LENS MODULE OF AN IMAGING DEVICE AND A METHOD OF USING THE SAME

摘要

PURPOSE: A lens module and method of use of image sensing device are provided to miniaturize the lens module by increasing the administration of the shutter movement and to reduce the thickness of image sensing device. CONSTITUTION: The lens module of image sensing device includes: a lens barrel plate(10); a shutter plate(12); and a elastic device(14). The lens barrel plate is formed to drive the lens to follow to the optical axis. The lens barrel plate includes: first center hole which the lens barrel plate is arranged with the lens barrel plate silver optical axis; and more than one guide posts(104) perpendicularly arranged in the surface of the lens barrel plate is included. The shutter plate includes the second hole and one or more grooves(124) arranged with the optical axis. One or more grooves facilitates the movement of the guide post. The elastic device respectively copes with the guide post and groove. The elastic device is pressurized when the external force is added in the lens barrel plate and shutter plate and is removed from the lens barrel plate by the recovered elastic device when the external force is removed.
