  • Patent number: 8670195
    Abstract: A lens actuator includes a carrier that is configured to retain a lens; a first AF coil that is disposed in the carrier while wound about an axis perpendicular to a lens retaining surface; first to fourth magnets that are disposed opposite the first AF coil in four directions parallel to the lens retaining surface; a first OIS coil that is disposed opposite the first magnet; and a second OIS coil that is disposed opposite the second magnet. A current is passed through the first AF coil to move the carrier in a vertical direction along an axis. The currents are passed through the first and second OIS coils to a movable unit in front-back and left-right directions. Therefore, weight reduction of the movable unit can be achieved to provide a lens actuator, in which electric power saving can be achieved.

  • Patent number: 7944631
    Abstract: A lens actuator has a carrier, a cover, a first spring, a second spring, a coil, and a magnet. The carrier with a cylindrical shape is provided with a hollow section formed along a first direction, and has a holding section formed on one side of the first direction. The hollow section has a shape configured to mount a lens barrel therein. The cover, which is disposed on the side having the holding section of the carrier, has a supporting section that meets with the holding section of the carrier. The first spring and the second spring make a resilient contact with each of both surfaces in the first direction of the carrier. The coil is circumferentially disposed on the carrier so as to face the magnet. Of the coil and the magnet, one is mounted on the carrier and the other is disposed on the outer or the inner periphery of the carrier.

  • Patent number: 6831241
    Abstract: A touch panel switch having a wide usable operating range and thus a large effective use area and having electrodes disposed opposedly to each other through a spacer installed around the periphery thereof, the spacer formed in an elastic body of 1×105 to 1×107 dyne/cm2 in elastic modulus comprising an insulation layer and an adhesive layer, the insulation layer further comprising a clearance holding part with a uniform thickness and a gradient part with a thickness gradually decreasing from the clearance holding part into a substrate having the electrodes formed thereon.
