本発明は、光ディスク装置における書込み、読み出しヘ
ッドのレーザ光出射レンズのクリーニング機構付に係り
、特に光ディスク等の高密度記録再生装置に使用する光
ディスクカートリッジのクリーニング機構に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cleaning mechanism for a laser beam emitting lens of a writing/reading head in an optical disk device, and in particular to an optical disk used in a high-density recording/reproducing device such as an optical disk. The present invention relates to a cartridge cleaning mechanism.
従来の光ディスク装置では、光ディスクカートリッジを
挿入する事により、光ディスク装置内にもうけられた空
気圧縮ポンプを動かしその圧縮空気によりレーザ光出射
レンズ表面をクリーニングする機構がある。Conventional optical disc devices have a mechanism in which, when an optical disc cartridge is inserted, an air compression pump provided in the optical disc device is operated and the compressed air is used to clean the surface of a laser beam emitting lens.
関連するものに特開昭６０−１２７５４０号がある。A related publication is JP-A-60-127540.
しかしながら上記従来技術では、光ディスク装置内に空
気圧縮ポンプのスペースが必要となり必然的に装置が大
きくなる。又、光ディスクカートリッジを入れる時、空
気圧縮ポンプを動かす為、挿入力が大きくなる。又粘着
性塵埃が付着した時は圧縮空気では飛ばしきれないとの
問題があった。However, in the above-mentioned conventional technology, a space is required for the air compression pump within the optical disc device, which inevitably increases the size of the device. Furthermore, when inserting an optical disc cartridge, the air compression pump is moved, which increases the insertion force. There is also the problem that when sticky dust adheres, it cannot be blown away with compressed air.
本発明の目的はこれらの問題点を解決し、安価なりリー
ニング機構を提供する事にある。An object of the present invention is to solve these problems and provide an inexpensive leaning mechanism.
［課題を解決するための手段〕
上記目的の為、本発明では、光ディスク力−トリッジに
クリーニング機構を設ける事にした。[Means for Solving the Problems] For the above purpose, in the present invention, a cleaning mechanism is provided in the optical disk cartridge.
つまり光ディスクカートリッジにもうけられたクリーニ
ング部材が、光ディスクカートリッジを光ディスク装置
に挿入、排出されるたびにレーザ光出射レンズ表面をク
リーニングする事により達される。That is, this is achieved by a cleaning member provided in the optical disc cartridge cleaning the surface of the laser beam emitting lens each time the optical disc cartridge is inserted into and ejected from the optical disc device.

ッジを光ディスク装置に挿入すると出て来る。このまま
カートリッジを挿入するとレーザ光出射レンズの上をク
リーニング部材が通りすぎる為、レンズ表面がクリーニ
ングされる。A lens cleaning member provided in an optical disc cartridge is normally housed within the cartridge and comes out when the cartridge is inserted into an optical disc device. If the cartridge is inserted in this state, the cleaning member passes over the laser beam emitting lens, thereby cleaning the lens surface.
従ってレンズ表面のゴミがなくなりレーザ出射光量の低
下が無くなる為、読み出し書込みによる誤動作はなくな
る。Therefore, since there is no dust on the lens surface and there is no decrease in the amount of laser emitted light, malfunctions due to reading and writing are eliminated.

にはピニオン１０がありラック６とかみ合っている。An embodiment of the present invention will be described below with reference to FIG. In the figure, an optical disc medium 2 is housed in a case 1. The case 1 has a bed access hole 7 for entering the writing/reading pad 8. Normally, this head access hole 7 is covered with a shutter 3. A rack 6 is provided inside the shutter 3, and a mounting bracket 5 for the brush 4 is provided.
has a pinion 10 that meshes with the rack 6.
光ディスク装置１１には光ディスクカートリッジを装置
内に位置決めする為のローダ１２がもうけられている。The optical disc device 11 is provided with a loader 12 for positioning the optical disc cartridge within the device.

５図に示す。FIG. 3 shows this state in which when the optical disk cartridge is placed in the loader 12, the shutter 3 is opened by the shutter opening/closing arm 13 provided on the loader 12. Then, the mounting bracket 5 rotates in conjunction with the pinion 10 meshed with the rack 6 inside the shutter 3, and the brush 4 pops out from the surface of the case 1. This state is shown in FIG. When the optical disk cartridge is further pushed into the loader 12 in this state, the brush 4 cleans the surface of the laser beam emitting lens 14 on the write/read head 8. This state is shown in FIG.
