LASER SCANNING SYSTEM FOR READING BAR CODES ABSTRACT OF THE DISCLOSURE A laser-scan bar code reader is mounted in a hand-held unit operable in two modes. In one mode the hand-held unit may be mounted in a fixed position in a terminal, in which case the data generated from the bar code reading operation is transferred immediately to the terminal and the reader is powered continuously from the terminal unit. In the other mode, the hand-held unit is separated from the terminal and held manually, in which case the data from bar code reading is stored in a local memory to be later transferred to the terminal when the hand-held unit is again inserted into the terminal. A battery in the hand-held unit is charged when the unit is mounted in the terminal, then powers the hand-held unit while operating remote from the terminal. The power for battery charging and the data transfer are accomplished without direct connections between the hand-held unit and the terminal. 18
