2. Description of the Related Art In recent years, with respect to copiers, their functions have been diversified and upgraded, and operability has been improved. The “multi-job mode”, which is positioned as one of the modes, is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-140957, and is a process that enables continuous copy processing for a plurality of document bundles having different copy conditions. Mode, which is performed using the ADF. That is, when the copy process for the first document bundle is a first job and the copy process for the second document bundle is a second job, the first document bundle is first set on the document table of the ADF to copy the first job. A condition (copy mode) is input, and a second original bundle is set on the first original bundle in a state where the second original bundle is partitioned by the original partitioning means.
By inputting the copy mode of the job and starting the copy, the copy process is performed continuously in the order of the first job and the second job.

[0003] Further, there is a market in which a post-processing device having a sorting function and a stapling function in order to improve post-processing performance after copying is put on the market. Japanese Patent Application Laid-open No. Sho.
There are control methods disclosed in Japanese Patent Application Laid-Open No. 289865/1990 and Japanese Patent Application Laid-Open No. 2-233468.

However, if the first job and the second job are simply processed continuously in a mode setting involving post-processing with the transfer sheet discharge destination as a post-processing device,
Post-processing of the second job may not be performed normally.

For example, when performing staple processing in a post-processing apparatus, it is necessary to perform a jogger operation for aligning the transfer paper discharged on each bin. However, the transfer paper size used in the second job is larger. When the transfer paper size used in the first job is smaller than the transfer paper size used in the first job, the jogger operation cannot be performed on the transfer paper in the second job, so that there is an inconvenience that normal stapling cannot be performed.

A recording paper supply unit 13 including a belt, a conveying roller, a registration roller, and the like is provided. Further, at the transfer position, the photosensitive member 1 is moved under the action of the transfer / separation charger 7.
A fixing device 14 for performing a fixing process on the transfer paper 12 to which the above image has been transferred is provided, and a paper discharge roller 15 is provided on the paper discharge side. A three-roller pair 16 for switching the conveyance direction is provided at a position before the discharge roller 15, and the conveyance is switched to the discharge roller 15 as it is, and further, the conveyance is performed to the reversing path 17 according to the set mode and pulled back. , Or once discharged onto the double-sided tray 18 to be used for double-sided copying or the like.

Further, the ADF 3 is configured as shown in FIG. First, a document table (first placing means) 21 for placing and setting a group of documents as one document bundle is provided, and the sheets are separated and fed one by one from the lowest sheet side toward the contact glass 9 side. Crescent roller 22, separation roller 23, separation blade 24 pair, pull-out roller pair 25
Are provided in order. A conveyer belt 27 supported and rotated by a plurality of rollers 26 is provided on the contact glass 9 so as to be continuous therewith. A document conveying means 28 for automatically setting a position (exposure position) is provided. On the paper discharge side of the transport belt 27, a paper discharge transport path 29 for turning upside down is formed so that a document can be discharged onto a paper discharge tray (second mounting means) 30 located above the transport belt 27. Is configured. Note that, in the case of a double-sided document, the paper discharge conveyance path 29 also includes a conveyance path for double-sided processing in which the sheet is set back on the contact glass 9 again around the turn roller 31. In this way, the document placed on the document table 21 is unidirectionally conveyed to the discharge tray 30.
DF3 is configured.

Here, such an ADF 3 can place a plurality of document bundles on the document table 21. In order to cope with the multi-job mode by notifying the control system of the separation of the document bundles, one group is used. A partitioning unit (partitioning means) 32 for partitioning each document is provided on one side of the document table 21. The configuration and operation will be described with reference to FIGS. First, a partition plate 33 that enters between document bundles and performs actual partitioning is provided to be able to advance and retreat and swing on the document table 21 by a long hole 33a that is loosely fitted to a pin 34 fixed to the ADF main body. . A concave portion 21a is formed in a part of the original table 21 side, into which the leading end of the partition plate 33 enters in a horizontal state in a state where the original is gone. A stepping motor 35 is provided as a driving source for rotating and displacing the partitioning plate 33, and a connecting pin 38 provided on the other end of the driven gear 37 on the shaft 37a meshed with the driving gear 36 on the motor shaft is partitioned. It is connected to the middle part of the plate 33. A detection piece 37b is formed on a part of the shaft 37a of the driven gear 37 so as to protrude therefrom. A paper detection sensor 39 having a photo interrupter configuration for detecting the presence or absence of a document on the document table 21 using the detection piece 37b is provided. It is provided at a predetermined position. Further, the pin 34 side of the partition plate 33 is formed in a fan shape and protrudes downward, and a detection piece 33b is formed to project from a lower end thereof, and the state of the partition plate is determined by using the detection piece 33b. Is provided at a predetermined position.

