Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a finisher for a copying machine which binds a copied copying material from a copying machine body with a stapler and discharges it.

[0002]

2. Description of the Related Art FIG. 1 shows a finisher of a conventional copying machine.
The description will be as follows with reference to FIGS.

As shown in FIGS. 11 and 12, the finisher of the copying machine conveys the copied copying paper 38 sent from the copying machine main body (not shown) to the conveying roller 32.
To the paper feed path 33, a staple tray 37 on which the copy paper 38 dropped and discharged via the carry roller 32 is stacked, and whether the copy paper 38 from the carry roller 32 has dropped onto the staple tray 37. A sensor (not shown) that detects the copy paper 3 on the staple tray 37.
The reference guide 40 that holds the rear end of the booklet 8 and that serves as a guide in the extrusion direction during the extrusion of the bookbinding product, and the reference after the sensor detects that the copy paper 38 has dropped onto the staple tray 37. The jogger 31 that moves the front end of the copy paper 38 held by the guide 40 toward the reference guide 40 (in the direction of the arrow shown in FIG. 12).
The stapler 34 is used to bind the width of the copy paper 38 to the staple tray 37, and the pusher 39 pushes the bound product to the offset tray 36.

According to the above construction, the copy paper 38 drops onto the staple tray 37 via the conveying roller 32,
After the discharge is detected by the sensor, the jogger 31 is moved to the widthwise direction. Eventually, the jogger 31 reaches the front end of the copy paper 38, and the width-shifting operation is continued. Note that this width-shifting operation is performed on the copy paper 38.
The process is continuously performed until the trailing end reaches the reference guide 40.

When the width adjustment operation by the jogger 31 is completed as described above, the stapler 34 drives the staples into a predetermined position on the copy paper 38 for bookbinding. The bookbinding product is pushed out in a predetermined direction (direction perpendicular to the arrow shown in FIG. 12) by the pusher 39, and is discharged to the offset tray 36.

As described above, it is well known that the copied copy paper 38 is width-shifted by the jogger 31 and then bound by the stapler 34 and discharged.

[0007]

However, in the above-mentioned conventional technique, the jogger 31 performs the width-shifting operation of the copy paper 38 until it is detected that the copy paper 38 is dropped on the staple tray 37. Absent. That is, the time required for the jogger 31 to start the width adjusting operation and to complete the width adjusting operation becomes long. Therefore, in particular, when the number of copy papers 38 to be bound is large, the accumulated time loss becomes very large, and there is a problem that it cannot be applied to a copying apparatus that requires high-speed processing.

[0008]

In order to solve the above-mentioned problems, the finisher of the copying apparatus of the present invention discharges the copied copying material from the copying apparatus main body to the staple tray via the conveying means and discharges it. It is characterized in that the following means are taken in a finisher of a copying machine for binding a predetermined number of the copied materials to be bound by a stapler and discharging the book.

That is, the finisher of the copying apparatus outputs a copy material aligning means for aligning the copy material discharged to the staple tray and a timing start signal when the copied copy material reaches a predetermined position in the conveying means. The position detecting means for changing the time counting time, the time counting means for starting the time counting operation when the time counting start signal is input, and outputting the width adjusting start signal after the time measuring time has elapsed; Is input, the width of the copying material discharged to the staple tray is adjusted to a predetermined position with respect to the stapler.

[0010]

According to the above construction, the copied copying material from the copying apparatus main body is sent to the conveying means, and the copying material discharged by the conveying means falls on the staple tray. At this time, while the copying material is falling on the staple tray,
When the position detection means detects that the predetermined position has been reached, the position detection means sends a time measurement start signal to the time measurement means.

When the time counting start signal is input, the time counting means starts the time counting operation. Then, when the preset time counting time has elapsed, the width-shift start signal is output from the time counting means to the width-shifting means. Even during the time counting operation, the discharging operation of the copying material is continuously performed toward the staple tray by the conveying means. Also, the setting of the clock time is
This is performed according to the speed at which the conveying means conveys the copied copying material.

