DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a function switching means for a radio communication device, and more particularly to a radio communication device in which various functions are set by a limited function switching switch.

[0002]

2. Description of the Related Art In recent years, the functions of wireless communication devices have become diverse, and it is difficult to provide a number of changeover switches corresponding to each function. Therefore, one function changeover switch is used for changing over a plurality of functions. Then, the operation mode of the function changeover switch is switched by pressing the function switch or by a difference in pressing time.

FIG. 8 shows an example of such a wireless communication device.
8A, the operation modes of the three function changeover switches are simultaneously switched by pressing the function switch.

For example, a function changeover switch at the left end switches between a CALL function and a BELL function according to each operation mode. The indication of CALL and BELL is printed on the function changeover switch. In FIG. 8B, the display of CALL and BELL is printed on the panel.

[0005] As described above, unless there is a display indicating the current operation mode near the function changeover switch, the operation mode is difficult to understand and inconvenient. In addition, in the case of printing in different colors for each mode, the manufacturing cost is high.

Also, as shown in FIG. 8A, there is a drawback that the types of switches to be printed on switches are increased. Furthermore, when the number of operation modes is increased to three or four instead of two, there is a problem that a printing space is narrowed.

In order to solve the above-mentioned problem, there has been a device in which a display unit of a dot type display is arranged near a function changeover switch to change the display at the same place. An example will be described with reference to FIG. FIG. 9A shows a state in which the function changeover switch switches the CALL function in the operation mode.

When the function switch is pressed to switch the BELL function by pressing the function switch, the display section is placed at the same position as before as shown in FIG.
L is displayed.

[0009]

The prior art shown in FIG. 9 uses a display unit of a dot type display, but the dot type display has a high visibility such as readability of characters to be displayed. A design surface such as a character design is limited by the dot density. Attempting to display beautifully in an arbitrary shape not only requires an increase in dot density, but also increases the load on the drive circuit and software and increases the cost. Further, since each operation mode is displayed in the same place, there is a problem that the switching of the operation mode is difficult to be clearly recognized.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a dot type display by displaying a fixed display at the same place in each operation mode of a function changeover switch. An object of the present invention is to provide a wireless communication device capable of displaying an arbitrary shape neatly without using a display.

It is another object of the present invention to provide a radio communication device in which the display corresponding to each function changeover switch is simultaneously changed and its display position is changed at the same time, so that the switching of the operation mode is clearly recognized.

[0012]

According to the radio communication apparatus of the present invention, a plurality of operation modes are selected by operating at least one function switch, and the contents of the function of switching the plurality of function changeover switches in each operation mode are described. In a wireless communication device in which a plurality of functions are switched by the same function switching switch, a switching function content display area is provided near each function switching switch on the display surface of the display device, and the switching function content display area is Each of the function changeover switches is divided in accordance with the operation mode according to a uniform positional relationship, and the content of the function to be switched by each function changeover switch is displayed in the divided portion for each operation mode. It was done.

[0013]

According to the radio communication apparatus of the present invention, only the contents of the function for switching the selected operation mode of the function changeover switch are displayed near the function changeover switch, so that there is no mistake in the contents of the function changeover.

[0014] Further, by providing a fixed display at the same place, an arbitrary shape can be clearly displayed without using a dot type display. Also, the software and the driving circuit are simplified. Furthermore, the display corresponding to each function changeover switch is simultaneously changed and its display position is changed at the same time, so that the switching of the operation mode is clearly recognized. Further, there is no need to color-code the function to be switched for each operation mode of the function changeover switch, and the manufacturing cost is reduced.
