A sheet discharge device includes a discharge member, a discharge tray and a stopper. The discharge tray includes a groove and a fixed magnetic body. The groove is formed along a discharge direction. The fixed magnetic body is disposed at a predetermined position along the groove. The stopper includes a guide piece, a contact piece and a moving magnet body. The guide piece is engaged with the groove in a slidable manner. With the contact piece, the leading edge of the sheet is allowed to be come into contact. The moving magnetic body generates a magnetic force in a direction in which the moving magnetic body and the fixed magnetic body are attracted each other. When the guide piece is slid along the groove and the moving magnetic body reaches the predetermined position, a resistance is applied to a sliding movement of the guide piece by the magnetic force.

A sheet feeding device includes a sheet stacking unit, a long sheet stacking unit, a first guide, a first detector, and a closing unit. The sheet stacking unit is movable up and down. Sheets are stacked on the sheet stacking unit. The long sheet stacking unit is detachably mounted on the sheet stacking unit. Long sheets are stacked on the long sheet stacking unit. The first guide is movable along a feeding direction through a groove. The first guide is deformable into a shape that does not interfere with the long sheet stacking unit. The first guide guides a rear end portion of the sheets in the feeding direction. The first detector is provided in the first guide. The first detector detects the sheets stacked on the sheet stacking unit. The closing unit is detachably attached to the groove in the sheet stacking unit. The closing unit closes the groove.

An image forming apparatus includes a cover portion and an auxiliary tray. The cover portion is displaced between a closing position for closing the supply port and an opening position for opening the supply port. The auxiliary tray is attached to a sheet stack surface of the cover portion, and supports the sheet, together with the cover portion at the opening position. The auxiliary tray is, either in a first attachment state or in a second attachment state, attached to the cover portion. In the first attachment state, a longitudinal direction of the auxiliary tray extends along a width direction that crosses a sheet insertion direction and the auxiliary tray is stored in the sheet stack surface. In the second attachment state, the longitudinal direction extends along the sheet insertion direction, and the auxiliary tray extends out from the cover portion toward an upstream in the sheet insertion 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.

A sheet aligning device includes a support member, a regulation member, a regulation member moving mechanism, and an alignment member. The support member supports leading ends of sheets. The regulation member is connected to the support member and is provided to face an inclined tray in such a way as to define a sheet entry space in which the leading ends of the sheets enter. The regulation member moving mechanism is configured to, each time a sheet is conveyed onto the inclined tray, move the regulation member in a separating direction to widen the sheet entry space, and then in an approaching direction to narrow the sheet entry space. The alignment member aligns the sheets by abutting on rear ends of the sheets.

A recording apparatus includes: an apparatus main body that includes a recording unit; a medium-receiving tray that is configured to be switched between a first state and a second state; and a motor, in which the medium-receiving tray includes a first tray, a second tray that is configured to be displaced with respect to the first tray and that is positioned further than the first tray from the apparatus main body when the medium-receiving tray is in the second state, a pinion gear engaged with a first rack formed in the first tray in a displacement direction of the second tray and with a second rack formed in the second tray in the displacement direction, and a displacement section that supports the pinion gear and that is displaced in the displacement direction in response to receiving power from the motor.

In one example, a media size detector includes a button coupled to a spring of a housing to interact with a media size adjuster of a media tray, a first side of a lever to receive pressure from the spring when the button is depressed by the media size adjuster, and a second side of the lever to apply pressure to activate or deactivate a switch coupled to a printed circuit assembly when the first side of the lever receives pressure from the spring.

A medium supply apparatus includes a box member and a lid. A medium is stored inside the box member. The box member is inserted into and extracted from a body of an image forming apparatus, and has a length in an extraction/insertion direction that is longer than a length of the body in the extraction/insertion direction. The lid is provided on a back side of the body in the extraction/insertion direction of the box member to cover at least an upper part of a portion of the box member that projects from the body. The lid includes a first member, a second member, and a first lug. The first member is movable in the extraction/insertion direction with respect to the body. The second member is connected to the first member so as to be relatively movable in the extraction/insertion direction with respect to the first member. The second member is moved by being pushed by the box member which is inserted into the body. The first lug is provided on the second member. The first lug is engaged with the box member by a force that presses the box member against the second member, and disengaged from the box member by a force that extracts the box member from the second member.

A medium containing device includes a supporting member composed with a first part, a second part and a third part connecting the first part and the second part wherein the supporting member is configured to cause the first part to incline by being lifted up from a standard position, and supports recording media. When the supporting member is in the standard position, a first height position of an upper face of a first base part in a region adjacent to the first part is lower than a second height position of an upper face of the first part in a region adjacent to the first base part, and a third height position of an upper face of the second part in a region adjacent to the first base part is lower than a fourth height position of an upper face of the first base part in a region adjacent to the second part.

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.
