Abstract

PURPOSE:To copy continuously originals different in copying condition and to display the remainder of set originals by subtracting a stored original number set value from a maximum original set number and adding a stored original number execution value to this subtraction result to calculate the value of the remainder of set originals and displaying this calculated value. CONSTITUTION:When an original number key 56 is depressed in the multijob mode, the value inputted with a ten key is counted by the number set counter of a microcomputer (MP) 104 and is stored in a storage device (RAM) and is displayed on a display device 64. When a copy number key is depressed, the copy number is displayed on a display device 63 similarly. Meanwhile, the count- ed value of the original number execution value is stored in a storage means of the MP104 and is displayed on the display device 50. When a remainder confirming key 67 is depressed, the MP104 subtracts the stored value of the original number set value from a maximum original set number and adds the stored value of the original number execution value to the subtraction result to calculate the value of the remainder of set original, and this calculated value is displayed on a display device 49.

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 a multi-job code.

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 you press , the number of original sheets is displayed on the counter display 64. 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 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 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 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.
1 position confirmation key 66
is used when displaying to confirm the contents of the job input in multi-job mode. For example, if the contents of the first job (the number of originals set and the number of copies set) are displayed, the number display 544 will display "1
" is displayed, 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 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.

Copy start flag FG 141 =
If it is 1, the process goes to step (2), a copying start routine. This copying operation start routine consists of subroutines 16.18. Next, the process goes through the original feed control routine in step (2) and then goes to the copying operation control routine in step (2). This copying operation control routine consists of a subroutine 17. Next, through the document feed control routine in step ①, in step 0, it is checked whether or not the interruption was caused by turning on the stop key.
If it is not interrupted, the number of copies set for one original in step ■ =
Check whether the number of copies is the same.

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 step is interrupted by turning on the stop key, 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 consists of subroutine 17.

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

FIG. 12 shows a main routine 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 0. In this initial setting, the input interface circuit 106 and output interface circuit 108 of the microcomputer 107 are cleared.

If the number of sheets stored in the bin is reached, the process goes to the final processing control routine of step @. This final processing control routine is subroutine 2.
Consists of 4.

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

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 35, and these subroutines will be explained next. .

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 O, it is determined whether or not the multi-job key 52 is ON, and if the multi-job key 52 is ON, then in step O, it is checked whether FG11=1. If the multi-job key 52 is not ON, FGII is turned OFF.
After that, return to the main routine (step [
phase]). Since it is a step, if FGI1=1, it also returns to the main routine.

If FGI 1 is not 1 in step O, change FGI 1 to 1.
After that, check whether FGI 2 = 1 or not.
If G12 is not 1, it is a multi-job seventh mode, so set FGI2 to 1 and proceed to steps [phase] to step @). In step ■, the number of items is displayed, the original number execution counter display 65 is turned OFF, the one copy number set counter display 49 is set to O, the one copy number execution counter display 50 is turned OFF, and the Harajuku number of copies key press display is displayed. vessel 59
Turn on a and 59b. Next, in step (2), a multi-job load signal is output to the sorter 3 and the process returns to the main routine.

If FGI2=1 in step (2), it is not the multi-job mode, so in step 0, FGI2 is set to 0, and then the process goes to step 0. Because of this step, the number display 5
4. Turn off the number counter display 55, the number of original sheets display 63, the number of original sheets set counter display 64, and the number of original sheets execution counter display 65, put 1 in the number of copies set counter display 49, and Sheet number execution counter display 50, original number key press display 59a, 59

) - Talcopi one sheet number indicator 70. And the document number mismatch display 69 is turned off.

Next, in step 0, an all-job end signal indicating that all jobs have been completed is output to the sorter 3, and CTJB
After inputting PT, CTJBTC, and CTJBPCJ, the program returns to the main routine (steps ~).

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 [stock], it is checked whether or not the number of original sheets key 56 is ON, and if it is ON, FG21 is pressed in step O.
=1. If the number of originals key 56 is not ON in step 2, Fe12 is set to O in step @ and the process returns to the main routine. Also, step [
phase], if FG21=1, the process returns to the main routine.

If FG21=1 is not found in step 0, Fe12 is set to 1 in step O, and F'GI2=1 is checked in step O. If FG12 is not 1, it is not the multi-job mode and the process returns to the main routine. FGI
If 2=1, it is the multi-job mode, so check whether the original number confirmation display 71 and the copy number confirmation display 72 are ON in step O.
, ON (If there is, at step 0 (CTJBPT) ≦
(:CTJBTC) Check. (CTJBP
T) is the number of jobs currently displayed, j5, (
CTJBTC) is the maximum input value. If the original number confirmation display 71 and copy number confirmation display 72 are ON, it is not possible to input more data than the currently input data, so only changes to the data of the already input job are accepted. [CTJBPT)≦(CT
JBTC), the process returns to the main routine.

