本考案はフレキシブルディスクドライブ等の磁気記録装置に関する。 The present invention relates to a magnetic recording device such as a flexible disk drive.

磁気記録装置への磁気記録媒体の出し入れなどの操作時に人体などから静電気 が放電する場合があり、それから磁気記録装置を保護する対策の従来技術として 、公開実用新案公報平２−１３２３４８や平２−１２８２９８に記載されたもの のように何らかの保護導電体を設ける方法等があった。 Static electricity may be discharged from the human body when the magnetic recording medium is put into or taken out of the magnetic recording device, and as a conventional technique for protecting the magnetic recording device from that, there are publicly available utility model publications 2-132348 and 2-. There has been a method of providing some kind of protective conductor such as the one described in 128298.
【０００３】 図３はモデル化した従来技術の斜視図である。非導電性ベゼル５と磁気記録装 置本体６の間に導電性プレート１が設けられる。非導電性ベゼル５の開口部より 進入する静電気は磁気記録装置本体６より非導電性ベゼル５の近くに設置された 導電性プレート１に放電される。このとき、導電性プレート１が電気的に浮いて いるとすると導電性プレート１へ移動した電荷はより近い導電体である磁気記録 装置本体６に２次放電するため、導電性プレート１は磁気記録装置本体６への放 電防止の機能を果たさない。そのため、導電性プレート１は磁気記録装置本体６ もしくは磁気記録装置を内蔵するシステムのフレームと電気的接続をとることで 、磁気記録装置本体６へ直接静電気が放電することを防ぎ、それにより磁気記録 装置本体６内の回路ユニットへの２次放電を防ぎ、回路ユニットの静電破壊を防 ぐことができた。FIG. 3 is a perspective view of a modeled prior art. The conductive plate 1 is provided between the non-conductive bezel 5 and the magnetic recording device body 6. Static electricity entering through the opening of the non-conductive bezel 5 is discharged from the magnetic recording apparatus main body 6 to the conductive plate 1 installed near the non-conductive bezel 5. At this time, assuming that the conductive plate 1 is electrically floating, the charges moved to the conductive plate 1 are secondarily discharged to the magnetic recording apparatus main body 6 which is a closer conductor, so that the conductive plate 1 is magnetically recorded. It does not function to prevent discharge of electricity to the device body 6. Therefore, the conductive plate 1 is electrically connected to the magnetic recording device main body 6 or the frame of the system incorporating the magnetic recording device to prevent static electricity from being directly discharged to the magnetic recording device main body 6 and thereby the magnetic recording. Secondary discharge to the circuit unit in the device body 6 was prevented, and electrostatic damage to the circuit unit could be prevented.
【０００４】[0004]
但し、導電性プレート１に放電した電荷はシステムのフレームグランドに流れ 込むがその経路からの非常に強い輻射ノイズによって磁気記録装置が誤動作を起 こす場合がある。磁気記録装置本体６とシステムのフレームは金属性ネジでネジ 止めされるなどして、磁気記録装置本体６の金属部分とシステムのフレームグラ ンドは電気的に接続されており、また導電性プレート１はシステムのフレームも しくは磁気記録装置本体６と電気的に接続されているため、導電性プレート１に 放電した電荷が磁気記録装置本体６を介してフレームグランドに流れ込む場合が ある。このときの電荷の流れ方を図４に示す。この場合特に誤動作を起こし易い 。そのため従来技術では磁気記録装置の誤動作防止について十分な効果が得られ ない。またこのような誤動作モードはシステムのフレームグランド構造によって も影響度が変わり、システムごとに何らかの対策を取る必要があった。 However, although the electric charge discharged to the conductive plate 1 flows into the frame ground of the system, the magnetic recording device may malfunction due to extremely strong radiation noise from the path. The metal part of the magnetic recording device main body 6 and the frame frame of the system are electrically connected by, for example, screwing the magnetic recording device main body 6 and the system frame with a metal screw. Since it is electrically connected to the frame of the system or the main body 6 of the magnetic recording device, the electric charge discharged to the conductive plate 1 may flow into the frame ground through the main body 6 of the magnetic recording device. FIG. 4 shows how electric charges flow at this time. In this case, malfunction is particularly likely to occur. Therefore, the related art cannot obtain a sufficient effect for preventing malfunction of the magnetic recording device. In addition, the degree of influence of such a malfunction mode depends on the frame ground structure of the system, and it is necessary to take some measures for each system.

