Abstract
An aperture module includes a base; a rotor rotatably disposed with respect to the base; a plurality of blades interlockable with the rotor rotating to form incidence holes of various sizes; a rolling portion, including a plurality of rolling balls, disposed between the base and the rotor; and an aperture driver including a magnet portion disposed on one of the base or the rotor, and a coil portion disposed to face the magnet portion. The magnet portion includes a first aperture magnet and a second aperture magnet spaced apart from each other. Attractive force acts on either one of the first aperture magnet or the second aperture magnet in at least two directions intersecting each other.
Claims19
An aperture module comprising:
- a base;
- a rotor rotatably disposed with respect to the base;
- a plurality of blades interlocked with the rotor configured to rotate to form incidence holes of various sizes;
- a rolling portion, including a plurality of rolling balls, disposed between the base and the rotor;
- and
- an aperture driver including a magnet portion disposed on one of the base or the rotor, and a coil portion disposed to face the magnet portion,
- wherein the magnet portion comprises a first aperture magnet and a second aperture magnet spaced apart from each other, and
- wherein attractive force always acts on either one of the first aperture magnet or the second aperture magnet in at least two directions intersecting each other.
A camera module comprising:
- a lens module movable along three axes perpendicular to each other;
- a housing accommodating the lens module;
- and
- an aperture module, coupled to the lens module and movable with the lens module, comprising:
- a base;
- a rotor rotatably disposed with respect to the base;
- a plurality of blades interlockable with the rotor rotating to form incidence holes of various sizes;
- an aperture driver including a magnet portion disposed on the rotor, and a coil portion disposed on the base;
- and
- a pulling yoke portion disposed on the base to face the magnet portion,
- wherein the magnet portion comprises a first aperture magnet and a second aperture magnet, spaced apart from each other,
- the pulling yoke portion includes a first pulling yoke facing the first aperture magnet, and a second pulling yoke facing the second aperture magnet, and
- an area of the first pulling yoke facing the first aperture magnet is larger than an area of the second pulling yoke facing the second aperture magnet.
