The display unit 32 is provided on the upper surface of the digital copying machine 2 and is a liquid crystal display device having an input mechanism, and performs various operations such as enlargement and reduction of a print image, designation of print paper, designation of the number of prints, and the like. When a button is displayed and a finger or the like is pressed on a portion corresponding to the position of the button, a pressure-sensitive pressure-sensitive sensor made of a transparent electrode (not shown) senses and recognizes that the button is pressed. .

When the operation of the digital copying machine 2 is started, the display unit 32 displays an initial screen on the display screen 3 as shown in FIG. A plurality of buttons are displayed on the initial screen.

The buttons are not all the same color, and buttons used immediately, such as a copy start button, are set in a different color from the other buttons.

The screen is different when the copy mode is set (see FIG. 1), when the fax mode is set (see FIG. 2), and when the printer mode is set (see FIG. 3). Different colors are set, and the overall color is changed according to each mode. The color may be changed not on the entire screen but on a part of the screen, as long as the user can easily determine the contents when viewing the screen.

When the paper in the digital copier 2 runs out during use or when the paper is jammed inside the digital copier 2, an indication to that effect is displayed in a special color different from the normal screen color. It is displayed in a color, for example, a complementary color of the background color. When an important problem occurs, such as when the operation is stopped, a message to call a serviceman is displayed on the normal screen (see FIG. 4) in the upper column 5 as shown in FIG. The screen color is changed to a conspicuous color, for example, red. When the user displays a guide for removing a paper jam, a screen indicating the operation is displayed on the entire screen. Then, as the work proceeds, the color of the screen changes sequentially in accordance with the work progress.

When selecting the paper size, for example, FIG.
When the non-standard size button 7 (NonSTDsize) is pressed, a pop-up 9 for selecting a size is created. At this time, if the color of the portion of the pop-up 9 is the same as that of the background screen as shown in FIG. 6, it is difficult to recognize the color. Therefore, as shown in FIG. 7, the color of the pop-up 9 is different from the color of the background screen. Alternatively, reduce the color of the background. As a result, the pop-up 9 is greatly different from the background screen, and becomes clear and easy to understand.
