The planetary gear unit includes a sun gear rotatable integrally with the drive shaft, and a planetary gear swingably movable about the sun gear while maintaining meshing engagement therewith. The transmission unit includes an input gear meshingly engageable with the planetary gear when the drive shaft rotates. The transmission unit transmits the driving force to the feeding roller through the drive shaft, the sun gear, the planetary gear, and the input gear.
