ABSTRACT:
A rigid cylindrical roller for use in portable optical scanners. The roller includes a thinned midsection and a plurality of grooves. A plurality of compressible, surface gripping rings are fitted onto the plurality of grooves. Each surface gripping ring is held relatively immobile with respect to one another as well as to the roller. In one embodiment, the roller, the grooves, and the compressible rings are dimensioned such that in use, the surface-gripping rings are compressed inside the grooves at the points of rolling contact, permitting both the roller and the rings to come into contact with the scanned surface.
