<P>PROBLEM TO BE SOLVED: To provide a game machine which can improve the retention of a game ball and the attachment of a game board while reducing the number of wasteful part items. <P>SOLUTION: An external wall member 410 of a playfield 30a is formed at a part of an opening in an inner frame, and even if the game board 30 is abolished due to a change of a board type or the like, the external wall member 410 can be used in a new game board, thereby reducing the number of part items which should be abolished. Furthermore, since the external wall member 410 has a protrusion 420 protruding toward the side of the playfield 30a and having a face which is orientated obliquely upward at its prescribed point, the game ball is guided to the playfield 30a by the protrusion 420. Thus even if the displacement of a lateral attachment position between the inner frame and the game board 30 becomes large, the game ball is not retained between the opening of the inner frame and a part on the game board 30, it is not necessary to arrange a nail and a Yakumono (accessory) at the end of the game board, and the nail and the Yakumono are prevented from being hung to a second frame body of the game board at the attachment and are damaged, thereby facilitating installment work. <P>COPYRIGHT: (C)2012,JPO&INPIT |
