DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation button display device used for an audio device such as a stereo or a CD radio and a communication device such as a telephone.

[0002]

2. Description of the Related Art In recent years, an operation button display device has been disclosed in an open patent publication,
As described in JP-A-61-90381, the system includes a plurality of function groups each including a plurality of functions and control means for controlling each function in each of the function groups. Only the arbitrary function group switched by the switching means for switching to the arbitrary function group is controlled to be in an operable state, and a symbol representing each function of the arbitrary function group is displayed on the display and the displayed function is displayed. There is a configuration in which an arbitrary function is controlled by an operation of a corresponding operation unit. Also, by switching the plurality of function groups by the switching means, a symbol representing each function of each function group is configured to be displayed at an arbitrary position on the display, and by switching the plurality of function groups by the switching means. The range in which each function group is displayed on the display is set to be substantially the same.

[0003]

However, since the conventional operation button display device as described above has a plurality of function groups including a plurality of functions and means for switching the function groups separately, any function group display is required in advance. It is difficult to tell if
There is a problem that a plurality of function groups cannot be directly selected. Furthermore, although the operation unit and the display of the function group are in the same range, they are not the same, so that there is a problem that the user must move his / her eyes to the operation unit after viewing the display at the time of operation. .

[0004] In view of the above-mentioned conventional problems, the present invention displays a function group that exists in advance on an operation unit and directly selects an arbitrary function group, thereby making each function of the selected function group identical. An object of the present invention is to provide an operation button display device for displaying on an operation unit.

[0005]

In order to solve the above-mentioned problems, an operation button display device of the present invention is an operation button display device of a device provided with a plurality of functions each having a plurality of operation functions, wherein the function name is Display and several predetermined symbols or characters for the operation function of each function
A plurality of operation buttons having a display means for displaying the display unit, respectively, and the operation switch acting by the pressing provided corresponding to the operation buttons, a plurality of symbol display means of the operating button
Or, a control means for switching the character display unit in response to the function switching operation is provided, and the display of the initial state of the plurality of operation buttons is set to the function name display state.

[0006]

According to the present invention, the functions described above are displayed on the operation unit by the above-mentioned configuration, and by directly selecting an arbitrary function, each function of the selected function is displayed on the same operation unit by the symbol or character table.
This can be displayed as an indication, and the operation can be performed immediately after viewing the display without moving the line of sight to the operation unit during operation.
