Abstract
A system for reading bar code symbols or the like, including one- or two-dimensional bar code symbols having a scanner for generating a laser beam directed toward a target and producing a narrow first raster scanning pattern that enables the user to manually aim and direct the beam to the location desired by the user and a second raster scanning pattern that increases in height which sweeps an entire symbol to be read, and a detector for receiving reflected light from such symbol to produce electrical signals corresponding to data represented by such symbol.
