ABSTRACT:
A portable bar code scanner comprises a housing member having a pair of sloping supporting surfaces oriented at an angle to each other and a floor portion on which is mounted a reflecting mirror. One of the sloping supporting surfaces includes a transparent substrate. A portable hand-held optical scanner is positioned adjacent the other sloping supporting surface for projecting a plurality of scanning light beams in the form of a scan pattern at the reflecting mirror which reflects the scan pattern onto the transparent substrate over which a bar code label is passed enabling the scanning light beams to scan the bar code label. A magnet mounted adjacent the other sloping supporting surface is sensed by a sensor mounted in the hand-held scanner for generating control signals which are used in operating the scanner in different modes of operation depending on whether the scanner is mounted on the housing or when the scanner is used to freely scan a bar code label.
