Abstract

PURPOSE:To display an accurate number of copied sheets even though the jammed paper sheets are deleted, by counting the number of discharged sheets. CONSTITUTION:A desired number of copy sheets set with a ten-key 12 is displayed at a copy sheet setting/display device 50. With push of a copy button 43, the number of copies is counted up with each feed of a copy sheet. Thus the copying is successively carried out, and the number of copied sheets is displayed at a display 51. At the same time, the actuating frequencies of a microswitch at a paper discharging part are counted and stored. When a jam occurs, the number of discharged sheets is displayed at the display 51. At the same time, the working of a copying machine is stopped. After the jammed paper is deleted, the copying is carried out continuously until the copied sheets reach a set number while counting up the copied sheets after the displayed number of discharged sheets. Even in case an interrupted copy is carried out with an interruption key 42, the number of copied sheets is replaced with the number of discharged sheets when a jam occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous copy table mode that continuously copies a plurality of sheets from the same original according to a predetermined setting operation, and an interrupt copy mode that performs interrupt copying in the middle of the continuous copy mode operation. The present invention relates to a method for counting the number of copies of a copying machine capable of operating in various modes.

In the conventional copying machine mentioned above, the number of sheets of copy paper fed during the copying process is counted, and when the number of sheets fed reaches a preset number of copies, paper feeding is stopped and the desired number of copies is made. I have a copy. Therefore, in each of the above aspects, when a paper jam occurs in the copy paper transport path before a series of copying operations are completed, the previous copying work is interrupted and the paper jammed and the copy paper being transported are removed from the copying machine. When they are taken out, the number of copies taken out has already been counted. Therefore, if the copying operation is restarted in this state, only the number of copies will be obtained by subtracting the number of collected copies from the set number of copies.

In addition, even if a copy paper jam occurs when the above-mentioned operation switching operation is performed, i The number of copies that can be obtained is the same as the number of copies removed from the paper that caused the paper jam.For this reason, in the past, the number of copies was set when restarting the copying operation after clearing the paper jam. I had to start over.

The present invention solves the above-mentioned technical problem, and the number of copies made by a copying machine is such that a desired number of copies can be obtained by continuously restarting the previous copy without resetting the number of copies after a paper jam is cleared. The purpose is to provide a counting method.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

, each key 12, 41° 42.43 and the print button 13, the display 50.51
is driven to turn on via the driving means 60.

FIG. 5 is a flowchart for explaining the operation of the control system shown in FIG. Control means 381-t.

(5) Continuous copying mode in which multiple copies of the same original are made consecutively according to predetermined settings, and the cause of the continuous copying mode is C: Interrupt copying is performed in the middle of the operation of the continuous copying mode.
In controlling the operation of each mode with the B1 interrupt copy mode,
When a paper jam occurs in the copy paper 8, the display 50.
The following operations are performed in connection with 51.

When the power switch 11 is pressed in the continuous copying mode step St, the control means 38 is turned on and becomes operable. In step S2, a signal representing the preset number n1 of copies to be made, which is input to the control means 38 by the numeric keypad 12, is stored in the first memory M1 of the control means 38 in step S3. The control means 381d displays the set number n1 stored in the first memory M1 in step S3 on the display 50 via the driving means 60 in step S4.

Here, if the clear key 43 is pressed in step S5 to correct the set number of sheets n1, the contents stored in the first memory M1 are erased and the operations from step S1 are repeated again. When the print button 13 is pressed in step S6, the control means 38 starts the copying operation of this electrostatic copying machine, and thereby
is moved back and forth. The detection switch 35 supplies a high-level pulse signal to the control means 38 every time the document table 2 moves back and forth, that is, for each number of copies of the document 3. The control means 38 counts this high-level pulse signal using the register R1 in step S7, and stores the counted value, ie, the number of copies m1, in the second memory M2 in step S8. In step S9, the control means 38 sets the stored contents of the second memory M2, that is, the number of copies ml to 1! is displayed on the display 51 via the auxiliary means 60. In this way, on the display 51, the number m1 of copies is sequentially displayed for each reciprocating movement of the document table 2, that is, for each copying operation of the copying machine.

In the next step S10, it is determined whether a paper jam of the copy paper 8 has occurred or not based on a signal from the paper jam detection circuit 33. When the paper jam of the copy paper 8 has not occurred, in the next step Sll, the contents stored in the 17th memory M1, ie, the set number of sheets n1, and the contents stored in the second memory M2, ie, the number of copies m1 are compared. Stored contents of the first memory M1, that is, the set number of sheets 01
and the contents of the second memory M2, that is, the number of copies m1
(nl)ml), the next operation of the stethoscope S12 is performed.

