Recording sheet feeding device

摘要

First and second feeding roller pairs are disposed at positions upstream and downstream of a recording position to record an image onto a recording sheet. Each of the first and second feeding roller pairs includes a capstan roller and a pinch roller, which are located below and above a passage of the recording sheet. The capstan roller and the pinch roller has plural orbital grooves arranged along an axial direction, to relax the strain of the recording sheet with respect to the widthwise direction of the recording sheet. The depth of the orbital grooves of the pinch rollers are set to 0.3 mm, which is shallower than that of the orbital grooves of the capstan rollers. The shallow orbital grooves of the pinch rollers are capable of suppress the curl of the recording sheet effectively.
