Abstract

An operation microscope apparatus includes: an operation microscope () supported to a pillar through an electrically-operated elevating device for rough-motion (first upward-and-downward micro motion device); a lens support arm () supported to a support portion of the operation microscope () so as to be movable between a use position at which the lens support arm () is extended downward and a storage position at which the lens support arm () is stored upward; a front lens () held by the lens supported arm (); a control unit for controlling the electrically-operated elevating device (arithmetic and control circuit); a switch for upward-and-downward rough-motion (or); and a detection unit for detecting a storage state of the lens support arm () to output a detection signal (microswitch). In the apparatus, only when the detection signal is received, the control unit (arithmetic and control circuit) controls the electrically-operated elevating device (first electrical upward-and-downward micro motion device) by operating the switch (or) to allow the operation microscope () to roughly move upward and downward.
