When abutting on itself in a state of projecting rearward from the rear end of the upper side stretched portion 12a, the conveyance of the coin K is regulated regardless of the displacement of the deposit belt 12, and the separation belt 172 is rotated to cause the separation belt 172 to rotate. By being displaced along the extending direction, the separating pin 173 presses the leading coin K that abuts against the stopper 174 to separate it from other coins K, and the separated coin K is gradually moved downward toward the rear. Since it is supplied by sandwiching it with the auxiliary conveyor belt 182 inclined to the front, the time required for separating the coin K is shortened as compared with the case of passing through the coin passage hole of the rotating body as in the related art. Can be planned.

Moreover, conventionally, the coins conveyed in the deposit unit are stacked in the coin storage portion so that they are not overlapped with each other, so that the coins that have not been overlapped with each other are overlapped in the coin storage portion. In the above coin separating device 10, the leading coin K among the coins K conveyed so as not to overlap each other by the depositing unit 10a is separated from the other coins K and supplied. Therefore, there is no waste in the form of carrying the coin K, and the shortening of the carrying time is more remarkable.

Further, according to the coin separating device 10, since the displacement of the separating belt 172 and the displacement of the auxiliary conveying belt 182 are synchronized with the displacement of the conveying member 23 of the coin checking device 20, the coins separated and supplied. The K can be delivered and received smoothly, and the transfer time can be shortened.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

The guide mechanism unit 16 is provided in the above-described embodiment, but in the present invention, the guide mechanism may not be provided as long as the posture of the coin conveyed by the depositing unit can be maintained.
