なる請求項(1)記載の反射型実物投影機。[Claims for Utility Model Registration] (1) A light source, a projection mirror that reflects the light emitted from the light source, and a stage through which the light reflected by the projection mirror can be placed and on which an object to be projected can be placed. , a projection lens for condensing reflected light from the projection object via the projection mirror to form a projected image of the projection object on an external projection surface, the light source being connected to the projection mirror; In the reflection-type physical projectors disposed at opposing positions, the stage includes a light diffusion surface that diffuses the reflected light from the projection mirror, and diffusely reflected light from the projection object via the light diffusion surface. A reflection-type real projector, characterized in that only the reflected light is made incident on the projection lens via the projection mirror. (2) Claim (1) wherein the stage is provided with a light diffusing surface on the side on which the object to be projected is placed, and an anti-reflection film for preventing normal reflection on the surface on the projection mirror side. )Reflection type physical projector described in ).
