【発明の詳細な説明】
〔産業上の利用分野〕
本発明は光ディスク装置に関し、特に光ヘツド組立の中
の光学部品とレンズの汚れを防ぐ機能に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical disk device, and more particularly to a function for preventing contamination of optical components and lenses in an optical head assembly.
従来光ディスク装置の光ヘツド組立には、レンズ表面は
綿棒で直接拭いていたが、レンズの裏面及びヘッド組立
内部の光学部品は清掃できなかった。Conventionally, when assembling the optical head of an optical disk device, the surface of the lens was directly wiped with a cotton swab, but the back surface of the lens and the optical components inside the head assembly could not be cleaned.
上述した従来の光ディスク装置は、光ヘッドのレンズを
直接綿棒で拭くので専門の人でないと、ヘッド清掃がで
きないという欠点がある。また、光ヘツド組立内の光学
部品は清掃が不可能なので長時間使用すると汚れのため
光ディスク装置が動かなくなる欠点もある。The above-mentioned conventional optical disc device has a drawback in that the lens of the optical head is directly wiped with a cotton swab, and only a professional can clean the head. In addition, since the optical parts in the optical head assembly cannot be cleaned, there is also the drawback that the optical disc device may become unworkable due to contamination when used for a long period of time.
本発明の光ディスク装置は、ファンとフィルターとエア
タンクと一方に穴のあいたヘッド組立を有している。The optical disc device of the present invention includes a fan, a filter, an air tank, and a head assembly with a hole on one side.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第1図は本発明の一実施例の外形図である。FIG. 1 is an outline drawing of an embodiment of the present invention.
ファン1が回転するとエアーが外からヘッド組立内部に
向かって導入されるファン1からのエアーはフィルター
A2に入り空気中の汚れを取り除く。フィルターA2か
らの汚れてない空気はエアタンク3へ入れられる。エア
タンク3のヘッド組立4側には溝がある。また、ヘッド
組立4の底に穴(A−A部)がおいているほかは、この
溝は、ヘッド組立4でふさがれた状態になっている。When the fan 1 rotates, air is introduced from the outside toward the inside of the head assembly.The air from the fan 1 enters the filter A2 to remove dirt from the air. Clean air from filter A2 is admitted to air tank 3. There is a groove on the head assembly 4 side of the air tank 3. Further, except for the hole (A-A section) provided at the bottom of the head assembly 4, this groove is closed by the head assembly 4.
ヘッドが移動しても、この溝はヘッド組立4でふさがれ
た状態になるように、ツバ5が出ている。A flange 5 is provided so that this groove remains covered by the head assembly 4 even if the head moves.
溝に入ったエアーは、ヘッド組立4の底の穴に入る。ヘ
ッド組立4の底に入ったエアーは、再び、フィルターB
6によりさらにクリーンなエアーにし、ヘッド組立4の
中に入る。ヘッド組立4に入ったエアーは対物レンズ7
の両側よりヘッド組立4の外へ出る。The air that has entered the groove enters the hole at the bottom of the head assembly 4. The air that entered the bottom of head assembly 4 is sent to filter B again.
6 makes the air even cleaner and enters the head assembly 4. The air that has entered the head assembly 4 is sent to the objective lens 7.
exits the head assembly 4 from both sides.
以上説明したように本発明は、クリーンなエアーを強制
的にヘッド組立内部に入れることにより常にヘッド内部
が汚れない効果がある。さらに、対物レンズの周りもエ
アーが吹き出しているので対物レンズも汚れない効果が
ある。As explained above, the present invention has the effect of keeping the inside of the head always clean by forcing clean air into the inside of the head assembly. Furthermore, since air is blown out around the objective lens, the objective lens also has the effect of not getting dirty.
