A sheet storage device for storing sheets includes a supporting unit, a regulation unit, and a moving unit. The supporting unit supports stored sheets. The regulation unit is movably arranged on the supporting unit, and regulates a position of an edge portion of a sheet. The moving unit moves the regulation unit. The moving unit includes moving members to move in a direction parallel to a moving direction of the regulation unit. The moving members are moved by rotation of a rotation member in a case where the rotation member is in contact with the moving members. In a case where a fixing member attached to the sheet storage device in place of the rotation member, movement of the moving members is regulated by placing the moving members into contact with the fixing member.

An adjustable leveling assembly for engaging a stack of a plurality of sheets in a feeder tray of a printing device, including a first wedging element slidably arranged on the feeder tray and operatively arranged to engage the stack, wherein when the first wedging element is disengaged with the stack, a top sheet of the plurality of sheets is non-parallel to the feeder tray, and when the first wedging element is engaged with the stack, the top sheet is substantially parallel to the feeder tray.

An according to an aspect, a paper feed device includes a device body and a paper feed cassette inserted into the device body along an insertion direction. The paper feed device includes a lock lever mounted to the paper feed cassette via a lever shaft; a spring that applies a rotational force which rotates the lock lever in an engagement direction; and a lock member provided at the device body.

According to one embodiment, a sheet cassette includes a sheet placing portion. The sheet placing portion can rotate around a rotation shaft while placing a sheet of a placeable maximum size in a sheet placing area to be flat. The rotation shaft extends to be perpendicular to a discharge direction and a gravity direction of the sheet. The rotation shaft is disposed between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

The present invention provides a denesting apparatus (100, 200), the apparatus comprising: ⋅—one or more closed loop conveying tracks (130, 230), each closed loop conveying track comprising a plurality of sets of one or more de-stacking means (140, 240) movingly configured thereon through one or more de-stacking means moving mechanism (150, 250); ⋅—one or more stacking magazines (120, 220), each adapted to hold a stack of sheets (110, 210) supported thereon; wherein each of the plurality of sets of de-stacking means is adapted to selectively engage an uppermost sheet from at least one of the stacking magazines in any desired order either sequentially and/or simultaneously so as to discharge the picked-up sheets onto an out-feed conveyor (180, 280) in any desired manner either one besides another or otherwise one overlapping the other.

An image forming apparatus includes a sheet feeding device having a plurality of sheet feeding units, an opening and closing controlling unit, and a receiving unit. The opening and closing controlling unit controls opening and closing of the sheet feeding unit. Where the receiving unit receives an instruction for assigning a sheet having selected one attribute to designated one sheet feeding unit, the opening and closing controlling unit opens the designated one sheet feeding unit.

A sheet feeding apparatus includes an apparatus body, a drawer portion including a first contact portion, a feeding portion, and a pivot member configured to pivot between a first position and a second position, the pivot member constituting a part of a conveyance path at the first position, wherein the pivot member does not overlap a moving path of the drawer portion in a case where the pivot member is located at the first position, and overlaps the moving path in a case where the pivot member is located at the second position. The pivot member includes a second contact portion that pivots the pivot member from the second position toward the first position while being in sliding contact with the first contact portion in a case where the pivot member is located at the second position and the drawer portion is being inserted into the apparatus body.

The image forming apparatus may include a main body and a cassette to enter or exit the main body along a first direction to be mounted in or released from the main body, respectively. The cassette may include a supporter extendable in a second direction perpendicular to the first direction to protrude from an exterior of the main body. The main body may include a lever which is movable in the first direction between a supporting position at which the lever supports the main body and a release position at which to allow the cassette to enter or exit the main body along the first direction.

A feed device includes: a feed tray configured to accommodate a roll, in which a medium is rolled in a roll shape, rotatably; a housing configured to support the feed tray installable; and a pull-back mechanism configured to pull back the medium unrolled from the roll in a direction orthogonal to a rotation axis of the roll in conjunction with an outward movement of the feed tray from the housing in the direction orthogonal to the rotation axis of the roll.

A feeding apparatus includes a stacking portion, a regulating portion, a moving portion, and a detection unit. The regulating portion abuts, in a width direction, one side of stacking portion sheets having different widths and regulates movement of the sheets in the width direction. The detection unit detects a position of the moving portion in an intersecting direction. The regulating portion includes an abut portion. By abutting or not abutting the abut portion, the moving portion moves to a first position and a second position. When the moving portion moves to the first position or the second position in a predetermined proceeding direction, the moving portion does not move from the first position or the second position while the regulating portion takes a position where the regulating portion further moves in the predetermined proceeding direction.
