Abstract

A power source circuit supplies positive and negative voltages to a DC motor. A first switching element is provided in a path for supplying a positive voltage from the power source circuit. A second switch-ing element is provided in a path for supplying a nega-tive voltage from the power source circuit. A driving circuit outputs an ON/OFF control signal for controlling the first and second switching elements to set them into opposite switching states to the first and second switching elements in response to a forward/reverse rotation instruction for the DC motor, and outputs an OFF control signal for setting the first and second switching elements into the OFF state to the first and second switching elements in response to a rotation interruption instruction. A short-circuiting circuit short-circuits both ends of the DC motor to brake the DC motor and interrupt the rotation thereof in response to the rotation interruption instruction.
