Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display control device for a multifunctional copying machine.

[Conventional technology]

In recent years, in addition to functions such as setting the number of copies and selecting paper size, copying machines have come equipped with a wide variety of special functions such as enlarged copying, reduced copying, analogue copying with different vertical and horizontal magnifications, and the formation of binding margins. .

On the other hand, in such a multifunctional copying machine, when the power is turned on, the basic information of the copying chamber is automatically set. The copy mode in which basic information is set is called the standard mode. Specifically, in this standard mode, for example, the number of copies is set to 1, the upper copy paper cassette is selected if multiple paper cassettes are installed, and the copy magnification is set to 1. The image is of the same magnification, the image density is at a standard level, and special operation modes (anamorphic copying, binding margin formation, etc.) are not selected.

Therefore, when copying in the standard mode, the copying machine operator can copy without having to input information regarding the operation of the copying machine through special key operations.

[Problem that the invention seeks to solve]

In this way, with multi-function copiers, when copying in standard mode, no special key operations are required, but when copying in a mode that is not set as standard mode, for example, when copying with a binding margin If you wish to make copies, set the binding margin by operating the binding margin setting key, and set the number of copies to 5 by operating the copy number setting key. Then, it is necessary to confirm the setting information such as the set function and the number of sheets by lighting the display element or the like.

As the number of additional functions increases in multifunctional copying machines, the number of function display elements also increases, and during operation, it is necessary to confirm the set special functions by checking the lighting state of the display elements. There were problems such as increased time and the possibility of malfunction due to incomplete confirmation.

[Means for solving problems]

This invention aims to solve the above problems.

That is, the display control device of the present invention provides a copying machine equipped with a plurality of function activation means and an input means for selecting a desired function activation means from the plurality of function activation means and inputting predetermined copy information. means for setting standard copy information in advance in a plurality of function activation means; comparison and judgment means for comparing and determining the standard copy information and the copy information of the function activation means inputted and selectively set by the input means; and the comparison judgment means. The present invention is characterized by comprising display control means for displaying only the copy information of the function activation means that does not match the standard copy information by the determination means on the display section of the function activation means.

[For production]

A special function operating means for multiple function operating means provided in a copying machine, such as a copying magnification changing function, an analog magnification function with different vertical and horizontal magnifications, a binding margin forming function, etc., is a key switch on the operation panel, etc. Values such as magnification, analog ratio, binding method, etc., are called copying information, but if this information is entered, the standard mode is set in advance when initial values are set before the copying machine operates. The copy information is compared and judged by a comparison judgment means comprising the input copy information tag and a microcomputer. Then, only when the two do not match, the copy information of the function operating means inputted by the display control means, which is also constituted by a microcomputer, is displayed on the display section of the function operating means.

The optical system drive signal and the exposure amount setting signal for maintaining the exposure amount at the set value are output, and are configured to control the respective drive mechanisms, exposure lamp dimming circuits, etc.

Next, its operation will be explained. When the copying machine is powered on, the CPU sets all control objects to their initial states. At this time, the standard mode is set as the copy mode. That is, the number of copies is set to 1, the paper feed cassette of the paper feed section is set to the upper stage, the copy magnification is set to 1x, the image density is set to the standard level, and analog copying and binding margin formation are set to a non-selected state.

As a result, the copy number display element 36 of the display unit displays l, the image density displays the standard level on the display element 41 (or the automatic exposure display 42), and the paper size display displays the paper stored in the upper cassette. A display element 44 of A4 size, for example, is lit.

Then, a copy magnification display element 50. Anamo rate display element 53
, special function display sections such as the binding margin display element 56 are turned off. This reduces the burden on the operator in checking the display.

The copier operator added 10 bindings to the 85-size paper and printed 5
When a user desires to make copies at the same magnification, the copy number setting key 33 is first operated to set the number of copies to 5, and the display element 36 displays "5".

Next, operate the paper size selection key 43 to switch the paper size display until the display element for B5 size lights up, and then
Select the paper cassette for size paper.

The copy magnification and analog ratio will not be changed, so do not press any keys. Therefore, these display elements 50, 53 remain off.

Next, operate the binding up and down keys 54 and 55 to
0mm is displayed on the binding margin display element 56, and the binding margin is set to 10.
Set to mm.

The copy conditions set through the above operations are input to the CPU 60.

When the power is turned on, in step S1, the initial state of the CPU is set, all control objects of the copying machine are initialized, and the copying mode is set to the standard mode.

Next, the process proceeds to step S2, where an internal timer used in the control routine is set. Proceeding to step S3, display control processing, which will be explained in detail later, is performed. Proceeding to step S4, key manual processing and other copying operation control processing are performed.

Proceeding to step S5, the previously set internal timer is checked, and after waiting for its completion, the process returns to step S2 to proceed to the next cycle.

Next, the display control processing routine will be explained according to FIG.

First, it is checked whether the copying magnification manually entered by the key is the same size (step 810), and if it is the same size, the magnification display element is turned off (step 511). If the magnification is not the same, the key is pressed and the set copy magnification is displayed (step 812).
).

Next, a check is made to see if the anamorphic rate manually entered is 100 (step 513), and if it is 100%, the anamorphic rate display element is turned off (step 814).

If it is not 100%, the key is pressed and the set Anamo rate is displayed (step 515).

Next, it is checked whether the binding margin manually entered by the key is 0, that is, no binding margin is set (step 816'), and if the binding margin is Otrrm, the binding margin display element is turned off (step 517). . If it is not 0tran, the key is pressed and the set binding margin is displayed (step 519).

Next, other display processing is performed, such as the number of copies, paper selection, image density, ready display indicating a copy ready state, and display of interrupt copy selection (step 519).
End display control processing.

An embodiment of the display control device for a copying machine according to the present invention has been described above. In this embodiment, when the copy mode is in the standard mode, the display sections of special functions that are not selected are turned off. This can also be displayed with low brightness. For example, in the case of forming a binding margin, if this is not selected, "0" may be displayed at low brightness.

Also, if a certain special function, such as the copy magnification change function, is selected and the copy magnification is set to a value other than the standard mode (equal magnification), and the copy magnification is set to the standard mode (equal magnification), Even in the standard mode, the set values may be displayed so that they can be confirmed. In this case, the light may be turned off after a certain period of time has elapsed.

FIG. 6 is a flowchart showing display processing when the above-mentioned copying magnification is taken as an example, and AB is replaced in the flowchart of FIG. In step 820, it is checked whether the magnification selection key has been pressed, and if it has not been pressed, it is checked whether the previously set copying magnification is the same size (step 521). When the magnification is the same, the magnification display element is turned off (step 522), and when the magnification is not the same,
If it is determined in step 820 that the magnification selection key has been pressed, the process advances to step 823, and the magnification set by the magnification selection key is displayed.

In the above embodiment, when the standard mode is selected as the copy mode, the display section related to special functions is turned off. It is also easy to provide a lighting key to light up the display.
