ABSTRACT:
A sheet feeding apparatus for an image forming device such as a facsimile machine, image scanner, copier, etc. Paper sheets are picked up from a stack of paper sheets and are fed individually to a pair of feeding rollers. In contact with the feeding rollers is an elastic film as a skew correction device. If the paper sheet picked up and fed to the feeding rollers is crumpled or askew such that a leading edge of the picked up paper sheet is not parallel to the feeding roller, the skewed paper sheet contacts the elastic film and the skew in the paper sheet is corrected by the elastic film. As a result, when the paper sheet is fed by the feeding roller, the leading edge of the paper sheet is parallel to the feeding roller and is thereby fed without any skew.
