Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a coin accepting device used, for example, in an automatic ticket vending machine.

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

However, such a coin receiving device has a drawback that it takes a long time to insert coins when a large number of coins are inserted.

In order to solve these drawbacks, for example, a batch-loading type coin receiving device as shown in FIG. 7 has already been invented.

That is, a coin input lower 1 with a wide opening that can simultaneously input a plurality of coins A is provided, and below the coin input lower 1, a fixed guide 72 and a leaf spring 73 facing the fixed guide 72 are provided. The tip 73a of the leaf spring 73 is tilted toward the falling direction of the coin A and approaches the inner side of the fixed guide 72, so that a space between the tip 73a and the fixed guide 72 is formed. A single coin A ejecting part 75 is formed in the area, and a belt 8o is stretched between a driving pulley 78 fitted to a rotating shaft 77 of a motor 76 and a driven pulley 79.
9 and a friction roller 82 which rotates in the opposite direction to the falling direction of the coins A is provided on the same axis 81. This is a batch-loading type coin receiving device.

In the coin receiving device shown in FIG. 7, a large number of coins A can be thrown in at once from the coin insertion lower 1, and the large number of coins A thrown in at once can be replaced by one coin. Since the coins are sequentially dispensed by the action of the dispensing section 75 and the friction roller 82, which is a so-called reversing roller, there is an advantage that even when a large number of coins are inserted, the coin input time can be significantly shortened.

(c) Problems to be Solved by the Invention However, since the opening area of the coin input lower 1 is large in such a bulk input type coin receiving device, coins may be intentionally or inadvertently removed from the coin input lower 1. In addition to A, foreign matter may be thrown in, and this foreign matter may clog the single sheet dispensing section 75, causing the apparatus to become inoperable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin receiving device that can reliably remove foreign objects thrown in from a coin slot and sequentially eject and accept only the inserted coins.

(d) Means for Solving the Problems This invention provides a coin slot into which a plurality of coins can be inserted at the same time, a coin passage provided below the coin slot,
a disk for dispensing a single coin, which is disposed at an exit portion of the coin passage and has a plurality of dogs formed at predetermined intervals; an opening/closing plate disposed at a transfer portion between the outlet portion and the disk; The coin receiving device is characterized by being equipped with a foreign object detecting means for detecting a foreign object thrown into the coin passage, and a foreign object removing means for opening the coin passage and the opening/closing plate based on the output of the foreign object detecting means. .

(E) Effect According to the present invention, when a foreign object is intentionally or inadvertently thrown into the coin slot, the foreign object is detected by the foreign object detection means, and based on the output of the foreign object detection means, the foreign object is detected. A removal means opens the coin passage and the opening/closing plate.

(F) Effects of the Invention Therefore, foreign objects inserted from the coin input port can be reliably removed from the open coin passage and the opening/closing plate, thereby preventing the device from becoming inoperable due to the introduction of foreign objects. There is an effect that can be prevented.

On the other hand, since the inserted coins during normal operation are sequentially dispensed by the above-mentioned coin dispensing disk, there is an effect that only the inserted coins can be accepted.
