Abstract: A precision holder for hand-held optical scanning digitization devices is provided in which varying thicknesses of source documents may be securely held to a flat table by a support which also functions as a guide along which the scanning device may be accurately and repeatedly moved. In one embodiment, the original document is held by a guide held by a double hinge arrangement and secured by springs pulling toward the table. In another embodiment, the guide is held to the table by springs in a frame and track assembly much like a guillotine. For more accurate use of the scanning device a scanner alignment tray is provided for attachment to allow precise use of scanning devices which do not have a suitable square side to fit against the guide of the described scanning table.