When the copying machine performs a copying operation, copy paper 8 is placed on the tray 10.
is ejected. The detection switch 36 sends a high-level pulse signal to the control means 38 every time the copy paper 8 is ejected.
given to. In step S12, the control means 38 counts this high-level pulse signal using the 4 to 2 register R2, and in step 513 stores the counted value, ie, the number m2 of discharged sheets, in the third memory M3.

In step 514, it is determined whether or not the interrupt key 42 has been pressed. When the interrupt key 42 is not pressed, the operations from step S7 are repeated.

In step SIO, when the occurrence of a paper jam in the copy paper 8 is detected, all copying operations of the copying machine are stopped in step s15. Here, the entire copying operation of the copying machine refers to the operation of the document table 2, the photosensitive drum 22, the paper feed roller 25 for conveying the copy paper 8, and other rollers.

In the next step 516, the contents of the third memo 9M3, that is, the number m2 of ejected sheets, are stored in the second memory M2. At this time, the number m1ti of double filial sheets stored in advance in the %2 memory M2 is deleted.

In step 817, the content stored in the second memory M2, that is, the number m2 of discharged sheets, is displayed on the display 51 via the driving means 6o.

When the jammed copy paper 8 is removed from the machine body 1 and the reset switch 39 is suppressed in step 818, the stoppage of all copying operations of the copying machine in step 515 is released, and the copying machine is restarted. 41 copies can be made. In step S19, at the same time as the reset switch 39 is pressed in step 518,
The contents stored in the second memory M2, that is, the number m2 of ejected sheets, is stored in the second register RIK. After that, when the print button 13 is pressed, the operation (from step s6) is repeated again, and in step 57, the counting operation starts again from the number m2 of discharged sheets in the second register R2, and the number of sheets M'1 is increased. Number of remaining copies to be made at the time of occurrence (
nl-m2) is copied.

In step Sll, the stored contents of the first memory, that is, the set number of sheets n,,'jll, and the second memo IJM
When the stored contents of No. 2, that is, the number of copies m1, become equal, the copying operation of the copying machine is stopped in step S20. Here, in the copying operation of the copying machine, the operation of the original table 2, the photosensitive drum 22, the paper feed roller 25 for conveying the copy paper 8, etc. is different from the entire copying operation described above. It does not include a roller for discharging the copied copy paper from the machine 1 such as the machine 1. In step 521, the number of copy sheets 8 discharged from the machine 1 after the copying operation was stopped as described above is counted by the second register R2. Step S2
2, the count value counted by the second register R2 in step S21, ie, the number of discharged sheets m2, is stored in the third memory M3. In step S23, the contents stored in the second memory M2, ie, the number of copies m1, and the contents stored in the third memory M3, ie, the number m2 of discharged sheets, are compared, and when the number of copies m1 and the number of discharged sheets m2 are equal, K is In the next step 5-24, all copying operations of the copying machine are stopped. Note that in step S23, the stored content of the second memory M2, that is, the number of copies ml, and the stored content of the third memory M3, that is, the number of ejected sheets m2 are different (m
l)m2) When the copying operation is stopped in step 520, K assumes that the copy paper 8 that has not been ejected from the machine 1 is the number of paper jams minus one, and the operations of steps 515 to 519 described above are performed. will be carried out. In this manner, in steps S1 to S24, the control means 38 controls the continuous copy mode operation.

As mentioned above, when a paper jam occurs in the copy paper 8 in (3) continuous copying mode, the number of copies ml counted by the second register R2 according to one copying operation of the copying machine
is the number of ejected sheets m2 counted by the second register R2
The data is changed to $2 and stored in the $2 memory M2. Therefore, even if a paper jam occurs in the copy paper 8 and the copy paper that caused the paper jam is removed from the machine body 1, the number of copies that caused the paper jam is not included in the number of copies m1.

Therefore, when the copying operation is restarted after the paper jam is cleared, K is the preset number of sheets n1 determined by the numeric keypad 12.
You can only get copy paper.

Further, even if a paper jam occurs, there is no need to reset the set number of sheets n1°.

