ド等（図示せず）の保護も可能である。Now, the pin 27a fixed to the outer frame 27 is engaged with the guide hole 50a provided in the stopper lever 50, and in the state shown in FIG. 1, the outer frame 27 is a spring (not shown) and is indicated by an arrow. Since the pin 27a is biased in the direction opposite to F, the pin 27a has a guide hole 50a.
It is locked and held at the end of. At this time, the inner frame 28 is biased and held downward by the inner frame pressing spring 35, but even when the inner frame 28 is moved in the direction of the outer frame 27 against the spring force, the inner frame 28
The sheet metal 28a fixed to the plate moves only to the position where it is locked by the stopper pin 51 provided on the stopper lever 50,
The space between the outer frame 27 and the outer frame 27 is secured so that the cassette 1 can be attached and detached sufficiently. Therefore, it is possible to prevent the situation where the cassette 1 cannot be inserted, and further, the space between the inner frame 28 and the chassis 29 does not increase, and there is no gap between the inner frame 28 and the exterior 60, so that the space between the inner frame 28 and the chassis 29 is not formed. It is possible to prevent the insertion of foreign matter into the magnetic head and protect the magnetic head or the like (not shown).

れ、記録または再生が可能となる。Then, the outer frame 27 is a shaft 40 whose shaft center is fixed to the chassis 29.
Rotate around, but the stopper lever 50 is
Since it rotates around another shaft 52 whose shaft center is fixed to the
The locus of 28a and the locus of the stopper pin 51 are different. Therefore, the restriction of the movement of the inner frame 28 toward the outer frame 27 by the stopper pin 51 is released, and the state can be moved to the state shown in FIG. 2. The cassette 1 is mounted on the chassis 29 and recording or reproducing is possible. Becomes
また、ストッパーレバー50と外枠27のピン27aの係合を
