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.
Claims6
A portable scanning table, for use with a hand-held optical scanner for scanning material to be scanned, said scanning table comprising a table having a length a flat top for receiving the material to be scanned, a guide carried by said table, said guide defining a continuous, linear, surface extending the length of the table for guiding movement of said scanner along said flat top of said table, means for confining motion of said guide to a linear path extending perpendicular to said flat top of said table, and means for resiliently urging said guide against said flat top, so that said material to be scanned can be held between said guide and said flat top, and said optical scanner can be slid along said linear surface of said guide for scanning said material to be scanned.
A portable scanning table, for use with a hand-held optical sensor for scanning material to be scanned, said scanning table comprising a table having a flat top for receiving the material to be scanned, a guide carried by said table, means for preventing motion of said guide along said flat top of said table, and means for resiliently urging said guide against said flat top, so that said material to be scanned can be held between said guide and said flat top, and said optical scanner can be slid along said guide for scanning said material to be scanned, a compressible gasket fixed to said guide between said guide and said flat top of said table, wherein said means for resiliently urging said guide against said flat top comprises at least one spring extending between said table and said guide, and further including hinge means for movably attaching said guide to said table, said hinge means comprising a double hinge fixed to said guide and said table for allowing motion of said guide relative to said table.
