Abstract: PURPOSE: To provide an inexpensive high-precision paper feed device by controlling rotation speed of a motor by a speed control loop until it reaches a predetermined speed before a target speed and controlling it also by a phase control loop after it exceeds the predetermined speed. CONSTITUTION: A speed command value is a signal of pulse rows having a certain interval and rotates and drives a motor M. Rotation speed of the motor M is detected by an encoder E1, and the detected signal is a signal of pulse rows having a predetermined interval. The control by means of a speed control loop makes pulse frequency of the signal detected by the encoder E1 coincide with the pulse row signal which is the speed command value. On the other hand, the control by means of a phase control loop makes pulse phase of the signal detected by the encoder E1 coincide with the speed command value. A difference between the speed command value and the signal detected by the encoder E1 is inputted to one terminal of a comparator 43 via an AFC 42 and the set value is inputted to the other terminal. Consequently, a switch 44 is connected when output voltage exceeds the set value.
