When a control device of a motor controller simultaneously rotates a first DC motor and a second DC motor by controlling a first circuit, a second circuit and a third circuit, the second circuit is shared. Further, the control device controls each of switch elements of the shared second circuit by using pulse-width modulation. Accordingly, the drive of the first DC motor and the second DC motor can be controlled with high accuracy by the change of a duty ratio of each of the switch elements of the shared second circuit.
