ABSTRACT:
In an object holder comprising an X-Y translation mechanism, both movements are determined by transporters which are separately moved across a supporting face of a supporting plate under a pressure in a sliding fashion. The pressing force is preferably realized by means of permanent magnets which are mounted on the transporters and which bear on the supporting face of the supporting plate by way of preferably ductile spacers. A device for rotation and/or tilting can be simply added by rotating and/or tilting the entire supporting plate with the X-Y translation mechanism.
