Abstract
A bill identification apparatus which is hardly subject to decision errors attributable to fluctuations of detected data caused by aging or partial soiling of bills. In identifying a bill, physical properties pi for various positions i on the bill are detected in synchronism with the transportation speed of the bill, a correction value pm for making an average value for an inspection section for the detected data pi equal to an average value for an inspection section for standard pattern values pci is obtained, and the detected data pi are corrected by using the correction value pm, thereby eliminating fluctuations of the data attributable to general deterioration or soiling of the bill or detectors. Also, the authenticity and type of the bill are discriminated by computing a heterogeneity pr on the basis of a statistical synthetic evaluation of the correlation between the standard pattern value pci and the detected data pi for each position i, whereby wrong classification and authentication attributable to partial data errors can be prevented.
