<p>PURPOSE:To provide a mobile table which possesses a compact shape and permits the rectilinear shift and the revolutional movement. CONSTITUTION:The first table A is supported on the second table B through a thrust bearing, and the second table B is installed on the third table C through the rectilinear guides 5 and 5. A composite coupling 9 for allowing the revolution for the first table A and the slide for the second table B is installed between the side 7a of the first table and the first driving device 10, and the second driving device 22 is connected on the side 7b of the first table A through a slide coupling 20 and a turning coupling 21. The third driving device 30 for driving the first table and the second table along the rectilinear guide 5 is connected on the side of the third table C.</p> |
