Patent ID: 7204033

Claim:
A device having a removable probe system, a permanent magnet, and a stylus instrument that includes a probe base and a mechanical lever arrangement, said device generating signals which represent information about a deflection of the probe system, the probe system being connectable to the stylus instrument by an attractive force of the permanent magnet and being separable from the stylus instrument by the lever arrangement, characterized in that: the probe system is connected to the probe base by first and second spring parallelogram systems arranged functionally perpendicularly to one another so that the probe system is deflectable with multiple degrees of freedom; and prior to a removal of the probe system through a displacement motion thereof, the probe system, may be transferred into a replacing position wherein the lever arrangement increases an air gap proximate the permanent magnet for reducing the attractive force which acts between the probe system and the stylus instrument, to facilitate the removal of the probe system from the stylus instrument.
