摘要：PROBLEM TO BE SOLVED: To form a mechanism to switch positions of movable members compact and thin. SOLUTION: This switching mechanism 1 is provided with a first arm 11 rotatable by a prescribed angle, two shape memory alloy members 31 and 32 installed on one side of a rotation center (a) of the first arm 11 to contract in opposite directions from each other as energization is switched, and a second arm 12 connected on the other side 11b to the rotation center (a) of the first arm 11 to be rotatable in the opposite direction to rotational movement (a) of the first arm 11. As energization is switched to the two shape memory alloy members 31 and 32, the rotational movement position of the first arm 11 is changed, and the rotation move of the second arm 12 is changed by above switching. The electronic device changes the position of the movable member by the switching mechanism 1. COPYRIGHT: (C)2005,JPO&NCIPI
