Abstract: An improved high resolution scanner for use in a conventional scanner housing. A light receiving guide transversely moves a conventional lens and CCD for scanning portions of an object to be scanned. The resulting scanned portions, when combined, produce a high resolution image of the scanned image.

Abstract: A light diverting channel for use in a scanner. The channel is incorporated into the cover of a flat bed scanner and transmits light from the lamps positioned longitudinally along the scanner, up through the side of the channel, and through a central region or sheet of the channel, and then down through objects to be scanned. The light diverting channel thereby more efficiently uses the light generated by the lamps and more evenly disburses the light over and through the object to be scanned.

Abstract: An optical, multi-resolution scanning apparatus for scanning transparent or opaque objects including a high resolution lens, a low resolution lens, a flip mirror switch which alternates between high resolution mode and low resolution mode of scanning, a flip mirror switch which alternates between transmissive mode and reflective mode of scanning whereby high and low resolution scanning of opaque and/or transparent objects may be accomplished through movement of flip mirror switches, without transverse movement of the lens assembly.

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.
