Abstract: A sheet container includes a body and a feed tray. The body includes a guide rail having a protrusion at a contact position. The feed tray loads multiple sheets. The feed tray is insertable to and removable from the body along the guide rail in a horizontal direction and includes a contact in an upstream portion of the feed tray in a drawing direction along the horizontal direction. In response to the feed tray drawn from the body to the contact position, the contact contacts the protrusion to restrict drawing of the feed tray from the body.

Abstract: A sheet feeding device includes a storage, a discharger, an angle adjuster, and an urging body. The storage stores a sheet bundle. The discharger contacts and discharge an uppermost sheet of the sheet bundle from the storage in a sheet conveying direction in which the uppermost sheet is conveyed. The angle adjuster changes an angle according to a remaining amount of the sheet bundle in the storage. The urging body urges a trailing end of the uppermost sheet in the sheet conveying direction toward the discharger in stages according to the remaining amount.

Abstract: A sheet storage device includes a sheet positioning member that is movable in a first direction, and positions a sheet by abutting on a side end portion of the sheet at a side in the first direction. The sheet positioning member includes a moving body, an abutting portion, a first and a second biasing member, and a bias removing portion. The moving body is configured to move in the first direction. The abutting portion is supported by the moving body to be movable in the first direction and configured to abut on the side end portion when the sheet positioning member positions the sheet. The first biasing member biases the abutting portion toward the side end portion. The second biasing member biases the abutting portion against a biasing force of the first biasing member. The bias removing portion removes a bias applied by the second biasing member.

Abstract: A sheet stacking portion for stacking sheets is provided on a cover openably/closably supported on an apparatus body. The sheet stacking portion is guided between a first position and a second position along the cover by a guide portion. A sheet staked on the sheet stacking portion at the first position is fed via a sheet feeding portion. The sheet stacking portion is moved in conjunction with a cover closing action from the first position to the second position not interfering with the sheet feeding portion via a moving portion. A first end side of the moving portion is turnably supported on the apparatus body and a second end side is connected to the sheet stacking portion.
