Abstract

L'invention concerne une cassette de bande magnétique pour appareil d'enregistrement et de reproduction magnétique. La cassette comprend une bobine de déroulement et une bobine d'enroulement 20 placées à l'intérieur d'un boîtier 4 présentant une ouverture 45 par où la bande 44 peut être extraite pour l'enregistrement ou la reproduction de signaux. Un élément 24 monté pivotant à l'intérieur du boîtier comporte un élément 26 de guidage de bande et un levier de freinage 25 empêchant la rotation de la bobine lorsque la cassette n'est pas utilisée. Une ressort hélicoïdal 40 pousse l'élément pivotant 24 de manière à faire venir le levier de freinage en prise avec des dents 22 formées sur un flasque 21 de la bobine 20, et un moyen 31, 32 permet de surmonter l'action du ressort et de libérer le levier de freinage pour l'utilisation de la cassette. L'invention s'applique notamment aux cassettes pour magnétoscopes. L'utilisation d'un ressort hélicoïdal permet une fabrication en série plus facile qu'au moyen des ressorts à bras latéraux de la technique antérieure.
