ABSTRACT:
A hands-free scanning system for reading indicia having parts of different light reflectivity, including a housing having a window and an actuatable electro-optical scanner in the housing for projecting a light beam through the window to indicia to be read, for scanning the indicia. The system further detects light of variable intensity that is reflected off the indicia to generate an electrical signal representative of the indicia. The housing is mounted on an arm of an operator and the scanner initiates reading of the indicia upon movement of the operator's hand relative to the arm by means of an actuator switch.
