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).

When a discharge count has exceeded a specified number of sheets, a sheet discharge device executes a process of moving down a discharge tray by a specified quantity and thereafter moving up the discharge tray until a top-surface detection part outputs a top-surface detection signal, while clocking a move-up time lasting from a move-up start of the discharge tray until output of the top-surface detection signal by the top-surface detection part. When the move-up time is equal to or less than a reference time, the sheet discharge device makes a next sheet discharged while the top-surface detection part outputs the top-surface detection signal; on the other hand, when the move-up time is more than the reference time, the sheet discharge device executes a correction process of moving down the discharge tray before making the next sheet discharged.

A sheet processing apparatus including a table to be loaded a first and a second banknote group partitioned by a header card recording the bar code number in the piling direction of the banknotes, a take-in portion to take in the banknotes of the first and second banknote groups loaded on the table and the header card, a discrimination portion to count the banknotes taken in by the take-in portion and discriminate the kind thereof, a plurality of stackers to sort and stack the banknotes discriminated by the discrimination portion on the basis of the kink thereof, and a sensor to detect the header card taken in by the take-in portion. The sheet processing apparatus additionally includes a controller to control so as to stop the taking-in of the second banknote group on the basis of detection of the header card by the sensor and after a lapse of a predetermined time, to start the taking-in of the second banknote group.

According to an embodiment, a decoloring device is disclosed. A decoloring unit decolors an image formed with decolorable colorant on a sheet. A reading unit reads a surface of the sheet to determine whether the surface of the sheet is reusable. When the surface of the sheet read by the reading unit is determined to be not reusable, a marking unit adds a mark to the read surface. A first tray receives the sheet on which a mark is added by the marking unit.

Provided is a paper sheet processing apparatus capable of distinguishing a counterfeit bill or a paper sheet suspicious to be a counterfeit bill from bills inserted through an insertion slot to stop a wrongdoing. A storage unit stores information on a paper sheet read by a bill reader and a verification unit verifies the paper sheet using the information on the paper sheet stored in the storage unit. If the paper sheet is determined to be counterfeit in the verification, a conveyance unit conveys the paper sheet toward the insertion slot. A comparison unit compares the image data of the inserted paper sheet with image data of a previously inserted paper sheet and if the image data of the inserted paper sheet is determined to be identical to the image data of the previously inserted paper sheet in the comparison, a control unit sends a signal to a host apparatus.

Provided is a paper sheet processing system capable of collecting a wrong paper sheet put in a bill processing apparatus to examine the collected paper sheet without making the supplier feel doubt. A paper sheet processing apparatus verifies a paper sheet using image data acquired by a bill reader when the bill is being conveyed. If the paper sheet is determined to be counterfeit in the verification, the paper sheet processing apparatus holds the paper sheet within the paper sheet processing apparatus and sends a signal from a controller of the paper sheet processing apparatus to instruct a report device to report a result different from the result of the verification. The report device reports a result irrelevant to use of a wrong paper sheet.
