Abstract: A sheet storage device has a rotation restriction portion configured to restrict a rotation of an end cursor from a first posture to a second posture. The rotation restriction portion has: a restriction piece situated on the end cursor and configured to be brought into contact with a guide rail so as to restrict the rotation of the end cursor from the first posture to the second posture; and an engagement recess formed at a given position of the guide rail, the restriction piece being fitted in the engagement recess. The end cursor is allowed to rotate from the first posture to the second posture when the restriction piece is fitted in the engagement recess at the given position of the guide rail.

Abstract: An object of the present invention is to correct the deviation of a sheet in the width direction occurring on a conveyance path from a sheet correction mechanism (4) to a discharge tray. A sheet shift portion (41, 43, 44) moves a sheet in the width direction. A conveying position detecting portion (45, 46, 47) detects the position of the sheet in the width direction. A discharge position detecting portion (54, 8a) detects a discharge position of the sheet, in the width direction, discharged onto a discharge tray (33) in a sheet discharge portion (31). A control portion (8b) derives an amount of deviation between the discharge position and a discharge reference position based on a detection result of the discharge position detecting portion (54, 8a). Furthermore, the control portion (8b) corrects a conveying position of the sheet in a sheet conveying portion according to the amount of deviation.

Abstract: A sheet conveying device includes a sheet conveying passage, an upper conveying guide provided in the sheet conveying passage and facing the upper surface of a sheet, a lower conveying guide facing the lower surface of the sheet, a conveying member conveying the sheet along the sheet conveying passage, a sheet stack tray arranged above the upper conveying guide. The upper conveying guide is swingable up and down, with one end part of it in the sheet conveying direction or in the sheet width direction perpendicular to the sheet conveying direction serving as a pivot shaft. The sheet stack tray has a movable part making contact with the upper conveying guide at least when it swings, and the movable part is movable between a sheet receiving position where it forms a sheet stack surface and a retracted position where it has swung upward from the sheet receiving position.

Abstract: A sheet ejection device includes an ejection roller pair, a stacking tray, a protrusion member and a movement mechanism. The protrusion member is supported to be able to reciprocate between a protrusion position and a retraction position in a predetermined movement direction. The movement mechanism includes: a rotation shaft; a holding member; and a rack and pinion mechanism which includes a pinion gear and a rack gear. In at least a part of the rack gear in the movement direction, a narrow width region is provided which includes a narrow width gear and a cutout portion. In the narrow width region, the pinion gear is slidable between a meshing position and a release position, and in a state where the pinion gear has slid to the release position, the protrusion member can be relatively moved with respect to the pinion gear in the movement direction.

Abstract: A sheet conveyance device includes a sheet receiving part, a first discharge part, a sheet conveyance path, an escape conveyance path, a branch guide, an escape tray, a second discharge part, and a first sheet detection part. When a device failure occurs, the branch guide switches the conveyance direction such that the sheet remaining on the sheet conveyance path is discharged on the escape tray by the second discharge part, through the escape conveyance path sequentially. Then, the second discharge part stops a discharging of the sheet in a state where the sheet remains in the second discharge part when the sheet is a last sheet to be conveyed to the escape tray. Then, a receiving of a new sheet to the sheet receiving part from the image forming apparatus is inhibited while the first sheet detection part detects the last sheet.

Abstract: A sheet feeding device includes a housing, a sheet storage cassette, a slide rail and an upper contact member. The housing has a pair of inner walls facing each other. The sheet storage cassette is attached between the inner walls in an insertable and drawable manner along a first direction. The sheet storage cassette has a pair of wall parts facing the pair of inner walls. The slide rail includes an outer rail and an inner rail. The outer rail extends along the first direction on the inner wall and the inner rail extends along the first direction on the wall part. The inner rail is supported by the outer rail in a movable manner. The upper contact member is provided on the wall part and moves on an upper face of the outer rail when the sheet storage cassette is inserted and drawn with respect to the housing.
