<P>PROBLEM TO BE SOLVED: To provide a game machine for easily maintaining each game nail on the left top corner of a game board when the game board is opened by a middle door while securing appropriately the facing gap between the middle door and the board when the board is closed by adopting various measures to the open/close structure of the middle door mounted between a front door and an inside frame. <P>SOLUTION: The left end of a front door is turnably supported in the front and back direction on the left end of an outside frame F. A middle door Qa is mounted between the front door and the inside frame W of a game machine body B. By the displacement turning mechanism Qb, while the middle door Qa displaces the left end of a frame 10 to the right side along a guide bar 30 on both top end bottom sides, it turns/moves the right end of the frame 10 to the left front side with the left end of the frame 10 as an axis and opens the board face of a game board P to its right side. Moreover, while it displaces the left end of the frame 10 to the left side along the bar 30, it turns/moves the right end of the frame 10 to the right back side with the left end of the frame 10 as an axis and closes the board face of the board P from its right side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
