WIRE REMOTE CONTROLLER COMMUNICATION DEVICE

The main system includes a first receiving unit(2) which is connected to the input port of a first microcomputer(1) for detecting the signal level of transmitted signal of the remocon unit, and a first transmission unit(3) changes the signal level of signal transmitted to the remocon unit from the first microcomputer(1). The remocon unit includes: a second microcomputer(1a) which generates control signal in the main system; a second receiving unit(2a) which detects signal level of the transmitted signal in main system and connected to the input port of the second microcomputer(1a); and a second transmission unit(3a) which changes signal level which is transmitted into the main system from the second microcomputer(1a).
