ABSTRACT:
A remote control device is designed such that it enables an object to be remotely controlled to execute an operation only by the user approaching the object to be remotely controlled. When the user who carries the transmitter 1 depresses an operation button A at a position distant from an automobile 2, the transmitter intermittently transmits a signal containing identification information and command information corresponding to the operation button A. As the user comes closer to the automobile 2 and enters an automatic operation area, the reception level of a receiver 3 exceeds a predetermined value, and the transmission signal is thereby received. The identification information and the command information of the reception signal are decoded, and an operation corresponding to the command information, e.g., door unlocking, is executed by an execution portion 4.
