Abstract
A bill discriminating device which is able to carry out a bill discriminating operation at high speed and precision based on a reduced amount of processing data for bill-type discrimination by extracting and reading only characteristic regions of the bill. According to the present invention, bill discrimination can be carried out by: reading the picture image data output from an image sensor; roughly discriminating the type of bill from the length of the picture image data (corresponding to the width of the bill); reading position data and reference patterns of the characteristic regions corresponding to the type of bill; extracting picture image data (a characteristic pattern) corresponding to the characteristic regions from the position data; and, finally discriminating the type of bill by comparing the characteristic patterns with the reference patterns.
