Abstract

PURPOSE:To eliminate wasteful time and to improve the efficiency of copying operation, by announcing the end of exposure for the set number of copying sheets to the operator when said exposure ends. CONSTITUTION:When the operator operates a start switch for copying, a CPU1 controls first a driving circuit 7 for the copying machine to drive a copying machine body 6; at the same time, the CPU controls a control circuit 5 for a display device. On the other hand, scanning for exposure is started upon lapse of a prescribed time after the operation of the start switch for copying and thereafter, the exposing operation for the set number of sheets is performed. The CPU1 decide whether the exposing times coincide with the set number of sheets and turns on a pilot lamp for the end of exposure in a display device 4 at the prescribed timing for displaying the end of exposure thereby announcing the end of exposure. The pilot lamp for the end of exposure is provided in the above- mentioned way to indicate the end of exposure upon ending of the exposing operation, whereby wasteful time is eliminated and the efficiency of the copying operation is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of displaying the operation of a copying machine, and more particularly to a method of displaying a copying machine suitable for improving work efficiency such as document exchange work.

In conventional copying machines, the original is no longer needed once the last set of sheets has been completed, and although the operator can move on to tasks such as replacing the next original, it is not possible to know when this exposure is complete. Instead, time is wasted until the next copy permission display is displayed.

That is, FIG. 1 shows the operation timing of a conventional copying machine. When the operator operates the copy start switch (generally a copy button), (a) the main body drive device starts operating, and b) the copying starts. The OK indicator lamp turns off (C), and the copy-unable indicator lamp turns ON (d). Furthermore, after operating the copy start switch, exposure scanning begins after a predetermined period of time has elapsed, and thereafter, exposure operations for the number of cents are performed at predetermined timings (
,). Further, the copy-ready indicator lamp is turned on when exposure for the set number of sheets is completed and the document scanning device returns to the home position, and at the same time, the copy-not-ready indicator lamp is turned off. Also,
Normally, the copy-allowed indicator lamp and the copy-unable indicator lamp are built into the copy button together, and when the copy-ready indicator lamp is turned on, the light turns green, and when the copy-unable indicator lamp is turned on, the light turns red. informs the operator of the operating status of the copying machine. In this way, in conventional copying machines, the operator's judgment of when to start document replacement work was largely dependent on the display of the copy permission/non-copy indicator lamp, so as shown in the figure, the copy permission display is displayed after exposure is completed. One hour is wasted, and work efficiency is significantly reduced, especially when copying a large number of originals one by one. .

It is an object of the present invention to provide a display method for a copying machine that can eliminate the wasted time in the conventional apparatus and efficiently carry out copying work by displaying and informing the operator when exposure has been completed. purpose.

Embodiments of the present invention will be explained below with reference to the drawings.

FIG. 2 shows a block configuration diagram of a copying machine according to an embodiment of the present invention, in which 1 is a CPU, 2 is a key, and 3 is controlled by the CPU 1, and the key string ? - a key for controlling the code 2, a code control circuit, 4 a display device, 5 i;
l: A display device control circuit controlled by PU l and controlling the travel information device a; 6 a copying machine body equipped with various mechanisms such as copying machine transport, charging, exposure, development, transfer, separation, and cleaning; , 7 is a copying machine drive circuit that is controlled by the CPU 1 and drives the copying machine main body 6; 8 is a read-only memory (ROM) 9 in which each control program is set; and a random access memory (ROM) in which data can be written and read freely.

to be memorized.

Next, as shown in the operation timing chart of FIG.
When the operator operates a copy start switch (not shown), (a)
, the CPU 1 first controls the copying machine drive circuit 7 and drives the copying machine main body 6 according to the contents of the ROM 9 and RAM 10 (b). At the same time, the display device control circuit 5 is controlled to turn off the copy-ready indicator lamp in the display device 4 (c) and turn on the copy-not-ready indicator lamp (d). On the other hand, after a predetermined period of time has elapsed since the operation of the copy start switch, exposure scanning is started, and thereafter for the set number of copies (three times in this example).
Performs the exposure operation (,).

CPU 1 is memory 11 for the number of sets in RAM 10
and the contents of the sheet number counter memory 12 at a predetermined timing to determine whether the number of exposures matches the set number of sheets, and according to the result, at a predetermined exposure completion display timing (f). The exposure completion indicator lamp in the display device 4 is turned on to notify the operator of the completion of exposure (g).

At this time, the exposure completion display timing (f) is preferably immediately after the exposure operation of the copying machine main body 6 is completed, but may also be when the original illumination light source is turned off, after the exposure is completed, or after a certain period of time has elapsed after the original illumination light source is turned off. Furthermore, it can also be set when the document scanning device returns. On the other hand, the exposure count determination timing may be any time after the start of exposure and before the exposure completion display timing.

Next, when the document scanning device (not shown) returns to the home position, the copy-ready indicator lamp is turned on (C), and the copy-not-ready lamp is turned off. Further, when all the copy sheets are ejected from the copying machine main body 6, the copying machine drive circuit 7 stops its operation.

In this way, an exposure completion indicator lamp is provided in the display device 4, and this is displayed when the exposure operation in the copying machine main body 6 is completed.
By notifying the operator, the next document exchange operation can be carried out efficiently.

In addition, instead of providing an exposure completion indicator lamp in the display device,
As shown in timings (e') and (d') in Figure 3, the copy-ready indicator lamp turns on at the exposure completion display timing (C'), while the copy-not-read indicator lamp returns to the home position of the original scanning device. to turn off (d′),
It is also possible to display the completion of exposure with the same configuration as before without adding any special hardware.

Furthermore, when an exposure completion indicator lamp is provided, the display operation is not limited to the above embodiment; for example, the operation timing <g> in FIG. Good too.

Alternatively, change the operation timing in Fig. 3 from 0) to (g')
Alternatively, the exposure completion display rung may be flickered.

The operator may be informed of the exposure completion time by displaying a screen, letters, symbols, graphics, or even audio alone or in combination.

In addition, the installation location of the exposure completion indicator lamp should be
In addition to the flat panel, it may also be a document mounting table and its surroundings.

However, the present invention is applicable not only to ordinary copying machines, but also to copying machines that do not have a document scanning device, and to copying machines that can copy a large number of sheets with one exposure.

As described above, according to the present invention, when the exposure for the number of copies is completed, it is possible to notify the operator.
Copying operations such as document exchange operations can be performed efficiently, and the overall operation time can be greatly shortened. In addition, if the timing of exposure completion is displayed audibly, the operator can know the timing of exposure completion while doing other tasks such as taking out copies, arranging copies, checking density, etc. This further improves work efficiency.