(6) Interrupt copying mode When the interrupt key 42 is depressed in order to perform interrupt copying during the operations described in steps 81 to S24, that is, during the continuous copying mode, as described above, step S14 is performed. That will be determined. When the interrupt key 42 is pressed, the copying operation of the copying machine is stopped in step S25, and the display 46 is lit as described above to indicate that interrupt copying is to be performed. At this time, in the next step 526, the stored contents of the first memory M1 to third memory M3 are stored to the fourth memory M4 to sixth memory M6, respectively. That is, the fourth memory M4 stores the set number of sheets n1, the fifth memory M5Kti stores the number of copies m1, and the sixth memory M6 stores the number of discharged sheets m2.

When the #-i interrupt key 42 is pressed in step S27, it is determined based on the signal from the paper jam detection circuit 33 whether or not a paper jam of the copy paper 8 has occurred. At this time, when a paper jam of the copy paper 8 is detected, the display 46 is turned off in step 828, and all copying operations of the copying machine are stopped. Further, in the next step S29, the stored contents of the fourth memory M4 to the sixth memory M6 are the first. Memory M1 to third memory M3
Stored in That is, the first memory MIK stores the set number of sheets n1, the second memory M2 stores the number of copies m1, and the third memory M3 stores the number of discharged sheets m2. At this time, the stored contents of the first memory M1, that is, the set number of sheets n1, are stored in the drive means 60 in step S30.
is displayed on the display 50 via. In step 831, the contents stored in the third memory M3, ie, the number m2 of ejected sheets, are stored in the second memory M2. The contents stored in the second memory M2, that is, the number m2 of ejected sheets, are transferred through the driving means 60 in step S32. : is displayed on the display 51.

When the jammed copy paper 8 is removed from the machine body 1 and the reset switch 39 is pressed in step 533, the stoppage of all copying operations of the copying machine in step 828 is canceled and the copying machine resumes copying operation. It becomes possible. In step S34, at the same time that the reset switch 39 is pressed in step S33, the second
The stored content of the memory M2, ie, the number m2 of discharged sheets, is stored in the first register RIK. If the interrupt key 42 is not pressed again in step s35 and the 1 print button 13 is pressed, the operations from step S6 described above are repeated, and in step S7, the second register R2 is set to the number of discharged sheets. The counting operation starts again from m2, and the remaining number of copies to be made (nl-m2) when the interrupt key 42 is pressed in step 514 and a paper jam occurs in step S27.
is copied.

In this way, in steps 827 to 835, when the interrupt key 42 is pressed and a jam occurs in the copy paper 8, the interrupt copying is suppressed, and the state before the interrupt copying, that is, the continuous copying mode is restored. state.

When the interrupt key 42 is pressed again in step S35, the same operation as in step S26 described above is performed in the next step S36, and the interrupt copy mode operation becomes possible. The subsequent operation of the control means 38 is the same as the operation from step S37, which will be described later.

If the occurrence of a paper jam is not detected in step 527, interrupt copying may be performed;
The control means 38 can operate from the next step S37. In step S37, a signal representing the set number of copies n'1 for interrupt copying, which is input to the control means 38 through the numeric keypad 12, is stored in the first memory M1 in step 538. At this time $ Lujista R
The stored contents of the first and second registers R2 are erased.

The control means 38 displays the set number n'1 stored in the first memory M1 in step S39 on the display 50 via the display means 60 in step S39. Here, if the clear key 43 is pressed in step 540 to correct the set number n'l, the set number n' stored in the first memory is cleared by 1, and the process starts again from step S37. The action is repeated.

Furthermore, when the interrupt key 42 is pressed again to cancel interrupt copying, the
It is determined in step S41, and in step S42, the stored contents of the fourth memory M4, that is, the set number n1, are stored in the first memory MIK, the stored contents of the fifth memory M5, that is, the number of copies ml, are stored in the 41!2 memory M2, and The stored contents of the 67 memory M6, ie, the number m2 of ejected sheets, are stored in the third memory M3. At this time, the set number n1 stored in the first memory M1 is
The number of copies m1 displayed on the display 50 in step S43 and stored in the second memory M2 is displayed on the display 51 in step S44. Also, in step 545, the second method of storing contents, that is, the number of copies m1, is stored in the second register RIK, and '! The contents stored in the lf3 memory, ie, the number m2 of ejected sheets, are stored in the second register R2. The subsequent operation of the control means 38 is similar to the operation from step S6 described above.

In step S41, if the interrupt key 42 is not pressed and therefore the print button 13 is pressed in step S46 without canceling the interrupt copying, the same operation as steps 87 to S9 in the continuous copying mode is performed and the next step is This is carried out in steps 847-S49.

