ABSTRACT:
A bar code symbol reading system for reading bar code symbols disposed on rotating containers, such as cans and bottles, which have various capacities and arbitrary surfaces upon which the bar code symbols are printed. The system includes a laser scanning engine which produces a three-dimensional laser scanning pattern having unique geometrical characteristics over a predefined scanning region, within which each container is rotated. Owing to its unique geometry, the laser scanning pattern facilitates reading of bar code symbols printed on arbitrary container surfaces while rotated within the predefined scanning region. As a result of the present invention, a single bar code symbol reading system can be used to read bar code symbols that are printed on the arbitrary surfaces of cans and bottles.
