The present invention relates to a disc cartridge, and more particularly, to a disc cartridge to facilitate mounting and dismounting of a disc to enable both use in a cartridge state and use as a single disc.

In general, an optical disk records information by using a laser beam on the surface of a disc. The optical disk converts information of a voice or an image into a digital code and shoots a weak laser beam to recognize the intensity of the reflected light and read the information. Mass storage media.

Such optical disc media include compact discs (CDs), DVDs, LDs, and the like. Recently, Blu-Ray Disc camps and AOD (Advanced Optical Disc) camps are being used as next-generation optical disc storage media standards.

The Blu-Ray Disc was developed to target High Definition Video Disc Recorders (HDVDR), and it is a blue-violet semiconductor laser that can record more data than conventional red laser beams. Next-generation optical disc storage media using light rays.

Therefore, it has a data storage capacity of 27 gigabytes corresponding to 13 hours of general movie and 2 hours of video of high definition (HD) TV quality.

These Blu-Ray Discs are attracting attention as new storage media that compensate for the shortcomings of existing DVDs.

On the other hand, the disk-type recording medium is generally inserted into a separate case for storage to protect the recording surface from external dust inflow and scratches during storage and transportation of the disk.

On the contrary, in recent years, as the recording density increases and the thickness of the protective layer becomes thinner, the cartridge for the continuous protection of the recording surface even in the process of carrying and mounting the disk for inserting the disk into the storage and reproducing apparatus of the disk-type recording medium. It may also be used in the form of an insert.

On the other hand, the storage and reproducing apparatus of the disc-shaped recording medium can generally insert only a single object of the disc according to the use, or can use both methods that can be inserted in the state of the cartridge in which the disc is combined.

For example, portable storage and playback devices require the insertion of a single disc rather than the insertion of a disc mounted in a cartridge due to space limitations.

Therefore, when a disc to be inserted and used in a cartridge is to be used in a storage and reproducing apparatus of a portable disc recording medium which can be inserted only as a single disc rather than in a cartridge state, it is necessary to separate the disc from the cartridge.

However, the existing Blu-ray disc cartridge is to be used only with the disc 2 mounted inside the cartridge, as shown in Figs.

That is, in the state where the disc 2 is accommodated inside the cartridge, when the disc 2 is to be removed by combining the lower case 1 and the upper case 3 by the screw S, the screw S is removed. You must solve all of them.                         

In addition, when the screw (S) is released as described above, there is a high possibility that various components as shown in FIG. 3 are removed.

That is, inside the cartridge, a shutter 6 for opening and closing the window W for drive access, a rotating wheel 7 for opening and closing the shutter 6, and a shutter 6 for maintaining the closed state Shutter latches (not shown), etc. are installed, and these components are not likely to be removed when the screw (S) is removed because they are not fixed inside the cartridge.

Therefore, the development of a disc cartridge that can be easily mounted and detached from the inside of the cartridge 2 and made therein become an important concern so that both the use in the cartridge state and the use of the disc 2 as a single object become an important concern. have.

SUMMARY OF THE INVENTION The present invention has been made in view of the above technical necessity and the like, and it is possible to easily detach and mount a disc from a cartridge, thereby implementing a disc cartridge that enables both the use in a cartridge state and the use as a single disc. There is a purpose.

On the other hand, in the case of the disc cartridge, the portion in contact with the recording surface is blocked from the outside in order to protect the disc recording surface. However, when storing the disc or performing recording, part of the blocking surface of the cartridge can be opened and closed because the recording surface must be exposed.

Also, in the case of the label surface, which is a surface on which data is not recorded, it is also generally to be blocked from the outside, but in order to easily distinguish the disk of the user, only a part of the label is blocked so as to prevent only the detachment of the disk.

In particular, in order to suppress the shaking of the disk in the disk cartridge during transportation and storage, and to prevent the inflow of dust or the like from the outside, a structure in which the disk is in close contact with the recording surface or the reverse surface is also used.

In other words, the present invention provides a disk cartridge for this type of disk cartridge to maintain the original function and appearance that the disk cartridge should have, and to easily detach the disk from the cartridge by a simple operation by the user. The purpose is.

In order to achieve the above object, the present invention includes a lower case having a pocket for mounting the disk and a window for drive access; Left and right upper cases spaced apart from each other on the upper surface of the lower case to exclude interference with the entry and exit of the disk to allow the disk to be seated in the lower case pocket and the disk to be removed from the pocket; Included in the slide between the left and right upper case and the separation preventing member which is located in the pocket area of the lower case when being pushed toward the center side of the lower case to prevent the removal of the disk seated in the pocket: There is provided a disc cartridge characterized in that it is configured.

(2) Slidable between the left and right upper case (3a, 3b) and the left and right upper case (3a, 3b) which are spaced apart from each other on the upper surface of the lower case (1) so as to exclude interference with the entrance and exit In addition to being installed in the pocket area of the lower case (1) when pushed toward the center side of the lower case (1) separation room provided to prevent the removal of the disk (2) seated in the pocket Comprises a member (4).

Here, the guide protrusions 41 are formed on both side surfaces of the separation preventing member 4, and the guide protrusions 41 are inserted into the inner surfaces of the left and right upper cases 3a and 3b corresponding thereto to move in a sliding manner. Guide grooves 31 are formed.

