ABSTRACT:
A scanner using a small, inexpensive CCD array for accurately and easily re-creating an error free reproduction of any scanned image wherein a plurality of laser alignment marks are temporarily projected, from an inexpensive solid state laser via a low cost plastic fiber optic cable, onto the surface of the document, and capturing the image as a number of small segments, along both the horizontal and vertical dimensions of the document onto the surface of the image being scanned. These temporary, projected, alignment marks permit the accurate positioning of adjacent, scanned segments during reconstruction of the scanned document. This scanner can scan documents of any width with an accuracy such that the scanned document can be readily, easily and accurately reassembled regardless of the insensitivity of, or misalignment of the scanning array in the apparatus or the skew of the document relative to the camera doing the scanning.
