<P>PROBLEM TO BE SOLVED: To provide a game machine capable of positioning a movable member into a fixed position with a simple configuration. <P>SOLUTION: A first movable member 34 is disposed at a pair of racks 42, 42 disposed at a device body and movable in a vertical direction. An operating gear 45 meshed with each rack 42 is formed with a deformed part 49 that cannot be meshed with a rack tooth part 46a of the rack 42. In the original position of the first movable member 34, operating tooth parts 47b of the operating gears 45 are meshed with the rack tooth parts 46a of the racks 42, and the operating gears 45 are rotated in a normal rotating direction by a motor 40 to move the first movable member 34 upward integrally with the racks 42, 42 by the mesh action of both gear parts 46a, 47b. When the first movable member 34 reaches an operating position, the deformed parts 49 of the operating gears 45 abut on the rack tooth parts 46a of the racks 42 to regulate the rotation of the operating gears 45 and the movement of the racks 42 to thereby position the first movable member 34 into the operating position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
