  • Lens drive unit
    Patent number: 10514522
    Abstract: A lens drive unit that prevents an actuator from being inclined is provided. In the lens drive unit, when a lens frame is displaced in a direction orthogonal to a direction in which the actuator extends and contracts with respect to a base member by, for example, impact from an outside of the lens drive unit, a drive shaft of the actuator abuts on a first lateral wall and a column, so that the actuator is prevented from being inclined with respect to the base member.
    Type: Grant
    Filed: July 3, 2017
    Date of Patent: December 24, 2019
    Assignee: TDK CORPORATION

  • Lens drive unit
    Patent number: 10429606
    Abstract: A lens drive unit that offers enhanced reliability in connection between an actuator electrode and an electric wire is provided. In the lens drive unit, an actuator has a weight housed in an holding portion of a base member and is thereby fixed in the base member. Electrodes on a lateral surface of the weight directly contact respective terminal electrodes on an inner lateral surface of the holding portion, so that an electrical connection is established therebetween. The arrangement enhances reliability in connection between the actuator electrodes and the terminal electrodes.
