Title: game machine
Inventor: KASAHARA YUTAKA
IPC: A63F7/02
Filed: 2021-06-24
Abstract: To prevent clogging of a game ball, while effectively decelerating the game ball and promoting inflow to a winning area.SOLUTION: A projection amount of second deceleration piece 21b is formed smaller than that of a first deceleration piece 21a, and a lower end of the second deceleration piece 21b is formed into such a shape that a game ball can come into contact therewith at one point. Thereby, when an opening/closing member 16a is closed, a game ball is clamped between a cover 13b of a ball passage unit 13 and the opening/closing member 16a, so that when the game ball tries to escape upward, this configuration can smoothly release the game ball upward. Accordingly, when the opening/closing member 16a is closed, this configuration can prevent the game ball from being clamped and clogged therein. Since an uppermost-stream second deceleration piece 21b has a larger projection amount than those of three downstream-side second deceleration pieces 21b, the game ball reliably comes into contact with the second deceleration piece 21b and the flow-down speed of the game ball can be reliably decelerated.SELECTED DRAWING: Figure 4
