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 D mounted inside the cartridge, as shown in Figs.

That is, in the state where the disk D is accommodated inside the cartridge, when the disk D 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 D and made therein become an important concern so that both the use in the cartridge state and the use of the disc D as a single object can be made 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 disk from a disk cartridge, thereby implementing a disk cartridge which enables both the use in a cartridge state and the use as a single disk object. The purpose is.

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 formed with a window for drive access; An upper case installed at an upper portion of the lower case and having an exposed window formed at a central portion thereof to expose a label surface of the disk; Rotating ring is rotatably installed in the upper and lower cases, the outer ring of the disk is seated; Left and right shutters installed in the upper and lower cases so as to be interlocked with the rotary ring to open and close the window as the rotary ring is rotated; The disks are formed on the left and right shutters, respectively, and the edges of the disk are gripped when the left and right shutters are closed. When the left and right shutters are opened, the disks are moved in a direction away from the center of the disk. Flow prevention device for releasing; It is installed on one side of the upper and lower cases in a slide manner so as to be rotatable based on the center of the disk, and rotates the rotary ring as the rotary ring moves in a state of interference with the outer circumference of the rotary ring and Manual opening and closing module for opening the left and right shutter interlocked: provides a disk cartridge, characterized in that it comprises a.

By being caught by one end of the control slot (S: see Fig. 10) formed in the case (10, 20) further rotation is prevented.

On the other hand, when the rotating ring 30 is rotated, the interlocking protrusions 30a formed on the rotating ring 30 push and move the interlocking slots 41a and 42a formed on the left and right shutters 41 and 42. Accordingly, the left and right shutters 41 and 42 rotate about the rotation shafts 11a and 11b to open the windows W formed in the lower case 10 through the gaps spaced therebetween.

In addition, the left and right shutters 41 and 42 are opened to open the window W, and the flow preventing holes 45 provided in the left and right shutters 41 and 42 are far from the center of the disk D. Sliding in the direction to release the holding state of the disk (D).

Next, as shown in FIG. 10, when the separation preventing member 23 formed in the upper case 20 is pushed in a direction away from the center direction of the disk D, the separation preventing member 23 is the disk D. Outside the scope of).

Accordingly, the separation preventing protrusion 25 formed on the opposite side of the separation preventing member 23 in the disk D while the flow preventing device 45 and the separation preventing member 23 are deviated within the area of the disk D as described above. When the upper side is taken out through the exposed window 20a of the upper case 20, the disk D is easily separated from the disk cartridge.

On the other hand, the process of mounting the disk (D) in the disk cartridge, since the above-described separation process may be performed in the same way, a detailed description thereof will be omitted.

On the other hand, the window opening and closing process of the disc cartridge for recording and reproducing the disc in the state where the disc is mounted on the disc cartridge according to the present invention configured as described above are as follows.

As shown in Figure 4 and 5, the outer peripheral portion of the rotary ring 30, along with the locking groove 31 and the gear portion 32 and another operating groove 33 is further formed, the disc cartridge When inserted into the disc drive device, the window W formed in the disc cartridge is completely opened in cooperation with an opening member (not shown) installed inside the disc drive device to record and reproduce the disc D. FIG.

In more detail, when the disc cartridge is inserted into the disc drive device, the opening member presses the operation protrusion 73 of the locking lever 70 installed in the disc cartridge to lock the locking protrusion 71 to the locking groove of the rotary ring 30. Departure from (31).

Subsequently, when the disc cartridge is continuously inserted, the opening member rotates the rotary ring 30 in cooperation with the operation groove 33 and the gear 32 formed in the outer circumferential portion of the rotary ring 30.

Therefore, as the rotary ring 30 rotates, the interlocking protrusions 30a of the rotary ring 30 and the interlocking slots 41a and 42a of the left and right shutters 41 and 42 are interlocked with each other. , 42 is opened, and thus the window W formed in the lower case 10 is opened by a space in which the left and right shutters 41 and 42 are spaced apart from each other.

In other words, it becomes a state in which the disc D can be recorded and reproduced by the disc drive device from the disc cartridge.

As described above, by using the disk separating apparatus according to the present invention, the disk can be easily detached from the disk cartridge or mounted in the disk cartridge, and the disk cartridge can be prevented from being lost.

In addition, 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 capable of inserting only a single object of the disc. do.
