Abstract:
An apparatus for scanning a media, comprising;a sensor for receiving an exposure of an image;a low light illumination system for providing an exposure light comprising a low light source and an integration chamber for receiving light from said light source, said integration chamber having an exit opening for allowing said exposure light to exit said integration chamber; anda gate assembly slidably mounted to said apparatus, said gate assembly having a frame member having an exposure aperture which is in optical alignment with said sensor and said exit opening such that said exposure light will pass through a media positioned at said exposure aperture onto said sensor, a clamp member moveably mounted to said frame member between an exposure position and non-exposure position, and a light conduit mounted to said clamp member, said light conduit having a first opening at one end adjacent said exposure aperture and a second opening at the other end disposed adjacent said exit opening, said first opening having a configuration equal to or greater than said exposure aperture, said second end having an outwardly extending lip which extends around at least a portion of said second opening and having a configuration such it mates within said exit opening, said lip having a reflective surface for reflecting a portion of light back into said integration chamber for increasing of the brightness for exposure onto the media.
