摘要： A lens drive device includes a lens movable body provided with a lens and a drive mechanism for moving the lens movable body from a home position in an optical axis direction of the lens. The drive mechanism includes a magnet and a plurality of coils which is disposed so that the magnet is interposed in the optical axis direction of the lens. An electric current is supplied to the plurality of the coils in a reverse direction to a direction of an electric current, which is supplied to the plurality of the coils for moving the lens movable body, for restricting movement from the home position of the lens movable body. Therefore, swinging and rattling are hard to occur in the lens movable body and thus its impact resistance can be enhanced.

摘要： A lens drive device formed in a substantially quadrangular shape may include a movable body holding a lens, a fixed body movably holding the movable body, and a drive mechanism for driving the movable body in the optical axis direction. The drive mechanism may include first drive magnets respectively disposed on four side faces of the lens drive device, a second drive magnet for restraining inclination which is disposed on at least one of four corners of the lens drive device, and a drive coil which is wound around in a substantially octagonal shape. Magnetic flux passing through the drive coil at one of the four corners of the lens drive device is different from magnetic fluxes passing through the drive coil at the other three corners, or magnetic fluxes passing through the drive coil at two corners adjacent to each other of the four corners of the lens drive device are different from magnetic fluxes passing through the drive coil at the other two corners.

摘要： A position detecting device for detecting a position of a movable body which is moved by a drive system having a rotation body includes a magnetic part having an N-pole and an S-pole on a face of the rotation body and a sensor chip having at least a magneto-resistive element. The face of the rotation body is perpendicular to the rotation shaft of the rotation body and the sensor chip is provided so as to face the magnetic part for detecting a variation of magnetic field by the magneto-resistive element when the magnetic part is rotated with the rotation body. A little space is required for mounting the sensor chip having the magneto-resistive element and therefore downsizing can be attained.
