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.

A conveying apparatus includes: receiving trays arranged vertically and has a lowest tray and a first receiving tray; a conveying mechanism; a supporter supporting the receiving trays; and a swing mechanism configured to swing the first receiving tray with respect to the supporter to one of a receiving position at which the first receiving tray receives a medium and an upper position. The swing mechanism is configured to: keep the first receiving tray at the upper position when a first external force directed in a direction in which the first receiving tray is moved from the upper position toward the receiving position is not applied to the first receiving tray located at the upper position; and swing the first receiving tray with respect to the supporter toward the receiving position when the first external force is applied to the first receiving tray.

A conveyor, including: receiving trays; a conveyance mechanism; and a support supporting the trays, wherein at least one tray except a lowermost tray is supported so as to be selectively positioned at one of a receiving position and an upper position, wherein at least one lower tray except an uppermost tray includes a protruding portion attached to a tray body so as to be selectively positioned at one of a protruding position and a retracted position, and wherein the conveyor includes a force transmitting mechanism for effectuating at least one of (a) a retracting movement of the protruding portion of one of the at least one lower tray from the protruding position to the retracted position caused by an upward movement of an adjacent upper tray disposed just above and immediately adjacent to the one of the at least one lower tray from the receiving position to the upper position.

A conveying apparatus includes: receiving trays including (i) a lowest tray, (ii) a first receiving tray different from the lowest tray, and (iii) at least one second receiving tray including one second receiving tray disposed just below the first receiving tray; a conveying mechanism; and a supporter supporting the receiving trays. The conveying apparatus further includes a transmission mechanism configured to perform at least one of: transmission of upward movement of the first receiving tray from a receiving position to an upper position, to downward movement of the one second receiving tray from the receiving position to a lower position; and transmission of the downward movement of the one second receiving tray to the upward movement of the first receiving tray.

A sorting device for articles has at least two main conveyor lines, each conveying consecutively arranged articles, at least two feeder devices, which respectively feed the articles to one of the main conveyor lines, at least two recognition devices for detecting a sorting destination for each article, a plurality of sorting outlets arranged at the end of each main conveyor line, each assigned to sorting destinations, and to which the articles are transported. The sorting device further has at least two connecting conveyor lines, each branching off the main conveyor lines at branch points, by way of which the articles can be conveyed from one main conveyor line to another main conveyor line. The articles can be temporarily stored in a storage device, which feeds temporarily stored articles to one of the main conveyor lines in the direction of conveyance before at least one of the branch points.

A stack state of a plurality of trays is collectively determined and is notified in steps. A printing apparatus includes an image forming unit configured to form an image on a sheet and create a printed material, a plurality of storage units each configured to store the printed material created by the image forming unit, a sorter unit configured to output the printed material to the plurality of storage units, and a determining unit configured to determine whether the plurality of storage units are in a nearly full state in which printed material is stored in almost all of the plurality of storage units.

An image forming apparatus includes a main body of the image forming apparatus with an opening portion, an image forming unit, an accommodation portion, a stack portion, a sheet moving unit, and a control unit that controls switching between a first mode that moves, with the sheet moving unit, a sheet accommodated in the accommodation portion and stops the sheet when a part of the sheet is exposed external to the main body of the image forming apparatus from the opening portion, and a second mode that moves the sheet, with the sheet moving unit, accommodated in the accommodation portion and that discharges the sheet to the stack portion.

A sheet sorting apparatus includes a first tray detachable from an apparatus main body, a second tray arranged below the first tray, a discharge unit to discharge a sheet to the first or second tray, a tray detecting unit to detect that the first tray is detached from the apparatus main body, a full stack detecting unit to detect a fully stacked condition of the first tray, and a control unit to control the discharge unit. In a case where the tray detecting unit detects that the first tray is detached from the apparatus main body, the control unit controls the discharge unit not to discharge a sheet to the second tray when a number of sheets discharged to the second tray reaches a threshold number of sheets, even though the full stack detecting unit does not detect the fully stacked condition.
