CONSTITUTION:In the figure, 10 is illustrating figure elements in the main body of a copying machine, and operation displays combining said elements with selection buttons are concentrated to the elements 10 and arranged on a display panel 20, where 11, 12, 13, 14, and 15 are components of an operation display, i.e. an ADF, a sorter, a magnification controller, a paper feed selector, and an optional paper feed selector, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation display device used in an electrostatic recording device, and more specifically, an operation display device for selecting a component attached to or provided in an electrostatic recording device and displaying the selected state. Regarding.

Electrostatic recording devices such as electrophotographic copying machines use, for example, an ADF that is an automatic feeder for copying originals, a sorter that has a function to organize ejected copy sheets, a variable magnification function that converts the magnification when copying from an original, They have come to have multiple functions such as multiple cassettes to accommodate a wide variety of copy sizes. Therefore, the selection operation method becomes cumbersome for the user of the electrostatic recording device, leading to erroneous or confusing operations.

First, to explain the conventional example using ADF selection as an example, as shown in FIG. 1, the selection button 1 and the display section 2 are provided in independent locations.
Sometimes they are located quite far apart. Now ADF
When you press the selection button, if the ADF is ready for use, display part 2 that says "ADF in use" will light up.
Indicates that ADF is selected. In other words, after the user finds the desired selection button from among a large number of selection buttons, the user presses that button to make the necessary selection, and a lamp located away from the selection button lights up or a display appears. It has been done. Therefore, the user is required to perform the selection operation after reading the instruction manual or display regarding the function of the selection button, and often makes a mistake in the operation procedure.

The present invention has been made for the purpose of eliminating the disadvantages of conventional operation display devices that can confuse users or cause erroneous operations. an electrostatic recording device equipped with an operation display device for selecting the component and displaying the selected state,
On the display panel, at least pictures of the automatic document feeder, the constituent elements of the sorter, and a picture of the electrostatic recording apparatus main body are arranged in a positional relationship corresponding to the arrangement of the constituent elements of the actual recording apparatus and the electrostatic recording apparatus main body, and The component diagram is a selection button, and by turning on the selection button, a selected signal is sent to the control circuit of the electrostatic recording apparatus main body, and the signal enables the control circuit to use the corresponding component. This is achieved by an electrostatic recording device equipped with an operation display device, which is characterized in that it sets a state and simultaneously displays a selected component diagram in a state different from that before selection.

Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 2 shows a front view of an embodiment of the operation display device according to the present invention. In the figure, 1
0 is a pictorial element of the main body of the copying machine, on which an operation display device consisting of a combination of component diagrams and selection buttons is arranged in a concentrated manner on the display panel 20. That is, 1
1 is an ADF, 12 is a sorter, 13 is a variable magnification, 14 is a paper feed selection, and 15 is an operation display device for selecting an optional paper feed. In FIG. 2, the selection button on the ADF operation display device 11 is selected and the diagonal line indicates that the selection button is lit.

FIG. 3 shows an example of a sectional view of the operation display device, and the display panel 20 is located at a location on the front or top surface of the electrostatic recording device where it can be easily observed and operated by the user. 21 is the key top,
Made of light-diffusing material such as plastic, e.g.
This is a pictorial diagram of the components of ADF11, etc.

The key top 21 also serves as an operation button for a selection switch SW on a printed circuit board 22 provided with a certain gap from the display panel 20, and a compressed return spring 23 is installed between the key top 21 and the selection switch SW. It is under pressure. Further, there is a miniature lamp L on the printed circuit board 22, and a partition wall 25 provided in the gap between the display panel 20 and the printed circuit board 22 forms a lamp house, and when the miniature lamp L is lit, e.g.
Key top 2 with a diagram of the components of ADF11 etc.
1 is illuminated from behind to indicate that it is selected. The selection switch SW is closed by pressing the key top 21, but when you release it,
Due to the action of the return spring 23, the key top 21 is pushed up and returned to its open state.

Figure 4 shows this control circuit. By pressing the selection switch SW, an alternate operation is performed and the selection signal SIG to the copying machine body is alternately turned on.
-Turn off. In addition, the circuit is such that the miniature lamp L lights up in synchronization with the ON of the selection signal SIG, illuminating the key top 21 which is a pictorial diagram of the component, and extinguishes the miniature lamp L in synchronization with the OFF of the selection signal SIG.

The power ON reset circuit section is for setting the output of the flip-flop IC3 to H level when the power is turned on, and the lamp L does not light up through the inverter IC4 when the power is turned on. Now select switch SW
When is pressed, a signal is input to the flip-flop IC3 via the waveform shaping Schmitt Trigger inverter IC1, the selection signal SIG is set to ON state ("H" level state), and the lamp L is also set to the lighting state, and this state is maintained. Furthermore, when the selection switch SW is pressed again, the selection signal SIG is reset and the lamp L is turned off.

As explained above, among the illustrations of the components (ADF, sorter, etc.) arranged in a positional relationship corresponding to the actual device on the display panel provided on the front or top surface of the electrostatic recording device, and the illustration of the recording device itself, When selecting the function you want to use (ADF, sorter, etc.), you can prevent erroneous operations by pressing the component picture itself that is a button to select the function.

In this embodiment, the structure is such that the key top, which is a picture of a selected component, is illuminated by a lamp, but of course the structure is not limited to this, and a light emitting diode or the like may be used instead of the lamp, or a component It is also possible to create a structure in which the elemental pictures themselves emit light as electroluminescence.

It is also possible to have a key-top structure using a transmissive liquid crystal display element in the component diagram, and it is also possible to use a reflective liquid crystal display element and omit the light source.
