Abstract
Abstract Apparatus for automatically playing back with selection recordings in cassettes, the apparatus comprising a stationary circular magazine containing radially disposed cassettes, the centre of the magazine containing a rotating bearing member bearing a playback facility and driven so as to bring the assembly in correspondance with the cassette containing the said recordings and a selector device comprising choice-formulating means is provided. Marks are disposed with which reading heads cooperate so that a correspondance between the position of the marks and the reading heads causes a selector, adapted to set up a choice, to control a drive motor.
