Next, based on FIGS. 7 to 10, create a multi-job
We will explain the various operation keys and indicators used during the mode.

The multi-job key 52 is used to set the multi-job mode.

The number of originals key 56 is used to input the number of originals for one output in the multi-job mode. Original number key 56
When is pressed, the original sheet number set counter display 64 flashes, and then the value input using the numeric keypad 48 is counted by the original sheet number sector counter provided in the microcomputer 104.
The number of original sheets is also displayed on the set counter display 64. In this case, in order to change the value input 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 number of copies key 57 is used to input the number of copies of one external tooth in the multi-job mode.

When the number of copies key 57 is pressed, the number of copies set counter display 49 flashes, and then the value entered using the numeric keypad 48 is counted by the number of copies set counter provided in the microcomputer 104. The number of copies is displayed on the set counter display 49. In this case, numeric keypad 48
To change a value that has been input repeatedly, 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 sheet number set counter and the copy sheet number set counter into the RAM of the microcomputer 104 in the multi-job mode.

The set number confirmation key 66 is used to display the contents of the job input at the time of multi-job selection. 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 the number confirmation key 66 is pressed at this time, The number display value is incremented to "2" and the contents of the second job are stored in the RAM.
is read from 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.

Job cancel key 68 has four functions.

The first function of the job cancel key 68 is to clear all 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 then stop the execution of the job. When the job cancel key 68 is pressed when the cocoon 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 count set counter and copy sheet count 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.

61b is turned on, and the numeric key press indicator 62'f is turned on.
t: After turning OFF [step [phase]] return to the main routine.

If Fe32 is not 1 in step @, it is checked in step [phase] whether or not the 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
After setting Fe12 to 1 (step @, [phase]), return to the main routine.

Next, subroutine 5 shown in iC 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 @, 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 is -58dKON, check Fe22 = 1, and if Fe22 = 1, check [1 copy number set counter] 20 [Step [phase],
]. If FG22=1, then check for Fe32=1 in step @; if Fe32=1, go to step O; and if Fe32=1, return 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] = 0 in step [phase]. If [copy sheet number set counter] is 20 or [original sheet number set counter] = O, the process returns to the main routine.

[One copy set counter] = not 0, and
[(Manuscript number set counter] = 0, if (C
The value of the copy number set counter and the value of the original number set counter are stored in the memory specified by TJBPT) and displayed (step @).

Next, Fe12 and Fe12 are set to O, input key press indicators 51a, 61b, numeric key press indicator 62, and number of copies key press indicator 60a.

Turn 60b OFF (step 0. [phase]) 6th F
After setting e21 to 1 (CTJBPT, check l=M (step [phase], 0). This M is the maximum number of items that can be input in multi-job mode. (C
If TJBPT)=M, (CTJBTC) (checks M (step)).

In step [phase], (CTJBTC) (if not M) If the child, that is, the maximum input value is larger than M, it is impossible to input job data, so subroutine 10 of step [phase] At step [CTJBTCI (M), job data can be input, so at step [phase] set [CTJBTCI+1], then go through subroutine 10 of step [phase] and return to the main routine. Return to 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 original Japanese price key press indicators 59a and 59b, check [CTJBPT]>[CTJBTC] (step [stock], ■). This is a check to see if the displayed job has been input. (CTJBP
T)) (CTJBTC), the displayed job has not been input yet, so the value of CTJBPT is entered into CTJBTC and the value is passed through subroutine 7 to display the number of original sheets on the confirmation display 71 or the number of copies. It is checked whether the number confirmation display 72 is ON (steps [phase] to [phase]).

If the number of original sheets confirmation display 71 or the one-page number confirmation display 72 is not ON in the above step [phase], job input is possible, so (CTJBPT) +1 is set and the number of original sheets set counter is set. O is entered and displayed, 0 is entered and displayed in the number of copies set counter, and the process goes through subroutine 10 and returns to the main routine (steps [phase] to [phase]n). If the number of copies set confirmation display 71 or the number of copies set number confirmation display 72 is ON, it is impossible to input a job, and the process returns to the main routine through the subroutine 10 of step .

