ABSTRACT:
An optical scanning apparatus for retrieving digital electronic images representative of opaque and transmissive objects. The apparatus is equipped with a reflective scanning platform for scanning documents and photographs and a docking port for receiving a transmissive scanning platform for scanning transparencies and slides. A scanning camera equipped with light sources for illuminating the respective platforms may be aligned by the operator to retrieve images from either the reflective scanning platform or from the transmissive scanning platform. An optical switch which is included within the optical pathway selectively toggles the view of the scanning camera between the reflective platform and the transparent platform. An operator using a control panel button or software can selectively scan either type of object. The choice of two scanning platforms optimizes the digital image quality for each type of media.
