ABSTRACT:
A light beam scanning apparatus used for image recording or read-out comprises a light deflector for deflecting a light beam, an image forming lens for forming an image of the light beam on a predetermined straight line, and a long sub-scanning mirror provided moveably in the optical axis direction of the image forming lens and extending in a main scanning direction in the form inclining with respect to the optical path of the light beam passing through the image forming lens. A scanning sheet holding device holds the scanning sheet on a plane formed by a locus of a straight line moving as the sub-scanning mirror is moved in the optical axis direction of the image forming lens and lying at a position conjugate with the predetermined straight line, on which the image of the light beam is formed by the image forming lens, with respect to the sub-scanning mirror.
