REMOTE CONTROL DEVICE.

摘要

A first carrier signal generation circuit (15) generates a carrier signal (S1) of a first frequency used for the frequency-modulation of a preset identification code (S). A second carrier signal generation circuit (16) generates a carrier signal (S2) of a second frequency which is different from the first frequency. A modulation circuit (14) adds the carrier signal (S2) to the identification code (S) frequency-modulated by the carrier signal (S1) for a certain time, and outputs the resulting signal to a light emitting circuit (17). When a learning remote control device of a type which always modulate a signal with the first frequency tries to store the code (S), the carrier signal (S2) of the second frequency is also demodulated by the first frequency, and subjected to data compression. Therefore, the amount of data of the identification code (S) exceeds the capacity of storage of the learning remote control device, and the storage of the code (S) in the remote control device can be prevented.
