BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus represented by a copying machine or the like, and more particularly to an image forming apparatus capable of setting a slip sheet mode.

[0002]

[Prior Art] The interleaf sheet is a so-called chapter break sheet, and is for inserting a interleaf sheet for each predetermined chapter to attach chapter breaks. There has been a conventional image forming apparatus having this slip sheet mode. In this conventional apparatus, a position for inserting a slip sheet is set and the position is displayed as it is. That is, in this type, the positions of inserting the slip sheets are displayed in the order of input, and the slip sheet positions can be visually recognized.

[0003]

By the way, in the image forming apparatus having such a slip sheet mode, the positions for inserting the slip sheets are merely displayed in the order of input, and thus the position of the input order is changed. In the case of a display, it is often different from the position where the actual sheet is inserted. Therefore, it is troublesome for the operator to check the slip sheet position, and there is a problem in efficiency. This is a remarkable problem especially when the slip sheet position is added later.

Further, when the quality of the image is taken into consideration, the quality of the recording medium, for example, the quality of the paper may have a great influence on the quality of the image. That is, as the recording medium, for example, plain paper, recycled paper, OHP sheet, thick paper, second original drawing, etc. can be used. However, since the image forming conditions differ depending on these recording media, the operator recognizes the quality of the paper. Otherwise, the image quality may deteriorate depending on the type of recording medium '(quality).

The present invention has been made in view of the circumstances of the prior art as described above, and a first object thereof is to enable input without particularly paying attention to the feeding order of interleaving sheets and the additional position of interleaving sheets. An object of the present invention is to provide an image forming apparatus capable of improving processing efficiency of an operator.

A second object is, in addition to the first object, to provide an image forming apparatus in which optimum image forming conditions can be set according to the quality of a recording medium.

[0007]

The first purpose is to supply an image forming means for forming an image on a recording medium and a saddle stitching recording medium for image formation to the image forming means. Medium supply means, second recording medium supply means for supplying a recording medium for interleaving paper to the image forming means, supply location designation input means for designating interleaving paper supply location, and supply for displaying the designated supply location. The recording medium for the interleaf sheet is secondly placed at the interleaf sheet location designated by the location display means and the interleaf location designation input means.
Sheet feeding control means for feeding the recording medium for saddle stitching from the first recording medium feeding means to a portion other than the interleaf sheet position, and a plurality of interleaving sheet feeding locations are designated. This is achieved by the first means including display control means for rearranging and displaying the designated supply points in the supply order.

The second object is to provide the first means,
Further, it is achieved by the second means including the quality information input means for inputting the quality information of the recording medium and the display means for displaying the quality information input by the quality information input means.

[0009]

In the first means, the interleaf sheet supply location is designated by the supply location designation input means, the designated position is displayed on the supply location display means, and the interleaf sheet is supplied to the location.
Further, when a plurality of interleaf paper supply points are designated, the display positions are rearranged in order by the display means and then displayed in the rearranged order. Thereby, the operator can easily confirm the rearrangement position.

In the second means, if the quality information of the recording medium is input in advance, the quality information can be confirmed when an image is formed on the recording medium. The operator can easily and efficiently obtain an image of a desired quality on the recording medium by automatically or manually setting the image forming condition according to the quality information.

Next, the operation of the copying machine having the above structure will be briefly described. The photoconductor drum 7 is rotatably supported by the drum shaft 33 and rotates counterclockwise in response to a copy command or the like. Simultaneously with the rotation of the photoconductor drum 7, the charge removal lamp 9, the PTC 36, the separation charger 27, and the toner attached to the photoconductor drum 7 and the nonuniform electric potential do not reach the charging charger 6 and the developing unit 37.
The transfer charger 28, the eraser 5, the cleaning unit 12, the bias roller 13, the PCC 25, and the quenching charger 11 are driven. After passing through the cleaning unit 12 and the discharging lamp 9, the surface potential of the photosensitive drum 7 becomes zero.

The photosensitive drum 7 is driven by a main motor (not shown). At this time, the leading edge of the image is a portion after the position where the controller passes the cleaning unit 12.

