<p>PURPOSE: To obtain a remote control transmission and reception device which is simple in structure and low in manufacture cost and can correctly contents by its reception device by adding a secret code and a function signal to transmit contents and sending a radio wave by its transmission device, and reading it on a reception side and implementing a function regarding a user's instruction when the read contents are the same with a previously set secret code. CONSTITUTION: A 1st secret code input means 11 consists of six selection switches which input secret codes and is able to input 64 kinds of secret code. The function signal which operates the robot system of a reception device 20 is outputted for the 1st time on condition that the secret code of the transmission device 10 and the previously set secret code of the reception device 20 match each other. For the purpose, the maker matches the secret code of a 2nd secret code input means 22 of the reception device 20 with the secret code inputted to a 1st secret code input means 11 of the transmission device 10 after this device is manufactured. Therefore, the secret code and function signals are both transmitted and then the secret code can easily be judged on the reception side, so that no extra device is needed.</p> |
