[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet distribution / accommodation device for distributing and accommodating recording sheets discharged from an image recording device such as a copying machine or a printer, and more particularly to stapling after recording and distributing recording sheets. The present invention relates to an improvement in a sheet distribution / accommodation device that enables post-processing such as punching.

[0002]

2. Description of the Related Art In general, as a sheet distributing and accommodating apparatus called a sorter, a sheet conveying path is formed in a housing, and conveying rollers are appropriately arranged along the sheet conveying path. While conveying the recording sheet discharged from the sheet discharge port of the image recording apparatus to a preset sheet distribution stage, on one side of the housing, a plurality of bin trays are disposed in a vertical direction,
In some cases, each bin tray is sequentially moved to the above-mentioned sheet distribution stage in accordance with the distribution timing of recording sheets, and recording sheets are sequentially distributed and accommodated in each bin tray.

[0003] Post-processing such as stapling is often performed on the recording sheets distributed and accommodated in the sorter described above, and a post-processing unit such as a stapler is incorporated in the sorter. There is a request that the processing be performed automatically.

[0004] As a sorter responding to such a request,
For example, those described in JP-A-63-41360 and JP-A-63-252
No. 872, the one in Japanese Patent Publication No. 64-302 is already known.

However, in the former type (JP-A-63-41360), post-processing by a stapler is performed after a recording sheet bundle distributed and stored in a bin tray is stored again in a post-processing tray. Inevitably, a post-processing tray must be provided separately from the bin tray, and transport means for transporting the recording sheet bundle to the post-processing tray must be provided. Not only is the recording sheet bundle complicated, but also when the recording sheet bundle is transferred to the post-processing tray side, the recording sheet bundle once aligned in the bin tray may vary, and post-processing by the stapler tends to be useless. There was a problem.

The latter (Japanese Patent Application Laid-Open No. 63-252872,
No. 64-302), a stapler is provided near the sheet distribution stage that does not interfere with the sheet transport member, and post-processing by the stapler is performed on the bundle of recording sheets stored in the bin tray (stored in the bin tray). Stapling processing at one corner of the recording sheet bundle), so that the technical problem of the former type can be avoided, but one side edge of the recording sheet bundle is formed at two positions. However, there is a problem that dual stapling processing of stapling cannot be performed.

For this reason, the inventors of the present application have previously proposed a sheet distribution and accommodation device having the following configuration.

That is, the sheet conveying means is disposed in the housing and conveys the recording sheet discharged from the sheet discharge port of the image recording apparatus to a preset sheet distribution stage, and a plurality of sheet conveying means are arranged vertically on one side of the housing. A bin tray that is arranged in stages and sequentially moves to the sheet distribution stage according to the distribution timing of the recording sheets, and a space inside the housing that is located below or above the sheet conveying means and extends in the width direction of the sheet conveying means. One post-processing unit provided, position moving means for movably supporting the post-processing unit at least across the width direction of the sheet conveying means, and a predetermined post-processing stage different from the sheet distribution stage. After setting the above-mentioned post-processing unit to the post-processing target position, set it on one side edge of the recording sheet in each bin tray. Cormorant a sheet distribution and storage apparatus having a post-processing control means for sequentially perform a predetermined post-processing by the post-processing unit to a plurality of locations.

As described above, as a configuration for moving the post-processing unit, post-processing (such as stapling processing) is performed on a plurality of locations along one side edge of the recording sheet bundle stored in the bin tray. Is made possible.

The post-processing mode in the sheet distributing and storing apparatus having such a configuration is a corner mode in which post-processing is performed at one corner on one side, which is a reference for alignment of recording sheets in a bin tray. It is possible to set a single mode in which post-processing is performed on one corner on the side opposite to the one side, a dual mode in which post-processing is performed on two intermediate portions of the recording sheet, and the like.

In the corner mode, the size (..., A4 size, B5 size,...) And posture (vertical orientation,
Regardless of the landscape orientation, post-processing can be performed by moving and setting the post-processing unit to a specific location. In the single mode, dual mode, etc., post-processing is performed depending on the size and orientation of the recording sheet. The position where the unit should be moved is different.

Therefore, the size, posture, mode (corner, single, dual, etc.) of the recording sheet are displayed on the operation panel.
A plurality of post-processing selection switches are appropriately combined, and the operator or the like presses and selects one of them, and the post-processing unit is moved and set to a position corresponding to this so that a predetermined post-processing is performed. Was there.

[0013]

However, there are many combinations of recording sheet sizes, postures and modes.
Therefore, since the number of post-processing selection switches also increases,
There is a problem that operability is poor for operators and the like. Further, since there are many post-processing selection switches, there is a problem that the wrong post-processing selection switch is often pressed, and post-processing is often performed at an unplanned position. .

