Description

[Detailed Description of the Invention] The present invention relates to a case for storing cassette tapes.

As shown in FIG. 1, the cassette tape C has a window 24 opened in the front surface 27 to allow a magnetic head or the like from the outside to come into contact with the built-in magnetic tape 21. Generally, the magnetic tape 21 is housed in a case to prevent the magnetic tape 21 from entering the cassette or damaging the magnetic tape 21 exposed through the window 24.

The present invention relates to the improvement of a protective case for storing such cassette tapes when not in use.According to the present invention, the cassette tapes can be well protected and the case has excellent design and functionality. A cassette case is provided.

The present invention will be explained in detail below based on embodiments of the drawings.

Fig. 2 is a perspective view of the cassette case of the present invention, showing the state when the cassette tape is taken out, and Fig. 3 is a perspective view showing the state of storing the cassette tape in the cassette case of the present invention. It is.

An upper plate 1 and a lower plate 2 are installed opposite to each other on the upper and lower edges of the rear plate 3, and an upper support plate 4 and a lower support plate are provided on the edges of the upper plate 1 and the lower plate 2 that are paired with the rear plate 3 continuous edge. 5 is connected to the rear plate 3.

These upper plate 1 and lower plate 2, rear plate 3, and upper and lower support plates 4 and 5 are parallel to each other, and each outer surface of the entire case (upper surface, lower surface, front surface, and rear surface) is flat with no steps. have.

The cassette C is slid from the side into the space surrounded by the upper and lower plates 1.2, the rear plate 3, and the upper and lower support plates 4.5, and this space accommodates and holds the cassette C well. formed to the dimensions.

That is, the distance q between the upper plate 1 and the lower plate 2 is slightly longer than the vertical length b of the cassette C, the length p in the unloading direction of the cassette C is slightly longer than the horizontal length a of the cassette C, and the rear plate 3 The distance S between and the lower support plate 5 is slightly larger than the thickness d of the portion of the cassette c where the convex portions 25 and 26 are present, and the distance r between the rear plate 3 and the upper support plate 4 is equal to the distance S described above. Alternatively, the thickness C is set to be slightly larger than the thickness C of the flat portion of the cassette C.

However, when the distance r corresponds to the thickness C and r==s, the thickness of the rear plate 3 and the upper support plate 4 should be adjusted to maintain the flatness of the front and rear surfaces of the case and to make them parallel surfaces. Distant relatives by making it evenly thick.

M6 is attached to the upper edge of the lower support plate 5 by a hinge 14.

This lid 6 connects and covers between the upper support plate 5 and the lower support plate 6, and has an inner surface that fits into the reel shaft holes 22 and 23 of the cassette C to fix the cassette C and rotate the reel. a pair of reel shaft hole insertion protrusions 12 that prevent
13 protrudes, and a locking piece 7, which is thinner than the lid 6, is connected to the upper edge of the lid 6 so that it is flush with the front surface (with a step on the inside surface). .

This locking piece 7 is provided with an engaging protrusion 9 on its inner surface.
Moreover, its upper edge reaches the upper surface of the upper plate 1.

On the other hand, the upper support plate 4 is formed with an engaging recess 8 into which the locking piece 7 is fitted, and the locking recess 8 is further provided with the engaging protrusion 9.
An engagement hole 10 into which is fitted is provided.

Further, on the upper surface of the upper plate 1, there is a finger hole 11 that communicates with the locking recess 8.
is formed.

As shown in FIG. 3, when the lid 6 is closed, the lid 6 and the locking piece 7 fit into the space between the upper and lower support plates 4.5 and into the locking recess 8, and the front surface of the case is flat with no steps. It is one.

Note that notches 15.15 are formed on both sides of the rear plate 3, and the length of the lid 6 in the cassette extraction direction is shorter than the length p of the entire case in the cassette extraction direction (if the cassette is removed from the case). Both sides of C are exposed, and when removing the cassette from the case, it is possible to grasp and pull out the exposed portions.

Furthermore, if the notches 15.15, the corners of the upper and lower support plates 4.5, and the M6 are formed so that the front and rear shapes are the same when the lid 6 is closed, an excellent design can be obtained.

To store the cassette C in the case constructed in this way, first insert the cassette C from the side of the case with M6 released (this state is shown in Figure 2), and place it in the predetermined position in the center. Place cassette C.

Thereafter, M6 is rotated about the hinge 14 to insert the protrusion 12.13 into the reel shaft 22.23 of the cassette C, and the locking piece 7 is fitted into the locking recess 8 and the engaging protrusion 9 is inserted. The lid 6 is fixed by fitting into the engaging hole 10 (this state is shown in FIG. 3).

This means that the cassette C is installed in the case.

When taking out the cassette C from the case, by pushing the upper edge of the locking piece 7 using the finger hole 11, the engagement protrusion 9 and the engagement hole 10 are disengaged, and the lid 6 is opened.

As a result, the cassette C becomes free and can be easily removed by sliding it sideways.

In addition, in this embodiment, 6 is attached to the lower support plate 5, a locking recess and an engagement hole 10 are provided in the upper support plate 4, and a finger hook hole 11 is provided. A configuration may also be adopted in which a lid is attached to the lower edge of the plate, a locking recess and an engagement hole are provided in the lower support plate, and a finger hook hole is provided in the lower plate.

The present invention is a cassette case as described above, which can store cassette tapes in a compact manner.

Moreover, since the opening 24 of the cassette tape is completely sealed by the lower plate 2, there is no risk that the magnetic tape exposed from the opening 24 will be damaged or that dust will adhere to it. This prevents dust from entering the cassette, and furthermore, the capstan insertion hole and the like can be sealed by the rear plate 3 and the lower support plate 5, making it possible to achieve extremely good dustproofing inside the case.

In addition, by providing the reel shaft hole insertion protrusions 12 and 13 on the lid 6, the cassette tape can be securely fixed to the case, and it also prevents the reel from rotating, which prevents the tape from sagging, which can cause malfunctions during use. There's nothing to do.

Furthermore, since there are no steps on the surface of the case, it requires minimal storage space and can be stacked, making it extremely easy to store.

In addition, the operation for taking out the cassette tape requires only the attachment and detachment of the locking piece 7 following the lid 6 and the sliding of the cassette tape, which has great practical effects such as easy handling.
