PURPOSE:To simplify a circuit by generating an analog control signal with a power operational amplifier and a variable resistance circuit and generating an analog drive signal with a voltage setting circuit and a power operational amplifier so as to establish the complete analog signal transmission system. CONSTITUTION:When a main body controller 150 is set to the input mode, a voltage setting circuit 103 generates an input voltage and applies the voltage to an analog control signal generating circuit 60 of a remote controller 50 via a power operational amplifier 114 in the constant current system. The circuit 60 receiving the voltage generates an analog control signal, sends the signal to a differential amplifier circuit 104 and the signal is sent to a main control circuit 100. In the case of the output mode, the circuit 100 generates an analog drive signal from the circuit 103 in response to the state of the control process and applies the signal to the controller 50 via the operational amplifier 114 in a constant voltage form to activate a lamp buzzer circuit 80. Thus, the system acts like the complete analog transmission system and the linearity of the analog control signal is improved with the simple circuit and remote control is implemented from plural locations.
