Abstract

PURPOSE:To repeat the copying work automatically again and again after a copy start button is operated once, by assigning a certain bit of a readable/ writable memory as an automaic start flag. CONSTITUTION:A program is stored which repeats automatically the copying work if the automatic start flag in a non-volatile memory 1 is set. A central processing unit 2 executes the processing in accordance with this program, and the unit 2 refers to the state of the automatic start flag after the copy start button is depressed once, and the unit 2 discriminates whether the control should be jumped to a subroutine, which is executed when the copy start button is depressed at the end of the copying work, or not in accordance with setting or resetting of the automatic start flag. That is, the automatic start flag in the non- volatile memory 1 is set in the service engineer mode. The copy work is repeated continuously until and operator operates a stop button, and a copying machine is stopped when the stop button is depressed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic start device for automatically repeating copying operations in a copying machine.

[Prior art]

Conventionally, some copying machines have a function that allows continuous copying within the maximum settable number of copies, but what is the maximum settable number of copies?
Automatically copies 2 times the number of lr nin sounds.

None have a device to start the cycle.

[Purpose of the invention]

This invention allows you to press the copy start button once without having to press the copy start button each time, even if you do not use the continuous copy function by setting the number of copies as described previously, when you want to make multiple copies in the same mode. The object of the present invention is to provide an automatic start device that allows multiple copies to be made without being constrained by whether or not the number of copies is within the maximum settable number of copies.
[Structure of the Invention] In order to achieve the above object, the present invention allocates a bit consisting of a readable and writable memory as an automatic start flag, and when this flag is set, once the copy start button is operated, the automatic start flag is set. This allows the copying process to be repeated over and over again.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 and FIG. 2 are block diagrams of a device according to an embodiment of the present invention and its control system, in which an automatic start flag is provided in a non-volatile memory that can be changed by a service engineer switch (S/E mode). , shows a case where the copying operation is automatically repeated by referring to the state of this automatic start flag.

In Figure 1, (1) is a readable/writable non-volatile memory that retains its stored contents even when the power is turned off. Changes can be made by operating the switch and entering service engineer mode. The address bit of such a non-volatile memory (11 bits) is assigned in advance as an automatic start flag, and this can be set to rlJ or ``0'' using the numeric keypad of the operator in the above service engineer mode. This sets the automatic start flag.If you want to be able to repeat the copying process automatically as described below, you can set the automatic start flag, or so-called This means that the automatic start flag has been set. (
2) is the central processing unit (CPU) of a microcomputer.
, (31 is a random access memory, (4) is a read-only memory (ROM), and this read-only memory (4) contains, as shown in FIG. A program is stored that allows the copying operation to be repeated automatically if the automatic start flag of After the button is pressed, the state of the automatic start flag is referred to, and depending on whether the automatic start flag is set, jumps to the subroutine that is executed when the copy start button is pressed at the end of the copy operation. Determine whether or not.

That is, as shown in FIG. 2, first, the automatic start flag in the nonvolatile memory (1) is set in the service engineer mode. That is, as mentioned above, the bit of the pre-allocated non-volatile memory 1) is set to rlJ or "0", and when the automatic start flag is set as rlJ, in order to make a copy. When the operator presses the copy start button to start the copy operation and execute the copy cycle, a determination result of YES is obtained in the step of determining whether the automatic start flag after the completion of the copy operation is set. This allows the copying process to be repeated automatically without the need to press the copy start button. This repetition continues until the operator operates the stop button, and when the stop button is pressed, the copying machine stops.

In this way, when you try to copy many times in the same mode, if the automatic start flag set in the non-volatile memo that can be changed in service engineer mode is set, you can use the copy start button once. The amount of secretion and movement
When the copy 0-work is completed, the operator jumps to the subroutine that is executed when the copy start button is pressed, so that the operator can automatically repeat the copy 1 work without pressing the copy start button. Therefore, you do not have to press the copy start button each time even in the same mode, and as long as you set the automatic start flag in service engineer mode, the copy operation will be repeated automatically, making it easier to operate the copy start button. You can save time and effort. Furthermore, when using the continuous copying function that allows you to set the number of copies as described above, you must set the number of copies even if the number of copies per copy is two, and the maximum number of copies that can be set must be set. Whereas there is a constraint on the number of sheets per sheet, there is no such problem with the structure.

In the above embodiment, the automatic start flag is provided in a nonvolatile memo that can be changed in the service engineer mode, so that the automatic start flag can be set while operating the service engineer switch inside the copier. However, the present invention is not limited to this; for example, the present invention is not limited to this. An automatic start flag is set in the random access memo (January 3), and a switch corresponding to the service engineer switch mentioned above is provided on the operation console, allowing the operator to select either of the above states as appropriate. You can do it like this.

〔Effect of the invention〕

As described above, this invention allows you to set the automatic start flag without having to press the copy start button once you press the copy start button, and to check whether the number of copies is within the maximum settable number of copies. Since the copying operation can be repeated automatically without any restrictions, it is possible to save the effort of operating the copy start button.

Claims (1)

[Claims] If the copy start button is operated with a read/write memory in which a predetermined bit is allocated as an automatic start flag and the above bit of this memory is set, copying will be started automatically by referring to it from now on. and means for controlling the copying machine to repeat the operation.
