Description

明 細 記憶媒体の保護カバー 技術分野  Description Protective cover for storage media
本発明は、 〇0ゃ0 0を代表とし、 円盤形状であって、 少なくとも その片面において記憶の入力、 出力がなされる記憶媒体の表 (ひょう) 面を、 物理的に保護する保護カバーであって、 記憶の出入力をする面ま たはその反対側の面を保護すると共に、 記憶媒体を記憶出入力装置によ り駆動中においても、 記憶媒体に装着可能である保護カバーに関するも のである。 背景技術  The present invention relates to a protective cover for physically protecting a surface (hail) of a storage medium on which at least one side is used for inputting and outputting of memory, at least one side of which has a disk shape, typically represented by 〇0 ゃ 00. The present invention relates to a protective cover that protects a memory input / output surface or a surface on the opposite side, and can be attached to a storage medium even while the storage medium is being driven by the storage input / output device. . Background art
近年のコンピュータ一は、 O S ( Operation System ) が G U I (Graphical User Interface) 化し、 その操作が非常に簡単になったこ とにより、 企業や一般家庭で広く受け入れられるようになり、 急速な低 価格化とィン夕一ネッ卜の広がりとが相乗的に普及に拍車をかけ、 需要 の拡大に伴うハード面、 ソフト面における技術の向上ゃネッ 卜ワークの 発展はまさに日進月歩であり、 その進歩の加速度は予測の付かない時代 となってきた。  In recent years, computers have become widely accepted by companies and ordinary households due to the fact that the OS (Operation System) has become a GUI (Graphical User Interface) and its operation has become extremely simple. The expansion of the network has spurred the spread of the network synergistically, and the improvement of the hardware and software technologies accompanying the expansion of demand. The times have come to be unpredictable.
さて、 近年のこのようなコンピューターを中心としたマルチメディァ の急速な進歩に大きく寄与しているものに C Dや D V Dと言った光学式 を中心とした記憶媒体 (以下 「C D等」) がある。  By the way, what has greatly contributed to the rapid progress of such computer-based multimedia in recent years is optical storage media such as CD and DVD (hereinafter “CD” etc.).
特に、 C Dにおいては製造の容易性および低コスト、 C D— R O Mド ライブの高普及率、 取扱の容易性、 現時点における汎用デ一夕量との合 致性または記憶の不揮発性といった多くの利点を有することから、 C D — ROMを始めとして、 CD— Rや CD— RWなどといった形態で、 現 在もっとも汎用されている媒体と言える。 これに近い構造である DVD は汎用デ一夕量の増加に伴い、 その地位を CDと分かち合い、 やがては 台頭して行くことが予想されている。 In particular, CDs have many advantages such as ease of manufacture and low cost, high penetration of CD-ROM drives, ease of handling, compatibility with general-purpose data storage at present, or non-volatile storage. From having a CD — Media such as ROM, CD-R and CD-RW are the most widely used media at present. DVDs, which have a structure similar to this, are expected to share their position with CDs as the amount of general-purpose data increases, and eventually to rise.
この CD等は、 記憶を保持している記憶面があり、 その上に比較的厚 く、 透明な樹脂層を施した記憶出入力面がある。 以下、 本出願において は便宜上 「記憶出入力面」 を 「おもて面」、 「記憶面」 を 「裏面」 と称す る。  This CD etc. has a memory surface that holds the memory, and a memory input / output surface with a relatively thick and transparent resin layer on it. Hereinafter, in the present application, for convenience, the “memory input / output surface” is referred to as “front surface”, and the “memory surface” is referred to as “back surface”.
このおもて面は露出した樹脂で覆われていることから物理的に脆弱で、 取り扱いによっては損傷する危険があり、 一旦損傷してしまうと、 記憶 の出入力に不具合が生ずる結果となる。 そのため、 運搬や収納の際に、 このおもて面を保護する目的で数多くの収納容器が提案されている。 し かしながら、 CD等は使用するに当たりこのような収納容器から取り出 すことが必須となるため、 駆動装置である CDドライブ装置等に装填す る際などに、 損傷してしまう危険を回避することができない。  The front surface is physically fragile because it is covered with exposed resin, and there is a danger of being damaged by handling. Once damaged, this can result in malfunctions in memory input and output. Therefore, many storage containers have been proposed for the purpose of protecting the front surface during transportation and storage. However, CDs must be taken out of such a storage container before use, so there is no risk of damage when loading them into a drive such as a CD drive. Can not do it.
