Abstract

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.

Dependent claims

A device for feeding a sheet-type recording material along a passage which has a record position for recording an image, said device comprising:

a first feeding roller pair which nips and feeds said recording material toward a record position, said first feeding roller pair including a first pinch roller and a first capstan roller, said first pinch roller being located in a recording surface side of said recording material, and said first capstan roller being located in an opposite side to said first pinch roller with respect to said passage;
a second feeding roller pair which nips and feeds said recording material after passing said record position, said second feeding roller pair including a second pinch roller and a second capstan roller, said second pinch roller being located in the same side as said first pinch roller, and said second capstan roller being located in the same side as said first capstan roller;
and
a plurality of orbital grooves formed in an outer surface of said second pinch roller and arranged in an axial direction of said second pinch roller, the depth of said orbital grooves of said second pinch roller being within a range of 0.2 mm to 0.7 mm.
