Photography device with anti-shake function

摘要

A photography device with anti-shake function for sensing camera shake and moving a lens toward a direction to correct the camera shake when photographing an object so that the object may be clearly photographed. A coil and a magnet are included in the invention, and the coil moves in a direction perpendicular to the optical-axis of the lens as a result of magnetic fields generated by the magnet and the coil when electric power is applied to the coil.

主权项

1. A photography device with anti-shake function, comprising:
a housing; a first blade disposed in an inside of the housing and including a lens therein, the first blade being movable in an up and down direction; a first coil member wound around outside of the first blade; a first elastic member electrically connected with the first coil member and elastically supporting the first blade in the up and down direction; a second blade disposed horizontally movably in an inside of the first blade and mounted with a second coil member in an outside surface thereof; a second elastic member formed of a vertical wire spring, an upper end of the second elastic member being connected to the first blade and a lower end of the second elastic member being connected to the second blade; and a magnet disposed between the first blade and the second blade, wherein the first blade and the second blade moves up and down together by interaction of a first electromagnetic field generated when power is applied to the first coil member with a magnetic field generated in the magnet, and the second blade moves horizontally independently from the first blade by interaction of a second electromagnetic field generated when the power is applied to the second coil member with the magnetic field generated in the magnet.