At the above step [phase] (CTJBPT)) (CTJBT
If it is not C), the displayed job has already been input, so go through the entire subroutine 7 and check whether the number of original sheets placed confirmation display 71 or the number of copies placed number confirmation display 72 is ON. Check (step [stock], (■).

If the original number confirmation display 71 or copy number error detection display 72 is ON in step O, it is impossible to input the job, so subroutine 10 of step [phase]
and returns to the main routine.

If the original number confirmation display 71 or the copy number confirmation display 72 is not ON in the above step (), it is specified by (CTJBPT) in step () after setting it to (CTJBPT, 1+1) in step (). 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 IO of step [phase].

As described above, when the input key 58t is turned on, the data of the displayed job is not only stored in the memory, but also the data of the next job is prepared for input.

Next, subroutine 6 shown in FIG. 17 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 ■, check that Fe51 = 1, that is, check whether there is an input job.
If Fe51 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 Fe51=1, it is checked whether or not the number confirmation key 66 is ON, and if it is ON, Fe61=1 is checked (steps ◯, ◯). If Fe61=1, the process returns to the main routine. If Fe61 is not 1, set Fe61 to 1 (CTJBPT)) (C
TJBTC) (step O9■). [
CTJBPT))l:CTJBTC) means checking whether the displayed job has been input. (CTJBPT)) (CTJB-TC), the displayed job is a job that has not been input, so the next job is also a job that has not been input, so (CTJBPT) is set to t-1 ( Step (e
). Next, in step O, Fe12 and Fe22 are set to 0, and in step O, the contents of the memory specified by (CTJBPT) are set to the copy number set counter, copy number execution counter, original number set counter, and original number execution counter. Enter and display. Next, in step O, the numeric key press indicator 62, input key press indicators 61a, 61b
And one copy number key press indicator 60a, 60b is set to O.
After setting it as FF, check that [original sheet number set counter] = 0 in step O. [Original sheet number set counter] When it is 20, the original sheet number key press display 59a, 59b
is turned ON (step Q), and if [original sheet number set counter] is not 0, the original sheet number key press indicator 59a,
59b is turned OFF (step ■) and returns to the main routine.

In the above step (), (CTJBPT)) - (CTJBT
If it is not C), the displayed job has been input, so in step Φ), set ('CTJBPT)+1, and then in step O, check [CTJBPT]>[CTJBTC). At step ■ (CTJBPT)) (C
TJBTC), pass through step ()f and step O
Then, the contents of the mesori specified by [C, TJBPT] are entered into the one-copy number set counter, the one-copy number execution counter, the original number set counter, and the original number execution counter and are displayed. In step () (CTJBPT) > (CT
JBPC), set Fe12 and Fe12 to 0, and display 0 in the document number set counter, and
Enter 0 in the copy number set counter and display it (
Steps () to e) Go to step ().

If the number confirmation key 66 is not ON in the above step, F
Set e12 to O and then check Fe42=1 (
Step ■, ■)). If Fe42=1, it means that the numeric keypad 48 was turned on while the number confirmation key 66 was pressed, so set FG42 to 0, (CTJBPT))(
CTJBTC) (steps ■, ■).

(CTJBPT) in this case is the value input using the numeric keypad 48. in step () (CTJBPT)) (
CT'J B T C), the displayed job is an uninput job, so the value of CTJBTC is

If FG91 is not 1 in step (2), Fe12 is set to 1, and then it is checked whether or not the document number mismatch display 69 is ON (steps (), (2)). If the original number mismatch display 69 is SON, after turning off the original number mismatch display 69, it is checked whether the values of the original number execution counter and the number of copies counter are 0, that is, Check whether the displayed job is yet to be executed (step 9.■). In step φ), the number of original sheets and the number of copies executed are counted;
If it is 0, the displayed job has not yet been executed, so subroutine 7 of step ■ and step () are executed.
subroutine l.

and returns to the main routine.

