Abstract

A paper sheet feeding apparatus includes a driving motor having a driving gear rotatable in forward and reverse directions, a first driven gear engaged with the driving gear and rotating only in the forward direction, a second driven gear having a different number of teeth than the first driven gear and rotatable only in the reverse direction, a pick-up roller, driven by rotation of the first or second driven gear, for picking up paper sheets, a paper sheet feeding roller for feeding paper sheets picked up by the pick-up roller, a separating roller for separating, one by one, paper sheets which are supplied from the paper sheet feeding roller, and a resist roller for aligning the paper sheets supplied from the paper sheet feeding roller. The speed of the paper sheet feeding apparatus can be changed in accordance with the speed of an image forming apparatus to which the paper sheet feeding apparatus is connected.