If the confirmation display 71 for confirming the number of original sheets and the confirmation display 72 for the number of copies placed in step O are not ON, and if (CTJBPT)≦(CTJBTC) in step O, the number of original sheets discrepancy display will appear in step O. It is checked whether or not 69 is ON, and if it is ON, the process returns to the main routine. If the original number discrepancy display 69 is not ON, in step O, (CTJBPT) ((CTJBP
Check C). ["CTJBPC) is the number of executed jobs. Since there is no need to input data for executed jobs, (CTJBPT) ((CT
JBPC), the process returns to the main routine. (CTJBPT) (If not (CTJBPC), check (CTJBPT) = (CTJBPC) in step O. If (CTJBPT) = (CTJBPC), it is a job before execution, and the input of the number of originals set is not accepted. Attach.(CTJBPT),,-(CTJBP
If C), in step 0, it is checked whether the original number execution counter and the one copy number counter are O,
If it is not 0, the copy operation has already started and the process returns to the main routine. If the original number execution counter and one copy number execution counter are 0, it means that the copying operation has not yet started, so the number of originals set is received (-j).

Next, in step 0, it is checked whether the original number key 56 is ON or not, and if it is ON, FG22=1 is checked (Step 0). If FG22=1, the original number key 56 has already been pressed, so the process returns to the main routine. , Fe12; If it is not 1, after setting Fe12 to 1 and setting FG32 to 0, the number key 2 press indicator 62
is turned on, and the original number key press indicators 59a, 5 are turned on.
9b1 The number-of-one-copy key press indicators 60a, 60b and the input key press indicators 61a, 61b are turned off (steps O-0).

Next, subroutine 3 will be explained.

First, in step O, it is checked whether or not the number of copies key 57 is ON, and if it is ON, in step 0, Fe31
Check =1. If the number-of-copies key 57 is not ON, Fe21 is set to 0 in step O and then the process returns to the main routine.

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

If step 0 is not Fe31.1, step O is Fe2
After setting 1 to 1, go to step O. Next, steps 0 to 0 common to subroutine 2 are passed.

Since the original number key 56 is not ON in step 0, the process goes to step @. At step O, Fe32=1 is checked, and if Fe32=1 is not found, the process returns to the main routine. If Fe22=1, after setting Fe32 to 1 and setting Fe22 to 0 (step 0), the process goes to step (2).

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 turned on, Fe21 is set to O in step O, and then the process returns to the main routine. If Fe41=1, the process returns to the main routine.

If Fe41 is not 1 in step O, set Fe12 to 1 and check FGI 2=1 (step ■, @)
. If FGI2 is not 1, it is not the multi-job mode and the process returns to the main routine. If Fe12=1, F'G22=1 is checked, and if Fe22=1, the data on the numeric keypad 48 is entered into the document number set counter and displayed (step 0-0). Next step 0
Check that [copy number set counter] = 0,
[One copy number set counter] = 0, one copy
(Turn on the number key press indicators 60a and 60b and turn off the numeric key press indicator 62 (step @). Return to the main routine. If [copy count counter] is not 0, the input key press display will appear. 61a,
61b is turned on, and the numeric key press indicator 62 is turned on.
After changing to FF (Step Co., Ltd.), return to the main routine.

If Fe22 is not 1 in step O above, F in step ■
Check e32=1. If Fe32=1, the data from the numeric keypad 48 is entered into the copy number set counter and displayed, and the [original number set counter] value O is checked (step 0°0). [Original sheet number set counter] = O, the original sheet number key press indicator 59a, 59
b is turned ON and the numeric key press indicator 62 is turned OFF.
After that (step 0), the process returns to the main routine. If the step [original sheet number set counter] is not 0, the input key press indicators 61a and 61b are turned on,
Then, after turning off the numeric key press display 62, the process returns to the main routine (step).

If Fe32 is not 1 in the above step, check whether the setting confirmation key 66 is ON in step O, and
If not N, the process returns to the main routine. When the number confirmation key 66 is ON, the data on the numeric keypad 48 is
BPT, set Fe12 to 1, and then return to the main routine (step O).

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.

At step tf and step @, it is checked whether the input key 58 is turned ON or not, and if it is not turned ON, the process returns to the main routine. If the input key 58 is ON, check that Fe22=1, and if Fe22=1, check that [copy number setting force/counter]=0 (step 0.0)
. If Fe22 = 1, check for Fe32 = 1 in step O, and if Fe32 = 1, go to step O,
Moreover, if Fe32 is not 1, the process returns to the main routine.

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

If [copy sheet number set counter] = not 0 and [original sheet number set counter] = 0, (CTJ
The value of the copy number set counter and the value of the original number set counter are stored in the memory specified by BPT) and displayed (step 0).