If the values of the original sheet count execution counter and the copy sheet count execution counter are not 0 in step ■, the displayed job has already been executed, so stop the execution of this job and set (CTJBPC) +1 in step O. After that, a 1-job end signal indicating that the execution of the job has been completed is output to the sorter 3.

Then in step () (CTJBPC) ((CTJBTC
) Check. (CTJBPC) ((CTJBT
In the case of CI, the number of jobs in the execution method is greater than the maximum number of jobs entered, that is, there are no remaining jobs, so subroutine 7 of step () and subroutine of step 10 to return to the main routine.

If the step is (CTJBPC) ((CTJBTC), the number of jobs in the execution method is smaller than the maximum number of entries entered, so put the value of CTJBPC in CTJBPT (step (]) and then in [CTJEPT). The set value for the number of original sheets and the set value for the number of copies per sheet in the specified memory are entered into the original sheet number set counter and the one copy sheet number set counter and displayed. Step (¥C), step O subroutine 7 and step O subroutine 10 are passed. and return to the main routine.

If the number of originals discrepancy display 6 is not ON in the above step (), in step O, (CTJBTC) ≥ (CTJBP
Check T). In step () (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 check whether the values of the original number execution counter and the copy number execution counter are O. In other words, check whether the displayed job is before execution (
Step ■).

In step (), if the values of the original sheet count counter and copy one sheet execution counter are 0, the displayed job has not yet been executed, so the set value of the number of original sheets specified by (CTJBPT, !) and the set value for the number of copies per copy, leaving the memory blank (and fill in the contents of the next memory one by one (step ■).

Make a check of (CTJBTC) = O in step (). If (CTJBTC) = :0 in step O, (CTJBTC) is set to -1 in step (), and if (CTJBTC) is +0 in step (■), FG51 is set to O.
After that, the contents of the memory specified by [CTJBPT] are entered into the copy sheet number set counter and the original sheet number set counter and displayed (step (9).Next, the numeric key press indicator 62 and the input key press indicator 61a are displayed. .

BPC), the input job is being executed, so subroutine 7 of step ■ and step ()
The program returns to the main routine through subroutine 10.

Next, the subroutine 1o 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 (),
If FG51=1, step ■ [CTJBTC)≧
Check (CTJBPC). F at step ■■
If e21 = 1, then (CTJBTC)≧(
CTJBPC), that is, if all the input jobs have been executed, an O is entered and displayed in the total copy counter at step (2), and the process returns to the main routine.

In step ■, if (CTJBTC)≧(CTJBPC), set R and z to O, and set the CTJBTCO value to 1 (+
1, then check (Rz)=(CTJBPC) (steps ~). At step ■ (R1) = (
CTJBPC), in step ■, the multiplication value of the original number set value and the copy number set value in the memory specified by (R1) is added to (R2), and in step ■, (Rx) is added.

TJBPC), in step O, the multiplication value of the original number cent value in the memory specified in (R1) and the set number of copies per copy value is added to (R2), and in step (), (R1) is added.
Subtract the multiplication value of the actual number of original sheets and the actual number of copies in the memory specified by (R2), and step
The resulting value (R2) is entered into the total copy counter and displayed, and then the process returns to the main routine.

Next, the 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 O, check FGI 2=1, and
If GI2=1, it is checked in step O whether or not the first document set detection stage 2475 is ON. If the first document set detection means 24 is not ON, it is checked in step (2) whether or not the copying operation is interrupted, and F'Gx 11 is set to 1 if the copying operation is not interrupted (step (2)). The determination as to whether or not the conocopy 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 (2) 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 7a.
This is a case where there is an original 'aO' on top of , 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 (2) and the copy operation is interrupted at step (),
Check whether the pressure plate opening/closing detection means 30 is OFF (step ○).The pressure plate opening/closing detection means 30 is OFF'
Then, set the step number Ii"Gxtx to 1,
Further, if the pressure plate opening/closing detection means 30 is ON, step ○
Then set FGllll to 0 and go to step ■.

