t player of this type are attached, so is also further enlargement of the engine cowling is unavoidable as the bearing of each pickup arm is attached to the top of a portion of the engine cowling, which extends around the turntable.

The invention is based on the task of creating a pickup arm that has the various above solves mentioned problems of the prior art, which enables the reduction of the dimensions of the turntable or eliminates the need to increase the size of the turntable, and also completely eliminates cumbersome operations or machining involved in attaching the pickup arm.

The solution to this problem is characterized in claim 1

According to the invention, the attachment of the pickup arm to the engine cover or the removal of the same can be achieved ben can be carried out extremely simply without the need for any tedious measures · It is also possible to select a suitable mounting location in accordance with the length of the pickup arm, and the overhang can be set freely. Furthermore, integrated Pickup arms can be easily replaced, and the Performance of a pickup arm can be based on comfortable Can be compared since two or more pickup arms can be easily attached to a single turntable. Another advantageous effect that can be achieved with the invention is that the dimensions of the base for the pickup arm are due to its novel construction can be reduced

In the drawings, the reference numeral 1 denotes a cast or pressed base, which has a channel-shaped area 2 which can be plugged onto an edge area 9a of an engine casing 9 receiving support 8a. The channel-shaped area 2 and the vertical bore 3 are provided with screws 4 and 5 , which are used to fasten the base 1 to the edge region 9a of the engine casing 9 and to fasten the bearing bracket 8a in the bore 3. To prevent damage to the rear side At the edge area 9a of the engine casing, the tip of the screw 4 is provided with a protective cap 6.

By tightening the screw 5 against the carrier 8a inserted into the bore 3 of the base 1, which is the one pickup arm 7 supporting bearing 8 carries, and by tightening the screw 4 against the Äandbereich 9a of the engine cladding
