Abstract

PROBLEM TO BE SOLVED: To prevent the conveyance delay and state change of paper sheets without lowering a lead-in force in leading the paper sheets into a reverse conveying path by providing one or more auxiliary conveying means in addition to two support parts for supplying conveying force. SOLUTION: Two parts of a paper sheet are supported by two belts 4a, 4b to convey the paper sheet. In order to change a paper sheet conveying direction in a first conveying path to guide the paper sheet to a third conveying path, brush rollers 3a-3d need to press the paper sheet to carrier rubber rollers 8b, 8a opposed to the belts 4a, 4b. In this case, an auxiliary rubber roller 9 is installed to have the same action as the case of supporting the paper sheet in three parts while supporting the paper sheet in two parts. The paper sheet can therefore be stably conveyed while having the effect of reducing conveying resistance and reducing damage of a bill caused by deformation.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet handling apparatus, and more particularly, to a sheet sorting apparatus capable of sorting sheets such as banknotes and forms.

[0002]

2. Description of the Related Art As a paper sheet reversing device for reversing the front and back of a paper sheet, there is one described in Japanese Patent Application Laid-Open No. 8-20466. In this paper sheet reversing device, the conveyance path is configured to support and convey paper sheets by three belts. Also, according to the result of the determination of the front and back, the paper sheet is sorted into the conveyance path into the front paper sheet and the back paper sheet using the blade.

[0003] A first transport path for transporting front sheets and a second transport path for transporting and reversing reverse sheets are joined at a junction to be transported to a downstream transport path. It has become.
Further, in the second transport path, the reversing time is adjusted by changing the reversing speed of the paper sheet, and the transport time of the inverted paper sheet is adjusted.

[0004]

However, the mechanism for changing the reversing speed is complicated in the above-described conventional conveying path, and an increase in cost is inevitable. Further, in the above-mentioned conventional example, paper sheets are placed in three places (for example, three
The belt is transported while supported by three belts, but the number of components required to support it in three places is greater than the transport path that supports paper sheets in two places, and costs are higher. It is inevitable that it will be high.

On the other hand, even if the configuration for supporting the paper sheets in the transport path is simply changed from three locations to two locations, the reversal transport force is reduced when the paper sheets are pulled into the reverse transport path. There is a possibility that the conveyance of the paper sheets guided to the road may be delayed.

[0006]

Therefore, according to the present invention, a transport path for supporting paper sheets at two locations is provided by providing one or more auxiliary transport means in addition to two support portions for providing a transport force. In this case, no delay in sheet conveyance or a change in state occurs without reducing the drawing force when the sheets are drawn into the reverse conveyance path.
