A device for turning an object through a predetermined angle about an axis (1) is disclosed. A means (5) for supporting this object is reciprocatingly movable, in particular in the vertical direction, in relation to a frame (16) along the axis (1) as well as turnable about the latter. A driving means (2) is connected to the supporting means (5) in order to produce the reciprocating movement thereof. A cam guide mechanism (11, 28), which is disposed between and connected to the frame (16) and the supporting means (5), is so designed that a linear force generated by the driving means (2) in order to produce the reciprocating movement of the supporting means (5) is partly converted to a turning force acting on the supporting means, such that the latter is turned through the predetermined angle during a cycle of reciprocating movement. The cam guide mechanism itself is also covered by the invention.
