 With the above-described configuration, the present invention enables timer control of a plurality of devices at substantially the same time with one remote controller. Fig. 6 is a flowchart showing a procedure for fetching remote controller signals of the microcomputer circuit 3 of the remote controller. As shown in the figure, the remote control signal from the key input section 1 is fetched by the microcomputer circuit 3 and it is judged whether it is a timer setting signal. If it is a timer setting signal, the memory 4 is made writable and the timer setting is set. The signal is written, and when the writing is completed, the timer 5 is driven. If the writing has not been completed, additional writing is performed to drive the timer 5.

The timer 5 inputs a signal to the microcomputer circuit 3 at the set time, the microcomputer circuit 3 reads the timer setting signal written in the memory 4 and inputs it to the encoding circuit 2, and the encoding circuit 2 corresponds to the input. The remote control code signal is generated and output and input to the modulator 6. The modulator 6 modulates the carrier wave with the remote control code signal and outputs the modulated carrier to the transmitter 7. The transmitter 7 then modulates the carrier wave. By sending the remote control signal to the antenna as a remote control signal and receiving the remote control signal by the receiving circuit provided on the side of the equipment to be controlled, the equipment can be controlled based on the information input to the microcomputer circuit 3 as the timer setting signal.