In such a configuration of the partition unit 32, first, when the detection piece 37b is at the position of the document detection sensor 39, the reference position is used, and at this time, it is determined whether or not there is a document on the document table 21. When there is no original bundle P on the original table 21, the partition plate 33 is at a horizontal position as shown by a solid line in FIG. At this time, the detection piece 33 of the partition plate 33
Since b is detected by the partition plate detection sensor 40, it is determined that the leading end of the partition plate 33 has advanced onto the document table 21. On the other hand, when there is a document bundle P on the document table 21, the partition plate 33 is at a position as shown in FIG. 6B (a position as shown by a virtual line in FIG. 6A). The detection piece 33b is located at a position deviated from the partition plate detection sensor 40. In this state, the presence or absence of a document on the document table 21 can be identified by the paper detection sensor 39. The partition plate 33 is driven to rotate by a stepping motor 35 and descends sequentially.

Now, as shown in FIGS. 4 and 6 (b), the partition unit 32 and the like in the case of using the two original bundles of the first original bundle P1 and the second original bundle P2 in the multi-job mode. The operation will be described. First, when the operator gives a multi-job mode execution command prior to document setting, the ADF 3 leaves the normal mode and enters the multi-job mode. Then, the first document bundle P1 is set on the document table 21. After the setting, the partition plate 33 is driven to descend, and the leading end thereof is placed on the first document bundle P1 as shown in FIG. 6B. This is the state of detecting the set of the first document bundle P1. The driving of the partition plate 33 may be automatically performed after the document set is detected.
The process may be started by pressing a copy start button. After the first set of originals P1 and the partition plate 33 are set, the second set of originals P2 is set on the first set of originals P1 as shown in FIGS. 4 and 6B. And the first,
First and second jobs (two-sided / one-sided, original size, number of copies, presence / absence of post-processing, contents, etc.) are set for each of the two original bundles P1 and P2, and the copy start button is pressed. Then, first, a set first job is executed for each document of the first set of first documents P1, and a copy is obtained. When the processing of the first document bundle P1 is completed, the partition plate 33
Has been lowered to the position shown by the solid line in FIG. 6 (a), it is known that the first original bundle P1 has disappeared, and the first job is terminated. The second job will be executed.

The sorter unit 4 performs post-processing, such as sorting / stacking, and post-processing, such as staple binding and punching, on the copied transfer paper 12, the details of which are shown in FIG. This will be described with reference to FIG. First, as shown in FIG. 7, an entrance guide plate 41 is provided at a receiving port of the copied transfer paper 12 discharged from the paper discharge roller 15 of the copying machine main body 2, and subsequently, the transfer paper 12 is moved upward. Upper and lower conveyor belts 42, 4 for conveying
3, a switching claw 44 and switching guide plates 45 and 46 are provided. A transport roller pair 47 and a paper discharge tray 48 are provided in an upper path by the switching claw 44, and a large number of sheets arranged in a vertical direction and rising upward in the lower path by the switching claw 44 (in the illustrated example, A transfer paper vertical feed path 50 along the transfer paper inlet side of the (20 sheets) bin 49 continues.

At a position corresponding to the entrance of each bin 49 of the transfer paper vertical feed path 50, a pair of rollers of a transport roller 52 and a discharge roller 53 are provided together with a deflection claw 51. Here, a plurality of rollers provided at appropriate intervals in the transport roller 52 are pressed by a driven roller 54 with the transfer paper longitudinal feed path 50 interposed therebetween. Further, a drive motor 55 for driving the transport belts 42, 43 and the rollers 47, 52, 53 is provided.