Next, Fe22 and Fe32 are set to O, and the input key press indicators 61a and 61b, the numeric key press indicator 62, and the number-of-copies key press indicators 60a and 60b are turned off (step 0, O). Next, add Fe51 to 1. ! :t, then (CTJBPT)=Mtvfzy (step @, @). This M is the maximum number of items that can be input in multi-job mode. (CTJBPT), t(If [”C'r J I3 T C)
) (If it is not M, that is, if the maximum input value is larger than M, it is impossible to input job data, so the process returns to the main routine through subroutine 10 of step. e (:CTJ
BTC) (M) Since the job data is an input TJJ function, (CTJBTC) is set to +1 in step O, and then the process passes through subroutine 10 of step O and returns to the main routine.

If (CTJBPT) is not 2M in step @ above, there is still a job number area that can be input in the arrow, so after turning on the original number key press indicators 59a and 59b, (C
TJBPT)) (CTJBTC) is checked (step O). This is a check to see if the displayed job has been input. (CTJBPT))(
CTJBTC), the displayed job has not been entered yet, so change the value of CTJBPT to CTJ
The data is put in BTC, passed through the supply chain/7, and checked to see whether or not the original number confirmation display 71 or the copy number confirmation display 72 is ON (steps Q to @).

In the above step, if the number of original sheets confirmation display 71'' or the number of copies confirmation display 72 is not 01'J, job input is possible (CTJBPT) +1
Then, 0 is entered and displayed in the original number set counter, O is entered and displayed in the number of copies set counter, and the process returns to the main routine through subroutine 10 (
Step O~). Due to the above steps, the original number confirmation display 71 or the copy number confirmation display 72 is ON.
If so, it is impossible to input the job, and the process returns to the main routine through subroutine 10 of step (2).

Because of the above steps (CTJBPT)) (CTJBTC)
If not, the displayed job has already been input, and the process goes through subroutine 7 to the document number confirmation display 71-! Otherwise, it is checked whether the number of copies confirmed display 72 is ON (steps σ), 2). If the original number confirmation display 71 or copy number confirmation display 72 is ON in step 0, it is impossible to input the job, so the process returns to the main routine through subroutine 10 of step 0. .

If the original number confirmation display 71 or copy number confirmation display 72 is not ON in step 0 above, set (CTJBPT) + 1 in step [phase] and then specify with (CTJBPT) in step [phase]. After displaying the contents of the memory in the copy number set counter and the original number set counter, step 0 subroutine 1 is executed.
0 and return to the main routine.

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 FIG. 17 will be explained.

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

At step ■, check F(15/21, that is, check whether there is an input job or not.
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, Fe12;1 is checked (step [Yes],
[Yes]).

If Fe61=1, the process returns to the main routine.

If Fe2 t=t, then after setting Fe21 to 1 (C
Check TJBPT)) (CTJBTC) (step, pu, [phase]). (CTJBPT)) (CTJBT
The check in C) means checking whether the displayed job has been input. l”cTJBPT)
) (CTJBTC), 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 set (CTJBPT) to 1 (step [Yes]) . Next, in step ■, set Fe22 and Fe32 to 0, and then in step ■, (CTJB
PT) The contents of the memory specified by PT) are entered into the one-copy number set counter, the one-copy number execution counter, the courtesy number of copies set counter, and the original number execution counter and are displayed. Next, turn off the numeric key press display 62, input key press display 61a, 61b, and copy number key press display 60a160b in step ①, and then check that [original sheet number set counter] = 0 in step ②. .

[Original sheet number set counter] = 0, the original sheet number key press indicator, S? a.5? Turn b ON and step 0)
, and if [original sheet number set counter] = 0, the original sheet number key press indicator 5'la, 5? After turning OFF b (step ■), the process returns to the main routine.

In the above step, pu [phase] (CTJBPT)) (CTJBT
If it is not C), the displayed job has been input, so set (CTJBPT) + 1 in step [phase], and then set (CTJBPT) > [”CTJBTC] in step ■.
Check. If it is not [C or TJBPT)) (CTJBTC) at step ■, proceed to step ■; 1 step is 1, and at step ■, the contents of the memory specified by (CTJBPT) are set as the copy number set counter, the copy number execution counter, and the original. It is displayed in the sheet number set counter and the courtesy sheet number counter.

At step [phase] (CTJBPT)) (CTJBPC)
Then, Fe22 and Fe22 are set to O, the number of original sheets set counter is set to 0 and displayed, and the number of copies set counter is set to 0 and displayed (step [phase] to @l). Go to [phase].

