Abstract

PROBLEM TO BE SOLVED: To prevent meandering a lifting/sending belt, and smoothly rotate it by forming recessed-projecting guiding parts on the reverse of the lifting/ ending belt, and forming a guide part coincident with the guiding parts in at least one of an upper roller and a lower roller. SOLUTION: In a raising-lowering type polishing device, a large number of game balls Y flowing down from an inlet, press a guiding member in the downward direction by flowing in between the guiding member and a lower roller 6, but rise while slidingly rotating by a flexible material 15 having low frictional resistance while being sandwiched one by one between it and the lower roller 6 by elastic repulsive force of an elastic body. Similarly, they are carried while slidingly rotating with the flexible material 15 even on a rising surface of a lifting/sending bnelt 10, and are discharged from a discharge port by being polished. In the lifting/sending belt 10, for example, three-strip recessed-projecting guiding parts 10a are formed on the reverse of it. A guide part 6b coincident with the guiding parts 10a is formed on an outer periphery of the lower roller 6. Therefore, the lifting/sending belt 10 can smoothly rotate since meandering is prevented.