Then, when the width-shifting means receives the width-shifting start signal, the width-shifting means starts the width-shifting operation even though the aligned copy material is not placed on the staple tray. After that, the copying material discharged by the conveying means and dropped on the staple tray is aligned on the staple tray by the aligning means, so that it does not become unstable. Eventually, the crossing means will reach the already aligned copy material. Then, the copy material is width-shifted in a predetermined direction by the width-shifting means and placed at a predetermined position with respect to the stapler.

That is, since the width-shifting operation by the width-shifting means is started by the time the copying material is completely dropped on the staple tray, the width-shifting operation can be performed in parallel with the discharging operation of the copying material to the staple tray. Therefore, the time required to complete the width-shifting operation is shortened.

After performing the above operation on a predetermined number of copy materials to be bound, binding is performed by the stapler, and the bound product is ejected.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.
The explanation is based on the following.

As shown in FIG. 2, the finisher 28 of the copying apparatus according to this embodiment has, for example, a document stopper 27.
A document set in a document feeding device 26 including a sheet is fed through a paper feeding device 25 to a copy sheet, which is a copying material supplied to the copying apparatus main body, for double-sided copying or single-sided copying, and is conveyed in the copying apparatus main body. This is a device for aligning a predetermined number of copied copy papers sent via rollers and the like for bookbinding and discharging the booklet to an offset tray.

As shown in FIG. 3, the finisher 28 feeds the copied copy paper (hereinafter simply referred to as copy paper) sent from the copying apparatus main body (not shown) to the transfer roller group 22. A path group 21 (conveying means) and a position sensor group 2 which outputs a timing start signal when it is detected that the copy paper has passed a predetermined position of the paper conveying path group 21.
3 (position detecting means), a timer 18 (clocking means) that starts a clocking operation when a clocking start signal is input and outputs a width-shifting start signal after the clocking operation is finished, and drops via the transport roller group 22. A reference tray (not shown) that holds the staple tray 10 on which the discharged copy paper is loaded and the front end of the copy paper on the staple tray 10 and plays a role of a guide in the extrusion direction when the bookbinding product is extruded. And a paddler 7 for aligning the copy paper dropped on the staple tray 10 by a rotation operation, and a predetermined direction with respect to the copy paper when a width-shift start signal is input (a direction perpendicular to the side surface of the reference guide). The jogger 9 (width-shifting means) that starts the width-shifting operation, the stapler 11 that binds the width-shifted copy paper on the staple tray 10, and the stapler 11. Pusher 1 to push staple paper (hereinafter referred to as bookbinding product) to the offset tray 15
2 and mainly.

As shown in FIG. 1, the paper transport path group 21 is the entrance of the finisher 28, and is the transport path entrance 1 through which the copy paper is fed from the copying apparatus main body, the first transport path 3, and the first transport path 3. It consists of two transport paths 4. The transport roller group 22 is composed of the first transport roller 5 and the second transport roller 6. The copy paper that has passed through the first transport path 3 or the second transport path 4 is discharged via the first transport roller 5 or the second transport roller 6 and drops onto the staple tray 10.

The transport path switching device 2 determines whether the copy paper sent from the copying apparatus main body passes through the first transport path 3 or the second transport path 4. That is, as shown in FIG. 1 or 5, the transport path switching device 2 is made of, for example, a wing-shaped member, is provided in the vicinity of a branch point of the first transport path 3 and the second transport path 4, and has a clutch (illustration). By turning around the fulcrum 2a when “ON” is turned on, it is arranged at either one of the first position and the second position (described later). The switching operation of the transport path switching device 2 is not performed when the clutch is OFF.

