    摘要: Stabilization of a stage in a movable stage apparatus is enhanced, and increasing in size of the movable stage apparatus is suppressed. A reaction force cancel system is provided in the movable stage apparatus where a stage moves on a surface plate installed on a floor via a vibration-isolating spring, and cancels a reaction force generated on the surface plate upon movement of the stage. The reaction force cancel system includes a reaction force canceling actuator for applying a counter-thrust that is a force for reducing the reaction force to the surface plate. The reaction force canceling actuator is arranged at a lower position than a top surface of the surface plate so that the surface plate hangs over the reaction force canceling actuator.
