Abstract
A system for reading bar code symbols or the like, having a scanner for generating a laser beam directed toward a target and producing a first narrowly spaced apart dual line scanning pattern that enables the user to manually aim and direct the beam to the location desired by the user and a relatively wider spaced apart dual line second scanning pattern that 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.
