Abstract

PURPOSE:To make effective use of rays by using reflecting mirrors without using any condenser lens at all in an irradiation system and a reflection system. CONSTITUTION:An irradiation system 9 is constituted of a light source 10, and a parabola reflection mirror 11 which condenses and reflects light from the light source. A plane reflection mirror 5 inclined 45 deg. with respect to the top surface 1a and bottom surface 1b of the case is disposed in a case 1 in the intermediate position of a stage surface 2 and a Fresnel reflection mirror 4. With the above- mentioned constitution, the rays from the system 9 transmit through the surface 2 and are irradiated onto an object 3 to be projected. The irradiated light is reflected irregularly on the reflection surfaces of the object and is further condensed and reflected by the mirror 4. It is changed of its course by the mirror 5 and is projected onto a screen 8 by a projecting lens 7.
