In this closed state, the left and right side wall portions 12b and 12c of the upper case half body 12 and the inner side surfaces of the front wall portion 12d are respectively left and right side wall portions 11b and 11 of the lower case half body 11.
c and the outer surface of the front edge protruding portion 11d are closely overlapped with each other, whereby the cassette storage case 10 is held in a sealed state, and the internal cassette 1 is protected from the external environment.

[0012]

In such a conventional cassette storage case, when a shock is applied from the outside while the cassette 1 is stored, the slider 7 of the cassette 1 unexpectedly opens due to its strength and direction. (The cassette for DAT is equipped with a spring for biasing the slider 7 in the closing direction and a slider lock mechanism for locking the slider 7 in the closed state. The slider 7 will open if a strong impact is applied that exceeds the lock holding force of.

In particular, when the DAT cassette is shipped as a product in a cassette storage case, a great shock is applied during the transportation of the product, and the slider may be opened when the product reaches the user's hand. It could be a big problem.

The present invention has been made in view of the above points,
An object of the present invention is to provide a cassette storage case that can reliably prevent the slider of the cassette from opening when the cassette is stored.

[0015]

In order to achieve the above object, the present invention provides a cassette storage case for storing a cassette having a slider for opening and closing a hub drive shaft insertion hole and the like. It is provided with a protrusion that engages with the slider when stored and prevents the slider from opening.

[0016]

In the cassette housing case of the present invention constructed as described above, even if a strong impact is applied during transportation or the like, the slider restricts the sliding of the slider, so that the slider may be accidentally opened. Absent.
