PURPOSE:To reduce circuit consumption currents at the time of a standby by installing a dummy signal receiver consisting of a photo-transistor, etc., to a remote controller for a motor opening and closing a window by a solar cell and transmitting a dummy signal prior to the transmission of a control signal. CONSTITUTION:A dummy signal receiver 3 consisting of a photo-transistor or a photo-diode is mounted on an infrared remote control receiver 1 set up to a controller 4 for a window opening-closing motor II driven by a power supply from solar cells besides a light-receiving module 2. A dummy signal is transmitted prior to the transmission of a control signal from the remote control receiver, and the light-receiving module 2 having large consumption currents is supplied with the power supply only at a required time at the time of the driving of the motor 11. Accordingly, circuit consumption currents at the time of a standby can be reduced. |
