Problems solved by technology
[0006] However, due to the reality of requiring a small mobile device limited by installation space and battery consumption, miniaturization of the shutter device including the shutter and other elements for operating the shutter, and reduction of driving power must be given top priority.
[0007] That is, since the conventional shutter device has the disadvantage of having a large number of elements with a complex operating structure, thereby using unnecessary installation space, and the increase in power transmission loss leads to an increase in battery consumption
[0008] Another disadvantage is the use of multiple gears and if a complex linkage is used, the picture quality of the captured image will be degraded due to the slow response of the shutter, since the shutter mechanism should have the ability to open and close instantly from the object High shutter speed for reflected light

The invention discloses a camera shutter device and an optical device having the camera shutter device. The device comprises: a pair of cores wound with a coil, each core facing the other core. And an electromagnetic force line generating unit is formed at its distal end; a magnet interposed between the pair of cores linearly and reciprocatingly in a direction perpendicular to the electromagnetic force line generating unit moving, and the magnet is magnetized into a first magnet and a second magnet; and a slider for opening and closing a shutter blade when the magnet moves linearly and reciprocally, whereby the shutter device can be realized becomes smaller and thinner, and can perform opening / closing operations stably.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of earlier filing date and priority of Korean Patent Application No. 10-2010-0015744 filed on February 22, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] Lectures according to an exemplary embodiment of the present disclosure mainly relate to a camera shutter device that opens and closes a lens nozzle in an optical image device including a camera-embedded mobile device and an optical apparatus having the same (nozzle). Background technique [0004] Recently, with the increase in the number of pixels in camera-embedded mobile devices, optical image devices including camera-embedded mobile devices have become diversified and high-quality, and high-quality pictures can be taken. Therefore, a mobile device embedded with a camera urgently needs to adopt a shutter configured to open and close a lens mouth used in a conventional camera. ...
