The protective case 510 has an opening / closing cover 511 at the upper end. The cover 511 is opened when replenishing the needles, and the open / closed state is detected by the switch SW1.

Within the protective case 510, the stapler 520, as shown in FIG. 6, has rollers 543 and 544.
It is fixed to a belt 545 stretched endlessly. The belt 545 is driven in the direction of arrow c or c ′ by the driving force transmitted from the stepping motor M1 to the roller 543 via the belt 542.

The stapler 520 has an arrow c on the belt 545.
Alternatively, it moves up and down with the movement in the c'direction and is set at a predetermined bin position. The push-out unit 509 also moves in the vertical direction in synchronization with the stapler 520 via a linking unit (not shown).

At the initial position of the stapling process, the stapler 520 has returned to the home position corresponding to the first-stage bin 402, and the fact that it is set at this home position is detected by the photosensor SE15. For staple processing, the stapler 520 is in the bin 40.
Stepping down one bin at a time corresponding to 2, bin 40
This is performed by binding the sheets on the upper two sheets one by one.

The amount of movement of the stapler 520 is detected and controlled by the number of pulses driving the stepping motor M1. When the sensor SE18 detects that the staple needle 526 is gone during a series of stapling processes, the stapling process is interrupted at that time, and the position of the stapler 520 is stored using the number of drive pulses up to that point.

After that, the stapler 520 is moved to the home position. The operator opens the cover 511 and replaces the cartridge 527 with a new one. The end of such needle supply work is detected by turning on the sensor SE18 and turning on the switch SW1.

Next, the stapler 520 is moved downward by the stored number of pulses, returns to the original position, and the stapling process is continued from there.

In 309, the print flag Fp is set to "1". In step S310, the second job is continuously set (the details will be described later).

In step S311, a warning mode process for outputting a warning sound or the like is performed. In step S312, another input process is performed, and then the process returns to the main routine.

FIG. 15 shows the second step S304 in FIG.
6 is a flowchart showing a subroutine of job mode input processing.

Referring to the figure, in step S320, the user inputs the number of copies under the display shown in FIG. 10, and in step S321, the number of originals is similarly input.

The upper limits of the number of copies and the number of originals input here are set based on the number of copies and the number of originals processed in the first job. The upper limit value is the "second job settable area" at the bottom of the display section B shown in FIG.
Is displayed as. The second job settable area changes depending on the sorter mode and the copy mode. Each time the mode is switched, the second job feasible area is recalculated and displayed on the display unit B. The user in sorter mode
It is possible to select (1) sort mode and group mode, and (2) select bin priority mode and number of pages priority mode.

As the copy mode, the user can select one-sided → single-sided copy mode, two-sided → one-sided copy mode, and one-sided →
It is possible to select either of the double-sided copy modes.

The group mode is a mode in which copy sheets are distributed into bins for each original, and when copying a set number of a sheets and a number of original sheets of b, as shown in FIG. Is used to stock a copy sheet in each bin.

The sort mode is a mode in which the same copy sheet is sorted into each bin, and when a copy of a set number of a sheets and a number of original sheets of b is performed, as shown in FIG. Is used to stock b copy sheets in each bin.

The bin priority mode is a mode in which the bin used in the first job is also used in the second job.
The number-of-sheets priority mode sets the bin used in the first job to the second
This mode is not used in jobs. That is, in the bin priority mode, as shown in FIG. 19, the sheet J2 of the second job is superposed on the sheet J1 of the first job on the sorter. On the other hand, in the sheet number priority mode, as shown in FIG. 20, the sheet J2 of the second job and the sheet J1 of the first job are separated on the sorter.

As shown in FIG. 16, the allowable number of sheets that can be stored in one bin is m, the number of bins is n,
If the number of copies in the first job is a and the number of originals is b,
The settable area of the second job in the one-sided → single-sided copy mode is calculated as shown in Table 1.

[0115]

[Table 1]

Similarly, the settable area of the second job in the double-sided → single-sided copy mode is calculated as shown in Table 2.

