Abstract:
A bar code reader for reading information encoded in a bar code, said reader comprising:a) a gun-shaped housing;b) a focusing system located within said housing, said focusing system including:i) a single focusing source for producing a focusing beam; andii) a beam modifying optics for modifying said focusing beam and producing a focusing pattern for assisting an operator in determining a proper relative position between said reader and said bar code;c) an illumination system located within said housing for flood illuminating said bar code;d) a detection system located within said housing and being optically isolated from said illumination system, said detection system for detecting an optical image of said illuminated bar code and converting said optical image into a corresponding set of electrical signals,e) a processor located within said housing for processing said set of electrical signals; andf) a trigger for enabling focusing system, said illumination system, said detection system and said processor.
