Claims

[Claims for Utility Model Registration] Consisting of a pair of tape reels wound with magnetic recording tape and a cassette housing housing the pair of tape reels, the magnetic tape cassette is loaded into a tape deck at the bottom of the cassette housing. In a magnetic tape cassette provided with a lock release hole into which a lock release member on the tape deck side enters when the tape deck is opened, the pair of tape reels are provided with a locking portion consisting of a large number of recesses on the outer periphery of the flange, and the cassette is The housing has a brake member made of a single piece of resilient thin plate-like elastic material, which has a locking pawl that engages and disengages with the locking portion at one end, and the brake member has a locking pawl that engages with and disengages from the locking portion. , the lock is movable between an engagement position where it engages with the locking part and a disengagement position where it disengages from the locking part, and so as to come into contact with the lock release member that enters through the lock release hole. When the locking claw is disposed so as to cover at least a portion of the unlocking hole, and is partially pushed up by the unlocking member and curved upward, the locking pawl is released from the unlocking member and restored to the detached position. A magnetic tape cassette, wherein the locking pawl is mounted within the cassette housing so that the locking pawl is in the engaging position.
