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.
