  • Patent number: 10974923
    Abstract: A sheet processing device includes a conveying unit, a presser, an end detector, and a setting unit. The conveying unit conveys a sheet having a crease formed therein. The presser presses the crease in the sheet. The end detector detects an end in a conveying direction of the sheet at a position upstream of the presser in the conveying direction. The setting unit sets a crease position where the crease is to be formed. Upon detection of the end in the conveying direction, the conveying unit conveys the sheet to a position where the crease faces the presser, on the basis of the crease position set by the setting unit. The presser presses the crease in the conveyed sheet.

  • Patent number: 10814423
    Abstract: An optical processing apparatus includes a light source, a condensing optical system, and a shaping optical system. The light source emits light. The condensing optical system condenses the light emitted from the light source onto a processing target position on a surface of an object to be processed. The shaping optical system shapes a spot shape of the condensed light, such that a ratio of a major axis diameter of the spot shape to a minor axis diameter of the spot shape, in a cross section orthogonal to an optical axis of the condensed light on the object to be processed, is a minimum at or adjacent to a focal position of the shaping optical system. A method for optically processing an object is also provided.

  • Patent number: 10807827
    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.
