A movement mechanism comprises a substantially spherical holder and a substantially bowl-shaped ring, which, when inserted into each other, are rotatable relative to each other about at least one first axis (A), which lies in a plane which is substantially parallel with the top face of the holder. Driving means are provided for enabling movement of the holder relative to the ring. These driving means comprise a non-straight driving rod bearing-mounted in the holder and means for activating the driving rod. The driving rod is further connected with a driving part, which is rotatably mounted in a recess in the ring relative to a second axis (B), which second axis (B) lies in a plane equal or parallel to the top face of the ring, and which second axis (B) lies at an angle of approximately 90° to the first axis (A). |
