ABSTRACT:
The tape cartridge improved boss door provides a sleeve between the lower boss for the torsion spring to rotate around to decrease the stress applied to the top coil of the torsion spring. An improved catch contacts the top leg of the torsion spring at a point distant from the torsion spring coils to further reduce the force applied to the torsion spring and the frictional drag as the torsion spring rotates around the sleeve, thus decreasing the failure rate of the tape cartridge due to premature failure of the torsion spring.
