Embodiment Construction

[0033] exist figure 1 In , a first exemplary embodiment of a turntable 1 according to the invention is shown. The turntable 1 has an elongated portion 2 having a hole 3 and serving as a base for receiving a motor shaft 4 of a drive motor 5 . Ideally, the axis of symmetry of the turntable 1 coincides with the axis of rotation 6 of the motor shaft 4 .

[0034] exist figure 1 The right part of the figure shows an enlarged detail of the hole 3 with the motor shaft 4 located therein. The diameter of the hole 3 , which in this exemplary embodiment is substantially cylindrical, is larger than the diameter of the motor shaft 4 over its entire length, so that there is a gap 7 between the wall of the hole 3 and the motor shaft 4 . Due to this gap 7 the turntable 1 can be displaced and tilted with respect to the motor shaft 4 . This allows the turntable 1 to be adjusted in such a way that its axis of symmetry coincides with the axis of rotation 6 of the motor shaft 4 . In addition...

Abstract

The present invention relates to a turntable for a drive for interchangeable storage media in disc form. According to the invention, in the case of a turntable for a drive for storage media in disc form, with a bore for receiving a motor shaft of a drive motor, the diameter of the bore is greater, at least in a partial region of the bore, than the diameter of the motor shaft, so that there is a gap between the wall of the bore and the motor shaft, and the inclination and / or the position of the turntable can be set in relation to the axis of rotation of the motor shaft.

Description

technical field [0001] The invention relates to a turntable for drives of interchangeable storage media in the form of discs. Background technique [0002] Currently, there are many known interchangeable storage media in the form of discs. These are primarily optical storage media, such as various forms of CD (Compact Disc) or DVD (Digital Versatile Disc). However, magnetic storage media in the form of disks (floppy disks) or magneto-optical storage media in the form of disks (MOD, magneto-optical disk) are also known. Drives for storage media of this type generally have a turntable which carries the storage medium in the drive on its support surface and holds it in place with clamps. The turntable is set in rotational motion with the aid of a motor to read from and / or write to the storage medium and is mounted directly on the motor shaft or on its own drive shaft. In the latter case, the turntable is driven by means of a corresponding gear mechanism. [0003] In the cas...