When the photosensitive drum 7 is rotated to a fixed position, the original placed on the contact glass 4 by the ADF 3 is scanned by the first carriage which is integrated with the first scanning mirror 15, the illumination unit 14 and the like. To be done.

And the registration roller 35 is driven at the timing when the tip of the toner image on the photosensitive drum 7 is aligned.

The toner image on the photosensitive drum 7 is transferred to a transfer paper by the transfer charger 28. At this time, the surface of the photoconductor 7 is very smooth, and the adhesion between the photoconductor drum 7 and the transfer paper is large. Therefore, by lowering the potential of the transfer paper by the separation charger 27, the photoconductor drum 7 and the transfer paper are separated from each other. Release the adhesion of. Next, the transfer paper is separated from the photoconductor drum 7 by the separation claw 26, and the transfer paper thus separated is sent to the fixing unit 18 by the conveyor belt 21. The transfer paper sent to the fixing unit 18 is subjected to heat and pressure on the toner, and the toner image on the transfer paper is fixed on the transfer paper, and then the transfer paper is transferred to the reversing unit 19.
It is discharged to the sorter 20 via. When performing double-sided copying or the like, the sheets are discharged to the double-sided tray 22 via the reversing unit 19.

Since a small amount of toner image remains on the surface of the photosensitive drum 7 after the transfer, the PCC 25 is operated, the surface is cleaned by the cleaning brush and the cleaning blade in the cleaning unit 12, and the next quenching charger is used. The surface potential is made constant by 11 and the discharge lamp 9. These control timings are obtained mainly by a pulse generated in synchronization with the rotation of the photosensitive drum 7 or a reference pulse for driving the photosensitive drum 7.

When -1 is not attached, as shown by the chain double-dashed line, it is in a position where it enters the paper end detection sensor 418 and blocks its optical path, and the bottom plate 411 is pushed up, and the tip end is pushed up by the topmost paper. When it is rotated, it rotates in the right-handed direction, whereby the light blocking plate 416 goes out of the inside of the paper end detection sensor 418 to release the blocking of the optical path.

As a result, the output signal of the paper end detection sensor 418 changes, and the presence or absence of paper in the paper feed cassette 40-1 can be determined by detecting it by the control unit.

A cutout (not shown) is formed in the portion of the bottom plate 411 facing the filler 417, and when the bottom plate 411 rises in a state where no paper is placed, the filler 417 is moved upward by the cutout. Since it is not rotated to, the control unit detects the absence of paper.

The operation and control of the copying machine according to the embodiment constructed as described above will be described.

First, FIG. 13 shows the overall processing procedure in the slip sheet mode of the copying machine in this embodiment. In the slip sheet mode, in this copying machine, the set sheet number input routine is first used to input the set sheet number from the ten keys 202 (step S1), and the slip sheet (chapter break) mode is selected (step S2). Then, the document is set on the ADF (step S3) and the wait state is maintained until the start key 20 is pressed (step S4). Then, the start key is turned on to perform initialization (step S5).

When the initial setting is completed, a document feed signal is transmitted to the ADF, the document is set at a copyable position on the contact glass (step S6), and the copy number counter and the discharged sheet number counter are cleared (step S7). ).
When the counter is cleared, a copying operation is performed to make a copy according to the set number of sheets (steps S8 and 9), and the discharge of the copy made according to the selected interleaving paper mode is controlled (step S10). .. Then, the copy operation and the subsequent steps are repeated until the number of copies reaches the set number (step S11).

When the copying operation is completed, a document feed signal is transmitted to the ADF and the document is ejected from the contact glass (step S12). If there is still an original, the next original is fed and the above-mentioned copying operation is repeated (step S1).
3). If there is no document, wait for completion of paper ejection (step S14) and turn off the conveyance drive motor (step S14).
15). Then, perform post-processing such as stapling,
It ends (step S16).

The subroutine for inputting the number of sets in step S1 is executed in the procedure as shown in the flowchart of FIG. In this processing procedure, it is first checked whether or not the ten key 202 is pressed (step S21). Next, the pressed numeric keypad data is stored in the RAM 302 (step S22), the set number indicator 204 is turned on according to the set RAM data (step S23), and the process returns.