本出願人は、 たとえ CD等のおもて面にこのような回避できない損傷 が生じても、 これを研磨して再生することができる非常に有効な手段を PCT/J P 97/00633で示している。  The applicant has shown in PCT / JP 97/00633 a very effective means of polishing and regenerating such unavoidable damage even on the front side of a CD or the like. I have.
一方、 裏面は記憶が書き込まれ、 しかも通常はラベルが貼られている ため、 樹脂面が露出しているおもて面に比べ、 耐久性があるものと考え られがちである。 しかしながら、 ラベルから記憶部分までの距離はほん の僅かであり、 非常に浅い傷であっても、 記憶自体に損傷が及び、 しか もこのような損傷は上記した研磨再生手段を適用できない。 その結果と して CD等は記憶を読み取ることができないという致命的な損傷を得る ことになる。  On the other hand, the back side has memory written on it and is usually labeled, so it is often considered to be more durable than the front side where the resin surface is exposed. However, the distance from the label to the memory portion is very small, and even a very shallow scratch can damage the memory itself, and such damage cannot be applied by the above-mentioned polishing and regenerating means. As a result, CDs and the like suffer catastrophic damage that their memory cannot be read.
このような例としては、 図書館やレンタルショップではこの裏面にバ 一コードラベルなどを貼りつける必要があるものの、 これらを何らかの 理由で取り除く際、 ラベルの一部も剥がしてしまい、 記億そのものに損 傷を与えてしまう場合や、 不用意に裏面に書き込みを行って、 その筆圧 で記憶に損傷を与えてしまう場合などがある。 For example, a library or rental shop might use Although it is necessary to attach a code label, etc., when removing these for some reason, a part of the label may be peeled off, damaging the storage unit itself, or writing on the back side carelessly In some cases, the pen pressure may damage the memory.
そこで、 そのような裏面への致命的な損傷を回避するために、 裏面に 損傷しにくい素材を貼り付け、 これにより保護しょうとするものなどが 提案されている (特開平 9 - 1 1 5 2 6 0号の公開公報など)。 しかしな がら、 このように裏面にカバ一を単に貼り付ける方法では別の問題が発 生する。 すなわち、 何らかの理由でこの硬いカバーを取り除かなくては ならない場合、 剥がすことによりラベルと共に、 記憶部分まで剥がれて しまって、 記憶そのものが失われてしまう。  Therefore, in order to avoid such catastrophic damage to the rear surface, a material that is hardly damaged is attached to the rear surface, and this is intended to protect it (Japanese Patent Laid-Open No. 9-11152). 60 publication). However, another problem arises with the method of simply attaching the cover to the back surface in this way. In other words, if the hard cover must be removed for some reason, the label will be peeled off along with the label, and the memory itself will be lost.
また、 このような不具合を改善する目的で、 保護膜の一部分だけを貼 着して、 ラベル面への影響を防止するものも提案されている (特開平 9 - 3 2 6 1 7 5号の公開公報)。 しかしな力 Sら、 このような保護膜の貼着 では、 回転速度が年々速くなるドライブ装置では、 剥離の危険があり、 剥離するとドライブ装置に大きな影響を与えかねない。 本発明は、 上記したような、 従来技術における問題を一挙解決するた めに、 発明者らが鋭意研究の結果開発したもので、 C D等の記憶媒体の 表 (ひょう) 面を損傷から確実に保護すると共に、 記憶出入力装置に装 填中においても記憶媒体に装着可能で、 その作動に影響を与えることな く、 しかも着脱が自在にできる記憶媒体の保護カバ一を提供することを 目的としている。 発明の開示  Further, for the purpose of remedying such a problem, a method has been proposed in which only a part of the protective film is adhered to prevent the influence on the label surface (see Japanese Patent Application Laid-Open No. 9-326261). Published gazette). However, with such a protective film, there is a danger of peeling in a drive device whose rotational speed is increasing year by year, and the peeling may have a great effect on the drive device. The present invention has been developed by the inventors as a result of intensive research in order to solve the above-mentioned problems in the prior art at once, and ensures that the surface of a storage medium such as a CD is not damaged. An object of the present invention is to provide a protective cover for a storage medium that can be attached to a storage medium while being protected and can be attached to and detached from the storage medium without affecting its operation. I have. Disclosure of the invention

C Dなどを代表とする、 榭脂面で覆われた記憶出入力面であるおもて 面と、 記憶が書き込まれた記憶面であり、 通常はラベルが貼付されてい る裏面とからなる記憶媒体の表 (ひょう) 面を保護し、 損傷による記億 の喪失を確実に防止すると共に、 C Dドライブなどの記憶出入力装置に 装填中でも、 その作動に影響をほとんど与えることがないものである。 しかも、 必要に応じて記憶媒体からの着脱が自在で、 その際にラベル面 すなわち記憶面に一切影響を及ぼすことのないものである。  A storage medium, such as a CD, consisting of a front surface, which is a memory input / output surface covered with a resin surface, and a storage surface, on which the memory is written, and which is usually labeled with a label. It protects the surface of the surface, prevents loss of memory due to damage, and has little effect on its operation even when it is loaded into a storage device such as a CD drive. In addition, it can be freely attached to and detached from the storage medium as needed, and in that case, the label surface, that is, the storage surface is not affected at all.
