Object positioning arrangement by causing hammer-like knocks of piezo-electric element against plot surface of plot block, whereby piezo-electric element and/or plot block are fastened to object

摘要

A piezo-electric element (3) controlled by a control unit positions an object (2) relative to a base (1). The movement of the object is caused by hammer-like knocks of the piezo-electric element against a plot surface (41) of a plot block (4), such that the piezo-electric element and/or the plot block are attached to the object. The piezo-electric element is a multi-layer element formed from at least two layers of piezo-electric materials.
