Abstract

Un dispositif d'education pour la reproduction d'information visible dessinee sur la surface frontale d'une feuille magnetique (2) et d'une information audible en relation avec l'information visible enregistree sur la surface arriere de la feuille magnetique (2), par l'intermediaire d'une tete (5) sur le plateau d'un tourne-disque (4); la feuille magnetique (2) etant inseree dans la direction de la fleche et ensuite positionnee dans le dispositif. Un rouleau (8) est relie de maniere pivotante a la partie inferieure d'un tourillon (3) pour le positionnement de la feuille magnetique (2), afin que ce tourillon (3) soit pousse totalement vers le haut par un ressort (9). Le dessous du plateau (4) presente des surfaces hautes et basses de came (6a') et (6a'') concentriques. Lorsque ce plateau (4) est arrete le rouleau (8) entre en contact avec la surface de came (6a') pour relacher le tourillon (3) afin de pouvoir facilement inserer la feuille magnetique (2). Lorsque le plateau (4) se met a tourner, le rouleau (8) est separe de la surface de came (6a') ce qui force le tourillon (3) a se mouvoir vers le haut afin de positionner avec exactitude la feuille magnetique sur la tete conique (3a) du tourillon (3). Des pignons fous (16), (17), sont interposes entre un moteur (13), un volant (14), et le plateau (4) pour egaliser la rotation du plateau (4) a vitesse constante,
