发明名称 PACHINKO BALL GUIDE GUTTER
摘要 PROBLEM TO BE SOLVED: To provide a pachinko ball guide gutter in which dust clinging to balls and foreign objects entering a ball flow passage, such as screws, nails, and fragments of wiring can surely be removed while rolling the balls at high speed, without requiring large space. SOLUTION: A plurality of inclined passages 7, 8 having openings 12 on both sides of a guide 13 supporting the center of the bottom face of each ball are formed between vertical partition walls 4, 4 while being inclined in alternate opposite directions and a folding part 14 is formed between the inclined passages. The folding part 14 supports the outside of each ball by use of only arcuate curved guides 15 and is provided with a curved opening 16 on each side, and dust clinging to the balls and foreign objects entering a ball flow passage drop from the openings 12 and the curved openings 16. This pachinko ball guide gutter can be made smaller than those of the prior art, and since the guides 13 and the curved guides 15 support the center of the bottom face of each ball, the balls do not sink as do in conventional systems and therefore the rolling speed of the balls does not decreased.
