ABSTRACT:
A device for the viewing of photo-images and the presentation of sound recordings corresponding to such photo-images, which device may be controlled by the user to provide substantially random access to any photo-image and the sound recording corresponding thereto, is disclosed. A modular construction of such device and its adaptability to either hand-held or projection embodiments is described. A novel tone arm system as well as a novel turntable driving mechanism, a novel disc type record unit and a novel record changing mechanism is disclosed. In addition, a novel stereoscopic system based on the use of two identical views of the field of vision is disclosed and a specific optical system is described. Finally, a method of and means for coordinating a group of photo-images and a group of sound recordings so that selection of a particular photo-image automatically selects the corresponding sound recording is disclosed.
