Description

  The present invention relates to a medal drying apparatus that dries the water adhering to a medal after washing with water in order to reuse the medal used in a gaming machine such as a slot machine.

  Conventionally, in order to hygienically reuse medals used in gaming machines such as slot machines, medals sent from the collection line of gaming machines are transported to a medal cleaning device, and medals washed with this medal cleaning device are washed away. A medal drying device designed to dry is used.

  As a technique related to such a medal drying device, a “water absorption device” described in Patent Document 1 is provided around a hollow pipe 42 rotatably provided at both ends of a handle 41 as shown in FIG. A water-absorbing roller 44 around which the water-absorbing material 43 is wound is formed, and the hollow pipe 42 of the water-absorbing roller 44 has a plurality of small holes 45, 45..., While the hollow pipe 42 is vacuumed through a rubber pipe 46. In the water absorption operation, water absorption is always performed through the small holes 45, 45... Of the hollow pipe 42. A device 47 is required.

Further, as shown in FIG. 8, the “cleaning apparatus” described in Patent Document 2 includes a cleaning unit having a pair of water-absorbing rollers 51 to 54 that are in pressure contact with each other, and a draining roller that is in pressure-contact with one of the water-absorbing rollers 52 and 54. In this example, the wet medals are sandwiched between the pair of water-absorbing rollers 51 and 52 and the water-absorbing rollers 53 and 54, and the moisture is absorbed and dried. In such a configuration, a structure in which moisture contained in the water absorbing rollers 52 and 54 is sucked by the draining rollers 55 and 56 is required. Further, since each of the water absorption rollers 51 to 54 is formed by covering the outer periphery with a soft porous elastic member such as sponge rubber or felt fiber, dirt that could not be removed in the cleaning process adheres to the water absorption roller. As a result, the water-absorbing roller is soiled, and the water-absorbing roller needs to be frequently replaced because the water-absorbing roller rots with water adhering to it and causes a bad odor.
