Abstract
A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read. A trigger manually displaceable from a first position to a second position produces a first light beam for aiming or positioning the reader. The trigger is automatically returnable, or held in the second position, or manually displaceable from the second position to the first position for initiating a scanning beam pattern for reading the symbol. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol.
