FIG. 10 shows the main components such as a detection means for providing information to the microcomputer 107 and a display device controlled by the microcomputer 107, so these will be explained briefly.

Information such as the copy ejection sensor 37 and the bin copy paper sensor 38 is provided to the microcomputer 107 via the input interface circuit 106. A job partition display 39 and the like are connected to the output interface circuit 108 of the microcomputer 107.

Next, various operation keys and displays in the multi-job mode will be explained based on FIGS. 7 to 10.

The multi-job key 52 is used to set the multi-job mode. If the multi-job key 52 is pressed once when the one-job mode is set, the multi-job mode is set, and if the multi-job key 52 is pressed one more time, the one-job mode is set.

The number of originals key 56 is used to input the number of originals per job in multi-job mode. Original number key 56
When is pressed, the original sheet number set counter display 64 goes silent, and then the value entered using the numeric keypad 48 is counted by the original sheet number set counter provided in the microcomputer 104.
The number of original sheets is also displayed on the set counter display 64. In this case, to change the value entered using the numeric keypad 48, press the clear/stop key 51 and then input the desired value again using the numeric keypad 48 (XJ).

The number of copies key 57 is used to input the number of copies per job in the multi-job mode.

When the number-of-copies key 57 is pressed, the number-of-copies set counter display 49 blinks, and then the value input using the numeric keypad 48 is counted by the number-of-copies set counter provided in the microcomputer 104. It is displayed on the sheet number set counter display 49. In this case, in order to change the value entered using the numeric keypad 48, it is sufficient to press the clear/stop key 51 and then input the desired value again using the numeric keypad 48.

The input key 58 is used to input the contents of the original number set counter and the number of copies set counter to the microcomputers 1040B and 1040AM during multi-job keying.

The number confirmation key 66 is used to display the input job in multi-job mode to confirm the content of the job.

For example, if the contents of the first job (the number of sheets set for originals and the number of sheets for copy set) are displayed, "1" is displayed on the number display 54, and if you press the number confirmation key 66 at this time, The number display value is incremented to "2" and the contents of the second job are read out from the RAM and displayed. If you wish to display the contents of a desired number of jobs, hold down the number confirmation key 66 and input the desired value using the numeric keypad 48, and the value entered using the numeric keypad 48 will be displayed on the number display 54. Moreover, when the user releases his or her finger from the number confirmation key 66, the contents of that number of jobs are displayed.

The remaining amount check key 67 is used to display the number of originals and the number of copies that can be input in the multi-job mode. Only while the remaining amount check key 67 is pressed, the number of inputtable originals is displayed on the original number set counter display 64,
In addition, the number of copies that can be input is displayed on the copy number set counter display 49.

The job cancel key 68 has four functions.

The first function of the job cancel key 68 is to clear the contents of the input job.

Enter the contents of the number of jobs you want to clear and press the number confirmation key 66.
When the job cancel key 68 is pressed, the contents of that number of jobs are cleared, and the contents of the next number of jobs are sequentially transferred.

The second function of the job cancel key 68 is to interrupt the copying operation in the middle of execution of the job after starting the copying operation, and to stop the execution of the job. When the job cancel key 68 is pressed when the copying operation is interrupted, "1" is added to the value of the job execution counter, and when the next print key 47 is pressed, the next number of jobs are executed.

The third function of the job cancel key 68 is to clear the original number execution counter and the copy number execution counter for all jobs after all jobs are executed. When the job cancel key 68 is pressed after all jobs are executed, the original number execution counter and the copy number execution counter for all jobs are cleared.

In this case, the contents of the original sheet number set counter and one copy sheet number set counter for all jobs are not cleared.

The fourth function of the job cancel key 68 is to turn it off when the number of original sheets mismatch display 69 is turned on before copying is executed, and to turn it off when the number of original sheets mismatched display 69 is turned on after copying is executed. At the same time, "1" is added to the value of the job execution counter.

Since the main routine of the flow for explaining the operation of 20' is shown, this will be explained next.

When the power key 45 is turned on, initial settings are performed in step (3). In step (2), the input interface circuit 103 and output interface circuit 105 of the microcomputer 104 are cleared.

Next, go to the standby routine of step (■). This standby routine consists of subroutines 1 to 15.25.

F38) Next, the process goes to step (2), a document feed control routine.

This document feed 9 control routine consists of subroutines 19 to 21.Next, in step 2, it is checked whether or not the print key 47 is OK to accept, and if it is OK, in step 2, the copy start flag FGI 41 is set to 1. Check whether or not. If the print key 47 is not accepted in step ■ and the copy start flag FGI 4 is set in step ■
If 1 is not equal to 1, return to step (■).

If the copy start flag FGI 41 is 1 in step (2), the process goes to the copying operation start routine in step (2). This copying operation start routine consists of subroutines 16.18. Next, the process goes through the original feed 9 control routine in step (2) and then goes to the copying operation control routine in step (2). This copying operation control routine consists of subroutines 17.25. Next, after going through the document feed control routine in step ■, it is checked in step [phase] whether or not the interruption was caused by turning on the stop key. If the interruption was not interrupted, in step ◎, the number of copies set for one document = the number of copies to be executed. Check whether or not.

If in step 0, the number of copies set for one original does not equal the number of copies to be executed, the process returns to step (2).

