  • 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: 10402664
    Abstract: A processing apparatus includes a distance image acquirer, a moving-object detector, a background recognizer. The distance image acquirer acquires a distance image containing distance information of each pixel. The moving-object detector detects a moving object from the distance image. The background recognizer generates a background model in which a stationary object recognized as background of the moving object is modeled, from the distance image acquired by the distance image acquirer. The moving-object detector changes a method for detecting the moving object, based on a relative positional relation between the moving object and the background model.

  • Patent number: 10298807
    Abstract: An image forming apparatus includes an image processor, a converter, a light source driver, an identifying unit, and a pattern generator. The image processor generates image data of first resolution and generates tag information indicating whether to perform image processing and associated with pixels of the image data of first resolution. The converter converts the image data of first resolution to image data of a higher second resolution. The light source driver drives a light source using a modulation signal corresponding to the image data of second resolution. The identifying unit identifies a target pixel to be subjected to image processing in the image data of first resolution based on the tag information. The pattern generator generates an image-processed pixel pattern of the second resolution according to the target pixel.

  • Patent number: 10262117
    Abstract: An information processing system includes an information processing apparatus, a server, first and second obtaining units, an addition unit, and a second processing unit. The first obtaining unit obtains second information indicating first information held by the server when the information processing apparatus has not previously included the first information to perform second processing necessary for first processing. When receiving a first request for requesting to perform the first processing, the second obtaining unit obtains token information indicating the presence of the authority to use the second information. When the second obtaining unit has obtained the token information, the addition unit adds the token information to a second request for requesting to perform the second processing. Only when the token information has been added to the second request, the second processing unit performs the second processing by using the second information.
