Description

[Detailed Description of the Invention] [Industrial Application Field] The Phillips type tape cartridge has protrusions called ears near the front ends of the left and right outer surfaces.

The present invention relates to a storage box for tape cartridges with ears of this kind.

[Conventional technology]

FIG. 5 shows a Phillips-type tape cartridge and a conventionally known storage box in which the tape cartridge is individually housed (for example, Japanese Utility Model Application No. 57-184572).

All such storage boxes are made of plastic.
and a transparent lid 2. The body 1 has a front side wall 4 and left and right side walls 5 erected from three sides of a rectangular bottom wall 3 long from side to side, and a pair of locking claws 6 are provided protruding from the left and right sides of the center part on the inner surface of the bottom wall 3. A pivot 7 is provided on each inner surface of a portion 5b of the left and right side walls 5 that extends rearward from the bottom wall 3.
are protruding from each other so as to face each other inwardly.

The lid 2 is integrally formed with a pocket 10 on the rear inner surface of a rectangular upper wall 8 elongated from side to side, into which a tape cartridge 9 can be inserted and removed from the front side. This pocket 10 is open only on the front side, and its left and right side walls 11 are fitted between the rear extending portions 5b of the left and right side walls 5 of the body 1, and the pivot shafts 7 are provided on the left and right side walls 11 of the pocket 10, respectively. The lid 2 is fitted into the shaft hole 12 , and the lid 2 is pivotally connected to the rear part of the body 1 so as to be rotatable about the pivot 7 .

When the tape cartridge 9 is inserted into the pocket 10 of the lid 2 from the front side and the lid 2 is closed on the upper surface of the opening of the body 1, the locking claws 6 lock each hub 13 in the tape cartridge 9 to prevent rotation. engaged in a manner.

However, in the typical Phillips tape cartridge 9, there are ears 1 near the front ends of the left and right outer surfaces 14.
When the tape cartridge 9 is inserted into the pocket 10 from the front side of the opening, the ears 15 come into contact with the inner surfaces of the left and right side walls 11 of the pocket. Positional deviation in the direction is controlled by contact. That is, although the inner surfaces of the conventional left and right side walls 11 are slightly tapered for forming as shown in FIG. 6, they are basically finished as uniform flat surfaces in the front and back direction. Ta.

[The problem that the idea aims to solve]

In this conventional configuration, since only the left and right ears 15 of the tape cartridge 9 locally contact the left and right side walls 11 of the pocket 10, cracks are likely to occur in the side walls 11 when subjected to an external impact. especially,
A shaft hole 1 is provided near the left and right side walls 11 where the ears 5 contact.
2 is provided so as to pass through the inside and outside, and since the front end edge 11d of the front portion 11b is in a free state as an opening edge, the front side including the area around the shaft hole 12 is more likely to be damaged. Furthermore, during molding, the gate position is often set at the center of the left and right sides of the rear wall 16 of the pocket 10, but in such a case, a weld will occur at a location closer to the pocket outlet than the shaft hole 12 of the left and right side walls 11, and the corresponding location will be Since the strength of the steel is already weak, this also makes it easy for cracks to occur at the location.

However, when the tape cartridge 9 is inserted into the pocket 10 and is attached, the inner inner end portions 11a of the left and right side walls 11 of the pocket 10 touch the ears 15 on the left and right outer surfaces 14 of the tape cartridge 9.
However, since the inner inner end 11a has three sides connected to the upper and lower walls 8, 17 and the rear wall 16 of the pocket 10, the free front edge 11d, which is inherently stronger against impact loads than the front portion 11b on the pocket exit side.

Therefore, an object of the present invention is to provide a storage box having the above-mentioned basic structure having a pocket 10 at the rear of the inner surface of the lid 2, so that the tape cartridge can be stored at the inner inner end portion 11a, which is strong against impact loads, on the inner surfaces of the left and right side walls 11 of the pocket 10. The left and right outer surfaces 14 of 9 are received in a pre-contact state, thereby preventing the conventional cracks and defects from occurring in the left and right side walls 11.

[Means to solve the problem]

The present invention is based on the body 1 described above with reference to Figure 5.
In the basic storage box having a lid 2, the left and right side walls 11 of the pocket 10 have an inner inner end 11a facing a front end 14a forward of the ears 15 of the left and right outer surfaces 14 of the tape cartridge 9; ear 1
5, and a front part 11b facing the inner back end 1 so that the inner face of the inner back end 11a protrudes more inwardly of the pocket than the inner face of the front part 11b.
1a is set to be larger than the wall thickness of the front part 11b, and before the front part 11b comes into contact with the ear 15 of the tape cartridge 9, the inner rear end part 11a touches the tape cartridge 9. It is required that the front end 14a be contacted first and that the movement of the tape cartridge 9 in the left-right direction within the pocket 10 be restricted by contact with the inner inner end 11a.

