Abstract: A banknote storage includes a memory unit that stores therein number-of-sheets information for banknotes stored in the banknote storage by denomination being a kind of the banknotes and by category being a classification based on a feature amount of the banknotes. Categories represent classifications when the banknotes are classified by their features. In five classifications defined by ECB, the banknote is classified into two depending on whether the banknote is genuine or counterfeit, and the former is called a genuine note and the latter is called a rejected note. The genuine note is further classified into two depending on how the genuine note is damaged, and one of them without any trouble in its usage is called a fit note and the other one with any trouble assumed in its usage because of being largely damaged is called an unfit note.
