Abstract: Drive units for a data medium, e.g. a CD or a DVD, generally comprise a turntable and a clamp. It would be advantageous to provide a drive unit having an improved torque 5 transmission from the rotatable parts of the drive unit to the disc. It would also be desirable to allow a better guiding of the disc into a centered position around the axis of rotation from the supporting surface. To better address one or more of these concerns, an embodiment of the invention provides a drive unit for a data medium, comprising a turntable and a clamp for clamping a data medium onto the turntable, wherein the turntable 10 and the clamp can be moved with respect to each other from an unclamped to a clamped position, and, in the clamped position, the turntable and the clamp comprise a form-fit torque transmission between them.

Abstract: A disk loading mechanism comprises a frame and a roller mounted on a carrier. The carrier is pivotable with respect to the frame to bias the roller onto the disk. It would be advantageous to provide a disk loading mechanism in which the forces exerted on a disk to be inserted in or ejected from a drive unit by a roller providing a movement of the disk are equal for the inserting and ejecting operations. To better address one or more of these concerns it is suggested to provide a disk loading mechanism comprising reduction gears which do not transmit any other than rotational forces onto the roller. Any other forces are accommodated for by the carrier and compensate each other such that they do not have any influence on the biasing of the carrier towards the disk.

Abstract: The invention relates to a device for playing and storing several disc-shaped data carriers to be operated alternately, in particular CDs, CD-ROMs, and DVDs, with a playback unit designed for playing the data carrier and comprising a base plate (5) and a frame (6) which are coupled to one another by means of springs and/or dampers, and comprising a turntable (13) arranged on the frame (6) and designed for accommodating the data carrier and a pressure device for pressing the data carrier onto the turntable (13), while a stacking unit is provided for the intermediate storage of several data carriers, and a loading device is provided for the bidirectional transport of the data carrier between the stacking unit and the playback unit as well as for moving the data carrier into and out of the device. The playback unit is displaceable by means of a worm gear (1) and can be locked in several positions.

Abstract: The device includes two pressure rollers (24,25) mounted on their respective levers (20,21) and brought to bear upon two parallel shafts (36,37), for driving the tape in the forward and backward directions. The magnetic head is fitted to a carrier (2) which moves it into different positions with respect to the path of the tape. An adjustment lever (5), which is rotatable and/or slidable on the head carrier, is coupled to both of the roller levers and moves them into their alternative positions when the tape is reversed. The position of both levers is determined by that of the adjustment lever, in both directions.

Abstract: Handling an information plate includes receiving the information plate at a roller element, the information plate rolling over the roller element; detecting a position of the information plate using a scanning lever, the scanning lever having a scanning edge pressed against an edge of the information plate; driving a transport wheel into rotation based on the detected position of the information plate; exerting a tangential force on the edge of the information plate using the transport wheel; and transporting the information plate into a loading device, the information plate supported by the transport wheel and the roller element.

Abstract: The invention relates to a wrap spring clutch between clutch partners (2, 6), of which the first, inner clutch partner (2) comprises an outer cylindrical surface (2a) about which the loops (4c) of a wrap spring (4) are positioned, and of which the second, outer clutch partner (6) comprises an inner cylindrical surface (8), inside which the loops (4c) of the wrap spring (4) are located, wherein the ends (4d, 4e) or one of the ends of the wrap spring (4) project out of the loop area and form a driving tang (5), which may be actuated by a driver (7) of the second clutch partner. Only the loops (4c1) of a first portion (4a) of the wrap spring (4) are wound with their internal diameters fitting closely under pretension on the outer surface (2a) of the first clutch partner (2). At least part of a first loop (4c2) of a second portion (4b) of the wrap spring (4), adjoining the driving tang (5), exhibits a larger internal diameter in the rest state than the outer surface (2a) of the first clutch partner (2).
