Abstract:
A stage apparatus, comprising:a table disposed above said base so as to oppose to said base; an X-axis-direction table support mechanism portion disposed between said base and said table for supporting said table in a state that said table is capable of moving in an X-axis-direction within a two-dimensional plane; a Y-axis-direction table support mechanism portion disposed between said base and said table for supporting said table in a state that said table is capable of moving in a Y-axis-direction within a two-dimensional plane; an X-axis-direction linear guide portion formed on an upper surface of said base and extending in said X-axis-direction; a Y-axis-direction linear guide portion formed on said upper surface of said base and extending in said Y-axis-direction; an X-axis-direction movable member provided so as to move along said X-axis-direction linear guide portion and connected to said Y-axis-direction table support mechanism portion; a Y-axis-direction movable member provided so as to move along said Y-axis-direction linear guide portion and connected to said X-axis-direction table support mechanism portion; an X-axis-direction straight drive mechanism fixed to said base for driving said X-axis-direction movable member; and a Y-axis-direction straight drive mechanism fixed to said base for driving said Y-axis-direction movable member, wherein said X-axis-direction linear guide portion and said Y-axis-direction linear guide portion are arranged in a rectangular cross positional relation forming a roughly â€œ+â€  shape.
