等１元字的記録再生装置ＩＩＬにおける帯電防止構造に
関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an original disk device, and is used to prevent static electricity in a one-dimensional recording/reproducing device IIL such as a digital disk, "yt," video disk, or original audio disk. It's about structure.
この櫨の元竿的記録再生装置に２いて１元ディスク媒体
の表面のゴミ等はデータエラーの原因となるため、従来
より各種のゴミ除去方法が考えられている。Since dust and the like on the surface of the primary disk medium in this optical recording and reproducing apparatus can cause data errors, various dust removal methods have been devised.
例えばディスク表面のゴミ除去法の１つとして。For example, as a method for removing dust from the disk surface.
ｔ＃願６υ−２８２９３０号に記載の如く必要時のみク
リーナ部材とディスクが接触し、クリーニングする方法
が有る。この方法ではディスクとクリーナ部材の接触が
最低限の時間におさえられている。As described in Application No. 6υ-282930, there is a method in which the cleaner member and the disk come into contact only when necessary to perform cleaning. In this method, contact between the disk and the cleaner member is kept to a minimum amount of time.

生する。However, when a disk is used frequently, static electricity builds up on the original disk due to friction between the original disk and the cleaner member. This accumulated static electricity is discharged to the disk cartridge and the recording/reproducing head located near the disk, and the discharge noise causes malfunction of the device and failure tS.
本発明の目的は、静電気による装置の誤動作。The purpose of the present invention is to prevent device malfunctions caused by static electricity.
故障を防止することにある。The purpose is to prevent breakdowns.
上記目的は、クリーナブラシの材質を導電性部材とし、
かつこのクリーナブラシ全接地させる事にエフ達成され
る。The above purpose is to use a conductive material as the material of the cleaner brush,
And this is achieved by grounding all the cleaner brushes.
この導電性部材全使用したクリーナプランが元ディスク

クにたまらない。The cleaner plan, which uses all of the conductive materials, comes into contact with the original disk and #! Even if static electricity is generated due to rubbing, the static electricity is grounded through the cleaner brush and does not accumulate on the disk.
それによって放電が無くなる為、誤動作が無くなる。This eliminates discharge, which eliminates malfunctions.
以下、本発明の一実施例を第１囚に従って説明する。 Hereinafter, one embodiment of the present invention will be described according to the first example.

接地されている。Eleventhly, the primary disk medium 1 at 8 is fixed to a medium drive spindle 6 by a hub 7 and rotates. RAD2 to record and playback
is placed on carrier 8KfM and moved in the direction of arrow 9. Further, the cleaner brush 5 is driven by the driver 5 and comes into contact with the surface of the disk medium 1. Further, there is a grounding conductive member 4 at the base of the cleaner brush 3, and the cleaner brush 3 is grounded.
従って、クリーナブラシ動作時［はクリーナブラシ５は
ディスク媒体１の表面１ｃ接触すると共に接地用導電部
材４により接地され℃いる。Therefore, when the cleaner brush is in operation, the cleaner brush 5 contacts the surface 1c of the disk medium 1 and is grounded by the grounding conductive member 4.

静電気による誤動作。According to the present invention, since the cleaner brush is made of a conductive material and is grounded, static electricity caused by friction between the cleaner brush and the original disk medium is discharged through the conductive member and accumulated in the original disk medium. Never. Therefore,
Malfunction due to static electricity.
故障の防止することができる。Malfunctions can be prevented.
