PROBLEM TO BE SOLVED: To quickly supply coins while enhancing polishing force by providing forcible coin supplying mechanism which presses the upper surface or the lower surface of the coin to a coin introducing part so as to push it and a coin guide which strongly presses a coin polishing surface on a coin surface with the both end parts of the coin left. SOLUTION: Host of the coins C are thown from a coin throwing chute 5 so as to fall on the rotary board 3a of a coin one-line supply device, discharged from a discharge port provided in an outer peripheral frame 3b and supplied in a one-line state. Then, the coins C are held between vertical driving rollers 2b and 2c in the introducing part of the grinding part and made to progress forwards forcibly. Then, the coins C are inserted to a pair of grinding cloths 1a and 1b and the both upper and lower surfaces are ground by the running grinding cloths 1a and 1b. The grinding cloths 1a and 1b are contained in the containing grooves of upper and lower guide blocks 1e, the coins C are pressed between the both grinding cloths 1a and 1b so that stain is removed by forcible rubbing. |