Further, a shaft provided with two pulleys 56 and 57 is provided at the upper and lower portions of the bin group, respectively, on the sorter unit 4.
And a lower shaft is connected to a motor 58 for moving the post-processing unit. Upper and lower two pairs of pulleys 5
The post-processing unit moving belts 59 are stretched between the belt units 6 and 57, respectively.
0 and a post-processing unit 61 are mounted via a guide unit 62. In order to guide the guide unit 62, a guide rail 63 that extends over almost the entire height of the sorter unit 4 is provided in the vertical direction beside the bin group.

With such a configuration, the transfer paper 12 discharged from the copying machine main body 2 is conveyed to the upper side of the sorter unit 4 while being inserted from the entrance guide plate 41 and sandwiched by the conveyance belts 42 and 43. Here, assuming that the mode is the normal paper discharge mode (that is, the mode 9 in which the paper is discharged to the paper discharge tray 48), since the switching claw 44 is lowered, the transfer paper 12 is discharged along the switching guide plate 46 side. Roller pair 47
Is discharged onto the discharge tray 48. On the other hand, if the mode is a sort mode (a mode in which the bin 49 sorts and discharges pages in order) or a stack mode (a mode in which the bin 49 sorts and discharges page by page), the switching claw 44 is raised and the transfer paper 12 is switched. The paper is conveyed downward along the transfer paper longitudinal feed path 50 along the guide plate 45. The transfer paper 12 transported by the transport roller 52 and the driven roller 54 is
1 is discharged to the bin 49 where it is operating. The deflection claw 51 moves according to the mode (sort or stack).

First, in the sort mode, the first page 1
The deflection claw 51 of the first bin is actuated for the first transfer sheet and ejected to the first bin 49.
The deflection claw 51 of the bin is actuated and ejected to the second bin 49, and the same is repeated for the bins for the number of copy sets. The deflection claw 51 of the first bin operates for the first transfer sheet of the second page and is discharged to the first bin 49, and the deflection claw 51 of the second bin for the second transfer paper. Operates to discharge to the second bin 49, and thereafter, the same is repeated for bins corresponding to the number of copies. In the sort mode, such processing is repeated for each original (each page), and one bin 4
9, the first page copy, the second page copy, the third page copy,
The pages are ejected in the order of pages.

On the other hand, in the stack mode, all copies (transfer paper) of the first page are discharged to the first bin 49, and all copies of the second page are transferred to the second bin 4.
For example, each deflection claw 51 is sequentially operated. Thus, in the stack mode, only copies of the same page are discharged to one bin 49, and the bins are sorted by page.

Next, a post-processing function for performing post-processing on the transfer papers 12 thus sorted will be described. The post-processing unit 61 means a stapler, a puncher, or the like. First, the post-processing unit 61 is connected to each bin 4
9, the post-processing unit motor 58 is rotated, the post-processing unit moving belt 59 is moved up and down via the pulleys 57 and 56, and the guide unit 62 is moved up and down accordingly. Have been. The guide unit 62 has a car, and the guide rail 6
3 is free to move.

The chuck unit 60 is a device for transporting the transfer paper bundle to the position of the post-processing unit 61 and returning it to the original position after the execution of the post-processing. In FIG. 7, the home sensor 65 is turned on by the home detecting piece 64, and the post-processing can be performed on the copy bundle of the first bin. When the post-processing is executed in this state, the post-processing unit 61 is turned on by turning on the post-processing moving motor 58 after the execution.
The bin position sensor 66 is turned on by the position detection piece 64 of the second bin, and the post-processing moving motor 58 is turned off.
The post-processing unit 61 is stopped. Then, post-processing of the copy bundle of the second bin is performed. The same post-processing is repeated, and when the execution of the post-processing for the copy bundle of the predetermined bin is completed, the post-processing unit 61 is returned to the home position. In this way, post-processing of a plurality of copy bundles becomes possible.