[0117]

[Table 2]

The settable area of the second job in the simplex → duplex copy mode is calculated as shown in Table 3.

[0119]

[Table 3]

Specifically, the permissible number of sorters is 50 [sheets /
Bin], and the sorter number is 20 [bin], the first job has a copy number of 5 [sheets] and an original number of 8 sheets.
The settable area of the second job after the copy of [sheet] is shown below.

Table 4 shows the case of the single-sided → single-sided copy mode.
Table 5 shows the case of the double-sided → single-sided copy mode, and Table 6 shows the case of the single-sided → double-sided copy mode.

[Table 6]

Returning to FIG. 15, in step S322, as shown in FIG.
When the mode key of the display unit A of 0 is turned on, the display of FIG. 11C is performed in step S323. When the mode selection of FIG. 11C is performed in step 324, the settable area of the second job is recalculated by the calculation method shown in Tables 1 to 3 in step S325. In step S326, the screen B of FIG. 10 is displayed, and the value after the settable area of the second job is calculated is displayed in the lower part of the display unit B.

At step S327, when the sorter mode key on the display section A of FIG.
At 328, the display of FIG.

When the sorter mode selection of FIG. 11G is performed in step S329, the settable area of the second job is calculated by the calculation method shown in Tables 1 to 3 in step S330, and the setting is performed in step S331. 10
The display returns to (B), and the value calculated as the possible area of the second job is displayed.

In step S332, other processing is performed, and the process returns to the panel input routine. FIG. 21 is a flowchart showing the processing in the warning mode subroutine of step S311 of FIG.

This routine is a routine for outputting a warning sound or a message and prompting the setting input of the second job if there is no input of the second job setting for a certain period of time after setting the original of the second job. Further, this is a routine for performing a resetting process when the paper is removed on the way.

When it is detected in step S340 that the second job set detection sensor SE1 in FIG. 7 is turned off, the job timer TMJ is started in step S341.

If OFF → ON is not detected in step S340, it is determined in step S342 whether the second job set detection sensor SE1 is ON or OFF. If YES in step S342, the job timer TMJ is reset in step S343, and the process returns to the panel input routine. The process in step 342 is
This is a process corresponding to when the paper of the second job is removed on the way. After the processing in step S341, step S3
At 44, the job timer has a certain time (for example, 100
If it is determined that the time has not elapsed (YES in S344)
S) directly returns to the panel input routine.

If it is determined in step S344 that the job timer has exceeded the fixed time, step S345.
Then, it is determined whether or not the second job is input. If YES in step S345, the process directly returns to the panel input routine. If NO in step S345, in step S346, the warning message shown in FIG. 22 is output to the display unit B, and at the same time, a warning sound is output. Then, the process is moved to the panel input routine.

FIG. 23 shows the second step S310 in FIG.
6 is a flowchart showing processing in a subroutine for continuous setting of jobs.

Referring to the drawing, it is determined in step S350 whether job continuous key 606 has been pressed. If YES in step S350, it is determined in step S351 whether the flag F ₁₀ of the job continuous key 606 is "1".

If YES in step S351, the flag F ₁₀ is set to "0" in step S352, and if NO in step S353, the flag F ₁₀ is set to "1".

In step S354, it is determined whether or not the flag F ₁₀ is "1". If YES, step S35
In step 5, the continuous mode display LED 613 lights up, and if NO, in step S356, the individual mode display LED 614.
Lights up.

In step S357, it is determined whether or not the flag F ₁₀ is "1". If YES, step S3
At 58, continuous mode processing is performed. Specifically, the set contents such as the number of copies and the number of originals set in the first job are copied to the contents of the second job. Thereafter, in step S359, the first job stapling flag F ₁₁ for setting whether or not to perform the stapling processing for the first job is set to "0" to prohibit the stapling processing (post-processing) for the first job.

By the processing in step S359, the stapling processing at the end of the first job is forcibly disabled. The stapling operation after the completion of the second job can be performed in the mode set for the first job.

On the other hand, if the flag F ₁₀ is "0" in step S357, the processes in steps S358 and S359 are not performed in order to individually process the first job and the second job, and the process directly returns to the main routine. .

