Abstract
A polygonal mirror fixing device comprising a rotary body, to which a polygonal mirror is adapted to be mounted, has a mounting circumferential surface in a center opening of the polygonal mirror and a mounting bottom surface which projects from the mounting circumferential surface in the radially outward direction. A mirror pressing member which is composed of the same material as the polygonal mirror is positioned to have contact with an axial end surface of the polygonal mirror, the other side from the end surface the contacts the mounting bottom surface. A mirror fixing member and a spring member are attached axially to the other side of the mirror pressing member to press the mirror pressing member in the axial direction. By the pressing force of the mirror fixing member in the axial direction, the mirror pressing member is pressed in the axial direction toward the mounting bottom surface so that the polygonal mirror is fixed.
