PROBLEM TO BE SOLVED: To prevent the wear of a pair of carrying rollers on which a large load is imposed. SOLUTION: A pair of carrying rollers 47a is formed of a metal, and the outer peripheral surfaces of the rollers 47a are knurled. The pair of carrying rollers 47a holds a 1st slide mount 17d being fed out from a mount feed-out port 39 in between. Since a multiple feed prevention plate 40 comes into contact with the mount 17d being fed out, the large load is imposed on the pair of carrying rollers 47a. However, the respective rollers 47a are formed of the metal, so that their outer peripheries can be prevented from being worn due to friction with the mount 17. Then, the respective rollers 47a can be prevented from sliding on the mount 17d because their outer peripheral surfaces are knurled.
