ABSTRACT:
A positioning table includes a table member having a load plane, a supporting device for movably supporting the table member within a plane parallel to the load plane and, first, second, and third slide blocks located around the table member in a freely movable fashion toward and away from the table member. The first and second slide blocks move in directions parallel to each other, and the third slide block moves in a direction perpendicular to the moving directions of the first and second slide blocks. First, second, and third rollers project from a peripheral edge of the table member and are rotatable about axes perpendicular to the load plane. The first, second, and third slide blocks are pressed into contact with the corresponding first, second, and third rollers, and the first, second, and third rotary cams abut against the corresponding first, second, and third slide blocks at opposite sides to where the first, second, and third slide blocks are respectively pressed into contact with the first, second, and third rollers.