If the number confirmation key 66 is not ON in the above step [phase], Fe21 is set to O and then Fe42=1 is checked (step 0, ■). If Fe42=1, it means that the numeric keypad 48 was turned on while the numeric confirmation key 66 was pressed, so set Fe42 to 0 and press (CTJBPT))(C
TJBTC) (Step 0, [Stocks])
. In this case, (CTJBPT) is the value inputted using the numeric keypad 48. At step ■ (CTJBPT)) (C
TJBTC), the displayed job is an uninput job, so the CTJBTCO value is changed to CTJB
PT (step@), i.e. [CTJBP
Set T) to the maximum input value and then step [phase]
In step 2, the contents of the memory specified by (CTJBPT) are entered into the copy number set counter, copy number execution counter, original number set counter, and original number execution counter and are displayed.Step [phase] So (C
If it is not TJBPT))(CTJBTC), the displayed job has already been entered, so through step @,
In step (2), the contents of the memory specified by l''cTJBPT) are entered into the copy number set counter, the copy number execution counter, the original copy number set counter, and the original copy number execution counter and are displayed.

Next, subroutine 7 shown in FIG. 1s18 will be explained.

This subroutine 7 is included in the standby routines of ST and B.
The total remaining value of the number of original sheets that are I is 7.

R, l, 1(,2, R3
is a working register.

In the square, step ■, put N in 几1. This N is the maximum value of the number of bins 3e of the sorter 3. Next, in step ■, R2
(CTJBTC), that is, set the value of R2 to be the maximum number of jobs that have been input.

In the next lζ step (■), it is checked that the courtesy number set value of the memory specified by [R2]=1. If the set value of the number of originals in the memory specified by [R2] is not 1, the sort mode is set to (R1) - ((几2) in step @.
Put the calculated value of the number of copies of the memory set value specified by 1 into R1, and go to step [phase] (R1) (check for 0).

If the above step sets the number of originals in the memory specified by (R2) and the value is 1, as a stack mode, step ■ sets the number of copies of the memory specified by (R1) - ((R2). value/P1] into R1, go to step @ (R1) and check for <0. Here, Pl is the maximum number of copy papers P that can be accommodated in one bin 3e of the sorter 3, In calculating the memory copy number set value/Pi specified by (R2), the value below the decimal point is rounded up.

In step ■, (R1) (If not 0, put the value of (R2) - 1 into 几2 and check (R2); Q (step @, [phase]). In step @, (R2) = If it is not 0, return to step ■. At step [Yes], (R1) (0
If so, since there is no set remaining amount value for the number of copies, the number of copies set confirmation display 72 is turned on (step @).

If (R2)=O in step 0, or after step [Yes], the value of R1 is put into CTCPzz (step ■). This CTCPZZ contains the set remaining amount value of one copy, that is, the remaining pin amount value of the sorter 3.

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

In step [Yes], put the value of CTJBTC into R2, and put Q into 几3 with Step and B. This Q is the maximum number of originals 0 that can be set on the original setting table 2a of the ADF 2. 1st step ■
In this step, enter the calculated value of (R3) - (original set sheet number code in the memory specified by (R2) (original set sheet number value in the memory specified by (R2)) into R3. Next step [
Yes], check (R3) < 00, (3) If it is not 0, enter the value of (R2) - 1 in R2, and then (R2)
Check =O (step [phase], [phase]). If (R2) is not 0 in step ■, return to step @.

In step [Yes], (R3) (If o, there is no remaining amount of original sheets set, so in step [Phase], turn on the document number confirmation display 71. In step 0, (R2) =
If it is 0, or after step [phase], the value of R3 is entered by CTORZZi (step 2) 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.

Without switching, it is checked in step [phase] whether the remaining amount confirmation key 67 is ON or not, and if it is ON, FGI2=1 is checked (step [phase]). If FG12 is not 1, there is no point in checking the remaining amount, so the process returns to the main routine. If FGI2=1, the content of CTORZZ is displayed on the original sheet count y set counter display 64, and
The content of CTCPZZ is displayed on the copy number set counter display 49 (step 2), and the process returns to the main routine.

If the remaining amount confirmation key 67 is not turned on in step (■), the raw material sheet number set counter display 64 displays the courtesy sheet number set value, and the copy sheet number set counter display 49 displays the number of copies (set) M. Then, return to the main routine.

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

This subroutine 9 is the standby routine lζ of step
Also, the job cancellation key 68 is accepted.

First, in step [phase], the job cancel key 68 is turned OFF.
Check whether it is N. If the job cancel key 68 is ON, FG91=1 is checked (step e). If the job cancel key 68 is not ON, FG91 is set to 0 (step [phase]) and the process returns to the main routine. If FG91=1 at step 0, the process returns to the main routine.

If FG91 is not 1 in step [phase], FG91 is set to 1, and then it is checked whether or not the document number mismatch display 69 is ON (step 2, [stock]).

If the original number mismatch display 69 is ON, after turning off the original number mismatch display 69, it is checked whether the values of the original number execution counter and the one copy number execution counter are 0, that is, the values are not displayed. Check whether the job being executed is before execution (steps ■), ■)).

