The present invention relates to a sheet dispensing accommodating apparatus for distributing and accommodating recording sheets discharged from an image recording apparatus such as a copying machine or a printer. In particular, the sheet dispensing accommodating sheet enables post-processing such as stapling after dispensing and accommodating the recording sheets. It relates to the improvement of the device.

As a sheet dispensing device generally called a sorter, a sheet conveying path is formed in the housing, and the conveying rollers are appropriately disposed along the sheet conveying path, and the recording sheet discharged from the sheet discharge port of the image recording apparatus such as a copying machine or a printer is preliminary. The sheet dispensing stage is conveyed to the sheet dispensing stage set in the above, while a plurality of bin trays are arranged on one side of the housing in the vertical direction, and the bins are sequentially moved to the sheet dispensing stage according to the dispensing timing of the recording sheets. It is intended to accommodate sequential distribution. In addition, there are many cases where post-processing such as stapling is often performed on the recording sheets distributed and received by the above-described sorter, and there is a request that a post-processing unit such as a stapler is installed in the sorter to automatically perform post-processing in the sorter. .

As a sorter in response to such a request, one described in Japanese Patent Application Laid-Open No. 63-41360, one described in Japanese Patent Application Laid-Open No. 63-252872, and Japanese Theater Special Publication 64-302.

However, in the former type (Japanese Patent Laid-Open No. 63-41360), the stack of recording sheets dispensed and accommodated in the bin tray is stored in the post-processing tray and then post-processed by a stapler, which is inevitably necessary for post-processing separately from the bin tray. A tray and a conveying means for conveying a stack of recording sheets to a post-processing tray must be provided, which not only complicates the arrangement of the heater, but also transfers the stack of recording sheets to the post-processing tray side. As a result, there is a risk that the pile of recording sheets matched once may be broken, and post-processing by a stapler is likely to be wasteful.

In the latter type (Japanese Patent Laid-Open Nos. 63-252872 and 64-302), a stapler is placed near the sheet dispensing stage that is not interfered by the sheet conveying member, and is placed in a stack of sheets on the stack of sheets while being housed in an empty tray. Post-processing (stapling processing for one corner of the recording sheet pile accommodated in the empty tray), so that the technical problem of the former type can be avoided, but one edge of the recording sheet pile is stapled at two places. Ringing has a technical problem that dual stapling processing cannot be performed.

In addition, since either type of the former or the latter only targets one post-process, a plurality of continuous post-processes cannot be performed, and thus the post-processing range has its own limitations.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above technical problem, and a plurality of posts can be provided at any point along one edge of a recording sheet pile, while avoiding the complexity of the device configuration and the deterioration in post-processing quality due to post-processing units such as staplers. It is to provide a sheet dispensing receiving device which enables a plurality of post-processing by a processing unit.

That is, in the first invention, for example, as shown in FIG. 1A, the recording sheet 4 disposed in the housing 1 and discharged from the sheet discharge port 3 of the image recording apparatus 2 is set in advance. The sheet conveying means 5 conveying to the sheet dispensing stage E and the housing 1 are arranged in multiple stages in the vertical direction and sequentially moved to the sheet distributing stage E in accordance with the dispensing timing of the recording sheet 4. A sheet dispensing receiving device having a bin tray 6 for dispensing and accommodating the recording sheet 4 sequentially in each bin tray 6, and located at the lower or upper portion of the sheet conveying means 5, Post-processing unit 7 (specifically, two systems of mutually correlated, for example, two systems, which are selectively disposed at the post-processing set position W of the space in the housing 1 over the width direction of the conveying means 5 (specifically 7a, 7b) at the post-processing set position (W) and this post-processing set position (W) Unit retreat means 8 (specifically 8a, 8b) for supporting the retreat of the post-treatment unit 7 between the retreat positions and the post-treatment unit 7 (specifically, at the time when the sheet dispensing receiving operation is completed) Sets any one of 7a, 7b to the post-processing set position W, and each bin tray at the post-distribution stage E corresponding to the post-processing set position W and the other post-processing stage F. Post-processing control means for causing predetermined post-processing by the post-processing unit 7 (specifically, 7a, 7b) to be sequentially performed at a position along one edge of the recording sheet 4 in the state of dispensing and receiving in (6) ( And 9).

In the second invention, as shown in FIG. 1 (b), the sheet conveying means is constructed on the premise of a sheet dispensing receiving device having the sheet conveying means 5 and the bin tray 6 as in the first invention. A plurality of interconnected post-processing units 7 (specifically 7a, located at the lower or upper portion of 5) and disposed at the post-processing set position W of the space in the housing over the width direction of the sheet conveying means 5; 7b) and a recording sheet in a state in which the sheet dispensing stage E and the post-processing stage F corresponding to the post-processing set position W and the post-processing stage F corresponding to the post-processing set position W are distributed and accommodated in each bin tray 6. It is characterized by including post-processing control means 10 which causes predetermined post-processing by each post-processing unit 7 to be sequentially performed at a portion along one edge of (4).

