A medium ejection apparatus includes a placement mount on which media are placed, a restriction part that moves between a restriction position at which the restriction part restricts media ejected toward the placement mount and a retracted position retracted from the restriction position, and a processor that controls the restriction part by adjusting a restriction frequency on the basis of at least either an amount of movement of the restriction part from the retracted position to the restriction position or ejection intervals at which the media are ejected toward the placement mount, the restriction frequency being a frequency with which the restriction part performs a restriction operation for the media.

A recording apparatus includes a recording unit configured to record an image on a recording medium, a discharge unit, a tray, and a side portion. The discharge unit discharges the recording medium in a discharge direction. The recording medium discharged by the discharge unit is stacked on the tray. The side portion regulates the recording medium stacked on the tray in a direction intersecting the discharge direction. The side portion is provided with an exhaust vent hole including an inclined portion for upwardly exhausting air from an inside of the recording apparatus to an outside of the recording apparatus.

A paper ejection device includes: an ejection portion that ejects sheets of paper; a housing portion that houses the ejected sheets of paper in a sequentially stacked state; and a guiding portion that guides the sheets of paper, before being ejected, to the ejection portion while curving the sheets of paper. The housing portion is adjustable to plural angles including at least an angle at which the ejected sheets of paper are housed while being curved in a direction opposite to a direction in which the sheets of paper have been curved by the guiding portion.

A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part (100) being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer (142) which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part (100) has a coil antenna (104c) which wirelessly receives the information transmitted from the reader/writer (142), and a storage part (104b) which stores the information on the bill received from the coil antenna (104c).

A cutting apparatus includes a blade configured to cut a sheet that is conveyed along a sheet conveyance path, a scrap path through which scrap generated when the sheet is cut by the blade passes, a guide member configured to guide the sheet conveyed, and a blowing unit configured to blow air such that the air crosses the sheet conveyance path from a side opposite the scrap path with the sheet conveyance path therebetween, wherein the blowing unit blows air such that the air flows along the guide member positioned at a second position at which the scrap is allowed to enter the scrap path.
