Abstract
Apparatus and method for detachably mounting and balancing a polygon mirror body onto a rotating motor hub to reflect a scanning beam of light used in reading bar codes. A bowed retaining ring engages a grooved stub structure that protrudes through a center aperture of a closed end of a cylindrical mirror support body such that the retaining ring can be removed and the polygon mirror body repositioned by rotation relative to the motor for optimal center of mass balance relative to the motor rotation, and reset the mirror body by the retaining ring at such optional balanced position.
