Abstract

(57) [Summary] [Purpose] To provide a cartridge case which is excellent in protection of a cartridge which is stored cheaply and which prevents damage due to dropping of the cartridge or the cartridge storage case. [Structure] The bottom side of the resin book type storage case 1 is made narrower than the size of the cartridge so that the cartridge does not drop from the case. Moreover, even if the storage case is dropped as it is, the case has a simple structure, so that the case is unlikely to be damaged, and the protection performance of the cartridge can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk capable of recording, reproducing or erasing high density and large capacity information, and more particularly to a storage case for the medium.

[0002]

2. Description of the Related Art Many of the information-recorded or recordable discs housed in a cartridge further house a cartridge in order to improve the appearance and protect the case. . The shape of a conventional cartridge case will be described below with reference to the drawings. Figure 2
FIG. 4 is an external view of a conventional cartridge case.

FIG. 2A shows a single-open type made of resin, and 21 is a cartridge case housing, which is composed of a holding portion 21b for temporarily holding a disk cartridge and a housing 21a for supporting the cartridge. Reference numeral 22 denotes a case lid. After the cartridge is stored in the lid 21, the lid is placed with the rotation support portion (hereinafter referred to as a hinge) of 23 as a fulcrum to secure the safety of the disc main body in handling and operability during transportation and storage. Has been secured.

FIG. 2B shows a bookcase type article.
This type has 24 cartridge cases to improve the operability of storing and removing cartridges.
Many have notches shown in b.

[0005]

However, in the case of the shape described in the above-mentioned conventional example, when the cartridge storage case is of the one-sided opening type made of resin, the cartridge is relatively less damaged when dropped, but the cartridge storage case Very often the hinge part of the case breaks. Also, since the bookcase type thing has the same shape as the insertion opening and the bottom, if you hold the cartridge storage case containing the cartridge, depending on the direction, only the cartridge will drop from the cartridge storage case and the cartridge will be damaged. There was an occasion.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a resin case is used to make the bottom of the cartridge storage case narrower at least inside the cartridge insertion opening. By making the cartridge narrower than the cartridge stored in the case, the elasticity of the resin is used to obtain the force for sandwiching the cartridge.

[0007]

By taking the above-mentioned means, it is possible to obtain a cartridge storage case in which the disc is unlikely to drop from the cartridge storage case and the case is less likely to be damaged even if the disc and the case are dropped together.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a perspective view of a cartridge storage case that is an embodiment of the present invention, and FIG. 2B is a perspective view of a cartridge that stores the case. Reference numeral 1 denotes a cartridge case body, which has a notch 1b for insertion and removal. Two
Reference numeral 3 designates a cartridge in which a disc which is a recording medium is inserted, and reference numeral 3 designates a shutter which can be slid and opened only when recording and reproducing information on the recording medium.

In the cartridge case 1, the T side is the case insertion port and the E side is the case bottom. Insertion slot T
The width WT on the side is 1 mm wider than the width WE on the bottom E side, and WE is
The width WC of the cartridge stored in the case is set to be 0.4 mm narrower. The height of the case was the same on both the T and E sides. Since the WE is narrower than the WC, the case expands from the portion where the size of the WC or less is inserted by inserting the cartridge, and at the same time, the force for pinching the cartridge is generated, and when the force exceeds a certain value, the case is turned upside down. It is possible to realize that the cartridge does not drop. The material of the resin is polypropylene, and the recording medium contains an antistatic agent because it is extremely dust-proof.

In order to confirm the index label when it is put in the case, the part where the index label can be seen is transparent, and the transparent sheet is easily scratched, so the inner surface of the case is processed to make a straight line or a curve such as a circle. It uses a sheet that contains line embossing with regular linear pattern protrusions. As a result, the appearance is improved, the coefficient of friction between the cartridge and the case is increased, and a structure that is less likely to slip off can be obtained. In addition to the line embossing, the same effect can be obtained by roughening the surface of the ground glass in a random manner. Further, the side surface of the case is bonded by ultrasonic welding and is strong against impact such as dropping, but the bonding method may be another method such as hot melt. The width of the case may be WE rather than the lower surface of the case, and may be several cm from the lower surface. Further, it is possible to narrow the width from the T side not only in the width but also in the thickness direction (HE <HT). Of course, both width and thickness may be used. The outer dimensions are the same on both the T side and the E side, the resin thickness is slightly different, and the auxiliary member is attached to the E side.
The same effect can be obtained by setting the above relationship. Further, the width WT on the insertion port T side and the width WE on the bottom E side are the same size, and a similar effect can be obtained by providing a portion corresponding to the width WE of the bottom of the embodiment in the intermediate portion between the insertion port and the bottom. The insertion opening is slightly larger than the width WC and the height HC of the cartridge to improve the operability of insertion, and at least one of the width and height of the portion from the insertion opening T to the bottom E is set. By slightly reducing the width WC and the height HC of the cartridge, the risk of dropping only the cartridge can be extremely reduced, and the recording medium such as the cartridge and the built-in disk, and the information recorded on the medium. It is possible to provide a very effective cartridge case in terms of protection.

[0011]

As described above, the size of the lower surface of the cartridge storage case is narrower than the size of the insertion port, and the size is narrower than the cartridge stored in the case. The cartridge can be prevented from dropping from the case, and the effect of the present invention is great.
