Hollow magnets are disposed on an outer peripheral side of the lens and have magnetized portions alternately magnetized to different poles in the circumferential direction. A cylindrical rotor is disposed rotatably with respect to the magnets, made of a soft magnetic material, and is comprised of magnetic pole portions opposed to the magnetized portions of the magnets. A coil energizes the magnetic pole portions of the rotor. A stator fixes the magnets and the coil. A conversion unit adapted to convert rotating movements of the rotor into forward and backward movements of the lens along the optical axis. The magnets have breaks formed along the optical axis, and the guide bar is disposed in the break of the magnets. | 2009-09-03 |
| 20090219637 | DRIVE SYSTEM, DRIVE MODULE AND REARVIEW MIRROR UNIT FOR A MOTOR VEHICLE - A modular drive system, in particular for a driven angular adjustment of a rearview mirror support of a motor vehicle, comprising at least two drive modules, each provided with a housing with an electric motor and a drive portion driven by the electric motor, and a drivable portion for cooperation with a drive portion of another drive module, further comprising coupling means for attaching two drive modules to each other with one rotational degree of freedom by cooperation of a drive portion and a drivable portion, respectively. | 2009-09-03 |
