Provided are an imaging unit capable of imaging a banknote processing device and a periphery of a transaction operation clerk who is operating the banknote processing device and a recording unit that records imaging data of the imaging unit, an identification number that is visually identifiable is inscribed on at least one surface of a partition card, the imaging unit is capable of imaging the identification number, and the recording unit records imaging data of the imaging.

A paper sheet processing device includes: a charging inlet that takes in paper sheets in a conveyance direction, the paper sheets including at least one target sheet and a partition card overlapped on the target sheet, the partition card having a main surface portion having at least one identification hole group, the identification hole group having at least two through holes arranged along the conveyance direction; a detection unit that detects take-in of the paper sheets by the charging unit, and detects the identification hole group; and a control unit that determines a paper sheet is the partition card in a case where the identification hole group has been detected by the detection unit, and determines that a paper sheet is the target sheet in a case where the identification hole group has not been detected by the detection unit.

A post-processing apparatus includes: a cutter that cuts a paper sheet into a plurality of pieces; and a hardware processor that causes the cutter to cut out a product formed in part of the paper sheet and a partition sheet formed in another part of the paper sheet, wherein the hardware processor causes the partition sheet and the product to be ejected to the same ejection destination at timings different from each other, and the partition sheet is formed between jobs that cause the product to be generated.

A printing apparatus includes a drying unit that dries a medium, a controller that controls to output a partition sheet as a partition of the medium on which printing based on a print job has been performed, and a liquid application unit that applies liquid onto the partition sheet.
