    摘要: A sheet conveyance apparatus includes a sheet conveyance roller pair to convey a sheet, a first opening and closing guide that opens to a first opened position in which a first conveyance path through which a sheet is conveyed is opened and closes to a first closed position in which a sheet is conveyed in the first conveyance path, and a second opening and closing guide that opens to a second opened position in which a second conveyance path is opened and closes to a second closed position in which a sheet is conveyed in the second conveyance path. A first member is provided on the first opening and closing guide, and a second member is provided on the second opening and closing guide and pivots between a first position and a second position with respect to the second opening and closing guide.

    摘要: A one-way clutch includes: an outer member that has an inner periphery including an internal gear; an inner member that is rotatably disposed, and includes an engagement portion; and a planetary gear that is rotatable relative to the inner member, meshes with the internal gear, and is prevented from rotating by engaging with the engagement portion, wherein in a state in which the outer member and the inner member rotate together, the planetary gear engages with the engagement portion; in a state in which relative rotation between the outer member and the inner member is performed, the planetary gear disengages from the engagement portion; and in a state in which the planetary gear engages with the engagement portion, a top land of the internal gear abuts on a bottom land of the planetary gear.

    摘要: While the first opening and closing member is moved from the first closed position to the first opened position, a force transmitted to the second opening closing member by the first member interfering with the second member pivots the second opening and closing member from the second closed position toward the second opened position. While the first opening and closing member is moved from the first opened position to the first closed position, the second member retracts from the movement locus of the first member by interference of the first member with the second member, and the first opening and closing member is configured to move to the first closed position in a state where the second opening and closing member is positioned at the second closed position.

    摘要: An image reading apparatus includes a first roller including a first rotation shaft and a first roller portion, an image reading unit, a first guide portion, a second guide portion arranged downstream of the first roller in a sheet conveyance direction, the second guide portion being curved with respect to a direction orthogonal to an axial direction of a first rotation shaft and the sheet conveyance direction, and a second roller. A reading position is located in a region between a first straight line and a second straight line, the first straight line passing through a first end, in the axial direction, of the first roller portion and extending in the sheet conveyance direction, the second straight line passing through a second end, in the axial direction, of the first roller portion and extending in the sheet conveyance direction.

    摘要: A sheet feeder includes a sheet feeding unit configured to feed a sheet from a sheet storage case in a sheet feeding direction orthogonal to a loading direction in which the sheet storage case is loaded into an apparatus main body, and a conveying guide configured to guide the sheet fed by the sheet feeding unit. The conveying guide includes a first guide segment included in the apparatus main body and a second guide segment included in the sheet storage unit. The sheet feeder further includes an edge guide member disposed at an end of the first guide segment. The edge guide member has a guide surface that allows reaction force including a directional force component acting upward and a directional force component acting in a direction opposite to the sheet feeding direction to be generated when the sheet partly projecting from the sheet storage case abuts the guide surface.