The interleaving mode setting subroutine of step S2 is performed in the procedure shown in FIG. In this process, it is checked whether or not the slip sheet key 225 is pressed (step S31), and if it is not pressed, the process returns, and if it is pressed, the slip sheet mode flag is set (step S32), and then the slip sheet is inserted. The supply position input process is executed (step S33) and the process returns.

The initialization sub-retaining in step S5 is executed in the procedure shown in the flowchart of FIG. In this procedure, first, the document number counter is cleared (step S41), and the conveyance drive motor is turned on (step S42). Next, it is checked whether or not the mode is the sort mode (step S43). If the mode is not the sort mode, the switching claw 46 is lowered so that the sheet is discharged to the paper discharge tray side (step S44). 46 is raised so that the copy is conveyed to the bin side (step S45) and the process returns. A in step S6
The DF document feeding subroutine is executed in the procedure as shown in the flowchart of FIG. In this procedure, ADF
A document feed signal is output to feed the document (step S51), and the document number counter is incremented by 1 (step S52), and the process returns.

The paper feed control subroutine of step S8 is executed in the procedure as shown in the flowchart of FIG. In this process, first, the input slip sheet data is checked to determine whether it is the slip sheet timing (step S
61). If it is the interleaf sheet timing, the interleaf sheet is fed (step S62), and if it is not the interleaf sheet timing, the plain sheet is fed (step S63) and the process returns.

The paper discharge control subroutine of step S10 is executed in the procedure as shown in the flowchart of FIG. In this process, first, it is checked whether or not the mode is the sort mode (step S71). If the mode is not the sort mode, the discharge sensor of the discharge tray is checked (step S77), and when the discharge sensor is turned on, the discharge counter is displayed. Add one (step S78) and return.

If it is the sort mode, the ejection sensor of the bin is checked (step S72), and the ejection sensor is turned on.
Then, the paper discharge counter is incremented by 1 (step S73).
Next, for the next stack operation, the current bin deflecting claw is turned off and the current bin deflecting claw one bin below is turned on (step S74). After this processing is completed, it is checked whether the set number of sheets and the number of ejected sheets are equal (check whether all the copies of one original are ejected) (step S75), and if they are ejected, the next operation is performed. Therefore, the deflecting claw of the current bin is turned off, and the deflecting claw of the leading bin of the block is turned on (step S76), and the process returns.

The post-processing subroutine of step S16 is executed in the procedure shown in the flowchart of FIG. In this process, it is checked whether the staple mode is set (step S81). If the staple mode is set, the staple process is executed for each bin (step S8).
2) Return. If the staple mode is not set, the staple process is not executed and the process returns.

FIG. 21 is a flow chart showing the processing procedure of the slip sheet input processing. In this process, first, step S
The input of the numeric keypad 202 is judged at 91, and if there is an input,
In other words, if pressed, the data is stored in the memory of the chapter currently being input (step S92) and displayed at the display positions 503 to 512 (FIG. 23) of the chapter being input (step S93), and the numeric keypad is pressed. Perform input processing.

When it is determined in step S91 that the numeric keypad is not input, the #key 502 (FIG. 23) is determined to be input (step S94).
It is determined whether or not it is the 0th chapter, that is, the final position for specifying the slip sheet (step S95), and if it is not the 10th chapter, input of the next chapter is started (step S96). On the other hand, if the chapter currently input in step S95 is the final location of the interleaf sheet designation, the interleaf sheet position input is terminated, the interleaf sheet data rearrangement processing is executed (step S98), and the process returns.

If the # key 502 has not been pressed in step S94, it is determined whether the designated end key has been pressed (step S97). If not, the process returns to step S91 and the subsequent processing is executed. If it is pressed, the rearrangement process of step S98 is executed (step S98) and the process returns.

A display example at this time is shown in FIGS. 23 (a) and 23 (b). The subroutine for rearranging the interleaf data in step S98 is executed in the procedure as shown in the flowchart of FIG.

That is, in this process, the interleaf paper supply location data stored for each chapter is temporarily stored in another memory (step S101), the data is sequentially determined, and the data having the smallest value is determined as the first chapter. For the eyes, that is, as the first interleaf data to be supplied, it is stored in the first chapter memory, and the next smaller data is stored in the second chapter memory. In the memory (step S102). Then, when all the data are stored, the stored data is stored in each of the display positions 503-5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus represented by a copying machine or the like, and more particularly to an image forming apparatus capable of setting a slip sheet mode.