Here, FIG. 8 shows a state where FIG. 7 is viewed from the opposite side, and matters that cannot be expressed in FIG. 7 will be described. The sorter unit 4 according to the present embodiment is composed of, for example, 20 bins, and is divided into two blocks of 10 bins each.
8 and paper ejection sensors 69 and 70 are provided, and the bin sensors 71 and 72 and paper ejection sensors 73 and 74 are also provided for the lower block.
Is provided. Discharge sensors 75 and 76 are also provided for the discharge tray 48. These sensors 67-
Reference numeral 76 denotes a transmission type optical detection sensor including a pair of an LED and a phototransistor. Each paper ejection sensor detects whether a copy has been ejected,
Each bin sensor detects whether or not there is a copy in the bin. By using such a bin sensor,
For example, if a copy is placed in the bin of the upper block, it is possible to switch to using the lower block.

By the way, in order to perform post-processing of a copy, the copy bundle must be aligned on the bin 49. For this reason, the sorter unit 4 of the present embodiment is provided with the following jogger. First, the jogger drive belt 83 is rotated by the jogger moving motor 81 via the pulley 82, and the drive shaft 84 is rotated. Accordingly, the upper and lower jogger moving belts 87, 88 move via the pulleys 85, 86, and the shaft fixing unit 89 and the alignment shaft driving unit 90 fixed thereto move. Then, the position of the predetermined size detection piece 91 is detected by the size detection sensor 92, and the jogger drive motor 81 stops.
When the copy is discharged to the bin 49, the discharge sensor 6
The alignment shaft driving unit 90 operates to move the alignment plate 93 by the alignment shaft 94 to align the copy bundle. Then, after the post-processing is completed, the jogger moving motor 81 rotates in the reverse direction, and stops at the position where the home sensor 96 is turned on by the home detection piece 95. This position is also the alignment position for the maximum size. In this way, each time a copy is ejected, it is aligned and prepared for a post-processing operation.

FIG. 9 shows a plan view from the top of FIG.
A notch 49a is formed in the bin 49 so that the alignment shaft 94 can be moved to a position where the minimum size copy alignment is possible. The alignment plate 93 rotates as shown by the arrow to align the copies. At this time, an end face holding plate 97 is provided to set the other end of the copy at a fixed position. The end face holding plate 97 is set so as to move in accordance with the movement of the chuck unit 60.

FIG. 10 is a view of FIG. 7 viewed from the right side, which is moved in the direction of the arrow by the jogger moving belt 88 and can be stopped at the size detecting piece 91 in accordance with each copy size. Further, the rightward movement is set to a position where the home sensor 96 adjusted to the maximum copy size can be operated by the home detection piece 91.

FIG. 11 is a partially cutaway perspective view showing details of the chuck unit. The chuck unit 60 has a function of grasping the copy bundle on the bin 49 and moving it to the post-processing unit 61, and returning to the same state as when it was discharged onto the bin 49 again after the post-processing. First, when the motor 101 rotates in the H direction, the worm gear 102
Rotates, and the gear 103 rotates in the I direction. Then, the spiral shaft 104 rotates, and the moving plate 106, the upper and lower chucks 107 and 108, and the pushing plate 109 move in the B direction via the moving rod 105 having the spiral hole. When moving in the direction B, the home sensor 111 is turned on by the position detecting piece 110 and the motor 101 is stopped.

When the motor 101 is rotated in the G direction, the gear 103 is rotated in the J direction, and the moving rod 105 and the moving plate 1 are rotated.
06, upper and lower chucks 107 and 108 and push plate 109
Moves in the A direction. When the motor moves in the direction A, the home sensor 112 is turned on by the position detecting piece 110 and the motor 10 is turned on.
Stop 1 Then, when the solenoid 113 is turned on, the upper chuck 107 is pulled
Go down and grab the copy bundle. At this time, the end face holding plate 9
7 is lowered in the F direction by the push plate 109, and does not hinder the movement of the copy bundle.

When the motor 101 rotates in the H direction, the copy bundle is brought in the B direction. When the pressing plate 109 returns in the direction B, the end face pressing plate 97 attempts to return to its original state by the coil spring 115, but stops at the position of the copy bundle because the copy bundle is already on the upper side. When the moving plate 106 reaches the home position, the motor 101 is stopped, and thereafter,
The post-processing unit 61 is operated, and after the post-processing is completed, the motor 101 is again rotated in the G direction to return the copy bundle to the A direction. When the position detecting piece 110 turns on the home sensor 112 again, the motor 101 stops, the solenoid 113 turns off, the upper chuck 107 moves up by the coil spring 115, and the copy bundle returns to the original position,
The end face holding plate 97 also returns to the original position. And the motor 10
1 rotates in the H direction, returns the movable plate 106 to the home position, and stops. Thus, the chuck unit 60 carries out the operation of transporting the copy bundle discharged onto the bin 49 to the post-processing device 61 and returning it to the original position.

