Abstract
Abstract An exposure medium for producing a reflex exposure of an original image onto a photosensitive surface including a transparent conductive member adapted for positioning proximate to the original image to be reproduced. The exposure medium further includes an opaque conductive member spaced from the transparent conductive member and adapted for positioning proximate to the photosensitive surface. A luminescent member is positioned between the transparent conductive member and the opaque conductive member and is adapted when energized to illuminate the original image through the transparent conductive member. A plurality of light conductive members are disposed throughout the opaque conductive member and the luminescent member for conducting patterns of light reflected from the original image through the opaque conductive member and thus exposing the photosensitive surface according to the reflected light patterns. The light conductive members include light insulating means associated therewith and with the luminescent member for preventing the direct illumination of the luminescent member from reaching the photosensitive surface.