If the original number execution counter and copy number execution counter are O in step ■, the displayed job has not yet been executed, so the main routine is executed through subroutine 7 of step ■ and subroutine 10 of step [phase]. Return to.

If the values of the original sheet count execution counter and the copy sheet count execution counter are not O in step [phase], the displayed job has been executed, so stop the execution of this job and move to step [phase]. CTJBPC)+1, then the saw A outputs a 1-job job signal indicating that job execution has ended.

Next, in step [F] (CTJBPC) ((CTJBT
Check C). (CTJBPC)<(CTJB
TC), it means that the number of executed jobs is greater than the maximum number of jobs entered. That is, since there are no remaining jobs, the program returns to the main routine 1 through subroutine 7 of step [Yes] and subroutine 10 of step [Yes].

In step 0, 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 [phase]), and display the original number set value and copy number set value in the memory specified in [CTJBPT) in the original number set counter and copy number set counter (step GIU). )
, the subroutine 7 of step (2) and the subroutine 10 of step [phase] are passed to return to the main routine.

If the number of originals discrepancy display 69 is not ON in step 0 above, (CTJBTC) ≥ (CTJB) in step [phase].
PT). At step [phase] (CTJB
If TC)≧(CTJBPT), the displayed job has not been input, and the process returns to the main routine.

At step [phase] (CTJBTC) ≧ (CTJBPT)
If so, the displayed job has been input, so check whether the values of the original sheet count execution counter and the copy single sheet count execution counter are O, that is, the displayed job has not yet been executed. Check whether it exists (step ■). If the values of the original sheet count execution counter and the copy sheet count execution counter are 0 in step [phase], the displayed job 2 has not yet been executed, so (CTJB
Erase the original number of copies set value and the number of copies set value of the memory specified by PT), and sequentially fill the contents of the next memory without leaving that memory blank (step [phase]
).

Next, in step [phase], (CTJBTC)=O is checked. If (CT, TBTC) is not 0 in step [Yes], it is set to (CTJBTC) -1 in step [phase], and if (CTJBTC) is 0 in step [phase], after setting FG51 to 0, , (C'TJBPT) is stored in the copy number set counter and the original number set counter (step ■).
). Next, the numeric key press indicator 62, the input key press indicator 61a161b, and the copy key press indicator 60a.
, 60b is turned off (step ■), and the [original sheet number set counter] is checked to be 0 (step ■). If the [original sheet number set counter] is O in step [phase], the original sheet key press indicator 59a, 5 is displayed in step ■.
9b is turned on, and if the [original sheet number set counter] is not 0 in step [phase], the original sheet number key press indicators 59a and 59b are turned off in step [phase], and then subroutine 7 of step G and step The program returns to the main routine through subroutine 10.

In step C above, (CTJBTC) ≧ (CTJBPT)
And if the values of the original sheet number set counter and the copy sheet number set counter are not 0 in step O,
Check (CTJBTC)≧(CTJBPC) using Step and Step ■.

If (CTJBTC) is not ≧ (CTJBPC) in step ■, it means that all the input jobs have been executed, so in step @ erase all the execution value of the number of courtesy sheets and the execution value of the number of copies per job in the memory related to the job, and step After outputting an all-job end signal to the sorter 3 indicating that execution of all input jobs has ended in step ■, subroutine 7 of step ■ and subroutine 1 of step ■
0 and return to the main routine.

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 @ is to eliminate the need for re-input when executing a multi-job with the same pattern.

In step ■ 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 Check the [Original sheet number set counter] = [Original sheet number execution counter] in ■.

In step O, 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.

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 ■, the process is being executed in step (■). To cancel the job, 1: Tode (CTJBPC) +1
After outputting the 1-job processing signal to the sorter 3 in Step 3, (CTJBTC), ((CT
JBPC). At step ■ (CTJB
TC) (If it is not (CTJBPC), some of the input jobs are not being executed, so go to step ■ and put the value of CTJBPC in CTJBPT, and in step ■ write the memory specified by (CTJBPT). The set value for the number of original sheets and the set value for the number of copies per sheet are displayed in the raw material sheet number set counter and the one copy sheet number set counter.In the above step [Yes], [”CTJBTC)((
CTJBPC), the input job is being executed, so the process returns to the main routine via subroutine 7 of step (2) and subroutine 10 of step (2).

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, step [stock] [CTJBTC]≧
Check (CTJBf'C).

If F()51 is not 1 in step ■, also [”C
If TJBTC)≧cCTJBPC) is not satisfied, that is, if all the input jobs have been executed, the total number of copies (one) is displayed in the number counter at step (2), and the process returns to the main routine.

