<P>PROBLEM TO BE SOLVED: To prevent fraud using a stringed game ball. <P>SOLUTION: If a rotation portion rotates by 90° from a state shown in Figs. 9 (a) and 9(b), a game ball 15 enters a game ball holding portion 77a (Figs. 9(c) and 9(d)). The game ball 15 is rotated together with the rotation portion 43. If the rotation portion 43 rotates by 180° from this state, the game ball 15 enters a launching unit 94 from a ball discharge port 49 and is placed on a launching pad 47. If the game ball 15 is stringed, the string is taken up to the rotation portion 43, and the string prevents the game ball 15 from being placed on the launching pad 47. Even if the game ball 15 is placed on the launching pad 47, the string continues to be taken up to the rotation portion 43. Therefore, even if a hammer (not shown) hits the game ball 15 on the launching pad 47, it is extremely difficult for the game ball 15 to reach the game region 3, thereby preventing fraud using a stringed ball. <P>COPYRIGHT: (C)2013,JPO&INPIT |
