摘要：The coarse/fine adjustment coaxial handle for feeding microscope stage comprises a feed screw shaft (2), a tubular member (7) rotatably fitted over the feed screw shaft and equipped with a disc plate (8) fixed thereto, a fine adjustment handle (10) rotatably fitted over the tubular member and surrounding the (7) disc plate (8), a reduction gear mechanism (11,12,13) interposed between the feed screw shaft and the fine adjustment handle, a first frictional resistance imparting mechanism (A) for imparting frictional resistance to the tubular member, second frictional resistance imparting mechanism (B) for imparting frictional resistance to the disc plate, and a coarse adjustment handle (23) pivoted to an eccentric position on another disc plate (22) connected to the disc plate (8). The coarse/fine adjustment coaxial handle permits very fine stage feeding without fail and coarse adjustment smoothly with simple operations.
