Abstract:
1. A curve correction mechanism for correcting a direction and degree of curvature of a reflecting mirror that reflects a light beam, the curve correction mechanism comprising: a support contacting a first end of the reflecting mirror in a longitudinal direction thereof to support the reflecting mirror; a pressing member to press against the reflecting mirror, the pressing member including: an adjuster to contact and move the pressing member between a first position, where the first pressing portion of the pressing member presses against the outboard portion of the reflecting mirror while the second pressing portion of the pressing member is isolated from the reflecting mirror, and a second position, where the second pressing portion of the pressing member presses against the inboard portion of the reflecting mirror while the first pressing portion of the pressing member is isolated from the reflecting mirror, wherein when pressure exerted by the first pressing portion against the outboard portion of the reflecting mirror increases, pressure by the second pressing portion against the inboard portion decreases, and when pressure exerted by the second pressing portion against the inboard portion of the reflecting mirror increases, pressure by the first pressing portion against the outboard portion decreases.
