Abstract

PURPOSE:To rationalize the control of forms and arrangement of a copying machine by setting addresses by sizes of forms and reduction/enlargement rates, counting the quantity of copies is every use mode and storing it, and displaying the quantity when necessary. CONSTITUTION:The size of forms and a reduction/enlargement rate are inputted with a form size setting switch 1 and a reduction/enlargement rate setting switch 2, and the necessary quantity of copies is inputted as an input signal. Then, digital data is outputted to a bus 42 through an input interface. They are processed under the control of a CPU44 according to the program in an ROM43 and inputted to an RAM45 by modes, and a control signal is outputted from an output interface 46 to perform copying operation. Addresses are assigned to a nonvolatile memory 47, and cumulative values are stored by the modes. When a count display is requested with an input switch 3, the cumulative value of the counted value in the specified mode is displayed 5. Consequently, the utilization state of the copying machine is made clear and the supplement of forms and arrangement of the copying machine are rationalized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a copy number display control device for an electronic copying apparatus that is capable of displaying the number of copies for each paper size and reduction ratio.

[Prior art]

As a copy count control device for conventional electronic copying machines,
For example, there is a device in which a counter is counted up each time a sheet of paper is fed from a paper feed cassette, and the total number of copies is displayed on the operation panel. The number of sheets displayed in this @ meeting is the cumulative number of sheets fed regardless of the paper size and closing rate.

However, according to the conventional copy count display control device of an electronic copying device, only the total Oat It was not possible to know whether more or less paper of the size was being used. For this reason, it is difficult for users to plan paper purchases or supplies, and because it is not possible to know the number of copies to be used for each reduction ratio, users have to Unused line area ratio modes cannot be recognized, making it difficult to plan the purchase of a copying machine with an optimal detail ratio function when selecting a model for expansion or replacement.

[Object and structure of the invention]

The present invention has been made in view of the above, and in order to be able to display the number of copies for each paper size and reduction ratio, an address is set for each mode content and the number of copies for each mode is counted. The present invention provides a copy number display control device for an electronic copying machine, which stores a value and transfers and outputs it when a display request is made.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a copy number display control device for an electronic copying machine according to the present invention will be described in detail.

FIG. 1 shows an embodiment of the present invention, which includes a phase size setting switch 1 for specifying the desired paper size for copying, and a reduction ratio or enlargement ratio (for example, 50%, 8%) for the original size.
0%, 100%, 120%, etc.), a count display switch 3 that commands the display of the count value of the number of copies for each paper size and reduction ratio, and settings by each switch. Contents and operation details, as well as converting various input signals into digital signals, performing predetermined processing to calculate the number of copies for each mode, and various drive systems, corotron control systems, and image signal processing associated with electronic copying. a control section 4 that controls each of the above, and a count display device 5 that displays the number of copied sheets in each mode according to the mode instruction content of the count display switch 3 based on the count display information output from the control section 41. configured.

The control unit 4 has an input interface 41 that converts the contents of each switch and an input signal into a digital signal and outputs it to a bus 42, and specifies an address according to a program and mode specification for executing electronic copying, and sends data to the address. I'LOM 4 with psinogram that accumulates count values
3, an OPU 44 that executes control for electronic copying according to the program stored in the ROM 43 and also executes processing for counting the number of sheets for each mode, a RAM 45 that temporarily stores calculation results etc. by the 0PU 44, and a mode. Non-volatile memory 4 for permanently storing the number of different copies
7 and an output interface 7/8 46 which outputs control commands from the OPU 44 to each circuit and drive section and outputs count value data for each mode to the count display device 5.

Addresses are assigned to the nonvolatile memory 47 as shown in FIG. 2, and an area 47m from the first address to the address is used for control,
This area is secured as an area for calculation processing, and addresses are sequentially allocated for the subdivided modes ◆1 to φn starting from the address. For example, by assigning as shown in the following table and selecting the mode (≠1 to +n) to be displayed using the count display switch 3 when display is required, the cumulative count value within the corresponding address is sent to the count display device 5. be done.

In the above configuration, the operation will be explained based on the flowcharts of FIGS. 3 and 4. As shown in FIG. This mode signal is used to control the non-volatile memory 47 and the calculation area 47m.
Then, the address is set as shown in FIG. 2 in accordance with the mode. Using this set address, the number of sheets fed for each paper size in the paper feed cassette is detected and inputted as one of the input signals by the input interface 41, and the count value in the address is updated while performing cumulative processing in the CPU 44. .

On the other hand, as shown in FIG. 4, the process of displaying each mode using the count value in the address is performed by specifying the mode with the count display switch 3 (corresponding to the content of the previous mode). The address of the non-volatile memory 47 corresponding to the contents of this mode is stored in C.
Specified by the PU 44, the paper sheet count value within that address is transferred to the control and calculation area 47& of the non-volatile memory 47, and then the output interface 46'
e is output to the count display device 5, and the number of used sheets is displayed numerically based on the paper size and reduction ratio. Note that in the above explanation, each address is a combination of paper size and reduction ratio (for example, A4 paper, 70g6 or B5 paper,
100%, etc.), but it is also possible to store a count value of the next number of sheets to be used corresponding only to the paper size or reduction ratio (
For example, it may be displayed as "00 sheets of A4 paper" or "00 sheets of reduced magnification 70").

〔Effect of the invention〕

According to the above-described system and the copy number display control device of the electronic copying apparatus of the present invention, the number of used sheets can be displayed for each paper size and on the reduction ratio side, so the number of used sheets for the most frequently used paper size, etc. It is possible to know the number of sheets used at the most frequently used reduction ratio, and it is possible to predict the paper supply amount for each size according to the user's needs, predict inventory management, etc. Furthermore, when selecting a model for purchasing a new copying machine, replacing it, etc., it is possible to accurately select a model equipped with an optimal magnification function and a paper cassette.
