PROBLEM TO BE SOLVED: To fold a magnifying lens without separating a game unit by forming the magnifying lens member by a base frame, an intermediate frame and a holding frame, displacing the base frame to the intermediate frame at a specific angle, and displacing the holding frame to the intermediate frame at specific angles two times. SOLUTION: A magnifying lens member 10 where an magnifying lens 11 held by a holding frame 1 is mounted in parallel at an upper part of a display face D of a game unit P, comprises an intermediate frame 2 on an upper of which the holding frame 1 is pivotted. A base frame 3 comprising a mounting part 31 of the game unit P is pivotted on a lower part of the intermediate frame 2. On this occasion, the holding frame 1 and the intermediate frame 2 are pivotted by a clutch mechanism which can be changed in three stages at about every 90 degrees through a shaft 12. Further the intermediate frame 2 and the base frame 3 are pivotted by a clutch mechanism which can be changed in two stages at about every 90 degrees through a shaft 33. Whereby the magnifying lens member 10 can be folded without separating the game unit P, and can be stored in a state that both of the magnifying lens member 10 and the game unit P are overlapped. |
