Abstract:
1. A paper transporting apparatus transporting continuous paper to a paper processing part that performs designated processing on the continuous paper, comprising: a drive roller that transports the continuous paper in a forward direction with respect to the paper processing part and a direction opposite to the forward direction by a frictional force; a pre-centering mechanism, disposed upstream of the drive roller with respect to the forward direction, that regulates a position of the continuous paper with respect to a direction orthogonal to the forward direction and the backward direction by abutting against the continuous paper; and a tension increasing mechanism, disposed upstream of the pre-centering mechanism with respect to the forward direction, that increases tension on the continuous paper, wherein the tension increasing mechanism includes a roller that rotates in the forward direction at a circumferential speed slower than a transport speed of the drive roller when the drive roller transports the continuous paper in the forward direction, and that rotates in the backward direction at a circumferential speed faster than the transport speed of the drive roller when the drive roller transports the continuous paper in the backward direction.