If NO at step S350,
The processing from step S357 is performed.

With the processing shown in FIG. 23, when the continuous job mode is set by the job continuous key 606, the user can set the original group following the original group of the first job as the second job. . After the copy processing of the first job is completed, the post-processing (stapling operation) of the copied paper is not performed until the copy processing of the second job is completed. As a result, continuous processing can be performed in the first job and the second job, which improves the usability of the apparatus.

When the continuous mode is set, the user sets the continuous originals in the first job and the second job, which is specifically performed as shown in FIG.

Referring to FIG. 24, in the copying machine adopting the last page system shown in FIG. 24A, the user sets the rear half of the original continuous to the first job in order from the top. The first half of the originals continuous with the second job are set in order from the top. Specifically, the continuous manuscript is page 1
1 to 100, the originals of pages 1 to 50 are set in order from the top in the second job, and
The originals of pages 51 to 100 are set in the job in order from the top. As a result, after the copy sheets of 1 to 100 pages are placed in order from the top in each bin in the sorter in the sorter, post-processing such as stapling is performed.

On the other hand, in the copying machine adopting the first page system, as shown in FIG. 24B, the user sets the first half of the continuous original group to the first job in order from the top and the latter half. The parts are set in the second job in order from the top. Specifically, when the original group is composed of pages 1 to 100, the first job is set with originals 1 to 50 in order from the top, and the second job is set to be 51 in order from the top. A manuscript of pages 100 to 100 is set.

Also in this case, the sorter is also shown in FIG.
As shown in FIG. 3, after the originals of pages 1 to 100 are sequentially output to each bin, post-processing such as stapling is performed.

As described above, the manner of placing the original differs depending on whether the last page system or the first page system is adopted, but the control can be similarly performed regardless of which system is used.

[Operation of ADF] FIG. 25 shows ADF
5 is a flowchart for explaining the operation of FIG.

Referring to the drawing, in step S401, it is determined whether or not the print operation is being performed, based on whether or not print flag Fp is "1". If NO, the process here ends.

If YES in step S401,
In step S402, it is determined whether or not there is a manually placed document by determining whether or not the document detection sensor SE set inside the copying machine (not shown) is on. This is to prevent the ADF from operating if there is a document to be placed on hand. If YES, the process here ends.

If NO in step S402, it is determined in step S403 whether the ADF opening / closing sensor SE100 is "0". If YES in step S403, it is determined in step S404 whether or not there is a document in the first tray paper feeding unit depending on whether the paper feeding unit paper empty sensor SE3 is "1".

If YES in step S404, the second tray movement timer t ₁ is reset to "0" in step S405. Then, in step S406, the ADF sheet feeding operation is started, and the process returns to the main flow.

If NO in step S404, the ADF paper feed operation routine is entered in step S407, and the operation is stopped for a certain period of time.

In step S408, the sensor SE1 is "1".
It is determined whether or not documents are stacked on the second tray. If the originals are stacked on the second tray, SE1 becomes "1", and the process proceeds to the second job. The sensor SE1 is arranged on the second tray and moves simultaneously with the second tray. As a result, it is possible to detect when the user removes a document that is moving on the second tray. Further, a plurality of sensors may be provided so that the presence of the document can be detected regardless of the position of the second document.

If YES at step S408, the end of the first job is determined at step S409. The end time of the first job is any one of the following four time points (1) to (4). The post-processing operation of the first job is performed by selecting any one of (1), (2), and (4) from among the four types of end determination times listed in (1) to (4) as the end time. Since the movement of the second tray is started, the productivity is improved.

(1) When the original on the first tray of the ADF is empty (2) When the copy paper of the first job is ejected from the copying machine main body (3) Post-processing of copy paper such as stapling When completed completely (4) Timing when the copy paper of the second job is set to be ejected to the bin immediately after the completion of the post-processing of the first job Ease of processing at the time of paper jam (paper jam) Depending on the purpose of improving the system configuration or productivity, the most preferable one among the above points (1) to (4)
It can be set as the end time of the job.

