<P>PROBLEM TO BE SOLVED: To provide a Pachinko ball polishing and lifting apparatus improved in replacement work efficiency by making only an anti-backing plate replaceable with a belt conveying mechanism or the like unchanged. <P>SOLUTION: A plurality of anti-backing plates 67 each with one side edge located facing the outer peripheral surface of a driving pulley 7 and recessed in circular arc shape are juxtaposed in an ejection guide 68. Each anti-backing plate 67 is supported at its lower part by a horizontal supporting shaft 77 disposed inside the ejection guide 68 so as to be parallel with a rotating shaft 6 of the driving pulley 7, and turns with the supporting shaft 77 as a fulcrum while being always urged to turn to the driving pulley 7 side by resilient means 79. The lower edge of each anti-backing plate 67 is provided with a recessed groove 76 detachably fitted to the supporting shaft 77 so that each anti-backing plate 67 can be attached to or detached from the supporting shaft 77 from a direction orthogonal to the supporting shaft 77. <P>COPYRIGHT: (C)2012,JPO&INPIT |
