What is claimed is: 1. An automatically-activated bar code symbol reading system for carrying out bar code symbol reading operations, comprising: a hand-supportable housing; a manually-actuatable data transmission activation switch integrated with said hand-supportable housing; an automatically-activated laser scanning bar code symbol reading subsystem, disposed within said hand-supportable housing, for automatically producing a visible laser scanning pattern and repeatedly reading a bar code symbol on an object within a predetermined time period using said visible laser scanning pattern, and each instant said bar code symbol is read within said predetermined time period, automatically producing a 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 by the manual actuation of said manually-actuatable data transmission activation switch, a selected one of said produced symbol character data strings to a host system or data storage device; and a system controller for controlling said data transmission circuit so that the symbol character data string, produced at substantially the same time when said symbol character data transmission activation switch is manually actuated, is transmitted to said host system or data storage device; and wherein said automatically-activated bar code symbol reading system further includes (i) a preprogrammed set of operational states wherethrough said automatically-activated bar code symbol reading system automatically passes during each bar code symbol reading operation, and (ii) a preprogrammed symbol character data transmission state of operation into which said automatically-activated bar code symbol reading system is automatically induced in response to the manual-actuation of said manually-actuatable data transmission activation switch. 2. The automatically-activated bar codc symbol reading system of claim 1, wherein said preprogrammed set of operational states include a bar code presence detection state of operation and a bar code symbol reading state of operation. 3. The automatically-activated bar code symbol reading system of claim 2, wherein said preprogrammed set of operational states further include an object detection state of operation. 4. The automatically-activated bar code symbol reading system of claim 3, which further comprises an objection detection subsystem realized using either infrared (IR) signal transmission/receiving technology, or low-power non-visible laser beam signaling technology, for automatically detecting an object within an object detection field defined relative to said hand-supportable housing. 5. The automatically-activated bar code symbol reading system of claim 2, wherein a set of color-encoded state indicating light sources on an exterior of said hand-supportable housing sequentially generate a visually-perceptible object detection indication signal when the system is automatically induced into its object detection state of operation, a visually-perceptible bar code symbol presence detection indication signal when the system is automatically induced into its bar code symbol presence detection state of operation, and a visually-perceptible bar code symbol reading indication signal when the system is automatically induced into its bar code symbol reading state of operation, during each automatic bar code symbol reading cycle carried out by said automatically-activated bar code symbol reading system. 6. The automatically-activated laser scanning bar code symbol reading system of claim 2, which further comprises an object detection subsystem disposed within said hand-supportable housing and including infrared (IR) signal transmission/receiving circuitry for automatically detecting said object within an object detection field definable relative to said hand-supportable housing. 7. The automatically-activated laser scanning bar code symbol reading system of claim 2, which further comprises an objection detection subsystem disposed within said hand-supportable housing, and including a low-power non-visible laser beam signaling mechanism for automatically detecting said object within an object detection field definable relative to said hand-supportable housing. 8. The automatically-activated bar code symbol reading system of claim 1, which further comprises a set of color-encoded light sources provided on an exterior of said hand-supportable housing for sequentially generating a set of visually-perceptible state indication signals that visually indicate, to a user of said system, the various states of operation, wherethrough said system automatically passes during each instance or automatic bar code symbol reading. 9. The automatically-activated laser scanning bar code symbol reading system of claim 1, which further comprises an indicator, integrated with said hand-supportable housing, for indicating each instance of when a bar code symbol is read by said automatically-activated laser-scanning bar code symbol reading mechanism and a symbol character data string representative thereof is produced and transmitted to said host system or said data storage device. 10. The automatically-activated laser scanning bar code symbol reading system of claim 1, which further comprises: a hand-held mode of automatic operation and a countertop-supported mode of automatic operation; and a mode selection mechanism integrated with said hand-supportable housing, for generating said data transmission control activation signal when said hand-supportable housing is placed in a stand for supporting said hand-supportable housing during said countertop-supported mode of automatic operation. 11. The portable hand-supportable data terminal of claim 1, wherein said automatically-activated laser scanning bar code symbol reading subsystem comprises a laser diode for producing a visible laser beam.