具体的には、 C D等の記憶媒体の片面を覆って保護する面保護部と、 その外周部を覆って密着すると共にこれを保持する外周被覆部と、 係止 爪や粘着材などによる記憶媒体への装着手段とから構成され、 その全体 が C Dドライブ等への装填において障害とならないように、 非常に薄く 且つ保護機能を奏し得る素材で形成されている。  More specifically, a surface protection portion that covers and protects one side of a storage medium such as a CD, an outer periphery covering portion that covers and adheres to the outer periphery thereof, and a storage medium that includes a locking claw or an adhesive material. It is made of a very thin and protective material so that it does not hinder the loading of a CD drive or the like.
たとえば、 下記に示す C D用の保護カバーにあっては、 面保護部とし て、 ラベルが貼着された裏面と同形状の薄い樹脂で形成され、 C Dの中 心にあるラッチ係合穴径以上の直径の中心孔が形成され、 C Dの裏面と はラベル以外の部分で粘着するように設けられている。 一方、 外周被覆 部は面保護部と連続的に一体形成され、 さらに、 係止爪が C Dの外周部 からおもて面の僅かな部分に周りこむように非常に薄く形成されている。 これにより、 C Dとこの保護カバーは一体化し、 薄い素材で形成され ているため、 C Dドライブでの回転に影響を与えることはない。 For example, in the protective cover for a CD shown below, the surface protection part is made of thin resin with the same shape as the back surface on which the label is attached, and is larger than the diameter of the latch engagement hole in the center of the CD. A central hole with a diameter of is formed, and is provided so that it adheres to the back surface of the CD at parts other than the label. On the other hand, the outer peripheral covering portion is formed continuously and integrally with the surface protection portion, and the locking claw is formed on the outer peripheral portion of the CD. It is formed to be very thin so as to surround a small part of the front surface. As a result, the CD and this protective cover are integrated and made of a thin material, so that rotation in the CD drive is not affected.
保護カバーの材質としては、 成形の容易性、 可撓性、 強度、 展性など を考慮すると樹脂または金属が望ましい。 とくに、 樹脂にあっては、 成 形の容易性からはポリプロピレンが好適であるが、 完全に透明なものが 少ないため裏面の保護のためには有効である。 また、 塩化ビニルゃスチ ロールは透明性と可撓性の面で優れているため、 おもて面を保護する力 バーとして使用することも可能である。  As the material of the protective cover, resin or metal is preferable in consideration of ease of molding, flexibility, strength, malleability, and the like. In particular, for resin, polypropylene is preferable from the viewpoint of easiness of molding, but it is effective for protecting the back surface because few transparent resins are completely transparent. In addition, since polyvinyl chloride is excellent in transparency and flexibility, it can be used as a power bar to protect the front surface.
製造に当たっては、 表裏面からの両面プレスによる成形も可能である が、 樹脂にあっては片面からの精密な真空射出成形をもってすれば、 容 易に形成できる。 以下、 本発明の各実施例を図面に基づいて説明する。  In production, molding by double-sided press from the front and back sides is also possible, but resin can be easily formed by precision vacuum injection molding from one side. Hereinafter, embodiments of the present invention will be described with reference to the drawings.
