ABSTRACT:
A drive apparatus for a specimen stage of a microscope suitable for handling specimens of a known shape or internal structural configuration. A coordinate position (Xd, Yd) on a two-dimensional coordinate designating means is made to correspond to coordinate positions (Xs, Ys) of a plurality of specimens of the same configuration on the specimen stage independently and selectively, thereby ensuring that correspondence between each of the plural specimens of the same configuration and a layout drawing of the specimen placed on the two-dimensional coordinates designating means can be set up accurately. A part desired to be observed of a specimen can therefore be moved quickly and easily into a very small field of view of the microscope.
