A post-processing apparatus includes a storing unit in which plural recording media are stored for performing post-processing and a transport member that transports a recording medium to the storing unit as a result of rotating while being in contact with a surface of the recording medium. The transport member includes a blade that comes into contact with a recording medium and a reinforcing portion that reinforces a strength of a portion of the blade that does not come into contact with the recording medium.

A post-processing apparatus includes an ejection tray receiving a recording medium that is ejected, an elastic member urging the ejection tray upward in a vertical direction, a moving mechanism causing the ejection tray to move up and down in the vertical direction, and a driving source driving the moving mechanism.

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 convey the print medium printed by the printing unit to the stacking portion, a passage forming portion arranged above the stacking portion so as to face 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 discharge passage in a conveying direction of the print medium. In the outlet port, the passage forming portion extends to the downstream side of the stacking portion in the conveying direction.

A sheet conveying device, which is included in a sheet discharging device and an image forming apparatus, includes a contact body configured to rotate while contacting a sheet in conveyance, a shaft configured to rotate together with the contact body in a range of rotation of the contact body, a sheet detector configured to detect the sheet through detection of rotation of the shaft, and a rotary body support configured to rotatably support the contact body to the shaft, extending the range of rotation, in a same direction as the direction of rotation of the shaft. The sheet discharging device includes a sheet discharging body, a sheet stacker of the sheet discharged, and the above-described sheet conveying device. The sheet detector is a stack height detector configured to detec't that the height of the sheet stacked on the sheet stacker is equal to or higher than a predetermined height.

In a sheet discharge mechanism for enabling a wide range of sheets stored on a sheet discharge tray from a processing section, a brake lever for reducing a velocity of a sheet fed from a sheet discharge outlet is held detachably relative to an attachment frame above the sheet discharge tray, and it is possible to select whether brake action is made corresponding to sheet discharge conditions. A sheet discharge mechanism includes a sheet discharge path having a sheet discharge outlet, a sheet discharge tray disposed on the downstream side of the sheet discharge outlet with a level difference, and a brake section of a sheet carried out at the sheet discharge outlet, wherein the brake section includes a lever member in which its base end portion is axially supported by an attachment frame, and its front end portion moves up and down corresponding to a load amount of sheets.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

A sheet processing device is for binding sheets together. The sheet processing device includes binding units differing from each other in maximum sheet count, the maximum sheet count being a maximum number of sheets that can be bound at a time; a sheet tray configured to hold sheets until all to-be-bound sheets are placed therein, the number of the to-be-bound sheets being a largest one of the maximum sheet counts of the binding units or smaller; and a stacked-sheet-count limiting unit situated in a thickness direction of the sheets held in the sheet tray. The stacked-sheet-count limiting unit is configured to limit the number of sheets held in the sheet tray by varying a distance from a sheet support surface of the sheet tray on which the sheets are placed, depending on one of the binding units by which the sheets held in the sheet tray are to be bound.

Apparatus is described that has a flexion component configured to apply a force to a first portion of media within a media path of a media processing device. The apparatus has a support portion configured to couple the apparatus to the media processing device. The media path provides a path along which the media is transported and has a feed area. The flexion moves a second portion of the media away from the feed area of the media path. A method of applying a force to media is also described.

A processing device includes a processing unit and a medium accommodation portion, and the medium accommodation portion includes a flexible sheet-like accommodation member, a pivot shaft to which one end of the accommodation member is coupled, an operation portion to which the other end of the accommodation member is coupled and that is provided separably from the pivot shaft, and a pair of support portions that supports both ends of the operation portion, and the accommodation member is wound around the pivot shaft and stored inside the housing when the operation portion approaches the pivot shaft, and is unwound from the pivot shaft and hung down to accommodate the medium when the operation portion is separated from the pivot shaft, and holds a weight closer to the other end than to an intermediate position between the one end and the other end in the advance and retreat direction.

A sheet discharge device includes a discharge portion, a sheet stacking tray, a pair of alignment members and a pair of width regulation members, a shift portion, and a control portion. The pair of alignment members include an arm portion formed of a rigid body, and an alignment portion formed of a flat-shaped elastic material and fixed to a swingable end of the arm portion. In the sorting processing, when stacking a sheet at a first position, the control portion causes a first alignment member to ride on a top surface of the sheet and a first side edge of a second alignment member to make contact with the sheet, and, when stacking the sheet at a second position, causes the second alignment member to ride on the top surface of the sheet and the first side edge of the first alignment member to make contact with the sheet.
