[F] Entrance motor drive circuit

The entrance motor drive circuit controls the rotation and stoppage, rotational direction and motor cur- rent of the entrance motor.

The entrance motor is driven by pulse signals (MOT1-OUT1A, MOT1-OUT1B, MOT1-OUT2A and MOT1-OUT2B) output from the motor driver (IC1) under the command of a clock signal (TIOCA1), a rotational direction signal (MOT1-DIR) and current setting signals (MOT1-CUR1 and MOT1-CUR0) from the CPU of the finisher control PC board, and thus this motor rotates the feeding roller, junction roller and entrance roller.