The present invention has been made in view of the above point, and when the post-processing which does not match the size or the posture of the recording sheet to be post-processed is selected, the post-processing is not performed. The purpose of the present invention is to provide a sheet distribution and accommodation device.

[0015]

For example, as shown in FIG. 1, a recording sheet 4 disposed in a housing 1 and discharged from a sheet discharge port 3 of an image recording apparatus 2 is set to a preset sheet distribution stage. Sheet transporting means 5 for transporting the sheet to S1, a bin tray 6 which is arranged in a plurality of stages vertically in one side of the housing 1 and sequentially moves to the sheet distribution stage S1 according to the distribution timing of the recording sheets 4;
One post-processing unit 7 located below or above the sheet conveying means 5 and disposed in the space inside the housing 1 across the width direction of the sheet conveying means 5; After moving and setting the post-processing unit 7 to a predetermined post-processing target position at a position moving unit 8 that movably supports the post-processing unit 7 and a post-processing stage S2 different from the sheet distribution stage S1. And a post-processing control unit 9 for sequentially performing predetermined post-processing by the post-processing unit 7 on a portion along one side edge of the recording sheet 4 in each bin tray 6.

Then, the size, posture, and post-processing mode of the recording sheet 4 (a corner mode in which post-processing is performed on a corner of the bin tray 6 that serves as a reference for aligning the recording sheets 4 in the width direction, the recording sheet). 4) a combination of a single mode in which post-processing is performed on the corner opposite to the reference side of alignment and a dual mode in which post-processing is performed at two positions in the middle of the recording sheet 4). A plurality of post-processing selection means (switches) 9b for
Before or after the distribution / accommodation processing of 1, the movement and operation of the post-processing unit 7 by the post-processing control means 9 is controlled based on the setting of the post-processing selection means 9b selected by the operator.

Further, size detecting means 9a for detecting the size and orientation of the target recording sheet 4 is provided, and the size and orientation of the recording sheet 4 selected by the post-processing selecting means 9b are detected by the size detecting means 9a. When the size and orientation of the recording sheet 4 are not suitable, the fact that the selection is incorrect is displayed on the operation panel without performing the post-processing. The size detecting means 9a
Can be provided near the conveyance path of the recording sheet 4. Further, a signal from a size detecting means provided in the image recording apparatus 2 may be used together.

As a concrete configuration of the plurality of post-processing selecting means 9b and means for displaying a predetermined message, for example, as shown in FIG. 2A, a corner mode,
A4 single mode, B5 single mode, A3 / B4
/ A4 horizontal / B5 horizontal dual mode selection switches 9c and indicator lights 9d that are lit when the selection switches 9c are pressed are provided correspondingly.
A message display device 9e may be provided adjacent to them to configure the device. Further, as another specific configuration, FIG.
As shown in (B), an indicator lamp 9f is provided which is lit according to the size and posture of the recording sheet 4 detected by the switch 9c and the size detecting means 9a similar to the above, and the indicator lamp 9f is lit. It is possible to perform the post-processing only when the existing switch 9c is pressed and not perform the post-processing even if the switch 9c whose indicator lamp 9f is not lit is pressed. In this case, even if a message to that effect is displayed,
You don't have to.

[0019]

When the post-processing is continuously carried out after the distribution / accommodation processing of the recording sheet 4, the post-processing is carried out before the distribution / accommodation processing or after the distribution / accommodation processing is instructed by the operator. After the distribution / accommodation processing is performed, the operator or the like appropriately presses and selects the selection switch 9c provided on the operation panel. If the operator or the like selects the wrong selection switch 9c by pressing it, the post-processing control means 9 makes an error in the selection by the selection switch 9c from the size and orientation of the target recording sheet detected by the size detection means 9a. The message indicating that is displayed on the message display 9e on the operation panel without performing post-processing.

In this way, when the operator or the like selects the post-processing that does not match the size and orientation of the target recording sheet 4, the post-processing is not performed and the fact that the selection is incorrect is displayed. As a result, the operator or the like can recognize that there is an error in the selection and can select an appropriate post-process. A specific example of the message displayed on the display 9e in this case may be a message such as "post-processing cannot be performed at the designated position, please change the designated position".

III. Operation of the Apparatus (1) Sorting Processing Outline of Processing It is assumed that the copying machine body 10 has been operated to copy a predetermined number of originals one by one using the ADF and sort the originals.

At this time, a sorting selection signal is taken into the CPU 171 from the main body side CPU 176, and the sorting processing program is executed.

Then, first, the switching gate 38 selects the first sheet conveying path 32 by driving the solenoid 184, and the conveying rollers 34 and 35 and the discharging rollers 36 and 37 are driven by driving the feed motor 183. You. In this state, the recording sheet 12 discharged from the sheet discharge port 11 of the copying machine main body 10 is sequentially conveyed from the common sheet conveying path 31 to the sheet distribution stage S1 through the first sheet conveying path 32. It is sequentially distributed and accommodated in the bin tray 40 that moves sequentially to S1.

