Abstract
Improvements in episcopic projection apparatuses, characterized essentially by the fact of comprising a dark chamber having a transparent upper surface for supporting the image carrier sheet, and a front with a displaceable lens for focusing, and at the same time inside the camera and facing the lens an inclined mirror also displaceable for a second approach, also comprising in both front corners of the camera two luminous spotlights for the illumination of the image carrier sheet, for reflection through the mirror and subsequent projection by the lens.
