Each function control circuit of the controlled device is controlled based on the stored function control data.

When changing each control signal format stored in the storage circuit, the operation selection circuit instructs the control circuit to select a storage operation, and the storage selection circuit also instructs the storage circuit to select arbitrary function control data in advance. Then, the remote control signal to be newly stored is transmitted to the signal waveform analysis circuit, the signal waveform analysis circuit analyzes the received remote control signal, and inputs the control signal format into the storage circuit as an analysis result. At this time, the storage circuit rewrites the old control signal format corresponding to the function control data selected in advance by the storage selection circuit into the new control signal format.

Therefore, even if the remote control signal does not have a preset control signal format, if the control signal format of the remote control signal is stored in the storage circuit, the function control signal corresponding to the stored control signal format can be stored. can control the function control circuit of the controlled device.
