Title: Paper sheet handling device
Inventor: FUKUTOME YOSHIO
IPC: B65H83/02
Filed: 1993-05-26
Abstract: PURPOSE:To form a handling device compact without degrading performance of a paper sheet stacking and supply mechanism by eliminating paper sheets biting at an overlap part after completion of feeding action by rotation of a blade-equipped roller for returning biting. CONSTITUTION:A containing box to in which a group 3 of paper sheets are stacked and stored is composed of side plates, a gate roller guide member 4, and a vertically movable bottom plate 2. After completion of the paper sheet feeding, for eliminating a subsequent paper sheet P4 in a biting condition close to an overlap part, the bottom plate 2 is lowered for a specified quantity from the paper sheet P4 biting condition to form space between the paper sheet group 3 and a supply roller 11. Next, a feeding roller shaft 9 is rotated by a specified angle in a counter feeding direction, so the paper sheet P4 in the biting condition close to the overlap part is dropped onto the paper sheet group 3 to be set in order by a blade-equipped roller 8 for returning biting which is provided with resilient members at a constant pitch along a half-circle. Sizes of a paper sheet stacking and feeding mechanism can thus be made small to provide a compact device.