上記課題を解決するため本考案の磁気記録装置は、磁気記録装置の前面に、磁 気記録装置と絶縁された導電性プレートを設け、かつその導電性プレートにシス テムのフレームグランドへ直結された配線と接続するための端子を設けたことを 特徴とする。 In order to solve the above-mentioned problems, the magnetic recording apparatus of the present invention is provided with a conductive plate insulated from the magnetic recording apparatus on the front surface of the magnetic recording apparatus, and the conductive plate is directly connected to the frame ground of the system. It is characterized by the provision of terminals for connecting to wiring.

以下本考案に付いて一実施例に基づき詳細な説明を行う。 The present invention will be described below in detail based on an embodiment.
【０００７】 図１は本考案の構成を示す斜視図である。磁気記録装置本体６と、操作面であ る正面に設けられる非導電性ベゼル５の間に導電性プレート１を設ける。導電性 プレート１は、非導電性ベゼル５の媒体挿入口や媒体排出ボタン等の開口部に合 わせた穴が開けられており、非導電性ベゼル５の開口部から進入する静電気を磁 気記録装置本体６に達する前に導電性プレート１に放電させる目的を持つ。また 導電性プレート１は非導電性ベゼル５に固定し磁気記録装置本体６とは絶縁状態 とする。FIG. 1 is a perspective view showing the structure of the present invention. The conductive plate 1 is provided between the magnetic recording device main body 6 and the non-conductive bezel 5 provided on the front surface which is the operation surface. The conductive plate 1 is provided with holes corresponding to the openings of the non-conductive bezel 5 such as the medium insertion port and the medium ejection button, and the static electricity entering from the opening of the non-conductive bezel 5 is magnetically recorded. The purpose is to discharge the conductive plate 1 before it reaches the device body 6. Further, the conductive plate 1 is fixed to the non-conductive bezel 5 and is insulated from the magnetic recording device main body 6.
【０００８】 導電性プレート１に、磁気記録装置を内蔵するシステムのフレームグランドと 電気的接続をとるために端子２を設ける。磁気記録装置を内蔵するシステム側で は、フレームグランドへ直結された配線４と、配線４に接続された配線側端子３ を用意し、端子２と配線側端子３を結合することにより、導電性プレート１とシ ステムのフレームグランドを電気的に直接接続することができる。A terminal 2 is provided on the conductive plate 1 for electrical connection with the frame ground of a system containing a magnetic recording device. On the system side incorporating the magnetic recording device, the wiring 4 directly connected to the frame ground and the wiring side terminal 3 connected to the wiring 4 are prepared, and by connecting the terminal 2 and the wiring side terminal 3, the conductivity The plate 1 and the frame ground of the system can be directly electrically connected.
【０００９】 磁気記録装置への磁気記録媒体の出し入れ等の操作時に操作する人体が帯電し ている場合静電気が放電される。図１の様な構成の磁気記録装置においては、そ の静電気は非導電性ベゼル５の開口部から進入するが、静電気はより近い金属部 分へ放電されるので、磁気記録装置本体６に比べ非導電性ベゼル５との距離が近 い導電性プレート１に放電されることになる。導電性プレート１へ放電された静 電気の電荷は端子２、配線側端子３、配線４を介して磁気記録装置を内蔵するシ ステムのフレームグランドに流れ込む。このとき導電性プレート１をはじめ、端 子２、配線側端子３、配線４が磁気記録装置本体６と絶縁されているので、静電 気は磁気記録装置本体６を流れることがない。このときの電荷の流れ方を図２に 示す。そのため従来技術の磁気記録装置本体を静電気が流れることによる磁気記 録装置の誤動作の問題を解決することができる。また、磁気記録装置とそれを内 蔵するシステムの取付方法に関わらない方法でそれを実現することが可能となる 。Static electricity is discharged when the human body to be operated is charged when the magnetic recording medium is taken in and out of the magnetic recording device. In the magnetic recording device having the configuration as shown in FIG. 1, the static electricity enters from the opening of the non-conductive bezel 5, but the static electricity is discharged to a closer metal part, so that the magnetic recording device main body 6 has It will be discharged to the conductive plate 1 which is close to the non-conductive bezel 5. The electrostatic charge discharged to the conductive plate 1 flows into the frame ground of the system incorporating the magnetic recording device through the terminal 2, the wiring side terminal 3, and the wiring 4. At this time, since the conductive plate 1, the terminal 2, the wiring side terminal 3, and the wiring 4 are insulated from the magnetic recording device main body 6, electrostatic air does not flow through the magnetic recording device main body 6. Figure 2 shows how the charge flows at this time. Therefore, it is possible to solve the problem of malfunction of the magnetic recording apparatus due to static electricity flowing through the magnetic recording apparatus main body of the related art. In addition, it is possible to realize it by a method that is independent of the method of mounting the magnetic recording device and the system that houses it.
