Abstract: Antique identifying electro-optical marker is associated with a base unit having a receiver. During a set-up mode of operation, an electro-optical reader reads the marker. During subsequent reading of indicia, the reader generates electrical signals which are transmitted to the receiver of the uniquely identified base unit.

Abstract: An optical scanner having an adjustable cradle or stand for allowing the user either to operate the scanner in the hand or while positioned in the cradle. In one embodiment, suitable for use with wireless-based hand-held scanners, a particular scanner may be associated with an individual cradle by scanning a bar code symbol associated with that cradle and storing and/or processing the ID data contained in the symbol. A simple mechanical arrangement is provided for switching the scanner either manually or automatically between one-dimensional and two-dimensional scanning, with corresponding changes in the cross-sectional shape and/or focus of the scanning laser beam.
