ABSTRACT:
An optical scanner has focusing elements rotatable about a fixed axis. The elements are each mounted on a flexible radially extending suspension arm. A magnet is carried by each arm and passes a coil extending along the path of the elements. Current to the coil is controlled to induce movement of the arm in a direction parallel to the axis of rotation and effect focusing of the elements.
