Abstract
An automatically-activated code symbol reading system includes a hand-supportable housing having a light transmission aperture through which a field of view (FOV) passes; and an automatically-activated bar code symbol reading mechanism for repeatedly reading code symbols on an object in the FOV, within a predetermined time period, and in response to each new successful reading of the code symbols, producing a new symbol character data string representative of the read code symbol. A system control subsystem (i) automatically activates the automatically-activated bar code symbol reading mechanism in response to the detection of the object in at least a portion of the FOV, and (ii) automatically activates the data transmission circuit in response to the generation of the data transmission control activation signal so that a symbol character data string, produced currently with or immediately subsequent to the activation of the manually-activatable data transmission switch, is transmitted to a host system.
