Abstract
A movable table unit capable of carrying out an operation for rotating a movable table at a position other than an original point and an operation for moving it in parallel after rotating at a predetermined angle by a simple control, capable of moving the rotation center linearly along two axes easily, and further moving the movable table largely along a single axis, is provided. The movable table unit for achieving this object comprises a table base plate, a movable table supported movably on the table base plate, a plurality of moving members joined to a bottom surface of the movable table, a plurality of two-axis guiding systems for guiding each of the moving members along two axes intersecting with each other on the table base plate and for guiding largely along an axis, rotation systems for supporting the movable table or moving members rotatably relative to each of the two-axis guiding systems and a plurality of driving systems for moving each of the moving members selectively along any one of the two axial directions so as to provide the movable table with a linear motion along the two axes and for providing the movable table with a rotation motion around an axis perpendicul…
