DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an operation display device for an image forming apparatus that displays function settings of the image forming apparatus on a screen.

[Conventional technology]

Conventionally, the operation section of this type of device is provided with various switches and indicators in proportion to the number of functions (magnification, concentration, etc.) the device has. For this purpose, the operation panel includes 1, for example, a cassette selection switch for selecting a desired cassette from among a variety of copy sizes, a cassette size display to display this, a magnification selection key for copying from an original, and a display to that effect. A magnification display 9 A group of switches necessary for duplex copy command and their display, A D F (Auto
A document feeder, its display, etc. are provided.

[Problem that the invention seeks to solve]

As the copying function becomes more complex, the number of switches and their indicators increases.

There are problems such as inexperienced operators being forced to perform complicated operations and having to reset settings many times due to operational errors.

In addition, conventionally, when a trouble occurs during a copying operation, such as a jam, no toner, no paper, etc., the display that notifies you only lights up or flashes. You must refer to the instruction manual to check the internal condition and recover it, or request maintenance by a service person.
There were problems such as a significant decrease in copying efficiency.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an operation display device for an image forming apparatus that allows a user to easily set complicated copying functions and perform trouble recovery operations while looking at the display. shall be.

[Means for solving problems]

The operation display device for an image forming apparatus according to the present invention includes a display means for displaying an explanation of settable copy functions and a copy function setting procedure in the form of a message and a functional block diagram on the same screen; A display control means is provided for displaying a function setting procedure for setting a desired function selected from among the copying functions on a display means in the form of a message and a functional block diagram.

[Operation] In the present invention, when a desired copying function is selected while viewing the settable copying functions displayed on the same screen as a message and a functional block diagram on the display means, the display control means selects the selected copying function. A setting procedure for setting a function is displayed on a display means in the form of a message and a functional block diagram.

If so, return to step (38), and if YES, transfer the information input from the operation panel, such as the number of copies, copy start, copy mode, etc. set up to the present time, to the main unit (40). 41), and causes the LCD display 1o to display a message indicating that the copying operation is in progress as shown in FIG. 5 (42).
Then, it is determined whether a jam has occurred during the copying operation 43), and if No, it is determined that the copying is completed 44).
If No, return to step (41); if YES, return to step (2).

On the other hand, if YES in step (43), the jam processing message and jam location shown in FIG. 6 will be displayed on the LCD.
Display the screen on the display 1o (45), and then
The operator performs the jam removal according to this display and determines whether the jam has been cleared (4B). If NO, the process returns to step (45); if YES, the message after the jam removal shown in Figure 7 is displayed on the LCD. Display the screen on the device 10 (47) 0 Next, it is determined whether the copy key 23 has been pressed (48), and if No, the process returns to step (47), and if YES, the process returns to step (40).

FIG. 10 shows the light detection sensor Sl shown in FIG.

It is a sectional view explaining the structure of S2, and 61 is a glass body, which is driven by an electrode substrate 62. 63 is a transparent acrylic plate that protects the glass body 61. θ is a viewing angle, which indicates the angle of attack of the eye relative to the glass body 61.

As can be seen from this figure, the light detection sensor Sl.

S2 is an acrylic plate 63 attached to the operation unit main body 21
It is arranged on the operation part main body 21 side with a gap between the upper and lower parts of the controller, and is configured to be able to detect external light A from the upper part and external light B from the lower part.

FIG. 11 is a block diagram showing the detection circuit of the light detection sensors S1 and S2 shown in FIG. They are connected in series to S2, and a reference potential vE is applied thereto. Reference numeral 73 denotes an amplifier that controls the light detection sensors sl and s according to the resistance value change of the light detection sensor S I * S2 (the resistance value varies depending on the amount of light).
Amplify the potential difference between the two. A contrast controller 74 outputs a contrast signal 74a for adjusting contrast to the LCD controller 9 in accordance with the output of the amplifier 73, thereby varying the contrast of the LCD display 10.

Next toUi! J. The operation shown in FIG. 11 will be explained with reference to FIG. 12.

FIG. 12 is a characteristic diagram illustrating the contrast adjustment operation, in which the horizontal axis shows the light amount ratio (Sl/S2) and the vertical axis shows the contrast.

For example, when the amount of external light A shown in FIG. 73 is lowered, and the potential of the contrast signal 74a output from the contrast controller 74 is lowered to suppress the contrast. Conversely, when the amount of external light B shown in FIG. Therefore, amplifier 73
The output of contrast signal 74a increases, and the potential of contrast signal 74a output from contrast controller 74 increases, increasing the contrast. Therefore, LC due to external lights A and B
The contrast of the D display 10 is constant.

Note that in the above embodiment, a case was explained in which a message and a function block diagram were displayed on the LCD display 10.
It is not limited to an LCD as long as it can display a bitmap.

〔Effect of the invention〕

As explained above, the present invention provides a display means for displaying an explanation of settable copy functions and a copy function setting procedure on the same screen as a message and a functional block diagram, and a display means for displaying a message and a function block diagram on the same screen, and a list of the copy functions displayed on the display means. Since the display control means displays the function setting procedure for setting the desired function to be selected in the form of a message and a functional block diagram on the display means, the user can easily set complicated copying functions and perform trouble recovery operations while looking at the display. It's easy to do, so
Copying efficiency can be greatly improved. Furthermore, since the copying function setting procedure can be displayed on one display, the number of displays can be greatly reduced, which is an excellent advantage.