At this time, the guide protrusion 41 and the guide groove 31 may be formed in the member on the opposite side of course.

That is, guide grooves are formed on both side surfaces of the release preventing member 4, and guide protrusions are formed on the inner surfaces of the left and right upper cases 3a and 3b corresponding thereto, and the guide protrusion is inserted into the guide groove and slides. By moving it is possible to implement the sliding movement of the separation preventing member (4).

In addition, although not shown, the sliding movement structure as described above may be applied to the separation preventing member 4 and the lower case 1.

That is, guide protrusions may be formed at both ends of the lower surface of the departure preventing member 4 and guide grooves may be formed on the upper surface of the lower case 1 corresponding thereto to implement a sliding movement structure. The guide grooves may be formed at both ends of the lower surface of 4) and guide protrusions may be formed on the upper surface of the lower case 1 corresponding to the sliding groove structure.

On the other hand, the release preventing member 4 and the left and right upper case (3a, 3b) in the state in which the release preventing member 4 is pushed by sliding to the center of the lower case 1, until the user releases restraint It is to be provided with a locking means that does not naturally open.

In this case, as the locking means, as shown in FIG. 5, a fitting protrusion 51 is formed on one side of the release preventing member 4 or the left and right upper cases 3a and 3b and fitted to a portion corresponding thereto. The groove 61 may be formed so that the separation preventing member 4 may be snap-fitted by applying a force of a predetermined size or more in the sliding direction, and vice versa.

That is, the fitting protrusions 51 are formed on both side surfaces of the upper release preventing member 4 of the guide protrusion 41, and the fitting grooves 51 are fitted in the left and right upper cases 3a and 3b to correspond to the fitting protrusions 51. 61 is formed so that the release preventing member 4 is locked in the pushed state toward the center of the lower case 1 as the fitting protrusion 51 is elastically coupled to the fitting groove 61.                     

Here, the fitting protrusion 51 and the fitting groove 61 may be formed by replacing the opposite side member, the locking method as described above is also applicable to other sliding sliding structure of the above-described separation prevention member (4) Of course.

In addition, the locking means may be configured by a push button method or a slide method, which are generally widely used, so that locking and unlocking may be performed.

On the other hand, the disc cartridge of the present invention also has a shutter for opening and closing the window (W) for the drive access and a structure for opening and closing it is provided, such a shutter drive structure as described in the prior art is applied, or other known Other shutter opening and closing structures may be applied, but their structures are not directly related to the opening and closing structure for detaching the disk 2 of the disk cartridge, and thus detailed description thereof will be omitted.

The operation of the present invention configured as described above is as follows.

The lower case of the disc cartridge has a structure that is blocked from the outside except for the window W for drive access to protect the recording surface of the disc 2, and the window for drive access during recording and playback of the disc 2 ( Through W) a portion of the disc 2 is exposed.

Therefore, when inserted into the storage and playback apparatus in the state of the disc cartridge, the recording surface of the disc 2 is exposed through the window W for the drive access.

That is, when the disc cartridge is inserted into the reproducing apparatus while the disc 2 is mounted, the shutter (not shown) of the disc cartridge is opened by the operation of the reproducing apparatus, so that the drive drive drives the disc (through the window W). The recording surface of 2) can be accessed.                     

On the other hand, in the state in which the disk 2 is coupled to the cartridge, the disk 2 must be separated from the disk cartridge for use in a portable storage and reproducing apparatus for inserting only the single medium of the disk 2.

At this time, the disc cartridge of the present invention maintains the state in which the separation preventing member 4 is connected to the left and right upper case (3a, 3b) so as to be slidable, the sliding prevention member (4) by sliding the disc 2 You can pull out.

That is, in the case where the disc 2 is to be separated from the cartridge, the locking state is released by applying a predetermined force to the release preventing member 4 in the outward direction of the lower case 1, and then the release preventing member 4 is removed. Sliding moves to the outer side of the lower case (1) to take out the disk (2).

On the other hand, the release preventing member 4 is configured to slide on both sides, as well as to selectively prevent one side departure preventing member 4 is fixed and the other side leaving prevention member 4 configured to slide to move the other side to prevent sliding It goes without saying that the disk 2 can also be mounted or removed from the member 4 side.

The structure of this embodiment of the present invention is to move the disk (2) by sliding only the two or one side of the separation prevention member 4 in the state of fixing the left and right upper cases (3a, 3b) of the components installed on the upper surface of the lower case of the disc cartridge. Since the structure of removing) minimizes the portion where the movement occurs, it is possible to prevent the overall shape deformation and to maintain the overall rigidity of the cartridge even in the process of removing the disk (2).                     

In addition, the structure minimizes damage to the cartridge when an external shock or the like occurs in the process of removing the disk 2.

In other words, when the disc 2 is mounted on or removed from the cartridge, only the escape preventing member 4 is slidably moved, so that the moving area of the moved portion is narrowed, thereby preventing damage over a large area of the cartridge.

On the other hand, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made without departing from the spirit of the invention.

As described above, according to the present invention, the disc cartridge can be easily opened and closed so that the disc can be detached from the cartridge or mounted therein.

Accordingly, the disc cartridge of the present invention provides a convenience that can be effectively applied not only to a storage and reproducing apparatus which can be inserted in a state where the disc is combined, but also to a portable storage and reproducing apparatus which can insert only a single object of the disc. do.
