  • Patent number: 10562733
    Abstract: 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.

  • Patent number: 10421307
    Abstract: A sheet binding unit includes a first sheet binder having first and second dentate uneven sheet binding elements to conduct a first sheet binding process by engaging each other by a prescribed meshing depth while sandwiching the sheet bundle therebetween to form a dentate unevenness on the sheet bundle at a first sheet binding portion of the sheet bundle, and a second sheet binder having third and fourth dentate uneven sheet binding elements to conduct a second sheet binding process by engaging each other by a greater meshing depth than that made by first and second dentate uneven sheet binding elements of the first sheet binder while sandwiching the sheet bundle therebetween to form a dentate unevenness on the sheet bundle at a second sheet binding portion different from the first sheet binding portion of the sheet bundle.

  • Patent number: 10289050
    Abstract: A binding device includes a receptacle, an aligner, a moving mechanism, first and second binders, and a guide. The aligner aligns a bundle of recording media in a width direction thereof on the receptacle. The moving mechanism moves the aligner in the width direction. A maximum thickness of the bundle of recording media boundable in the second binder is smaller than that in the first binder. The guide is movable conforming to the maximum thickness of the bundle of recording media boundable in the first binder, and conforming to that in the second binder, to guide and direct the bundle of recording media to a receiving portion of the first binder when the first binder binds the bundle of recording media, and to a receiving portion of the second binder when the second binder binds the bundle of recording media, respectively. The guide is movable in conjunction with the aligner.

  • Patent number: 9944488
    Abstract: A sheet processing apparatus includes a first binding unit configured to bind a sheet bundle; a second binding unit with greater number of bindable sheets than number of bindable sheets of the first binding unit; and a number-of-sheets determining unit configured to determine whether number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit. The first binding unit moves to a binding position, and if the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the first binding unit moves away from the binding position. When the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the second binding unit moves to the binding position.
