Abstract

The audio-visual unit has at least one projector and at least one magnetic tape player, each projector containing several independent image sequences and each tape player several independent sound sequences. The projector and tape player are independent, both being connected to a common control circuit, with an input keyboard, for selection of a programme of related image and sound sequences. The selection keys can each be depressed into the active position, to select a required programme sequence, with the remaining keys prevented from being depressed, while the first key is in the active position.