If the interruption is caused by turning on the stop key in step [phase], and if in step 0 the number of copies of one document set = the number of copies to be executed, the process goes to the final processing routine of step 0. This final processing routine is subroutine 17.
．． Consists of 25.

Next, through the document feed control routine in step [phase], it is checked in step 0 whether or not the final processing has been completed. If the final processing has not been completed, the process returns to step @. If the final processing is completed in step 0, it is checked in step [phase] whether or not the operation is completed, and if the operation is not completed, the process returns to step (2).

FIG. 12 shows the main routine of the flow for explaining the operation of the sorter 3, which will be explained next.

When the power key 45 is turned on, initial settings are performed in step [phase]. In this initial setting, microcontroller 10
7's input interface circuit 106 and output interface circuit wr108 are cleared.

Next, the program goes to step 0, a standby routine. This standby routine consists of a subroutine 23. Next, in step [phase], it is checked whether there is a start signal or not, and if there is no start signal, the process returns to step 0.

When there is a start signal at step [phase], step [phase]
The mode is set to either standalone mode or stack mode. Next, go to the classification operation control routine of step [phase]. This classification operation control routine consists of a subroutine 22.

Next, in step O, it is checked whether the number of set copies of one original document=the number of sheets stored in the bin. If the number of copies set for one original does not equal the number of sheets stored in the bin in step O, step [
Go back to [phase]. Number of copies set for one original in step O =
If it is the number of sheets stored in the bin, the process goes to the final processing control routine of step [phase]. This final processing control routine consists of a subroutine 24.

Next, in step (c), it is checked whether the operation has ended or not, and if the operation has not ended, the process returns to step 0.

The subroutines of the main routine of the flow for explaining the operation of the electronic copying machine of the present invention shown in FIGS. 11 and 12 are shown in FIGS. 13 to 36, and these subroutines will be explained next. do.

FIG. 13 shows subroutine 1.

This subroutine 1 is included in the standby routine of step (2) and sets or resets the multi-job mode.

First, in step [phase], it is determined whether or not the multi-job key 52 is ON. If the multi-job key 52 is ON, FGTRABL=1 is checked in step O. If FGTRABL=1, FG1 in step [phase]
Check whether 1=1. If the multi-job key 52 is not ON, the process returns to the main routine after setting FGII to 0 (step [phase]). Step■
If F'QTR,ABL=1 and step [
If PG11=1 in phase], return to the main routine. Therefore, FGTRABL=1 and (AQ
If a problem occurs, changing between the 1-job mode and the multi-job mode is prohibited.

If FG11 is not 1 in step [phase], FGII is set to 1.
After that, it is checked whether FGI2=1 or not, and if FG12=1, it is the multi-job mode, so FGI2'el is set and the process goes to step O~[phase]). In step [phase], set the number display 54 to O.
N, the number counter display 55 is set to 1, the number of original sheets display 63 is set to ON, and the number of original sheets set counter display 6 is set.

and set the number of copies set counter display 49 to 0,
The copy number execution counter display 50i is turned OFF, and the original number key press indicators 59a and 59b are turned ON. Next, in step (2), a multi-job mode signal is output to the sorter 3 and the process returns to the main routine.

If FG12=1 in step [phase], this means that the multi-job mode is canceled and one-job mode is set, so in step [phase], F'GI 2 is set to O, and then the process goes to step [phase]. In this step [phase], the number display 54, the number counter display 55, the number of original sheets display 63
, turns off the original sheet number set counter display 64 and the original sheet number execution counter display 65, puts 1 in the one copy number set counter display 49, and turns off the one copy number execution counter display 50. Original sheet number key press indicator 59a.

After putting 0 into JBPT, CTJBTC and CTJBPC (steps [phase] to O), the process returns to the main routine.

Next, subroutine 2 and subroutine 3 shown in FIG. 14 will be explained. These subroutines 2 and 3 are included in the standby routine of step
The number of original sheets key 56 and the number of copies key 57 are accepted.

First, in step [phase] it is checked whether or not the number of originals key 56 is ON, and if it is ON, then in step [phase]
Check whether e21=1.

If the original number key 56 is not ON in step [phase], Fe21 is set to 0 in step @ and the process returns to the main routine. Further, if Fe21 =1 in step [phase], the process returns to the main routine.

If FG21 is not 1 in step [phase], PO21 is set to 1 in step O and FGI2-1 is checked in step @. If F G 12 = 1, it is not the multi-job mode and the process returns to the main routine. If FGI 2 = 1, it is the multi-job mode, so in step @, it is checked whether the original number confirmation display 71 and the copy number confirmation display 72 are ON or not, and they are ON. and Step @ (CTJ BP
T)≦[Check CTJBTCI. (CT
JBPT) is the number of jobs currently displayed, and [CTJBTC) is the maximum number of jobs that have been input.

If the original number confirmation display 71 and copy number confirmation display 72 are ON, it is not possible to input more than the currently input data, so only changes to the data of the already input job are accepted. [CTJBPT]≦(C
'l'JB'l'C), the process returns to the main routine.

If the original number confirmation display 71 and copy number confirmation display 72 are not ON in step @, and if (CTJBPT)≦(CTJBTC) in step @, the number of original pages discrepancy display 69 is displayed in step @. It is checked whether or not it is ON, and if it is, it returns to the main routine.

