この発明は割込み機能を有する電子複写機の割込み複写
制御方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interrupt copying control method for an electronic copying machine having an interrupt function.
従来割込み機能を有する電子複写機では、複写中に割込

複写サイクルが終了する所謂サイクルアウトするまでの
間に例えば紙詰りなどが生じても、割込み要求が受は入
れられて割込み状態となり、上記不具合が先きの複写時
の不具合か、割込み時の不具合か判断しかね、混乱を招
ねくと共に、紙詰りとなった用紙が機密保持を必要とす
る場合、機密が守り難いなどの不具合があった。Conventionally, with electronic copying machines that have an interrupt function, when an interrupt switch is pressed to perform interrupt copying during copying, the copying machine temporarily stops when the last sheet of paper that is being copied is ejected, and enters the interrupt state. was. Therefore, even if, for example, a paper jam occurs until the end of one copy cycle (so-called cycle-out), the interrupt request will be accepted and the interrupt state will be established. It was difficult to determine whether the problem occurred during an interrupt, which caused confusion, and if the jammed paper required confidentiality, it would be difficult to maintain confidentiality.
この発明はかかる不具合を改善する1コ的でなされたも

維持するようにした電子複写機割込み複写制御方法を提
供して、割込み複写時化じる不具合による混乱の防止と
、機密保持の容易化を図ろうとするものである。This invention has been made to improve this problem, and when a problem occurs in which copying is impossible during cycle-out due to an interrupt request, the interrupt request is canceled and the original state is restored. Furthermore, an electronic copier interrupt copying control method is provided, which maintains the interrupt state by disabling the interrupt cancellation request if the above-mentioned problem occurs even during cycle-out when interrupt copying is completed, thereby preventing errors during interrupt copying. The aim is to prevent confusion caused by malfunctions and to facilitate confidentiality.

Figure 1 shows the control system of an electronic copying machine (not shown).
A microcomputer U consisting of a central processing unit CPU, memory RAM, ROM, etc., and an operation panel 1
an input/output interface 3 that inputs information selected by various switch groups (not shown) provided in the microcomputer U to the microcomputer U, and outputs display signals output from the microcomputer U1 to the display 2; It consists of an interface 5 for inputting and outputting control signals from the microcomputer U to and from the copying machine control system 4, and these operate as follows.

AMへ格納複写機本体を停止させる。When an interrupt switch (not shown) on the operation panel 1 is turned on in order to interrupt copying during copying, the microcomputer Ut detects this information via the interface and cycles out (stops) the copying machine. In addition to outputting a control signal to the copying machine control system 4 via the interface 5, the microcomputer U monitors any malfunctions that develop until the copying machine body cycles out, and if any malfunctions occur during that time, If so, take note of that information IJ R
Stop the main body of the copying machine stored in AM.

のルーチンの実行に移行する。When the last sheet of 10,000 copies is ejected, the copying machine body temporarily stops, and the process proceeds from step (2) to step (2) in FIG. At this point, it is determined whether or not the copying machine has stopped due to a problem that occurred on the verge of cycle-out. If the stop is due to a problem that occurred before cycle-out, proceed to step If so, proceed to step ■. In step (2), the contents stored in the memory RAM of the microcomputer U1 are examined and an interrupt request (!
It is determined whether or not to accept the interrupt cancellation request (interruption cancellation request). In step ■, it is determined whether the interrupt is already in progress, and if the interrupt is in progress, proceed to step ■ to maintain that state, and at the same time display that on the display 2; if not, proceed to step ■. , turn off the interrupt display. Further, in step (2), the copying machine main body enters a cycle-out state to enable interrupt copying, and when the interrupt copying is completed, it jumps to the subsequent copy processing routine and shifts to execution of that routine.

状態にセットされる。On the other hand, if the copying machine main unit stops due to cycle out and proceeds to step ■, it is determined in step ■ whether the interrupt switch is on (or off) or has been pressed again, and if it has been pressed again, proceeds to step ■. Determine whether or not an interrupt is currently in progress, and if the interrupt is in progress, proceed to step ■; if not, proceed to step ■, execute the above steps, and if the interrupt switch is on (or off). If so, proceed through the steps to determine whether the copying machine is operating. If the copying machine is stopped, proceed to step 11 to determine whether the interrupt indicator 2 is lit. If it is lit, proceed to step @ to determine whether an interrupt is currently in progress. If it is, the process proceeds to the subsequent copy processing routine, and if it is not in an interrupt state, the process proceeds to step (3) and is set to an interrupt state.

If there is an interrupt in progress, proceed to step ■ to restore the original state, then proceed to the subsequent copy processing routine, and if no interrupt is in progress at step The subsequent copy processing routine will now be executed.

It monitors for problems such as clogging, and if a problem occurs, the interrupt request is canceled, and if no problem occurs, it enters the interrupt state and interrupt copying is possible. Even if a jam occurs, it can be easily determined whether the problem occurred during copying in normal mode or due to an interruption, so there is no risk of confusion, and the person who is interrupted is copying documents that require confidentiality. was interrupted by
In addition, even if a paper jam occurs, there is no risk of problems such as the paper of the person who interrupted and the person who interrupted getting mixed up, making it difficult to maintain confidentiality. Moreover, there is no need for the person who interrupted the interruption to remove jammed paper caused by the person who interrupted the person's copying.
There is no need to take on extra time or work.
