    摘要: A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The resolution of the digitized representation of the scanned original document can be determined independently of the selection of object focal plane.

    摘要: A scanning apparatus providing separate fixed object focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The illumination source comprises a removable lamp cartridge with one or more lamps disposed for correct illumination of the selected object focal plane.

    摘要: A scanning apparatus providing separate fixed focal planes for transmissive and reflective original documents to be scanned, wherein a scan carriage containing illumination, sensor, and optical elements is moved together to scan an original document and to obtain a digitized representation thereof. The movable scan carriage has an illumination source disposed between the reflective and transmissive object focal planes, with the object focal plane to be used selected by changing the position of one or more optical elements within the scan carriage. The resolution of the digitized representation of the scanned original document can be determined by rotation of at least one lens about an axis substantially perpendicular to its optic axis.

    摘要: A flat-bed scanner for scanning an original document, comprising a scanner housing and a scan carriage movably disposed for motion relative to the scanner housing. A sensing system is mounted to the scan carriage for scanning the original document. A media holder supports the original document for scanning along a scan line such that the original document is positioned at an object focal plane of the sensing system. The media holder support system dynamically maintains a portion of the original document proximate to the scan line coincident with the object focal plane during scanning. The support system includes a first mounting device pivotally attaching a first end of the media holder to the housing for allowing a pivot motion of the media holder with respect to the scanner housing and a second and a third mounting device are affixed and movable with the scan carriage for movably supporting the media holder during the motion of the carriage. The second and third mounting device support the media holder substantially below the scan line and proximate to marginal edges of the media holder outside the field of view of the scan line.