If the number of originals mismatch display 69 is not ON, check (CTJBPT) ([CTJBPC] in step @. (CTJBPC) is the number of executed jobs. Enter data about the executed jobs. Since it is not necessary, if it is [CTJBPT] ((CTJBPC), return to the main routine. (CTJBP
T) ((CTJBPC) otherwise (CTJBPT) = (
CTJBPC). (CTJBPT)=
If it is not [CTJBPC], the job is not yet executed, so input of the number of originals to be set is accepted. (CTJBP
If T) = (CTJBPC), it is checked in step @ whether the original number execution counter and the copy number counter are 0, and if they are not 0, the copy operation has already started, so the main routine Return to.

If the original number execution counter and the number of copies per copy execution counter are 0, it means that the copying operation has not yet started, so the number of originals set is accepted.

Next, in step @, it is checked whether or not the original number key 56 is ON, and if it is ON, Fe22=1 is checked (step [phase]). If Fe22=1, the original number key 56 has already been pressed, so the process returns to the main routine. Fe12; If not 1, set Fe22 to 1
After setting F'032 to 0, turn on the numeric key press indicator 62, and turn on the document number key press indicator 59a.
.

59b, turn off the copy number key press indicators 60a, 60b and the input key press indicators 61a, 61b (
Step 0~).

Next, subroutine 3 will be explained.

First, in step ■, it is checked whether the one copy number key 57 is ON or not. If it is ON, in step [phase]
Check 31=1. One copy number key 57 is ON
If not, Fe21 is set to O in step [phase] and then the process returns to the main routine.

If Fe31=1 at step O, the process returns to the main routine.

If Fe31 is not 1 at step [phase], F at step O
After setting e31 to 1, go to step @. Next, steps [phase] to @) common to subroutine 2 are passed.

Since the original number key 56 is not ON in step @, the process goes to step [phase]. In step [phase], Fe32=1 is checked, and when Fe32=1, the flow returns to the main routine. When Fe22=1, 1' and Fe32 are set to 1 and Fe12 is set to 0 (step [phase], Φ), and then the process goes to step [phase].

Next, subroutine 4 shown in FIG. 15 will be explained.

This subroutine 4 is included in the standby routine of step (2) and accepts input of the numeric keypad 48.

First, in step O, it is checked whether the numeric keypad 48 is ON or not. If it is ON, in step O, Fe41=1 is checked. If the numeric keypad 48 is not ON, the program returns to the main routine after setting FG 41 to 0 in step O. If Fe41=1, the process returns to the main routine.

If F'G41~1 is not found in step O, set Fe41 to 1 and check that Fe12=1 (step [phase],
・). If FGI2 is not 1, it is not the multi-job mode and the process returns to the main routine. FGI 2=
If it is 1, check Fe22=1, and Fe22=1
If so, the data on the numeric keypad 48 is entered into the document number set counter and displayed (in step 0). Next, in step [phase], check that [one copy number set counter] = 0, and if [one copy number set counter] = 0, turn on the one copy number key press indicators 60a, 60b, and press the numeric keypad. After turning off the press indicator 62 (step O), the process returns to the main routine.

[One Copy Counter] If it is not 0, the input key press indicators 61a and 61b are turned ON, the numeric key press indicator 62 is turned OFF' (step [phase]), and the process returns to the main routine.

If Fe22 = 1 in the above step [phase], step O
Check that Fe32=1. If Fe22=1, the data from the numeric keypad 48 is entered into the copy set counter and displayed, and the [original set counter] is checked to be 0 (step 0, O). [Original sheet number set counter) = O, the original sheet number key press indicator 59a,
59b is turned on, and the numeric key press indicator 62 is turned on.
After setting it as FF (step 0), return to the main routine. At step O, [original sheet number set counter] = 0
Otherwise, the input key press indicator 61a.

61b is turned on, and the numeric key press indicator 62 is turned on.
After setting it as FF (step [phase]), return to the main routine.

If Fe22 is not 1 in step 0, it is checked in step [phase] whether or not the set number confirmation key 66 is ON, and if it is not ON, the process returns to the main routine. When the number confirmation key 66 is ON, the data on the numeric keypad 48 is
TJBPT, set pe42 to 1 (step 0, 0), and then return to the main routine.

Next, subroutine 5 shown in FIG. 16 will be explained.

This subroutine 5 is included in the standby routine of step (2) and receives the input key 58.

First, in step [phase], it is checked whether the input key 58 is ON or not, and if it is not ON, the process returns to the main routine. If the input key 58 is ON, Fe22 = 1 is checked, and if F'G22 = 1, [one copy number set counter] = O is checked (step [phase]
, O). If Fe22=1, Fe22= in step O
1 is checked, and if FG32=1, the process goes to step O, and if Fe22=1, the process returns to the main routine.

If the [copy sheet number set counter] is not 0 in step O, it is checked that the [original sheet number set counter] = O in step 0. If [copy sheet number set counter] = 0 or [original sheet number set counter] = 20, the process returns to the main routine.

If [copy sheet number set counter] is not 0 and [original sheet number set counter] - 0, then (CTJB
The value of the copy number set counter and the value of the original number set counter are stored in the memory specified by PT) and displayed (step .).

