However, in the above-mentioned bill handling apparatus, two kinds of bills having different handling conditions (for example, a confirmed bill and an undecided bill, a normal bill and a reject bill) are superposed through a partition member. In such a situation, it may be difficult to detect bills using the photosensor. In other words, when it is not necessary to distinguish between the two types of banknotes, it is possible to detect the presence / absence of the two types of banknotes with the photo sensor, but it is impossible to detect the presence / absence of only one of the banknotes. Was.

Therefore, conventionally, a counting process is always performed when a bill is moved in the apparatus, and the presence or absence of a bill at a predetermined position is determined based on the counting process result. There was a possibility of misidentifying the presence or absence of a bill due to counting errors.