[0002]

2. Description of the Related Art A slip sheet is a so-called chapter break sheet, and is for inserting a slip sheet for each predetermined chapter to mark chapter breaks. There is a conventional image forming apparatus having this interleaving paper mode. In this conventional one, the position for inserting interleaving paper is set,
The position is displayed as it is. That is, in this type, the positions of inserting the slip sheets are displayed in the order of input, and the slip sheet positions can be visually recognized.

[0003]

By the way, in the image forming apparatus having such a slip sheet mode, the positions for inserting the slip sheets are merely displayed in the order of input, and thus the position of the input order is changed. In the case of a display, it is often different from the position where the actual sheet is inserted. Therefore, it is troublesome for the operator to check the slip sheet position, and there is a problem in efficiency. This is a remarkable problem especially when the slip sheet position is added later.

Further, when the quality of the image is taken into consideration, the quality of the recording medium, for example, the quality of the paper may have a great influence on the quality of the image. That is, as the recording medium, for example, plain paper, recycled paper, OHP sheet, thick paper, second original drawing, etc. can be used. However, since the image forming conditions differ depending on these recording media, the operator recognizes the quality of the paper. Otherwise, the image quality may deteriorate depending on the type of recording medium '(quality).

The present invention has been made in view of the circumstances of the prior art as described above, and a first object thereof is to enable input without particularly paying attention to the feeding order of interleaving sheets and the additional position of interleaving sheets. An object of the present invention is to provide an image forming apparatus capable of improving processing efficiency of an operator.

A second object is, in addition to the first object, to provide an image forming apparatus in which optimum image forming conditions can be set according to the quality of a recording medium.

[0007]

The first purpose is to supply an image forming means for forming an image on a recording medium and a saddle stitching recording medium for image formation to the image forming means. Medium supply means, second recording medium supply means for supplying a recording medium for interleaving paper to the image forming means, supply location designation input means for designating interleaving paper supply location, and supply for displaying the designated supply location. The recording medium for the interleaf sheet is secondly placed at the interleaf sheet location designated by the location display means and the interleaf location designation input means.
Paper feed control means for supplying the recording medium for saddle stitching from the first recording medium supply means to a position other than the interleaving paper position, and a plurality of interleaving paper supply locations are designated. This is achieved by the first means including display control means for rearranging and displaying the designated supply points in the supply order.

The second object is to provide the first means,
Further, it is achieved by the second means including the quality information input means for inputting the quality information of the recording medium and the display means for displaying the quality information input by the quality information input means.

[0009]

In the first means, the interleaf sheet supply location is designated by the supply location designation input means, the designated position is displayed on the supply location display means, and the interleaf sheet is supplied to the location.
Further, when a plurality of interleaf paper supply points are designated, the display positions are rearranged in order by the display means and then displayed in the rearranged order. Thereby, the operator can easily confirm the rearrangement position.

In the second means, if the quality information of the recording medium is input in advance, the quality information can be confirmed when an image is formed on the recording medium. The operator can easily and efficiently obtain an image of a desired quality on the recording medium by automatically or manually setting the image forming condition according to the quality information.

And the registration roller 35 is driven at the timing when the tip of the toner image on the photosensitive drum 7 is aligned.

The toner image on the photosensitive drum 7 is transferred to a transfer paper by the transfer charger 28. At this time, the surface of the photoconductor 7 is very smooth, and the adhesion between the photoconductor drum 7 and the transfer paper is large. Therefore, by lowering the potential of the transfer paper by the separation charger 27, the photoconductor drum 7 and the transfer paper are separated from each other. Release the adhesion of. Next, the transfer paper is separated from the photoconductor drum 7 by the separation claw 26, and the transfer paper thus separated is sent to the fixing unit 18 by the conveyor belt 21. The transfer paper sent to the fixing unit 18 is subjected to heat and pressure on the toner, and the toner image on the transfer paper is fixed on the transfer paper, and then the transfer paper is transferred to the reversing unit 19.
It is discharged to the sorter 20 via. When performing double-sided copying or the like, the sheets are discharged to the double-sided tray 22 via the reversing unit 19.

