Drive for a checking unit, in particular for checking of DVDs

摘要

The invention relates to a rotary driving device for a test station for testing a flat data carrier, in particular a CD, DVD, CD'R lying on a conveyor and transported to the inspection station and dissolved for testing this and during testing about an axis perpendicular to the flat side is rotated and scanned. According to the invention it is proposed that the rotary drive device has at least one axially fixed and driven in the direction of rotation recording for the disk, which is arranged on the upper side of the conveying means that with respect to the mount on the underside of the conveying means, a movable towards the receiving elevation means on is provided to the underside of the conveyor such that the lifting means the data carrier from below detected detached from the conveyor and moves in the direction of the receptacle, the receptacle is provided with holding means which hold the disc at least during testing in the receptacle. The release of the data carrier from the conveying means is independent of this, and the rotational movement can be performed with high accuracy without play yet.
