ABSTRACT:
An arrangement for loading record discs of different diameters for selectively recording and playback purposes. A fixed base member is provided with a depression that has a rim corresponding to a record disc of larger diameter. This rim protects the record disc against displacement. The depression has a central region with a recess which holds a raisable and lowerable rest. Three supports are mounted on the rest and are positioned on a circle which has a diameter that corresponds to the diameter of the smaller disc. The three supports secure the smaller record disc against displacement while, at the time, they serve for supporting the larger record disk. The smaller disc and the larger disc are both brought into an operating position on the base member by the raisable and lowerable rest. This base member is, at the same time, free of guide tracks. The raisable and lowerable rest is disc-shaped, and is held by a pivotable arm.
