MEANDERING CORRECTION DEVICE, ROLL MEDIUM CONVEYANCE DEVICE, AND IMAGE PROCESSING DEVICE

摘要

A meandering correction device for a roll medium includes: a first roll medium conveyance unit; a second roll medium conveyance unit disposed downstream of the first roll medium conveyance unit in a conveyance path for a roll medium; a meandering correction roller located between the first roll medium conveyance unit and the second roll medium conveyance unit in the conveyance path and being vertically downwardly in contact with the roll medium to thereby apply a tension to the roll medium. The meandering correction roller includes a rotational shaft whose direction is changeable. A change in the direction of the rotational shaft causes a position of the roll medium in contact with the meandering correction roller to move in the direction of the rotational shaft.