[Effect]

The lid 2 rotates around the pivot 7 relative to the body 1 to open and close the opening top surface of the body 1. After rotating the lid 2 upward and inserting the front end of the tape cartridge 9 into the pocket 0, the tape cartridge 9 can be stored individually by closing the lid 2 on the body 1 side.

The pocket 10 on the lid 2 side is integrally formed at the rear of the inner surface of the upper wall 8 so that only the front side is open. This means that the pocket 10 is formed into a square frame shape having an upper wall 8, a lower wall 17, a rear wall 16, and left and right side walls 11,11.

The left and right side walls 11 of the pocket 10 have inner inner end portions 11a.
The wall thickness of the front portion 11b is set larger than that of the front portion 11b,
The inner surface of the inner innermost end portion 11a projects further inward into the pocket than the inner surface of the portion 11b. Therefore, in the stored state in which the front end of the tape cartridge 9 is inserted into the pocket 10, the inner inner end 11a touches the front end 14a of the tape cartridge 9 forward of the ears 15 on the left and right outer surfaces 14. The tape cartridge 9 is received and supported, and the movement of the tape cartridge 9 in the left and right direction is abutted and restricted at the inner inner end portion 11a.

[Effect of idea]

According to the present invention, the inner inner end portions 11a of the left and right side walls 11 of the pocket 10, which is open only at the front, are connected to the upper wall 8, the lower wall 17, and the rear wall 16 on three sides, and are originally smaller than the front portion 11b. In order to provide strength, the wall thickness of the inner inner end portion 11a is made larger than that of the front portion 11b. Therefore, even if the shaft hole 12 is formed in the inner inner end 11a, the strength of the inner inner end 11a can be sufficiently ensured. As a result, the axial length and diameter of the shaft hole 12 can be increased, and accordingly, the pivot 7 can also be set larger, thereby increasing the strength of the pivot 7 itself and improving its rotational performance. Become something.

Left and right side walls 1 with increased wall thickness to ensure strength
The inner surface of the inner inner end portion 11a of the pocket member 1 is shaped to protrude inward from the inner surface of the front portion 11b. Therefore, as in the conventional case, the tape cartridge 9
The lugs 15 of the left and right outer surfaces 14 of the pockets do not locally contact the front portions 11b of the left and right side walls 11 of the pocket, and the front end portions 14a of the tape cartridge 9 which are in front of the lugs 15 are held at the inner inner end portions 11a. It is ensured that it is received and supported in a state where it hits first, and it is possible to effectively prevent cracks from being caused by a falling impact on the left and right side walls 11, including the inner inner end portion 11a.

[First Embodiment] Fig. 1 shows the first embodiment of the present invention, and the basic structure of the storage box of the present invention is as already described. have

That is, when the front end of the tape cartridge 9 is inserted into the pocket 10 from the front side of the opening, the left and right side walls 11 of the pocket 10 are inserted.
The inner surface is the left and right side surfaces 14 of the tape cartridge 9.

The thickness of the left and right side walls 11 was set so that T≧t. The shaft hole 12 is provided in the thick inner inner end portion 11a.

In such a case, rotate the lid 2 upward with respect to the body 1, insert the front end of the tape cartridge 9 into the pocket 10 on the lid 2 side through the front opening of the pocket 10, and then insert the lid 2 into the body 1. When the tape cartridge 9 is closed and stored, the front side of the tape cartridge 9 is in the pocket 10.
At the rear wall 16, the rear surface is received by the front wall 4 of the body 1, and movement in the front and back direction is restricted by abutment, and the front ends 14a of the left and right outer surfaces 14 of the tape cartridge 9 are inserted into the pocket 10. It first contacts the inner inner end portions 11a of the left and right side walls 11, and its movement in the left and right direction is restricted by contact.

Therefore, the ears 15 of the tape cartridge 9 do not locally contact the inner surfaces of the front portions 11b of the left and right side walls 11 of the pocket 10, as in the conventional case. On the other hand, the inner inner end portion 11a that receives the front end portion 14a of the tape cartridge 9 is thick, and the rear end and upper and lower ends thereof are the rear wall 16 and the upper and lower walls 8, 17.
Since they are each integrally connected to each other, they can sufficiently withstand even concentrated impact loads.

Incidentally, in the illustrated example, the front portions 11 of the left and right side walls 11
The inner surface of b is also formed into an inclined surface that spreads forward,
The tape cartridge can be easily inserted into the pocket 10 from the front.
