Abstract:
An apparatus for viewing originals in a flatbed scanner includes a fixed copy holder and a movable scanning unit with a light source for illuminating the original to be scanned, an optoelectronic transducer, and a scanning lens for projecting a scanned line of the original onto the optoelectronic transducer. Fitted below the copy holder is a light source, and fastened on the scanning unit is a dispersion foil drawn under the copy holder by the scanning unit when the scanning unit is brought into a parking position and drawn away by the scanning unit when the scanning unit is moved over the copy holder during scanning. The dispersion foil is stretched tight by a suitable stretching apparatus when the scanning unit is in the parking position.