Since a small amount of toner image remains on the surface of the photosensitive drum 7 after the transfer, the PCC 25 is operated, the surface is cleaned by the cleaning brush and the cleaning blade in the cleaning unit 12, and the next quenching charger is used. The surface potential is made constant by 11 and the discharge lamp 9. These control timings are obtained mainly by a pulse generated in synchronization with the rotation of the photosensitive drum 7 or a reference pulse for driving the photosensitive drum 7.

Next, the configuration of the sorter 20 of this embodiment is shown in FIG.

When the motor 107 rotates in the H direction, the copy bundle is brought in the B direction. Push plate 112
Is returned in the B direction, the end holding plate 97 tries to return to the original state by the spring 111, but since the copy bundle is already on top, it is stopped under the copy bundle. When the moving plate comes to the home position, the motor 107 is stopped, and then the post-processing unit 6
1 is operated, and after the post-processing is completed, the motor is rotated again in the G direction to return the copy bundle in the A direction. When the position detection piece 103 turns on the tip position detection sensor again, the motor 10
7 stops, and the solenoid 114 turns off,
The coil spring 115 moves the upper chuck 109 upward, the copy bundle returns to its original position, and the end face pressing plate 97 also returns to its original position. Then, the motor 107 rotates in the H direction, pushes the moving plate 113 to the home position, and stops. In this way, the chuck unit 60 carries the copy bundle discharged onto the bin to the post-processing device and performs the operation of returning the copy bundle to the original position again.

FIG. 7 is a schematic diagram of the post-processing unit 61. A stapler will be illustrated and described as an example. This stapler pushes and bends the staple 119 in the cartridge 117 when the motor 116 is turned on by an electric signal. The staples 119 are connected in a strip shape by a thin tape and are rolled into the cartridge 117. The end of the staple 119 is a near-end sensor (optically reading reflective sensor) 118.
A near end signal is output when passing through.

FIG. 8 is a detailed view of the alignment shaft drive unit 95 shown in FIGS. 3 and 4. When the motor 120 makes one rotation, the aligning plate 70 rotates in a fan shape in the arrow AB direction via the cam 121, the lever 122, and the aligning shaft 71.

FIG. 12 is a diagram showing a concrete configuration example of the periphery of the paper feed cassette 40-1 of FIG. 1 as an example. The paper feed cassette 40-1 is provided with a bottom plate 411 on which a plurality of sheets of paper are placed so as to be able to move up and down. A size-preventing light-shielding plate (not shown) is fixed to the front end of the case 412 of the paper feed cassette 40-1, and the paper-shielding portion of the light-shielding plate is sandwiched between the cassette and the paper size to be stored in the cassette is detected. For example, the paper size detection 413 using five photo interrupters is arranged, and the case 4
A bottom plate raising arm 415 pivotally attached in a vertical direction by a rotating shaft 414 and provided with a right turning property by a spring (not shown) is provided on the back surface side of the unit 12.

Further, on the upper part of the paper feed cassette 40-1,
A paper (a photo interrupter) using a photointerrupter rotatably pivotably attached to a filler (an arc cheater) 417 integrally formed with a light shielding plate 416 at the rear portion by a rotating shaft 419 so that the light path is blocked by the rise of the light shielding plate 416. An end detection sensor 418 is arranged. The calling roller 29 receives the driving force from the main motor to turn on the paper feed clutch.
It is designed to rotate in the direction of the arrow.

Here, when the paper feed cassette 40-1 is mounted as shown in FIG. 12, the bottom plate raising arm 415 rotates upward from the rear surface side of the case 412, and the tip end thereof is cut out of the case 412. The bottom plate 411 is lifted upward while being abutted against the back surface of the bottom plate 411 through 412a, whereby the uppermost paper placed on the bottom plate 411 hits the calling roller 29 and is set at a position where it can be fed.

Further, by mounting the paper feed cassette 40-1, the paper size detection sensor 413 blocks the optical path of only the photo interrupter sandwiching the light shielding part of the size identifying light shielding plate, so that the corresponding signal, namely, A code indicating the paper size can be output to the control unit.

