Problems solved by technology

[0009] However, a disadvantage of a conventional shutter driving device for a camera module constructed as described above is that since the camera module 1 must define a space in which the shutter blade 5 can be rotated to open and close the lens opening 4
This constitutes a limitation in reducing the size and volume of the camera module 1
The miniaturization and slimness of the camera module are limited concomitantly

Embodiment Construction

[0034] Referring to FIGS. 3 and 4 , a shutter driving device 10 for a camera module according to a first embodiment of the present invention includes a lens housing 20 , a pair of shutter blades generally indicated by reference numeral 30 , and a pair of shutter driving parts 40 . The lens housing 20 is configured to allow the shutter blade 30 to slidably move therein. Shutter blades 30 are disposed within the lens housing 20 such that they are slidably movable along the length direction of the lens housing to open and close the lens opening 4 of the lens module 3 . The pair of shutter driving parts 40 are connected to the shutter blades 30 through respective rotary links 50 and placed under the shutter blades 30 . Each shutter driving section 40 has an electromagnet 41 and a permanent magnet 42 positioned between magnetic poles of the electromagnet. The permanent magnet 42 is connected to the rotary link 50 and is rotated by a magnetic field generated when current is applied...

Abstract

A shutter driving apparatus for a camera module has a shutter driving section constructed to slidingly move shutter blades provided to a camera lens module in both sideward directions to thereby open and close a lens opening. The shutter driving apparatus comprises a lens housing; a pair of shutter blades provided to the lens housing to be slidingly moved in a lengthwise direction of the lens housing to thereby open and close a lens opening of the camera lens module; and a pair of shutter driving sections respectively connected to the shutter blades via rotation links and each being configured for creating a pair of electromagnetically-opposite electromagnet poles and having a permanent magnet positioned between the poles such that a permanent magnet with at least one of the poles and connected to the rotation link is rotated due to a magnetic field created as current is applied to the electromagnet, to slidingly move an associated shutter blade.

Description

technical field [0001] The present invention relates to a structure for sliding shutter blades, in particular, to a shutter driving device for a camera module that slidably moves a shutter blade provided to a camera lens module in two lateral directions , to open and close the lens opening. Background technique [0002] As generally known in the art, a camera module is used for a video camera, an electronic still camera, a PC camera terminal, a camera phone, etc., to recognize an image. [0003] These days, the size of the camera module and the photographed image are shrinking with the development of high-precision technology, and various camera modules are disclosed in the prior art, which are miniaturized so that each camera module can be kept in a The user can take pictures of objects without the aid of a tripod or the like in hand. [0004] In contrast, recently, by attaching a camera module to a portable terminal, it is possible to perform visual conversion with a cor...
