The punching mode means that one end of the sheet is punched by the punching unit 40.

As described above, the CPU determines whether or not the digital copying machine 1A can be set by the selection with the manual switch. As shown in Table 2 below, the ROM of the control unit 950 stores a table indicating combinations that cannot be set in the digital copying machine 1A, and the RAM is set at the time of initial setting.
Has been deployed to. Table 2 exemplifies combinations that cannot be set.

[0052]

[Table 2]

The CPU has a paper feed controller 909 and a controller 1.
It is determined whether or not the selection of the manual switch notified from 49 corresponds to the unsettable combination illustrated in Table 2. For example, in the selection of the first-stage manual switch in Table 2, both the edge-stitched sheet / non-stitched sheet discharge tray selection switch 936 and the saddle stitch + folding processing sheet discharge tray selection switch 937 are selected (depressed). Three
It is unknown whether the sheet is discharged to the lifting tray 90 side or the folded sheet bundle discharging stacker 80 side shown in FIG. Also,
In the selection of the second-stage manual switch in Table 2, both the A5 size sheet cassette selection switch 930 and the A4 size sheet cassette selection switch 931 are selected, so that the sheets stored in the A5 size cassette 910 shown in FIG. 1 are supplied. Paper or A4 size cassette 911
It is unclear whether to feed the sheets stored in. Furthermore, the selection in the third row of Table 2 is input from the touch panel 248 shown in FIG.
As shown in, the setting is incorrect because the booklet becomes a long and narrow booklet and its use cannot be found. Note that in the selection shown in the third row, the CPU instructs sheet feeding to the cassette capable of performing the horizontal feeding illustrated in FIG. 4B and also causes the image forming unit 902 to display the image corresponding to the horizontal feeding. This is an example of an improper setting that occurs when an input is made from the touch panel 248 because it is formed.

The case in which the CPU determines whether or not it corresponds to an unsettable item will be described with reference to the example shown in the second stage. A5 size sheet cassette selection switch 930 and A4 size sheet cassette selection switch When both 931 are selected (pressed), it is determined that they are not settable. That is, the stapler selection switch 9
The audio output control unit 2 does not wait for selection of No. 35 or end-stitched sheet / non-stitched sheet discharge tray selection switch 936.
The warning content shown in Table 2 is issued to 64 via the speaker 184. That is, for example, an operator is warned by voice such as "A5 size or A4 size is unknown. Please set again." As a result, the operator can perform the resetting.

2. The document D is set on the automatic document automatic feeding device 940, and after the operator changes the setting displayed on the touch panel 248 or inputs the unset contents by finger touch, the start button on the touch panel 248 is pressed. Then, the CPU takes in all the setting information of the digital copying machine 1A sent from the touch panel control section 250.

The CPU takes in the image data read by the image input section 200 via the A / D conversion section 960,
It is sequentially stored in the hard disk 961. When an image is read using the automatic document feeder 940, it is possible to determine the end of reading the document D by a signal from an empty sensor (not shown) in the automatic document feeder 940. When the images are read one by one without using the automatic document feeder 940, the operator, for example,
A pressing of an image reading end button such as “#” is requested, and when the button is pressed, it is determined that the reading is completed.

Next, the CPU sends the setting information relating to the sheet post-processing apparatus 2 to the control section 149 of the sheet post-processing apparatus 2 and causes the image forming section 902 to form an image on the sheet according to the image data in the hard disk 961. Let it run.
That is, the CPU outputs a paper feed signal to cause the paper feed device 909 to feed a sheet of a predetermined size. The paper feed control unit 180 rotationally drives the pair of rollers to feed a sheet of a predetermined size from the designated cassette. The skew of the sheet is corrected by the pair of rollers in the sheet feeding device 909, and the sheet is conveyed toward the image forming unit 902 with the timing adjusted. The CPU irradiates the photosensitive drum 914 with the image data of one sheet line by line from the laser unit 922. The photosensitive drum 914 is charged in advance by the primary charger 919, and an electrostatic latent image is formed on the photosensitive drum 914 by the irradiation light. This electrostatic latent image is developed by the developing device 915 and a toner image is formed on the photosensitive drum 914.

