This hanger case 1 can slide horizontally along a hanger rail 9. In addition, a pair of upper and lower ribs 11 and 12 are provided on the lower surface of the top plate 3 and the upper surface of the bottom plate 4 in the left-right direction (hanger rail 9
They are integrally formed so that they are offset from each other in the longitudinal direction.

On the other hand, as is conventionally known, the VTR tape cassette 14 is made of synthetic resin and has a front opening 15.
A magnetic tape 18 is wound around a pair of reels 19 and 20 and stored in a cassette casing 17 having an opening 16 at the bottom. The opening 15 is covered and the magnetic tape 18 is guided by a pair of tape guides 22 and 23 attached to both sides of the front opening 15 inside the cassette housing 17, so that the magnetic tape 18 is guided along both openings 15 and 16 along the inside of the front lid 21. It is made by spanning across it. Therefore, this tape cassette 1
The bottom opening 16 of No. 4 is always open. In addition,
At the bottom of the cassette housing 17, the seventh
In the figure, a pair of cassette positioning holes 24 and 25 are provided at both upper and lower positions. When the tape cassette 14 is installed horizontally inside the VTR,
Insert two of the plurality of cassette positioning pins provided inside the VTR into the pair of cassette positioning holes 2.
4, 25 to horizontally position the tape cassette 14 in a predetermined position.

The hanger case 1 stores the tape cassette 14 on one side of the front cover 2.
It is inserted into this hanger case 1 from the first side and held vertically. At this time, a pair of guide grooves 26 and 27 provided along both upper and lower end surfaces of the vertical cassette housing 17 are connected to a pair of ribs 1.
By aligning and fitting the tape cassettes 1 and 12, the tape cassette 14 is always inserted into the hanger case 1 in a constant vertical position.

Conventionally, an elastic piece 28 having elasticity is integrally molded on one side 5 at the upper end side of the hanger case 1, and a locking part 29 consisting of a small protrusion is integrally provided on the inner surface of the elastic piece 28. Case 1
The tape cassette 14 inserted vertically into the tape cassette 14 is clicked into the cassette positioning hole 24 located above the bottom opening 16 with the locking part 29 against the elasticity of the elastic piece 28. The cassette 14 was configured to be positioned within the hanger case 1.

[Problem that the invention attempts to solve]

However, in the structure of the conventional hanger case 1 in which the locking part 29 is click-locked into the cassette positioning hole 24 located above the bottom opening 16 of the tape cassette 14 against elasticity, the hanger When the tape cassette 14 is attached to and detached from the case 1, scraped particles of the synthetic resin generated by abrasion due to the engagement and disengagement between the locking part 29 and the cassette positioning hole 24 are removed under the cassette positioning hole 24. It easily enters the bottom opening 16 located on the side by natural falling. The shavings that have entered the bottom opening 16 adhere to the magnetic tape 18 that is stretched across the bottom opening 16, causing dropouts during recording and playback of the magnetic tape 18. This could easily cause damage to the recording/playback head of the VTR. Furthermore, the positioning hole 24 of the tape cassette 14 is an important hole that serves as a reference for positioning when the tape cassette 1 is attached to a VTR.
Due to frequent attachment and detachment of tape cassette 4, the cassette positioning hole 24 is easily worn and its dimensions change easily, causing the problem that the tape cassette 1 becomes misaligned when it is attached to a VTR. .

This device was devised to solve these problems, and is designed to prevent synthetic resin shavings generated when attaching and detaching the tape cassette to the hanger case from entering the tape cassette. It is something to do.

[Means for solving problems]

The hanger case for tape cassettes of this invention is configured so that a resilient locking portion is integrally formed on the lower end of the hanger case, and this locking portion is adapted to lock against the resilience of a locking portion provided on the lower end of the tape cassette inserted vertically.

[Effect]

According to the tape cassette hanger case of this invention, the action of engagement and disengagement between the locking part and the locked part is performed at a position below the bottom opening of the tape cassette inserted vertically into the hanger case. Since this is carried out at a certain lower end position, the synthetic resin shavings generated by the above-mentioned engagement and disengagement will be removed from the bottom opening of the tape cassette, which is located above the engagement and disengagement position. This prevents accidental intrusion into the tape cassette.
Therefore, it is possible to prevent the shavings from accidentally adhering to the magnetic tape in the tape cassette.

