Abstract

PURPOSE:To make effective use of irradiated light by condensing the light irregularly reflected on the reflection surface of an object to be projected with a condensing reflection mirror, and feeding the same to a projection lens. CONSTITUTION:The rays from a light source 3 and the rays reflected by a parabola reflection mirror 4 are cast onto the reflection surface of an object 11 to be reflected by a plane reflection mirror 6 through the small hole 9 of a plane reflection mirror 8 disposed obliquely above an irradiation system 2. Then, they reflect irregularly on the reflection surface thereof, and the reflected light thereof is bent of its course by the mirror 8 and falls onto a Fresnel reflection mirror 12 mounted to a case side wall 1b. This reflected light is reflected by the mirror 12, is condensed and passes through the small hole 9, enters a projecting lens 13, and is projected to a screen 14 by the lens 13.
