摘要

A sheet feeding device of the present invention includes a feeding mechanism including a belt and a reverse roller, and circular collars or similar spacing members adjoining the belt for spacing the reverse roller and belt. When a single sheet is conveyed from a nip between the belt and the reverse roller to a preselected position downstream of the nip in the direction of sheet feed, the spacing member spaces the belt and reverse roller with the drive of only the belt or the drive of both of the belt and reverse roller being interrupted.
