Abstract

PURPOSE: Manufacturing a disc cartridge has many process. It is very easy to separate or lost parts of it during this process. It needs manufacturers' much attentions and process time and reduces productivity rate. CONSTITUTION: Form a separation preventing part(39) covering a body part(28b) of sliders(28,36) on the second lib(32b) of the disc cartridge. By improving the shape of the separation preventing part of the cartridge, it reduces manufacturing time of the spring restores disc cartridge shutter and the slider and improves the productivity.

Description

Disk Cartridge

The present invention relates to a disc cartridge, and more particularly to a disc cartridge configured to shorten the assembly time.

Typically, an optical disk has a bare disk when it has relatively physically safe information recording surfaces such as compact disk-ROM and digital versatile disk-ROM (DVD-ROM) for reproduction only. (Bare disk) is used as a single disk (without a cartridge). On the other hand, in the case of a rewritable disc, that is, a compact disc-Recordable (CD-R) and a digital versatile disk-RAM (DVD-RAM), a relatively weak recording surface is used. In order to prevent contamination and damage of the information recording surface by a source of contamination, it is a general trend to use it mounted on a cartridge. The disc cartridge will be described below.

1, the cartridge according to the prior art is a case 3 for protecting the disk 4, and a window 6 formed in a predetermined size in the case 3 for recording / reproducing information on the disk 4; ), A shutter 12 that protects the disk 4 from the pollution source flowing into the window 6, and first and second sliders 7 and 9 that move in correspondence with the movement of the shutter 12. . The case 3 mounts a disk 4 capable of recording / reproducing a large amount of information, thereby protecting the disk 4 from external contamination and preventing damage to the disk 4 due to external impact. . In addition, the case 3 is provided with a window 6 having a predetermined size for reproducing information recorded on the disk 4 or for recording information on the disk 4. In this case, the shutter 12 is formed to prevent the external pollutant from entering the disk 4 via the window 6. On the other hand, referring to the operation according to whether the shutter 12 is opened or closed, when the cartridge is loaded into a disc driver (not shown) to record / reproduce information on the disc 4, a shutter opener (not shown) is used. The shutter 12 is moved to the left or right side of the case 3 to open the window 6 (that is, to expose the information recording surface of the disc). In this case, the one slider 7 or 9 corresponding to the moving direction of the shutter 12 is in contact with the shutter 12 to move in the same direction as the shutter 12, and the other slider 9 or 7 has its own. Will maintain its position. Referring to the slider moved in conjunction with FIG. 2A, the guide hook 7a of the slider 7 is moved along the guide groove 16 formed between the side wall of the case 3 and the first rib 10a. Meanwhile, referring to FIG. 2B, a slider fixing protrusion 18 is formed between the first rib 10a and the second rib 10b of the case 3 to fix the slider not to progress. Accordingly, the slider 9 or 7 on the other side maintains its position. On the other hand, when ejecting a cartridge from a disk driver (not shown), the cartridge is separated from the shutter opener (not shown), so that the shutter 12 returns to its original position and closes the window 6. In this case, the shutter 12 returns to its original position by the restoring force of the spring 10 mounted on the first and second sliders 7, 9. The spring 10 is mounted to the fixed hooks 7c and 9c of the first and second sliders. On the other hand, in the assembling process of the disc cartridge having such a structure, the process of attaching the spring 10 between the first and second sliders 7, 9 takes a lot of time. In detail, the spring 10 is mounted on the fixed hook 7c of the first slider, and then mounted on the fixed hook 9c of the second slider while being tensioned by applying a predetermined force to the spring. In this process, the spring 10 has a predetermined restoring force, so that the slider can be separated and detached from the case 3. This makes it difficult for the worker to mount the spring 10 to the slider without careful attention, and also requires a lot of time in the assembly process because the slider must be separated and detached from the case and reassembled. Is being derived.

Accordingly, an object of the present invention is to provide a disk cartridge configured to shorten the assembly time.

In order to achieve the above object, the disc cartridge according to the present invention includes a slider detachment prevention means for preventing separation and detachment of the slider.

Other objects and features of the present invention other than the above object will become apparent from the description of the embodiments with reference to the accompanying drawings.

With reference to Figures 3 to 4 will be described a preferred embodiment of the present invention.

Referring to FIG. 3, a disc cartridge according to the present invention includes a case 23 protecting a disc 24 and a window formed in a case 23 at a predetermined size for recording / reproducing information on the disc 24. (26), shutters (34) for protecting the disk (24) from contamination sources entering the window (26), first and second sliders (28,36) moving in response to movement of the shutters (34); And a slider departure preventing part 38 for preventing separation of the sliders 28 and 36. Since the operation of the slider according to whether the shutter 34 is opened or closed is the same as in FIG. 1, a detailed description thereof will be omitted. The guide groove 30 formed between the side wall of the case and the first rib 32a guides the slider guide hook 28a when the slider moves. In addition, referring to FIG. 4, the slider departure prevention part 38 will be described. The slider departure prevention part 38 is extended from the second rib 32b to a predetermined length so as to be formed on the upper portion of the slider body part 28b. It is formed in the shape of "a" to prevent the sliders 28 and 36 from being separated or separated from the case 23. Accordingly, in the cartridge assembly process, the slider is prevented from being separated or detached from the case in the process of mounting the spring 40 between the first and second sliders 28 and 36, thereby shortening the cartridge assembly time. Yield is improved.

As described above, the disc cartridge according to the present invention has an advantage that the assembly time can be shortened by improving the process yield by forming the slider detachment preventing portion for preventing the separation and detachment of the slider in the cartridge.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the technical spirit of the present invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification but should be defined by the claims.
