摘要： A sheet conveyance device includes a conveyance roller having first and second end portions in a rotation axis direction, an open bearing supporting the first end portion, a frame supporting the open bearing, and a second end support portion supporting the second end portion. The open bearing includes a roller support portion supporting the conveyance roller and an open portion allowing the conveyance roller to be removed through the open portion from the roller support portion in a direction perpendicular to a rotation axis. The open bearing is movable from a first position, at which the conveyance roller is restricted from moving, to a second position at which the conveyance roller can move in the rotation axis direction. The second end portion is removable from the second end support portion by moving the conveyance roller from the second toward first end portion with the open bearing at the second position.
