  • Publication number: 20140239578
    Abstract: A sheet discharging device, which is included in an image forming apparatus, includes a sheet discharging tray, a sheet discharging roller pair, a full state detection feeler pivotably supported and including a center feeler to measure a height of a center part of the recording medium and an edge feeler to measure a height of an edge part of the recording medium, and a full state detection sensor to detect a position of the full state detection feeler. A distance between a leading edge of the center feeler and an upper surface of the sheet discharging tray is smaller than a distance between a leading edge of the edge feeler and the upper surface thereof. The leading edge of the edge feeler is located closer to the upper surface of the sheet discharging tray than a common tangential line of the sheet discharging roller pair.

  • Publication number: 20140091518
    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.
