Imaging system for producing reduced or enlarged images of an original document

An illumination and imaging housing for uniformly illuminating a document placed on a transparent surface thereof and for projecting an image of said document onto a photosensitive image plane, said housing comprising:

• a frame member having a diffusely reflecting interior side surface,
• a roof assembly having a diffusely reflective interior surface and having a transparent document platen in a central aperture thereof, said roof assembly adapted to be vertically movable in light-tight sliding contact along the surface of one end of said frame member,
• a floor assembly having a projection lens mounted therein, and having a diffusely reflective interior surface, said floor assembly adapted to be vertically movable in light-tight sliding contact along the surface of the other end of said frame member, and
• a flash illumination source mounted on the interior surface of said frame member,
• whereby when said illumination source is activated, light is diffusely reflected from the interior surfaces to the surface of said platen, the efficiency of said light reflection dependent on the relative position of the movable floor and roof assemblies.
