| 摘要 |
The invention relates to a hand receiver (12) mounted on an x-y-z linear guiding flexion- and torsion-resistant guide extending in a Cartesian coordinate system and consisting of three guiding rails (20, 24, 28) which are pairwisely perpendicular with respect to each other and sliding with respect to each other in the direction of axes x, y and z. Path-signal transmitters detect the translatory movement components of the receiver (12) in the direction of the axes x, y and z of the guiding rails (20, 24, 28).
