Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium cartridge. Specifically, it accommodates a recording medium such as an optical disk,
The present invention relates to a recording medium cartridge that can be taken out freely.

[0002]

2. Description of the Related Art As a recording medium utilizing optics, there are a read-only compact disc (CD), a write-once optical disc (WD), a magneto-optical disc (MO) and the like.
Among these optical recording media, CDs are sold by housing the disc itself in a case, and the disc itself is put in and taken out from a reproducing apparatus. However, other recording media (disks) such as WO and MO type are generally structured such that the disk is housed in a cartridge and inserted into and taken out from the recording / reproducing apparatus.
It is not designed to accept WO or MO disks that are not housed in a cartridge.

For this reason, this type of cartridge has a structure in which the disk cannot be easily taken out after the disk is once housed, that is, a structure in which the disk is assembled by screwing, welding or the like.

[0004]

In the case of testing discs, there is a problem that the work of assembling all the discs in the cartridge as described above and taking them out again after the test becomes extremely inefficient work. is there. Further, even in general use, there is a problem that the disk is actually unusable even if the cartridge is damaged and the inner disk is intact.

DISCLOSURE OF THE INVENTION The inventors of the present invention have conducted a study on a cartridge which can easily accommodate and take out a recording medium such as an optical disk, and as a result, have made a cartridge having a case and a cover having a special structure. Thus, the object was achieved and the present invention was completed. The gist of the present invention is a cartridge that accommodates a disk-shaped recording medium having a held portion that is held by a spindle device in the center, and has a substantially rectangular outer shape when viewed in plan, with the upper part open. A case made of synthetic resin having an opening at a position corresponding to a held portion of a recording medium below and an operating position of a recording / reproducing head, and a cover fitted in a sliding manner for covering the upper side of the case. And a cartridge for a recording medium.

The cartridge of the present invention will be further described below with reference to the drawings. FIG. 1 is a perspective view of the cartridge of the present invention. In the figure, 1 is a cartridge, 2 is a case, 3 is an opening for a held portion, 4 is an opening for a head, 5 is a support wall, 6
Is a peripheral wall, 7 is a bottom plate, 8 is a cover, and 9 is a fitting piece. The cartridge 1 of the present invention comprises a case 2 for receiving a disk-shaped recording medium and a cover for covering the case 2 from above.

The case 2 is usually formed by injection molding using a thermoplastic synthetic resin, and has a substantially rectangular outer shape when seen in a plan view. This size, a fitting recess for fixing to a recording / reproducing device provided around it, may be provided according to the standard. At least a portion for receiving the disc-shaped disc is open above the case 2, and a peripheral wall 6 is provided around the case 2 to maintain a predetermined height.

The lower plate 7 of the case 2 is provided with an opening 3 at a position corresponding to a held portion held by the spindle of the recording / reproducing apparatus at the center of the disk-shaped disc to be housed, and around the opening 3. In order to prevent the recording / reproducing surface of the disk-shaped disc housed therein from contacting the lower surface plate 7, there is provided a support wall 5 made of a ridge for forming a gap between the disk-shaped disk and the lower surface plate 7. ing. Further, the lower plate 7 is formed with an opening 4 for the recording / reproducing head to access (work) the disk. The held portion opening 3 and the head opening 4 may be provided independently, but are normally provided continuously due to their positional relationship.

In order to cover the upper side of the case 2 in this manner, the cover 8 fitted in a sliding manner is used. The cover 8 is usually made of metal such as stainless steel,
It goes without saying that it may be formed of synthetic resin or the like.
Fitting pieces 9 that hold the case 2 and the cover 8 in a fitted state and in a slidable manner are provided on both sides of the cover 8 so as to sandwich the side portions of the case 2.

The structure of the fitting piece 9 is not limited to that shown in the drawings, and various structures are possible, for example, by forming a groove on the peripheral wall of the side portion of the case 2 to form the fitting piece 9 that engages with the groove. Is possible. In any case, any structure may be adopted as long as the cover 8 is slidably fitted to the case 2. In a position where the cover 8 is closed with respect to the case 2, an opening is usually provided at a position corresponding to the held portion of the disk-shaped disk to be housed, similar to the case 2. Further, similarly to the case 2, it is preferable that a support wall is provided around the opening facing the case 2. When the cover 8 is made of metal or the like, the support wall may be made of synthetic resin or the like and may be provided by being bonded by post-processing. Of course, when the cover 8 is made of synthetic resin or the like, the support wall may be integrally formed.

When a protrusion such as a support wall is formed on the inner surface of the cover 8, the protrusion is caught on the peripheral wall of the case 2 when the cover 8 is slid and opened. The height of the part corresponding to the object will be lowered. The front side portion of the cover 8 is preferably cut in an arc shape. With such a shape, the upper portion of the disc-shaped disc is completely opened without sliding the cover 8 to completely remove it from the case 2, which is convenient for taking out and storing the disc.

[0012]

According to the cartridge of the present invention, it is easy to put the recording medium in and out of the cartridge, and it is very convenient when the recording medium is applied to a test apparatus or when it is necessary to replace the recording medium cartridge. Is.
