Title (EN) SPRING-LOADED TAPE SPOOL FOR BELT-DRIVEN CARTRIDGE
(FR) BOBINE DE BANDE CHARGEE PAR RESSORT POUR CARTOUCHE ACTIONNEE PAR COURROIE
Abstract:
(EN) A tape spool (26) for use in a magnetic tape cartridge includes structure for maintaining the spool at a predetermined height relative to the cartridge base (14). The tape spool includes a hub (62) having a central aperture (28) for mounting on a pin (50) extending from the base, an upper surface, a lower bearing surface (67) and a circumferential tape supporting rim (65). A disc (64) is attached to the hub and includes a spring (52) in contact with an upper surface of the hub, and a central bore (70) for mounting on the pin (50). A retaining member (54) is fitted on the pin (50). The disc (64) is urged by the spring (52) against the retaining member and simultaneously urges the hub downwardly such that the hub is positioned at a constant distance from the base.
(FR) Bobine de bande (26) utilisée dans une cartouche de bande magnétique et comprenant un agencement servant à maintenir la bobine à une hauteur prédéterminée par rapport à la base de la cartouche (14). La bobine de bande comporte un noyau de bobinage (62) pourvu d'un orifice central (28) servant à monter la bobine sur une cheville (50) s'étendant à partir de la base, une surface supérieure, une surface de support inférieure (67) et un rebord (65) circonférentiel de support de bande. Un disque (64) est fixé au noyau et comprend un ressort (52) qui est en contact avec la surface supérieure du noyau, et une cavité centrale (70) servant à monter le disque sur la cheville (50). Le disque (64) est sollicité par le ressort (52) contre l'élément de retenue et pousse en même temps le noyau vers le bas, de sorte que celui-ci demeure dans une position telle qu'une distance constante par rapport à la base est maintenue.
