Zusammenfassung:	The invention relates to a parallel positioning mechanism, especially for machining and/or manipulation and/or measuring, consisting of a platform for the carrying and/or manipultaion with, for instance, a tool, a workpiece, a measuring device or the like, wherein the platform is connected with the machine frame by means of at least one positioning arm, characterised in that the platform ( 3 ) is joint-connected with at least one sliding guide ( 4 ) via at least three rotatable joints ( 11 ) of which at least two are arranged on a positioning arm ( 6 ) for the connection with the sliding guide ( 4 ), wherein the axes of rotation of the rotatable joints are mutually parallel. The direct connection may be replaced by a plurality of positioning arms ( 6 ), in which case the connection of the platform ( 3 ) with the sliding guide(s) ( 4 ) is achieved by means of at least four positioning arms ( 6 ).
