ABSTRACT:
Loading a disc onto the turntable there are provided transfer means comprising a frame and a disc holder which can be slid into and out of said frame and which can be lowered therewith axially past the turntable into a lower position in which the disc is supported on the turntable and is clear of the disc holder. The disc holder comprises a plurality of spring-loaded catches which are arranged circumferentially around the disc and which are movable in the radial direction. There is provided a plurality of stationary upwardly directed release elements with conical end portions, which, relative to guide means for the transfer means and a disc-pressure member, occupy positions such that the catches are released when the transfer means are lowered past the turntable, whereupon the discpressure member urges the disc against the turntable. Near each catch the disc holder has a surface for supporting the disc and the disc holder is open at the upper side.
