  • Patent number: 11383943
    Abstract: A feeding apparatus includes a stacking portion, a regulating portion, a moving portion, and a detection unit. The regulating portion abuts, in a width direction, one side of stacking portion sheets having different widths and regulates movement of the sheets in the width direction. The detection unit detects a position of the moving portion in an intersecting direction. The regulating portion includes an abut portion. By abutting or not abutting the abut portion, the moving portion moves to a first position and a second position. When the moving portion moves to the first position or the second position in a predetermined proceeding direction, the moving portion does not move from the first position or the second position while the regulating portion takes a position where the regulating portion further moves in the predetermined proceeding direction.

  • Patent number: 11343399
    Abstract: An image reading apparatus includes a transport unit which transports a document, and reading units which read an image of the document which is transported. It is assumed that an operation of reading an image when specific setting information is not input to a control device of the image reading apparatus is set to a first reading mode, and an operation of reading an image when specific setting information is input to the control device is set to a second reading mode. In this case, in the second reading mode, image data of an image with a resolution which is equal to that in the first reading mode is generated, while causing the reading units to read an image from a document which is transported by the transport device at a lower speed than that in the first reading mode.

  • Patent number: 10569979
    Abstract: There is provided with a sheet feeding apparatus. A biasing unit generates a biasing force of biasing a storage unit in an insertion direction. A repulsive unit generates a repulsive force of biasing the storage unit in a direction opposite to the insertion direction. A fixing unit fixes the storage unit in a fixing position. The biasing unit starts generating the biasing force in a repulsion start position where the repulsive unit starts generating the repulsive force, or on an upstream side of the repulsion start position, in the insertion direction, and stops generating the biasing force before the storage unit reaches the fixing position. A biasing Zone in which the biasing unit generates the biasing force and a repulsive zone in which the repulsive unit generates the repulsive force partially overlap each other.
