Abstract

PURPOSE: To aim at multifunctioning, by providing movable cross head and stage and illumination lamp, in the upper part of casing containing the optical system.
CONSTITUTION: On a casing 1 of which upper end alone is opened and the lower end is closed with light transmitting and diffusion plate 2 of opaque white semitransparent plastic material, housing an optical system 3 containing condenser lens 3e therein are provided a cross head 5 by means of fixed rail 4, a stage 7 through movable rail 6 on the cross head, and a projecting lens 11, an illumination lamp 12, and a reflecting mirror 14 in the upper part thereof. When a slide file sheet 8 having slide film and other transparent object or postage stamp or other non-transparent object arrayed in grid form in lateral and longitudinal directions is mounted on the stage 7, the objects, whether transparent or non-transparent, can be projected independently or continuously. In addition, semitransparent substance, such as body tissues sampled on a slide glass, may be projected clearly, even the changes in the thicknesswise direction, by using light source lamp 3a and illumination lamp 12 simultaneously.