For example, when the transport path switching device 2 is switched to the position (first position) shown by the solid line in FIG. 5, the second transport path 4 is closed. As a result, the copy paper from the copying apparatus main body is ejected via the conveyance path inlet 1, the first conveyance path 3, and the first conveyance roller 5, and drops onto the staple tray 10. On the other hand, when the transport path switching device 2 is switched and placed at the position (second position) shown by the dotted line in FIG. 5, the first transport path 3 is closed, so the copy paper from the copying apparatus main body is The sheet is discharged via the transport path inlet 1, the second transport path 4, and the second transport roller 6, and falls onto the staple tray 10.

The operation of the transport path switching device 2 and the like when a plurality of copies of the same item are continuously bound (in the multi mode) will be described below.

That is, after the bookbinding process of the first part is completed,
The transport path switching device 2 is arranged at the position shown by the dotted line in FIG. Then, when the first sheet of the second portion reaches the first transport roller 5 via the transport path inlet 1 and the first transport path 3, the rotation operation of the first transport roller 5 is stopped, and the first sheet of the first sheet is stopped. The copy paper is not ejected and is held in the first transport path 3. It should be noted that the first copy sheet is the first transport roller 5
It can be detected by a position sensor (not shown) such as a photo interrupter, for example.

The transport path switching device 2 is arranged from the position shown by the solid line in FIG. 5 to the position shown by the dotted line. Subsequently, when the second sheet of the second section passes a predetermined position (installation position of the switch SW4 described later) in the second transport path 4, the rotation operation of the first transport roller 5 is restarted and the first transport roller 5 is restarted. And the second
The transport rollers 6 are both rotated, and the above-mentioned first and second copy sheets are ejected at approximately the same time and fall onto the staple tray 10. The timing of the rotation operation of the above-mentioned transport rollers and the timing of the switching operation of the transport path switching device 2 are
For example, it is controlled by the main body of the copying apparatus.

The transport path switching device 2 in the single mode is, as shown in FIG. 4, held in the first position from beginning to end.

As shown in FIG. 5, a switch SW1 is provided at a predetermined position of the first transport path 3 so that copy paper passing through the first transport path 3 is passing through the predetermined position.
The switch SW1 is turned on. This ON signal is used as a timing start signal. Similarly, the second transport path 4
A switch SW4 is provided at a predetermined position of
When the copy sheet passing through the transport path 4 passes through the predetermined position, the switch SW4 is turned on.
The switches SW1 and SW4 are not limited to specific switches, and may be composed of, for example, a photo interrupter which is an optical sensor or a mechanical switch.

When the paddler 7 rotates counterclockwise and the third conveyor roller 14 rotates clockwise, the paddle 7 drops onto the staple tray 10 via the first conveyor roller 5 or the second conveyor roller 6. The trailing edge of the copy paper is moved to the stopper 8 and the alignment operation is performed. This prevents the copy paper discharged onto the staple tray 10 from becoming unstable. In addition, the third
The transport roller 14 is provided with a switch SW3, and while the ejected copy paper is passing through the roller 14, the switch SW3
Turns on.

The jogger 9 starts the width-shifting operation after receiving the width-shifting start signal output from the timer 18 after the predetermined time has elapsed. The time measured by the timer 18 is set such that the width-shift start signal is output while the copy paper discharged from the first transport roller 5 is falling toward the staple tray 10. That is, the jogger 9 does not reach the front end of the copy sheet until a predetermined time has elapsed from the start of the width-shifting operation. After that, the jogger 9 reaches the front end of the copy paper and pushes the front end in a direction perpendicular to the alignment direction until it comes in contact with the reference guide, thereby performing the width-shifting operation. Here, the aligning direction means the moving direction of the copy paper when the aligning operation is performed.

As a result of the width-shifting operation, the copy paper is placed at a predetermined position with respect to the stapler 11. Then, based on a command from the main body of the copying apparatus, staples are driven into a predetermined number of copy sheets to be bound.

The bookbinding product by the stapler 11 is pushed out to the offset tray 15 by the pusher 12. At this time, the third transport roller 14 rotates counterclockwise to assist the pushing operation of the bookbinding product.