If NO in step S409, the process is ended here. If YES in step S410, the presence or absence of the document at the ADF paper feed port is determined by the sensor SE3 being "1". After the completion of the first job, if there is an interrupt document before the second job set, the sensor SE3 becomes "1", and the process returns to the main flow to prioritize the interrupt document. If there is no document, the second tray is moved toward the paper feed port in step S411.

Next, if the originals of the first job and the second job are both discharged to the same discharge tray, both document groups will be mixed, so the discharge block is shifted by the shift block. The operation of sorting the document group is started.

Specifically, when the start of the movement of the second tray is detected in step S420, step S42.
In 1, the operation of shifting the paper discharge tray by the shift block, moving the document discharged in the first job, and shifting it from the document discharge position in the second job to be performed is performed.

Next, in step S412, the second tray movement timer t ₁ reset when the original of the first job is emptied on the first tray in step S405.
Is "0".

If YES, the jam processing detection time A is substituted into the timer t ₁ in step S413, and if NO, the substitution is not performed.

At step S414, 1 is subtracted from the timer t ₁ into which A is substituted every time the 1-cycle routine is turned, and the subtracted value is substituted into the value t ₁ of the timer.

The jam processing detection time A has an arbitrary time margin to the time required from the start of movement of the second tray on which the original is set to the setting of the original on the ADF sheet feeding section. The added value is set by the set value corresponding to the document size detected by the document size detection unit. If the second tray continues to move for a time exceeding the value A, it is determined to be in trouble in step S417 described below.

In step S415, the size of the original is detected. In step S417, the process for the case where the original of the second job is not properly moved is performed. The detailed contents will be described with reference to FIG.

In step S419, the process of shifting the setting of the second job to the first job is performed. This process will also be described later.

If NO in step S408, determine the second
This is the case where there is no document on the tray, and the processing corresponding to the paper empty is performed in step S418.
This process will also be described later.

If NO in step S403, the ADF opening / closing support routine is executed in step S416.

FIG. 26 is a flowchart showing the specific processing of the ADF opening / closing support routine (S416) of FIG.

This process is a process for prohibiting the movement of the tray of the second job when the ADF is opened during job processing. Specifically, step S416
In 01, the print flag Fp is set to “0”, the movement of the second tray is stopped in step S41602, and then the process returns to the main flow.

FIG. 27 is a flow chart showing the specific processing in the second document movement defect coping routine (S417) of FIG.

This process is a process for responding to an abnormality occurring while the document of the second job is moving.

Referring to the figure, the steps S412, S4
The second tray movement time timer t ₁ which has been counted down in steps 413 and S414 is set in step S4170.
In 1, it is determined whether or not it is "0".

If YES in step S41701, the print flag Fp is set to "0" in step S41702. Next, in step S41703, the movement of the second tray is stopped.

If NO in step S41701, the process returns to the main routine. When these troubles are detected, step S7 shown in FIG.
At, a warning message is output on the panel.

FIG. 28 is a flow chart showing the specific contents of the routine for shifting the second job setting to the first job (S419) in FIG.

This process is a process for setting the contents of the second job as the first job. In step S41901, it is determined whether the second job key is ON.

If YES in step S41901,
When the second job is processed, step S41902
In step 2, the settings of the second job are copied to the settings of the first job.

On the other hand, if NO in step S41901, the process proceeds to step S7 in FIG. 13, and a warning process for urging the setting of the second job is performed in the warning routine.

FIG. 29 is a flow chart showing the specific processing in the paper empty handling routine (S418) of FIG.

This process is a process for the second job when the paper is empty. Referring to the drawing, when it is detected that the sensor SE3 of the first tray is "0" and there is no original (NO in S404), the sensor S of the second tray is
When E1 is "0" (NO in S408), the setting of the second job is canceled (cleared) in step S41801.

This makes it possible to set the second job and set the originals again until the originals on the first tray become empty. When the user removes the original set in the second job while moving the second tray, it is determined in step S41802 whether the second tray home position detection sensor SE9 is "1", and the determination result is NO. For example, in step S41803, the second
Move the tray to the home position.