That is, the number of copies i1 in interrupt copying is counted by the register R1, the counted value rr/1 is stored in the second memory M2, and the content stored in the second memory M2, that is, the number of copies rr/l is displayed on the display 51. do.

In the next step S50, it is determined based on the signal from the paper jam detection circuit 33 whether or not a paper jam has occurred in the copy paper 8 during the operation of the interrupt copying mode. When there is no paper jam in the copy paper 8, lj':
'11, in the next step S51, the stored content of the first memory M1, that is, the set number of copies n'1 for interrupt copying, and the stored content of the second memory M2, that is, the number of copies n(l,: for interrupt copying) are compared. .

When the set number of copies n' 1 and the number of copies d1 are not equal (
n'1)rr/1), steps 512 to 51 described above are performed.
3 and the next steps, l's'52~S53
It will be held in That is, the number of discharged sheets Go2 in the interrupt copying is counted by the second register R2, and the counted value, that is, the number of discharged sheets IT/2, is stored in the third memory M3.

In step S54, it is determined whether or not the interrupt key 42 has been pressed in order to cancel the forced copying. When the interrupt key 42 is not pressed, the operations from step S47 are repeated.

When it is determined in step S50 that a paper jam occurs in the copy paper 8, the same operations as in steps 515 to 519 described above are performed in steps 555 to 859. That is, all copying operations of the copying machine are stopped, the contents stored in the third memo IJM3, that is, the number of discharged sheets rr/2, are stored in the second memo M2, and the contents stored in the second memory M2, that is, the number of discharged sheets rr/2 are stored in the second memory M2. /2 is displayed on the display 51 via the drive means 60. When the copy paper 8 that has caused a paper jam is removed from the machine 1 and the reset switch 39 is pressed, the entire copying machine is reset in step S55. The stoppage of the copying operation is released, the copying machine becomes ready for copying operation, and the stored contents of the second memory M2, that is, the number of ejected sheets rr
/2 is stored in the register R1. After this, when the print button 13 is pressed, the above-mentioned step S46 is executed.
The operations from 1 to 1 are repeated again, and the remaining number of copies (n' 1 - rr/2) when a paper jam occurs in the interrupt copying mode is copied.

In step S51, when the stored content of the first memory, that is, the set number of copies n'1 for interrupt copying, and the stored content of the second memory M2, that is, the number of copied copies rd1 for interrupt copying, become equal, the above-mentioned steps S20 to The same operation as S24 is performed in steps S6:0-S.
64.

That is, the copying operation of the copying machine is stopped, and the number of copy sheets 8 discharged from the machine body 1 after the copying operation of the copying machine is stopped is counted by the second register R2, and the second register R2 is counted by the second register R2.
The count value of the register R, ie, the number of discharged sheets d2, is stored in the third memory M3.

Also, the stored contents of the second memory M2, that is, the number of copies ml
and the contents stored in the third memory M3, that is, the number of ejected sheets IT
/2 is compared, and when the number of copies 1 is equal to the number of discharged sheets rr/2, all copying operations of the copying machine are stopped.

When the interrupt key 42 is pressed in the next step S65 to cancel interrupt copying, the process returns to step S6 and the remaining number of copies to be made (( nl-m2
) to copy 9.

Note that in step 363, the contents stored in the second memory M2, that is, the number of copies i1, and the store contents in the @3 memory M3,
A content, that is, the number of ejected sheets rr/2 is different (rdl)
rr/2), it is assumed that a paper jam has occurred in the copy paper 8, and the operations of steps 855 to S59 described above are performed.

Further, in step S65, when the number of copies for interrupt copying is set again using the numeric keypad 12 without pressing the interrupt key 42 and therefore without canceling interrupt copying, K is set from step S37 described above. It is possible to perform the operation again.

In step 551, before the stored contents of the first memory M1, that is, the set number of interrupt copies n1, and the stored contents of the second memory M2, that is, the interrupt copy sheet loss rr/2, become equal, the interrupt key 42 is pressed and an interrupt is generated. When the copy mode is canceled, this is detected in step 54 as described above. When the interrupt key 42 is pressed in this manner, the display 46 is turned off as described above to display that the interrupt copying has been canceled, and in step S66, the first memory M1 to the third memory M1 to the third memory M1 to M3 are processed. : Store contents of 13 @7 memory M7~
The data are respectively stored in the ninth memory M9. That is, the seventh
The set number of sheets n'1 is stored in the memory M7, the number of copies ff/1 is stored in the eighth memory M8, and the number of discharged sheets rr/2 is stored in the ninth memo IJM9. Furthermore, in the next step S67, the fourth memory M4
~The stored contents of the sixth memory M6 are the same as those of the first memory M1~the third memory M6.
Each is stored in memory M3. That is, the set number n1 is stored in the first memory M1, and the set number n1 is stored in the second memory M2.
The VCFi copy number ml is stored, and the third memory M3 stores the discharged paper number m2. At this time, the content stored in the first memory, that is, the set sheet [nl] is displayed on the display 50 via the driving means 60 in step 568.

