Abstract
An optical scanning apparatus for retrieving digital electronic images representative of opaque and transmissive objects. The apparatus is equipped with a docking port and is operative to scan objects, such as documents and photographs and/or transparencies and slides. A scanning camera equipped with transmissive and reflective light sources for illuminating the corresponding objects may be selected by the operator to retrieve images of either the reflective or transmissive object type.
