PURPOSE: To enable the desired remote control at a desired time by outputting the infrared remote control signal, which is registered previously, to a device, to which the infrared remote control function is added, at a reserved time.

CONSTITUTION: When a reserved time input from an operation panel 1 and a real time coincide with each other, a timer control unit 3 requires transmit- receive to a remote control unit 5 through a timer switch 4. In the case that transmission is required, the remote control unit 5 reads out the infrared remote control signal from a control symbol storage unit 6, and the read-out infrared remote control signal is coded by an encoder 8, and is output from a remote control transmitting unit 10 to an object to be controlled. In the case that receive is required, the remote control unit 5 is used for registration of the infrared remote control signal at the time of reservation of a timer, and the remote control signal received by a remote control receiving unit 9 is decoded by a decoder 7, and a result thereof is registered in the storage unit 6. A display unit 2 displays a real time and the timer reservation condition or the like.