In the image forming section 902, the photosensitive drum 914
The toner image of is transferred onto the fed sheet by the transfer charger 916. The sheet onto which the toner image has been transferred is charged with a polarity opposite to that of the transfer electric device 916 by the separation charging device 917 and separated from the photosensitive drum 914. Furthermore,
The separated sheet is conveyed to the fixing device 904 by the endless conveyance belt 920, the transfer image is permanently fixed on the sheet by the fixing device 904, and the image is formed (recorded) on the sheet. In double-sided printing, an image is formed on the other surface of the sheet via the duplex 921. Then, the sheet on which the image is formed is discharged from the digital copying machine main body 1 to the sheet post-processing apparatus 2 side by the discharge roller pair 905.

When the control unit 149 of the sheet post-processing apparatus 2 receives the setting information related to the sheet post-processing apparatus 2 from the CPU of the control unit 950 of the digital copying machine main body 1, the head assembly 31 and the anvil assembly 32 are moved to the initial positions. And waits until the sheet is discharged from the digital copying machine body 1. Hereinafter, the operation of the sheet post-processing apparatus 2 will be described in different cases according to the modes shown in Table 1.

(1) When the setting information of the non-binding processing mode is received from the CPU of the non-binding processing mode control unit 950, the control unit 149 first drives a stepping motor (not shown) to cause the pushing claw 13 to move to the above HP. From the position, the end surface of the push-out claw 13 becomes a sheet stacking reference on the processing tray 8 and is moved to a pre-home position (PreHP position) on the side of the elevating tray 90 by a predetermined distance from just above the pulley shaft 10a and stopped. At this time, the upper conveyance roller 19 is at the separated position, and the stopper 21
Is in the retracted position. The movement from the HP position to the PreHP position can be performed by counting the number of pulses sent to a stepping motor (not shown).

In parallel with this, the driving rollers of the conveying roller pair 5 and the discharging roller pair 6 are rotated to wait until the sheet is discharged from the discharging roller pair 905 of the digital copying machine main body 1. When the sheet is discharged from the digital copying machine main body 1, the sheet is conveyed to the processing tray 8 by the conveying roller pair 5 and the discharging roller pair 6. When the sheet detection sensor 4 detects a sheet, the control unit 149 measures the activation timing of the alignment motor that moves the alignment plate 9 and the paddle motor that rotates the paddle 17.

When the sheet is discharged onto the processing tray 8,
The matching motor and paddle motor are driven. By this drive, the aligning plate 9 moves in the width direction intersecting the sheet conveying direction to align both ends of the sheet, and the paddle 17 aligns the end portion of the sheet with the end surface of the pushing claw 13 which is located at the PreHP position in advance. Rotate to align (match). This operation is repeated every time the sheet is discharged to the processing tray 8.

When a predetermined number of sheets are aligned with the end faces of the pushing claws 13, the conveying motor and the paddle motor are stopped, and a stepping motor (not shown) for moving the endless transfer belt 12 is driven, so that the sheet bundles are bundled at the end faces of the pushing claws 13. While pressing, move to the lifting tray 90 side.
As a result, the sheet bundle is stacked on the elevating tray 90.

When the stack of sheets is loaded on the elevating tray 90, the elevating tray motor (not shown) is rotated to lower the elevating tray 90 by a certain amount, and the elevating tray motor is rotated in reverse, whereby the sheet surface sensor 93 detects the sheet maximum. The elevating tray 90 is raised to a position where the upper surface is detected, and is kept waiting at this position until the next sheet bundle is placed.

Therefore, in the non-post-processing mode in which the binding process is unnecessary, the pushing claws 13 are preliminarily positioned at the PreHP position and the stack of sheets is stacked without moving the sheets to the regulation position of the stopper 21, and the lifting tray 90 side is provided. Since the sheet is pushed out, the sheet post-processing apparatus 2 can follow the sheet discharging speed even if the sheet discharging speed of the digital copying machine main body 1 is high.

(2) When receiving the setting information of the edge-stitching processing mode from the CPU of the edge-stitching processing mode control unit 950, the control unit 149 sets the solenoid (not shown) to the ON state to position the stopper 21 at the regulating position.
The driving rollers of the conveying roller pair 5 and the discharging roller pair 6 are rotated to discharge the sheet discharged from the digital copying machine main body 1 to the processing tray 8 and drive the alignment motor and the paddle motor. Both ends of the sheet in the width direction are aligned by the alignment plates 9, and the ends of the sheet are transferred to the side surfaces of the legs of the stopper 21 and stopped. By repeating this for the specific number of sheets, the sheet bundle is regulated by the stopper 21 and aligned.

