Abstract
An apparatus that transfers an optical element includes: a driving unit that generates a driving force in response to an external signal, a rotating plate that rotates due to the driving unit, a first deceleration unit that is rotatably in frictional contact with the rotating plate, a rotating shaft that has an outer screw surface and that rotates by being mated to the first deceleration unit, an intermediate plate that is rotatably in frictional contact with the first deceleration unit, a second deceleration unit that is rotatably in frictional contact with the intermediate plate, a transmission unit that transmits an external rotational force to the second deceleration unit, and a moving unit that supports the optical element and that is engaged with the outer screw surface of the rotating shaft and moves with the rotating shaft as the rotating shaft rotates.
