Disclosed is an automatically-activated wireless code symbol reading system
comprising a bar code symbol reading mechanism contained within a hand-supportable
housing having a manually-activatable data transmission switch. During symbol reading
operations, the bar code symbol reading mechanism automatically generates a visible
laser scanning pattern for repeatedly reading one or more bar code symbols on an
object during a bar code symbol reading cycle, and automatically generating a new
symbol character data string in response to each bar code symbol read thereby.
During system operation, the user visually aligns the visible laser scanning pattern
with a particular bar code symbol on an object (e.g. product, bar code menu, etc.)
so that the bar code symbol is scanned, detected and decoded in a cyclical manner.
Each time the scanned bar code symbol is successfully read during a bar code symbol
reading cycle, a new bar code symbol character string is produced, while an indicator
light on the hand-supportable housing is actively driven. During the bar code symbol
reading cycle, the user actuates the data transmission switch producing a data
transmission control activation signal and enabling a currently or subsequently
produced symbol character data string to be automatically selected and transmitted
to the host system. By virtue of the present invention, automatically-activated
hand-supportable bar code symbol readers are now able to accurately read, in an
unprecedented manner, bar code symbols on bar code menus, consumer products positioned
in crowded point-of-sale environments, and other objects requiring automatic identification
and/or information access.