Next, Fe22 and Fe22 are set to 0, input key press indicators 61a, 61b, numeric key press indicator 62, and number-of-copies key press indicator 60a.

60b is turned OFF (step [phase], [phase]). Next, after setting F'G51 to 1, (CTJ BPT)=M is checked (step O9 [phase]). This M is the maximum number of items that can be input in multi-job mode. If (CTJ BPT) = M, (CTJBTC) (
Check M (step).

In step [phase], if (CTJBTC) is not (M), that is, if the maximum input value is greater than M, it is impossible to input job data, so the process goes through subroutine 10 of step O and goes to main. Return to the routine. At step [phase], enter [CTJBTC] (if M, job data can be input, so set (CTJBTC) + 1 at step [phase], then go through subroutine 10 of step [phase] Return to main routine.

If (CTJBPT) = M in the above step [phase],
Next, there is an area for the number of jobs that can still be input, so after turning on the document number key press indicators 59a and 59b, check (CTJBPT))(CTJBTC) (step 0. [phase]). This is a check to see if the displayed job has been input. [CTJBP
T]) (CTJBTC), the displayed job has not been entered yet, so CTJ BP'I
' is put in CTJBT'C and goes through subroutine 7 to check whether or not the original number confirmation display 71 or the copy number confirmation display 72 is ON (steps [phase] to [phase]).

If the original number confirmation display 71 or copy number confirmation display 72 is not ON in step [phase] above, job input is possible (CTJBP'I")+
1, enter 0 in the document set counter, and display it.
After entering and displaying 0 in the copy number set counter, the process returns to the main routine through subroutine 1o (steps [phase] to [phase]). If the confirmation display 71 for confirming the number of original sheets or the confirmation display 72 for the number of copies placed in the above step [phase] is ON, it is impossible to input the job, so the main routine goes through the subroutine 1o of step O. Return to.

In the above step @ (CTJBPT)) (CTJBTC:
), the displayed job has already been input, so go through subroutine 7 and check whether the number of original sheets number confirmation display 71 or the number of copies number confirmation display 72 is ON or not. (Step φ■, O). If the original number confirmation display 71 or copy number confirmation display 72 is ON in step ■, it is impossible to input the job, and the process returns to the main routine through subroutine 10 of step [phase]. do.

If the original number confirmation display 71 or the copy number confirmation display 72 is not ON in the above step φ■, specify in step (multiple (CTJBPT) 11 and then step ○multiple (CTJBPT)). After displaying the contents of the memory in the copy number set counter and the original number set counter, the process returns to the main routine through the subroutine 10 of step [phase].

As described above, when the input key 58 is turned on, not only the data of the displayed job is stored in the memory, but also preparations are made so that the data of the next job can be input.

Next, subroutine 6 shown in the 17th cause will be explained.

This subroutine 6 is included in the standby routine of step (2) and accepts the number confirmation key 66.

First, in step ■, it is checked that Fe21 = 1, that is, it is checked whether there is an input job,
If FG51 is not 1, there is no input job, so there is no point in turning on the number confirmation key 66, and the process returns to the main routine.

If Fe21=1, it is checked whether or not the number confirmation key 66 is ON, and if it is ON, FG61=1 is checked (step Φ).

At step 0, (R1) (if not O, put the value of (R2) - 1 into R2 and check that (R2) = 0 (step 0, (■), at step ■ (R2) = If not O, return to step Φ■. At step ■■, (R1) (0
If so, since there is no set remaining amount value for the number of copies, the number confirmation display 72 for the number of copies set is turned ON (step 2).

If (R2) = 0 in step (■) above, or after step (■), enter the value of FLl into CTCPZZ (step (■)). The remaining amount value will be entered.

Next, the calculation of the remaining amount value of the set number of original sheets will be explained.

In step 2, put the value of CTJ BTC into R2, and in step 2, put Q into R3. This Q is the maximum number of originals 0 that can be set on the original setting table 2a of the ADF 2.

Next, in step (Q, enter the calculated value of (R3) - [number of originals set in the memory specified by (R2)] + (number of originals executed in the memory specified by (R2))] into R3.Next Step No), check (Ra) (O,

(Φ). If (R2) = 0 in step ■, step ○
Return to ]. If it is (R3) (O in step ), there is no remaining amount of original sheets set, so in step ■, the document number confirmation display 71 is turned ON.In step ■, (R2)
If =0 or after step (), the value of R3 is put into C'I'0RZZ (step ○α) and the process returns to the main routine. This CTORZZ will contain the remaining amount value of the set number of original sheets.

Next, subroutine 8 shown in FIG. 19 will be explained.

This subroutine 8 is included in the standby routine of step (2) and accepts the remaining amount confirmation key 67.

First, in step ), it is checked whether the remaining amount confirmation key 67 is ON or not, and if it is ON, FG12=1 is checked (Step 2). If FGI2 is not 1, there is no point in checking the remaining amount, so the process returns to the main routine. If FGI2=1, the contents of CTORZZ are displayed on the original sheet number set counter display 64, and the contents of C'l'C''PZZ are displayed on the copy number set counter display 49 (step 6α). ) Return to the main routine.

If the remaining amount confirmation key 67 is not turned on in step [F]),
The original sheet number set counter display 64 displays the original sheet number set value, and the one copy sheet number set counter display 49
Displays the set value for the number of copies and returns to the main routine.

