However, in the conventional coin sorting apparatus described above, the coins are supported and sorted by the flapper 28 and the substrate 21 which is a separate member from the flapper 28 at three points. So the flapper 28
There is a problem that the positional deviation between the substrate 21 and the substrate 21 directly affects the sorting accuracy, and thus the sorting accuracy is not stable. Further, when the adjustment is performed to stabilize the sorting accuracy, since the diameter and the thickness are simultaneously sorted by the support at the three points, the coin rail 27 can be finely moved up and down for adjustment. , The diameter and the thickness must be adjusted at the same time, which requires skill in the adjustment work.
It has the drawback of being complicated and time consuming.

Therefore, the present invention has been made in view of the above problems or drawbacks of the prior art, and an object of the present invention is to provide a coin sorting device which stabilizes sorting accuracy and does not require adjustment. It is in.
