The signal from the terminal device is modulated by the frequency f2 in response to the state of the switches S1a-Snc and an infrared ray is transmitted as a response signal. The response signal is received by a receiver Rx of the center, the control section CONT discriminates simply the state of the switches S1a-Snc of each terminal device from the time difference between the transmission time of the pulse D0 and the response signal.
