<p>PROBLEM TO BE SOLVED: To stably convey paper sheers one by one by keeping the pressing force between a roller and a paper sheet constant regardless of the loaded quantity of paper sheets. SOLUTION: Paper sheets 2 are loaded on a holder and pressed to a roller 5, whereby the roller 5 is rotated to convey the paper sheets 2 one by one in the direction of an arrow A. A side plate is provided with a guide groove 8 so that at the time of driving a rotating center shaft 7 of the roller 5 through gears 11, 4, 6 by a motor, the shaft can be moved downward without the change of meshing of the gears 4, 6, and the pressing force between the roller 5 and the paper sheet 2 is only the self-weight of the roller 5 (including the central shaft 7 and the gear 6) so as to be always kept constant.</p> |
