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.

A medium placement device configured to have a medium discharged from a discharge unit of a processing device placed therein, and includes: a placement unit including a plurality of placement surfaces, with different angles with respect to a horizontal direction, that are disposed along a discharge direction of the medium, the placement unit being configured to have the medium discharged from the discharge unit placed thereon; and a plurality of restricting members disposed facing the placement unit along the discharge direction, the plurality of restricting members being configured to come into contact with the medium from above. In an initial state in which the medium is not placed, a distance in a gravitational direction between a first end of each of the plurality of restricting members on a placement unit side and one of the plurality of placement surfaces that faces the first end in the gravitational direction is constant.

A medium receiving tray has a first tray and a second tray. A movable support having a second support surface for supporting media is disposed in the second tray. When the medium receiving tray is in a first state, the movable support is positioned above a first support surface of the first tray. When the medium receiving tray is switched from the first state to a second state, a free end is detached from the downstream end of the first support surface and displaced downward, and the second support surface is thereby inclined upward toward the downstream in a medium discharging direction.

A sheet feeding device includes a storage, a discharger, an angle adjuster, and an urging body. The storage stores a sheet bundle. The discharger contacts and discharge an uppermost sheet of the sheet bundle from the storage in a sheet conveying direction in which the uppermost sheet is conveyed. The angle adjuster changes an angle according to a remaining amount of the sheet bundle in the storage. The urging body urges a trailing end of the uppermost sheet in the sheet conveying direction toward the discharger in stages according to the remaining amount.

A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to discharge the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged facing the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located at a downstream end of the stacking portion and a downstream end of the passage forming portion in a conveying direction of the print medium. The passage forming portion includes an opening/closing portion which is displaceable between a closed position for forming the discharge passage and an open position for opening access to the stacking portion.

An image forming apparatus includes a discharge tray, a sheet contact plate, an arm, a slider, and a spring. The sheet contact plate includes a first end portion and a second end portion located downstream in a sheet discharge direction and is pivotable about a first axis located at the first end portion between a retracted position and a protruding position. The arm includes a third end portion and a fourth end portion. The third end portion is supported by the second end portion of the sheet contact plate such that the arm is pivotable about a second axis located at the third end portion. The slider supports the fourth end portion of the arm such that the arm is pivotable about a third axis located at the fourth end portion. The spring urges the slider away from the first axis along the sheet discharge direction.

A recording apparatus includes: an output tray into which the paper sheet on which recording has been performed is outputted, wherein the output tray has a rib—includes a pair of first ribs disposed at an upstream position, the pair of first ribs being elongated in an output direction and protruding, and a pair of second ribs disposed at a downstream position, the pair of second ribs being elongated in the output direction and protruding, the output tray has an upstanding end portion (edge receiving section) formed at a downstream end in the output direction, the second rib is formed to be continuous from the edge receiving section, and each of the pair of first ribs and the pair of second ribs are symmetrically arranged to a center (center line) in a width direction, which is perpendicular to the output direction of the paper sheet.

An image forming apparatus includes a paper discharging tray and a paper detection part disposed at an upstream end of the paper discharging tray in a paper discharge direction. The paper detection part includes a base end member provided rotatably around a first axis extending in a direction perpendicular to a paper discharge direction and a tip member pivoted to the base end member to rotate around a second axis parallel to the first axis, and extending downwardly to incline toward an upstream side of the paper discharge direction in a state where the base end member is not subjected to pressure from the paper being discharged. The base end member is disposed to face a discharge opening when being at the reference position, and the image forming apparatus stops discharging paper from the discharge opening when the base end member rotates by a predetermined threshold or more with respect to the reference position.

A recording device includes a recording unit configured to perform recording on a medium, and a discharge tray located above the recording unit in a height direction of the recording device and configured to support the medium discharged after recording is performed thereon, and a flow path of air for cooling a cooling target is formed along a lower surface of the discharge tray. The recording unit is an example of the cooling target.

An article supporter for a supply device includes a feeder that supplies, by air suction, an uppermost thinly tabular article from a bundle of a plurality of thinly tabular articles that is stacked and is partially different in thickness, the article supporter for supporting the bundle with a gap between the uppermost thinly tabular article and the feeder, and the article supporter includes: a first support that supports respective thinner parts of the plurality of thinly tabular articles; a second support that supports respective thicker parts of the plurality of thinly tabular articles and is movable upward and downward; and an adjuster that adjusts a level of the second support such that the uppermost thinly tabular article of the bundle is set within a predetermined range in a vertical direction.
