Abstract

ABSTRACT OF THE DISCLOSURE

An opaque projector having a stage which transmits illumination light from a light source and on which an object to be projected can be placed. There is a projecting mirror for reflecting light reflected by the object to be projected, and a projecting lens for converging reflected light from the projecting mirror and imaging a projected image of the object on an external projection plane. The opaque projector has a mechanism capable of changing the angle of the stage on which the object to be projected can be placed in such a manner that the object to be projected, the optical axis of the projecting lens and the projection plane meet a Scheimpflug condition.
