  • Patent number: 9352916
    Abstract: A sheet conveying device includes a first rotating member, a second rotating member, and a biasing unit that biases the second rotating member toward the first rotating member. The first and second rotating members pinch a sheet therebetween and convey the sheet in a sheet conveying direction. The second rotating member includes a small-diameter portion that faces a conveying portion of the first rotating member, and a large-diameter portion at a position axially displaced from the conveying portion. The second rotating member can change its orientation to an orientation where a rotating shaft of the second rotating member is tilted relative to a rotating shaft of the first rotating member as viewed in the sheet conveying direction, thereby moving a position of an end portion of the second rotating member on a side of the large-diameter portion away from the rotating shaft of the first rotating member.
