Abstract

PURPOSE:To grasp exactly a state of a copying machine, and to prevent generation of a wasteful copying by flickering a variable power mode display lamp after a constant interval of time elapses, and also turning off a copying available lamp. CONSTITUTION:When a variable power mode is selected by a mode changeover switch group 2, a timer, etc. of a CPU1 are initialized, signals (a)-(d) and a flag signal (f) corresponding to a selected variable power from the CPU1 become a high level, and AND gates 5-8, 4 and 9 are opened. Subsequently, a corresponding variable power mode use lamp 13 is turned on, a copying machine becomes a copying available state, and when a signal (e) from the CPU1 is inverted to a high level, a copying available lamp 14 is turne on. In this state, unless copying is executed by operating a copying switch 3 for a constant interval of time or above the signals (f), (e) become a low level by time-up of a timer which is reset in response to the switch 3, the lamp 13 is turned on flickeringly by an oscillator 11, an operation of the switch 3 becomes ineffective, and also the lamp 14 remains turned-off. Accordingly, a copying state in case of copying of the next time is grasped exactly, and a copying error is prevented.

Description

[Detailed Description of the Invention] Technical Field The second invention is to change the display state of the operation unit in order to prevent an operator's erroneous operation when using the variable magnification mode in an i'+J variable magnification multifunction device equipped with a variable magnification mode. This invention relates to an improved adz display control device that normally controls displays.

<Prior Art> In a variable ratio copying machine equipped with a variable magnification mode, the optical 8-1. The drive meter is switched, and the display lamp corresponding to the specified variable magnification mode is lit. However, if the most frequently used mode is the same size mode, when the operator changes, the operator assumes that the current mote is in the same size mode and continues copying (the previously set variable size mode). There is a possibility that you may end up doing this. Conventionally, in order to prevent such erroneous operation by the operator, after a certain period of time has elapsed after copying in a specific mode, the display is forcibly switched to the most frequently used mode, for example, equal-size mode. I was trying to switch to .

However, with the device described above, it is difficult to set a fixed time to switch to the dark mode, and if the set time is too short, the operator may have to change the document and shear it. When the mode 1 automatically switches to 92 and especially at 2y, an erroneous multiple 1 which does not comply with the operator's intention is detected.
There was a possibility of doing j-.

<Objective of the invention> The object of the invention is to display the currently set variable magnification mode after a certain period of time has elapsed, rather than forcibly switching to the most frequently used mode after a certain period of time has elapsed. The lamp is blinking to inform the operator whether the current magnification change mode is in effect, and the copying operation is disabled to give the operator an understanding of the situation.
An object of the present invention is to provide a display control device for a variable magnification duplicator, which can make ψ ( ) ψ true and rainproof against useless duplication.

<Structure of the Invention> This invention includes a timer that is started at 14j (1 to mode selection), and a timer that is activated after a certain period of 114 hours has elapsed after the start of the timer.
When the copy switch is not operated, the display lamp of the currently selected displacement mode flashes and the copy enable lamp is turned off. If the close-up operation is not performed within the elapsed time, the variable magnification mode display lamp selected at that time blinks to prompt the operator to grasp the currently selected variable mode 1', and the copy enable lamp is displayed. Even if you accidentally operate the copy switch with the light off, the operation itself will be invalidated.

When the dial mode selection switch is operated as described above, the timer is activated, and the copy switch is activated within a certain period of time.
~(When no copy is being made, the set variable magnification mode indicator lamp is blinked, the copy iiJ indicator lamp is turned off, and the operation of the copy switch 3 can be disabled.

Flashing 4) To call the attention of the operator 6.
The blinking of the variable magnification mode display lamps on the two lenses allows the operator Q.2 to be reliably informed of the currently set mode. At this stage, if the operator wants to copy another mote, turn the copy switch :) to 1.
7. Operate the desired mode setting switch without making a Y operation.
After that, you can operate Suino Sen 3 for multiple duplication. At this time, even if the copying switch 3 is operated by mistake, the operation will be invalidated because the nest box 4 is closed, thereby preventing erroneous copying.

Note that when the mode set by n2 is the same magnification mode, timer 1 is not activated because n6=n2 and progresses unconditionally. For this reason, the timer 1 is reset and does not advance from n3- to n18, and the display lamp 14 of the copy layer remains lit for a period of time i<c. In the case of the 1x mode, the time is not regulated in this way because the 1x mode is set to mode 1, which is the most frequently used mode.

<Effects of the Invention> According to the present invention, if the copy switch is not operated within a certain period of time after the change mode is closed, then the Q setting is set. The variable magnification mode display lamp flashes and the copying operation 1'1 is omitted.The previous copying operation by the same operator and the current copying Even when the time is up, the display blinks to alert the operator to the operator's attention.
It is possible to prevent nobby. Also, if the previous operator left the variable magnification mode on, the multiple '5. After completing the program and after a certain period of time has elapsed, the next operator creates 1 to 1), and when the previous operator sets the magnification mode display lamp to 1, the variable magnification mode indicator lamp that was set last time is on, so the next time the operator At that point, you can correctly set the desired mote, and even if you miss the blinking display, the copy operation is disabled, so you can prevent copy mistakes. I wanted to.C
1. Miscopying can be effectively prevented even when the same operator performs the operation or when a different operator from the previous operation performs the operation.
