  • Portable telephone
    Patent number: 6915143
    Abstract: A portable telephone of the present invention comprises a casing, a LCD 18 and a key input device 20 disposed on a surface of the casing. The casing has a microphone 17 for delivering speech, a speaker 16 for receiving speech, a backlight 19 for lighting a screen of the LCD 18, a key light device 21 for lighting a manipulation surface of the key input device 20, and a control circuit 15 incorporated therein. The control circuit 15 checks whether a speech delivery signal input from the microphone 17 is a voice signal. If the speech delivery signal is a voice signal, display operation of the LCD 18 is set to OFF and both the backlight 19 and the key light device 21 are turned off. If the signal is not a voice signal, display operation of the LCD 18 is set to ON. Consequently, useless power consumption is reduced.