If the player returns to the home position (S
(YES in 41802), the second tray is stopped in step S41804, and the print flag Fp is set to "0" in step S41805.

After the second tray is moved to the paper feeding section in the second job, it stays there until the end of the second job.
Return to the home position after finishing the job.

When the continuous multi-job is executed (when the third or more jobs are executed), after the pre-paper feeding paper empty sensor SE3 becomes "1",
It is necessary to control so that the second tray returns to the home position after a fixed time.

[Post-Processing Operation] FIG. 30 is a flowchart showing the process performed in the post-processing operation (S6) of FIG.

Referring to FIG. 30, it is determined in step S601 whether the print flag Fp is "1". If YES, the sorter is controlled in step S602.

In step S603, it is determined whether or not the first job is completed, and if YES, step S6
In 04, the stapling process is performed. At this time,
If the first job staple flag F ₁₁ is “0”, the first
No stapling process is performed in the job.

The determination of the end of the first job is made similarly to the determination in step S409 of FIG.

If NO in step S601 or NO in step S603, the process here ends.

FIG. 31 is a flow chart showing the processing in the stapler control routine (S604) of FIG.

In the copying machine of this embodiment, when the copy sheets of the first job and the second job are discharged to the same bin, the copy width of the original of the first job is smaller than that of the original of the second job. The feature is that alignment and stapling are performed only when the size is small.

Referring to the drawing, it is determined in step S605 whether or not the job is the first job. If YES, the matching section performs matching in step S606.
In step S607, it is determined whether or not the first job is completed. If YES, the stapling process is performed only in step S608 when the staple flag F ₁₁ in the first job is other than "0". Ends the process.
If NO in step S607, the process here ends.

If NO in step S605,
In step S609, it is determined whether the width a of the copy sheet of the first job is smaller than the width b of the copy sheet of the second job. If YES, a matching process is performed in step S610, and it is determined in step S610a whether or not the second job is completed.

If YES in step S610a, staple processing is performed in step S611, and the processing here is terminated.

If NO in step S610a, the process is ended here. NO in step S609
If so, in step S610b, it is determined whether or not the staple mode is selected. If it is selected, the staple mode is canceled in step S610c, and then the processing here is ended.

The reason why the aligning and stapling process is performed only when the copy width of the copy paper in the second job is larger than the width of the copy paper in the first job is as follows.

Referring to FIG. 32, when the copy sheet J2 of the second job is larger than the copy sheet J1 of the first job, when the push-out unit 509 pushes the copy sheet J2, Only the paper J2 of two jobs can be stapled.

After the stapling process shown in FIG. 32, the aligning section 508 can align the sheets of the first job and the second job as shown in FIG.

In FIG. 33, the original of the second job is stapled at position ST.

In the present embodiment, the aligning process and the stapling process are performed when the sheet of the second job is larger than the sheet of the first job. However, the sheet size of the second job is the sheet size of the first job. In the above case, the matching process may be performed. In this case the first
This is because when the paper size of the job and the paper size of the second job are the same, they cannot be individually stapled in the same tray, but only the alignment process can be performed in the same tray.

The advantages of the copying machine in this embodiment are as follows (1) to (3).

(1) When the width of the copy sheet in the second job is equal to or larger than the width of the copy sheet in the first job, even if the copy sheets in the first job are stacked on the output tray, It is possible to perform post-processing such as alignment and stapling of copy sheets for the second job.

(2) When it is desired to perform copy processing exceeding the number of sheets that can be stacked on the ADF tray,
By dividing the originals into the first job and the second job and stacking them, it is possible to perform continuous processing of the first job and the second job.

(3) Since the inputtable area of the second job is displayed on the panel based on the setting of the first job,
It is possible to prevent troubles due to incomplete input in the second job.

The enterable area may be indicated by voice or the like. Further, in order to limit the setting of the copy operation mode for the second job according to the copy operation mode executed in the first job, for example, the sort operation is performed using all the bins of the sorter in the first job. In this case, the sorting operation may not be set in the second job.
