Description

The present invention relates to a coin receiving device used for an automatic ticket vending machine, for example.

(B) Conventional technology Conventionally, as the coin receiving device of the above-described example, there is a device having a structure in which coins are inserted one by one into a coin insertion slot set to a predetermined coin width.

However, such a coin receiving apparatus has a drawback that when a large number of coins are inserted, the coin insertion time becomes long.

In order to solve such a defect, conventionally, for example, ninth
A coin receiving device of a batch input type as shown in the figure has already been invented.

In other words, a coin slot 91 having a wide mouth through which a plurality of coins A can be inserted at the same time is provided.
A coin storage portion 94 is constituted by a fixed guide 92 and a leaf spring 93 opposed to the fixed guide 92 below the fixed guide 92, and the tip 93a of the above-mentioned leaf spring 93 is directed inside the fixed guide 92 in the falling direction of the coin A. Part of the tip 93a
A driving pulley 97 fixed to the rotating shaft of a motor 96 while forming a single-sheet feeding portion 95 of the coin A between the
A belt-type coin receiving device in which a belt 99 is stretched between the driven pulley 98 and a friction roller 100 that rotates coaxially with the driven pulley 98 in a direction opposite to the falling direction of the coin A is provided. Device.

In the coin receiving apparatus shown in FIG. 9, a large number of coins A can be inserted at once from the above-mentioned coin insertion port 91.
Since one sheet is sequentially taken out by the action of the roller 95 and the so-called reverse roller, there is an advantage that even if the number of coins to be inserted is large, the coin insertion time can be greatly reduced.

(C) Problems to be Solved by the Invention However, in such a coin-receiving type coin receiving apparatus, since the opening area of the coin input port 91 is large, the coin A is deliberately or inadvertently inserted from the coin input port 91. In addition, there is a case where a foreign substance is thrown in, and this foreign substance is clogged in the above-mentioned single sheet feeding section 95, so that there is a problem that the apparatus cannot be operated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a coin receiving apparatus capable of reliably removing foreign matter inserted from a coin insertion slot and sequentially taking out and accepting only one inserted coin.

(D) Means for Solving the Problems The present invention is a coin receiving device that accepts a plurality of coins inserted while permitting batch input, rolls the coins downward in a tilted direction, and outputs one coin. A coin slot into which a plurality of coins can be inserted at the same time, and a coin provided at the lower part of the coin slot to roll the inserted coin downward and to allow the passage itself to be opened to remove foreign matter. A passage, a coin ejecting means disposed at an outlet of the coin passage, a foreign matter detecting means for detecting foreign matter insertion into the coin passage, and a coin ejecting means based on an output of the foreign matter detecting means. And a foreign matter removing means for opening the coin passage itself located in front of the coin receiving device.

According to the present invention, when a foreign object is intentionally or inadvertently inserted from the above-described coin insertion slot, the foreign object is detected by the foreign object detection unit in the coin passage in front of the single coin ejection unit, Based on the output of the foreign matter detecting means, the above foreign matter removing means opens the coin passage itself and removes foreign matter or coins containing foreign matter.

(F) Advantages of the Invention For this reason, it is possible to immediately and surely remove the foreign matter from the above-described open coin passage before the foreign matter inserted from the coin insertion slot is supplied to the coin one sheet feeding means. Therefore, it is possible to prevent the foreign matter from being packed in the one-coin unloading means, and to prevent the inoperability of the apparatus due to the foreign matter input.

On the other hand, since the inserted coins in the normal state are sequentially output one by one by the above-described coin one-sheet output means, there is an effect that only the input coins can be accepted.

When coins and foreign matter are inserted at the same time, these coins and foreign matter are sent back to, for example, a receiving tray from an open coin passage.
