Abstract: A camera shutter device and an optical apparatus having the same are disclosed. 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.
