And is inserted between the coin supporting surface 11 and the tip end portion 22a of the lip member 22 of the rotating member 20. When the coin C is conveyed by the delivery belt 401, the coin C tries to jump due to the rotational force of the delivery belt 401 rotating at high speed, mechanical vibration, etc., but the coin jump prevention plate 402 is located above the delivery belt 401. Is provided, the bouncing of the coin C is suppressed, and the coin C is transported without coming off the delivery belt 401.

As described above, when the coin C is conveyed from the coin outlet 8 to the coin sorting passage 10, the coin C is carried on the delivery belt 401. Therefore, the coin C passes through the coin delivery passage 13
Is not pressed against the course plate 9 constituting the above, and the coin pressing force also does not act on the delivery belt 401, so that abrasion of the course plate 9, the delivery belt 401 and the coin C is suppressed. Moreover, since it is sufficient to apply only the driving force for carrying the coin C to the delivery belt 401, the driving force of the motor 5 that drives the delivery belt 401 can be reduced. Further, since the coin C is not always pressed by the delivery belt 401 with a constant force, the pulley 4 that stretches the delivery belt 401 is used.
03, 404, 405 can be fixed, each of these pulleys 403,
A mechanism for vertically moving 404 and 405 can be omitted.

The coin C that has moved to the coin sorting passage 10 moves in the circumferential direction while being pressed against the guide wall 12 and the coin support surface 11 by the lip member 22 of the rotating member 20. While the coin C moves along the guide wall 12 in this manner, various coins C having different diameters correspond to the coin drop ports 15a.
It falls to ~ 15b and is classified.

In addition, in the said Example, although the case where it applied to a coin sorter was shown, you may apply to other coin processing machines, for example, a coin counter.
