紙葉類識別装置及び識別方法
Document Type and Number:
Japanese Patent JP4634073
Kind Code:
B2
Abstract:
A method for discriminating paper-like sheets comprises an authenticity judgment step. The authenticity judgment step includes a pattern detection step for irradiating infrared light on predetermined irradiation lines X in a direction along which the paper-like sheet M is to be inserted with a predetermined interval to detect a pattern of amounts of transmitted light on the predetermined irradiation lines X; an arithmetic processing step for comparing the pattern of amounts of transmitted light obtained by the pattern detection step with a pattern of amounts of transmitted light which has been previously obtained from a genuine paper-like sheet MA by means of the pattern detection step to standardize data, thereby obtaining standard values S at the respective irradiation points P of the paper-like sheet M inserted; and a judgment step for comparing the standard values S with the maximum standard value Tmax of the genuine paper-like sheet MA which has been previously obtained, thereby to judge the paper-like sheet M as a counterfeit note when the number of the standard values S each of which is larger than the maximum standard value Tmax reaches a predetermined number.
