なる選択駆動回路。In a selection drive circuit that selectively drives electrodes electronically, the collector of a grounded emitter transistor circuit is connected to a power source via a Zener diode and a first resistor, and from the connection point of the Zener diode and the first resistor. a first diode connected in a reverse direction in parallel between the base and emitter of the grounded collector transistor circuit; a second resistor connected to the collector of the grounded emitter transistor circuit, and connected to the connection point between the collector of the grounded collector transistor circuit and the second resistor so as to be forward-connected when the grounded emitter transistor is turned on. A selection drive circuit that supplies a constant voltage through a diode and takes out an output from a connection point between the collector of the grounded collector transistor circuit and a second resistor.