Next, after the sheet bundle is aligned with the stopper 21, the upper conveyance roller 19 is moved to the lower conveyance roller 18 side to sandwich (nip) the sheet bundle, and the solenoid (not shown) is turned off to stop the stopper 21. Is moved to the retracted position, and a stepping motor (not shown) is driven a predetermined number of steps in the direction opposite to the non-post-processing mode. By this drive,
The upper conveyance roller 19 and the lower conveyance roller 18 convey the sheet bundle to the stapler unit 30 side while sandwiching the sheet bundle until the binding position of the sheet bundle reaches the head position of the head assembly 31 at the initial position. Incidentally, when the stepping motor (not shown) rotates in the reverse direction in this way, it is performed by interposing a one-way clutch (not shown) between the pulley 10 and the pulley shaft 10a which stretch the endless transfer belt 12, and Drive is not transmitted from a stepping motor (not shown) to the transfer belt 12, and the endless transfer belt 12 and the pushing claw 13 are kept in a stopped state.

Next, the head assembly 31 and the anvil assembly 32 perform binding processing on the end portions of the sheet bundle. When performing the binding process at a plurality of positions at the end of the sheet bundle, the binding process is performed after moving the stapler unit 30.

When the binding process is completed, the lower transport roller 18 and the upper transport roller 1 are driven by a stepping motor (not shown).
9 and the endless transfer belt 12 are driven so as to convey the sheet bundle to the side of the elevating tray 90. By this driving, the conveyance of the sheet bundle after the binding processing is delivered from the lower conveyance roller 18 and the upper conveyance roller 19 to the pushing claw 13. The pushing claw 13 pushes the sheet bundle toward the elevating tray 90, so that the sheet bundle is stacked on the elevating tray 90. Subsequent operations of the elevating tray 90 are the same as those in the non-post-processing mode described above, and a description thereof will be omitted.

(3) When the saddle stitching and folding processing mode setting information is received from the CPU of the saddle stitching and folding processing mode control unit 950, the sheets discharged from the digital copying machine main body 1 are the same as in the edge binding processing mode. It is loaded on the processing tray 8. After the sheet bundle is aligned and stacked on the processing tray 8, the transport upper roller 19 is lowered to the transport lower roller 18 side to sandwich the sheet bundle, and the solenoid (not shown) is turned off to position the stopper 21 at the retracted position. Let

Next, a stepping motor (not shown) is driven in the direction opposite to the non-staple mode to convey the sheet bundle to the stapler unit 30 side while the conveyance upper roller 19 and the conveyance lower roller 18 hold the sheet bundle.

After the sheet bundle is started to be transferred, when the edge detecting sensor 54 detects the leading edge of the sheet bundle in the conveying direction, the control section 149 sets the sheet length information in the setting information received from the digital copying machine main body 1. Based on the above, after the central portion of the sheet conveying direction is conveyed to a position that coincides with the binding position, the driving of the stepping motor (not shown) is stopped, and the binding processing is performed on the central portion of the sheet bundle in the conveying direction (see FIG. ). When binding multiple locations, head assembly 3
1. The binding process is performed after the anvil assembly 32 is moved to a predetermined position in a direction intersecting the sheet conveying direction. In addition,
When the sheet bundle is conveyed to the binding position, the position of the sheet bundle on the leading end side in the conveying direction is a position where the bundle conveying lower roller 52 in the folding unit 50 and the bundle conveying upper roller 51 in the separated state have already passed.

Then, in order to perform the folding process, the upper conveying roller 19 is set to the separated position and the nipping of the sheet bundle is released.
The conveyance motor 162 is driven to rotate the bundle conveyance upper roller 51 and the bundle conveyance lower roller 52 to convey the sheet bundle further downstream. At the time of this conveyance, the control unit 149 determines, based on the detection signal from the edge detection sensor 54 and the sheet length information stored in the RAM, that the central portion in the conveyance direction of the sheet bundle, that is, the binding position is the folding position. The conveyance speed of the sheet bundle is decelerated and stopped. In this state, the leading end portion of the sheet bundle is nip-supported by the nip between the bundle conveying upper roller 51 and the bundle conveying lower roller 52 while hanging down in the sheet bundle passage 58.

