Claims

[Scope of utility model registration request]

In a plunger solenoid drive device that linearly moves a plunger by converting electrical energy into magnetic energy, an induced voltage detection coil is provided in a part of the plunger solenoid and detects movement of the plunger and generates an output; The plunger solenoid is configured such that the product of a resistor that detects the current flowing in the drive coil of the plunger solenoid, the output of the induced voltage detection coil, and the voltage generated across the current detection resistor becomes a predetermined value. A plunger solenoid drive device that includes a control circuit that controls the current flowing through the drive coil.
