Abstract

PURPOSE:To form the image of the reflected light from an object in the outside part of a lens barrel and facilitate the position detection of the working point of the object by providing a transmitted light reflection plate on the light source side of the objective lens of the lens barrel. CONSTITUTION:A transmitted light reflecting mirror 13 is interposed between the condenser lens 11 of an objective lens barrel 17 and an objective lens 12 at its bottom end. Then, part of the light reflects on the surface, is cast to a detecting reflection plate 20, is conducted to the outer side of the lens barrel 17 and is imaged on a screen 16 via the lens 14 in a detecting barrel 15. Hence, the operator can see the formed image without daring the danger incentive to his eyes.
