A sheet sorting apparatus includes a second tray arranged below a first tray detachable from a main body having a first discharge port corresponding to the first tray and a second discharge port corresponding to the second tray, a discharge unit, a tray detecting unit, and a control unit. The discharge unit discharges a sheet toward the first or second discharge port. In a state that the first tray is detached from the main body and the discharge unit discharges sheets from the first discharge port to the second tray and then the first tray is detected as attached to the main body, the control unit selects a discharge destination of a second sheet, subsequent to a first sheet discharged and stacked first after the first tray is attached to the main body, such that the second sheet is stacked on a tray having the first sheet thereon.

Provided is an image forming system capable of reliably preventing others from removing and taking printed matter even though printing is executed beforehand. The confidential notation reading unit reads a confidential notation. The user storage tray has a structure from which outputted printed matter cannot be removed unless the opening/closing door is opened. The locking mechanism locks the opening/closing door. The sorting mechanism sorts the printed matter outputted from the image forming apparatus and outputs the printed matter to either the open tray or the user storage tray. The sorting control unit outputs printed matter to which a confidential notation is not added to the open tray, and outputs a printed matter to which a confidential notation is added to the user storage tray, respectively.

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 sheet processing apparatus has: a processing unit having, at a front side of a housing, openings through which at least one of feeding a sheet in the housing or feeding the sheet out from the housing is performed; a storage chamber configured to store the sheet fed in the housing, and a door disposed at an opening part of the storage chamber is capable of being locked; a control unit configured to control transport of the sheet between a container, the openings and the storage chamber, the container configured to be capable of being detachably mounted to the processing unit or the storage chamber and configured to be stored the sheet fed in the sheet processing apparatus; and an attachment unit provided at the back side of the processing unit or on the back side of an outer surface of the storage chamber, the attachment unit to which the container is capable of being mounted.

A recording apparatus includes a recording portion configured to record an image on a recording medium; a housing having an ejection opening on the side of the housing, the recording medium recorded image being ejected from the ejection opening in the ejection direction; and a receiver that receives the recording medium ejected from the ejection opening. The recording apparatus includes a first guide provided inside the ejection opening of the housing, and the receiver has a first end being on an upstream side of the receiver in the ejection direction such that the end is held at a position overlapping with the first guide.
