Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 204 words
A specimen stage drive apparatus for a microscope comprising: a specimen stage carrying a plurality of specimens of the same structural configuration and movable in two-dimensional directions; a moving means connected to said specimen stage to move it in the two-dimensional directions; two-dimensional coordinates designating means on which a drawing illustrative of an internal structural configuration of said specimens is placed; designating means for designating a desired position on said two-dimensional coordinates designating means; a controller, connected between each moving means and said two-dimensional coordinates designating means, for correctively setting up correspondence between a coordinate system (Xd, Yd) on said two-dimensional coordinates designating means and a coordinate system (Xs, Ys) for said specimen stage and for controlling said specimen stage such that it is moved to a position of said coordinate system (Xs, Ys) which corresponds to a designated coordinate position on said two-dimensional coordinates designating means; a manual driving means connected to said controller to drive said moving means; and a function selecting means connected to said controller to perform selection of said specimens and coordinate correction, whereby a coordinate position on said two-dimensional coordinates designating means is made to correctively correspond to a plurality of coordinate positions on said specimen stage independently.
Claim 2
Dependent Claim 204 words
A specimen stage drive apparatus for a microscope comprising: a specimen stage carrying a plurality of specimens of the same structural configuration and movable in two-dimensional directions; a moving means connected to said specimen stage to move it in the two-dimensional directions; two-dimensional coordinates designating means on which a drawing illustrative of an internal structural configuration of said specimens is placed; designating means for designating a desired position on said two-dimensional coordinates designating means; a controller, connected between each moving means and said two-dimensional coordinates designating means, for correctively setting up correspondence between a coordinate system (Xd, Yd) on said two-dimensional coordinates designating means and a coordinate system (Xs, Ys) for said specimen stage and for controlling said specimen stage such that it is moved to a position of said coordinate system (Xs, Ys) which corresponds to a designated coordinate position on said two-dimensional coordinates designating means; a manual driving means connected to said controller to drive said moving means; and a function selecting means connected to said controller to perform selection of said specimens and coordinate correction, whereby a coordinate position on said two-dimensional coordinates designating means is made to correctively correspond to a plurality of coordinate positions on said specimen stage independently.
Claim 3
Dependent Claim 48 words
A specimen stage drive apparatus for a microscope according to claim 1 wherein coordinate values indicative of two points of a specimen are inputted to said apparatus to set up the correspondence between coordinate system on said two-dimensional coordinates designating means and coordinate system for said specimen stage.
Claim 4
Dependent Claim 153 words
A specimen stage drive apparatus for a microscope according to claim 1 wherein said controller has (1) a function of calculating a plurality of parameter sets each corresponding to each of plural specimens and storing calculated parameter sets separately, ##EQU3## where θn: relative angle between an n-th specimen (n:integer n>1) and a layout drawing illustrative of an internal structural configuration of specimens, Xs 1 , Ys 1 , Xs 2 , Ys 2 : coordinate values on said specimen stage, Xd 1 , Yd 1 , Xd 2 , Yd 2 : coordinate values on said two-dimensional coordinates designating means, and (2) a function of selecting said parameters Kn, θn, Xon and Yon, and calculating a coordinate position (Xsn, Ysn) on said n-th specimen stage in accordance with Xsn=Kn(Xd cosθn-Yd cosθn)+Xson Ysn=Kn(Yd cosθn+Xd cosθn)+Yson, where Xso and Yso represent reference coordinate values, to thereby move said n-th specimen stage to a desired position.
