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 pulled out by combining the lower case 1 and the upper case 3 by the screw S, loosen all the screws. You have to pay.

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 8 and the like 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, which can be easily mounted and detached from the inside of the cartridge 2 and made therein, to enable both the use in the cartridge state and the use as a single disc of the disc, has become an important concern.

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 seating the disk and a window for drive access; And an upper case consisting of a fixing part fixed to the lower case and a moving part which forms an exposed window when the fitting part is fixed and is slidably installed along both sides of the lower case. A cartridge is provided.                     

According to another aspect of the present invention for achieving the above object, a lower case provided with a pocket for seating the disk and a window for drive access; And an upper case comprising a fixing part fixed to the lower case and a movable part installed to be slidable along both sides of the lower case and rotatably installed at the end of the sliding. A cartridge is provided.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 4 to 9.

First, a disc cartridge according to a first embodiment of the present invention will be described with reference to FIGS. 4 and 5.

It is configured to include an upper case (3) made of a movable part (5) installed to be slidable along both sides of the case (1) and rotatably installed at the point where the sliding ends.

At this time, a guide part 500 having a guide hole 510 is formed on the side of the moving part 5, and a guide for guiding the movement of the guide part 500 on the inner surface of the lower case 1. The groove 100 is provided, and the guide protrusion 110 is formed to move relative in the guide hole 510 formed in the guide part 500 in front of the inner side of the lower case.

That is, the guide protrusion 110 serves to allow the moving part 5 to rotate in a state in which sliding of the moving part 5 to the front of the moving part is completed.

In addition, the diameter of the exposed window 10 is preferably smaller than the diameter of the disk 2 so that the separation of the disk 2 is prevented.

On the other hand, the disk cartridge is provided with a plurality of flow prevention holes (8) to prevent the flow in the cartridge of the disk 2 by holding the edge of the disk (2) when the moving part (5) is closed.

The flow prevention device 8 is to support the upper and lower edges of the disk 2 as the moving part 5 is closed, it is preferable to form a "c" in cross-section.

In particular, the flow preventing device 8 is preferably disposed to be spaced 120 or 90 degrees to each other around the disk (2), the flow preventing device 8 is the disk in the process of opening the moving part (5) It moves so that it may move away from the center of (2), and in the process of closing the moving part 5, the flow prevention opening 8 will be comprised so that it may move to the direction closer to the center of the disc 2. As shown in FIG.

Then, the moving part 5 and the lower case 1 of the upper case 3 in a closed state so that they are coupled to each other, so that the locking means is not provided to open naturally until the user releases the restriction.

At this time, the locking means is preferably provided at a sufficiently long distance from the hinge, as a locking method to form a locking projection on one side of the moving part 5 of the upper case 3 and lock the portion of the upper case 3 corresponding thereto. A groove is formed to allow snap fitting as a force of a certain amount or more is applied and vice versa to open.

On the other hand, the locking projection and the locking groove may have the same effect even if formed on the moving part 5 of the upper case (3) and the fixing part (4) of the upper case (3).

In addition, the locking means may be configured by a push button method or a slide method using a hook and a spring, which are 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.

With the disk 2 coupled to the cartridge, the disk 2 must be separated from the disk cartridge for use in a portable storage and playback device that only inserts a single disk medium.

That is, when the disk 2 is in the disk cartridge and the disk is to be removed from the cartridge, the moving part 5 constituting the upper case 3 of the disk cartridge is moved away from the fixing part 4. As shown in Fig. 5, the disc 2 is pulled out in a state where the disc 2 can be pulled out.

At this time, in order to remove the disk 2 from the cartridge, the locking state between the moving part 5 constituting the upper case 3 and the lower case 1 is released, and then the moving part constituting the upper case 3. (5) is pulled along both sides of the lower case (1), and then the moving unit (5) is rotated in the upper or lower direction again in the state that the sliding is completed.

In this case, when the disk 2 is pulled out, the interference between the disk 2 and the moving part 5 is effectively excluded, and thus the disk 2 can be gripped and easily removed.

Then, when the cartridge is opened and the disk 2 is removed, the flow preventing device 8 installed around the disk 2 and supporting the edge of the disk 2 has the disk 2 as the moving part 5 is opened. ) Away from the disc 2 by moving in a direction away from the center.

On the other hand, when the disk 2 separated from the disk cartridge is to be mounted in the cartridge for use in a state where the disk 2 is combined, the disk 2 is stored in the disk cartridge through the reverse process described above. ) Is embedded.

That is, in a state in which the movable part 5 is slid along both sides of the lower case 1, the disk 2 is seated on the lower case 1, and then the both sides are slid again by sliding the moving part 5. It is closed by sliding along.

At this time, in the process of closing the moving part 5, the flow preventing device 8 moves in a direction approaching the center of the disk 2, and when the moving part 5 is closed, the edge of the disk 2 is closed. Is supported by a flow stopper 8 in the form of a "c".

When the moving part 5 is completely closed, the moving part 5 and the lower case 1 constituting the upper case 3 are locked by the locking protrusion and the locking groove.

This method of the present invention is a slide and hinge structure which is generally widely used at present, and allows the user to attach and detach the disk 2 in a relatively friendly manner.

And, the present invention has the advantage that can easily implement the opening and closing structure by adopting the slide and the hinge structure.

Meanwhile, as described above, the lower case 1 of the disc cartridge in which the disc 2 is mounted or detached is blocked from the outside except for the part of the window W for accessing the drive to protect the recording surface of the disc 2. It has a structure, and a portion of the disc 2 is exposed through the window W for drive access at the time of recording and reproduction of the disc 2.

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 of the disc cartridge is opened by the operation of the reproducing apparatus, and thus the drive drive is connected to the recording surface of the disc 2 through the window (W). You can access it.

In short, the disk cartridge of the present invention is the overall shape in the state that the disk cartridge is opened by the upper case (3) is separated into a fixed portion (4) and the moving part (5), and the moving part (5) is rotated after sliding. In addition to preventing deformation, the overall rigidity of the cartridge can be maintained continuously in the process of removing the disk 2.

6 is a perspective view showing a disc cartridge according to a second embodiment of the present invention, in which case the area and shape of the moving part 5 and the fixing part 4 are different.

In other words, in this case, the moving part 5 and the fixing part 4 are provided with a portion for forming the exposure window 10, and both side guide parts for sliding the moving part 5 are formed long, thereby moving when opening and closing the cartridge. Sliding of the part 5 is made exactly without play.

7 is a perspective view showing a disk cartridge according to a third embodiment of the present invention, and FIGS. 8 and 9 are perspective views showing a disk cartridge according to a fourth embodiment of the present invention. Since there is no part which forms the exposure window 10 in the moving part 5 and the fixing part 4, exposure of the disc 2 is completely prevented when a cartridge is closed.

In addition, although schematically illustrated in FIG. 6 to FIG. 9, as the structure for sliding and rotating the moving part 5, the structure as shown in FIG. 5 may be adopted, as well as various other forms. Naturally, it is natural that the modified sliding structure can be applied.

For example, the structure of placing the guide groove on the upper surface of the lower case 1 with the guide portion 500 on the lower surface of the moving portion 5 rather than the structure of placing the guide portion 500 on the side of the moving portion 5. As a structure of the same concept, a structure having a guide groove on the lower surface of the moving part 5 and a guide part 500 on the upper surface of the lower case 1 is also possible.

And the structure of the sliding system by a roller and a guide rail can also be employ | adopted.

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 separated 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 a single object of the disc. Done.