The offset tray 15 has a vertical movement mechanism (elevator) 17. A moving device (shift unit) 16 is provided in the up-and-down moving mechanism 17, and when a plurality of copies of the same item are continuously bound, the moving device 16 always causes the first bound product to be the third transport roller. 1
The vertical movement control is performed so as to maintain a predetermined distance from No. 4. Thus, in the multi mode in which a plurality of copies of the same book are continuously bound, the first bookbinding product does not hinder the ejection of the later bookbinding product.

The operation of the finisher 28 of the copying machine having the above structure will be described below with reference to FIGS. 6 to 10. The finisher 28 is roughly divided into
It has two operation modes, an offset printing mode and a staple mode. In this staple mode, further, when only one copy is bound (single mode) and when the same one is bound in multiple copies (multi-binding). Mode) and subdivision.

First, the operation of the finisher 28 in the offset printing mode will be described with reference to FIG. That is, it is determined whether or not the finisher 28 has received a command regarding the offset print number from the copying apparatus main body (S1). Until the offset printing number is received, the process does not proceed to the next step. When the offset print number is received in S1, this offset print number is set as the target processed number (S2).

Next, it is determined whether or not a start command has been received from the copying apparatus body (S3). Do not move to the next step until the start command is received. When the start command is received, the start process is executed (S
4). In this start process, the following processes (1) to (3) are performed. (1) The first and third transport rollers 5 and 14 are rotated counterclockwise. (2) The clutch is turned on to perform the switching operation, and the transport path switching device 2 is arranged at the first position. (3) The paper ejection guide (member indicated by reference numeral 13 in FIG. 1) is arranged at the lower position.

Then, the number of offset printing sheets is set (cleared) to 0 (S5). Then, it is determined whether the switch SW1 of the first transport path 3 is turned on (S6). As a result, it can be detected whether or not the copy paper from the copying apparatus main body has passed through the predetermined position of the first transport path 3. The process does not proceed to the next step until the switch SW1 is turned on.

When it is confirmed in S6 that the switch SW1 is turned on, the process proceeds to S7, in which the switch SW3 is
Is turned on. As a result, it is determined whether or not the copy paper discharged via the first transport path 3 and the first transport roller 5 has reached the third transport roller 14.
The process does not proceed to the next step until the switch SW3 is turned on.

When it is determined in S7 that the switch SW3 is turned on, the process proceeds to S8, in which the switch SW3 is turned on.
It is determined whether or not FF has been performed. As a result, it is determined whether or not the trailing edge of the copy sheet is discharged via the third transport roller 14 and dropped onto the offset tray 10. The process does not proceed to the next step until the switch SW3 is turned off.

When it is determined in S8 that the switch SW3 is turned off, the number of sheets actually subjected to the offset printing is counted up (S9). Then, the process shifts to S10, and it is determined whether the actually processed offset number of sheets has reached the target number of processed sheets set in S2. S
In 10, if the actual number of processed sheets has not reached the target number of processed sheets yet, the process returns to S6 and the above-described processing is repeated. On the other hand, if the actual number of processed sheets reaches the target number of processed sheets in S10, the number of processed sheets of offset printing is set (cleared) to 0 (S11), as in S5.

After that, the offset tray 15 which is the paper discharge tray is lowered (S12), and the offset (shift) operation of the offset tray 15 is performed (S13). Then, the offset tray 15 is raised (S14).
After that, the process shifts to S15, where it is determined whether or not an offset printing mode end command is received from the copying apparatus main body. If the end command is not received in S15, S6
Returning to, while the above-described processing is performed, when the termination command is received, a predetermined termination processing is performed in S16. In addition,
In the ending process, the clutch in the ON state is turned off, and the rotation of the transport rollers 5 and 14 in the rotating state is stopped.

The operation of the finisher 28 in the staple mode in the single mode will now be described with reference to FIG.
The description will be made with reference to.

