Abstract
A portable hand-supportable data terminal for allowing an operator to enter, collect, and display data. The data terminal comprises a hand-supportable housing having a light transmission aperture and an automatically-activated bar code symbol reading subsystem integrated therewithin. The bar code symbol reading subsystem includes a bar code symbol reading mechanism. Each instant a bar code symbol is read within a predetermined time period, a symbol character data string representative of the read bar code symbol is automatically produced. A manually-activatable data transmission switch generates a data transmission control activation signal in response to the activation of the switch. A system controller controls a data transmission circuit so that the symbol character data string, produced at substantially the same time when the data transmission control activation signal is generated, is transmitted to a data storage device aboard the data terminal or to a host system in communication therewith.