実施例 1 Example 1
第 1図に示すように、 本実施例の保護カバー 1は、 C D (コンパクト ディスク) 2を保護するものであり、 その全体がポリプロピレンで一体 形成され、 C D 2の裏面 2 1に密着する面保護部 1 1と、 外周部 2 2を 覆う外周被覆部 1 2とから構成され、 面保護部 1 1の中心には C D 2の ラッチ係合穴 2 3の直径より僅かに大きい中央穴 1 3が形成されている c 面保護部 1 1は約 0 . 2 mmの厚さで、 外周被覆部 1 2は厚さ約 0 . 2 mm溝幅約 1 . 2 mmに形成されている。 As shown in FIG. 1, the protective cover 1 of the present embodiment protects a CD (compact disc) 2, which is integrally formed of polypropylene, and which is in close contact with the back surface 21 of the CD 2. A central hole 13 slightly larger than the diameter of the latch engagement hole 23 of the CD 2 is formed at the center of the surface protection portion 11. The formed c- plane protective portion 11 has a thickness of about 0.2 mm, and the outer peripheral coating portion 12 has a thickness of about 0.2 mm and a groove width of about 1.2 mm.
中央穴 1 3の周りの面保護部 1 1には粘着部 1 4が設けられて、 C D 2の記億収納域外である中心非書込み部 2 4に粘着するように設けられ ている。  An adhesive portion 14 is provided on the surface protection portion 11 around the central hole 13 so as to adhere to the central non-writing portion 24 outside the storage area of the CD 2.
また、 外周被覆部 1 2の先端には、 内周方向に僅かに織り返した環状 の係止爪 1 5が形成されており、 C D 2に装着した際に、 おもて面 2 5 側に僅かにはみ出して、 C D 2を保持するように設けられている。 この 係止爪 1 5は厚さが 0 . 2 mmで、 爪幅が約 0 . 2 mmである。 したが つて、 爪幅はおもて面 2 5の外周部分の記憶収納域外である無データ部 分 2 5 aを係止する。 In addition, at the tip of the outer circumference coating part 12, an annular shape slightly woven in the inner circumference direction The locking claws 15 are formed so as to slightly protrude toward the front surface 25 side when mounted on the CD 2 so as to hold the CD 2. The locking claw 15 has a thickness of 0.2 mm and a claw width of about 0.2 mm. Accordingly, the claw width locks the non-data portion 25a outside the storage area on the outer peripheral portion of the front surface 25.
C D 2に保護カバー 1を装着するにあたっては、 外周被覆部 1 2にじ D 2の外周部 2 2を嵌めこむようにして押しこむ。 全体が嵌まり込んだ 状態で、 第 2図に示すように係止爪 1 5がおもて面 2 5の縁の部分を押 え、外周被覆部 1 2が C D 2の外周部 2 2を保持した状態となると共に、 粘着部 1 4を中心非書込み部 2 4に押し当てて粘着させることにより、 C D 2と保護カバー 1とは一体化して互いに動かなくなる。  When attaching the protective cover 1 to the CD 2, the outer peripheral portion 22 of the D 2 is pushed into the outer peripheral covering portion 12 so as to be fitted. With the whole fitted, the locking claw 15 presses the edge of the front surface 25 as shown in FIG. 2, and the outer peripheral covering portion 12 holds the outer peripheral portion 22 of the CD 2 as shown in FIG. The CD 2 and the protective cover 1 are integrated and immovable with each other by being held and pressing the adhesive portion 14 against the central non-writing portion 24 to adhere.
この保護カバー 1を装着した C D 2を C Dドライブ等 (図示せず) に 装填して、 記憶の出入力を行う際には、 C Dドライブ等にラッチを有す るものにあっては、中央穴 1 3がラッチ係合穴 2 3より大きいことから、 通常と同様にラッチをラッチ係合穴 2 3に係合させることにより、 十分 な回転を得られる。 また、 ラッチを有しない C Dドライブ等であっても、 C D 2と保護カバー 1とは一体化しており、 しかも保護カバ一 1全体が 非常に薄い素材で形成されていることから、 その作動に影響を及ぼすこ とはない。  When the CD 2 with this protective cover 1 is loaded into a CD drive or the like (not shown) and data is input / output, if the CD drive or the like has a latch, the center hole is used. Since 13 is larger than the latch engagement hole 23, sufficient rotation can be obtained by engaging the latch with the latch engagement hole 23 as usual. Even in the case of a CD drive or the like that does not have a latch, the operation of the CD 2 and the protective cover 1 are affected because the protective cover 1 is integrated and the entire protective cover 1 is made of a very thin material. Has no effect.