In the third invention, as shown in FIG. 1 (c), the sheet conveying means is constructed on the premise of a sheet distributing receiving device having the sheet conveying means 5 and the bin tray 6 as in the first invention. 5, a plurality of spaces in the housing 1, for example, two post-processing set positions W (specifically W1, W2), which are located at the lower or upper portion of the sheet conveying means 5 and in the width direction of the sheet conveying means 5; The sheet dispensing stage E corresponding to the plurality of post-processing set positions W at the time point when the sheet dispensing operation is completed and the plurality of post-processing units 7 (specifically, 7a, 7b) to be mutually disposed are completed. ) And a plurality of post-processing stages F (specifically, F1 and F2), respectively, for a portion along one edge of the recording sheet 4 in a state of being distributed and accommodated in each bin tray 6, respectively. Having post-processing control means (11) for sequentially performing predetermined post-processing by 7) It is characterized.

In this technical means, as long as the sheet conveying means 5 can convey the recording sheet 4 to the sheet distributing stage E, the design of the enemy may be changed. In this case, in view of facilitating the handling of the discharge recording sheet 4 when the sorting process is unnecessary, a sheet receiving tray is provided separately from the bin tray 6, and the recording sheet 4 is accommodated on the sheet receiving tray side. It is desirable to design to.

The number of the bin trays 6 can be selected according to the necessary sorting ability, and the configuration of the bin trays 6 is set in a state where the discharged recording sheet 4 is positioned at a predetermined position. It may be necessary to be accommodated, and the design of the bin tray 6 may be appropriately modified, such as forming a positioning flange therein or using a vertical wall or the like of the housing housing 1 as the alignment portion. In order to align the recording sheet 4 accommodated in the bin tray at a predetermined position, it is preferable to design the sheet sorting means in which the recording sheet 4 is aligned at the alignment portion at every predetermined timing.

As for the conveying means of the bin tray 6, if the bin tray 6 is sequentially moved to the sheet dispensing stage E, the design of the enemy may be changed, but the height dimension of the socket housing 1 is shortened. From the point of view, it is preferable to set the gap between each bin tray 6 as narrow as possible in the range which does not interfere with the sorting process and the post-process. In addition, the operation of the bin tray 6 during the sorting process returns to the initial position at the stage where the final bin tray 6, which is sequentially moved by one pitch only in either the upper or lower direction, is distributed, and the pitch is moved again. It is preferable that the bin tray 6 be pitch-moved in any of the up and down directions in consideration of the efficiency of the sorting process.

The post-processing stage F may be at least a different location from the sheet distributing stage E. However, the post-processing stage is considered from the viewpoint of avoiding wasteful movement of the bin tray 6 when transitioning from the sorting process to the post-processing. It is preferable to arrange | position (F) and sheet | seat distribution stage E near.

If the post-processing unit 7 can perform post-processing for one edge of the recording sheet 4 and each post-process is correlated with each other, a stapler, a puncher, a binder, and the like are appropriately selected and combined. You can.

In this case, when the post-processing unit 7 is not executed, the post-treatment unit 7 retreats to a retracted position which is not interfered with the vertical movement of the bin tray 6, and when the post-treatment is executed, it proceeds to the post-treatment execution position, or The bin tray 6 is fixedly disposed at a position that is not interfered with the vertical movement of the bin tray 6, and during the post-processing, the target bin tray 6 in the post-processing stage F is advanced to the post-processing unit 7 side. It is possible to change the design of the enemy, such as designing to realize the processing.

In the former type, it is necessary to design the post-treatment unit 7 and the target bin 6 in the post-processing stage F, which have advanced to the post-treatment execution position at the time of post-processing, so as not to interfere. For example, in a type in which a cutout is formed in the bin tray 6 corresponding to the post-processing execution position, or in which the gap between the bin trays is set as narrow as possible, the object of the bin tray 6 is studied by studying the moving means of the bin tray 6. It is possible to select an enemy such as to enlarge the gap between the bin tray 6 and the bin trays 6 above and below.

In the latter type, it is necessary to design so as not to damage the mating state of the recording sheets 4 accommodated in the bin tray 6. As a specific means thereof, for example, the bin tray 6 has a double structure and a post-processing stage. Withdrawal support means provided in (F) allows the upper tray to be drawn out to the post-processing unit 7 side and post-processed on the recording sheet 4 held in the upper tray or stretched to the post-processing unit 7 side. An optional gripper can be placed and the recording sheet 4 in the target bin tray 6 can be taken out to the post-processing unit 7 by the gripper, and then the post-processing can be performed on the recording sheet 4.

