PURPOSE:To provide an autofocusing mechanism in which a specified moving margin is always secured and focusing function can be sufficiently achieved when the position and angle of a microscope for operation is changed. CONSTITUTION:When an optional origin 16 is set in the moving range E of a driving object part 11, and the microscope for operation is on a free condition at a switch part, a driving means 17 returns the driving object part 11 to the position of the origin 16. Consequently, when the position and the angle of the microscope for operation are changed, the specified moving margin is always secured, so that the focusing function of the autofocusing mechanism 15 can be sufficiently achieved. |
