Abstract:
1. A device for transporting an optical element, the device comprising: a base; a transporting member that supports the optical element and is movably disposed along a predetermined direction with respect to the base; a magnet extending from the base along a movement direction of the transporting member; a coil that is coupled to the transporting member and generates a magnetic field when an electrical signal is applied thereto; a magnetic substrate that is disposed on the transporting member and applies a force to the transporting member toward the magnet due to an action of a magnetic force between the magnet and the magnetic substrate; and a yoke portion that extends from the base to face the magnet, wherein the transporting member is movably disposed along an extension direction of the yoke portion outside of the yoke portion, and the coil is coupled to the transporting member to surround the yoke portion.