In addition, as the post-processing unit 7, one having a single processing function is usually used. In this type, when there are a plurality of post-processing target positions, the post-processing unit 7 equipped with a single processing function at each post-processing target position can be installed separately, but the compactness of the device or the post-processing target position Is changed by the size of the recording sheet 12 or the like, it is preferable to design the post-processing unit 7 of the single-processing function partly to be used for each post-processing target position. In addition, when the relative positional relationship of a plurality of post-processing positions is invariant, a plurality of processing function units corresponding to each post-processing target position may be provided. As a post-processing by the post-processing unit 7, all the bin trays subjected to the sorting process are performed without any problems, but the post-processing unit 7 when the recording sheet 4 is extracted from the bin tray 6 From the viewpoint of eliminating the wasteful post-processing operation by the apparatus, it is preferable to design the sheet presence detecting means for attaching the post-processing unit 7 to detect whether or not the recording sheet 4 exists in the target bin tray 6. Do.

The unit advancing means 8 may be separately provided for each post-treatment unit 7, or may be designed to be common to each post-treatment unit 7, but at least each post-treatment unit 7 is a post-processing set. It is necessary to design so as not to interfere with each other under the situation set at the position W or the advance position.

In addition, the post-processing control means 9 to 11 perform predetermined post-processing by each post-processing unit 7, and set any post-processing unit 7 to a post-processing possible state and at the same time the target bin tray 6 Is sequentially set to the post-processing stage F, and then only the post-processing unit 7 or the post-processing unit 7 and the mechanisms accompanying it (bin tray take-out means or the like in the bin tray movable type) are controlled.

In this case, the post-processing of the predetermined post-processing unit 7 may be continuously performed for all the bin trays 6, or the post-processing of each post-processing unit 7 may be performed for each target bin tray. none.

Here, each control function of the post-processing control means 9 to 11 can be appropriately selected corresponding to the function to be realized and decremented.

For example, for the position control of the post-processing unit 7, for example, the post-processing unit 7 is stopped at a predetermined post-processing target position based on the information from the position detection sensor, or the recording sheet for the sorting process ( According to the size of 4), the amount of movement from the reference position of the post-processing unit 7 can be determined and the post-processing unit 7 can be moved as much as the calculated amount of movement.

For the processing control of the post-processing unit 7, in the case where the image recording apparatus is a copying machine equipped with an ADF (Auto Document Feeder), in the ADF use mode, the post-processing unit ( In the type in which post-processing by 7) is started or in which a sheet presence detecting means is provided in the post-processing unit 7, when the sheet presence detecting means detects that the recording sheet 4 does not exist, recording in the target bin tray is performed. Cancel the post-processing operation on the sheet 4 and immediately move the next target bin tray 6 to the post-processing stage F, or post-process the post-processing unit 7 at a plurality of post-processing target positions. In the type in which the processing unit 7 is set to move and post-processing is performed at each post-processing target position, the post-processing unit 7 is set to move to the post-processing target position for each bin tray 6. The recording sheet accommodated in each bin tray 6 at the post-processing target position in the step of moving and setting the post-processing unit 7 to one post-processing target position in consideration of post-processing or efficiency of operation. It is possible to select appropriately such that the predetermined post-processing is performed continuously in 4).

The operation of the technical means as described above will be described below. In addition, in the following operation description, it demonstrates that post-processing by two post-processing units 7 (7a, 7b) is performed.

First, in the invention shown in FIG. 1 (a), the recording sheet 4 discharged from the image recording apparatus 2 is sequentially conveyed to the sheet distribution stage E through the sheet conveying means 5, and each bin tray 6 Are sequentially distributed.

After the sorting processing of the recording sheet 4 is completed, the post-processing control means 9 sets the post-processing unit 7a to the post-processing set position W as the unit retreat means 8a. The post-processing by the post-processing unit 7a is carried out by the post-processing unit 7a at the post-processing target point corresponding to one edge of the recording sheet 4 in a state of setting 6 to the post-processing stage F sequentially. Sequentially execute

The post-treatment control means 9 then retracts the post-treatment unit 7a to the retracted position by the unit retreat means 8a and moves the post-treatment unit 7b to the post-treatment set position W by the unit retreat means 8b. The post processing unit is set at the post-processing target point corresponding to one edge of the recording sheet 4 in a state accommodated in the target bin tray 6 after the target bin tray 6 is sequentially set after setting to. Post-processing according to (7b) is executed in sequence.

In the invention shown in FIG. 1 (b), the post-processing control means 10 is arranged at the post-processing set position W after the sorting process as shown in FIG. 1 (a) is performed. 7b) is selected at the same time, and the target bin tray 6 is sequentially set to the post-processing stage F, and the post-processing target point corresponding to one edge of the recording sheet 4 in the state accommodated in the target bin tray 6 is selected. Post-processing by the post-processing units 7a and 7b is executed in sequence.

