US 2004/0169326 A1 · Sheet feeding device

Abstract

A sheet feeding device includes a sheet feeding roller and a holder body. A separation pad is arranged on an upstream side, in a feeding direction of a recording medium, within a concave portion of a top surface side of the holder body facing a surface of the sheet feeding roller. On a downstream side of the concave portion adjacent to the separation pad, a low friction member is arranged in which at least a surface layer is formed of a material with a small coefficient of friction. Furthermore, a gap formation portion is formed in a surface of the concave portion where the low friction member is arranged and made higher than a surface where the separation pad is arranged. Additionally, by making the separation pad and the low friction member with the same thickness, when arranged in the concave portion, the surface of the low friction member is formed higher than the surface of the separation pad by the height of the gap formation portion.

Dependent claims

A sheet feeding device, comprising:

a roller that contacts and feeds recording media stacked in a sheet feeding portion;
a separation pad, having a surface with a coefficient of friction, that is pressed toward a surface of the roller;
and
a low friction member arranged adjacent to a feeding direction downstream side of the separation pad, the low friction member having a surface made a coefficient of friction smaller than the coefficient of friction of a surface of the separation pad, wherein the roller is arranged over the separation pad and the lower friction member, and a surface of the low friction member is positioned higher than the surface of the separation pad.
