Abstract

PURPOSE:To reduce a cost, and also to simplify an operation by constituting so that a copying machine operating condition which is set at the time of a regular start can be changed and selected by a copying machine operating condition selecting and operating member. CONSTITUTION:A control mechanism 40 is switched to a copying machine operating condition selecting mode by executing an operation which is different from a regular copying machine start operation, and in this state, a copying machine operating condition is selected and inputted to the control mechanism 40 by operating a copying machine operating condition selecting and operating member on an operation panel 20, for instance, a copying magnification selecting switch, and thereafter, a storage operating signal is inputted to the control mechanism 40, by which its copying machine operating condition is stored in a nonvolatile memory 26. In this way, it is unnecessary to install a mechanical switching mechanism, therefore, the cost is reduced, and also its operation can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a control device for a copying machine, in particular, a copying machine operating condition such as copying magnification, tray type, use or non-use of a sorter, etc., which is always set when the copying machine is normally started. The present invention relates to a device that performs control so that

Conventionally, in copiers that can change the copy magnification in multiple stages, have trays of different sizes, or are equipped with a sorter, when the copier normally starts up, it displays the copy magnification, tray type, sorter used, unused, etc. The operating conditions of the copying machine are always controlled to be constant, for example, 100% copy magnification, 84 size tray, and no sorter in use.

In order to change and set the copying machine operating conditions, a mechanical switching mechanism such as a selection switch installed inside the copying machine body is used.

For this reason, a mechanical switching mechanism must be installed inside the copying machine, which increases the cost and requires switching the mechanical switching mechanism in a narrow space, which makes the operation cumbersome. It has the following defects.

The present invention has been made in view of the above circumstances, and its purpose is to enable the copying machine operating conditions that are set when the copying machine is normally started to be changed and selected by using the copying machine operating condition selection operation member on the operation panel. An object of the present invention is to provide a control device for a copying machine.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic explanatory diagram of a copying machine, in which a photoreceptor 2 is installed inside the main body 1 of the copying machine, and around the photoreceptor 2 there is a charger 3,
A developing device 4, a transfer device 5, a cleaning device 6, etc. are arranged in sequence, and an exposure optical system consisting of an exposure lamp 8, an imaging lens 9, etc. is located below a platen glass 7 provided in the copying machine body 1. 10 is provided, and is configured to expose the original f15 image on the platen glass 7 onto the photoreceptor 2 to form an electrostatic latent image.

Inside the copying machine main body 1, there is a first. Second. Third paper tray Il
+, +12 and 113 are provided so that the copy paper is conveyed from any one of the paper trays 11 toward the transfer device 5. 12 is a fixing device.

The copying machine main body 1 is provided with an operation panel 2o, and the operation panel 20 includes a copy start button 21 and a first button 20 serving as a copying machine operating condition selection operation member. 2nd and 3rd paper tray selection switches 22+, 222.223.

A plurality of copy magnification selection switches 23, a copy number setting switch group 24, a display group 25, etc. are also provided.

Then, with the power on switch 30 turned on,
When operated in the same manner as before, the control mechanism 40 controls the operation of each device to obtain a copy through a predetermined copying process.

Note that since this operation is conventionally well known, its explanation will be omitted.

As shown in FIG. 3, the control mechanism 40 includes a control section 41 and a recess M42 for giving drive commands to the control section 41. Various signals are input to the control section 41 from the operation panel 20, and when the power is turned on, A signal is input from the switch 30, and based on the input signal, the photoconductor 2, charger 3, and developing device 4 are activated.
, transfer device 5, cleaning machine 6, exposure optical system 10, etc., in ROM4
2) to perform the copying operation according to the program 101], and the copying machine operating conditions (copy magnification, tray size, , whether the sorter is used or not, etc., the various operating condition switching means are driven to set the selected operating condition when the copying machine is normally started.

The operation will be explained below.

First, press the number button (9) of the copy number setting switch group 24,
The copy start button 21 and the power-on switch 30 are pressed to switch the control mechanism 40 to the self-diagnosis mode.

In this state, press the auto clear button CL to clear the control mechanism 40.
When the setting status check signal is input to the control mechanism 40F,
i. Light the lamps 2 to 22t and 23' on the operation panel 20 that correspond to the set operating conditions of the copying machine.

In other words, each lamp corresponds to each switch, and when the copier operating conditions corresponding to that switch are set, the lamp corresponding to that switch turns on.

For example, when the first paper tray 11 and 70% copying magnification are set, the first paper tray selection switch 22.
The lamp 22'I corresponding to 7 (1% compound magnification selection switch 231) and the lamp 23'1 are lit.

This allows you to check the set copying machine operating conditions.

and optional switch 22. ~22. , 23' to change and select copying machine operating conditions.

The copy machine operating conditions selected for this change are as described above.
It can be confirmed at 2- to 22'l and 23'.

For example, the second paper tray selection switch 22. Press 2nd paper tray 11. When set, the lamp 22S lights up.

Thereafter, when the copy start button 21 is pressed and a storage operation signal is input to the control mechanism 40, the selected copying machine operating conditions are stored in the nonvolatile memory 26.

As described above, the control mechanism 40 is switched to the self-diagnosis mode (that is, the copying machine operating condition selection mode) K by performing an operation different from the normal copying machine startup operation, and in this state, the operation panel 2o
By operating the copying machine operating condition selection operation member (e.g. copy magnification selection switch 23, paper tray selection switch 22, etc.) above, the copying machine operating condition is selectively inputted to the control mechanism 4o, and then the storage operation signal is input. By inputting it to the control mechanism 40, the selected copying machine operating conditions can be stored in the nonvolatile memory 26.

Then, by turning off the power supply switch 30'k, the control mechanism 4o returns to its initial state, but the copying machine operating conditions stored in the nonvolatile memory 26 are not cleared and continue to be stored.

This completes the operation of selecting copying machine operating conditions.

Next, when the power supply switch 3o is turned on to start the copying machine in the normal mode, the control mechanism 40 is switched to the normal mode and based on the copying machine operating conditions stored in the non-volatile memory 26, The copying machine operating condition switching mechanism is switched to set the selected condition, and the lamp corresponding to the selection switch is turned on.

The present invention is as described above, and the copying machine operating conditions that are set when the copying machine is normally started can be changed and selected by using the copying machine operating condition selection operation member on the operation panel.

Therefore, since there is no need to install a mechanical switching mechanism, the cost is reduced, and since the operation can be performed from the operation panel, the operation becomes easy.
