The controller may control the focusing mechanism for each rotational position of the rotating-type scanning system. In a particular case, the controller may control the focusing mechanism according to the rotational position of the rotating-type scanning system and according to an initial position of the focusing mechanism determined at a predetermined position of the rotating-type scanning system.
