PROBLEM TO BE SOLVED: To provide a game ball conveying gutter, etc. which can efficiently accumulate game balls with a simple structure, and can be caused to function as a buffer for a difference between processing capacity of a counting machine and processing capacity of a pumping device.SOLUTION: A recovery gutter 13 is composed of an upper gutter 17, a lower gutter 19, etc. The upper gutter 17 is connected to a counting machine 11 through an acceleration gutter 23. The upper gutter 17 is provided above the lower gutter 19, and is shorter than the lower gutter 19. The upper gutter 17 has a plurality of holes 21. The holes 21 may be of the width for allowing game balls to pass through them, which is approximately 15 mm, for example. The holes 21 are formed in the vicinity of both sides in the width direction of the upper gutter 17. The respective holes 21 formed on both sides are formed at positions deviated from each other in the longitudinal direction. Namely, the holes 21 are arranged in a zigzag manner in the longitudinal direction of the upper gutter 17. |