Next, subroutine 9 shown in FIG. 20 will be explained.

This subroutine 9 is included in the standby routine of step (2) and accepts the job cancel key 68.

First, in step 6], the job cancel key 68 is turned ON.
0 job cancel key 6 to check whether or not
If 8 is ON, FG91=1 is checked (step ○α). If the job cancel key 68 is not ON, Fe21 is set to 0 (around step [phase]) and the process returns to the main routine. Fe21 = in step ○a
If it is 1, it returns to the main routine.

If FG91 is not 1 in step ○α, Fe21 is set to 1, and then it is checked whether the number of originals discrepancy display 69 is ON (step past).

(). ] If the number of original sheets mismatch display 6 is ON, after turning the number of original sheets mismatch display 69 OFF', it is checked whether the values of the number of original sheets execution counter and the number of copies execution counter are 0, i.e. , Check whether the displayed job is before execution (step), (f3■). If the original number execution counter and copy number execution counter are O in step ■, the displayed job is yet to be executed, so proceed to step [F]]
subroutine 7 of step a and subroutine 1 of step a
0 and return to the main routine.

If the values of the original sheet count execution counter and copy sheet count execution counter are not O in step (■), the displayed job has already been executed, so cancel the execution of this job and press [CTJBPC] in step (■). After setting the value to +1, a 1-job end signal indicating that the execution of the job has been completed is output to the sorter 3.

Next, in step ■ (CTJBPC) ((CTJBTC)
Check. [CTJBPC] ((CTJBTC
), it means that the number of executed jobs is greater than the maximum number of jobs entered, that is, there are no remaining jobs, so subroutine 7 of step ヰ and subroutine 10 of step and return to the main routine.

In step C), if (CTJBPC) ((CTJBTC), the number of executed jobs is smaller than the maximum number of jobs entered, so the value of CTJBPC is changed to CTJBPT.
(Step Φ)), and display the original number set value and copy number set value f in the memory specified by [CTJBPT), the original number set counter and the copy number set counter (step Φ)), Step ■

If the number of originals discrepancy display 69 is not ON in step ) above, then in step
Check T). In step 6) [CTJBTC
]≧[cTJBPT], the displayed job has not been input, and the process returns to the main routine.

If [cTJBTc]≧[cTJBPT] in step (), the displayed job has been input, so
It is checked whether the values of the original sheet count execution counter and the copy sheet count execution counter are O, that is, it is checked whether the displayed job is yet to be executed (step (α)).

If the values of the original number execution counter and one copy number execution counter are 0 in step (α), the displayed job has not yet been executed. The number of sheets set value is erased, and the contents of the next memory are sequentially filled without leaving the memory blank (step ■).

Next, in step (2), it is checked that (CTJBTC)=0. If (CTJBTC) = 0 in step ■, it is set to (CTJBTC) - 1 in step ○α, and if (CTJBTC) = 0 in step ■, after setting FG51 to O, it is specified by [C'rJBPT). The contents of the memory are entered into a copy number set counter and an original number set counter and displayed (step ○J). Next, numeric key press indicator 62, input key press indicator 61a, 61b
and one copy number key press indicator 60a, 60b'1O
As FF, in step (α), it is checked that [original sheet number set counter] = 0 (step Φα). Step O
If [original sheet number set counter] = 0, the original sheet number key press indicators 59a and 59b are turned on in step ■, and [original sheet number set counter] =
If it is not 0, the original number key press indicator 59a is displayed in step ■.
, 59b are turned OFF, the process returns to the main routine through subroutine 7 of step Φ■ and subroutine 10 of step ).

In step ○a above, [CTJBTC]≧[CTJBPT
], and if the values of the original sheet number set counter and the copy sheet number set counter are not O in step 6),
In step (■), check (CTJBTC)≧[CTJBPC].

If (CTJBTC) is not ≧ (CTJBPC), it means that all the input jobs have been executed, so in step Φ), erase all original sheet count execution values and copy sheet count execution values in the memory related to the job. , step■
After outputting an all-job end signal to the sorter 3 indicating that execution of all input jobs has been completed, the process returns to the main routine through subroutine 7 of step (2) and subroutine 10 of step (2).

The reason why the original number set value and the one copy number set value related to the job are not deleted from the memory in step (2) above is to eliminate the need for re-input when executing a multi-job with the same pattern.

In step O above, (CTJBTC)≧[CTJBPC]
If so, in step ), check [one copy number set counter] = [one copy number execution counter], and if [one copy number set counter] = [one copy number execution counter], step σD Check [Original sheet number set counter] = [Original sheet number execution counter].

Step Φ) If [original sheet number set counter] = [original sheet number execution counter], the job with the maximum number of input jobs has been executed and cannot be canceled, so the main routine Return to.

If [copy number set counter] = [copy number execution counter] in step ■ above, and if [original sheet number set counter] = [original sheet number execution counter] in step O, then the number of copies being executed in step To cancel the job, set (CTJBPC) +1, and after outputting the 1st job processing command signal to the sorter 3 in step ■,
Step ■Boil (CTJBTCI((CTJBPC)). At step ■■, check (CTJBTC)((
If it is not CTJBPC), some of the input jobs are not being executed, so go to step
Insert the BPC value into CTJBPT, and step ■)
The original number set value and one copy number set value in the memory specified by (CTJBPT) are entered into the original number set counter and the one copy number set counter and displayed.

