PROBLEM TO BE SOLVED: To provide a solenoid drive circuit, which is capable of easily switching from one state of slowly reducing a current flowing through a coil to the other state of quickly reducing a current flowing through the coil and vice versa, where a current control means which applies a current to the coil or stops applying a current is provided between a power supply and the coil or between the coil and a grounding, and a diode, which allows a current to flow towards the power supply, is connected between the power supply and the grounding, bypassing the coil in the solenoid drive circuit. SOLUTION: A switching means 48 is provided between a power supply 45 and a diode 47 or between the diode 47 and the grounding. |
