  • Rotary body for a polygonal mirror type scanner and method of machining the same
    Patent number: 6175439
    Abstract: A rotary body for use in a polygonal mirror type scanner includes an element for causing the rotary body to rotate. The element is mounted to a mounting portion by press fitting while a stress ascribable to press fitting is prevented from being transferred to the side of the rotary body. The mounting portion is formed integrally with one of opposite major surfaces of the rotary body perpendicular to the side. The rotary body includes a minimum number of parts, does not need highly accurate adhesion, has high durability, and is easy to produce and free from deformation apt to occur on its side.