In addition, in the invention shown in FIG. 1 (c), the post-processing control means 11 is arranged at the post-processing set position W1 after the sorting process as shown in FIG. 1 (a) is performed. After selecting and sequentially setting the target bin tray 6 to the post-processing stage F1, the post-processing unit at the post-processing target point corresponding to one edge of the recording sheet 4 in the state accommodated in the target bin tray 6 is selected. Post-processing according to (7a) is executed in sequence. Subsequently, the post-processing unit 7b disposed at the post-processing set position W2 is selected, and the target bin tray 6 is sequentially set in the post-processing stage F2, and then in the state accommodated in the target bin tray 6. The post-processing by the post-processing unit 7b is sequentially performed at the post-processing target portion along one edge of the recording sheet 4.

III. Operation of the device

In this embodiment, a series of processes are performed in accordance with the mode selected by the mode selection switch 182.

In the following description, the stapling processing + binding processing mode is selected and the dual stapling processing mode is selected as the stapling processing.

(1) sorting

◎ Summary of processing

It is now assumed that the copier main body 15 has been manipulated to copy a predetermined sheet of paper using the ADF and sort it.

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

First, the switching gate 39 selects the first sheet conveying path 32 by driving the solenoid 184, and then the conveying rollers 34 and 35 and the discharge rollers by driving the feed motor 183. 36,37 are driven. In this state, the recording sheet 12 discharged from the sheet discharge port 16 of the copier main body 15 is transferred from the common sheet transfer path 31 to the sheet distribution stage E through the first sheet transfer path 32. It is sequentially distributed and accommodated in the bin tray 40 which is sequentially transported and sequentially moves to the sheet distribution stage E. FIG.

◎ Bin tray movement control

The movement control flow of the bin tray 40 in the sorting process is shown in FIG.

After the copying is performed on the copier main body 15 side in the same figure, the CPU 171 drives each bin tray 40 by driving the empty drive motor 58 in a step in which the sheet exit sensor 38 is changed from ON to OFF. The pitch is increased by one pitch (steps (hereinafter abbreviated as ST) 1,2), and it is checked whether or not the final copy of the narrow, that is, the copy narrow of each page unit of the original is finished (ST 3).

Next, when the narrow final copy is not finished, the process from ST 1 to ST 3 is repeated, and it is checked whether or not the narrow final copy has been completed, that is, the copy narrow of the entire document is finished (ST 4).

In addition, when the full width is not finished, each bin tray 40 is lowered by one pitch by driving the empty drive motor 58 at the stage where the sheet outlet sensor 38 changes from ON to OFF (ST 5, 6). Check whether the final narrow copy is completed (ST 7).

If the narrow final copy has not been completed, the processing from ST 5 to ST 7 is repeated and the empty home sensor (corresponding to the lower limit position detection sensor 66) is turned on at the stage of narrow final copy. Is checked (ST 8), and it is checked whether or not the whole narrow is finished (ST 9).

If it is determined at this time that the narrow width has not been completed in ST 9, the process returns to ST 1 again and subsequent processing is performed.

If it is determined in this processing that the narrowing is completed in ST 4 or ST 9, the series of sorting processing ends.

If it is determined in ST 8 that the vacant groove sensor 66 is not ON, FAIL is displayed (ST 10).

◎ Tamper movement control

In the figure, the CPU 171 receives the size information of the recording sheet 12 from the main body side CPU 176 (ST 1).

The tamper drive motor 80 is rotated forward in response to the motor signal (region R1) shown in FIG. 21, and one point of tamper 71 positioned at the home position of the solid line is cut off as shown in FIG. The movement is set to the reference position for each line size (position slightly larger than the storage position of the recording sheet 12) (ST 2).

Thereafter, by counting the on-off signal of the sheet discharge sensor 38, the number of discharges of the recording sheet 12 is counted (ST3), and it is checked whether the final copy of the narrow, i.e., the copy narrow of each page unit of the original is finished. (ST 4), if it is determined that the narrow final copy has not been completed, the processes of ST 3 and ST 4 are repeated.

When it is determined in ST 4 that the narrow final copy has been completed, the tamper drive motor 80 is rotated forward and backward within a predetermined range in response to the motor signal (region R2) shown in FIG. 21, as shown in FIG. 20 (b). Similarly, the tamper 71 located at the reference position for each solid line size is moved to the edge of the recording sheet 12 (indicated by the dashed-dotted line) to push the recording sheet 12 against the alignment wall 48. After aligning, it returns to the existing position by size again (ST 5).

Thereafter, it is checked whether or not all copy narrows have been completed (ST 6). When it is determined that all copy narrows have not been completed, the processes from ST 3 to ST 6 are repeated.

