Abstract:
A curve correction mechanism for correcting a direction and degree of curvature of a reflecting mirror that reflects a light beam includes an adjuster to contact and move a pressing member between a first position, where a first pressing portion of the pressing member presses against an outboard portion of the reflecting mirror provided outboard from a support that supports the reflecting mirror in a longitudinal direction of the reflecting mirror while a 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 an inboard portion of the reflecting mirror provided inboard from the support while the first pressing portion of the pressing member is isolated from the reflecting mirror.
