<P>PROBLEM TO BE SOLVED: To prevent fraud due to a game ball with a thread. <P>SOLUTION: If a thread is attached to a game ball 15, the thread is wound around a thread tangling passage member 45 along a game ball passage 42 of the thread tangling passage member 45. The thread prevents the game ball 15 from entering a ball-feeding lever. Even if the game ball 15 enters the ball-feeding lever by some accident, the thread prevents the game ball 15 with the tread from being discharged onto a shooting platform of a shooting device. As a result, the game ball with the thread is not shot, and therefore, fraud due to the game ball with the thread can be prevented. The thread tangling passage member 45 is configured to be detachable from an upper tray 55. In detaching the thread tangling passage member 45 from the upper tray 55, the tangled thread can be easily removed and the game can be quickly restarted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