Further, the filler 417 is a paper feed cassette 40.
When -1 is not attached, as shown by the chain double-dashed line, it is in a position where it enters the paper end detection sensor 418 and blocks its optical path, and the bottom plate 411 is pushed up, and the tip end is pushed up by the topmost paper. When it is rotated, it rotates in the right-handed direction, whereby the light blocking plate 416 goes out of the inside of the paper end detection sensor 418 to release the blocking of the optical path.

As a result, the output signal of the paper end detection sensor 418 changes, and the presence or absence of paper in the paper feed cassette 40-1 can be determined by detecting it by the control unit.

A cutout (not shown) is formed in the portion of the bottom plate 411 facing the filler 417, and when the bottom plate 411 rises in a state where no paper is placed, the filler 417 is moved upward by the cutout. Since it is not rotated to, the control unit detects the absence of paper.

The operation and control of the copying machine according to the embodiment constructed as described above will be described.

First, FIG. 13 shows the overall processing procedure in the slip sheet mode of the copying machine in this embodiment. In the slip sheet mode, in this copying machine, the set sheet number input routine is first used to input the set sheet number from the ten keys 202 (step S1), and the slip sheet (chapter break) mode is selected (step S2). Then, the document is set on the ADF (step S3) and the wait state is maintained until the start key 20 is pressed (step S4). Then, the start key is turned on to perform initialization (step S5).

When the initial setting is completed, a document feed signal is transmitted to the ADF, the document is set at a copyable position on the contact glass (step S6), and the copy number counter and the discharged sheet number counter are cleared (step S7). ).
When the counter is cleared, a copying operation is performed to make a copy according to the set number of sheets (steps S8 and 9), and the discharge of the copy made according to the selected interleaving paper mode is controlled (step S10). .. Then, the copy operation and the subsequent steps are repeated until the number of copies reaches the set number (step S11).

When the copying operation is completed, a document feed signal is transmitted to the ADF and the document is ejected from the contact glass (step S12). If there is still an original, the next original is fed and the above-mentioned copying operation is repeated (step S1).

15). Then, perform post-processing such as stapling,
It ends (step S16).

The subroutine for inputting the number of sets in step S1 is executed in the procedure as shown in the flowchart of FIG. In this processing procedure, it is first checked whether or not the ten key 202 is pressed (step S21). Next, the pressed numeric keypad data is stored in the RAM 302 (step S22), the set number indicator 204 is turned on according to the set RAM data (step S23), and the process returns.

The interleaving mode setting subroutine of step S2 is performed in the procedure shown in FIG. In this process, it is checked whether or not the slip sheet key 225 is pressed (step S31), and if it is not pressed, the process returns, and if it is pressed, the slip sheet mode flag is set (step S32), and then the slip sheet is inserted. The supply position input process is executed (step S33) and the process returns.

The initialization sub-retaining in step S5 is executed in the procedure shown in the flowchart of FIG. In this procedure, first, the document number counter is cleared (step S41), and the conveyance drive motor is turned on (step S42). Next, it is checked whether or not the mode is the sort mode (step S43). If the mode is not the sort mode, the switching claw 46 is lowered so that the sheet is discharged to the paper discharge tray side (step S44). 46 is raised so that the copy is conveyed to the bin side (step S45) and the process returns. A in step S6
The DF document feeding subroutine is executed in the procedure as shown in the flowchart of FIG. In this procedure, ADF
A document feed signal is output to feed the document (step S51), and the document number counter is incremented by 1 (step S52), and the process returns.

The paper feed control subroutine of step S8 is executed in the procedure as shown in the flowchart of FIG. In this process, first, the input slip sheet data is checked to determine whether it is the slip sheet timing (step S
61). If it is the interleaf sheet timing, the interleaf sheet is fed (step S62), and if it is not the interleaf sheet timing, the plain sheet is fed (step S63) and the process returns.

The paper discharge control subroutine of step S10 is executed in the procedure as shown in the flowchart of FIG. In this process, first, it is checked whether or not the mode is the sort mode (step S71). If the mode is not the sort mode, the discharge sensor of the discharge tray is checked (step S77), and when the discharge sensor is turned on, the discharge counter is displayed. Add one (step S78) and return.

