[Problems to be Solved by the Invention] The conventional optical disk case as described above has been described above. The following reasons can be considered for the structure. First, widely used now Read-only optical discs such as existing CDs, DVD-ROMs and DVD-VIDEOs An optical disk case that stores a disc, such as the title or Between the bottom plate 63 and the middle case 74, there is no need to rewrite the contents. It has a structure that makes it difficult to remove the lower label 73 and spine label surface 73a when they are sandwiched. However, this is because there is no major obstacle in practical use, and rather cost is prioritized.

Next, in the case of the recording type optical disk case shown in FIG. 7, a built-in optical disc is used. The cartridge is a sealed type because the disk supports recording, erasing, rewriting, etc. It is structured. Sealed to prevent recording errors due to dust and fingerprints This was because it was initially thought that a structure was needed.

However, in recent years, there is a market need for a lower cost recording type optical disk. Due to the rise of the market, the naked CD-R / RW which is not sealed by the cartridge Has penetrated into the market and made a market record. This flow is DVD-R / RW, DVD- The same applies to RAM, and at the beginning of standardization, it was standardized with a structure that was enclosed in a cartridge. However, recently, bare recordable optical discs have become the mainstream of the market.

In the above-mentioned flow, the most popular and low-cost read-only optical disk The bare recordable optical disk case is stored in the optical disk case that has been used for The combination of being done is now well established. However, this playback-only optical disc A conventional optical disc case, such as that shown in FIG. For discs, the functionality is very insufficient and improvement is required for the following reasons. Has been.

Recently, a TV image is recorded using a DVD-RAM or a DVD-RW. DVD recorders for recording are rapidly becoming popular. This DVD recorder is conventional Record using the advantages of digital recording compared to analog recording like VTR Since it is easy to edit images and there is no image deterioration due to dubbing, It is expected to become a product that completely replaces the later VTR. Conventional V In TR, the width of the tape is large, so about 20 mm * 1 on the back of the tape cartridge. There is a spine label side with a large area of 50 mm, and the spine made of paper stuck to it Easily write down the recorded contents with a pencil on the label side, or erase with an eraser It was possible to rewrite. In addition, VTR tapes such as bookshelves and racks You can easily find the desired VTR tape by relying on the label on the back cover even if you have many It was possible to put it out. Such behavior is already deeply rooted in the user. Therefore, it will be a recordable DVD disc that will replace VTR tapes in the future. Similar functions are required even in the future. However, as described above, the lower label 73 and The spine cover label surface 73a obtained by bending the end portion of the lower label 73 at a right angle is an optical disk case. The lower label 73 and spine label surface 73a are written on the back cover because Each time it is replaced, the optical disc case is disassembled and the lower label 73 is placed outside the optical disc case. And then reassemble the optical disk case after rewriting. However, there is a new problem in that it requires extremely troublesome work.
