Abstract

A recording medium after printing which is discharged from a main body of a printer is guided from the main body to a support surface of a discharge support portion extending to a lower anterior side, and is wound as a roll body by a winding unit in a path that passes a tension roller. A tape-shaped elastic member is fixed on an end portion of a downstream side in a transport direction of the discharge support portion so as to extend in a width direction. An elastic friction surface is formed on the end portion of the downstream side in the transport direction of the support surface. A friction coefficient between the elastic friction surface and the recording medium is higher than the friction coefficient between a portion at an upstream side in the transport direction from the elastic friction surface in the support surface and the recording medium.

Claims12

Dependent claims

A medium transport apparatus, comprising:

a transport unit which transports a long medium to a downstream side;
a winding unit which winds the medium transported to the downstream side by the transport unit;
and
a medium support portion which is arranged between the transport unit and the winding unit in a transport path and has a medium support surface which supports the medium,
wherein a friction coefficient between the medium support surface at an end portion of the downstream side in the transport direction and the medium is higher than a friction coefficient between the medium support surface at an upstream side in the transport direction from the end portion of the downstream side and the recording medium, wherein the support surface is a continuous surface from the upstream side to the downstream side to thereby provide sliding resistance to the medium, wherein the end portion of the downstream side of the continuous support surface is at least partially curved.
