ABSTRACT:
An operation microscope apparatus includes: an operation microscope (25) supported to a pillar through an electrically-operated elevating device for rough-motion (first upward-and-downward micro motion device17); a lens support arm (51) supported to a support portion of the operation microscope (25) so as to be movable between a use position at which the lens support arm (51) is extended downward and a storage position at which the lens support arm (51) is stored upward; a front lens (74) held by the lens supported arm (51); a control unit for controlling the electrically-operated elevating device (arithmetic and control circuit27); a switch for upward-and-downward rough-motion (30,31or94,95); and a detection unit for detecting a storage state of the lens support arm (51) to output a detection signal (microswitch91). In the apparatus, only when the detection signal is received, the control unit (arithmetic and control circuit27) controls the electrically-operated elevating device (first electrical upward-and-downward micro motion device17) by operating the switch (30,31or94,95) to allow the operation microscope (25) to roughly move upward and downward.