Next, in step ■, check FG51=1, and Fe2
If 1 is not 1, the FG112 is set to 1 in step O. If FG51=1 in step ■, then in step O (CT
JBTC) ≧ [CTJBPC). (C
If TJBTC)≧(CTJBPC), the input job is being executed, so go to step ■FG11.
Let 2 be 1. If (CTJBTC)≧(CTJBPC), some of the input jobs are not being executed, so FGI 1 z20 is set in step O.If FGI 2 is not 1 in step ■ above, FGI is 11 and FGI 12 are set to 0.

Next, in step O, check FGI 11=1 and F
If GI 11=1, print key 4 is pressed at step O.
7 is displayed in red, meaning that copying is impossible, and the process returns to the main routine. FGI 11 = at step O
If it is not 1, check FGll2=I in step ①. If F'GI 12=1, the process goes to step O and the print key 47 is displayed in red. If FGI12 is not 1, the print key 47 is displayed in green indicating that copying is possible in step O, and the process returns to the main routine, and then the subroutine 12 of FIG. 23 is executed.

This subroutine 12 is included in the standby routine of step (2) and automatically sets the print mode or stack mode based on the i-manuscript number sector value in the multi-job mode.

First, check F, G12 = 1 in Step Silver),
If FG12 is not 1, it is not the multi-job mode and the process returns to the main routine. If k' G12=1, in step O, it is checked that [original sheet number set counter]=1. If [Original sheet number set counter] = 1, the document mode will be changed seven times, that is, F'G131.
1o), and set the stack mode to the PC
x132 to 1), then outputs a mode signal to the sorter 3 (step (9%O)) and returns to the main routine.

If [original sheet number set counter] is not equal to 1 in step O, it is checked in step O that [original sheet number set counter] >1. [Original sheet number set counter]〉l,
Reset the stack mode (FGI 32 to O) and set the stack mode to L (f, F'GI).
31 as 1), and then outputs a mode signal to the sorter 3 (Stella y' (f3), O). step()
If [original sheet number set counter]>1 is not satisfied, the input value of the number of original sheets is O, so the stack mode and the stack mode are reset and a mode signal is output to the sorter 3 (steps O, O).

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

This subroutine y13 is included in the standby routine of step (2) and accepts the print key 47.

First, in step O, it is checked whether the print key 47 is ON, and if the print key 47 is ON, in step O, it is checked whether the print key 47 is displayed in red. and print key 47 is O.
If not N, or if the print key 47 is displayed in red at step O, 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 = 1 in step O.
Check. If FGI2;1, step O
Check whether the copy operation is interrupted. If the copy operation is interrupted, the copy start flag FGI 41 is set to 1, a print) ON signal is output to the ADF2, and then
Step 9. σ)), return to the main routine. If the copy operation is not interrupted at step ■, AI at step O without setting the copy start flag FG141 to 1)
Outputs the pudding) ON signal to F2. If FGI 2 is not 1 in step O above, it is not multi-job mode, so output the print ON signal to ADF'2 while setting copy start flag FGI 41 to 1 (step O
.

()).

If the copy operation is not interrupted at step (), the stack ()
outputs a print ON signal to ADF2, and as described later, this signal turns ADP2 ON and transports original 0 or partition paper d, and only when it is determined that the one being transported is original 0. A copy start signal is output to the electronic copying machine 1 and the copy start flag FGI 41 is set to 1, but the copy start signal is not output in the case of partition fad.

If the copying operation is interrupted in the above step (), the copy start flag FGI is activated as soon as the print key 47 is turned on because the document 0 is on the contact glass 7a.
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 in the evening, the copy start signal from the person DF 2 or the signal from the partition paper detection means 25 is filled in six times.

First, check FGI 2=1 in step (),
If FG12=1, the copy start flag FGI41=1 is checked in step (). If the copy start flag FGI 41 is not 1, the presence or absence of a partition paper detection signal is checked in step O.

