ABSTRACT:
A surgical microscope unit which is compact and operated lightly at high stability has first and second parallelogrammic linkages, interlocking mechanisms for interlocking the first and second parallelogrammic linkages, a counterweight connected to an arm of the second parallelogrammic linkage, flexible movement transmitting members for transmitting tilting movements of the microscope body around pivot axes directly to a tilting rod as tilting movements around pivot axes at the same ratio, and a movement controlling mechanism for limiting a moving locus of the tilting rod to a corresponding location at which the microscope unit is set. The pivot axes are arranged so that a triangle formed by connecting the pivot axes is similar to a triangle formed by connecting the pivot axes in a plane parallel with a plane including a vertical axis. Auxiliary counterweights are provided on members interlocking with either the first interlocking mechanism or the second interlocking mechanism. When the microscope body is moved, the balancing weight does not project from the microscope body.