If it is the sort mode, the ejection sensor of the bin is checked (step S72), and the ejection sensor is turned on.
Then, the paper discharge counter is incremented by 1 (step S73).
Next, for the next stack operation, the current bin deflecting claw is turned off and the current bin deflecting claw one bin below is turned on (step S74). After this processing is completed, it is checked whether the set number of sheets and the number of ejected sheets are equal (check whether all the copies of one original are ejected) (step S75), and if they are ejected, the next operation is performed. Therefore, the deflecting claw of the current bin is turned off, and the deflecting claw of the leading bin of the block is turned on (step S76), and the process returns.

The post-processing subroutine of step S16 is executed in the procedure shown in the flowchart of FIG. In this process, it is checked whether the staple mode is set (step S81). If the staple mode is set, the staple process is executed for each bin (step S8).
2) Return. If the staple mode is not set, the staple process is not executed and the process returns.

FIG. 21 is a flow chart showing the processing procedure of the slip sheet input processing. In this process, first, step S
The input of the numeric keypad 202 is judged at 91, and if there is an input,
In other words, if pressed, the data is stored in the memory of the chapter currently being input (step S92) and displayed at the display positions 503 to 512 (FIGS. 23 to 25) of the chapter being input (step S93), Execute the numeric keypad input process.

When it is determined in step S91 that the numeric keypad is not input, the #key 502 (FIGS. 23 to 25) is input (step S94). If it is pressed, the chapter being input is the tenth chapter, that is, It is judged whether or not it is the final location of paper designation (step S95), and if it is not the tenth chapter, input of the next chapter is started (step S96). On the other hand, step S9
If the chapter currently being input in 5 is the final location of the interleaf sheet designation, the interleaf sheet position input is terminated, the interleaf sheet data rearrangement processing is executed (step S98), and the process returns.

If the # key 502 has not been pressed in step S94, it is determined whether the designated end key has been pressed (step S97). If not, the process returns to step S91 and the subsequent processing is executed. If it is pressed, the rearrangement process of step S98 is executed (step S98) and the process returns.

A display example at this time is shown in FIGS. 23 and 24. The subroutine for rearranging the interleaf data in step S98 is executed in the procedure as shown in the flowchart of FIG.

That is, in this process, the interleaf paper supply location data stored for each chapter is temporarily stored in another memory (step S101), the data is sequentially determined, and the data having the smallest value is determined as the first chapter. For the eyes, that is, as the first interleaf data to be supplied, it is stored in the first chapter memory, and the next smaller data is stored in the second chapter memory. In the memory (step S102). Then, when all the data are stored, the stored data is stored in each of the display positions 503-5.
It is redisplayed on 12 (step S103) and the process returns.
This display example is shown in FIG.

Next, the operation and control in the cover mode of this copying machine will be described. FIG. 26 is a flowchart showing the processing procedure in the cover mode. The cover mode is basically the same as the interleaf paper mode of FIG. 13 except for the subroutines of step S2 and step S8, and therefore only different processing parts will be mainly described.

In the cover mode, the subroutine of step S2 shown in the flowchart of FIG. 13 is the subroutine of setting the cover mode (step S2 '-FIG. 27) and the subroutine of the paper feed control of step S8, which is a subroutine unique to the cover mode (step S8'-FIG. 28), the front cover mode or the back cover mode is selected in step S2 ', and the copy discharge control made in accordance with the cover mode selected in step S8' is controlled. ing.

Specifically, the cover mode setting subroutine is as shown in the flowchart of FIG. In this process, it is checked whether the cover key 228 has been pressed, and if not pressed, the process returns (step S111). If it is pressed, the upper and lower bin sensors are checked, and if there is paper on at least one side, the front cover mode, the front and back cover mode, the sort mode and the staple mode are reset and the process returns (steps S112, 117, 122, 123, 124). , 12
5). If there is no paper, it is checked whether it is already in the front cover mode (step S112). If it is already the front cover mode, the front cover mode is reset (step S113), and the front and back cover modes, the sort mode and the staple mode are set. Reset (step S
114, 115, 116) Return.

If it is not the front cover mode, it is checked whether the front cover mode is already set (step S11).
