ABSTRACT:
A driving apparatus for moving an object. The apparatus includes a first actuator which drives the object in X and Y directions, a second actuator which drives a reaction force counter which receives a reaction force generated when the first actuator drives the object, and a controller which controls the second actuator on the basis of X- and Y-direction positions of the object and X- and Y-direction accelerations of the object so as to cancel, by the second actuator, the reaction force to be received by the reaction force counter when the object is driven by the first actuator.
