In a stand apparatus for a medical optical instrument, a first link mechanism (4) including a first pantograph arrangement (7) has a proximal end (8) which is mounted on a body (1) having a horizontal groove (14). The body (1) is rotatable about a vertical axis. The first pantograph arrangement (7) has an intermediate section (15) which is slidably engaged within the horizontal groove (14). The first pantograph arrangement (7) reciprocating linearly along a horizontal direction has a forward end (10) on which a horizontal moving element (2) having a vertical groove (30) is mounted. A second link mechanism (5) including a second pantograph arrangement (29) has a proximal end (36) which is mounted on the horizontal moving element (2). The second pantograph arrangement (29) has an intermediate section (3) which is slidably engaged within the vertical groove (30) in the horizontal moving element (2). The medical optical instrument (3) is supported at a forward end (32) of the second pantograph arrangement (29) which reciprocates linearly along a vertical direction. A counter weight for canceling a weight of the medical optical instrument is provided within the first link mechanism. <IMAGE> |
