Abstract: PURPOSE:To always obtain an X-Y table which can be always positioned at the time of feeding in an accurately perpendicular direction by correcting a moving distance of the table while monitoring the difference of the moving distance to be measured by a first interferometer and the moving distance of a second interferometer, and controlling the movement of the table. CONSTITUTION:This X-Y table is provided with interferometers 4, 4a for measuring the moving distance and interferometers 5, 5a for correcting an inclination at a predetermined interval from the interferometers 4, 4a. It is assumed that the operation is deviated by theta with respect to a direction Y. If the table 1 moves in the direction Y indicated by the arrow, the interferometer 4 starts to measure the moving distance of the table. In this case, the interferometers 4a, 5a measure a distance from the table 1. Then, a difference of counted values of the interferometers 4a, 5a is read by a drive controller, and an output responsive to the difference is sent to a drive source 6. The source 6 operates a driving mechanism 7, finely moves the table in a direction X, and moves the table 1 in a direction for correcting its angle. As a result, since the table can be moved in a perpendicular direction, it can be accurately positioned.
