Abstract

La presente invención se refiere a estructura de muelle laminar para cassette de cinta magnética, en particular video cassette, que comprende una lámina elástica con conformación alargada acoplable, por su porción media, a la tapa de una cassette, y que actúa, en la proximidad de sus extremos libres, sobre el perno central de las bobinas de soporte de la cinta magnética, caracterizada porque presenta, por el lado vuelto hacia dichas bobinas una disposición general cóncava con por lo menos una línea de plegado en la porción comprendida entre el extremo libre y la zona de acoplamiento a la tapa, siendo dicha lámina de plegado, con dicha lámina elástica insertada en dicha cassette, apta para acoplarse por contacto con dicha tapa para definir por lo menos un punto de articulación para la oscilación elástica de dicha lámina, presentando dicho punto de articulación de dicho perno de la bobina una distancia inferior a la distancia entre dicho perno y dicho punto de acoplamiento a la tapa.
