A sheet stacking device includes a sheet outlet, a lower discharge roller, and a paddle member. The paddle member is disposed coaxially to a rotation shaft of the lower discharge roller, and is driven to rotate independently of the lower discharge roller in the same direction as the lower discharge roller, so as to contact downward an upstream part in a discharging direction of a sheet discharged through the sheet outlet. The paddle member includes a base part in which the rotation shaft is inserted, an arm part protruding in a direction separating from an axis center of the base part, and a paddle elastic part protruding from the arm part. A rotation speed of the paddle member is the same as a rotation speed of a discharge roller pair when the sheet passes through a nip of the discharge roller pair.

Stack limiting unit for sheet processing device

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 for conveying molded body for heat exchanger fins

The problem of providing an apparatus for conveying a molded body for heat exchanger fins that is capable of realizing high speed conveying of the molded body for heat exchanger fins, preventing the generation of noise during conveying, and miniaturization is provided.

A sheet feeding device includes a sheet feeding body, a sheet separating body, a loading body, a support, and a pressing body. The sheet feeding body is configured to feed a recording sheet. The sheet separating body is configured to separate the recording medium and convey the recording medium together with the sheet feeding body. The loading body is configured to load the recording medium to be fed by the sheet feeding body. The support is disposed above the sheet separating body. The pressing body is made of metal and rotatably supported by the support between the loading body and the sheet separating body. The pressing body includes a part-shaped face to contact or face the recording medium. A surface of the part is covered with a metal plating.

Delivery device and method for operating a delivery device

A delivery device for a sheet-processing machine, comprises at least one deposition station and a conveyer station, by the use of which, upstream-processed sheets of printed material can be picked up in a transfer location, and can be conveyed through the deposition station via a first conveying system, where they can be deposited optionally to form a stack, or can be conveyed beyond that stack. A holding device, which holds down the uppermost sheet of the stack during the transfer of a sheet to be conveyed against an entrainment or a lifting, is provided with one or with a plurality of holding assemblies which are spaced apart from each other transversely to the transport direction. A sheet-guiding element may be provided, which adjoins the deposition station and which is variable in its vertical position with at least its upstream end by the use of an actuating drive.
