Abstract

PROBLEM TO BE SOLVED: To easily discriminate a transmission reception mode by selecting a display color of a back light of a display section based on the selected mode. SOLUTION: Upon the receipt of a prescribed code from a key entry section 3, a CPU 4 controls a program stored in a ROM 1 to select a cellular communication means 9 or a PHS communication means 10 corresponding to an entered code. Then an entered identification code and a code registered in advance in the system are compared and when coincident, a display color of a back light 5 of a display section 6 is selected in red color when, e.g. the cellular communication means 9 is selected or in green color when the PHS communication means 10 is selected. Thus, which mode is selected is easily discriminated by having only to view a color of the back light 5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular / PHS portable telephone device in a multifunctional device such as a cellular / PHS mode, which performs color coding of LEDs such as a numeric keypad and a transmission key or a backlight of a display unit based on those modes. .

[0002]

2. Description of the Related Art In a conventional cellular / PHS mobile phone device, as a means for informing a user of which mode is set, a difference in ringer sound is disclosed as disclosed in JP-A-6-326655. I was listening.

[0003]

[Problems to be Solved by the Invention] Conventional cellular / PH
In the S mobile phone device, since it is possible to know which mode is set for the first time when the dial tone from the other party is heard, it is not possible to know which mode is set when calling from oneself. It was

Also, in the case of a system that automatically switches, the user had to confirm the display contents as to which mode he is currently in.

[0005]

SUMMARY OF THE INVENTION The present invention is to solve these problems and comprises a key input section for an operator to input operation and a display section for displaying input data from the key input section. In a cellular / PHS mobile phone device capable of switching between a cellular mode for calling via a cellular base station and a PHS mode for calling via a PHS base station, selection for selecting the cellular mode and the PHS mode And a cellular / PHS mobile phone device for switching the display color of the backlight of the display unit based on the means and the mode selected by the selecting means.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the cellular / PHS of the present invention.
FIG. 2 is a block diagram of a mobile phone device, and FIG. 2 is a flowchart of the cellular / PHS mobile phone device of the present invention. In FIG. 1, 3 is a key input unit for inputting data,
2 is an R for storing the data from the key input unit 3
AM, 1 is a ROM storing a program for controlling the operation of the present invention, 4 is a CPU for controlling the program stored in the ROM 4, 7 is a microphone for inputting voice, 8 is for outputting voice , 6 is a display unit for displaying data, 5 is a backlight capable of displaying the display unit 5 even in a dark place, 9 is a cellular communication unit, and 10 is a PHS communication unit. The operation will be described with reference to FIGS. 1 and 2. When a predetermined code is input from the key input unit 3, the system determines that the cellular communication means 9 or the PHS communication means 10 is selected according to the code. For example, the identification code of the cellular communication means 9 is "ABC", and the identification code of the PHS communication means 10 is "
XYZ ”, when the user wants to select the PHS communication means 10 having a low communication cost, the key input unit 3
If "XYZ" is input from, the data is compared between the input identification code and the code registered in advance in the system (step 10). When the identification codes match, the backlight is displayed in green as shown in FIG. 2 (step 20). Next, when it is desired to select the cellular communication means 9, if the identification code "ABC" is entered from the key input unit 3, the entered identification code and the code registered in advance in the system are compared. Is performed (step 10),
When the identification codes match, a red color is displayed on the backlight as shown in FIG. 2 (step 3).
0). Further, when the telephone number or the position information is automatically switched, the CPU 4 can judge and switch the color of the backlight 5. Furthermore, if the detector of the cellular communication means 9 or the PHS communication means 10 is used, the system is automatically switched using the detector, and the color of the backlight 5 is changed according to the switched mode. Switch.

[0007]

As described above, according to the present invention, it is possible to determine whether the transmission and reception are performed using the cellular communication means or the PHS communication means only by observing the color of the backlight. Can be made easier.
