Abstract

PURPOSE:To properly control a motor by altering the driving condition of the motor according to the frequency of the occurrence of step-out of a stepping motor for driving a scanning optical system. CONSTITUTION:It is assumed that the stepping motor 19 is driven with a voltage V1 by driving a transistor TRQ1 before step-out. When the step-out occurs in each step, a TRQ2 is driven first to set the voltage to V2. And the scanning of the optical system is carried out again. Or the scanning is executed again by slightly delaying the rate of acceleration. At such a time, if the step-out occurs more, a TRQ3 is driven to set the voltage to V3 or the rate of acceleration is delayed. The motor can be controlled so that the step-out does not occur by such control.
