Abstract
A circuit device for driving an electromagnetically movable unit at a high speed with a single power source such as a battery comprises a plurality of power transistors for inverting the polarities of the input power, a pair of control transistors connected via a NOT element to the control circuit of the transistors for turning then alternately on or off, and instantaneous double voltage generator connected to the output circuit of the power transistors. Rapid responsiveness of the circuit device can be obtained by magnetically driving the movable unit in both one way and return way without a conventional return spring.
