Phonograph device
摘要:
An audio-visual phonograph device including a visual image projection system is provided which includes a case for the phonograph device having a lid that serves as a screen for the projection of images formed on a flat disc. The phonograph device further includes a variable speed turntable and a pick-up tone arm employed to reproduce the audio message on the records. The turntable is synchronized with a carrier onto which the visual image disc is removably mounted. The carrier rotates in synchronism with the turntable advancing a continuous image that is projected onto the screen in a timed relation with the correlated audio message.
