ABSTRACT:
An optic axis adjusting mirror device used with a system in which a light beam such as a laser beam or the like is used and modulated by information signals and caused to scan a medium by a scanning optical system. The device includes an adjuster capable of freely adjusting the angle at which the mirror is mounted to vary the direction of reflection of the light beam as it impinges on the mirror, and detecting jigs for detecting the position of the light beam as it impinges on the mirror and for detecting whether or not the optic axis lies at a predetermined position. The device contributes to highly accurate beam scanning.
