A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.

A medium transport apparatus includes a transport section configured to support a medium and transport the medium in a transport direction, and a wrinkle reducing section configured to come into contact with the medium to reduce the formation of wrinkles in the medium. The wrinkle reducing section can change surfaces to come into contact with the medium. The medium transport apparatus having such a structure enables to reduce the formation of wrinkles in the medium.

A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.

A sheet discharging device includes a shift tray 202 on which a sheet P1 is stacked, a discharging roller 6 that discharges a sheet P2 onto the shift tray 202, a blowing device 230 that sends air to a lower surface of the sheet P2 discharged by the discharging roller 6, a blocking member 231 that blocks air sent to the lower surface of the sheet P2 from a blowing port 230-2 of the blowing device 230, and a control unit that controls the blocking amount of the blocking member 231. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

A sheet ejection device comprises an ejection roller pair (20) which ejects a sheet by a pressure contact portion (N) in which a first roller (21) and a second roller (22) are in pressure contact with each other. In the first roller (21), protrusions (41) that protrude in a roller diameter direction in order to push the back end of the sheet ejected with the rotation of the first roller (21) are formed. The protrusions (41) are provided in a flange (45) at a predetermined distance from the peripheral end (43a) of a cylindrical portion (42) of the first roller (21) in a sheet width direction. The distance from the center of rotation of the flange (45) to the front end (41c) of each of the protrusions (41) is equal to or less than the radius of the cylindrical portion (42).
摘要:
A device for transporting flat objects, such as mail items, has two transport tracks and an acceleration device arranged between the transport tracks. The acceleration device includes a clamping pair for holding the objects in a clamped manner on their opposing flat sides while the objects are moving. To be able to carefully accelerate objects of different thicknesses, it is proposed that at least one clamp of the clamping pair includes a segment unit with several segments of different configuration for clamping objects of different thicknesses.

A discharge mechanism includes: a rotating shaft that is rotatable; a plurality of roll portions provided around the rotating shaft; an opposing member provided above the roll portions so as to oppose the roll portions, the opposing member holding and conveying a material to be conveyed, in cooperation with the roll portions so that the material to be conveyed is discharged onto a discharge section; and a protrusion formed on an outer periphery of the rotating shaft, the protrusion not protruding beyond the outer diameter of the roll portions.

Provided is a sheet delivery apparatus for delivering a sheet to a delivery tray, including: a pair of delivery rotary members for nipping and delivering the sheet guided by the guide portion; and a projection that rotates about an axis being the same as an axis of one of the pair of delivery rotary members, is abutted against a trailing end of the sheet, and pushes out the trailing end of the sheet toward a delivery tray side. The guide portion deforms the sheet so that the sheet does not contact the projection, and after the trailing end of the sheet has passed through the guide portion, the projection and the trailing end of the sheet are abutted against each other.
摘要:
To ensure that the leading edge of the sheet ejected onto a tray 12 does not push and move loaded sheets in advance, loaded sheets are retained at position (II) by a retaining roller. A roller (returning roller in this case) 121 for applying external force to a sheet S ejected onto the tray 12 and moving the sheet toward a end face 131 for alignment is displaced to a different position in the direction of ejection “a”, thereby firmly gripping the trailing edge of the sheet S ejected on the tray 12.
