Abstract
A device for holding, adjusting and driving a rotatable body such as a polygonal mirror or a polygonal mirror firmly attached to a bushing is disclosed. The rotatable body has a central bore which encloses an axis of rotation and is provided with a means for connecting the rotatable body to the axis of rotation. The means for connecting the rotatable body to the axis of rotation comprises a first fastening zone wherein the rotatable body is rigidly connected to the axis of rotation by an interference fit and a second fastening zone located at a distance from the first fastening zone on the axis of rotation, wherein set screws spaced at regular intervals over the circumference of the rotatable body and are used to position the rotatable body relative to the axis of rotation. Preferably, the central bore of the rotatable body in the area of overlap has a diameter larger than the diameter of the axis of rotation contained therein other than in the first fastening zone.
