PURPOSE:To realize high rigidity by simple structure and to perform focusing with higher accuracy. CONSTITUTION:This mechanism is equipped with a coarse adjustment board 6 which is supported so as to freely move in an optical axis direction in a microscope main body 4, a coarse adjustment mechanism 8 for coarsely adjusting the board 6, a fine adjustment board 13 which is supported so as to freely move in the optical axis direction on the board 6 and to which a sample plate, or an objective lens 1 is attached, and a fine adjustment mechanism 18 for finely adjusting the board 13 by a displacement causing element 15 fixed on the board 6. |
