Abstract

PURPOSE: To achieve automatic measurement of a position easily by gathering images of surrounding areas alone of an object being measured using a prism or a flat mirror.
CONSTITUTION: An image of an object 21 being observed for measurement is gathered onto an image gathering surface 23 by an object lens 22. This image- gathering surface 23 is provided with an image-catching element 24, such as ITV, face sensor, etc., so that the image is measured. Further, by arranging parallelogram prisms 25 and 26 on the front side of the image-gathering surface 23 symmetrically to light axis, of the image of the object 21 being observed, that of senter section is eliminated and only that of the surrounding area is gathered onto the image- cating elements 25 and 26 through the prisms 25 and 26.
