  • means for reading patterns from the conveyed bill;

    one or more sensors, operatively connected to said means for reading patterns, for determining the conveyance condition of the bill;

    means, operatively connected to said one or more sensors, for generating the standard patterns corresponding to the conveyance condition of the bill and the denomination of the bill by dividing a predetermined area of the bill into sections, said means comprising;

    a model map memory for storing the standard patterns provided by said means for generating the standard patterns; and

    zone address-selecting means, operatively connected to said model map memory, for supplying address data to said model map memory in order to read out the standard patterns corresponding to the conveyance condition of the bill and denomination of the bill, said zone address-selecting means generating said address data in dependence upon information concerning the conveyance condition of the bill, including the amount of tilt of the bill, information regarding the width of the bill, deviation of the bill in the passage in the direction of a line perpendicular to the direction of the conveyance of the bill, the conveyance speed of the bill, and the denomination of the bill; and
