Abstract

La présente invention concerne une cassette pour bande magnétique dans laquelle un ressort de verrouillage du volet ne se désengagera pas d'une moitié inférieure et le verrou du volet est maintenu dans une position appropriée lorsque la cassette pour bande magnétique est en cours d'assemblage. Dans la cassette pour bande magnétique, un ressort de verrouillage du volet comporte une partie en enroulement devant être attachée sur une broche de fixation réalisée sur la moitié inférieure et une extrémité libre venant au contact du verrou du volet. Une nervure de maintien à ressort permettant de retenir la partie en enroulement est formée dans un espace entre la broche de fixation et la paroi latérale de la moitié inférieure face à la broche de fixation. Dans ce cas, une hauteur de la partie en enroulement est plus grande qu'un espace qui se forme lorsque les moitiés supérieures et inférieures sont assemblées. Selon une autre réalisation un ressort de verrouillage du volet peut comporter une partie en enroulement fixée à la moitié inférieure, et des éléments de guidage peuvent être disposés respectivement dans les moitiés inférieures et supérieures et comporter des rainures de guidage permettant de guider le ressort de verrouillage du volet jusqu'à une position d'application d'une force sur le verrou du volet. Dans ce cas, les éléments de guidage sont situés en différentes positions sur un axe de distribution partant du ressort de verrouillage du volet, et les éléments de guidages sont superposés si on les considère depuis l'axe de distribution lorsqu'on fait l'assemblage de la moitié supérieure avec la moitié inférieure. Selon une autre réalisation, le couvercle peut comporter des pièces qui dépassent et qui sont situées à ses extrémités opposées, lesquelles pièces sont montées de façon lâche dans les rainures formées dans la moitié inférieure. En outre, une nervure d'arrêt peut être réalisée sur la moitié supérieure. Dans ce cas, la nervure d'arrêt retient dans la rainure les pièces qui dépassent dans des positions récupérables de ces rainures lorsque la moitié supérieure est assemblée avec la moitié inférieure et qu'elle est serrée avec des vis.
