A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position.

A discharging device includes an aligning unit for aligning stacked sheets as a sheet bundle, a discharging unit for discharging the sheet bundle, a discharged tray on which the sheet discharged by the discharging unit is stacked, and a support unit. The support unit supports the sheet bundle from below by extending in a sheet discharging direction of the sheet bundle while the sheet bundle is discharged to the discharged tray and to be accommodated in a direction opposite to the sheet discharging direction at timing when the discharging unit finishes discharging the sheet bundle.

A sheet skew feed correcting apparatus is provided which includes: a driving rotation member that is driven to rotate; a first driven rotation member that is pressure contacted against the driving rotation member; a first holder rotatably holding the first driven rotation member; a second driven rotation member that is pressure contacted against the driving rotation member; a second holder rotatably holding the second driven rotation member; and a shutter portion with which a leading end of a sheet comes into contact for skew feed correction, the shutter portion moving pivotally with one end portion thereof supported by the first holder and another end portion thereof supported by the second holder; wherein the shutter portion has abutting portions with which the leading end comes into contact, and a coupling portion extending so as to couple the abutting portions together between the first and the second driven rotation members.

A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to discharge the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged facing the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located at a downstream end of the stacking portion and a downstream end of the passage forming portion in a conveying direction of the print medium. The passage forming portion includes an opening/closing portion which is displaceable between a closed position for forming the discharge passage and an open position for opening access to the stacking portion.

In one example, a sheet media alignment system includes: a guide (12) defining a curved media path (14) that extends from an upstream part of the guide to a downstream part of the guide; a movable blocker (16, 56) to block the curved media path (14) at the downstream part of the guide, the blocker movable into and out of a blocking position in which the blocker is spaced from the downstream part of the guide a first distance; and a driver (24, 58) upstream from the curved media path to drive a media sheet into the guide along the curved media path and into the blocker. The driver is spaced from the upstream part of the guide a second distance greater than the first distance such that a media sheet driven into the blocker will buckle between the driver and the guide before it will buckle between the guide and the blocker.

A pick-up device disposed between an input tray and a feeding path includes a paper feeding unit for feeding paper, a separation roller disposed opposite to the paper feeding unit, a blocking arm disposed between the input tray and the paper feeding unit and configured to be switchably disposed between a blocking position for blocking the paper and a feeding position for passing the paper through the feeding path, and a guiding arm disposed in the feeding path through a pivot shaft and having a guiding portion. The pivot shaft is located upstream of the separation roller, and the guiding portion is swingably disposed in a seam space formed by the paper feeding unit and the separation roller.

A printing apparatus includes a stacking portion on which a print medium printed by a printing unit configured to perform printing is stacked, a discharge unit configured to discharge the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged facing the stacking portion and configured to form a discharge passage of the print medium together with the stacking portion, and an outlet port located in a downstream end of the stacking portion and a downstream end of the passage forming portion in a conveying direction of the print medium. The passage forming portion includes an opening/closing portion which is displaceable between a closed position for forming the discharge passage and an open position for opening the stacking portion.

A medium regulating component for use in a medium feeding device feeding sheet media accommodated in an accommodating unit, the component for regulating excessive floating of a medium accommodated in the accommodating unit, the component includes: a regulating member protruding in a horizontal direction from an accommodating unit periphery and contacting the floating medium; a holding member holding the regulating member in a non-contact state with the medium; a first rotating shaft rotatably supporting the regulating member relative to the holding member; and a second rotating shaft rotatably supporting the holding member relative to the accommodating unit, in which when the regulating member receives a pressing force from below in a gravitational direction, rotates about the first rotating shaft in a state where movement of the holding member is suppressed, and pushes the holding member to rotate about the second rotating shaft.