FIG. 19 shows a flow of controlling the movement of the bin tray 40 during the sorting process.

In the figure, when copying is started on the body 10 side of the copying machine, the CPU 171 first detects the size and orientation of the recording sheet 12 (step [hereinafter S
Abbreviated as T] 1a). In the case of this embodiment, the CPU 176 on the main body side of the copying machine detects the size and orientation of the original, and the CPU 171 receives these information from the CPU 176 on the main body side. Then, the post-processing selection switch 18
The setting of 2 is detected (ST1b), and it is determined whether or not the size and orientation assigned to the selection switch 182 detected in ST1b match the size and orientation of the recording sheet 12 detected in ST1a (ST1b).
c). That is, it is determined whether or not the size and orientation (there are a plurality of cases) assigned to the selected selection switch 182 and the detected size and orientation. ST1c
If the automatic reservation for stapling is not made, the automatic reservation is canceled (ST1d) if the automatic reservation is made (ST1d).
e), the fact that the reservation has been canceled is displayed on the operation panel (S).
T1f). The automatic reservation for stapling is set by the operator before the start of copying.
It is set to automatically perform post-processing after the completion of copying without any special operation.

If the size and orientation are matched in ST1c, if the automatic stapling reservation is not made in ST1d, or if the processing in ST1f is completed, the CPU 171 causes the sheet exit sensor 3
When 8 changes from ON to OFF, the bin drive motor 58
Each bin tray 40 is moved up by one pitch (ST1, 2) by unit driving, and it is checked whether or not the final copy of the job, that is, the copy job of each page of the original document is completed (ST3).

Next, when the final copy of the job is not completed, the processing from ST1 to ST3 is repeated,
At the stage where the final copy of the job has been completed, it is checked whether or not all jobs, that is, the copy job of the entire document has been completed (ST4).

Further, when all the jobs are not completed, each bin tray 40 is lowered by one pitch by driving the bin drive motor 58 as a unit when the sheet exit sensor 38 changes from ON to OFF ( ST5
6) It is checked whether the final copy of the job has been completed (ST7).

When the final copy of the job is not completed, the processing from ST5 to ST7 is repeated,
At the stage where the final copy of the job has been completed, it is checked whether or not the bin home sensor (corresponding to the lower limit position detection sensor 66) has been turned on (ST8), and then it is checked whether or not all the jobs have been completed (ST9). . At this time, ST9
If it is determined that all the jobs have not been completed, the process returns to ST1 to perform a series of subsequent processes.

When it is determined in ST4 or ST9 that all jobs have been completed in the above process,
A series of sorting processing ends.

In ST8, the bin home sensor 6
If it is determined that No. 6 is not turned on, a FAIL display is performed (ST10).

Tamper Movement Control FIG. 20 shows a movement control flow of the tamper 71 during the sorting process.

In the figure, the CPU 171 is the main unit C
The size information of the recording sheet 12 is fetched from the PU 176 (ST1), and the tamper drive motor 80 is driven to rotate forward in accordance with the motor signal (RA area) shown in FIG. Of the tamper 71 is set to the reference position for each size (a position slightly larger than the storage position of the recording sheet 12) indicated by the alternate long and short dash line (ST2).

Thereafter, the number of discharged sheets of the recording sheet 12 is counted by counting the ON → OFF signal of the sheet discharge sensor 38 (ST3), and the final copy of the job, that is, the copy job of each page of the original document is completed. If it is judged that the final copy of the job is not completed (ST4), the processes of ST3 and ST4 are repeated.

When it is judged in ST4 that the final copy of the job is completed, the tamper drive motor 80 is rotated in the predetermined range in accordance with the motor signal (R2 region) shown in FIG. As shown in FIG. 22, the tamper 7 located at the size-based reference position indicated by the solid line
1 is moved to the edge position of the recording sheet 12 (indicated by a dashed line), the recording sheet 12 is pressed against the positioning wall 48, aligned, and then returned to the size-specific reference position (ST).
5).

Thereafter, it is checked whether or not all copy jobs are completed (ST6), and if it is determined that all copy jobs are not completed, the processes from ST3 to ST6 are repeated.

Then, in ST6, when it is determined that the all copy job is completed, the tamper drive motor 80 is reversely driven in accordance with the motor signal (R3 region) shown in FIG. As described above, the tamper 71 positioned at the size-based reference position indicated by the solid line is returned to the home position indicated by the chain double-dashed line (ST7), and at this stage, the tamper operation during the sorting process is completed.
It is determined whether the tamper home sensor 78 has returned to the home position by changing the tamper home sensor 78 from a low level to a high level signal, as shown in FIG.
