CAMERA SHUTTER DEVICE AND OPTICAL APPARATUS HAVING THE SAME
First Claim
1. A camera shutter device, the device comprising:
- a core including a first rod and a second rod, each arranged in parallel with the other, and one of which is wrapped by a coil, a first distal end formed at the first rod to generate an electromagnetic force line, and a second distal end formed at the second rod to generate an electromagnetic force line;
a magnet arranged in opposition to the first and second distal ends to linearly and reciprocally move between the first and second distal ends;
a slider for opening and closing a shutter blade in a case the magnet linearly and reciprocally moves between the first and second distal ends, wherein each area of the first and second distal ends is larger than each cross-sectional area of the first and second rods.

Abstract
A camera shutter device and an optical apparatus having the same are disclosed, wherein the device includes a core including a first rod and a second rod, each arranged in parallel with the other, and one of which is wrapped by a coil, a first distal end formed at the first rod to generate an electromagnetic force line, and a second distal end formed at the second rod to generate an electromagnetic force line, a magnet arranged in opposition to the first and second distal ends to linearly and reciprocally move between the first and second distal ends, a slider for opening and closing a shutter blade in a case the magnet linearly and reciprocally moves between the first and second distal ends, wherein each area of the first and second distal ends is larger than each cross-sectional area of the first and second rods, such that miniaturization and thinning of the shutter device can be realized, and generation of trembling phenomenon can be prevented during an opening/shutting operation of the shutter blade.
