Abstract

PURPOSE:To surely prevent a buckling phenomenon and a two-sheet discharge phenomenon by fitting a separating roller which is adapted to rotate by only a predetermined angle in a sheet pay-out direction, overcoming an urging means, on a gate roller shaft. CONSTITUTION:When a pay-out roller 7 and an auxiliary pay-out roller 12 are rotated, the frontmost banknote A pressed by a pressing plate 4 is paid out through between the pay-out roller 7 and a gate roller 9 and through between a separating roller 20 and an idle roller 25. That is, when the first one of banknotes A is inserted into between the separating roller 20 and the idle roller 25, the separating roller 20 is rotated by a predetermined angle theta in the direction in which the banknotes A are paid out under friction force in the pay-out direction, and is locked at the rotated position. From this condition, the banknotes A are pulled out by the conveying force of the conveying path, and after the first one of the banknotes A is paid out, the separating roller 20 is reversed in the direction opposite to the pay-out direction due to the recovery force of a coil spring 23 so that it is returned to its original position.

The bills are fed out by rotating in the counterclockwise direction shown by the arrow in the figure. However, when paying out the bills A, which is weak and relatively easy to bend and has low rigidity, each O-ra 82.86f of the non-contact structure is used.
There was a problem in that a plurality of easily bendable banknotes entered the fll gap, resulting in inconveniences such as having to take out two banknotes, and the separation ability was reduced.

In summary, both the conventional separating roller contact type device and the non-contact type overlap type device have the problem that good feeding cannot be achieved due to the buckling phenomenon or the double-sheet dispensing phenomenon.

(c) Purpose of the Invention The object of the present invention is to provide a paper sheet feeding device that can reliably prevent the above-mentioned buckling phenomenon and double sheet feeding phenomenon and can perform good feeding.

(D) Structure of the Invention The present invention provides a method in which a feeding roller having an overlapping annular recess is fitted onto a feeding roller shaft, and a gate roller shaft parallel to the feeding roller axis is fitted into the annular recess in an overlapping manner.

(e) Effect of the Invention According to the present invention, even when feeding weak paper sheets, the first sheet is inserted between the separation roller and the roller that is in contact with the separation roller. Then, due to the frictional force in the direction of feeding out the paper sheet, the above-mentioned separation roller rotates by a predetermined angle in the direction of feeding out, against the urging force of the urging means.

Then, at a position where the minute wA roller has rotated by a predetermined angle, the minute 1i1 roller stands still, and after the sheet is fed out, this separation roller is reversed in the opposite direction due to the restoring force of the above-mentioned urging means.

(F) Effect of the invention As a result, by rotating the separation roller at a predetermined angle at the initial stage of feeding, the buckling phenomenon of paper sheets can be reliably prevented. As a result, the jammed next paper sheet is returned to its original state, so that the phenomenon of double-sheet feeding can be reliably prevented and good feeding can be achieved.
