ABSTRACT:
There is provided a multi-degree-of-freedom positioning mechanism having a guide shaft and first and second moving members movably mounted on the guide shaft. Each drive is connected with the first and second moving members so as to allow the moving members to travel along the guide shaft. The machanism has a pair of foldably joined equally long links, which are pivotally rotatably engaged with the first and second moving members by first and second couplings. Furthermore, one edge of a table is pivotally rotatably engaged with the joint between the mating links of the foldably joined equally long links, to displaceably support the table.
