ABSTRACT:
This specification discloses a device for feeding sheet-like image-bearing members (hereinafter simply referred to as sheets) cut into a predetermined size and used with copying machines, recording apparatuses, printing machines and the like. More particularly, it discloses improvements in a sheet feeding device having a feed roller for feeding one by one sheets piled on a paper feed bed or in a cassette or the like, said roller having a cross-section in which part of the circumference thereof is cut away so that, during the non-feeding, the uppermost surface of the piled sheets and said roller maintain a non-contact condition with the aid of said cut-away part. The sheet feeding device is characterized in that it has a member for depressing the piled sheets substantially to a predetermined position before said roller contacts the sheets, in order to always maintain constant the position whereat said feed roller first contacts the sheets. The sheets commonly used with the copying machines and the like are sheets of plain paper or sheets of paper having chemicals applied thereto.