FIG. 12 shows an example of the configuration of the post-processing unit 61 of the stapler configuration.
6 is turned on, the staples 11 in the cartridge 117 are turned on.
8 to bend. The staples 118 are connected in a strip shape with a thin tape and are rounded in the cartridge 117. Further, when the end of the staple 118 passes through a near-end sensor 119 formed by a reflective optical sensor, a near-end signal is output.

FIG. 13 shows the details of the aligning shaft drive unit 90 shown in FIGS. 8 and 9. When the motor 120 makes one rotation, the aligning plate 93 moves through the cam 121, the lever 122 and the aligning shaft 94 by an arrow. It rotates in a fan shape in the A and B directions.
In this way, each time a copy is discharged to the bin 49, the motor 120 makes one revolution to align the copies.

Here, the limitation of paper alignment by such a jogger operation will be described with reference to FIG. As described above, each bin 49 is formed with the notch 49a which can move the alignment shaft 94 to a position where the minimum size copy can be performed (see FIG. 14A). As shown in FIG. 14B, the alignment shaft 94 has the notch 49a.
The inside is moved to the back to align the paper, and in the case of a copy of a large size, the alignment shaft 94 aligns the paper at an outer position in the notch 49a as shown in FIG. .
Accordingly, in the multi-job mode in which the first and second jobs are continuously performed, the stapling process is performed in both cases, and after the paper alignment and post-processing is performed using the transfer paper 12 having a relatively large size in the first job. If the transfer paper 12 of a smaller size is used in the second job, the movement of the alignment shaft 94 is restricted by the transfer paper 12 of the first job which has been discharged earlier, and therefore the second transfer is performed. It becomes impossible to align the transfer paper 12 by the job. This is because the alignment shaft 94 is not provided for each bin, but is provided commonly for all the bins 49 so as to penetrate vertically. There is no problem if the transfer paper size used in the second job is larger. In the present embodiment, as described later, control is performed in consideration of such points.

FIG. 15 shows the structure of the electric control system. The CPU 130 controls the ROM 131, RAM (which is a non-volatile memory by backup) 132, IN port 133, OUT port 134 and I / O port 135.
Is performed by a microcomputer system configured to be connected to the microcomputer. That is, the ROM 1 in which the program is written
31 and receives various input signals from the IN port 133 while using the RAM 132 as needed.
The controller 4 controls each unit in the copying machine main body 2 and each load in the sorter unit 4. To control the sorter,
Post-processing operations such as stapling operations after copy sorting are also included. The control unit of the ADF 3 is connected to the I / O port 135, and signals are exchanged with the CPU 130. The ADF 3 feeds the document onto the contact glass 9 according to a signal from the CPU 130 and discharges the document after the exposure. In the double-sided document processing mode, the operation is performed such that the sheet is turned over after the exposure of the first side is completed, and the second side is set on the contact glass 9 again.

In such a configuration, the first original bundle P1
The operation control at the time of setting the multi-job mode in which the first job with respect to and the second job with respect to the second bundle of documents P2 are continuously performed will be described with reference to the flowchart shown in FIG. First, it is determined whether or not the multi-job mode has been set on the operation unit. If not, a normal copy operation is performed. When the multi-job mode is set, the copy operation of the first job is performed on the first document bundle P1. When the first job is completed, copy mode information relating to a preset second job is read out, and various determinations are made according to the mode. First, the transfer sheet discharge destination in the copy mode of the preceding first job is not the mode using the bin 49 in the sorter unit 4 (that is, the discharge sheet is simply discharged to the discharge tray 48 without any post-processing). In this case, the copy operation of the second job is executed following the first job as usual.

