Patent ID: 7639573

Claim:
A device for handling data media in a storage device comprising: slots for the data media, wherein the openings of said slots are disposed in the storage device in at least two groups offset at an angle with respect to one another; and a robotic unit which can be traversed and positioned in front of the slots in order to remove the data media from the slots by means of a picker, to insert the data media into the slots, and to transport the data media between different slots; wherein the robotic unit can be traversed by means of a toothed wheel driven by a first controllable motor and a toothed linear track along a translational path in a plane and can be turned by means of a second controllable motor engaging in a circular toothing about an axis of rotation perpendicular to the plane; wherein the robotic unit comprises a base plate which can be displaced in a guided manner along the translational path; wherein on the base plate a rotary plate is mounted in such a manner that it can turn about the axis of rotation perpendicular to the base plate; wherein the rotary plate carries the picker; wherein the base plate comprises, concentric to the axis of rotation, a recess within which a toothed wheel is accommodated which is mounted in such a manner that it can turn and is concentric with the axis of rotation; wherein the first motor is disposed on the rotary plate and engages, by means of a pinion, in an outer toothing of the toothed wheel, wherein the outer toothing of the toothed wheel is in engagement with the toothed linear track; wherein the second motor is disposed on the rotary plate and engages, by means of a pinion, in a circular toothing of the base plate; and wherein said circular toothing is concentric to the toothed wheel.
