Abstract: This paper sheet processing device (100) for processing paper sheets is provided with: an identification unit (55) for identifying paper sheets; stacking units (60, 210) for stacking paper sheets on the basis of the content of classification types identified by the identification unit (55); and a control unit (50, 135, 550) that reads, from a memory unit (56, 136, 560) in which an upper limit of paper sheets to be stacked by the stacking units (60, 210) are stored in association with the content of classification types, the upper limit for paper sheets that correspond to the content of the classification types of the paper sheets stacked by the stacking units (60, 210), and sets the upper limit for paper sheets to be stacked by the stacking units (60, 210).

Abstract: A banknote recognition apparatus (220) for recognizing a type of a banknote includes: a detection unit configured to detect the banknote to be recognized; an evaluation-value calculation unit (30) configured to calculate each evaluation value of the banknote, by using one evaluation-value-calculation-formula set composed of a combination of a plurality of predetermined evaluation-value calculation formulae, based on a detection result obtained by the detection unit; and a recognition unit (32) for recognizing the type of the banknote, by using a plurality of predetermined threshold values respectively corresponding to each type of banknote, based on each evaluation value of the banknote calculated by the evaluation-value calculation unit (30).
