PURPOSE:To control in a time division manner, to reduce the number of components, and to minimize a mounting space by providing a plurality of pulse motors, a common driving circuit, and a circuit for selectively supplying a voltage to the motors. CONSTITUTION:A controller 11 inputs pulse motor drive signals X, Y, Z to transistors QC, Q11, Q12, and inputs the signals X, Y, Z to transistors QD, Q13, Q14 through inverters 12a, 12b, 12c. The transistors QC, QD are selectively driven by the polarity of the signal X of the controller 11, i.e., a power source voltage VCC is selectively supplied to pulse motors C, D. Thus, the plurality of motors C, D can be controlled in a time division manner to reduce the number of components. |
