Abstract

PURPOSE: To secure a high-accuracy collation between the pattern of the paper sheet and the registered pattern by selecting one of the characteristics extractor circuits in accordance with the code information read out from the magnetic head and then comparing the output of the selected extractor circuit with the pattern information read out from the file memory.
CONSTITUTION: Magnetic head 3 reads out the code information from the paper sheet on which the code information and the proof pattern are recorded, and optical head 10 reads out the proof pattern. On the other hand, file memory 9 memorizes the pattern information whose characteristics are extracted from the proof pattern registered previously on the code information. Characteristics extractor circuits 7-1W7-N extract the characteristics from head 10, and one of circuits 7-1W7-N is selected according to the code information read out at code reading part 4. And the output of the selected circuit is compared and collated (12) with the pattern information read out from memory 9. As a result, an automatic and high-accuracy collation is ensured between the pattern on the paper sheet and the pattern registered previously.
