Next, the impact absorption operation at the time of coin insertion in the structure of the coin insertion passage configured as described above will be described. The coin A inserted from the coin insertion slot 3 falls directly below the coin passage 42 substantially along the center line C of the coin insertion slot 3 and collides with the collision point 52 of the shock absorbing plate 11. At the collision point 52, the falling energy f of the coin A is applied to the shock absorbing plate 11 as an external force, and this external force f is divided into a component force f _A perpendicular to the slope and a component force f _B along the slope. . At this time, if the direction of the component force f _A is on the right side of the boundary point 51 between the lower end face 47 of the shock absorbing plate 11 and the notch 48 in FIG. A clockwise moment is generated in the plate 11, the shock absorbing plate 11 rotates clockwise by the height of the notch 48, and absorbs the drop impact of the coin A, so that the coin A does not bounce and , The rolling speed is sufficiently slowed down and the coin is guided to the coin sorting unit 13.

In this embodiment, the inclination angle of the inclined surface 11 a of the shock absorbing plate 11 and the size of the notch 47 are appropriately selected so that the direction of the component force f _A comes to the right of the boundary point 51. Further, since the screw 50 is inserted in the insertion hole 46 with a play, when the coin A collides with the impact absorbing plate 11, the impact absorbing plate 11 rattles due to the play, which also causes the play. The coin A is prevented from bouncing and the rolling speed is slowed down.
