Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a cassette storage case for storing a magnetic tape cassette, and more particularly to a magnetic tape cassette holding mechanism at the time of opening and closing.

[Conventional technology]

A storage case for a conventional magnetic tape cassette, for example, a compact cassette, is composed of two parts, a case body 11 and a case lid body 12, as shown in FIG.

The case body 11, which is one of the parts, is made of a molded product of a transparent or semitranslucent plastic material, and has a fixed bottom 11d.
A magnetic tape cassette 2 (not shown) is provided on a fixed bottom 11d composed of side walls 11a, 11b, 11c standing upright from the three sides.
Two tape slack preventing pieces that engage with the center hole of the winding frame are integrally formed, and pivoting protrusions 13 and 14 are integrally protruded on the inner surfaces of both side walls 11a and 11b.

The case lid 12, which is the other part, is made of a molded product of a transparent or semi-translucent plastic material.
A pivot hole 1 which is composed of side walls 12a, 12b, 12d and a bottom wall 12e, and on both side walls 12a, 12b is pivotally attached to the pivot attachment protrusions 13, 14.
5,16 are formed.

The case main body 11 and the lid 12 configured as described above are rotatably assembled by being axially fitted to the pivotal attachment projections 13 and 14 and the pivotal attachment holes 15 and 16 to form a storage case. The magnetic tape cassette 2 is loaded as shown in FIG.

However, when the thickness of the storage case is reduced for the purpose of space saving, the thickness of the magnetic tape cassette is defined by the standard, and therefore there is a constraint to satisfy the wall thickness of the case lid 12 within the practical use range. Therefore, the thickness cannot be easily reduced. Further, as shown in FIG. 7, when the wall thickness t of the case lid is locally thinned, a product cannot be produced due to the mold structure. Therefore, when it is possible to produce the mold structure as shown in FIG. 8, depending on the opening / closing direction, Magnetic tape cassette 2 is an arrow
When moving to C or D, there is a problem in opening and closing, or because the loading direction of the magnetic tape cassette 2 was changed as shown in FIG. 9, the tape surface of the tape window of the magnetic tape cassette 2 is touched by hand when opening and closing. There are cases.

[Problems to be solved by the device]

The present invention does not hinder opening and closing by holding the magnetic tape cassette outer peripheral projections by the projections provided on both side walls of the case lid in the magnetic tape cassette storage case.
The magnetic tape cassette storage case is characterized in that the magnetic tape surface is not touched by hand and the thickness direction is thin, which is excellent in space saving.

[Means for solving the problem]

The present invention does not hinder opening and closing by holding the magnetic tape cassette outer peripheral projections by the projections provided on both side walls of the case lid in the magnetic tape cassette storage case.
The magnetic tape cassette storage case is characterized in that it does not touch the magnetic tape surface with a hand and is excellent in space saving and has a thin thickness direction.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective development view of a storage case for storing the magnetic tape cassette of the present invention, FIG. 2 is a sectional view showing a state in which the magnetic tape cassette is stored, FIG. 3 is a view taken along arrow A, and FIG. The figure is the third
It is sectional drawing which shows the cross section BB of a figure.

The storage case 1 comprises a case body 3 and a lid body 4
Is rotatably attached to the case body 3 by axially interlocking the fulcrum holes 5 and 6 provided on both side walls 3a and 3b of the case body 3 with the protrusions 7 and 8 provided on the side wall pieces 4a and 4b of the lid 4. Be pivoted to. Side wall pieces 4a, 4b of the lid 4
When the tape opening window 2a is inserted downward along the inner surface 4c of the lid body 4, the tape opening window 2a is closed by the back surface 4d of the lid body 4, and the tape opening windows 2a are provided at the tips of the side wall pieces 4a and 4b, respectively. The protrusions 9 and 10 and the outer peripheral protrusions 2b and 2c of the magnetic tape cassette 2 are engaged with each other as shown in FIG. 4, and the magnetic tape cassette 2 is held so as not to come off the inner surface 4c of the lid 4 and opened / closed. There is no need to worry that it will hinder your work.

When the lid 4 is rotated and stored in the case body 3, the magnetic tape cassette 2 is closed together with the lid 4, and the tape slack preventing pieces 3c and 3d provided on the case body 3 and the tape winding reel are engaged. It is stored together.

Front and back protruding surfaces 2d, 2 on the tape window side of the magnetic tape cassette 2
By providing a recess 3e on the bottom surface of the case body 3 and a recess 4e on the inner surface 4c of the lid body 4 corresponding to e, the thickness of the magnetic tape cassette 2 stored in the storage case 1 can be reduced.
Further, since the protrusions 9 and 10 of the lid 4 and the outer peripheral protrusions 2b and 2c of the magnetic tape cassette 2 are engaged with each other, the magnetic tape cassette 2 can be made thin while the lid 4 is housed and the tape window is closed. Can be made into a state.

[Effect of device]

According to the present invention, a magnetic tape cassette is inserted between a protrusion protruding from both side wall pieces of a lid body pivotally supported on a side wall of a main body of a storage case and a concave portion provided inside the lid body. Since either one of the front and back protruding surfaces of the magnetic tape cassette is fitted into the concave portion and the outer peripheral projection engages with the projection, the magnetic tape cassette is held so as not to come off from the lid body. It is possible to protect the tape and prevent the magnetic tape cassette from popping out when the storage case is opened.
