Abstract

Image viewing apparatus comprises a transparent platen on which an image to be scanned can be positioned. A scanning system support is movable alongside the platen. A light source illuminates the platen from the same side as the scanning system support. A light diffuser can be moved between a first position in which it is located between the light source and the platen whereby light from the light source is diffused across the platen, and a second position in which the light diffuser is positioned so as not to impede a scanning system on the support from viewing an image on the platen.
