ことを特徴とするソレノイド駆動回路。 It comprises a series circuit of a first resistor and a solenoid, and a switch means provided to selectively short-circuit the first resistor, and the voltage applied to the solenoid is controlled by short-circuiting or non-short-circuiting the first resistor by the switch means. In the solenoid drive circuit configured to change the solenoid, a diode is connected between a common connection point between the first resistor and the solenoid and one end of the switch means in a direction in which current flows from the switch means side to the solenoid, and a diode is connected in parallel to the diode. What is claimed is: 1. A solenoid drive circuit comprising: a connected capacitor; and a second resistor connected to one end of the switch means and forming a charging path for the capacitor via the first resistor and the capacitor while the switch means is off.
