Abstract:
The present invention relates to a shutter device for camera used for small-sized digital equipment and includes a base forming a light transmission hole to expose a film or charge-coupled device (CCD) to laser beam; an electromagnet mounted on one side of the base; a driving arm which is mounted on one side of the electromagnet on the base so as to pivot on the base; a first shutter and a second shutter to open and close the light transmission hole, which pivots on the part of the base in association with the pivoting of the driving arm; and a magnetic which is installed on the driving arm and has the north magnetic pole and the south magnetic pole at opposite ends of the magnetic or on surfaces opposite to the electromagnet. The driving arm drives the first shutter and the second shutter by pivoting in a clockwise or counter-clockwise direction by the attractive force and repulsive force generated between the electromagnet and the magnetic according to the direction of the electric current applied to the electromagnet, the electromagnet includes a bobbin and a coil wound around the bobbin, and each side of the bobbin having opposite poles of magnetic field is disposed adjacent to the north and south pole.
