The camera shutter device includes a pair of cores, each wrapped by a coil and having a distal end facing the other, wherein each coil is formed at the distal end with an electromagnetic force line generating unit. A magnet comprising a first magnet and a second magnet is interposed between the pair of cores. The magnet linearly and reciprocally moves in a direction perpendicular to the electromagnetic force line generating unit, and a slider opens and shuts a shutter blade as the magnet linearly and reciprocally moves, whereby miniaturization and thinning of the shutter device can be realized, and an opening/shutting operation can be stably performed. | 08-25-2011 |
20110206364 | CAMERA SHUTTER DEVICE AND OPTICAL APPARATUS HAVING THE SAME - 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. | 08-25-2011 |
