Claims

[Scope of claim for utility model registration] (1) In a portable television receiver equipped with a remote control function, the power of the television receiver itself can be turned on/off.
A remote control transmitter equipped with a power switch for turning off the power, and a power source that supplies power from the remote control transmitter by supplying power voltage to the control unit and remote control signal receiving unit for a certain period of time from the time the power is turned off. 1. A portable television receiver comprising remote control signal receiving means for receiving a switch operation signal. (2) In a portable television receiver equipped with a remote control function and operable by battery power or external power source, a remote control transmitter equipped with a power switch for turning on/off the power of the television receiver itself;
Means for supplying power supply voltage to the control unit and the remote control signal receiving unit even during the power off period when the external power source is operated, and maintaining the power switch operation signal from the remote control transmitter so as to be able to receive the power switch operation signal from the remote control transmitter at all times, and when the battery power source is operated The portable device is characterized by comprising means for supplying power supply voltage to the control unit and the remote control signal receiving unit for a certain period of time after the power is turned off, and maintaining the power switch operation signal from the remote control transmitter so that it can receive the power switch operation signal. television receiver.
