Abstract:
A system for electro-optically reading bar code symbols, comprising:a) a housing movable relative to a symbol to be read during an aiming mode of operation;b) a reader in the housing, including a light source for directing a light beam toward the symbol for reflection therefrom, a light sensor having a field of view and operative for detecting light reflected from the symbol and for generating an electrical signal indicative of the detected light, and a scanner for scanning at least one of the light beam and the field of view during a scanning mode of operation; andc) a trigger switch on the housing, said trigger switch being manually displaceable by a user from a first position to a second position for activating the reader during the aiming mode to direct the light beam out of the housing onto the symbol to enable the user to move the housing and position the light beam on the symbol, said trigger switch being releasable from the second position and automatically returnable to the first position for activating the reader to initiate the scanning mode.
