Abstract

PURPOSE:To prevent generation of a copying error by providing a display means which makes display by continuous lighting in the stage of an unmagnification mode and by flickering in the stage of a variable power mode and resetting automatically the variable power mode to the unmagnification mode upon lapse of prescribed time after the end of copying in the variable power mode. CONSTITUTION:A power source pilot 1 is lighted and a copying machine is warmed up when a power source switch is turned on. Copying is feasible from the end of the warm-up till print key on in a timing chart and the print key is lighted blue. The operator does not touch operation keys during this time and therefore the copiable stand- by state is displayed automatically in a standard operation mode. When the operator turns on the print key to perform copying in an unmagnification copy mode, the blue pilot lamp of the print key is put out and the red lamp is lighted. When the operator turns on, for example, a reduction 1 key in the case of a variable power mode, the unmagnification lamp is put out and the reduction 1 lamp is lighted. The print key is then flickered blue. When the operator pushes the print key in this state, the key is lighted red and is again flickered blue upon ending of the copying. Since the print key is flickered in different colors in the above-mentioned way, easy checking is made possible.

Description

[Detailed description of the invention] Keihan Bunka The present invention relates to a display device for a copying machine with a variable magnification mechanism.

Goose] U1 Right Modern copiers are equipped with various functions, and their operation has become complicated. In addition to the "Number Key" and "Print Button", there is a "Magnification Selection Key", "Interrupt Key", and "Paper Source Selection Key", and when peripheral devices such as 5ADF, ADF, and sorter are attached, there are even more. The operation mode of the control unit becomes more complex. For this reason, it is often the case that one of the many operation keys is forgotten, resulting in a copy error. The most common type of key operation section is the "magnification selection key." For example, in a copying machine equipped with a multi-stage variable magnification mechanism, the user: 1. Sets the original.

■, Set or check the transfer paper size.

■, Number of copies.

■、Set of variable magnification.

■、Print button ON.

The standard is to start copying by performing the following steps, but ■
Operation steps are often skipped as in →■→■→■, ■→■→■, or ■→■→■. The previous operator set the magnification to 1:C.
The copying operation is completed at 1,707, and the next operator sets the magnification to 1:
If you want to copy in step 1, you will make a copy error if you do not perform the operation in step 2 above. Thus, in general, 1:
If you want to copy at a magnification other than 1, you will not forget to perform operation (2), but if you want to copy at a magnification of 1:1, you will often not perform operation (2). Therefore, in a conventional copying machine equipped with a multi-stage magnification mechanism, when a certain magnification, for example 70.707, is selected and the conditions necessary for reduction of lenses, mirrors, etc. are automatically set, the ro, 707 selection key is pressed. A special display lights up in conjunction with this, but this is often overlooked and is not effective in preventing copying errors caused by forgetting to operate as described above.

Purpose The present invention has been made in view of the above circumstances, and is intended to prevent the occurrence of copy errors due to the difference in magnification in subsequent copying even if a variable magnification selection is made.

The structure of the present invention will be described below based on examples.

FIG. 1 is a schematic diagram of the operation section of a copying machine according to the present invention, where ■ indicates a power supply, and 2 indicates a count of the number of copies.

lights up and enters the warm-up state.

Next, with reference to the timing chart of FIG. 2, the display of the operation unit from the end of warm-up will be explained.

(1) Copying is possible from the end of warm-up to the print key ○N, and the print key lights up in blue.

During this time, since the operator does not touch any operation keys, the copy ready state is automatically displayed in the standard operation mode as shown below. However, displays that are not particularly relevant will be omitted.

0FF (2) When copying in the same size copy mode, when the print key is turned on, the blue display on the print key disappears and it lights up in red. When copying is complete, the red display disappears and the blue display lights up continuously.

(3) When copying in variable magnification mode, for example, reduction 1, when the reduction 1 key is turned on, the original size display disappears, the reduction 1 display lights up, and the print key flashes in blue. When the print key is turned on in this state, the print key lights up in red. When copying is complete, the print key flashes blue again.

(4) If the state described in (3) above is left unattended, the auto-shutoff function will operate after a predetermined period of time (for example, about 60 seconds) has passed after copying in variable magnification mode, changing the mode from variable magnification mode to normal magnification mode. and return to the standard operation mode (1) for the rest. Therefore, the print key will blink for about 60 seconds,
After auto-shutoff operation, the blue light will turn on continuously.

(5) When copying by switching from variable magnification mode to variable magnification mode, for example, when the reduction 2 key is turned on, the original size display disappears, the reduction 2 display lights up, and the print key blinks in blue. If the print key is turned on here, the print key lights up in red as in the case (3), and returns to blinking in blue when copying is completed. When the enlarge key is turned on in this state, the print key continues to blink in blue and the enlarge key is displayed. Then, when the print key is turned on, the print key lights up in red, and the process is the same as in (3) and (4) thereafter. In the above explanation, the print key is used to identify the normal magnification mode and variable magnification mode, but this may also be used by another key as long as it is easily visible to the operator. Further, a dedicated display means may be provided.

FIG. 3 is a control circuit block diagram of the main body of the copying machine.
Reference numeral 0 denotes an operation section having various operation keys and a display section, and transmits and receives signals to and from a microcomputer 42 via a gate array 41. In addition, status signals such as cassette size and lamp abnormality are input to the microcomputer 42 via the goo 1-array 41, and the microcomputer receives these inputs and operation inputs and performs optical control or transistor control. Various drive signals are output through the array 44. 43 is a power supply section.

Such a control section controls the display of the aforementioned operation section, automatic return from variable magnification mode to standard mode, and the like.

Effects As described above, according to the present invention, the print key or easily visible display 7, which is always used in copying work, flashes in a different color in variable magnification mode than in normal magnification mode. The operator can check whether the copy is currently in variable magnification mode or normal magnification mode, and automatically returns to the same magnification mode after a predetermined period of time has passed after copying in variable magnification mode, which prevents errors due to magnification differences. It can be prevented.
