  • Patent number: 11927907
    Abstract: An image forming device including a gate mechanism reduces a noise generated when a sheet is conveyed. The image forming device includes a conveyance path and a gate. The conveyance path is branched into a plurality of paths, and the sheet is conveyed along a conveyance direction. The gate is provided at a position in the conveyance path at which the conveyance path is branched into the plurality of paths, and switches a path through which the sheet is conveyed. The image forming device rotates the gate in a direction in which a contact point of the gate, which faces a front surface of the sheet to be conveyed and is located at a position at which a trailing end of the sheet first comes into contact with the gate, and a front surface of the sheet to be conveyed face each other.

  • Patent number: 11760588
    Abstract: A sheet stacking part stacks sheets. A first roller applies a force in a conveyance direction to an uppermost sheet among sheets stacked on the sheet stacking part by rotating in a forward direction. A second roller is separated from the first roller on the downstream side in the conveyance direction. The second roller applies the force in the conveyance direction to the uppermost sheet by rotating in the forward direction. A controller controls rotation of the first roller and the second roller so that a second main operation is performed after a first main operation. The first main operation is an operation of rotating only the first roller of the first roller and the second roller in the forward direction. The second main operation is an operation of rotating both the first roller and the second roller in the forward direction.

  • Patent number: 8879833
    Abstract: A method and apparatus for generating an image of a seal impression. Irradiation of a face of a seal with N beams of light striking the face in succession from N respective different directions respectively corresponding to N different angles of incidence of the light on the face is caused, the face having a character thereon, N?2. N still images of the face corresponding respectively to the N beams are acquired, each still image structured as pixels including a RGB color combination. The N still images are combined to generate a composite image of pixels that includes a common area of pixels that commonly appears on the face of the seal in all still images, the common area having a luminance value exceeding a specified luminance threshold, the common area including a character area pertaining to where the engraved character is located on the face of the seal.
