The belts 41, 51, 61 are slightly inclined in such a way that the downstream side approaches the passage side plate 13.

The support shaft 44 is driven to rotate by a motor (not shown), and each of the belts 41, 51, 61 is driven to rotate.

Next, the operation of this embodiment will be described.

As an example of the dimensional relationship between the coin to be processed and each part, the thickness of the coin to be processed is 1.3 to 2.8 m.
m, diameter is 18 ~ 31mm, height H1 is 3mm, H2 is 0.8mm, H3
Is 0.1 mm, H4 is 0.2 mm, and the thickness T of the passage bottom plates 21 and 22 is
It should be about 0.7 mm.

When the rotating disk 1 is driven to rotate in the direction of the arrow in the figure, the coins supplied on the rotating disk 1 rotate together with the rotating disk 1 and the centrifugal force caused by the rotation of the rotating disk 1 causes the coins to rotate. It moves to the peripheral edge of the rotating disk 1 and moves along the inner surface of the peripheral wall 3.

Some of the coins on the rotating disk 1 (coins in contact with the rotating disk 1 and the minimum thickness coin in a two-ply state) pass under the thickness regulating member 5 and move toward the coin passage 12.

Then, the thickness direction 1 is set under the thickness regulating member 5.
The coins passed in the sheet state move along the guide wall 18 of the guide plate 17 and are held under the rotatably driven coin transfer belt 41, and are moved in the direction of the coin passage 12 by the coin transfer belt 41. It is forcibly transferred to. for that reason,
The coin moves from the guide wall 18 of the guide plate 17 to the reference passage wall 15 of the passage side plate 13, one edge of the coin is lifted on the coin introduction surface portion 23, and further, the entire coin is placed on the passage bottom plate 21. On

The coins placed on the passage bottom plate 21 move along the reference passage wall 15 while being held under the coin transfer belt 41 and the coin transfer belt 51, and are identified by the identification unit 31. Then, the coin is conveyed in the coin passage 12 while being held below the coin conveying belt 61.

For example, when the discriminating section 31 identifies a coin to be eliminated such as a counterfeit coin, the coin next to the coin is locked by the stopper 34 and the shutter of the sorting hole 36 is opened. Then, the coin is removed from the sorting hole 36.

Among the coins that have passed under the thickness regulating member 5 in the thickness direction, one coin whose one side edge has not been lifted on the coin introduction surface portion 23 contacts the regulation wall portion 24. The entry into the coin passage 12 is regulated, and the coin is returned onto the rotating disk 1 along the regulating wall 24 by the rotating force of the rotating disk 1.

When two coins of the minimum thickness pass under the thickness regulating member 5 in a state of being overlapped and are held under the coin transport belt 41, the upper coin in the overlapped state is moved by the coin transport belt 41 to the coin passage. While the coin is moved in the direction of 12, the lower coin in the overlapped state is moved in the rotating direction because friction occurs in contact with the rotating disk 1. As a result, the upper coin and the lower coin in the overlapping state are displaced and overlap with each other, and the upper coin is lifted on the coin introduction surface portion 23, but the lower coin is abutted by the regulating wall portion 24 and rotated. It is returned to disk 1. Therefore, only the upper coin in the overlapping state is sent to the coin passage 12.

Since the floating of the coin transfer belt 41 at a position above the regulating wall portion 24 is restricted to a minimum, when coins are fed into the coin passage 12 through the coin introduction surface portion 23, the coin transfer belt 41 is By ascending, it is possible to restrict another coin from entering the coin passage 12.

A pulley on the starting end side of the coin transfer belt 51
Since the lower surface engaging with 53 is located above the rotating disk 1, it is possible to prevent coins from jumping up on the rotating disk 1 and entering the coin passage 12 over the regulating wall 24. it can.

[0041]

According to the first aspect of the present invention, of the coins transferred to the entrance of the coin passage by the coin transfer belt, the coins moving along the reference passage wall are inserted into the coin passage through the coin introduction surface. In addition, coins that are not loaded on the coin introduction surface portion such as coins adjacent to the coin moving along the reference passage wall in the passage width direction with the coin moving along the reference passage wall can be returned to the rotating disk by being regulated by the regulation wall portion. Therefore, coin jamming at the entrance of the coin passage can be prevented, and only coins transferred by the coin transfer belt through the coin introduction surface can be reliably fed into the coin passage one by one.

According to the second aspect of the present invention, in the first aspect of the present invention, the floating of the coin transfer belt at a position above the regulating wall portion is regulated, and when the coin is fed into the coin passage through the coin introduction surface portion. In addition, it is possible to restrict another coin from entering the coin passage by floating the coin transfer belt. Therefore, only coins transferred by the coin transfer belt through the coin introduction surface portion can be more reliably fed into the coin passage one by one.

According to the third aspect of the present invention, in the first aspect of the present invention, even when the thickness difference between the coins to be processed is twice or more, two coins of the minimum thickness coin overlap under the thickness regulating member. If the coin passes through and is held under the coin transfer belt, the upper coin in the overlap state is moved toward the coin passage by the coin transfer belt, whereas the lower coin in the overlap state is in contact with the rotating disk. Because the friction is caused to move in the rotating direction, the upper coin and the lower coin in the overlapping state are displaced and overlapped, and the upper coin is taken into the coin passage through the coin introduction surface portion, The coin on the side can be regulated by the regulating wall and returned to the rotating disk. Therefore, only the upper coins in the overlapping state can be reliably sent one by one into the coin passage.
