Abstract

PURPOSE:To stabilize the pressedly contacting force of a sheet to a paper sheet feed roller, and also to eliminate a jam or the like by providing an operating means by which a rear end regulating part is forwardly turned as the pushing-up plate moves upward. CONSTITUTION:Paper sheets P are fed one by one from the uppermost one as a paper sheet feed roller 100 rotates, and thereby the lower sheets are pushed upward. In this case, since an end regulating part 7 is obliquely formed, as the paper sheets P moves upward, the frictional force between the end of the sheet and the end regulating part 7 becomes less, and the sheets P move smoothly upward, and also the pushing force of the sheets against the paper sheet feed roller 100 is stabilized. Further, as the laminated thickness of the sheets P decreases, a rear end regulating part 15 is forwardly turned via an operating means 18 to push out forwardly the sheets P, so that the ends of the sheets abut on the end regulating part 7. Thus, the position of the end of the sheet P being in contact with the paper sheet feed roller 100 is nearly constant both in the state a large number of the sheets P are laminated, and in the state the remaining sheets are fewer.

In addition, as the push-up plate (8) moves upward, the rear end regulating portion (15) rotates about the fulcrum (16) via the wire (18), and the lower end portion gradually moves forward. The lower sheet (P) is gradually pushed forward in the paper feed cassette (1), and when there are few remaining sheets, the leading edge of the sheet (P) contacts the paper feed roller (+00). In a state where a large amount of sheets (P) are stored, the positions of the leading ends of the sheets (P) that come into contact with the paper feed roller (100) are almost the same.
