Abstract
A display unit equipped with a copying device. The display unit has a double-sided display panel secured at the front of unit housing, a light shield film movably provided behind the display panel in parallel and spaced relation to the latter, a guide plate for a photosensitive copy paper sheet fixedly provided behind the shield film, and associated devices for developing the copy paper sheet. The shield film has a compact exposure member of image transmitters formed of a plurality of graded index fibers in bundled configuration which can advantageously direct, when desired, the image rays at the back surface of the display panel onto the copy paper sheet while the same images are being observed with the naked eye at the front of the panel.
Claims7
A display unit equipped with a copying device comprising:
- a double-sided display panel fixedly mounted at the front of the display unit;
- a light shield film movably supported behind said display panel in a position parallel with and at a fixed distance from said panel;
- winding members at the opposite ends of said display panel between which said light shield film extends and around which the ends of said light shield film are wound for selectively winding said light shield film along said display panel;
- a corona charger, an exposure member including a plurality of image transmitters constituted by a bundle of optical fiber lenses of graded refractive index, and a stop releasing member connected to each other for movement together and integrally connected in said light shield film for simultaneous movement with said light shield film with said corona charger being positioned ahead of said exposure member relative to the direction of movement thereof during the exposure of the copy paper to the image and said stop releasing member being located in a position for actuating the stop member at the termination of said exposure of the copy paper to said image;
- means for selectively driving said winding members;
- a guide member fixedly mounted on said unit at a position behind said light shield film in spaced and parallel relationship to said light shield film for guiding a photosensitive copy paper into said unit and supporting it therein;
- a stop member along said guide member for holding the copy paper in exposure position along said guide member, said stop member being movable for releasing said copy paper, and associated developing means for said copy paper adjacent said guide member for receiving the copy paper from said guide member after it has been released, whereby when a copy is to be made, copy paper is positioned on said guide member and said winding members are driven to move said corona charger, exposure member and stop releasing member parallel to said guide member between the guide member and the display panel for charging the copy paper, exposing it to the image from the rear of the display panel, and engaging the stop member for releasing the copy paper when it has been completely exposed.
