| abstract |
A portable hand-held device (10) for data collection by an operator includes a grip unit (12) having polarized connectors (31, 32) at the top and bottom thereof for removable engagement with mating polarized connectors (33, 34) in external modulus (14) furnishing operator selectable, application functions such as CCD or laser scanning, and radio frequency automatic identification. Device (10) is held and operable by one hand in either right- or left-handed configurations with the output from modules (14) directed away from the operator and toward the object from which data is to be obtained. The connectors (31, 32) are mounted in reversed orientation from each other, thereby insuring that external removable modules (14) are automatically connected in the proper orientation for the desired handed operation. |