In the above step ■■ (CTJBTC) ((CTJBPC
), the input job is being executed, so
The process returns to the main routine through subroutine 7 of step @ and subroutine 10 of step a.

Next, the subroutine 10 shown in FIG. 21 will be explained. This subroutine 10 is included in the standby routine of step (2) and calculates and displays the total number of copies.

First, check FG51=1 in step ■, and
If 51=1, in step ■, [CTJBTC)≧(C
TJ BPC). F() in step ■
If 51=1, then (CTJ BTC)≧(C
If the job is not TJBPC), that is, if all the input jobs have been executed, in step (2), an O is entered and displayed in the total copy counter, and the process returns to the main routine.

Stella 6 I) (CTJBTCI≧(C'rJBPC)
If so, set R2 to O and set the value of CTJBTC to R1.
After entering, (Rt) = (CTJBPC) is checked (steps σ) to ■). At step ■ (Rx) = (
CTJBPC) (1 and the multiplication value of the original number set value and the copy number set value in the memory specified by (R1) in step ■■ is added to (R2), and in step 0) (
After entering the value of R1)-1=2Rt, return to step C). Steps ~) are repeated, and in step ■ (R
1) = (CTJBPC), in step (), (R
Add the multiplication value of the set value of the number of original sheets in the memory specified in step 1) and the set value of the number of copies per copy to (R2), and add the actual value of the number of original sheets in the memory specified in (R1) in step The value multiplied by the actual copy number value is subtracted from (R2), and in step 2, the resulting value (R2) is entered and displayed in the total copy one copy counter, and then the process returns to the main routine.

Next, subroutine 11 shown in FIG. 22 will be explained.

This subroutine 11 determines whether the conditions for starting copying are met in the multi-job mode, prohibits the start of copying if the conditions are not met, and displays the determination result.

First, in step φ), check that FGI 2=1,
If FGI2=1, it is checked in step 6) whether the first document set detection means 24 is ON. If the first document set detection means 24 is not ON, it is checked in step ) whether the copying operation is interrupted, and if the copying operation is not interrupted, the FGI 11 is set to 1 (step )). The determination as to whether or not the copying operation is interrupted is made, for example, by checking the number of copies set = the number of copies to be executed or by checking that the stop flag = 1.

The reason why step Φ■ is provided is to prevent the print key 47 from being displayed in red when the first document set detection means 24 is OFF when the copying of the final document is temporarily interrupted. Copy operation interruption means contact glass 7.
This is a case where there is document 0 on a, the number of copies to be executed has not reached the number of copies set, and the copying operation is stopped.

If the first document set detection means 24 is ON in step Φ) and the copying operation is interrupted in step 6),
It is checked whether the pressure plate opening/closing detection means 30 is OFF (step Φ)). Pressure plate opening/closing detection means 30 is OFF
', go to step Φ) and set FGlt t to 1,
Further, if the pressure plate opening/closing detection means 30 is ON, step
Then set FQllll to 0 and go to step ■■.

Next, in step 6α, F'G51=1 is checked, and F'G51=1 is checked.
If G51 is not 1, step ② Boil FG112 is set to 1. If FG51=1 at step @, step ■)
Check that [CTJBTC]≧[CTJBPC]. (If CTJBTCI≧(CTJBPC), the input job is being executed, so go to step) and set FQ112 to 1. [CTJBTC]≧(CTJ
If BPC: 1, some of the input jobs have not been executed, so FGI 12 is set to 0 in step φ). If FGI 2 is not 1 in step ■ above,
In step (2), FGI 11 and FGI 12 are set to 0.

Next, check FGI 11=1 in step ■),
If FGI11=1, the print key 47 is displayed in red, meaning that copying is impossible, and the process returns to the main routine in step (2). FGI with Ste/Tub ■)
If 11=1 is not true, then FGI 12=1 is checked in step Φ). If FQ112=1, the process goes to step G and the print key 47 is displayed in red. FGI 12=
If the print key 47 is not 1, the print key 47 is displayed in green indicating that copying is possible, and the process returns to the main routine.

Next, subroutine 12 in FIG. 23 will be explained.

This subroutine 12 is included in the standby routine of step (2), and automatically sets the sort mode or stack mode based on the document number set value in the multi-job mode.

First, check FGI 2=1 in step CQ,
If FG12 is not 1, it is not the multi-job mode and the process returns to the main routine. If FG12=1,
In step @, check [Original sheet number set counter] = 1. If [Original sheet number set counter] = 1,
Reset the sort mode, i.e. set FGI 31 to 0.
) and set the stack mode, i.e. FG13
2 as 1), then outputs a mode signal to the sorter 3 (steps Φ to e) and returns to the main routine.

If the [original sheet number set counter] is not 1 in step O, then the [original sheet number set counter] is checked for 1 in step (■). [Original sheet number set counter] If it is 1, it is necessary to reset the stack mode.
132 to O), the sort mode is set (ie, the FGI 31 is set to 1), and then a mode signal is output to the sorter 3 (steps ■), ■T3), ■). If the [original number set counter] is not 1 in step ■), the input value of the number of originals is O, so reset the sort mode and stack mode and output a mode signal to the sorter 3 (step □□□). ■)).

