上支障となる欠点があった。Further, as disclosed in Japanese Patent Laid-Open No. 6-103725, a hub brake interlocking with a rotating lid is provided, and it is also known that the lid locks the hub brake. Since it is necessary to form a gap with the lid, locking becomes uncertain, and it is difficult to apply in a form where the lower flange of the tape reel has an engaging portion like a normal video cassette. As in Kaihei 6-89528, a reel brake structure that withstands a drop impact by independently biasing a pair of reel brake members with springs has been attempted, but in this form, unless the spring force is increased. There is a drawback that there is no locking effect and the release force of the brake increases when the spring force is increased, which is an obstacle to handling.

としたものである。However, when a strong impact such as a drop impact is applied to the tape cassette, in the conventional brake mechanism, the brake member is simply urged by the elastic force toward the tape reel. However, if a force larger than the elastic force is applied, the brake member will move, the brake mechanism will come off, the tape reel will rotate, and the tape will loosen. In particular, recently, as the recording / reproducing apparatus has been downsized, if the tape cassette as described above is directly attached to the recording / reproducing apparatus, the tape may not hit the rotating head of the recording / reproducing apparatus because the tape position is not normal. The tape may be bent, scratched or cut. Also, there is a problem that the tape is not normally pulled out by the tape pull-out member and the tape is entangled in the recording / reproducing device, so that the tape cannot be run, or in the worst case, the tape cassette cannot be ejected from the recording / reproducing device. was there. The present invention is intended to easily eliminate various drawbacks of the related art. A reel brake mechanism for stopping rotation of a pair of tape reels rotatably housed in a case of a tape cassette when not in use has a strong drop impact. The brake is not disengaged even if an impact is applied, and the elastic biasing force of the torsion coil spring that presses the lock portion downward is stabilized to ensure the lock and the end of the torsion coil spring is not disengaged by the impact. The lock state is maintained and the lock member is prevented from coming off, so that the lock member does not come off from the brake member even when it receives a strong impact such as a drop impact, and the assembly is easy to prevent the tape from loosening. The purpose is to provide a safe tape cassette.