However, the first job requires post-processing,
If the copy mode with the paper ejection mode using the bin 49 has been set, the copy mode of the second job is checked. First, it is determined whether the staple mode is set as the post-processing mode during the copy mode of the second job. In the case of the staple mode, the size is determined by the comparing means. That is, it is determined whether the transfer paper size used in the second job to be executed is smaller than the transfer paper size already discharged to the bin 49 by the execution of the first job. If the size is small, as described above, the transfer paper of the second job cannot be aligned and stapling cannot be performed normally, so the message "Stapling cannot be performed for the second job" is displayed through the message display unit of the operation unit. A warning is displayed to the effect that processing cannot be performed. This warning display indicated by the step corresponds to the processing of the warning means according to the first aspect of the present invention, and it is possible to prevent a copy accompanied by a stapling operation that cannot be performed normally.

After such a warning, the copying operation of the second job is stopped until the operator performs any operation as shown in steps. This corresponds to the processing of the second job stopping means according to the fourth aspect of the invention corresponding to the first aspect of the invention. Therefore, a response as desired by the operator can be taken. For example, a result with normal stapling for the second job cannot be obtained as it is,
If the second job cancel operation has been performed, it is determined that the second job has ended, and the processing ends. Here, as the second job canceling operation, the mode clear key is pressed, and the second original bundle P
2 may be removed.

On the other hand, if the user wants to execute the second job without canceling it, the staple mode is canceled as the paper ejection mode. The suspension of the two jobs is released, and the second job is executed. The processing shown in this step corresponds to inventions of claims 2, wherein.
In other words, the transfer paper for the second job has been changed to a mode that does not require paper alignment, so there is no problem.

Further, even if the mode is not changed for the second job, the transfer sheet 1 of the first job already discharged can be used.
If it is detected that 2 has been removed from bin 49,
Since the restriction is eliminated, the paper alignment and the normal stapling operation can be performed, so that the stop of the second job is immediately released and the second job is executed. The processing shown in this step corresponds to inventions of claim 1, wherein.

In the case where the copy mode of the second job is the discharge destination mode using the bin 49 and the mode is not the staple mode, it is determined whether the mode is the sort mode or the stack mode. In the case of the sort mode, the sorter unit 4 compares the number of remaining bins not used in the execution of the first job with the number of sets set in the sort mode of the second job, and if the number of remaining bins is sufficient, The second job is executed as it is. In the case of the sort mode involving the staple mode (including the case where the staple mode has been canceled), this determination is received and processed.

However, if the comparison result indicates that the number of remaining bins is insufficient, the sorting process cannot be performed normally. There line displays a warning to the effect that made processing impossible, such as ", it is possible to prevent the copy with the sorting process that can not normally in advance.

After such a warning, the copy operation of the second job is stopped until the operator performs any operation as shown in steps . I, show the correspondence as desired by the operator. For example, since a result with the normal sorting process for the second job cannot be obtained as it is, if the cancel operation of the second job is performed, the end of the second job is determined and the process ends.

On the other hand, even if the mode is not changed for the second job, the transfer sheet 1 of the first job already discharged
If it is detected that 2 has been removed from bin 49,
Since there is no restriction, normal sorting can be performed, so that the suspension of the second job is immediately released and the second job is executed .

The same applies to the case of the stack mode instead of the sort mode. However, in the case of the stack mode, the number of sheets of the second original bundle P2 for the second job is unknown, and the number of remaining bins Because there is no guarantee that the stack can be normally performed without comparing with, immediately without going through the judgment process,
Through the message display section of the operation section, a warning display indicating that processing cannot be performed, such as "stack processing cannot be guaranteed for the second job" or "please remove copy paper from sorter" is performed .

After such a warning, the copying operation of the second job is stopped until the operator performs any operation as shown in steps . I, show the correspondence as desired by the operator. For example, as it is impossible to guarantee a result with the normal stack processing for the second job as it is, if the second job cancel operation is performed, the second job
Judge that the job has ended, and end.

On the other hand, even if the mode is not changed for the second job, the transfer sheet 1 of the first job already discharged
If it is detected that 2 has been removed from bin 49,
Since there is no restriction, normal stack processing becomes possible, so that the stop of the second job is immediately released and the second job is executed .

If the second job cannot be executed in the case where the sort mode or the stack mode is involved, the mode may be canceled and the mode may be changed to a mode in which the sheet is simply discharged to the sheet discharge tray 48. .
