Patent ID: 8106743

Claim:
A remote controller that controls an electronic apparatus using radio wave, the remote controller comprising: an operation unit that has a changeover key for shifting the electronic apparatus from a standby state thereof to a normal state thereof; and a communication module that transmits to the electronic apparatus a power-on signal for shifting the electronic apparatus to the normal state thereof based on operation to the changeover key, wherein a period of transmission time of the remote controller for transmitting the power-on signal is longer than a period of off time of a communication module of the electronic apparatus in the intermittent operation thereof and is longer than a period of transmission time of the remote controller for transmitting other remote control signals; and wherein the communication module stops transmission of the power-on signal when receiving a response signal from the electronic apparatus in response to the power-on signal transmitted from the remote controller to the electronic apparatus even in the period of the transmission time of the power-on signal.
