[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a banknote insertion / return device in which a banknote insertion / return port and a return-only port are arranged on a front surface facing a user in a vending machine for selling high-value products. ..

[0002]

2. Description of the Related Art For example, a bill inserting / returning device shown in FIG. 2 which is applied to a conventional vending machine of this type is shown in FIG.
An insertion-only opening 103 and a return-only opening 105 are arranged in a vertical positional relationship on the front surface 102 of the apparatus main body 101 facing the user, and a transport path extending from the upper insertion-only opening 103 into the inside of the apparatus is from the lower return-only opening 105. A transport path a is formed in communication with the transport path extending inward. Insertion port 103
The banknote identifying unit 107 arranged in the vicinity is for identifying the authenticity and denomination of the inserted banknote, and the genuine banknotes among the banknotes that have passed through the identifying unit 107 are the genuine banknote transport path b branched from the transport path a. Stocker 109 for storing banknotes
Be transported to. Fake banknotes, sheet materials other than banknotes, banknotes having different denominations (hereinafter referred to as fake banknotes, etc.) are returned to the user through the return path 105 through the transportation path a. The banknote transport path a is composed of a pair of endless belts (not shown), and is often nipped and transported in a region where a part of both belts are in contact travel.

By the way, in such an apparatus, a banknote insertion port 103 and a banknote return port 105 are often arranged on the front surface 102 of the apparatus main body 101 in order to be provided for the user's convenience. The reversal section a1 is necessarily formed on the transport path a, and even if the bill is determined to be a false banknote by the identifying unit 107, the false banknote is a false banknote.
Pass the full length of. Therefore, if a relatively hard resin or a foreign material such as a metal plate is intentionally or mistakenly inserted from the insertion-specific opening 103, this portion is easily damaged when the metal plate or the like passes through the inversion part a1. Further, since the insertion-only port 103 and the return-only port 105 are vertically separated from each other, it is difficult for the user to notice the returned banknote. In particular, even if a banknote with a different denomination is inserted due to an error and the banknote is returned, if the user does not notice the returned banknote, the desired product may not be discharged even if the purchase button is pressed, causing unnecessary complaints. Expected to do.

On the other hand, as shown in FIG. 3, the discriminating section 107 is constituted by using the insertion-dedicated port 103 in FIG. 2 as the insertion / return port 111 and allowing the endless belt constituting the transport path a to be rotated forward and backward. The above-mentioned problem can be solved if the fake bill identified in step 2 is configured to be sent back and immediately returned to the user through the insertion / return port 111. or,
The insertion / return device of this figure has another conveyance path c that is branched at the intermediate portion a2 of the conveyance path a and is arranged toward the stocker 109, and the other conveyance path c is inserted from the insertion / return port 111. There is a temporary holding unit 113 that temporarily holds the accumulated banknotes until a predetermined number of banknotes are stored, and the banknotes held in the temporary holding unit 113 are collectively conveyed to the stocker 109 or the purchase intention of the user is changed. In case of return, it will be exclusively returned 10
It is configured to return from 5.

However, in the device as described above, when the false bill 115 having the fold 115a as shown in FIG. 4 is inserted from the insertion / return port 111 at the rear end portion in the insertion direction, the false bill 115 is inserted. When the paper is fed backward, the end having the fold 115a is used as the leading end and is conveyed toward the return-only port 105, so that a jam is likely to occur. If a jam occurs when returning fake bills, it is necessary to stop the operation of the device to remove the jammed paper, and if it takes time to remove it, it will hinder the use of subsequent users and reduce the efficiency of use of the device. There was a problem. Generally, when inserting a banknote having a crease as described above from an insertion opening of a vending machine or the like, it is usual to insert it from the tip having no crease in consideration of ease of insertion, Such a problem is likely to occur.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the related art. When a false paper sheet is inserted, it is immediately returned to destroy the paper sheet conveyance path. In addition, even if a false paper sheet having a crease is inserted and a jam occurs when returning the false paper sheet, the jam paper sheet is reliably returned without stopping the device. The purpose of the present invention is to provide a paper sheet inserting / returning device.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has the following configuration.

That is, when the authenticity discriminating unit arranged near the insertion / return port determines that the inserted paper sheet is true, the paper sheet is conveyed toward the inside, and the paper is determined to be false. Even if the leaf is returned from the insertion / return port and the identification unit is determined to be false, if the fake paper sheet returned from the insertion / return port causes a jam, the jam paper sheet Is configured to be returned from the return-only outlet.

With this configuration, when the user inserts the fake bill, the fake bill is immediately returned from the insertion / return port 3 so that the reversal portion A1a of the first transport path A is not destroyed. Further, since the return route (the route from the identification unit 9 to the insertion / return port 3) is short, it is possible to return the fake bill in a short time, and the bill is returned because the insertion port and the return port are combined. It is easy for users to understand. Then, even if a jam occurs when returning the counterfeit banknote when the counterfeit banknote having a folding tendency as shown in FIG. 4 is inserted, the jammed counterfeit banknote is not stopped without using the vending machine. Since it can be surely returned from the return-only port 5, it does not reduce the utilization efficiency of the vending machine without the trouble of removing the jammed paper.

Further, the present invention can be similarly applied to a device for handling banknotes other than an automatic vending machine, such as a banknote payout device or a banknote receiving device. It can also be applied to a device that handles tickets and the like.

In addition, in the claims, the pseudo paper sheet is
The concept is not limited to fake banknotes, but includes genuine banknotes and the like that have different denominations and sheet-like objects other than banknotes.
