ABSTRACT:
A system for scanning a bar code label includes a light source for projecting light beams at the label, a rotating disc member located in a path of the reflected light beams, an array of charge-coupled devices mounted on the disc member for storing electrical signals upon sensing the reflected light beams, circuit means mounted on the disc member for reading and processing the electrical signals, a plurality of light-emitting diodes mounted on the rotating disc member for outputting binary signals representing the electrical signals stored by the array, and a photodiode mounted adjacent the rotating disc member for reading the output of the light-emitting diodes for transferring the data to a central processor for processing the data.