Next, subroutine 13 shown in FIG. 24 will be explained.

This subroutine 13 is included in the standby routine of step (2) and accepts the print key 47.

First, it is checked in step CD whether or not the print key 47 is ON, and if the print key 47 is ON, it is checked in step (2) whether or not the print key 47 is displayed in red. In step ■), print key 47 is set to O.
If not N, or if the print key 47 is displayed in red in step (2), the process returns to the main routine.

If the print key 47 is not displayed in red in step (), that is, it is displayed in green, FGI 2 is
Check =1. If FGI2=1, it is checked in step C) whether the copy operation is interrupted. If the copy operation is interrupted, the copy start flag FG1 is set.
41 is set to 1, and the print ON signal is output to the ADF2 (steps (iJJ, σyu). Return to the main routine. At step), the copy operation is interrupted and the night is started.
Without setting the copy start flag FGI 41 to 1, output the print ON signal to the boil ADF 2 in step C. If FGI 2 is not 1 in step σ) above, the copy start flag FGI 41 is not in multi-job mode.
After setting the value to 1, output the print ON signal to the ADF 2 (step 3).

If the copy operation is not interrupted at step ■), step ■)
outputs an ON signal (print) to the ADF 2, and as described later, this signal turns the ADF 2 ON and transports original 0 or partition paper d, and it is determined that the one being transported is original 0. A copy start signal is output to the electronic copying machine 1 only to set the copy start flag FGI 41 to 1, and the copy start signal is not output in the case of partition paper d.

If the copy operation is interrupted in the above step (■), there is original 0 on the contact glass 7a, so the
As soon as 7 is turned on, copy start flag FGI
41 is set as 1.

Next, the subroutine 14 shown in FIG. 25 will be explained.

This subroutine 14 is included in the standby routine of step (2) and processes the copy start signal from the ADF 2 or the signal from the partition paper detection means 25.

First, check FGI 2=1 in step ■, and
If G12=1, the copy start flag FG141=1 is checked in step Φ. If the copy start flag FG141 is not 1, the presence or absence of a partition paper detection signal is checked in step @.

When there is a partition paper detection signal in step ■■, the buzzer 10

(Step ■■~$) o If [Original sheet number set counter] = [Original sheet number execution counter] in step @, the number of original sheet discrepancy indicator 69 will be displayed in step ■■
Turn ON, step ■Boiled copy start flag FG
After returning to the main routine after setting I41 to 0 step (■) to σyu, the reason why the number of originals discrepancy display 69'1i is turned ON is because the original 0 set has not been copied. Since the partition paper d came when there was something else, (1) If you mistakenly set the number of originals O, which is smaller than the number of originals you entered, in the ADF2,
(2) Transfer the same number of originals as the input number of originals to the ADF2.
(3) When the number of originals set in the ADF 2 is erroneously greater than the number of originals set in the ADF 2.

Above step ■ Boiled copy start flag = 1),
Alternatively, if there is no partition paper detection signal in step ■■, the presence or absence of a copy start signal from the ADF 2 is checked in step ■Φ. When there is a copy start signal from ADF2 in step @, [original sheet number set counter] = [
Check the [Original Sheet Number Execution Counter] and if [Original Sheet Number Set Counter] = [Original Sheet Number Execution Counter],
To reset the copy start signal from the ADF 2, go to step (2) and turn on the number of originals discrepancy display 69. In such a case, the reason why the number of originals discrepancy indicator 69 turns ON is because (4) you mistakenly set more originals than the input number of originals in ADF2, and (5) the number of originals set in ADP2. This may also happen if you mistakenly enter a smaller number of originals. 'If FQI 2 is not 1 in step @ above, the presence or absence of a copy start signal from ADF 2 is checked in step CΦ. If there is a copy start signal from ADF2 at step @, or if [original sheet number set counter] = [original sheet number execution counter] at step ), copy start flag FG1 is sent at step φΦ.

Check whether it is. If the multi-job mode flag FG12 is not 1 in step ■■, step ■■)
Set the 8ADF' mode with . Therefore, 5AD
The second document set detection means 28 for detecting document 0 on the document insertion table 20 at F'20' is ON, and the ADF 2
When the first document setting detection means 24 that detects document 0 on the document setting table 2a is ON, ADF mode is set if the multi-job mode is selected, and ADF mode is set if the mode is not the multi-job mode. set.

Next, subroutine 21 shown in FIG. 32 will be explained.

This subroutine 21 includes steps ■, ■, ■, [phase]
It is included in the original document feeding control routine, and outputs a partition paper detection signal and a copy start signal to the electronic copying machine 1.

First, in step ■■, it is checked that (TPC)≧R. This TPC is a timing pulse counter that counts the number of pulses output from the encoder 19. The above R is a predetermined value from when the partition paper d is fed by the ADF 2 from the time when the paper feed starts until the partition paper detection means 25 detects the first hole d1 of the partition paper d and the next hole d1. This is the number of pulses output by the encoder 19 up to this point.