When it is determined in ST 6 that the entire copy narrow is completed, the tamper drive motor 80 is driven in reverse rotation in response to the motor signal (region R3) shown in FIG. 21 to show the solid line as shown in FIG. 20 (b). The tamper 71 located in the reference position for each size is moved back to the home position of the two-dot chain line (ST 7). In this step, the tamper operation during the sorting process is terminated. In addition, it is judged whether the tamper groove sensor 78 is changed from the low level to the high level signal as shown in FIG.

◎ Specific example of sorting treatment (refer to FIG. 22)

Now suppose you use the ADF to copy K originals by n and sort them.

At this time, as shown in Fig. 22 (a), first, the original copy recording sheet 12 (1) is distributed and accommodated in the uppermost bin tray 40 (1) located in the sheet distribution stage E. Subsequently, as shown in Figs. 22B and 22C, the second tray bin 40 (2) is set in the sheet distribution stage E, and then the recording sheet (2) is written to the bin tray 40 (2). 12 (1) is distributed and received, and the recording sheet 12 (1) is sequentially distributed in the bin trays 40 (3) ... 40 (n) from the third to the nth stage.

Next, when the copying operation of the second original is started, the second original copy recording sheet 12 (2) is conveyed to the sheet distribution stage E in sequence. Then, as shown in Fig. 22 (d), the recording sheet 12 (2) is first distributed and received in the n-th bin bin 40 (n) positioned in the sheet distributing stage E. a) As shown in (f), after the n-th bin bin 40 (n-1) is set in the sheet distribution stage E, the sheet is written to this bin tray 40 (n-1). 12 (2)) is distributed and thereafter, the recording sheet 12 (2) is sequentially distributed in the bin trays 40 (n-2) ... 40 (1) from the n-th to the top-most stages.

Thereafter, the same operation is repeated until the K-th copy of the document is finished.

In such a series of copy narrows, the tamper 71 is set at the reference position for each size at the start of copying as shown in Figs. 22 (a) to (f), and the document copy widths are sequentially set from the first sheet. At the end of each time, the recording sheet 12 is aligned by moving up to the position of the edge of the recording sheet 12 in each bin tray 40.

Thereafter, it is checked whether or not stapling processing is required in response to the output of the first sheet presence detector 160 (ST 5), and when it is determined that stapling processing is necessary, the bin tray 40 is moved downward by one pitch. Then, the bin tray 40 is set at the initial stapling position so that the uppermost bin tray 40 or the single bin bin 40 corresponding to the number of sorting water is positioned at the post-processing stage F (ST 6).

After that, it is checked whether the stapling mode is the dual mode according to the information from the mode selection switch 182 of the stapling mode (ST 7), and if the dual mode, the dual stapling process is executed (ST 8), while the dual If not in the mode, it is determined that the corner mode is executed and corner stapling processing is executed (ST 9).

(ST 10), if it is determined that the binding process is necessary, the process proceeds to the binding process (ST 11). On the other hand, if it is determined that the binding mechanism is not necessary, the movable motor 131 is moved by reverse driving the driving motor 135 in preparation for the next sorting process, and the driving motor (according to the information from the position detection sensor 146) is moved. 135 is stopped to return the stapler 100 to the corner stapling position P0 (in this embodiment, the initial position) (ST 12) and the upper bin tray 40 is placed on the sheet dispensing stage E.

The process up to ST 8 is repeated.

If it is determined in ST 7 that the stapling target is the final bin tray 40, it is determined that the stapling process is completed in this step (ST 9).

◎ Corner stapling

An example of the ST 9 process of FIG. 23 is shown in FIG. 24 (b).

Each bin tray 40 is moved downward by one pitch for stapling the recording sheets 12 of each bin tray 40 (n) to 40 (1) sequentially, and then the stapler 100 is placed in the dual stapling position. After setting to (P1), each bin tray 40 is moved up by one pitch for stapling the recording sheets 12 of the bin trays 40 (n) to 40 (1) sequentially.

(3) binding processing

◎ Basic binding control

27 shows the basic control flow of the bin tray 40 and the binder 200 during the binding process.

When the CPU 171 determines that the binding processing is necessary in the same figure, the CPU 171 first rotates the drive motor 135 forwardly to the enemy, thereby retracting the stapler 100 disposed at the dual stapling position P2. (Q 1), and then the drive motor 224 for lifting and lowering is forwardly rotated to raise the binder 200 to the upper stop position, thereby setting the binder 200 at the post-treatment set position W ( ST 2). The bin tray 40 is set at the binding initial position so that the single bin tray 40 corresponding to the small number of water during the movement is positioned at the post-processing stage F (ST 3).

