SNAP-OPEN MAGNETIC TAPE CARTRIDGE

摘要

An automatically openable tape cartridge having an integrally formed snap latch. One end of the tape within the cartridge is secured to the free end of a closable lid. Upon displacing a longitudinal wall of the cartridge adjacent the free end, camming action causes the lid to snap open pulling the tape out. Mating cam surfaces on the displaced longitudinal wall and the free end of the lid forces the lid open. On the end walls of the cartridge are two inwardly opening grooves or latch-receiving means. These receive latching scallops on the ends of the lid. The scallops ride over the cartridge end walls. The cartridge contains a spool having axially movable flanges for facilitating automatic handling of the cartridge and the contained magnetic tape.
