Abstract (en)

[origin: WO9965028A2] The magnetic tape cassette comprises a lid for covering magnetic tape in a freely opening and closing manner, a lid lock for locking the lid in its closed state, and a lid spring (71) not only for energizing the lid lock in its locking direction but also for energizing the lid in its closing direction. The lid spring (71) is structured such that a coil portion (71c) thereof is mounted on a support shaft pin (61a) of the side plate (55a) of an outer lid (51) in a loose fit manner, one leg portion (71a) thereof is secured to a projection portion (65) provided on the side plate (55a), and the other leg portion (71b) thereof is secured to a projection (6) provided on the side surface of an upper half (2) and can be engaged with the lid lock from the upper half (2) side to thereby energize the lid lock in the locking direction of the lid. On the upper half (2), there is provided position restrict means (5) which can be contacted with the coil portion (71c) of the lid spring (71) to thereby restrict the position of the coil portion (71c). Accordingly, it is possible to provide a magnetic tape cassette which can prevent the shaving of a support shaft pin caused by mutual contact between the support shaft pin and the coil portion of a lid spring.
