发明名称 Still image slide with sound track control
摘要 Means for providing stationary images from slides and sound related to these images include a retainer for insertion of a slide, an endless taut magnetic tape mounted within the retainer, and stationary magnetic heads that impose sound tracks on the tape and reproduce such sound tracks. Control circuitry connected to the heads provide a group of sound tracks for each image of a slide in predetermined sequential order.
