ABSTRACT:
The invention relates to an automatic focusing mechanism for an operation microscope. In the apparatus in accordance with the invention, when the position and angle of the operation microscope is altered by the operator, a constant moving margin is always secured so that the automatic focusing mechanism has sufficient room to perform the focusing function. This is accomplished by setting an optional origin position within the moving range of the drive objective section of the operation microscope. When the operation microscope is brought to a free condition by a switch section, a driver mechanism operates so as to return the drive objective section to the location of the origin position. Thus, when the position and angle of the microscope is altered, a constant moving margin of the drive objective section is always maintained. Thus, the location of the drive objective section always has sufficient room to perform the automatic focusing function.
