Title: Game machine
Inventor: OKAMURA GEN
IPC: A63F7/02
Filed: 2019-09-19
Abstract: To provide a game machine capable of uniformly putting out balls in a suitable manner.SOLUTION: When the opening/closing plate 1300 is brought into a second state in which a ball flowing down from the upstream position of a first specific winning port 1000a cannot be guided to the first specific winning port 1000a, a dropping delay plate 3250 is operated to delay the flowing down of the ball. Thereby, it is possible to more easily arrange the ball at the upstream position of the first specific winning port 1000a until the opening/closing plate 1300 is switched to a first state. If the opening/closing plate 1300 becomes the first state while the ball is still at the upstream position of the first specific winning port 1000a, the ball is guided to the first specific winning port 1000a. This makes it possible to reduce the influence of a shooting technique of a player on a volume of substantial putout balls. As the result, it is possible to configure a game machine friendly to beginners.SELECTED DRAWING: Figure 35
