Abstract
This specification discloses a motion picture projector device as audio-visual aid and an audio-visual system using the same. The device uses a film structure including an image information recording zone, a row of perforations along one side edge of the film, and a balance zone juxtaposed with said row of perforations along the one side edge of the film and having various signals recorded thereon in a straight line. These signals include a non-normal projection mode speech information signal, a transfer instruction signal for instructing the transfer of said non-normal projection mode speech signal to a record information member, a transfer stop instruction signal for stopping the transfer, and a reproduce instruction signal for instructing a reproduce mechanism to reproduce the non-normal projection mode speech information signal transferred to said record member. The film structure further includes, on the other side edge thereof, a normal projection mode speech information recording zone which may be reproduced by another reproduce mechanism during normal projection mode. The signals recorded on the balance zone of the audio-visual film structure may be transferred to said record information member during normal projection mode. The signals transferred to the record information member may be reproduced during non-normal projection mode.
