A sheet conveying device includes: a housing; a sheet supply tray; and a dust proof cover including a first cover and a second cover. The sheet supply tray is supported to the housing and pivotally movable between a closed position and an open position. The first cover is supported to the housing and pivotally movable between a first position in proximity to the sheet supply tray and a second position away from the sheet supply tray. The second cover is connected to the first cover and pivotally movable about a second pivot axis between a third position in proximity to the sheet supply tray and a fourth position away from the sheet supply tray. The second cover has a center of gravity positioned closer to the housing than the second pivot axis is to the housing in a state where the sheet supply tray is in the closed position.

A medium feeder includes a medium mounter, a pair of edge guides, and a sheet number limiter. The medium mounter has a mounting surface on which a medium to be fed is placed. The pair of edge guides is provided at the medium mounter to guide side edges of the medium in a direction that intersects with a feeding direction in which the medium is fed. The sheet number limiter is provided at the pair of edge guides to limit the number of media mountable on the medium mounter. The sheet number limiter has an extension that extends in a feeding direction of the medium such that a distance between the extension and the mounting surface increases downstream.

A pair of edge guides provided on a medium mounting section of a medium feeding apparatus each include a volume limiter spaced from the mounting surface of the medium mounting section and extending from the guide surface of at least one of the pair of edge guides in a direction intersecting the guide surface, the volume limiter including a limiting surface that limits a number of sheets mounted on the medium mounting section. The limiting surface includes a groove extending in the feed direction, at a position between a corner portion formed at an intersection of an end portion of the limiting surface in the width direction and the guide surface, and the other end portion of the limiting surface, and configured to insert at least a part of a side edge of the medium, to thereby restrict the side edge from moving in the width direction.

A medium housing device includes: a frame including an internal space; a partitioning plate that partitions the internal space so as to intersect with a specific collection direction, and that forms a collection space in which the medium is collected along the collection direction; a partitioning plate moving section that moves the partitioning plate along the collection direction; a side guide that is attached inside the frame and that determines the size of the collection space in an intersecting direction intersecting with the collection direction; a positioning portion that positions an end portion of the side guide at one attachment position selected from a plurality of attachment positions; and a retention switching portion that switches between a retained state in which the end portion of the side guide is positioned, and a retention-released state in which the end portion of the side guide is not positioned.

An automatic stack feeder having a moveable stack or product guide is disclosed. The automatic stack feeder may be configured to receive a stack of articles and a container enclosing a stack of articles. To ensure the stack of articles is properly supported following unloading from the container, the stack guide is moveable between a first and a second position, wherein the stack guide is in contact with the stack of articles while in the first position, and not in contact with the stack when in the second position.

A cash automatic transaction device capable of, upon storage of a banknote sent from a depositing/dispensing port in a banknote storage box, or upon accumulation of a banknote sent from the banknote storage box in the depositing/dispensing port, preventing the occurrence of trouble such as paper jam or poor posture. The cash automatic transaction device has a depositing/dispensing port used for depositing/dispensing of banknotes, and a banknote storage box for storage of deposited/dispensed banknotes. The depositing/dispensing port has depositing/dispensing space to store the deposited/dispensed banknotes, and accumulation space in which the banknote is accumulated upon dispensing. The width of the depositing/dispensing space is smaller than the exit and entrance width of the storage box, while the width of the accumulation space is greater than the exit and entrance width of the storage box.

A tapping device includes a contact unit that comes into contact with a medium from one side of a crossing direction that crosses a transport direction of the medium; an approaching and separation unit that approaches and is separated from the contact unit in the crossing direction; and a displacement unit that is supported by the approaching and separation unit via a bias unit, at each of positions shifted from each other in the transport direction to be displaceable in the crossing direction, and taps the medium in contact with the contact unit from the other side of the crossing direction by the approaching and separation unit approaching the contact unit.
