Abstract (en)

A sheet feeding apparatus (4) comprising a sheet support means (5,6) for stacking and supporting sheets, a rotary sheet supply means (9) for feeding out the sheets stacked on the sheet support means, a rotary feed means (16) for feeding the sheet in normal and reverse directions with respect to a sheet feeding direction by pinching the sheet into a nip of the rotary feed means, and a rotation control means for prohibiting a reverse rotation of the rotary sheet supply means. A skew-feed of the sheet is corrected by the feeding of the sheet (5) in the reverse direction by means of the rotary feed means (16) and the control of the rotation of the rotary sheet supply means by means of the rotation control means. <IMAGE>
