Bar code scanner with scanning beam and/or field of view adjustable about three mutually orthogonal axes

摘要

A scan head is adjustably mounted in a ball-and-socket joint on a scan module or housing of an electro-optical system for reading coded indicia. The scan head is movable about three mutually orthogonal axes intersecting within the scan head, thereby steering a light beam emitted from the head and/or steering a field of view of a sensor.