In this step, the binding basic operation is performed (ST 4) and the binding target is checked whether the final bin tray 40 is used (ST 5). If the final bin tray 40 is not the final bin tray 40, only one pitch is lowered. Next, the bin tray 40 to be bound is set in the post-processing stage F (ST 6), and the processes of ST 4 to ST 6 are repeated until the binding target is the final bin tray 40.

Then, it is determined that the binding process is completed at the stage where the binding process for the final bin tray 40 is finished (ST 7), and then prepares for the next sorting process.

That is, the binder 200 is retracted to the retracted position (lower stop position) by first rotating the elevating drive motor 224 (ST 8), and then the stapler 200 is moved to the corner stapling position P0 (initial position). The bin tray 40 is returned to the initial position for sorting (ST 9).

◎ Basic binding process

The binding basic operation process is performed as follows.

Specifically, as shown in FIG. 28 (a), the CPU 171 first records the recording sheet corresponding to the cutouts 44 and 45 of the bin tray 40 by the belt gripper 201 being recapped from the standing state. 12) After moving the target bin tray 40 by 1/2 pitch in this step, the stack of the recording sheet 12 is pulled out by the belt gripper 201, and the recording sheet 12 is fed by the feed roller 205. The pile is pushed to the tape stand 202.

At this time, a tape 203 cut to a predetermined dimension is set on the tape stand 202, and the edge of the stack of the recording sheet 12 is pressed against the surface of the tape 203 on the tape stand 202. have.

Then, as shown in FIG. 28 (b), the gate 202a of the tape stand 202 is opened in accordance with the information from the gate opening / closing sensor 203, and the tape 203 is provided at the edge of the stack of the recording sheet 12. Is moved to the side of the adhesive roller 206 in a state where it is attached, and the tape 203 is bound to one edge of the stack of the recording sheet 12 by passing through the adhesive roller 206.

Thereafter, as shown in FIG. 28 (c), the feed roller 205 and the belt holder 201 are reversely rotated to return the stack of the recording sheets 12 where tape binding is completed to the original target bin tray 40, and again. The target bin tray 40 is moved downward by 1/2 pitch to complete the binding operation.

When the belt gripper 201 is retracted in FIG. 28A, the presence or absence of the recording sheet 12 is checked by the sheet presence detector 214, and when it is determined that the recording sheet 12 exists, subsequent binding processing is performed. Is executed but it is determined that there is no recording sheet 12, the belt gripper 201 immediately stands up and the binding process for the bin tray 40 is stopped, and the process for the next bin tray 40 is shifted.

◎ Specific example of binding process (FIG. 29)

Now, when the sorting process is completed, as shown in FIG. 29 (a), the stapler 100 moves to the retracted position Q and the post-treatment set position (the binder 200 is opposed to the post-treatment stage F) W) is set. Moreover, each bin tray 40 is arrange | positioned in the binding initial position in which the bin tray 40 (n) located in the fractional-number of the small numbering water n is located in the post-processing stage F. As shown in FIG.

In this state, as shown in FIGS. 29 (a) to 29 (c), the bin trays 40 (n), 40 (n-1) ... 40 (1) to be bound move downward by one pitch, and the binder 200 The tape binding by) is sequentially performed, and a series of binding processes are completed at the stage where the tape binding to the final bin tray 40 (1) is completed. Then, as shown in FIG. 29 (d), after the binder 200 is lowered to the retracted position away from the post-treatment set position w, the stapler 100 returns to the initial position P0 and the bin tray 40 is removed. Is returned to the initial spotting position to prepare for the next sorting process.

In operation 171, the moving amount 405 is moved to stop the enemy by moving the moving cart according to the size of the recording sheet 12, and the stapler 100 and the puncher 300 are selectively set at the processing position. In addition, the guide rail 401 and the linear guide portion 402 extending in a range corresponding to the approximately width dimension of the bin tray 40 along the raised flange 42 of the bin tray 40, as in the first embodiment The recording sheet 12 corresponding to the cutout portions 403 of the bin tray 40 and the curved guide portion 403 which is bent against the corner portions corresponding to the cutout portions 43 of the bin tray 40. Stapling by the stapler 100 and punching by the puncher 300 are performed to the locations (represented by P0, P1, and P2, respectively).

In this embodiment, the stapler 100 and the puncher 300 are movable carts 405 through the retreat position shift systems 410 and 420 (corresponding to the retreat position shift system of Example 1), respectively, as shown in FIG. ), And as shown in Figs. 31 (b) and (c), the enemy can advance and retreat between the processing execution position A and the standby position B.

It consists of the swinging arm 307. As shown in FIG.

Next, an example of the post-processing flow of the sensor according to this embodiment is shown in Figs. 33 (a) and (b).

In the figure, the CPU 171 first determines that the sorting process is completed (ST 1), and then checks whether or not stapling processing is necessary (ST 2).

When it is determined that stapling processing is necessary, the bin tray 40 is set at the initial stapling position (ST 3). It is determined whether the stapling mode is the dual mode or the corner mode (ST 4).

