ABSTRACT:
A hand held character scanning system is provided in which logic circuits are responsive to the generation of digitized data signals representing the character scanned together with the background area adjacent the character to determine if the data signals represent the scanning of a complete character. The signals are also used to determine the directions of scan together with raising an interrupt signal to a processor which performs a recognition operation on the data signals generated.