If [TPO]≧R in step ■■, step σ)
It is checked whether the partition paper detection means 25 is ON or not. The partition paper detection means 25 is turned ON even if it detects either the partition paper d or the document 0. Step ■ When the boiled partition paper detection means 25 is turned ON, step ■■
Then, AFG21 is set to 1 and the process returns to the main routine. This AFG21 is a flag for detecting the partition paper d. Next, when the partition paper detection means 25 is turned off in step (2), AFG21=1 is checked in step (2). If it is AP'G21-1 in step ■Φ, the partition paper detection means 25 has detected the hole d1 in the partition paper d, so in step ■■, AFr↑22 is set to 1 and the process returns to the main routine.

This AF'G22 is a flag for detecting the hole d1 in the partition sheet d. If AFG21 = 1 in step ■■,
Since the partition paper detection means 25 does not detect partition paper d or document 0, the process returns to the main routine.

Next, if [TPC]≧R in step ■■, it is checked that [TPO]=H in step ■■.

[TPO] = R, AFG22 in step ■)
Check =1. AFG22 in this step qD
If =1, it means that the partition paper d is being fed by the ADF'2, so the partition paper detection signal is output to the electronic copying machine 1 in step (Y), and the AFG21 and AP'G22 are 0 to return to the main routine.

If AFG22 is not 1 at step 6, step φ)
Checks that APG21=1. AF at step O
If G21 = 1, it means that the ADF 2 is feeding document 0, so in step 2, a copy start signal and a document count signal are output to the electronic copying machine 1, and in step φ2 (.

If AFG21 = 1 in step ■), step φ
In step (3), it is checked whether the second paper feed detection means 27 is ON. At step σ, the second paper feed detection means 27 is set to O.
If not, the partition paper d or document 0 is jammed, so the ADF jam flag is set to 1 in step 2 and the process goes to step 3. Step (Boiled second paper feed detection means 2
If 7 is ON, the process returns to the main routine.

Next, the subroutine 22 shown in FIG. 33 will be explained.

This subroutine 22 is included in the classification operation control routine of step [phase], and outputs a copy ejection signal to the electronic copying machine 1 when the copy ejection sensor 37 of the sorter 3 is turned on.

First, it is checked whether the boiled copy ejection sensor 37 of the step is ON. If the copy ejection sensor 37 is ON, 5FGI 1=1 is checked in step (3). This 5FG11 is a flag that detects whether the copy ejection sensor 37 is turned on. Step (5FGI in Φ
If 1 is not 1, set 5FGI 1 to 1 and output the electronic copying machine IK copy ejection signal (step φα, ■■)
Return to main routine. If the copy ejection sensor 37 is not ON in the above step Φ, 8FG11 is set to O in step Φ, and then the process returns to the main routine. If 8FG11=1 in step ■■, the process returns to the main routine.

Next, the subroutine 23 shown in FIG. 34 will be explained.

This subroutine 23 is included in the standby routine of step ◎ and controls the job partition display 39 based on the 1-job hand signal from the electronic copying machine 1.

First, in step ■■, the presence or absence of the 1 job end signal is checked. When the 1-job command signal is received, the job partition display 39 corresponding to the last bin 3e of the job whose boiling execution has been completed is turned on in step 2, and then the process returns to the main routine. If there is no job end signal at step ■■, the process returns to the main routine.

Next, the subroutine 24 shown in FIG. 35 will be explained.

This subroutine 24 is included in the final processing routine of step O, and processes the all-job end signal from the electronic copying machine 1.

First, the presence or absence of an all-job end signal is checked in step Φ, and if there is an all-job end signal, it is checked in step 2 to see if the bin copy paper sensor 38 is ON. If the bin copy paper sensor 38 is not ON, all job partition displays 39 are turned OFF in step φ■ and the process returns to the main routine. The all job end signal is when the multi job mode is canceled,
It is output when the job cancel key 68 is pressed. Therefore, even if the multi-job mode is canceled, the job partition display 39 is not turned OFF immediately, but after removing the copy paper P from all the bins 3e of the sorter 3, the job partition display 39 is turned OFF and the copy paper is removed. I am trying to understand the boundaries between P's jobs. If there is no all-job end signal in step 2, or if the bin copy paper sensor 38 is OFF in step 2, the process returns to the main routine.

Next, subroutine 25 shown in FIG. 36 will be explained.

This subroutine 25 includes the standby routine of step
This routine is included in the copying operation control routine of step (2) and the final processing control routine of step 0, and is used to check for troubles in the electronic copying machine. Troubles include jams in original 0 and copy paper P, abnormalities in various devices, and the like.

First, in step O, it is checked whether there is any trouble. If there is no problem, return to the main routine.

If there is a problem, trouble flag FGT is displayed in step ■■.
After setting RABL to 1, return to the main routine.

In the illustrated embodiment, one sorter 3 is connected to the electronic copying machine, but a plurality of sorters can be connected to the electronic copying machine 1. When connecting multiple sorters to the electronic sorter, the maximum number of sorter bins, N, is determined in step 2 of subroutine 7 in FIG. 18, depending on the number of sorters and the number of bins in each sorter. All you have to do is change.

Effects According to the present invention, a first job mode in which a plurality of originals with the same copying conditions are successively copied and a multi-job mode in which multiple groups of originals with different copying conditions are successively copied are selectively set. In the case of an electronic copying machine that can perform automatic copying, it is possible to prevent erroneous mode switching during recovery work when a trouble occurs.
