<p>PROBLEM TO BE SOLVED: To effectively prevent the occurrence of defective feed, such as the double feed of paper sheets loaded in a mixed state. SOLUTION: When long paper sheets and short paper sheets are loaded in a mixed state, a resistance member 20 to regulate movement, in the reverse direction to a paper conveyance direction, of the short paper sheet is arranged upper stream of a paper conveyance direction from the rear end of the short paper sheet and in a position where width is reduced to a value slightly lower than the paper width of the short paper sheet. A suction duct 161 to guide a flow of air sucked by a fan is set in such a manner that a distance L3 from the forward end of the paper sheet is higher than a distance L2 from the rear end of the paper sheet to the resistance member 20. As a result, since, even when air 17a for separation is blown against the short paper sheet, movement in a reverse direction to a paper conveyance direction of the short paper sheet is regulated within the L2 by the resistance member 20, the short paper sheet is reliably sucked to the conveyance belt 15 side and reliably fed.</p> |
