Patent ID: 8218956

Claim:
A driving system comprising: a fixed substrate; a coil unit which generates an electromagnetic force if an electric current applied; a magnet unit formed under the fixed substrate to face the coil unit; and a plurality of driving units which are interconnected with each other on the fixed substrate, and which are moved respectively in parallel direction with respect to a surface of the fixed substrate in accordance with an interaction between the electromagnetic force and a magnetic force of the magnet unit, if the electric current is applied, wherein the plurality of driving units comprise: a first driving unit movable in a first direction which is parallel to the surface of the fixed substrate; and a second driving unit connected to the first driving unit to be moved in accordance with the movement of the first driving unit, the second driving unit movable in a second direction which is parallel to the surface of the fixed substrate and perpendicular to the first direction, wherein the driving system further comprises: a first spring unit to connect the first driving unit and the fixed substrate; and a second spring unit to connect the first and second driving units with each other.
