In a copier or similar electronic apparatus including a stepping motor, a device for controlling the drive of the motor loads control data for acceleration, constant-speed drive and deceleration stored in a ROM (Read Only Memory) or a RAM (Random Access Memory). The device controls the motor via a motor driver with the control data. This successfully reduces the load on a CPU (Central Processing Unit) due to the acceleration, constant-speed drive and deceleration of the motor, thereby implementing high-speed and accurate drive of the motor.