In step ■, if (CTJBTC)≧(CTJB'PC), set 几2 to O, and set the value of CTJBTC to R1!
After inserting c ic (Rx) = (CT J B P
C) Make a tD f nick (steps ■～■)=
If (R1) = (CTJBPC) in step [Yes], the multiplication value of the original number set value and the copy number set value in the memory specified in (几1) is added to (R2) in step ■, In Step 2, enter the value of (R1) -1 into R1, and then return to Step 2. Steps ■ to ■ are repeated and when (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 determined in step ■. is added to (R2), and in step ■, the multiplication value of the actual number of originals and the actual number of copies in the memory specified by (R1) is (R2).
Subtract x from , and the left step ■ is the resulting value (
R2) is placed in the total copy number counter and displayed, 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, check FGI 2=1 in step, and
If G12=1, it is checked in step O whether or not 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 (2) whether or not the copying operation is interrupted, and if the copying operation is not interrupted, F G 111 is set to 1 (step, step (2)).

The determination as to whether or not the copying operation is interrupted is made, for example, by checking whether the number of copies set = the number of copies to be executed or by checking the stop flag; The reason why step ■ was provided is that - if there is a temporary interruption in copying the final courtesy,
The original introduction set detection means 24 of 6x is OFF, but this is because the print key 47 is not displayed in red at this time.

The copying operation is interrupted when the document O is left on the contact glass 7a and the number of copies to be executed has not reached the number of copies to be executed, and the copying operation is stopped.

In step ①, fTIll's document set detection means 24 is set to O.
If the copying operation is interrupted at step (2) and step (2), it is checked whether the pressure plate opening/closing detection means 30 is OFF (1) (step (2)). Pressure plate opening/closing detection means 30 is OF
If it is F, the step height F G 111 is set to 1,
In addition, the pressure plate opening/closing detection means °0""ON'C66&X
f y 7'■110""2°, (close and go to step ■).

Next, check FG51=1 with step and pu■, and
If 21=1 is not established, the FG112 is set to 1 in step (2).

If FG51=1 in step ■, then f y 7'
(ij□ te CCT J B T C) ≧(CT J
BPC). (CTJBTC)≧(CT
If it is not JBPC), the input job is being executed, so go to step ■Go to FG 112 in 1. ! - to do. If I'CTJBTC) ≧ (CTJBPC), there is a job that should be executed in the input job, so
Set FG 112 to 0 in step and step [phase]. If FG12 = 1 in step @ above, FG in step O
111 and FG 112 are set to 0.

Next, in step O, FG 111 = 1 is checked, and if FG ill = 1, in step θ, the print key 47 is displayed in red, meaning that copying is impossible, and the process returns to the main routine. Ste.

If FG111=1 in P, then FG in Pro.
Check 112 = 1. If FG112=1, the step goes to step [phase] and the bright key 47 is displayed in red. If F G 112 = 1, the print key 47 is displayed in green, meaning that copying is possible, in step @, 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 selects the sort mode or stack mode based on the set value of the number of originals in the multi-job mode.

First, check FG12 = 1 with ST, B■, and FG
If 12=1, it is not the multi-job mode and the process returns to the main routine. , FG12=1, the [original sheet number set counter] is checked at step @=1. [Original sheet number set counter) = 1, reset the sort mode and set the toshi (that is, F G 131 to 0)
) and set the stack mode, i.e. F G
132 is set to 1), then the sorter 3# mode signal is output (steps [stock] to O), and the process returns to the main routine.

, If [original sheet number set counter] is not equal to 1 in zf block ■, check that [original sheet number set counter] > 1 in step [stock]. [Original sheet number set counter] If it is 1, the stack shade should be reset, that is, F G
132 to O), set the sort mode (F < set counter) > 1,
Since the input value for the number of originals is 0, the sort mode and stack mode are reset and the sorter 3# mode signal is output (step O, @).

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, in step O, it is checked whether the print key 47 is ON, and if the print key 47 is ON, in step 2, it is checked whether the print key 47 is displayed in red. At step O, the button 11 and -47 are turned on.
If not, 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 O, that is, it is displayed in green, FGxz=t is checked in step O. If FG12=1, it is checked in step O whether the copy operation is interrupted. If the copy operation is interrupted, the copy start flag FG 141 is set to 1, the pre-y) ON (signal is output to the ADF 2), and then the main routine returns 11 turns. At step 0. If the copy operation is not interrupted, the copy start flag FG 141 is not set to 1 and a print ON signal is output to the ADF 2 in step (2). If FGI 2 is not 1 at the entrance of the above step, it is not the multi-job mode, so the copy start flag FG141 is set to 1 and a print ON signal is output to the ADF 2 (step 2, [stock]).

“If the copy operation is not interrupted at the step entrance, step 1
The print ON signal is output to the ADF 2 using the knob 1.As will be described later, this signal turns on AI-) and F2 to print the original mO or partition lI! Ld is conveyed, and only when it is determined that the document being conveyed is document 0, a copy start signal is output to the electronic copying machine l and the copy start flag FG141 is set to 1, and when the partition sheet d is Does not output copy start signal.

