PURPOSE:To support movably an objective lens, etc. in both orthogonal directions through simple constitution using no plate spring, by forming a mobile support mechanism with use of a pair of coupling members that connect and support movably a mobile part to a fixed part and a mobile part in two direction orthogonal to each other. CONSTITUTION:For coupling members 3 and 4 for connection of a fixed part 1 and a mobile part 2, two frame-shaped parallel links are hooked at the part 2 and a hook part 6. In such a case, the force that moves the part 2 far away from a post 1' is applied to the part 2 in order to maintain the hook between those hook points. Then both members 3 and 4 can turn in the right and left directions with a straight line parallel to the direction X connecting two hook points 6' defined as a center axis and also can turn in the upper and lower directions centering on the point 6'. Thus the part 2 can turn freely with two parallel straight lines connecting the hook points 6 to the members 3 and 4 defined as the center axes respectively. |
