【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. The drawings show a bill feeding device, and in FIG. 1 and FIG. 2, a receiving plate 1 arranged substantially horizontally is provided, and the lower side of the receiving plate 1 is set in the bill storing section 2 and the receiving plate 1 is opened. The mouth portion 3 is formed, and a part of the peripheral surface of the pickup roller 4 is exposed from the opening portion 3 into the bill storage portion 2 described above.

Further, a feeding roller 5 is arranged on the feeding side. The feeding roller 5 is formed by integrally separating two roller portions 5a and 5b from each other, and a non-rotating gate roller 7 is disposed in a concave portion 6 for overlapping between the roller portions 5a and 5b. On the other hand, a pair of conveying rollers 8 which are vertically opposed to each other are arranged in the next stage of the above-mentioned feeding roller 5.

Here, the delivery roller 5 and the gate roller 7 are rollers whose peripheral surfaces are made of rubber, and the overlap variable mechanism 9 is attached to the gate roller 7. That is, an inverted L-shaped roller support arm 10 is provided, the intermediate portion of the roller support arm 10 is pivotally supported by a support shaft 11, and the roller support shaft 10 is provided on the upper end portion of the roller support arm 10 via the roller support shaft 12. , A coil spring 13 for biasing the gate roller 7 in the overlap direction is urged to the lower end portion of the roller support arm 10, and the lower surface of the lower end portion of the roller support arm 10 described above is urged. When a banknote X passes between the feeding roller 5 and the gate roller 7 described above, a stopper 14 for position regulation is provided, and the gate roller 7 is attached to the coil spring 13 as shown in FIG. It is configured to allow backward movement in the direction in which the amount of overlap is reduced against the influence of power.

A large number of banknotes X, which are urged toward the receiving plate 1 by a pressing plate (not shown), are stored in the banknote storage unit 2 described above, and when the pickup roller 4 and the feeding roller 5 rotate in synchronization with each other. , The above-mentioned banknotes X ... are sequentially output.

The illustrated embodiment is configured as described above, and the operation will be described below. When the pickup roller 4 and the feeding roller 5 described above are cyclically rotated in the arrow direction (feeding direction) of FIG. 1, a conveying force is applied to the uppermost one banknote X of the banknote storage unit 2, and the banknote X is transferred. After passing between the feeding roller 5 and the gate roller 7 described above, the pair of upper and lower conveying rollers 8 and 8 sandwich and convey them in the direction of the imaginary line arrow in FIG.

When the above-mentioned bill X passes between the feeding roller 5 and the gate roller 7, the gate roller 7 moves from the normal position of a predetermined overlap shown by a virtual line in FIG. 2 to a small overlap shown by a solid line in FIG. Retraction in the lap direction is allowed.

Since the gate roller 7 is arranged in the recessed portion 6 for overlapping in this way, the gate roller 7 is less worn and the durability can be improved. Since the gate roller 7 is allowed to move backward by the variable overlap machine 9, no high precision is required for the overlap amount of the gate roller 7 with respect to the feeding roller 5, and the adjustment at the time of assembly is easy. There is an effect.

In the correspondence between the configuration of the present invention and the above-described embodiment, the paper sheet feeding device of the present invention corresponds to the bill feeding device of the embodiment, and similarly, the paper sheet is changed to the bill X. Correspondingly, the paper sheet storage unit corresponds to the banknote storage unit 2, but the invention is not limited to the configuration of the above-described embodiment. For example, the configuration described above outputs one plain paper sheet. Of course, it may be applied to a copying machine or other sheet feeding device.
