Abstract

PURPOSE:To count concentratively a copying sheet number of plural copying machines by a small number of registers and also a simple data processing. CONSTITUTION:Read pulses #1, #2, #3,- for designating each copying machine number are outputted from a driver 7 of a centralized control device 1. As for the first copying machine 2, contents of a copy pulse counting register 16 are sent out to a buffer register 6 by the designated read pulse #1. After a counting value is outputted, the register 16 is cleared. In the same way, as for the second copying machine 3 and the third copying machine 4, contents of copy pulse counting registers 17, 18 are sent out to the buffer register 6 by the pulse #2 and the pulse #3, respectively, and thereafter, said registers are cleared. In the centralized control device 1, for instance, when a counting value is sent from the copy pulse counting register 16 of the first copying machine 2, the buffer register 6 of an input/output device 8 is set, and contents of this buffer register 6 are inputted to an operating register 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for centrally counting the number of copies from each copying machine in one central management device for several copying machines.

In the conventional close-up copy number central counting device, registers are provided on both the copying machine control unit and each copying machine to store the number of originals and copies. Information indicating which page of the manuscript was being copied, or how many copies had been made, was being sent to the centralized control unit.

For this reason, multiple layers of registers are required not only in the central control device/format but also in each copying machine, and the data processing thereof is also troublesome.

Therefore, it is an object of the present invention to provide an apparatus that can centrally count the number of copies produced by a plurality of copying machines using fewer registers and through simple data processing.

In order to achieve this object, in the present invention, each copying machine is provided with a register for counting copy pulses, and the central control device is provided with a copy volume adjustment recorder corresponding to each copier 2 and a register for counting copy pulses of the copying machine. An arithmetic register is designed that receives the contents of the pulse count register via an online cable, subtracts the contents of the corresponding copy volume accumulation register according to the contents, and stores the result in the accumulation register. The contents of are aggregated in the central control unit in a fixed manner, and the aggregated hindlimb registers are cleared (.Therefore, each -a
For copying, only the copy pulse counting register is required, which reduces the number of registers required, and the central control device calculates the copy volume in real time, making the data processing simple. ing.

Note that the term "copy volume" used in the main draw indicates an integrated value expressed as (number of originals/sheets) x (number of copies).

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, three copying machines 2.3.4 are connected to a central management device 1 via online cables 5. As shown in FIG. Although there is no limit to the number of copying machines, in the following explanation, for convenience, an example using three copying machines will be explained.

The central control device 1 includes an input/output device 8 equipped with a buffer register 6 for reception, a driver 7 for reading/transmitting signals, and a locking unit for storing the copy volumes of each copying machine corresponding to the three copying machines. A display 12 that displays the contents of each register 9.10.11, and a display 12 that displays the contents of each register 9.10.11 and the contents of the buffer register 6 of the input/output device 8. The calculation register 13 is calculated according to the calculation result, and the result is stored in the corresponding stacking/renostar, and these registers, input/output devices,
The diffuser and the like are controlled by a controller 14.

The Copy 8J 2.3.4 is not provided with a register for accumulating the copy volume as in the prior art, but is only provided with a register for counting the number of copies generated each time a copy is made by the copying machine. That is, the copying machine 2 is provided with a copy pulse counting register 16, the copying machine 3 is provided with a copy pulse counting register 17, and the copying machine 4 is provided with a copy pulse counting register 18.
The output of 7.18 is output to the online cable 5. A read pulse from the driver 7 is also input to this register 16, 17, 18, and the contents of the register are sent to the buffer register 6 by the driver. Additionally, each register 16, 17, 18 is intended to be cleared when finished sending out its contents.

In explaining the operation, reference is also made to FIG.

In this figure, the first copying machine corresponds to the copying machine 2, the second copying machine corresponds to the copying machine 3, and the third copying machine corresponds to the copying machine 4.

The driver 7 of the central management device 1 sends a read/write command specifying each copier number: #/, #λ, #3, . . .
... is output. First copy? -2, the contents of the copy pulse count register 16 are sent to the buffer register 6 by the designated read pulse #/. In the example of Figure Ω, the 7th read pulse #/ and the 2nd read pulse #/
One copy pulse is generated between the
Therefore, by the second readout signal #/, the count value "2" is sent to the buffer register 6 through the online cable 5. After outputting the count value, the register 16
is cleared. Similarly, the contents of the copy pulse count register 1.7.18 are transferred to the buffer register by reading the second copy number 3 and reading the third copy number 3, and by reading the number 3. 6 and then cleared.In addition, in Fig. 2, each reading/gurus right ji
The number shown in ill indicates the count value to be sent out. In this way, the contents of the copy pulse count register for each copy are periodically compiled in the central management device. In addition, the copy pulse counting register only needs to count the number of copies, that is, the number of copies, between the seven designated readings and pulses, and the register's capacity can be extremely small. . Furthermore, for convenience of illustration, the interval between reading and gurus is shown as being longer, but since the processing time of the electronic circuit is considerably shorter than the copying processing time, the interval between IW reading and gurus is shown to be shorter. The copy pulse count register can also be configured with a frill-luff flop with / bits indicating 0 or /.

In the central control device 1, for example, when a count value is sent from the copy pulse count register 16 of the first copying machine 2, the buffer register 6 of the input/output device 8 is set, and the contents of this buffer register 6 are transferred to the calculation register 13. is input. At the same time, the contents of the integration register 9, which is provided corresponding to the first copy root 2 and in which the copy volume of the copy type is set (ie, reserved) in advance, is input to the calculation register 13. In the arithmetic register 13, the contents of the accumulation register 9 are subtracted by the contents of the buffer register 6 (and thus the register 16), and the result is stored in the accumulation register 9 again. Similarly, the contents of accumulation register 10 are subtracted by the contents of register 17 and the result is stored in register 10, and the contents of accumulation register 11 are subtracted by the contents of register 18 and stored in register 11. The contents of 9.10.11 are displayed on the display 12, and the remaining (in other words, reserved) copy volumes corresponding to each copying machine are displayed at all times. Ru. FIG. 3 shows an example of the display on the display 12.

In the above embodiment, the reading pulse is sent to the ship as a pulse designated by the copying machine number, but the driver for the input/output device of the central control device is provided corresponding to each copying machine, and the reading pulse is sent individually to each copying machine. Of course, it is possible.

According to the present invention, the number of copies from a number of copying machines can be processed in real time using seven online cables, and only a simple and small-capacity register is required on the copy side. The number of registers has decreased significantly, and
On the central control device side, the number of registers is reduced by dividing reading and reading into a series of time-sharing and reading.
Furthermore, data processing is simply performed only within the central management device.