When there is a partition paper detection signal in step O, the buzzer 109
is turned ON, and after resetting the partition paper detection signal, the [manuscript sheet number set counter] = [original sheet number execution counter] is checked (steps ① to e). If it is not [original sheet number set counter]; [original sheet number execution counter] in step O, the number of original sheet discrepancy indicator 69 is turned ON in step O.
and set the copy start flag FG141 in step ().
't-0 and then return to the main routine. The reason why the number of originals mismatch display 69fc is turned on in step (D) after going through steps () to O is because partition paper d came when there was one of the set originals 0 that had not been copied, If you accidentally set the number of originals 0, which is smaller than the number of originals, in the ADF2, (2)
When the same number of originals 0 as the input number of originals is set in ADF2, but multiple originals 0 are stacked and sent at the same time, that is, when original O is sent by lightning, and (3) the number of originals added to ADF'2 This is a case where you accidentally input the number of originals that is larger than the number of originals.

Copy start flag FG141 = 1 in step O above
If yes, or if there is no partition paper detection signal in step (), the presence or absence of an ADF 2-color copy start signal is checked in step O.

When there is a copy start signal from the ADF2 in step (), the [Original sheet number set counter] = [Original sheet number execution counter] is checked, and the [Original sheet number set counter]
= [Original number execution counter], the copy start signal from the ADF2 is reset. Steps O, (JJ
f3)), go to step (D and turn on the number of originals mismatch display 69. The reason why the number of originals mismatch display 69 turns on in this case is that (4J) This is the case where the original number of original sheets (8!0) is set in the ADF 2, and the case where the number of original sheets (5J) which is smaller than the number of original sheets set on the ADF 2 is inputted by mistake.

If FGI 2 is not 1 in the above step ■, step O
The presence or absence of the copy start signal from ADF 2 is checked. If there is a copy start signal from ADF 2 in step O, or if [original sheet number set counter] = [original sheet number execution counter] in step O, copy start flag FGI 41 is set to 1 in step O.
to return to the main routine. If there is no copy start signal from the ADF 2 in step (), the process returns to the main routine.

If there is no copy start signal from Al) F'2 in the above step (), then in step O it is checked that FG151=1. If FGI s 1 is not 1, it is checked in step () whether or not the original is the last sheet. step()
If FGI 51=1, then F in step Φ)
If draft A is not the final paper, the process returns to the main routine.

Next, in step (), if the original is the final paper, step O
Then, it is checked whether [original sheet number set counter] = "[original sheet number execution counter]". At step O
Original sheet number set counter] = [Original sheet number execution counter]
Otherwise, go to step O and display the number of originals discrepancy indicator 6.
Turn on 9. The reasons for turning on the document number mismatch display 69 in such a case are as shown in (1) to (3) above.

If [original sheet number set counter]=[original sheet number execution counter] in the above step () or O, FGI 51=1 is checked in step O. FGI 5
If 1 is not 1, set FGI 51 to 1 and (CTJBP
C) +1, and after outputting 1 job end signal to sorter 3, (CTJBTC) ≧ (CTJBPC) (D?z
/f, jru (steps 0-0)). If FG151=1 in step O above, go to step (strong).

Sf Tsubu () (CTJBTC) ≧ (CTJBPC)
, some of the input jobs have not been executed, so in step (), change the value of CTJBPC to CTJBP
After inputting the number of originals and the number of cents per copy in the memory specified in step (D [CTJBPT)] to the original number set counter and the number of copies set counter, the main routine starts. Return to. In step () (CTJBTC) ≧ (CT
JBPC), the input job is being executed and the process returns to the main routine.

If the first document set detection means 24 is ON, the ADF mode is set if the multi-job mode is present, and the ADF mode is set if the first document set detection means 24 is not in the multi-job mode.

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

This table table 21 is included in the original feed control routine of steps ①, ②, ◎, and ◎, 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 (TPCI≧normal). This TPO is a timing pulse counter that counts the number of pulses output from the encoder 9. The above R is when feeding the partition paper d with the ADF 2. This is the number of pulses that the encoder 19 outputs from the start of paper feeding until a predetermined time point from when the partition sheet detection means 25 detects the first hole d1 of the partition H1d to when it detects the next hole d1.

