摘要： An opaque projector includes a light source, a stage through which the light radiating from the light source passes and on which an object is placed, a projection mirror for reflecting light reflected by the object, and a projector lens for gathering the light reflected by the projection mirror to form an image of the object on an image projecting surface located outside of the projector. A reflection mirror for reflecting the light from the light source to illuminate the object is provided on each of the two sides of the projection mirror. The light source is disposed in front of the projeciton mirror and on the inner sides of the reflection mirrors. The reflection mirrors and light source are disposed at positions relative to each other and to the projection mirror which ensures that the light reflected by the reflection mirrors, and regularly reflected by the object and the stage, is not incident on the projection lens and that the real and virtual images of the light source exist outside of the field angle of the projection lens.
