[B] Paper pushing arm motor drive circuit

The paper pushing arm motor drive circuit controls the rotation and stoppage, rotational direction and motor current of the paper pushing arm motor.

The paper pushing arm motor is driven by pulse signals (MT10-OUT1A, MT10-OUT1B, MT10-OUT2A and MT10-OUT2B) output from the motor driver (IC49) under the command of a clock signal (TIOCC0),

arotational direction signal (MOT10-DIR) and a current setting signals (MOT10-CUR1 and MOT10- CUR0) from the CPU of the finisher control PC board, and thus this motor holds the paper with the paper pushing plate.
