The medal 14 placed on the medal placement unit 42 is prevented from dropping from the medal placement unit 42 by the turn-back unit 43.

  Note that when the medal 14 is discharged from the discharge port 45, the cleaning drum 32 temporarily lifts the medal 14 upward using the discharge engaging claws 41 because the cleaning liquid is stored in the cleaning tank 35. This is because it is considered.

  The cleaned medal 14a discharged from the discharge port 45 (see FIG. 6), that is, the medal 14a inserted into the dewatering chute 61 is sequentially placed on the belt 65 of the dewatering conveyor mechanism 62, and above the belt 65. Be transported. The medal 14a is transferred to the dewatering roller mechanism 63 by the belt 65, and passes between the dewatering rollers 67a and 67b and 68a and 68b of the dewatering roller mechanism 63.

  And the medal 14b from which the adhering water | moisture content was wiped off by the spin-drying | dehydration rollers 67a and 67b, 68a and 68b is sequentially carried out to the carry-out chute 73. Further, the medal 14b carried out on the carry-out chute 73 is placed on the belt 74 of the medal discharge unit 70 via the chute 73, and is conveyed by the belt 74 to be outside the machine, for example, the game medium cleaning device 10.
