Abstract
An optical scanning device, which includes a transparent support plate having a supporting surface on which an original is positioned, a scanner carriage being mounted for transverse movement below the support plate on two guide elements extending parallel to each other characterized by the guide elements being frame parts having surfaces forming the guide tracks for the carriage and also having surfaces facing the guide tracks for engaging the supporting surface of the support plate so that the distance between the supporting surface and the scanner is determined by the position of the seating surface relative to the guide track.
