Abstract
A lens moving apparatus is disclosed. The lens moving apparatus includes a bobbin equipped with at least one lens, a coil and a driving magnet arranged opposite to each other for moving the bobbin in an optical axis direction of the lens through interaction therebetween, a first circuit board for supplying electric current required by the coil, and a cover can and a base coupled to, contacted to, supported at, fixed to, or temporarily fixed to each other for forming a space in which the bobbin, the driving magnet, and the first circuit board are received, wherein the cover can is connected to a second circuit board having an image sensor mounted thereon.
Claims19
A lens moving apparatus comprising:
- a housing member;
- a bobbin disposed in the housing member;
- a coil disposed at an outer surface of the bobbin;
- a driving magnet disposed on the housing member and arranged opposite to the coil, wherein the driving magnet comprises a first driving magnet and a second driving magnet opposite to the first driving magnet;
- a cover can comprising an upper surface, four side surfaces extending from the upper surface, and a recess formed at a first side surface of the four side surfaces;
- a base fixed to the cover can;
- a first circuit board disposed on a side surface of the base corresponding to the recess of the cover can and configured to supply electric current to the coil;
- and
- a sensing unit sensing a displacement of the bobbin in an optical axis direction, wherein the sensing unit is coupled to the first circuit board,
- wherein the first circuit board comprises a plurality of terminals including a first ground terminal, the first ground terminal electrically connecting the cover can to a ground;
- wherein the first ground terminal is disposed on a terminal surface opposite to the first side surface of the cover can;
- and
- wherein the first circuit board is disposed on a lateral surface of the housing member such that the first circuit board is placed between the cover can and the lateral surface of the housing member, in a horizontal direction perpendicular to the lateral surface of the housing.
