PROBLEM TO BE SOLVED: To maintain a medal always pure and to unnecessitate medal carrying operation for grinding without using a large-scale and expensive grinder. SOLUTION: At a medal recovering conveyer 27 carrying a medal overflowing from plural game devices to a recovery box, a purifying means 13 for removing dust and fat stuck to the surface of a medal is provided closely to the carrying, path of a conveyer 11 or between the carrying path terminal and the recovering box of the conveyer 11. The means 13 is constituted of a flexible partition board 15 partitioning a carrying space over the conveyer, e.g. into a small space 21, a rotary brush 17 arranged within the small space to be rotate-driven to be in contact with a medal 12 under carrying, and a dust collector 19 sucking air within the small space to collect dust and fat separated from the medal 12. |
