Claims

[Scope of utility model registration request]

Two sets of transistor circuits each having collectors connected to each other and emitters connected to both power supply terminals are provided, and a motor is connected between the collector connection points of the transistors of the two sets of transistor circuits. In a motor circuit configured to switch the direction of current flowing through the motor by switching on two transistors of different sets of transistor circuits, the direction of current flowing through the motor is changed by switching on two transistors of different sets of transistor circuits. a circuit that turns on two transistors to flow current to the motor in one direction, and turns off two transistors that were turned on by turning off the switch to cut off the current supply in the one direction; a circuit that charges a capacitor when the switch is turned on and discharges the capacitor when the switch is turned off;
A circuit that, during the discharging period of the capacitor, uses a discharge current to turn on two transistors in a different set from the two transistors that were turned on when the switch was turned on, thereby causing a current to flow in the motor in a direction different from the one direction. A motor circuit comprising:
