PACHINKO BALL RECOVERY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a ball recovery device which enables the smooth discharge of pachinko balls from a ball discharge part while guiding the large number of pachinko balls stopped by a ball receiving part to the ball discharge part wherever the pachinko balls to the ball receiving part drop. SOLUTION: A chamfered part 22 is formed at a corner part 21 which is formed on the inside plane of the link part between the outer circumferential wall 15 and the side wall 20 and the angle on the surface side of the chamfered part 22 is set at 90°or less between the tangent b on the internal surface of the outer circumferential wall 15 passing the intersection 23 of the chamfered part 22 with the internal surface of the outer circumferential wall 15 and the chamfered part 22 while the angle on the surface side of the chamfered part 22 is set at 90°or less between the tangent (a) on the internal surface of the side wall 20 passing the intersection 24 of the chamfered part 22 with the internal surface of the side wall 20 and the chamfered part 22. Thus, the pachinko balls rolling along the outer circumferential wall 15 turn the direction of rolling at the angle of 90°or less with the chamfered part 22 to be guided to the ball discharge part 11 thereby causing no jamming with the pachinko balls.
