For this reason, there has been a problem that fraud such as pushing a foreign substance such as a sponge into the coin return port is carried out and the change is stolen from the coin return port. Therefore, as a coin return port capable of preventing such an erroneous operation, for example, a coin return port having a structure provided with a sharpened piece 71 which is inclined and inclined downward to the coin return route 70 according to Japanese Utility Model Publication No. 62-17901. It was invented. 72 is a main body of a coin for returning coins such as public telephones, 73 is a coin receiving opening, 74 is an outlet,
Reference numeral 75 is an opening / closing plate, 76 is a receiving portion, 77 is a protruding piece, and 78 is a protrusion.

In Japanese Utility Model Laid-Open No. 1-91972, a plate 84 is provided in a gap 83 formed by a coin pop-out prevention plate 81 and a coin return path 82, and the plate 84 and the coin pop-out prevention plate 81 are provided. Abutting against and returning coins 82
There has also been devised a coin return port having a structure that closes the door to prevent foreign matter from being inserted through the coin outlet 85.

[0004]

In such a conventional coin return port, there is a gap between the projecting piece and the opening / closing plate when the opening / closing plate is slightly pushed, and a foreign substance can be pushed in. In addition, in order to make the gap small and make it difficult for foreign matter to enter, it is sufficient to lengthen the protruding piece, but if the protruding piece is lengthened, it may hinder the fall of returned coins and cause a jam of coins. there were.

Further, although it is effective against foreign substances such as balloons that rupture upon contact with sharpened pieces, it can be compressed and deformed like a sponge, and has no sufficient invasion prevention effect against the intrusion of foreign substances that do not rupture. .

Further, as in Japanese Utility Model Application Laid-Open No. 1-91972, the plate body and the coin pop-out prevention plate are in contact with each other to close the coin return path and prevent the insertion of foreign matter from the coin return port. However, there is also a problem that it is difficult to take out the returned coins because the coin pop-out prevention plate can be opened only to the position where it comes into contact with the plate body.

The present invention has been made in view of the above circumstances. Even when the opening / closing plate is in a half-open state, the gap can be narrowed to make it difficult for foreign matter to enter, and to facilitate the taking out of returned coins. It is intended to provide a structure for preventing foreign matter insertion at a return port.
