Abstract

PURPOSE: To secure the constant shift direction for the samle image at all times even with variation of the magnification ratio and thus to ensure an easy selection of the viewfield by securing an automatic correction for the shift direction of the sample image caused by the turn of the sample of the electronic microscope.
CONSTITUTION: When the observation magnification ratio of sample 4 is set to standard ratio M0, the signals of the rotary angle corresponding to the zero degree are transmitted to X-direction circuit 14X, 14Y, 15X and 15Y respectively from memory circuit 9. The voltage is increased by X0 via X-direction potentiometer 13X, and thus the variation equivalent of X0 is detected at arithmetic circuit 17X to be led to pulse conversion circuit 12X via gate 18. As a result, pulse motor 11X is driven to shift sample 4 in the X direction by X0. In the same way, sample 4 is shifted in the Y direction with operation of Y-direction potentiometer 13Y. Then the observation magnification ratio is varied from M0 to M1 with operation of lens control circuit 8, and thus sample 4 is shifted in the Y direction by -X0 via potentiometer 13X. In the same way, sample 4 is shifted in the X direction by Y0 via potentiometer 13Y.
