Abstract:
1. A lens adjusting device comprising: an optical module; a driver module including a seat, at least one magnet and at least one winding, a shaft and at least one column extending from the seat, an axis of the at least one column being perpendicular to that of the shaft, the at least one winding mounted on the at least one column, the optical module being rotatable relative to the shaft, the at least one magnet being fixed on the optical module, the at least one magnet and the at least one winding being positioned at the same side of the optical module, whereby when a variable current is applied to the at least one winding, a magnetic field forms at ends of the at least one winding, magnetic forces between the magnetic field and the at least one magnet driving the optical module to rotate.
