<p>An optical element driver (1) includes a first optical element (2) movable in a light path direction extending along the light path at one position on the light path of a light beam, a second optical element (3) movable in an intersecting direction intersecting with the light path at another position and capable of changing over first and second states in which different optical characteristics are exhibited for the light beam when moved in the intersecting direction, and a shared driving means (4) for moving the first optical element in the light path direction and moving the second optical element in the intersecting direction.</p> |
