A paper feeder roller wherein a motor transfers a driving force to a deceleration gear train. The deceleration gear train transfers this force to the shaft of a paper feeder roller which is rotated thereto. A plate connected to the paper feeder roller is rotatable about an axis so that the rotation of the plate rotates the paper feeder roller in and out of engagement with the deceleration gear train. When the paper feeder roller is disengaged with the deceleration gear train, the paper feeder roller can be rotated manually.