If the copying operation is interrupted in step (3) above, the print key 47
As soon as FG1 is turned ON, the copy start flag FG1 is activated.
41 is set as 1.

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

This subroutine 14 is a standby routine for steps and steps.
This is included and processes the copy start signal from the ADF 2 or the signal from the partition paper detection means 25.

Check FGI 2 = 1 at the square and step entrance, and if FG12 = 1, check the be start flag FG 141 = 1 at step [phase].

If the copy start flag FG141 is not 1, check the presence or absence of a partition paper detection signal at the step opening.

If there is a partition paper detection signal in step or step ■, the buzzer 109 will sound.
is turned on, and after resetting the partition paper detection signal, the [manuscript sheet number set counter] and [original sheet number execution counter] are checked (steps ① to ＠). If [original sheet number set counter] = [original sheet number execution counter] in step ■, the number of original sheet discrepancy indicator 69 is turned ON in step [stock], and the copy start flag FG is set in step [stock].
After setting 141 to 0, the process returns to the main routine.

The reason why the number of originals discrepancy display 69 is turned ON in step 2 after going through steps 1) If you accidentally set a smaller number of originals 0 than the entered number of originals in ADF 2, (2
) If you set the same number of original pages as the input number of originals into ADF2, but if you stack multiple originals and send them at the same time, that is, if you double feed the originals, and (3) Originals set in ADF2. This is a case where the number of original sheets is erroneously input larger than the number of original sheets.

If the copy start flag is 1 in the above step (2), or if there is no partition paper detection signal in step [Yes], the presence or absence of the copy start signal from the ADF 2 is checked in step [Phase]. When there is a copy start signal from ADF2 in step ■, [original sheet number set counter] =
Check [Original number execution counter], and if [Original number set counter] = [Original number execution counter], reset the copy start signal from ADF 2. Go there and turn on the original secret number discrepancy display 69. In such a case, the reason why the number of originals mismatch indicator 69 turns ON is (4) if you mistakenly set more originals than the number of inputted originals in the DF2, and (5) if the ADF2 is set to This is a case where you have mistakenly entered a smaller number of originals than the number of originals specified.

If FG12 is not 1 in the above step (2), the presence or absence of the copy start signal from the ADF 2 is checked in step O. If there is a copy start signal from ADF 2 in step [phase], or if [original sheet number set counter] = [original sheet number execution counter] in step @, the copy start flag F G 14'l is set in step e.
is set to 1 and returns to the main routine. Step O
If there is no copy start signal from ADF2, the process returns to the main routine.

If there is no copy start signal from the ADF 2 in step (2) above, a check of FG 151 = 1 is performed in step @. If FG151 is not 1, it is checked in step 2 whether or not the original is the last sheet. Step, bu ■ F
If G 151 = 1, and if the document is not the last sheet in step [Yes], the process returns to the main routine.

Next, in step (2), if the original is the last sheet, in step O, a check mark is set to 1 to see if it is the [manuscript sheet number set counter]; [original sheet number execution counter]. At the step entrance, if [original sheet number set counter] = [courtesy sheet number execution counter], go to step [stock] and turn on the original sheet number discrepancy display 69. The reasons for turning on the document number mismatch indicator 69 in such a case are the above (1) to (3).
This is shown in .

In step ■ or O above [Original sheet number set counter]
; If it is [original sheet number execution counter], check FG 151 = 1 in step ①. F G
If 151 = 1, then set FG 151 to 1,
(CTJBPC)+1, and after outputting 1 job end signal to sorter 3, (CTJBTC)≧(CTJB
Check the PC) (steps ■～■). If F G 151=1 in the above step O, the process goes to the step entrance.

If (CTJBTC)≧(CTJBPC) in step ■, some of the input jobs have not been executed, so after putting the value of CTJBPC into CTJBPT in step ■, enter (CTJBPT) in step [phase]. The set value for the number of original sheets and the set value for the number of copies in the memory specified by are input to and displayed on the original sheet count set counter and the one copy sheet number set counter, and then the process returns to the main routine. At the step mouth (CTJBTC) ≧ [CTJB
If it is not a PC), the input job is being executed, and the process returns to the main routine.

Next, subroutine 15 shown in FIG. 26 will be explained.

This subroutine 15 is included in the standby routine of step ①, and turns ON the f-109 after a certain period of time.
Make it F.

``First, in step [YES], check whether the buzzer 109 is ON or not. When the buzzer 109 is ON, step 1 checks that FG 161 = 1. At first, FG161 is not 1, so set FG161 to 1 in step ■, and turn off the buzzer OF in step [Yes].
After setting the value of the F counter to O, the process returns to the main routine. If the buzzer 109 is not ON in step [phase], the value of the buzzer OFF counter is set to O in step [phase] and the process returns to the main routine.

