11. An automatically-activated laser scanning bar code symbol reading system, comprising:

  • a hand-supportable housing;

    a laser-scanning bar code symbol reading mechanism, disposed in said hand-supportable housing, for repeatedly reading one or more bar code symbols on an object within a predetermined time period, and in response to each new successful reading of one of said bar code symbols within said predetermined time period, producing a new symbol character data string representative of said read bar code symbol;

    a data transmission circuit, disposed in said hand-supportable housing, for transmitting, when activated, a selected one of said produced symbol character data strings to a host system operably connected to said automatically-activated laser scanning bar code symbol reading system;

    a manually-activatable data transmission switch, integrated with said hand-supportable housing, for generating a data transmission control activation signal in response to the actuation of said manually-activatable data transmission switch within said predetermined time period; and

    a system controller for activating said data transmission circuit in response to the generation of said data transmission control activation signal so that a symbol character data string, produced currently with or immediately subsequent to the activation of said manually-activatable data transmission switch, is transmitted to said host system.