Next, the folding rollers 57a and 57b are rotated in the direction in which the sheet bundle is nipped, and the pushing plate 55 is lowered. In synchronization with this fall, backup guide 5
9a and 59b are also moved so as to open the peripheral surface of the folding roller on the sheet bundle side. When the pushing plate 55 descends, the sheet bundle is wound around the folding rollers 57a and 57b, after which the pushing plate 55 moves in a direction away from the sheet bundle, and the sheet bundle is further folded by the folding rollers 57a and 57b (nip). Be transported). The sheet bundle nipped and conveyed by the folding rollers 57a and 57b is fed to the folded sheet bundle discharge stacker 80.
It is discharged to and stocked. At this time, since the folded sheet bundle is pressed by the folded sheet presser 81, the folded sheet bundle (booklet) does not open and does not interfere with the next booklet.

On the other hand, after the folding operation is started, when the thrust plate HP sensor (not shown) detects that the thrust plate 55 has reciprocated a predetermined number of times according to the length of the sheet bundle in the conveying direction, the control unit 149 causes The operation of each part of the folding unit 50 is stopped. When folding the sheet bundle, the veneer 55
When the sheet bundle is pushed into the folding rollers 57a and 57b once and then moved to the pushing position again, the sheet folding timing and the thrust plate of the folding rollers 57a and 57b are prevented so as not to contact both ends of the folded sheet bundle. 5
The movement timing of 5 is set.

(4) When the setting information of the folding processing mode is received from the CPU of the folding processing mode control unit 950, the control unit 149 executes the same processing as the saddle stitching and folding processing mode described above. The difference between the folding processing mode and the saddle stitching or folding processing mode is that the folding unit 50 does not perform the binding processing on the stapler unit 30.
This is a point to execute the folding process. Therefore, the control unit 14
After aligning the end portions of the sheet bundle by the aligning unit 20, the stepping motor (not shown) is driven in the direction opposite to the non-post-processing mode to cause the upper conveyance roller 19 and the lower conveyance roller 18 to sandwich the sheet bundle. In order to convey the sheet bundle to the stapler unit 30 side as it is and perform the folding process, the conveyance upper roller 19 is set to the separated position, and the nipping of the sheet bundle is released. The conveyance motor 162 is driven to rotate the bundle conveyance upper roller 51 and the bundle conveyance lower roller 52, and the sheet bundle is folded in the unit 50.
The sheet is conveyed to the side, and the folding unit 50 performs the folding process as described above, and the sheet bundle that has been subjected to the folding process and not bound is discharged to the folded sheet bundle discharge stacker 80. The head assembly 31 and the anvil assembly 32 are stopped at the initial position.

(5) When the punch processing mode and the setting information of the punch processing mode or the punch and binding processing mode are received from the CPU of the punch and binding processing mode control unit 950, the control unit 1
49 performs the same processing as the non-post-processing mode or the binding processing mode, respectively. Punch processing mode,
Alternatively, the punching and binding processing mode is different from the non-post-processing mode or the binding processing mode in that the punch unit 40 performs punching processing on the leading end of the sheet transported in the transport guide 3 in the transport direction. Hereinafter, the punching process by the punch unit 40 will be described in detail, and the description of the same process as the non-post-processing mode or the binding process mode will be omitted.

When the sheet detection sensor 4 detects the leading edge of the sheet being conveyed by directing the inside of the conveyance guide 3 toward the discharge roller pair 6 side, the controller 149 rotates the conveyance roller pair 5 (conveyance).
The speed is gradually reduced and stopped when the leading end of the sheet is positioned at the punching position of the cylindrical cutter 43. Such position control can be realized, for example, by counting the number of pulses of a stepping motor that rotationally drives the pair of transport rollers 5. Next, the control unit 149 turns on the solenoid (not shown) to turn on the cylindrical cutter 43.
Is inserted through the cutter through hole formed in the transport guide 3. As a result, punch holes are formed at the leading end of the sheet. The position of the cylindrical cutter 43 is detected by a reflection type sensor (not shown), and the output of the reflection type sensor changes from the OFF state to the ON state by inserting the cylindrical cutter 43 into the cutter through hole. The control unit 149 turns off the solenoid (not shown) to retract the cylindrical cutter 43 from the cutter through hole, and after confirming that the output from the reflective sensor is in the off state, the control unit 149 turns the conveying roller pair 5 again. Rotate.
As a result, the sheet having the punched holes is conveyed to the discharge roller pair 6 side.

(Operation etc.) Next, the operation of the digital copying machine 1A of the present embodiment will be described.

As described above, in the digital copying machine 1A of the present embodiment, A5 is set according to the plurality of functions of the auxiliary devices such as the sheet feeding device 909 and the sheet post-processing device 2.
