Abstract: The invention makes it possible to carry out an emergency eject motion without attaching and detaching teeth between gears in a transmission system of a driving force of a loading motor, in an optical disc apparatus.

Abstract: A controller 27 controls the driving member 2 to move the conveyer 23 as a second member to a target position of the receiving rack 10 as a first member in the other direction after moving the conveyer 23 over the target position when the conveyer 23 is moved in one direction to align the conveyer 23 with the target position. After the conveyer 23 is moved over the target position and when the conveyer 23 is moved in the other direction, the controller controls the conveyer 23 to move by a distance of a mechanical error at a time, and then to move intermittently to the target position for aligning the conveyer 23 with the target position.
