Abstract
Mécanisme d'actionnement automatique de touches à accès aléatoire. Il comprend un levier 12 à rappel élastique manoeuvré par une came 20. Ce levier peut entraîner la touche 1 concernée par l'intermédiaire d'un cliquet 17 enclenché par un électro-aimant 18 à excitation momentanée, autorisant le déverrouillage éventuel de la touche avant la fin du cycle. Les pentes différentes de la came autorisent à la fois une manoeuvre rapide de la touche et le réarmage avec un moteur à faible puissance. L'invention peut être utilisée pour l'automatisation ou la télécommande d'un lecteur de bande.
