BALL POLISHING DEVICE FOR GAME MACHINE

PROBLEM TO BE SOLVED: To provide a ball polishing device for game machines of a type incorporated in a game machine capable of exerting an excellent cleaning function without impairing a degree of design freedom in the game machine.SOLUTION: A ball polishing device 1A includes: a ball conveyance path 10 for linearly conveying Pachinko balls 100; a motor-drive type spiral conveyance shaft 30 that is formed by forming a spiral ball feed groove 300 around an outer peripheral surface of a columnar member, in which rotary axial lines are parallel disposed along the ball conveyance path 10, and that conveys the Pachinko balls 100 in the ball conveyance path 10; and a cleaning member 4A disposed at a mid-flow of the ball conveyance path 10 to expose a cleaning surface 41 with which the Pachinko balls 100 come into contact. The ball conveyance path 10 is vertically disposed so as to vertically convey, by the turning of the spiral conveyance shaft 30, the Pachinko balls 100 entering the ball conveyance path 10 and having parts thereof buried in the ball feed groove 300, and clean them, with their sliding on the cleaning surface 41. 【課題】遊技機に内装する方式の遊技機用球磨き装置について、遊技機における設計の自由度を損なうことなく優れたクリーニング機能を発揮可能とする。【解決手段】パチンコ球１００を直線的に搬送する球搬送路１０と、円柱部材の外周面に螺旋状の球送り溝３００が形成されてなりその回転軸線が球搬送路１０に沿うように並列配置されて球搬送路１０のパチンコ球１００を搬送するモータ駆動式のスパイラル搬送軸３０と、球搬送路１０の途中でパチンコ球１００が接するクリーニング面４１を露出して配置されたクリーニング部材４Ａとを備えた球磨き装置１Ａであって、その球搬送路１０を縦向きの配置として、球搬送路１０に入りその一部を球送り溝３００に没入したパチンコ球１００を、スパイラル搬送軸３０の回動で縦方向に搬送しながらクリーニング面４１上で摺動させてクリーニングを行うものとした。【選択図】図３
