Object positioning arrangement, such as for microscopy, or similar, having device for producing hammer-like knocks against plot block for shifting object relative to base

摘要

A device (10) produces hammer-like knocks against a plot block (4) for shifting the object (6) relative to a base (7), whereby both the knocking device and the plot block are fastened to the object. The knocking device includes preferably an electric coil (12) which encloses a pestle concentrically. The electric coil is preferably composed of two adjacent single coils (15; 16).
