  • Patent number: 10852683
    Abstract: A sheet conveyance apparatus includes a first oblique-feed unit configured to convey a sheet by imparting to the sheet a force in a first direction inclined relative to the sheet conveyance direction so that the sheet approaches an abutment surface in the width direction as the sheet proceeds downstream in the sheet conveyance direction; and a second oblique-feed unit configured to convey the sheet by imparting to the sheet a force in a second direction inclined relative to the sheet conveyance direction so that the sheet approaches the abutment surface as the sheet proceeds downstream. An angle of the first direction with respect to the sheet conveyance direction is greater than an angle of the second direction with respect to the sheet conveyance direction, and the second oblique-feed unit is disposed at a position closer to the abutment surface than the first oblique-feed unit in the width direction.

  • Patent number: 10120320
    Abstract: A sheet transport device includes a transport unit that transports a sheet, an endless belt that transmits a driving force from a motor to the transport unit, a rotary member that rotates by being pressed by the sheet transported by the transport unit, and a sensor that generates a signal in accordance with rotation of the rotary member. The rotary member is arranged in such a manner that a portion of the rotary member faces an inner peripheral portion of the endless belt.

  • Patent number: 9969579
    Abstract: A sheet conveyance apparatus includes first and second conveyance rollers, a holding member configured to rotatably hold the second conveyance roller, and an urging member to urge the holding member in a pressing direction. In addition, a reduction portion reduces a force applied to an openable member by the urging member when the openable member is opened or closed. The reduction portion includes a swingable member swingably supported by the openable member and movable to a first position, at which the swingable member causes the second conveyance roller to be pressed against the first conveyance roller, and a second position at which the swingable member causes the second conveyance roller to be separated from the first conveyance roller. The urging member is disposed between the swingable member and the holding member and urges the swingable member to swing toward an abut portion.