That is, in the single mode,
First, it is determined whether the finisher 28 receives from the copying apparatus main body a command relating to the number of staples, which indicates how many copy sheets are stapled and bound (S21). Until the above number of staples is received,
Do not move to the next step. When the number of staples is received in S21, this number of staples is set as the target processed number (S22).

Next, it is confirmed whether or not a start command is received from the copying machine body (S23). Do not move to the next step until the start command is received. When the start command is received, the start process (see the processes (1) to (3) described above) is executed (S24).

Then, the actual number of processed sheets is set (cleared) to 0 (S25). Then, it is determined whether or not the switch SW1 of the first transport path 3 is turned on (S2
6). As a result, it is determined whether or not the copy sheet from the copying apparatus main body has reached the predetermined position on the first transport path 3. The process does not proceed to the next step until the switch SW1 is turned on.

When it is confirmed in S26 that the switch SW1 is turned on, the process proceeds to S27 and the switch SW1 is turned off.
It is determined whether or not FF has been performed. As a result, it is determined whether or not the copy paper has passed through the first transport path 3. The process does not proceed to the next step until the switch SW1 is turned off.

When it is determined in S27 that the switch SW1 is turned off, the timer 18 is reset (cleared), and the timekeeping operation for a preset predetermined time (timekeeping time) is started (S28). Then, the actual number of processed sheets is counted up (S29), and the process proceeds to S30. S30
Then, it is determined whether or not the predetermined time has elapsed, and the process does not proceed to the next step until the predetermined time elapses.
During this time, the trailing edge of the copy paper, which is discharged through the first transport roller 5 and drops onto the staple tray 10 by the clockwise rotation of the third transport roller 14 and the counterclockwise rotation of the paddler 7, is Move to stopper 8. This ensures that the dropped copy sheets are aligned without becoming unstable.

When a predetermined time has passed in S30 (the copy paper is falling), a width-shift start signal is sent to the jogger 9 to start the width-shift operation by the jogger 9, and eventually the jogger 9 is moved.
Comes into contact with the copy paper discharged via the first transport roller 5, moves the copy paper to a predetermined position in the paper width direction, and performs a width-shifting operation (S31), and proceeds to S32.

In S32, the total number of copy papers that have been width-aligned is
It is determined whether or not the target number of processed sheets set in S22 matches. Then, when it is determined that the number of processed sheets does not match the target number of processed sheets, the process returns to S26, and when it is determined that the number of processed target images does not match, the process proceeds to S33. In S33,
The number of processed sheets counted up in S29 is set (cleared) to 0.

Then, the stapled sheets are stapled into the copy-processed sheets corresponding to the target number of sheets to be width-shifted, and the booklet is bound (S34). This bound product (staple paper) is pushed out by the pusher 12 to the offset tray 15 which is a paper discharge tray. At this time, the third transport roller 14 rotates counterclockwise to assist the pushing operation of the bookbinding product.

When the discharge of the bookbinding product is completed in S35, the process proceeds to S36, in which the vertical movement mechanism 15 causes the offset tray 15 to move the copy paper located at the top of the bookbinding product to the third transport roller 14. On the other hand, after the vertical movement is adjusted so as to maintain the predetermined distance (S36), the process proceeds to S37. In S37, it is determined whether or not the finisher 28 has received a single mode end command from the copying apparatus main body. And when the above end command is received,
The process proceeds to S38, and the above-described termination process is performed to complete all the single mode processes. Note that the process does not proceed to S38 until the end command is received in S37.

The operation of the finisher 28 in the multi-mode for binding a plurality of copies of the same item continuously will be described below with reference to FIGS. 8 to 10.

That is, in the multi-mode, as shown in FIG. 8, first, the finisher 28 receives from the copying apparatus main body a command relating to the number of staples indicating the number of sheets of copy paper to be stapled for bookbinding. It is determined whether or not (S41). The process does not proceed to the next step until the number of staples is received. S41
When the number of staples is received, this number of staples is set as the target number of sheets to be processed (S42).

