A paper ejection tray assembly for ejecting paper in an ejecting direction in an image reading device includes a tray body including a stacking surface for stacking an ejected paper, and a slide tray part which is pulled out from the tray body by a force, and a flap part which moves to an inclined position by the force when the slide tray part is pulled out. A height of the flap part from the stacking surface, at the inclined position gradually becomes higher from an upstream side toward a downstream side of the ejection direction to guide an ejected paper.

An image forming apparatus includes an ejecting port, an ejected sheet tray and a guiding member. The ejected sheet tray has a sheet stacking face inclined upwardly towards a downstream side from a lower side of the ejecting port. The guiding member is provided at a position on the sheet stacking face to contact with a tip end of the ejected sheet at the position. The guiding member includes a base member attached to the sheet stacking face, a movable guide for stacking the ejected sheet and a biasing member. The movable guide is turnably supported on the base member around a supporting shaft. The biasing member is interposed between the base member and the movable guide at an upstream side from the supporting shaft to bias the movable guide upwardly. The movable guide is turned downwardly against a biasing force of the biasing member by weight of stacked sheets.

A recording apparatus includes: a mount base having a mount surface on which a sheet discharged through a medium discharge outlet is mounted, the mount surface facing the recording surface of the sheet; a projection rib that is provided in the mount base, is projectable from the mount surface, and extends along a discharge direction of the sheet discharged through the medium discharge outlet, through a center of the sheet in a width direction crossing the discharge direction of the sheet; and a projection mechanism that causes the projection rib to project from the mount surface to a rib height according to a dimension of the sheet in the width direction discharged through the medium discharge outlet.

A paper feed device and a paper feed method that, even in a case where the number of paper sheets remaining on a paper sheet stacking plate is low, allow paper sheet changing to be facilitated. There are included a paper sheet push-up member for pushing up from below a paper sheet batch on the paper sheet stacking plate and a push-up member driving device that, in a case where the number of paper sheets in the paper sheet batch on the paper sheet stacking plate is not higher than the prescribed number, makes at least a part of the paper sheet push-up member protrude upward beyond the upper surface of the paper sheet stacking plate. Thus, a lower surface of the paper sheet batch placed on the paper sheet stacking plate is pushed up from below, thereby creating a clearance.

An imaging device having a sheet restraint sensing system is disclosed. The system includes a frame having an opening, a linear sensor strip located on the frame having a length, and a media tray having a sheet restraint that presses against the linear sensor strip when the media tray is located in the opening. The sheet restraint is constrained by the media tray to move relative to the media tray no more than a maximum adjustment displacement. The maximum adjustment displacement is less than the length of the linear sensor strip. Other systems are disclosed.

An image forming apparatus includes an image forming portion, a sheet discharging portion, and a sheet stacking portion. The stacking portion includes a first member including an inclined surface inclined upward toward a downstream side of a sheet discharging direction, and a second member including a stacking surface which projects upward from the inclined surface and on which the discharged sheet is stacked. The second member is rotatable relative to the first member about a supporting point provided upstream of the stacking surface with respect to the sheet discharging direction. The second member is rotatable about the supporting point in a direction in which the stacking surface moves downward in accordance with an increase in number of sheets stacked on the stacking surface.
