Abstract

Disclosed is a reflection-mirror support structure in a raster scanner having at least one reflection mirror on a light path between a light source and a photosensitive body so that in repsonse to an image signal a beam is moved to perform scanning for every scanning line through a beam deflection means to thereby write a latent image corresponding to the image signal on the photosensitive body. The reflection-mirror support structure comprises a stopper member for restricting a lower end edge position of the reflection mirror, a support member for supporting the reflection mirror slantingly at a predetermined angle, a holder member for positioning the reflection mirror relative to the stopper and the supports and for holding the reflection mirror, and a vibration suppressing member for urging a substantially-central portion of an upper end edge of the reflection mirror against the stopper, whereby the vibration of the reflection mirror is surely suppressed while keeping the surface flatness of the reflection mirror well so that the beam scanning position on the photosensitive body is made so as not to be displaced to thereby maintain the good printing quality.
