PURPOSE: To attain the miniaturization and light weight of a device and to reduce power consumption by stopping a booster circuit to boost and supply the voltage of a power source in a transmission part to a reception part while driving the transmission part.
CONSTITUTION: A remote controller A is provided with the transmission part 1 to transmit a control signal Y to an equipment B to be controlled, the reception part 2 to receive the control signal Y from the equipment B to be controlled, and a control part 3 to make the transmission part 1 transmit the control signal Y and to receive the control signal Y received by the reception part 2. The power source 10 is connected to the transmission part 1, and the voltage of the power source 10 is boosted at the booster circuit 11 further, and is supplied to the reception part 2. The booster circuit 11 is stopped at least while the transmission part 1 is driven.
