Abstract: A sheet feeding apparatus includes an upper support portion formed integrally with a side plate and configured to support an electric circuit board; an upper opening portion formed in the side plate near the upper support portion; a lower support portion provided at a separate part mounted to the side plate and configured to support the electric circuit board; and a lower opening portion provided between the side plate and the separate part. All line segments having a length of 50 mm or less, among line segments extending from arbitrary points in a main body portion of a sheet cassette, through arbitrary points in the upper opening portion, to the electric circuit board, form an angle of 45° or more with respect to a vertical line, and the lower opening portion has a dimension of 5 mm or less or a width of 1 mm or less.

Abstract: 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.

Abstract: 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.

Abstract: An image forming apparatus includes an apparatus body, a door, a first guide, a second guide configured to move from a first position to a second position, a first illumination device, and a second illumination device. The first illumination device is configured to illuminate a door side of the second guide positioned in the second position, with the door side of the second guide being closer to the door than a conveyance center line of the conveyance path in a width direction orthogonal to a sheet conveyance direction of a sheet which is conveyed in the conveyance path. The second illumination device is configured to illuminate in a direction different from a direction in which the first illumination device illuminates, and the second illumination device is configured to illuminate a space between the first guide and the second guide positioned in the second position.

Abstract: 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.
