<p>PURPOSE:To obtain the protective case of a cassette tape excellent in use easiness, by mounting a box-shaped main body receiving the exposed part of a magnetic tape and a movable member exposing the upper end of the cassette tape even in such a state that a stopper piece is engaged with a hub hole. CONSTITUTION:The lower end of a cassete tape 50 is inserted in an opening 1a in a slightly oblique direction so as to avoid a stopper piece 5 and the exposed part 52 of a magnetic tape is received in a main body. The stopper piece 5 shaken and retracted to the outside is matched with a hub hole 53 along with a movable plate material 11 and engaged with the engaging piece 54 inserted in the hub hole 53 by the elastic recovery force of a notch 12 coupled with the guidance of an oblique surface 6. As a result, the cassette tape 50 is received in a protective case. Further, the thumb is pressed to an antiskid part 18 and four fingers are pressed to the surface of the cassette tape 50 on the side opposite to said antiskid part and, when the thumb is pushed out from this state and four fingers are retracted the stopper piece 5 and the movable plate material 11 are shaken and retracted to the outside and the cassette tape 50 is pulled out from the main body 1 to be separated from the protective case.</p> |
