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 a disadvantage of having a large number of components with a complex operation structure, thereby using an unnecessarily large area of installation space, and an increase in power transmission loss leads to an increase in battery consumption
[0008] Another disadvantage is that multiple gears are used in the shutter mechanism of a conventional camera, and if a complex linkage mechanism is used, the quality of the captured image will be degraded due to the slow response speed of the shutter, so the shutter mechanism should be Has a high shutter speed that instantly turns on and off the light bouncing off the subject

A camera shutter device and an optical apparatus having the same are disclosed. The shutter device includes a core wrapped by a coil, wherein a first distal end and a second distal end of the core are arranged in parallel, and when a voltage is applied to the coil, the first and second distal ends exhibit a mutually opposite polarity with respect to each other. A magnet is arranged with a side facing the first and second distal ends of the core for linearly and reciprocally moving between the first and second distal ends. In addition, a slider opens and closes a shutter blade as the magnet linearly and reciprocally moves. Thus, the driving unit of the core, magnet, and slider can be miniaturized and thinned, and a reciprocatively moving distance of a magnet can he minimally shortened to quicken the opening / shutting operation.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 10-2010-0015813 filed 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, as the number of pixels in camera-embedded mobile devices has increased, optical image devices including camera-embedded mobile devices have become diversified and high-quality (eg, capable of taking high-quality photos). Accordingly, mobile devices incorporating cameras need to employ shutters configured to open and close lens nozzles such as those found in conventional cameras. [0005] If suc...
