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.

Scanning system for scanning reflective and transmissive images

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. A dark slide provides protection against flare during scanning, and can be closed to provide for dark current calibration as well as to seal the system from dust when not in use.

Combined dust protection and dark calibration slide for a flat-bed

A scanning apparatus providing an object focal plane for 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 carnage further includes an automatically-positioned alignment grid for aligning original documents, such that the grid is visible at the surface and moves with the scan carriage.

Apparatus for alignment of material to be scanned in a flat-bed scanner

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 scan carriage is suspended along an axis substantially parallel to a scan line of a scanned original document and passing through a point substantially coincident with the scan line, thereby minimizing variations in lighting conditions due to vibration of the scan carriage.

Scanner drive system having minimum rotational error carriage suspension

An athermalized optical system and method are disclosed. A thermally compensating portion of the optical system is employed to compensate for mechanical and optical thermal effects in the entire optical system. In the preferred embodiment, the optical system comprises an imaging system having a laser diode light source, a collimating lens, a rotating mirror, a scan lens and a media transport. Temperature compensation of the imaging system is obtained by varying the spacing between the laser diode and the collimating lens to decollimate the laser light beam as a function of the system wide temperature effects.
