Abstract
A lens drive device in which a lens holder forming a moving unit and connection wires for connecting a plurality of drive coils electrically are integrally molded, and a method for manufacturing the lens drive device. This lens drive device is constructed to include: an actuator unit in which four wire-form elastic members made of a metal are molded integrally with the lens holder and an actuator base and in which connection wires for connecting a printed circuit board A coil and a printed circuit board B coil are integrally molded; and a suspension base having a pair of yokes fixing a pair of magnets arranged to confront each other through a predetermined magnetic space.
Claims7
A lens drive device comprising:
- a lens holder to which an objective lens and a plurality of drive coils are fixed, and
- a plurality of wire-form elastic members made of a metal, for supporting said lens holder, in which said drive coils are energized through said wire-form elastic members,
- wherein said lens holder is molded out of a resin integrally with connection wires for connecting said drive coils electrically.
A lens drive device in which a lens holder and a suspension base are integrally molded out of a resin on the two end sides of a plurality of wire-form elastic members made of a metal, in which an objective lens and a plurality of drive coils are fixed on said molded lens holder, and in which said drive coils are energized through said wire-form elastic members,
- wherein said wire-form elastic members are provided at their one-side ends with connection terminals which are partially exposed from said lens holder and connected with said drive coils, and
- wherein connection wires for connecting said drive coils are integrally molded while being contained in said lens holder.
A suspension unit for a lens drive device, comprising a lens holder and a suspension base,
- wherein said lens holder and said suspension base are integrally molded out of a resin on the two end sides of a plurality of wire-form elastic members made of a metal, and
- wherein connection wires for electrically connecting said drive coils to be fixed on said lens holder are integrally molded while being contained in said lens holder.
A method for manufacturing a lens drive device, in which a lens holder for fixing an objective lens and a plurality of drive coils to be electrically connected through connection wires thereon and a suspension base are jointed through a plurality of wire-form elastic members made of a metal, to support said lens holder movably and to energize said drive coils through said wire-form elastic members, comprising:
- a first step of positioning said wire-form elastic members and said connection wires in predetermined positional relations;
- a second step of molding a lens holder of a resin integrally with said wire-form elastic members and said connection wires on one-end side of said wire-form elastic members and a suspension base of a resin integrally with said wire-form elastic members at the other end of said wire-form elastic members;
- and
- a third step of fixing said objective lens and said drive coils on said lens holder and connecting said wire-form elastic members made and the terminals of said connecting parts with the terminals of said drive coils.
