Antriebsvorrichtung für eine optische Abtasteinrichtung

摘要

The apparatus has a threaded spindle (16), where a spindle nut (23) is threaded onto the threaded spindle. A coupling unit (24) is provided for coupling the spindle nut to a scanning device so that the coupling unit provides a Cardan coupling in a Cardan/universal joint manner. The coupling unit has a disc-shaped connection piece (25) for connecting disc-shaped joint plates (26, 27, 28) to the scanning device. The joint plates are arranged between the spindle nut and the connection piece so that the spindle nut, the joint plates and the connection piece are arranged parallel to each other.
