Abstract

PURPOSE:To improve the rate of recognition by increasing a noise margin with simple constitution by converting magnetized information from a single magnetic read head into a digital signal directly and by making a trigger for a synchronizing signal at the time of maximum amplitude of polarity N appearing first in the magnetized information. CONSTITUTION:A document on which magenetic ink characters prescribed to E13B are printed is scanned by scanning mechanism 1 and its magnetic ink characters are magnetized by DC magnetizing head 2. Read head 3 is arranged at the rear of the scan to detect the magnetized state of the magnetic ink characters, and the output of head 3 is amplified by amplifier 4, whose output is inputted to S-pole-side detector 5 and N-pole-side detector 6. To timing generating circuit 7, synchronizing signal A of each character obtained by detector 6 and scan signal B that corresponds to the extent of the scan from scanning mechanism 1 are inputted to input sampling signal C, which correspond to sampling points character to character, to detector 5. Then, S-pole-magnetized information D from detector 5 is applied to memory circuit 8 to improve the recognition of discriminator 9.
