摘要:
There is provided an alignment apparatus of rotating a table by translational driving to be able to operate the table in XYθ, Yθ, or θ accurately.4 pieces of drive systems for driving a table (4) mounted with an object (5) includes a translational freedom degree portion (11), a translational drive portion (12), and a rotational freedom degree portion (13), further, an alignment apparatus is made to be able to return to an original point by providing a motor (1) and a detecting apparatus (2) at a machine fixing apparatus (41), accurately fixing the table (4) by the machine fixing apparatus (41) by using a first positioning apparatus and a second positioning apparatus, and a first position fixing apparatus and a second position fixing apparatus, and storing a detecting apparatus reference position at a detecting apparatus reference position storing apparatus (44).

To be able to restrain a height of a machine even when the machine is large-sized and smoothly move a table in XYθ directions.An alignment apparatus includes two translational freedom degree guide portion (13), one rotational freedom degree guide portion (12), a translational drive/translational/rotational freedom degree mechanism module (6) including a linear motor provided at one of the translational freedom degree guide portion (13), a machine base portion (7), a reference generator portion (8), a two-dimensional position sensor (9), a calculating portion of compensation value (10). At least three of the translational drive/translational/rotational freedom degree mechanism modules (6) are uniformly arranged to a table (4).