Next, it is determined whether a start command has been received from the copying apparatus body (S43). Do not move to the next step until the start command is received. When the start command is received, the start process (see the processes (1) to (3) described above) is executed (S44).

Then, the actual number of processed sheets is set (cleared) to 0 (S45). Then, it is determined whether or not the switch SW1 of the first transport path 3 is turned on (S4
6). As a result, it is determined whether or not the copy sheet from the copying apparatus main body has reached the above-mentioned predetermined position of the first transport path 3.
When the switch SW1 is turned on in S46, the process proceeds to S47, and it is determined whether or not the switch SW1 is turned off. As a result, it is determined whether or not the copy paper has passed through the first transport path 3. The process does not proceed to the next step until the switch SW1 is turned off.

On the other hand, if it is determined in S46 that the switch SW1 is not turned on, then the flow shifts to S71 in FIG.
In S71, it is determined whether or not the bookbinding product (staple paper) has been discharged onto the offset tray 15. When the bookbinding product has been discharged, the process proceeds to S73, where it is determined whether the vertical movement adjustment of the offset tray 15, which is the paper discharge tray, has already been performed. By the way, when it is determined in S71 that the bookbinding product is not yet discharged, the process proceeds to S72, in which the bookbinding product is discharged, and then S in FIG.
Return to 46. On the other hand, when the vertical movement adjustment of the offset tray 15 is completed in S73, it is determined whether or not an end command is received from the copying apparatus main body (S7).
5).

When it is confirmed in S75 that the end command is received, it is confirmed whether the finisher 28 has received the multi-mode end command from the copying apparatus main body. When the end command is received, S76
Then, the above-mentioned termination processing is performed and all the multi-mode processing is completed. On the other hand, if the end command is not received in S75, the process returns to S46 and the above-mentioned process is executed.

At S47, the switch SW1 is turned off.
When it is determined that the timer 18 is reset, the timer 18 is reset (cleared) and the timekeeping operation for a preset predetermined time is started (S48). Then, the actual number of processed sheets is counted up (S49), and the process proceeds to S50.

In S50, the staple tray 10 is actually
It is determined whether or not the number of copy sheets discharged to the upper side is one. As a result, when the number of processed sheets is not one, S in FIG.
The process proceeds to 66, in which it is determined whether the predetermined time set in the timer 18 has elapsed, and the process does not proceed to the next step until the predetermined time elapses. During this time,
Due to the clockwise rotation of the third transport roller 14 and the counterclockwise rotation of the paddler 7, the trailing edge of the copy sheet discharged through the first transport roller 5 and dropped on the staple tray 10 reaches the stopper 8. Be moved. As a result, the ejected copy sheets are aligned without becoming unstable.

When a predetermined time has passed in S66, the timer 1
A width-shift start signal is sent to the jogger 9 from 8 and the width-shift operation by the jogger 9 is started. Eventually, the jogger 9 is discharged through the first transport roller 5 and abuts on the copy paper that has fallen, and the copy paper Is moved to a predetermined position in the paper width direction to perform the width-shifting operation (S67), and the process proceeds to S68.

In S68, the total number of copy papers that have been width-aligned is
It is determined whether or not it matches the target number of processed sheets set in S42. Then, when the target processed number does not match, the process returns to S46, while when the target processed number matches, the process returns to S6.
Move to 9. In S69, the number of processed sheets counted up in S49 is set (cleared) to 0.

Then, the stapler 11 is stapled and bound to the target number of copy sheets that have been width-shifted, and after binding (S70), the process returns to S46 and the same processing as described above is performed.

By the way, in S50, the number of processed sheets is 1
In the case of S, the process proceeds to S51, and it is determined whether or not the staple tray 10 is in the ejectable state. Then, when the copy paper can be discharged onto the staple tray 10, the process proceeds to S66 (see FIG. 10) and the above-described processing is performed. On the other hand, if the copy paper cannot be discharged, the process proceeds to S52, and the first copy paper of the second part of bookbinding passes through the first transport path 3 and reaches the first transport roller 5, but at this time, the first transport is performed. Since the rotation operation of the roller 5 is stopped (while the second carrying roller 6 is in a rotating state), the copy paper is held in the first carrying path 3. Then, in S53, the transport path switching device 2 is switched and placed at the second position shown by the dotted line in FIG. That is, the second sheet of the second bookbinding portion passes through the second transport path 4.

