<p>The positioning device includes a body (12) movable by three drives and connected rigidly to three oblong non-parallel guide elements (16, 17, 18) which are each mounted longitudinally displaceable in a translation bearing (19, 20, 21) which can swivel about a swivel axis perpendicular to the plane. Each swivel axis (22, 23, 24) is mounted on a rotor spaced from the rotational axis and parallel to same and the three rotors are arranged axially parallel and rotatable through the drives.</p> |
