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.

A medium feeding device includes: a medium mounting section onto which a medium to be fed is mounted; a feeding unit that feeds the medium mounted on the medium mounting section; and a supporting member that supports an end in a width direction of the medium mounted on the medium mounting section and that supports the medium at a higher position than the medium mounting section in a direction of loading of the medium, the width direction being a direction crossing a feed direction.

A printing apparatus includes a tray on which a sheet is to be stacked, a container configured to store the tray such that the tray can be pulled out, a first guide unit configured to guide a slide of the tray in a pull-out direction, a second guide unit spaced apart from the first guide unit in a widthwise direction, a first regulating portion provided in the container and configured to regulate, by abutting against the tray, a tilt of the tray to one direction in the widthwise direction; and a second regulating portion provided in the container and configured to regulate, by abutting against the tray, a tilt of the tray to the other direction in the widthwise direction.

A medium ejecting apparatus includes a housing including an ejection port to eject a medium, a tray provided below the ejection port, to load the medium ejected from the ejection port, and a medium regulating member accommodated in the housing so as to be drawn out. The medium regulating member includes a medium contacting portion capable of regulating a position of a front end of the medium on the tray in a medium ejecting direction, a first supporting portion to support the medium contacting portion, and a second supporting portion to swingably support the first supporting portion.

An image forming apparatus includes a stacking tray, a control unit, an alignment member and a supporting mechanism. The control unit performs a rotational sorting. An alignment member includes a leading end wall coming into contact with a leading edge of a portrait sheet stack, a pair of first side walls coming into contact with both side edges of the portrait sheet stack and a leading edge of a landscape sheet stack, and a pair of second side walls coming into contact with both side edges of the landscape sheet stack and aligning the portrait sheet stack and the landscape sheet stack. The supporting mechanism supports the alignment member so as to be movable in an alignment position where the alignment member protrudes from an upper face of the stacking tray and in a retracting position where the alignment member retracts from the upper face of the stacking tray.

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 ribincludes 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.

A tray device includes a first tray including a first surface and an abutting portion, and a second tray including a second surface and an abutted portion. The second tray is configured to move with respect to the first tray. The abutting portion includes two abutting surfaces located obliquely with respect to an extending direction of the first surface. The abutted portion includes two abutted surfaces located obliquely with respect to an extending direction of the second surface. A difference between an angle formed by each of the two abutting surfaces and the extending direction of the first surface and an angle formed by each of the two abutted surfaces and the extending direction of the second surface is set larger than a maximum angular difference between the extending direction of the first surface and a movement direction in which the second tray moves with respect to the first tray.

A sheet transport device includes a transport unit, a load section, and a sheet accommodation section. The transport unit has a transport path along which a sheet read at a read position is transported to an output unit. The sheet output by the output unit is loaded onto the load section. The sheet accommodation section is disposed downstream in an output direction of the sheet from an inner wall surface extending upward adjacent to the load section and has a recess capable of accommodating a sheet of a predetermined minimum size. A retrieval space through which the sheet accommodated in the sheet accommodation section is retrievable is provided by exposing the transport path in a direction opposite to a loading direction of the sheet.

An image forming apparatus includes a stacking tray, a control unit, an alignment member and a supporting mechanism. The control unit performs a rotational sorting. An alignment member includes a leading end wall coming into contact with a leading edge of a portrait sheet stack, a pair of first side walls coming into contact with both side edges of the portrait sheet stack and a leading edge of a landscape sheet stack, and a pair of second side walls coming into contact with both side edges of the landscape sheet stack and aligning the portrait sheet stack and the landscape sheet stack. The supporting mechanism supports the alignment member so as to be movable in an alignment position where the alignment member protrudes from an upper face of the stacking tray and in a retracting position where the alignment member retracts from the upper face of the stacking tray.

An image forming apparatus includes an image forming section, a discharging roller pair, a plurality of trays, a guide member, and a controller. The image forming section forms an image on each of a plurality of sheets. The discharging roller pair discharges each of the sheets. The sheets discharged by the discharging roller pair are to be stacked on the trays (first through third trays). The guide member guides each of the sheets from the discharging roller pair toward a discharge destination tray among the plurality of trays. Every time the discharging roller pair discharges one of the sheets, the controller controls the guide member to change the discharge destination tray. The trays are configured such that leading ends of the sheets are superposed on one another.
