<p>PURPOSE:To provide a paper feed device in which blocking is not generated in the case of preventing partial wear of a double feed preventing roller by rotational movement. CONSTITUTION:This paper feed device is provided with a paper feed cassette of which the paper feed side end part of paper sheets 16 is projected from the extreme end part of a lift plate 1a, a one-way clutch 22 provided on the double feed preventing roller 2a side of paper feed roller pair 2 and rotating the double feed preventing roller 2a only in the clockwise direction, a rotationally moving member 20 having a projecting part 20a on the paper feed cassette 1 side and rotationally movably supported, and a link member 21 connecting together the rotationally moving member 20 and the one-way clutch 22. The one-way clutch 22 is driven through the link member 21, by rotational movement of the member 20 while the projecting part 20a of the rotationally moving member 20 is pushed with the paper feed side end part of the paper sheets 16. As a result, the contact part position of the double feed preventing roller 2a against the paper surface is changed.</p> |
