Abstract: PROBLEM TO BE SOLVED: To reduce deflection of a substrate by providing substrate bearers to be displaced to a protruding position protruding from a substrate support to a lifter of a non-protruding position at four or more positions in an extending direction parallel to the substrate supported to a table. SOLUTION: Lifters 48 are disposed on a table 44 to lift up or down a substrate 12 to or from the table 44. The lifters 48 have a plurality of substrate bearers 50 projectable from or retractable to an upper surface of the table 44.
