Abstract:
A motor driving circuit includes a stepping motor driving circuit that controls driving of a stepping motor, a DC motor driving circuit that controls driving of a DC motor, and a control circuit that controls the stepping motor driving circuit and the DC motor driving circuit. The control circuit, upon accepting a driving instruction for driving the stepping motor in the middle of the DC motor driving circuit performing driving of the DC motor, stops driving of the DC motor by the DC motor driving circuit, and starts driving of the stepping motor by the stepping motor driving circuit.