Also, the stored contents of $2 memory M2, that is, the number of copies (ml)
The butterfly is displayed on the display 51 via the driving means 60 in step S69.

If the copy paper 8 is jammed when the interrupt key 42 is pressed in step S54, this is detected in step S570. In this way, when the occurrence of a paper jam in the copy paper 8 is detected in step 570, all copying operations of the copying machine are stopped in step S71, and in step S72, the stored contents of the seventh memory M7 to %9 memory M9 are , 1st
The data is stored in the memory M1 to the third memory M3. That is, (@1 The set number of sheets n'l is stored in the memory M1, the number of copies 1 is stored in the second memory M2, and the number of ejected sheets IT/2 is stored in the third memory M3. When the stored contents of the first memory M1, that is, the set number of sheets n'l
is displayed on the display 50 via the driving means 60 in step S73.

In addition, the content stored in the second memory M2, that is, the number of copies rr
/1 is displayed on the display 51 via the driving means 60 in step S74.

When the jammed copy paper 8 is removed from the machine body 1 and the reset switch 39 is suppressed in the next step S75, the stoppage of all copying operations of the copying machine in step 571 is released. The copying machine becomes capable of copying operations. The subsequent operations of the control means 38 are those from step S46 described above. That is, when the interrupt key 42 is pressed and the interrupt key copy is canceled before the interrupt copy is completed, or when a paper jam occurs, switching from the interrupt copy mode to the continuous copy mode is suppressed. Therefore, when the print button 13 is subsequently pressed, the operation from step zs 47 described above is performed, and the operation for copying the remaining number of copies (n'l-rrf2) in the interrupt copying is performed.

If the occurrence of a paper jam is not detected in step S70, the control means 38 can perform the previous work from step S6, and the remaining number of sheets to be copied (nl-
m2) can be copied.

As described above, when a paper jam occurs in the copy paper 8 in @interrupt copying mode, copy sheets 1t(rr
/1 is changed to the number of discharged sheets d2 counted by the second register R2 and stored in the second memory M2. Therefore, if a paper jam of 80 copies occurs and the copy paper that caused the paper jam is removed from the machine body 1, the number of copies that caused the paper jam is not included in the number of copies rr/IK.

Therefore, similarly to (5) continuous copying mode, when the copying operation is restarted after the paper jam is cleared, it is possible to obtain the set number of copies n' 1 predetermined using the numeric keypad 12. Also, even if a paper jam occurs, the set number of sheets n' 1
There is no need to reset the settings. Also from the prisoner continuous copy mode)
(2) When a switching operation is performed from the interrupt copying mode to the continuous copying mode in the middle of each mode operation, and if a paper jam occurs in the copy paper 8, the mode of each mode operation is changed. Switching, # production is suppressed and the second copy mode in the copy mode before the switching operation is performed.
The number of copies m 1 counted by register R1,
rd1 is the number m2 of discharged sheets counted by the second register R2. rt? 2 and stored in the second memory M2. Therefore, when the switching operation of each mode operation is performed, copying is possible. Even when the paper 8 is jammed or jammed, only the preset number of copies n'l and n'2 are copied using the numeric keypad 12 in each mode. You can get a copy of the paper. Further, there is no need to reset the set number of prints nl and n'l.

As described above, according to the present invention, there are two modes: a continuous copying mode in which multiple copies of the same original are made in succession according to a predetermined setting operation, and an interrupt copying mode in which interrupt copying is performed in the middle of the operation of the continuous copying mode. Even if a paper jam occurs during operation, there is no need to reset the number of copies after the paper jam is cleared, as in the past, and the set number of copies can be obtained by continuing copying. . Furthermore, even if a paper jam occurs when switching between the copying modes described above, there is no need to reset the number of copies for each copying mode, and by continuing to copy, the set number of copies can be achieved. Copy paper can be obtained more reliably. Further, due to the effects described above, the copying machine according to the present invention can exhibit excellent operability.
