ビーム走査装置。[Claims for Utility Model Registration] A reflecting mirror swinging mechanism that swings the reflecting mirror around a first axis that substantially coincides with the reflecting surface of the reflecting mirror, and a second axis that is perpendicular to the first axis. A barcode comprising: a reflecting mirror rotation mechanism that rotates the reflecting mirror as a center; and a light beam irradiation means that irradiates a light beam near the intersection of the first and second axes of the reflecting mirror. Light beam scanning device for readers.
