SO-2-23355M/KH/80 ABSTRACT OF THE DISCLOSURE An optical character reading system in which a sheet upon which characters or symbols are printed is illuminated and the characters scanned with a two-dimensional photoelectric sen- sor. Output signals from the sensors are processed to read the characters through right and left frame detecting circuits, The right and left frame detecting circuits detect white/black pat- terns of frames formed on the sensor when the left and right sides of the characters extend beyond the ends of the ranges of the sensor, A circuit combines the white/black patterns detected by the right and left frame detecting circuits to provide a recognition of the characters being scanned.
