Abstract
Disclosed is an automatically-activated code symbol reading system comprising a code symbol reading mechanism contained within a hand-supportable housing having a manually-actuatable data transmission switch. The symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more code symbols on an object during each symbol reading cycle, and automatically generating a new symbol character data string in response to each read symbol. The user visually aligns the laser scanning pattern with a code symbol on an object. Each time the scanned symbol is successfully read in a cyclical manner, a new symbol character string is produced, and an indicator light is actively driven. During the symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a subsequently produced symbol character data string to be automatically selected and transmitted to the host system.
