摘要：
A light scanning device has a light deflector for deflecting in a scanning mode a light beam outputted by a light source; and an optical system for image-forming on a scanning medium the light beam deflected by the light deflecting means, with a convergent or divergent light beam in an optical path between the light source and the scanning medium. A plane-parallel plate is moved into and out of the optical path of the convergent or divergent light beam, so as to change a beam spot diameter on the scanning medium.
