Abstract
An automatic cut-sheet feeding apparatus includes a feed roller which rotates in a direction so as to feed in and feed out an upper most cut-sheet, and means for stopping the feeding of excessive cut-sheets which should not be fed out together with the uppermost cut-sheet when a plurality of cut-sheets are fed in together by the feed roller, and thereby automatically feeding cut only the uppermost cut-sheet of the stack of cut-sheet one by one, the stopping means includes a holder pressed against said feed roller, a push-piece supported on the holder and pressed at a position preceding a position where the holder makes contact with said feed roller along a direction in which the cut-sheet is transported thus causing excessive cut-sheets to curve downwards when a plurality of cut-sheets pass between the feed roller and the push-piece, and a stop surface disposed to confront a leading edge of the curved excessive cut-sheet and engage the leading edge thereof.
