| 摘要 |
The invention relates to a transfer mechanism for transferring a specimen ( 2 ) from a first position in a first holder ( 40 ) to a second position in a second holder ( 10 ) and/or vice versa, each holder ( 10, 40 ) equipped to detachably hold the specimen, the transfer of the specimen between the holders taking place in a transfer position different from the second position, characterized in that when the specimen is transferred between the holders ( 10, 40 ) a mechanical guidance mechanism positions the holders with a mutual accuracy higher than the mutual accuracy in the second position, and said mechanical guidance mechanism not positioning at least one of the holders ( 10, 40 ) when the specimen is in the second position. The mechanical guidance mechanism may comprise extra parts ( 50 ). At least one of the holders ( 40 ) may be equipped to hold a multitude of specimens.
