Description

本発明は、光ピックアップのレンズをクリーニングするクリーニングディスクに関するものである。The present invention relates to a cleaning disk for cleaning a lens of an optical pickup.

光ピックアップレンズクリーニング用のディスクには従来から光ディスク、及光磁気ディスク等が用いられており、これらディスクのＴＯＣエリア近傍、又はプログラムエリア内周近傍に光ピックアップレンズ清掃用のクリーニング部材が少なくとも１つ設けられている。このクリーナーを再生装置で再生することにより、クリーニングディスクが回転し対物レンズとブラシが接触しクリーニングを行う。
この様にディスクが回転することでクリーニングする方式では、クリーニングディスクに設けられたブラシが対物レンズ以外のプレーヤ内部のメカ等にも接触する場合が考えられる。その結果メカ部の油や汚れがブラシに付着し、その汚れ等が対物レンズに付くこととなり逆効果となる場合がある。Conventionally, optical pickup lenses and magneto-optical discs have been used as optical pickup lens cleaning discs. At least one cleaning member for optical pickup lens cleaning is provided in the vicinity of the TOC area or the inner periphery of the program area of these discs. Is provided. When this cleaner is reproduced by a reproducing apparatus, the cleaning disk rotates and the objective lens and the brush come into contact with each other for cleaning.
In the method of cleaning by rotating the disc in this way, it is conceivable that the brush provided on the cleaning disc may come into contact with a mechanism inside the player other than the objective lens. As a result, the oil or dirt of the mechanical part adheres to the brush, and the dirt or the like adheres to the objective lens, which may have an adverse effect.

解決しようとする課題は、クリーニングディスクを回転させクリーニングする事で、発生し易いレンズクリーニングへの弊害をなくす点にある。The problem to be solved is to eliminate the harmful effects of lens cleaning that are likely to occur by rotating and cleaning the cleaning disk.

本発明では、これら従来製品の問題点を解決すべく、クリーニングディスクを再生装置へ装填した状態で再生装置ディスク挿入口から外側へ、一定の長さを持った弾性素材を、クリーニングディスクの外周近傍へ設けてある。主に弾性素材はスプリングや伸縮性に富んだ素材を用いる。前記クリーニングディスクはクリーニング部材を設けた部位を含め他の部分と同じように、レーザー光を反射する仕様とするか、該ディスクを再生装置に装填後、クリーニング部材を設けてある部位がピックアップレンズに接触しない程度の位置へずらすように構成することでレーザー光を遮蔽することもなくなるので、該クリーニングディスクをプレーヤへ装填すると初期動作に伴いディスクは回転しようとする。しかし、前記クリーニングディスクに設けた弾性素材が再生装置ディスク挿入口に当たりストッパーとなって、クリーニングディスクの回転力が弾性素材の反発力より勝るところまでは回転するが、それ以上の負荷が、かかった瞬間に弾性素材の復元力で元の位置まで戻される。しかし、次の瞬間に又同様の回転をしようとするが、又弾性素材の復元力で戻されてしまう。この一連の動作を繰り返すことにより、クリーニング部材が光ピックアップレンズ面上で反復動作し、回転することなく自動でクリーニングが行われる。In the present invention, in order to solve the problems of these conventional products, an elastic material having a certain length is provided in the vicinity of the outer periphery of the cleaning disk in a state where the cleaning disk is loaded in the playback apparatus and outward from the playback apparatus disk insertion slot. Is provided. Mainly elastic material is spring and elastic material. The cleaning disk is designed to reflect laser light in the same manner as other parts including the part where the cleaning member is provided, or the part where the cleaning member is provided becomes the pickup lens after the disk is loaded into the playback device. Since the laser beam is not shielded by being configured to be shifted to a position where it does not come into contact, when the cleaning disk is loaded into the player, the disk tends to rotate with the initial operation. However, the elastic material provided on the cleaning disk hits the playback device disk insertion slot and acts as a stopper, and the cleaning disk rotates until the rotational force of the elastic material exceeds the repulsive force of the elastic material. Instantly return to the original position by the restoring force of the elastic material. However, the same rotation is attempted again at the next moment, but it is returned by the restoring force of the elastic material. By repeating this series of operations, the cleaning member repeatedly operates on the optical pickup lens surface, and the cleaning is automatically performed without rotating.

又、前記クリーニングディスクのクリーニング部材を設けた近傍のみレーザー光を反射しない仕様にし、該ディスクを再生装置に装填しその箇所がレンズ上に来るように構成すると、レーザー光の反射が得られないことで初期動作を行わないので、当然該ディスクは回転せずに再生装置に装填されたまま静止状態となる。静止状態から手動によりディスクを動かす為の紐と、紐を引いた後、紐を緩めると所定の位置まで戻すためのリターン用弾性素材等の部材とを一定の間隔をおいて、ディスク外周近傍に設けてある。ディスクを動かすための紐はクリーニングディスクを所定の範囲内で移動させる為に一定以上は引けない構造とし、再生装置ディスク挿入口より外へ出る長さを有している。ディスクを動かすための紐はこの紐を手前に引くと、クリーニングディスク弾性素材がスプリングの場合であれば再生装置ディスク挿入口の端に圧着され弓状に曲がり、次に紐を緩めると弾性素材の復元力によって元の位置へ戻る、伸縮性の弾性素材であれば、弾性素材の端に設けた防止ストッパーの働きにより、再生装置ディスク挿入口で引っかかった先のみが引っ張られ伸びるが、その後、弾性素材の復元力によって元の位置へ引き戻される、又紐を引く、紐を緩める、この一連の動作を繰り返すことにより、クリーニング部材が光ピックアップレンズ面上で反復動作し、回転することなくクリーニングが行われる。In addition, if the specification is such that the laser beam is not reflected only in the vicinity of the cleaning disk provided with the cleaning member, and the disc is loaded into a playback device and the spot is on the lens, the laser beam cannot be reflected. Since the initial operation is not performed, the disc naturally does not rotate and remains stationary while being loaded in the reproducing apparatus. A string for manually moving the disk from a stationary state and a member such as a return elastic material for returning to a predetermined position when the string is loosened after pulling the string are placed near the outer periphery of the disk at a certain interval. It is provided. The string for moving the disk has a structure in which the cleaning disk cannot be pulled beyond a certain level in order to move the cleaning disk within a predetermined range, and has a length that goes out from the reproducing apparatus disk insertion port. When the string for moving the disk is pulled forward, if the elastic material of the cleaning disk is a spring, it will be crimped to the end of the playback device disk insertion slot and bent into a bow shape. If it is a stretchable elastic material that returns to its original position by the restoring force, only the tip caught at the playback device disc insertion slot is pulled and extended by the action of the prevention stopper provided at the end of the elastic material. The cleaning member is repeatedly moved on the surface of the optical pickup lens by repeating this series of operations by pulling back the string by pulling the string, loosening the string by the restoring force of the material, and cleaning is performed without rotating. Is called.

本発明のクリーニングディスクは再生装置内で回転せずに、クリーニング部材が光ピックアップのレンズのみと接触しクリーニングができる構造とした。以上のように、本発明は従来製品では不可能であった対物レンズのみをクリーニングすることを可能とした事に利点がある。The cleaning disk of the present invention has a structure in which the cleaning member does not rotate in the reproducing apparatus and the cleaning member comes into contact with only the lens of the optical pickup and can be cleaned. As described above, the present invention has an advantage in that it is possible to clean only the objective lens, which is impossible with the conventional product.
