Abstract
A driving apparatus which comprises a stator and two movable elements. The stator includes a first area and a second area. The movable elements can move on the stator. The movable elements include magnets, while the stator includes a coil unit. The coil unit includes a driving coil which independently drives the two movable elements within the first area and the second area, and a swap coil which swaps the two movable elements between the first area and the second area. The coil unit is configured such that the swap coil and at least part of the driving coil are superimposed on each other.
