PROBLEM TO BE SOLVED: To prevent an operational failure attributable to disturbances and convert a wireless system to a wired system with ease. SOLUTION: In a remote control device of an air conditioning device which transmits a control signal transmitted from a terminal device 5 to a main body device provided in an air conditioning device by way of a communication device, the aforesaid communication device comprises a light emitting unit 5a, which converts a control signal into an optical signal, an optical communication cable 3, which transmits an optical control signal from the light emitting unit 5a and a receiving unit 2, which receives the optical control signal from the optical communication cable 3 and converts the signal into an electric signal so as to transmit the converted signal to the main body device, thereby preventing the penetration of disturbance noise to a communication channel and operational failures by transmitting operation control signals by way of the optical communication cable. |