When it is determined that the stapling mode is dual, the stapler 100 after calculating the movement amount of the stapler 100 to each of the stapling positions P1 (S) and P2 (S) according to the size of the recording sheet 12 (ST 5). ) Is moved to the first stapling processing position P1 (S) (ST 6).

Then, the stapling basic operation is performed (ST 7), it is checked whether or not the stapling target is the final bin tray 40 (ST 8), and if it is not the final bin tray 40, the bin tray 40 is pitched one pitch. Move up or down by minutes to set the bin tray 40 of the next stapling target to the post-processing stage F (ST 9), and then ST 7 to ST 9 until the punching target becomes the final bin tray 40. Repeat the process until.

Subsequently, it is checked whether or not all stapling processing has been completed at the stage where the final stapling operation for the stapling position P1 (S) is finished (ST 10), and if it is not completed, the stapler 100 is next stapled. After setting at the ring position P2 (S), the processes of ST 7 to ST 9 are repeated until the stapling processing for all the bin trays 40 is completed.

When it is determined that the stapling process is completed or when it is determined that the stapling process is not necessary in ST 2, it is checked whether or not the punching process is required (ST 11).

At this time, when it is determined that the punching process is necessary, the initial punching position (the initial position of the bin tray 40 at the start of the punching process; ), The bin tray 40 is set (ST 12), and the amount of puncher movement (two punching positions) (the amount of movement to P1 (P) and P2 (P)) is calculated according to the size of the recording sheet 12. (ST 13) First, the puncher 300 is moved and set to the punching position P2 (P) close to the stapling position P2 (S) (ST 14).

Then, the punching basic operation is performed (ST 15), it is checked whether the punching target is the final bin tray 40 (ST 16), and if not the final bin tray 40, the bin tray 40 is divided by one pitch. Move up or down to set the bin tray 40 of the next punching target to the post-processing stage F (ST 17), and then process from ST 15 to ST 17 until the punching target becomes the final bin tray 40. Repeat.

Subsequently, it is checked whether or not the punching process is completed at the stage where the final punching operation for the punching position P2 (P) is completed (ST 18). If not, the puncher 300 is moved to the next punching position P1 (P). ), The processes of ST 15 to ST 17 are repeated until the punching processing for all the bin trays 40 is completed.

If it is determined that the punching process is completed or if it is determined that the punching process is not necessary in ST 11, all post-processing is assumed to be completed, and the stapler 100 and the puncher 300 are initially positioned (in this embodiment, the corner post-processing position). (Corresponds to P0) to prepare for the next sorting process (ST 19).

Next, FIG. 34 shows a specific example of post-processing according to such a processing flow.

At the start of the post-processing, as shown in Fig. 34A, the stapler 100 and the puncher 300 are arranged at the initial position P0.

In this state, the stapler 100 is first moved to the first stapling position P1 (S), and then stapling processing is performed for each bin tray 40 (Fig. 34 (b)). 100 is moved to the second stapling position P2 (S), and then stapling processing is performed for each bin tray 40 (FIG. 34 (c)). The puncher 300 is set at the punching position P2 (P) and punched out for each bin tray 40 (Fig. 34 (d)), and the puncher 300 is moved to the first puncher position P1 (P). Then, punching is performed on each bin tray 40 (Fig. 34 (e)), and the stapler 100 and the puncher 300 are returned to the initial position P0.

In this process, the stapling process is performed first, so that the recording sheet 12 is not broken during the punching process, and the positional shift of the punching can be reliably avoided.

Moreover, as a modification of the post-treatment process of the sensor by this Example, the thing shown in FIG. 35 is mentioned, for example.

That is, at the start of the post-processing, the stapler 100 and the puncher 300 are arranged at the initial position P0 as shown in Fig. 35A.

The opponent first moves the puncher 300 to the first punching position P1 (P), and then punches the bin trays 40 (Fig. 35 (b)), and then the stapler 100 Is set to move to the first stapling position P1 (S), and then stapling processing is performed for each bin tray 40 (FIG. 35 (c)), and then the puncher 300 is second punched. Set at position P2 (P) to punch out the bin trays 40 (Fig. 35 (d)) and set the stapler 100 at the second punch position (P2 (P)). The punching process is performed on the bin tray 40 (FIG. 35 (e)), and the stapler 100 and the puncher 300 are returned to the initial position P0.

In this process, the post-treatment position of the puncher 300 or the stapler 100 is processed in order from the front, and the movement distance of the puncher 300 and the stapler 100 can be reduced, and the puncher 300 accordingly. Therefore, the movement time of the stapler 100 can be shortened.

