A sheet sorting apparatus comprising a first tray, a second tray, a conveyance unit, a tray detection unit, a stacking amount detection unit, and a control unit configured to control the conveyance unit to not convey the sheet to the second tray, in a case where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount, wherein the control unit is configured to permit the conveyance unit to convey the sheet to the second tray, in a case where the tray detection unit detects that the first tray is detached from the apparatus main body in a state where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount and conveyance of the sheet to the second tray by the conveyance unit is stopped.

A medium storage device includes: a safe having, at a rear portion, an entrance for replenishment and recovery to which a transit cassette is connectable; an identification unit serving to identify whether a medium is a normal medium or a rejection medium; a temporary holding unit configured to temporarily accommodate a medium; a recycle cassette configured to accommodate the medium identified as the normal medium; a conveyance path configured to convey the medium between the identification unit, the temporary holding unit, and the recycle cassette; a control unit configured to control the conveyance path such that the medium replenished from the transit cassette is conveyed to the temporary holding unit, the medium conveyed to the temporary holding unit is conveyed to the identification unit, and the medium identified as the normal medium in the identification unit is conveyed to the recycle cassette.

A post-processing unit is disposed so as to face the apparatus side surface of a printer that has a manual feed tray protruding from the apparatus side surface. The post-processing unit has an ejection tray, which is movably provided in a unit body and to which paper accepted from the printer is ejected. In an apparatus height direction crossing a direction in which paper is ejected, the ejection tray can be moved to a first position at which ejected paper can be mounted and to a second position at which part of paper mounted on the manual feed tray can be supported.

A liquid ejecting apparatus includes a transport unit that transports a medium along a transport path, a liquid ejecting head that performs recording on the transported medium by ejecting liquid from a nozzle formed at a nozzle surface, a mounting portion on which a liquid storage portion for storing the liquid supplied to the liquid ejecting head is mounted, and a first discharge port that delivers the medium on which the recording is performed toward a media processing apparatus that performs processing on the medium, in which the mounting portion is disposed at a position higher than the nozzle surface, and a first transport path which is a portion of the transport path from a position corresponding to the liquid ejecting head to the first discharge port passes above the mounting portion.

A document sheet conveying device includes a slide cover. The slide cover is provided slidably between an open position for exposing the supply tray and the discharge tray and a closing position for covering the supply tray and the discharge tray. In addition, the slide cover includes a cover main body and a side cover. The cover main body is formed by connecting at least a top plate covering the supply tray and a front plate covering a front side of the discharge space when the slide cover is disposed at the closing position. The side cover is rotatably connected to a top surface side of the cover main body, covers one of right and left sides of the discharge space when the slide cover is disposed at the closing position.

A recording device as a processing device includes: a recording unit accommodated in a housing and configured to perform recording on a medium; and a medium accommodating unit that accommodates the medium discharged from the housing. The medium accommodating unit includes: a sheet-shaped accommodating member; a rotating shaft provided inside the housing and to which one end of the accommodating member is connected; and an operating portion provided separably from the housing and to which the other end of the accommodating member is connected. The accommodating member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing. The accommodating member is fed from the rotating shaft so that the medium is accommodated when the operating portion is separated from the housing.

A sheet sorting device includes three or more trays including a predetermined tray detachable from an apparatus main body and a tray different from the predetermined tray, a discharge unit to discharge a sheet to any one of the three or more trays, a control unit, and a tray detection unit to detect that the predetermined tray is detached from the apparatus main body. The control unit sets a sheet discharge destination such that a sheet conforming to a preset condition is discharged to the predetermined tray through the discharge unit. Where the tray detection unit detects that the predetermined tray is detached from the apparatus main body, the control unit sets a sheet discharge destination that has been set to the predetermined tray to the tray different from the predetermined tray based on a state of each of the trays other than the detached predetermined tray.
