Conveyance device

A cover stopper engages a cover engaging portion when a cover is located at a closed position and to restrict rotational movement of the cover toward an open position. A rotation guide contacts, from above, a rib engagement surface during rotational movement of the cover and to guide rotational movement of the cover between the open position and a relay position. An urging member urges the cover from the relay position toward the closed position. When the cover rotationally moves from the open position to the relay position, a rib and the rotation guide engage each other to restrict upward movement of the cover against urging force of the urging member. When the cover reaches the relay position from the open position, the rib and the rotation guide become disengaged and the cover moves to the closed position where the cover engaging portion and the cover stopper engage each other.