If (TPO)≧K is not found in step (2), it is checked in step () whether or not the partition paper detection means 25 is ON. This partition paper detection means 25 detects either the partition paper d or the original O and becomes 4ON. When the partition paper detection means 25 is turned ON in step ( ), the AFG 21 is set to 1 in step C and the process returns to the main routine.

This AFG21 is a flag that detects the partition ID. Next, when the partition paper detection means 25 is turned off in step (), AFG21 =1 is checked in step (). If APG21=1 in step (), the partition paper detection means 25 has detected the hole d1 of the partition paper d, so
At step O, AFG22 is set to 1 and the process returns to the main routine.

This AFG22 is a flag that detects the hole d1 of the partition H1d. If AFG21 is not 1 in step O, the partition paper detection means 25 has not detected the partition ID or original O (), so the process returns to the main routine.

Next, in step (), if (TPCI≧K), (TPC) is checked in step O.

If (TPC) = 几, then in step C) AFG22 =
Check 1. At this step O, AFG22=1
Then, the partition paper d is being fed by the ADF'2, so a partition paper detection signal is output to the electronic copying machine 1 at step ○, and the AFG21 and AF' are sent at step C).
Set G22 to O and return to the main routine.

If AFG22=1 is not determined in step (), AFG21=1 is checked in step O. λFG at step O
21 = 1, it means that document 0 is being fed in ADF 2, so in step 2, a copy start signal and a document count signal are output to electronic copying machine 1, and step (
).

If AFG21 is not 1 in step O, it is checked in step O whether or not the second paper feed detection means 27 is ON. In step (), the paper feed detection means 27 of jg2 is turned on.
Otherwise, since the partition MD or original aO is jammed, the DF jam flag is set to 1 in Stella AS) and the process goes to step O. In step (), the 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, in step (■, it is checked whether the copy ejection sensor 37 is ON or not. If the copy ejection sensor 37 is ON, 8FG11=1 is checked in step (). This SF'GII is sensor 37
This is a flag that detects the ON of . 5FG in step ()
If I1 is not 1, 8FG11 is set to 1, and the electronic copying machine IK:rbee ejection signal is output (step (),
()) Return to the main routine. If the copy ejection sensor 37 is not ON in step (3) above, 8FG11 is set to O in step C), and then the process returns to the main routine. If 5FG11=1 in step (), the process returns to the main routine.

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

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

First, in step C), the presence or absence of the 1 job end signal is checked. When there is a 1-job command signal, the job partition display 39 corresponding to the last job 3e of the job whose execution has ended in step O is turned ON, and then the process returns to the main routine. If there is no job end signal at step O, 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 @ and processes the all-job end signal from the electronic copying machine 1.

First, in step O, the presence or absence of the all-job end signal is checked. If the all-job end signal is present, in step O, it is checked whether the pin copy paper sensor 38 is ON. If the pin copy paper sensor 38 is not ON, all job partition indicators 3 will be
Turn 9 OFF and return to the main routine. The all-job end signal is output when the multi-job mode is canceled and when the job cancel key 68 is pressed.

Therefore, even if the multi-job mode is canceled, the job partition display 39 is not immediately turned OFF' and the sorter 3
After removing the copy paper P from each bin 3e, the job division display 39t is turned OFF so that the job division of the copy paper P can be seen. If there is no all-job end signal in step O, or if the pin copy paper sensor 38 is OFF in step O, the process returns to the main routine.

In the illustrated embodiment, one sorter 3 is connected to one copying machine, but a plurality of sorters can be connected to the electronic copying machine 1. When a plurality of sorters are connected to the electronic copying machine 1, step 1 of subroutine 7 in FIG.
In this case, N, which is the maximum number of sorter bins, may be changed.

Effects According to the present invention, it is possible to continuously copy multiple groups of originals with different copying conditions, and in this multi-job mode, the state of the automatic document feeder and whether or not the copying operation is interrupted is determined. can be used to control copy operations.