Then, the switch SW in the second transport path 4
It is determined whether or not 4 is in the ON state (S54). When it is detected that the switch SW4 is in the ON state, S
Then, the flow shifts to 55, where it is determined whether the switch SW4 is turned off. When it is detected that the switch SW4 is turned off, the process proceeds to S56. Note that in S55, the process does not proceed to the next step until it is detected that the switch SW4 is turned off.

In S56, the transport path switching device 2 is switched and placed at the first position shown by the solid line in FIG. Copy paper from the copying apparatus main body thereafter passes through the first transport path 3. After that, the process proceeds to S57, and the transport operation is restarted for the first copy sheet that has been held in the first transport path 3. Eventually, the second copy sheet in the second transport path 4 is discharged onto the staple tray 10 via the second transport roller 6. That is, the first copy sheet and the second copy sheet are ejected at substantially the same time and fall onto the staple tray 10.

By the way, in S54, the switch SW
If No. 4 is not in the ON state, the process proceeds to S62 (see FIG. 9), where it is determined whether the first copy has been bound and then discharged onto the offset tray 10. If it has been discharged, the process proceeds to S64, and it is determined whether the offset tray 15 has been adjusted for vertical movement. If the vertical movement adjustment has been completed, the process returns to S54 and continues. If the vertical movement adjustment of the offset tray 15 has not been performed yet, the process proceeds to S65, and after the vertical movement adjustment of the offset tray 15 is performed, the process returns to S54 and continues.

If it is determined in S62 that the first part of the bookbinding product is not ejected to the offset tray 15, the bookbinding product is ejected to the offset tray 15 (S6).
3) After that, it returns to S54 and processing is executed.

As described above, according to the above configuration, the second
While the first and second copy sheets of the set are placed on the staple tray 10 at substantially the same time, the binding of the first set is performed by the stapler 11 as described above, and the bound product is pushed. Is discharged to the offset tray 15.

Further, according to the configuration of the above embodiment, when the switch SW1 detects that the copy sheet from the copying apparatus main body has passed the predetermined position in the first transport path 3, the jogger 9 is moved to the widthwise direction. Is started, the time required to end the width-shifting operation is significantly shortened compared to the conventional case. Therefore, the present invention can be sufficiently applied to a copying machine that requires high-speed processing.

According to the finisher of the copying apparatus of the present invention,
As described above, the copy material aligning means for aligning the copy material discharged to the staple tray, the position detecting means for outputting the time counting start signal when the copied copy material reaches the predetermined position in the conveying means, and the time counting When the time can be changed and the time counting start signal is input, the time counting operation is started, and after the time counting time elapses, the time counting means that outputs the width adjustment start signal and the staple when the width adjustment start signal is input. The copy material discharged to the tray is provided with a width-approaching means for moving the copy material in a predetermined direction so that the copy material comes to a predetermined position with respect to the stapler.

Therefore, the width-shifting operation can be performed in parallel with the discharging operation of the copy material to the staple tray, and the time required until the completion of the width-shifting operation can be shortened. However, it can handle it sufficiently.

Further, if the width-adjusting operation is performed while the copy material is being discharged (dropped) onto the staple tray, the copy material may become unstable. However, the present invention has a copy material aligning means. Therefore, it is possible to reliably prevent the copying material from becoming unstable due to the matching operation.

Further, since the setting of the time measuring time of the time measuring means can be changed according to the speed at which the conveying means conveys the copied copying material, it can be applied to the models having different conveying speeds.
Therefore, the effect that the finisher of a copying machine having high versatility can be supplied is also obtained.
