Some examples of a document scanning system can include a scanner and a sheet output stacker. The stacker includes an upper surface configured to mate with the scanner configured to scan and transfer contents of a paper document. The stacker is configured to receive paper sheets from the scanner. The stacker includes multiple, upward extending interface housings positioned on the upper surface. The multiple interface housings are configured to be received in respective multiple receiving structures in the scanner, and are configured to mechanically and electrically couple the sheet output stacker and the scanner. The interface housings allow care-free electrical and mechanical pairing of a scanner to a stacker with no tools or adjustments. Simply positioning the scanner on the stacker such that the interface housings are aligned with the receiving structures results in the scanner being automatically guided into place and connected to the stacker through gravity.

A sheet stacking tray includes a first conveyor, a second conveyor, a sheet stopper, a first full-load detector, a second full-load detector, and a plurality of motors. The plurality of motors maintain the sheet stopper at a protruding position to block a sheet conveyed by the first conveyor until the first full-load detector outputs a signal indicating that a sheet bundle is fully loaded, shift the sheet stopper to a lowered position to allow the sheet bundle to pass when the first full-load detector outputs the signal indicating that the sheet bundle is fully loaded, drive the first conveyor and the second conveyor together to convey the sheet bundle when the sheet stopper shifts to the lowered position, and stop the second conveyor and drive only the first conveyor, when the second full-load detector detects a leading edge of the sheet bundle.

The present invention provides a medium processing device and medium transaction device that may increase stability by shortening a conveyance path. Namely, a banknote deposit/withdrawal device includes a conveyance section that forms a linear conveyance path along a front-rear direction inside an upper section block, in the vicinity of a boundary with a lower section block. An upper section storage box is disposed in the vicinity of a rear side terminal end of a rear conveyance section. Counterfeit notes are conveyed to the upper section storage box using a switching section. Accordingly, due to keeping the conveyance path length short, the banknote deposit/withdrawal device may reduce the frequency of occurrence of faults, such as banknote jams, and may prevent the circulation of counterfeit notes by storing counterfeit notes segregated from genuine banknotes, reject banknotes, and the like.

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).

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.
