Abstract
A positioning table device which includes a flat table supported so as to be displaceable both angularly and linearly in a plane. Three pushers having end faces abutting respective rollers are provided such that linear movements of the pushers in a plane parallel to the plane of the table in different reciprocal directions allows exact positioning and rotational movements of the table with any arbitrary position on the table as the center of rotation. In the preferred embodiments, the rollers are rotatable about axes of rotation perpendicular to the plane of the table and two of the end faces are parallel, the third being perpendicular thereto.
