摘要： A paper transport apparatus that can reliably transport sheets of paper without the sheets overlapping or skewing, regardless of the type, size, thickness or condition of the sheets of paper. The paper transport apparatus includes a feed roller for feeding a sheet of paper along a transport path in a transport direction, and a retard roller for moving sheets of paper, other than a sheet to be transported by said feed roller, in a direction opposite to that of the transport direction. The feed roller and the retard roller are arranged in contact and in mutual opposition relative to the transport path. A rotational member is rotatably supported in opposition to the feed roller relative to the transport path. The rotational member is urged against the feed roller such that the rotational member can be moved away from the feed roller, at a location upstream of the position of contact between the retard roller and the feed roller, relative to the transport direction.
