ABSTRACT:
A movable table has a fixed platen, a movable platen, a plurality of balls for supporting the movable platen over the fixed platen, a retainer provided between the fixed platen and the movable platen for retaining the balls, and a restrictor for restricting the movement of the retainer. The movable platen is moved in one direction by at least two first driving assemblies and is moved in a direction perpendicular to the above direction by a second driving assembly. The first and second driving assemblies are coupled to the movable platen so as to be pivotable and slidable in a direction perpendicular to the direction in which is moves the movable platen.
