ABSTRACT:
In order to make the visibility of a right optical system to be the same as that of a left optical system even when there is a vibration and to simplify a drive mechanism, a pair of right and left correction lenses are respectively disposed between a pair of right and left objective lenses and a pair of right and left eye pieces. The pair of right and left objective lenses are integrally supported by a correction lens support frame. When there is a vibration, the correction lens support frame is moved, together with the pair of right and left correction lenses, by a correction lens moving mechanism in X and/or Y directions which cross each other at right angles in a plane perpendicular to the optical axis of each of the optical systems.
