Abstract:
A light source, a polygon mirror mechanism, a deflection lens, and a mirror unit are housed in a casing. The mirror unit includes a base member of metal fixed to the casing and a mirror supporting plate attached to the base member. The mirror supporting plate is formed by a metal flat plate and includes a mirror supporting section. A holder member is attached to the mirror supporting section. An end of the mirror is held in the holder member by a spring member. The holder member is rotatable around an axis of the mirror. When the holder member is rotated, an angle of the mirror changes. After the angle of the mirror is adjusted, the holder member is fixed to the mirror supporting section by a fixing member.