[Embodiment] Hereinafter, an embodiment of this invention of a hanger case using a VTR tape cassette will be explained with reference to FIGS. 1 to 5. Note that the same reference numerals are given to the same structural parts as those of the conventional example shown in FIGS. 6 and 7, and the explanation thereof is omitted.

In the hanger case 1 of this invention, an elastic piece 31 having elasticity is integrally molded on the bottom plate 4, which is the lower end thereof, and a locking part 32 consisting of a small protrusion is integrally provided on the upper surface of the elastic piece 31.

When the tape cassette 14 is vertically inserted into the hanger case 1 as shown in FIGS. 1 and 2, the vertical tape cassette 14 is The locking portion 32 is inserted into the locking portion 33 of the elastic piece 31, which is a hole for inserting the lock release protrusion of the front cover 21 between the front cover 21 and the cassette housing 17 provided on the lower end surface. The tape cassette 14 is positioned in the hanger case 1 by being clicked against elasticity.

Therefore, according to the hanger case 1 of this invention, the tape cassette 1 for the hanger case 1 is
The action of engagement and disengagement between the locking part 32 and the locked part 33 due to the attachment and detachment of the tape cassette 14 that is vertically inserted into the hanger case 1
Since this is done at the lowest position, which is a position below 5, the scraped powder of the synthetic resin generated by the abrasion caused by the engagement and disengagement between the locking part 32 and the locked part 33 is directly transferred to the hanger case. 1 and the lower end of the tape cassette 14.
Therefore, the shavings accidentally enter the tape cassette 14 from the bottom surface 16 of the tape cassette 14 located above the engagement and disengagement position, and damage the magnetic tape 18 in the tape cassette 14. It is possible to prevent accidental adhesion to the surface.

In this embodiment, a horizontal rib 35 is provided on the lower end of the inner surface of the other side wall 6 of the hanger case 1.
is integrally provided, and when the tape cassette 14 is vertically inserted into the hanger case 1, the front cover 21, which is cut from the front surface of the front cover 21 of the tape cassette 14 to the bottom surface 17a of the cassette housing 17, is unlocked. In another insertion hole 35 for inserting the protrusion,
The ribs 34 are inserted horizontally.

With this configuration, the upward movement of the tape cassette 14 inserted into the hanger case 1 is restricted by the rib 34, so that the locking portion 32 is not engaged with the locked portion 33. When the tape cassette 14 is placed in the hanger case 1, the tape cassette 14 does not escape upwardly in the hanger case 1. Therefore, the locking part 32 can be relatively firmly locked in the locked part 33, and the tape cassette 14 can be held in the hanger case 1.
The tape cassette 14 can be firmly positioned, and the tape cassette 14 can be prevented from accidentally falling out from inside the hanger case 1.

Also, according to the hanger case 1 of this invention,
The locking portion 32 is located in the positioning hole 2 of the tape cassette 14.
4 and 25, the locking portion 32
The positioning holes 24, 25 are never worn out and their dimensions are never changed.

Although the embodiments of this invention have been described above, this invention is not limited to the embodiments, and various effective changes can be made based on the technical idea of this invention.

Further, this invention is not limited to hanger cases using VTR tape cassettes, but can be applied to hanger cases for various tape cassettes.

[Effect of idea]

As mentioned above, in the tape cassette hanger case of this invention, the synthetic resin shavings generated when the tape cassette is attached to and removed from the hanger case are removed from the lower end of the tape cassette, which is inserted vertically into the hanger case. Since it only occurs in
This shavings will not enter the tape cassette and be accidentally attached to the magnetic tape. Therefore, inconveniences such as dropouts and damage to the recording/reproducing head etc. do not occur during recording and reproduction of the magnetic tape, and reliability can be significantly improved.

Furthermore, as shown in the embodiment, since the part other than the cassette positioning hole on the bottom of the tape cassette can be used as the locked part, the cassette positioning hole is worn and the dimensions change unexpectedly as in the conventional case. This prevents the tape cassette from being misaligned in its mounting position relative to the VTR or the like.
