ABSTRACT:
In an image projecting device for optically projecting the image of a document onto a screen, a film responsive to light is capable of changing, when illuminated, its state for selectively transmitting or diffusing incident light. More than one mirrors are provided for reflecting a reflection from a document image. A focusing lens focuses light reflected from the more than one mirrors onto the film to thereby transfer the document image to the film. A light source illuminates the film in which he document image is formed. A projecting unit projects, in an enlarged scale, light issuing from the light source and being transmitted through the film.
