ABSTRACT:
An audio-visual reproducing device is disclosed which utilizes a program unit having a structure for producing an audio signal and carrying a plurality of visual representations. The program unit is mounted in the device so that a rotatable pick-up is moved along the structure for producing an audio signal in order to obtain an audio output. As such an audio output is obtained a separate optical structure projects a single one of the visual representation so that such representation may be observed.