Example 3

The basic configuration of the socket according to this embodiment is substantially the same as that of the first embodiment, but unlike the first embodiment, as shown in FIG. 36, the lower portion of the sheet conveying system 30 and the width direction of the sheet conveying system 30 are different. In the first post-processing set position W1 of the space in the housing 21 according to the present invention, the same stapler 100 as in the first embodiment is disposed, and a position facing the stapler 100 is located in the first post-processing stage. It is set as (F1).

In addition, a second post-processing set position W2 is secured to the lower portion of the first post-processing set position W1, and the binder 200 as in Example 1 is provided at the second post-processing set position W2. The location which was arrange | positioned and opposed to this binder 200 is set as the 2nd post-processing stage F2.

In this embodiment, the bin tray 40 positioned at the sheet distributing stage E and the post-processing stage F1 has a continuous positional relationship and is also located at the post-processing stages F1 and F2. Is a gap g ₁ between the bin tray positioned in the sheet distribution stage E and the bin tray 40 located above and the bin tray 40 positioned in the post-processing stage F1. and each gap between the bin tray 40 positioned at the top and bottom g ₂ and the after-treatment stage (F) an empty tray 40 and each gap between the bin tray 40 positioned at the top and bottom g which is located ₃ is set sufficiently larger than the gap g ₀ between different empty tray 40. In addition, the gap g ₁ is set to a range that does not interfere with the sorting process, the gap g ₂ is set to a range that does not interfere with the stapling process, the gap g ₃ is set to a range that does not interfere with the binding process, and the gap g ₀ is empty. It is set in the range which the tray 40 does not contact.

According to the sorter according to this embodiment, for example, when a series of sorting processes are completed, for example, the stapling process and the binding process mode are selected, the stapling process by the stapler 100 is performed in the post-processing stage F1. The bin tray 40 is performed, and the binding process by the binder 200 is performed on all the bin trays 40 in the post-processing stage F2.

In this embodiment, the stapling process and the binding process are performed in separate post-processing stages F1 and F2, respectively. For example, as shown in FIG. 37, each stapling position P0, P1, P2 is used. The corner stapler 100c and the dual staplers 100a and 100b may be fixed to each other.

As described above, according to the invention of Example 1 or 2, a plurality of systems which interrelate to one edge of the recording sheet in the bin tray where the sorting process is completed in the sheet distribution stage and the other post-treatment stage are completed. The post-processing unit can be selectively or simultaneously disposed and the post-processing of multiple systems can be performed on one edge of the recording sheet, respectively, so that the post-processing of multiple systems can be performed continuously according to one edge of the recording sheet. In addition, compared to the case where only one post-treatment has been possible in the past, the post-treatment range can be greatly expanded, and a post-treatment stage can be provided to perform post-processing of multiple systems, thereby reducing the post-processing space. Spacers between the bin trays, In the larger type, the device can be made more compact as much as the height dimension of the bin tray can be suppressed.

In particular, the invention of Example 1 is effective when a large aftertreatment unit is used, and the invention of Example 2 is effective when a small aftertreatment unit is used.

According to the invention described in Example 3, a plurality of post-processing units which are mutually correlated to a position opposed to one edge of a recording sheet in the bin tray where the sorting process is completed in a plurality of post-processing stages different from the sheet distribution stage are disposed. In this case, post-processing of multiple systems can be performed on one edge of the recording sheet, respectively, so that inter-related post-processing of multiple systems can be performed continuously according to one edge of the recording sheet. On the contrary, not only can the post-treatment range be greatly expanded, but also the apparatus configuration can be simplified as much as unnecessary unit retreat means for setting the post-treatment unit at the portion facing the post-treatment stage compared to the invention of Example 1 described above. Example 2 Freedom of Layout of Each Post-Processing Unit Compared to the Invention To be increased.

In addition, according to the inventions of Examples 1 to 3, the post-treatment is performed while the recording sheet in which the sorting process is completed is accommodated in the bin tray, so that the post-treatment tray is separately installed or the recording sheet is placed in the post-treatment tray. There is no need to provide a conveying means for conveying the dummy, so that the complexity of the device can be avoided, and the post-processing unit is eliminated because the stack of the recording sheet is not broken when using the stack of the recording sheet in the post-processing tray. The fall of the post-processing quality by this can also be effectively avoided.

In addition, according to the present invention, since the post-processing unit can be suitably moved according to one edge of the recording sheet in the bin tray, a plurality of sets of post-processing can be easily performed by one post-processing unit without separately installing the post-processing unit. Depending on the size of the recording sheet or the like, optimization of the post-processing target point can be easily realized.

In addition, according to the present invention, if it is confirmed whether or not a recording sheet exists in the target bin tray, and if it is confirmed that the recording sheet does not exist, the post-processing operation for the target bin tray is canceled and immediately post-processing for the next target bin tray. Since the transition to the operation process is carried out, the post-processing process without wasteful post-processing operations can be achieved.
