A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

A first tray is capable of stacking a sheet discharged from a discharge port of a printing apparatus. A second tray is accommodated in a lower side of the first tray and is capable of stacking the sheet discharged from the discharge port by being drawn out in a sheet discharging direction from the discharge port. A changing unit changes inclination angles of the first tray and the second tray with respect to the sheet discharging direction according to a drawn-out position of the second tray.

A sheet conveyance apparatus includes: a supply-sheet supporter having a supply support surface that supports a sheet; a conveyor configured to convey the sheet from the supply-sheet supporter along a conveyance path; and a discharged-sheet supporter disposed above the supply-sheet supporter and configured to support the sheet conveyed by the conveyor. The discharged-sheet supporter includes: a particular end portion located farthest from the conveyor in the discharged-sheet supporter and opposed to the supply support surface from above; and a movable member including the particular end portion at one of opposite end portions of the movable member, which one is farther from the conveyor than another of the opposite end portions. The movable member is pivotable in a direction in which a distance between the particular end portion and the supply support surface is increased.

A paper output tray includes: a tray main body where sheets discharged from an apparatus main body are stacked; a first extension tray which is to be housed in the tray main body on a lower surface side thereof so as to be pullable forward from a front end of the tray main body; and a second extension tray which is rotatably supported by the first extension tray and is expandable from a closed state, in which the second extension tray is folded on the upper surface of the first extension tray, to an open state in which the second extension tray extends forward of the first extension tray. The first extension tray has a support portion extending downward from the upper surface where the sheets are stacked, and the second extension tray is rotatably supported by the support portion.

An image forming apparatus includes a stopper member supported either in a storage posture stored in a storage part by turning in an upstream side or a restriction posture to prevent falling down of a sheet from a sheet stacking face by turning in a downstream side. The storage part has a first recess and a second recess deeper than the first recess. The stopper member has a pressed part supported in the second recess movably upward and downward and a main part supported in the first recess in the storage posture. When the pressed part is pressed downward in the storage posture, the pressed part is moved downward and the main part comes into contact with a downstream side edge of the first recess, the stopper member is turned around the downstream side edge into the restriction posture through a protrusion posture protruding above the sheet stacking face.

A medium ejection apparatus includes an ejection tray having a first stacking surface, and an extension tray rotatably attached to an end part of the ejection tray at a downstream side in a medium ejection direction, and having a second stacking surface. An end part of the ejection tray at the downstream side is provided with a first abutting part and a second abutting part. An end part of the extension tray at the ejection tray side is provided with a first abutted part and a second abutted part. The second stacking surface is located forming a first angle with respect to the first stacking surface by the first abutted part abutting against the first abutting part. The second stacking surface is located forming a second angle, different from the first angle, with respect to the first stacking surface by the second abutted part abutting against the first abutting part.

There is provided a sheet tray including: first, second and third trays. The second tray moves between a first position and a second position in which an overlapping area is smaller than that obtained in the first position. The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

A sheet feeding device includes a document mounting board, in which a downstream end of the document mounting board in the feeding direction of the documents in the feed mechanism is connected to a scanner body so as to be rotatable about a first turning shaft parallel to a rotation shaft of a pickup roller, the first turning shaft is located downstream from the feed mechanism in the feeding direction of the documents in the feed mechanism, a mounting surface of the document mounting board on which the documents are mounted is located above the pickup roller when the documents are mounted on the document mounting board, and the document mounting board turns about the first turning shaft such that the mounting surface moves downward and the mounting surface moves downward from a contact portion of the pickup roller with the document when the documents mounted on the document mounting board are fed.

A sheet discharge apparatus includes a main tray, a discharge unit, and an expansion tray. The main tray is pivotable between a closed position and open position relative to a sheet discharge apparatus main body. The discharge unit discharges the sheet onto the main tray in the closed position. The expansion tray expands a main tray stacking area and is movable between a storage position where the expansion tray is stored in the main tray and an expansion position where the expansion tray is slid from the storage position in a sheet discharge direction and expands the stacking area. At the expansion position, the expansion tray is pivotable independently of the main tray. A direction in which the expansion tray is pivoted upward is the same as a direction in which the main tray is pivoted from the closed to the opened position.

A paper output tray includes: a tray main body where sheets discharged from an apparatus main body are stacked; a first extension tray which is to be housed in the tray main body on a lower surface side thereof so as to be pullable forward from a front end of the tray main body; and a second extension tray which is rotatably supported by the first extension tray and is expandable from a closed state, in which the second extension tray is folded on the upper surface of the first extension tray, to an open state in which the second extension tray extends forward of the first extension tray. The first extension tray has a support portion extending downward from the upper surface where the sheets are stacked, and the second extension tray is rotatably supported by the support portion.
