracted, and the paper is fed onto the bin. It is checked whether the flag is "1" (step S819). If it is not "1", the value of the bin counter is compared with the bin position data (step S820). If the value of the bin counter is large, the bin up flag is set to "0" and the bin down flag is set to "1". (Step S821) If not large, the bin rising flag is set to "1" and the bin falling flag is set to "0", and the process returns. If the bin feeding flag is "1" in the check of step S819, the bin feeding flag is set to "0" (step S823), and the bin home request flag is set to "1". The bin 37 is set to return to the home position (step S824), and the process returns.

If the mode reception data is “5” (step S831), the bin top paper feed flag is checked (step S832) as shown in the flowchart of FIG. 121, and the bin top paper feed flag is set. If it is not "1", the process returns, and if it is "1", it is further checked whether there is a sheet on the bin (step S833). If there is a sheet, the original set flag is set to "1" (step S834), and if there is no sheet, the original set flag is set to "0" (step S835), and the original set flag is set to the copying machine main body 3 side. (Step S836) and returns. If the mode reception data is not 5 in the check in step S831, the bin feed flag is checked (step S837). If it is not "1", the process returns and if it is "1", the bin feed flag is returned. Is set to "0" (step S838), the bin home request flag is set to "1" (step S839), and the process returns.

The original set in this manner is conveyed according to the processing procedure shown in the flowcharts of FIGS. 122 and 123. That is, first, the original feeding flag is checked (step S841), and if the original is fed, the mode receiving mode is confirmed (step S542). In this check, if the mode received data is 5 and the document is in the mode to be conveyed from the finisher 11 to the RDH 9, the paper feeding flag is checked (step S843). If the paper is being fed, the timer 1 counts up. It is checked whether or not (step S844). The time set by the timer 1 is the time during which the pickup solenoid 81 is turned on, as can be seen from the timing chart of FIG. If the timer 1 is counting up in step S844, the pickup solenoid 81 is turned off (step S845), and it is checked whether the timer 2 is counting up (step S846). If it is not counted up at step S844, step S845 is skipped and the count-up of timer 2 is checked (step S846). The timer 2 is a timer for setting the time for turning on the paper feeding clutch that controls the driving of the paper feeding / discharging roller 83. If the timer 2 counts up in step S846, the paper feed clutch is turned on (step S847), and the count-up of the timer 3 is checked (step S848). If the timer 2 has not counted up in step S846, step S847 is skipped and the process of step S848 is executed. The time set by the timer 3 is the timing at which the paper feed clutch is disengaged.

If the timer 3 counts up in the check in step S848, the paper feed clutch is disengaged (step S849), and the count-up of the timer 4 is checked (step S850). If the timer 3 is not counted up in the check of step S848, step S849 is skipped and the count-up of timer 4 is checked (step S850). The timer 4 is a timer for setting repeat timing. Therefore, if the timer 4 does not count up in step S850, the process returns. If the timer 4 counts up, the timers 1, 2, 3 and 4 are stopped and cleared (step S851), and 1 is added to the document number data ( In step S852), a document set flag indicating whether or not a document is set on the bin 37 is checked (step S853). If the original set flag is not "1" by this check, no original is set on the bin 37, so the number of sheets data and the original set flag are transmitted to the copying machine main body 3 side (step S854), and are being fed. The flag is set to "0" (step S855), the retraction solenoid 93 is turned on to retract the pickup roller 73 (step S856).

On the other hand, if the paper feeding flag is not “1” in step S843, the document set flag is checked (step S857), and if the document is not set, the process proceeds to step S854. Perform the following processing. If the original is set, the retracting solenoid 93 is turned off to move the pickup roller 73 onto the original of the bin 37 (step S858), and the pickup solenoid 81 is turned off to separate the pickup roller 73 from the original. It is held at the position (step S859), and the feeding flag is set to "1" (step S860). Then, "0" is set to the document number data (step S861), the timers 1 and 3 and the timers 2 and 4 are started (step S862), the pickup solenoid 81 is turned on and the pickup roller 73 is set to the document. Press and contact (step S863) and return. The document can be fed by the operation in step S863.

If it is determined in step S853 that the document is set, the process skips to step S862 and the subsequent processes are executed.

9.10 Processing of Ejecting Original Document from RDH Side to Finisher Side This processing is to eject the original document discharged from the RDH 9 side onto the bin 37. Specifically, FIGS. It is performed according to the procedure shown in the flow chart.

In this process, the mode reception data is checked (step S871). If the mode reception data is 6, the original is discharged from the RDH 9 side to the finisher 11 side. It is checked whether the values of the position data are equal (step S872), and if they are equal, the document return OK flag is checked (step S873). If the original return OK flag is "1" in this check and the original is ejected, then the trailing edge of the bin ejection sensor is checked (step S874). The timer 2 is started (step S875), 1 is added to the document number data (step S876), and the number data and the document return OK flag are transmitted to the copying machine main body 3 side. If the original return OK flag is not 1 in the check in step S873, the pickup solenoid 81 is turned off (step S878), the retraction solenoid is turned off (step S879), and the original return OK flag is set to "1" (step S879). (S880) After the original number data is cleared (step S881), the number data and the original return OK flag are transmitted to the copying machine main body 3 side.

The timing set by the timer 1 is the timing at which the pick-up solenoid 81 is turned on after the passage of the sheet is detected by the bin discharge sensor as shown in the timing chart of FIG. The timing set by 2 is the timing while the pickup solenoid 81 is ON.

After ejecting as described above, the originals on the ejected bins 37 are aligned. In this processing, as shown in the flowchart of FIG. 126, the timer 2 is started (step S891), it is confirmed that the timer 1 has counted up (step S892), the pickup solenoid 81 is turned on (step S893), and the document is read. When the time is set to the side of the bin fence 123 and the preset time of the timer 2 has passed (step S894), the pickup solenoid 81 is turned off (step S895), and the timer 1 and the timer 2 are stopped and cleared (step S896). .

When performing this process, as shown in the flowchart of FIG. 127, the original document return flag is checked (step S901), and when the original has not been ejected, the mode reception data is checked. However, if the mode reception data is not "5" or "6" (step S902), it is not the mode in which the pickup roller 73 is used. Therefore, the retract solenoid 93 is turned on to move the pickup roller 73 from the bin 37 to the other side. Evacuate.

When the document is conveyed from the finisher 11 to the RDH 9, size detection and document reversal are performed. The size is detected by a sensor provided at an arbitrary position in the transport path from the finisher 11 to the RDH 9 according to the flowchart of FIG. 91 described in the above section 8.9. The document inversion is performed as described in the section 2.2, 9.2 with reference to FIGS. 17, 18 and 19.

[Effect of the device]

 As is apparent from the above description, according to the idea of claim 1 configured as described above, when picking up a document before exposure, the stopper means is tilted, and the upper surface of the tilted stopper means and the original document are picked up. When the original placing and sorting means is moved so that the original is pulled out and the exposed original is ejected so that the level at which the feeding means receives the original is almost the same level, the original before exposure is not stored. The original placement and sorting means can be lowered below the original pull-out position, and the upper end of the standing stopper means can be stopped at a position where it is lower than the level at which the originals are discharged from the original discharge means to discharge and sort the originals. , The structure for simplifying the structure becomes unnecessary because the mechanism for distinguishing the unexposed original document from the exposed original document is not required. Further, since the unexposed original document and the exposed original document can be distinguished only by controlling the movement stop position of the original document placement and sorting means so that the paper feeding position and the paper ejecting position are different, the control is also simplified.