If F G 161 = 1 in step ■, the [buzzer OFF counter] is set to +1 at the step entrance, and the [buzzer OFF counter) Tnz is checked at the tip [phase]. This TBz is the time during which the buzzer 109 is ON in step O. If step [Yes] (buzzer OFF counter)) is not Tnz, return to the main routine. While the buzzer 109 is ON, a timing pulse is input to the buzzer OFF counter at predetermined time intervals in step ○, and when it is determined in step O that it is [buzzer OFF counter)) Tnz, the buzzer 109 is turned OFF. After setting FG 161 to 0 (

Next, the subroutine 21 shown in FIG. m32 will be explained.

This subroutine 21 is included in the document feed control routine of steps ①, ②, ②, and 0, and outputs a partition paper detection signal and a copy start signal to the electronic copying machine 1.

First, check that (TPO)≧normal at step [Yes]. This TPO is a timing pulse counter that counts the number of pulses output from the encoder 19. B above, when feeding the partition paper d with the ADF 2, the predetermined period from the start of feeding until the partition paper detection means 25 detects the first hole dr of the partition paper d and the next hole dx is The number of pulses output by the encoder 19 up to this point,
Ru.

If [“TPO]≧K” is not found in step [Yes], it is checked in step [Yes] whether the partition paper detection means 25 is ON.This partition paper detection means 25 detects the partition paper d
- It turns ON no matter how many originals O are detected. When the partition paper detecting means 25 is turned on in step [Yes], the AFG 21 is set to 1 in steps [O] 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 AFG21=1 in step (2), the partition paper detection means 25 has detected the hole d1 in the partition paper d, so in step (2) AFG22 is set to 1 and the process returns to the main routine. This AFG22 is for partition ff d hole d
This is a flag for detecting l. AFG21 in step ■
If not =1, the partition paper detection means 25 has not detected the partition paper d or the original O, and the process returns to the main routine.

Next, if (TPO)≧R in step ■, step e
De (TPC) = make a simple cheek.

(TPC)=R = 6, sf 7'■-('
Check A F G22=1. This step O
If A F' G 22 = 1, it means that the ADF 2 is feeding the partition paper d, so in step ■, a partition paper detection signal is output to the electronic copy aX, and in step [
Set AFG21 and AFG22 to 0 and return to the main routine.

If AFG22 = 1 in step ■, A in step ■
Check FG21 =1. AFG at step mouth
If 21=1, it means that ADF 2 is feeding document 0, so step 1.

Output a copy start signal and a document count signal to the electronic copying machine 1 at step ①, and proceed to step [stock].

If AFG21 is not 1 in step (2), the second paper feed detection means 27 is set to 0.0 in step (2). Check whether it is N or not. If the second paper feed detection means 27 is not ON in step e, the ADF jam flag is set to 1 in step 2, and the process goes to step O, because the partition paper d or document 0 is jammed. In step ■, the second paper feed detection means 27 is set to O.
If N, 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 sorting operation control routine of step @, 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 (2), it is checked whether the copy ejection sensor 37 is ON. Copy ejection sensor 37 is O
If N, check 5FGI l=1 in step O. This 8FG11 turns ON the copy ejection sensor 37.
This is a flag to detect. 8FGx with step [Yes]
If 1 is not 1, 5FGI is set to 1, and electronic copying machine 1
Copy eject 9″1i″′″L′″((,X,-r・7
°0・■))t4yyv-.

Return to Chin. Copy ejection sensor in step O above? -37 is not ON, 8FGl in step [phase]
After setting 1 to O, return to the main routine. If 5FGI l=1 at step [stock], return 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 O, and controls the job partition display 39 based on the 1-job job signal from the electronic copying machine 1.

First, in step O, 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 0 is turned ON, and then the process returns to the main routine. If there is no 1 job end signal at the step port,
Return to 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.

At step O, the presence or absence of an all-job end signal is checked, and when the all-job end signal is present, at step @, it is checked whether the bin copy paper sensor 38 is ON. If the bin copy paper sensor 38 is not ON, all job partition indicators 39 are turned OFF in step ①.
to 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.

Even if the multi-job fade is canceled, do not immediately turn off the job partition display 39. Remove the copy paper P from all pins 3C of the sorter 3, then turn off the job partition display 39 and copy. The job separation for paper P is made clear.

If there is no all-job end signal in the above step [phase], the copy paper sensor 38
is OFF, the process returns to the main routine.

In the illustrated embodiment, one sorter 3 is connected to the electronic copying machine 1, 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 pins of the sorter, may be changed.

Effects According to the present invention, it is possible to successively copy a group of originals with different copying conditions, and to calculate and display the remaining amount of originals that can be set in the automatic document feeder. can.
