A control circuit unit 5 for generating a control signal is provided. The control circuit unit 5 is also connected to a constant voltage circuit 6, an opening / closing unit 7, and a slave unit line signal detection circuit 8. The constant voltage circuit 6 performs rectification, smoothing, and step-down of the power supply voltage to generate a voltage at which each circuit unit can be driven stably. The switching unit 7 receives a control signal from the control circuit unit 5.
