B-6268 BAR CODE CONVERTER ABSTRACT OF THE DISCLOSURE Bar codes imprinted or otherwise applied to an object are read and decoded by focusing light reflected from the code by means of an object lens to a light responsive transducer. Electrical signals produced by the transducer are correlated and converted from a trinary code format into a binary code format. The trinary code utilizes bars and half bars made up of segments in one or more of four quadrants to represent a decimal equivalent number. This trinary code is applied to a converter where logic converts the trinary signals into equiva- lent binary signals which are then translated from a serial format into a parallel format for further processing by con- ventional binary code processors.
