摘要: The speed and precision in positioning a moving table in the X-axis and Y-axis directions is enhanced dramatically. An X-Y stage apparatus is provided, in which a moving table is supported relative to a stationary base, with slight displacements made possible within the XY plane, and in which a component mounted and placed on the moving table can be positioned within the XY plane. The X-Y stage apparatus includes an elastic hinge that is flexible only in one or two direction among the X-axis, Y-axis, and Z-axis directions, and rigid in directions of the other axes. The moving table is supported relative to the stationary base with slight displacements made possible in the XY plane, using an elastic deformation of each of the elastic hinges in the flexible direction. Furthermore, the moving table can be slightly displaced within the XY plane, using an X-axis linear motor, and a Y-axis linear motor.