また、 保護カバー 1を C D 2に装着した状態では、 面保護部 1 1にラ ベルを貼ったり、 ペンで書込みを行なっても記憶面に影響を与えること は一切ない。  Also, when the protective cover 1 is attached to the CD 2, even if a label is attached to the surface protective portion 11 or writing is performed with a pen, the memory surface is not affected at all.
さらに、 この保護カバー 1は容易に C D 2から取り外すことが可能で あるため、 従来生じていた記憶面 (裏面のラベル) の剥離といった問題 は生じない。 実施例 2 Further, since the protective cover 1 can be easily removed from the CD 2, the problem of peeling of the storage surface (label on the back surface) which has conventionally occurred does not occur. Example 2
第 7図に示すように、 本実施例 2の保護カバ一 3は、 CD (図示せ ず) を保護するものであり、 その全体が透明度の高いスチロール樹脂で 一体形成され、 CDのおもて面に密着する面保護部 3 1と、 CDの外周 部を覆う外周被覆部 32と、 CDの裏側に僅かにはみ出して、 CDを保 持する複数の円弧状の係止爪 3 5とから構成され、 面保護部 3 1の中心 には CDのラッチ係合穴の直径より僅かに大きい中央穴 33が形成され ている。 面保護部 3 1は約 0. 2mmの厚さで、 外周被覆部 32は厚さ 約 0. 2 mm溝幅約 1. 2 mmに形成されている。  As shown in FIG. 7, the protective cover 3 of the second embodiment protects a CD (not shown), and the whole is integrally formed of a highly transparent styrene resin, and the front of the CD is protected. It consists of a surface protection part 31 that is in close contact with the surface, an outer circumference covering part 32 that covers the outer circumference of the CD, and a plurality of arc-shaped locking claws 35 that protrude slightly behind the CD and hold the CD. A central hole 33 slightly larger than the diameter of the CD latch engagement hole is formed at the center of the surface protection portion 31. The surface protection portion 31 has a thickness of about 0.2 mm, and the outer peripheral coating portion 32 has a thickness of about 0.2 mm and a groove width of about 1.2 mm.
係止爪 3 5は、 切り欠き 36を隔てて隔置された実質的環状であり、 その厚さは約 0. 2mm、 爪幅は約 0. 5mmである。 したがって、 上 記実施例 1の爪幅より大きく、 さらに確実に係止することにより、 粘着 手段を用いることなく CDを十分に保持できる。  The pawl 35 has a substantially annular shape separated by the notch 36, and has a thickness of about 0.2 mm and a pawl width of about 0.5 mm. Therefore, the CD is sufficiently larger than the nail width of the above-described embodiment 1 and can be sufficiently held without using an adhesive means by locking more securely.
この保護カバー 3を CDに装着するに当たっては、 CDの表面を柔ら かい布とアルコールなどを使用して汚れを落とし、 乾燥させた後に、 そ のおもて面が面保護部 3 1に面するように押し付ける。 切り欠き 36の 存在により、 係止爪 3 5が開き、 容易に CDが嵌め込まれる。 CDが保 護カバ一 3内に収まることにより、 係止爪 35が元に戻り、 CDの裏面 を保持する。  When attaching this protective cover 3 to a CD, use a soft cloth and alcohol to clean the surface of the CD, dry it, and then the front side of the cover faces the surface protection section 31. And press it. Due to the presence of the notch 36, the locking claw 35 is opened, and the CD is easily fitted. When the CD fits in the protection cover 3, the locking claw 35 returns to its original position, and the rear surface of the CD is held.
上記したように本実施例の保護カバ一 3は、 CDのおもて面と同じ材 質のスチロール製であるため、 透明度が高く、 記憶の出入力を妨げるも のではないため、 C Dに装着した状態でドライブ等に入れて使用するこ とが可能である。  As described above, since the protective cover 3 of this embodiment is made of styrene, which is the same material as the front surface of the CD, the cover is high in transparency and does not hinder the input / output of the memory. It can be used in a drive, etc. in a state where it has been removed.
尚、 本実施例の保護カバ一 3の形状を各第 8〜 1 1図より明確に示し ている。  Incidentally, the shape of the protective cover 3 of this embodiment is clearly shown in FIGS. 8 to 11.
