PURPOSE:To exactly display the state of an device main body while interlocking with a remote control operation by adding a remote control device identifying code to indicate a remote control device, which transmits an operation signal to the device main body as an information to be transmitted from the device main body to the respective remote control devices, in addition to a state signal. CONSTITUTION:When an operating part 8a is operated in the remote control device A7a, a state display unit 9a is made to display ON, and at the same time, an ON operation signal (a) is transmitted to the communication controlling means 3 of the device main body 1, and its signal (b) is transmitted to an equipment controlling means 2. The equipment controlling means 2 receives the signal (b) and makes the operation to be ON, and at the same time, it turns an ON state signal (c) into the signals (d), (e) through the communication controlling means 3, and transmits them to the remote control device A7a and the remote control device B7b. By the way, when an OFF operation is performed by the operating unit 8a before the signal (d) arrives at the remote control device A7a, it makes the state display unit 9a display OFF, and at the same time, it is transmitted to the device main body 1 as an OFF operation signal (f). In this way, the state display unit displays ON or OFF quickly and exactly, and an operation without an operation error comes possible.
