2. Description of the Related Art Conventionally, as a storage case for a tape cassette, an assembling box-type integrated case is mainly used, but there is a problem in dustproofness due to the provision of an opening for taking in and out the tape cassette. .

A conventional tape cassette storage case will be described with reference to the drawings. FIG. 13 is a perspective view of a conventional tape cassette 1 and a storage case 5, and FIG. 14 shows a state where the tape cassette 1 is stored in the storage case 5. In the figure,
When the tape cassette 1 is stored in the storage case 5, the guard panel 2 side of the tape cassette 1 is located on the rear side of the storage case 5, that is, the tape label 1 is stored such that the rear label attaching area 3 of the tape cassette 1 can be seen from the outside. Insert it into case 5.

[0004]

However, the storage case 5
Since the opening 6 for taking in and out the tape cassette 1 is always open, there is a disadvantage that a part of the tape cassette 1 is exposed and dust or the like easily enters from outside. These dusts cause problems such as a disturbed screen when the tape is reproduced. Further, since the storage case 5 is of an assembling type box type, the gap between the tape cassette body 1 and the storage case 5 becomes small due to variation in adhesion and welding during assembly, and the insertability of the tape cassette 1 into the storage case 5 is improved. There is a possibility that the tape cassette 1 once inserted may fall from the storage case 5 when the storage case 5 is lifted because the clearance is large or the storage case 5 is large. Further, since the storage case 5 is generally opaque in color, there is a disadvantage that the label attaching area 4 at the center of the upper surface of the main body of the tape cassette 1 cannot be seen while being stored in the storage case 5.
