<p>The audio-visual projection system consists of a cassette recorder-player with combined projection synchroniser and a slide projector (5). The two elements are combined to form one arrangement mounted inside a case (2) where they are arranged so that running of the tape contained in the cassette (6) permits the playing of a recording and the automatic triggering of a slide projected in synchronism with the recording. The case (2) is fitted with a removable protective cover, and a handle which enables the case to be carried. The slide projector is fitted with an automatic magazine, image changing being controlled by the cassette synchroniser.</p> |
