- an elastic shock absorber that absorbs impact energy by elastic deformation and a plastic impact that absorbs impact energy by plastic deformation are provided between the disk drive and the case to protect the built-in device from impact. It is disclosed to provide an absorber. An impact below a certain allowable value is absorbed by deformation of the elastic shock absorber, and an impact above a certain allowable value is absorbed by deformation of the plastic shock absorber.
- Patent Documents 3 and 4 a plurality of anti-vibration rubbers are provided on the bottom surface of the head disk assembly between the mounting frame of the head disk assembly, and at least one of these anti-vibration rubbers is used as another anti-vibration rubber. It is disclosed that the holding state of the head disk assembly is stabilized with a different strength.

図1は、本発明の第1の実施の形態における、本発明に係る磁気記憶装置の保持具を内蔵するノート型パソコンを示す斜視図である。ノート型パソコンは、表示部100と入力部200を有する。入力部200には、磁気記憶装置ユニット300が内蔵されている。入力部200は、筐体210、キーボート220及び接触パッド230を備えている。表示部100には、液晶110が設けられている。図2は、図1に示すノート型パソコンを底面から見た斜視図である。筐体210には、リアカバー240、電池カバー250及び磁気記憶装置カバー260が設けられている。各カバーは、図示されないねじ等によって筐体210に接続されている。なお、本発明に係る保持具が搭載される電子機器は、ノート型パソコンに限られるものではなく、音楽端末や情報端末などの電子機器であってもよい。
図10は、本発明の第2の実施形態に係る磁気記憶装置320の保持具の構成を示す平面図である。第1の実施形態においては、対となる対角を保持する保持部材は、同一の緩衝材スポンジゴムによって構成されていたが、第2の実施形態では、四隅を保持する保持部材が、すべて硬度が異なるよう構成されている。磁気記憶装置320の四隅のコーナー部には、左上に緩衝材スポンジゴム340Aが配され、右上に緩衝材スポンジゴム340B、右下に緩衝材スポンジゴム340C、左下に緩衝材スポンジゴム340Dが配されている。ここで、それぞれの保持部材の硬度は、左上から時計回りの順に、340A、340B、340C、340Dと次第に硬度が大きくなるよう構成されている。このように、四隅のコーナー部を保持する保持部材を全て異なる硬度として構成することで、吸収できる振動周波数帯をさらに細かく設定することができる。なお、四隅を保持する保持部材の硬度は、時計回りに変化させる必要はなく、任意に異なる硬度の保持部材を四隅に配しても良い。
図11は、本発明の第3の実施形態に係る磁気記憶装置の保持具の構成例を示す斜視図である。第1の実施形態においては、磁気記憶装置320は、上ケース310及び下ケース330の内側に収容されていたが、第3の実施形態においては、磁気記憶装置320が第1緩衝材スポンジゴム340及び第2緩衝材スポンジゴム350を介して磁気記憶装置320に形成されたリブ211に固定されている。第1緩衝材スポンジゴム340及び第2緩衝材スポンジゴム350は、接着材によってリブ211に固定接続されている。このように、上ケース310及び下ケース330を省略することにより組立部材の数を削減すると共に、第1の実施形態よりも小型化を図ることができる。
図12は、本発明の第4の実施形態に係る磁気記憶装置の保持具の構成例を示す斜視図である。第1~3の実施形態では、四隅のコーナー部に設けられた保持部材は、磁気記憶装置320の厚みよりも厚く形成されていたが、第4の実施形態では、保持部材がL字型に形成され、磁気記憶装置320の厚みと同程度に形成されている。図12に示すように、磁気記憶装置320の四隅には、コーナー部の外周に沿ってL字型の緩衝材スポンジゴムが設置されている。紙面左上及び右下には、同一の硬度の第1緩衝材スポンジゴム341が配されている。また、紙面右上及び左下には、同一の硬度の第2緩衝材スポンジゴム351が配されている。なお、第1緩衝材スポンジゴム341の硬度は、第2緩衝材スポンジゴム351よりも硬い。
図13は、本発明の第5の実施形態に係る磁気記憶装置の保持具の構成例を示す斜視図である。図14は、図13の平面図である。第4の実施形態では、L字型の保持部材が1つの部材として設けられていたが、第5の実施形態では、2つの部材によってそれぞれの第1緩衝材スポンジゴム及び第2緩衝材スポンジゴムが構成されている。具体的には、紙面左上の保持部材は、磁気記憶装置320の短手方向の辺に接する第1緩衝材スポンジゴム342と、長手方向の辺に接する第1緩衝材スポンジゴム343の2つの部材によって構成されている。第1緩衝材スポンジゴム342、343の間には、所定の隙間が介されている。紙面右上の保持部材は、磁気記憶装置320の短手方向の辺に接する第2緩衝材スポンジゴム352と、長手方向の辺に接する第1緩衝材スポンジゴム353の2つの部材によって構成されている。第1緩衝材スポンジゴム352、353の間には、所定の隙間が介されている。このように、磁気記憶装置320の四隅に保持部材が設けられていれば、必ずしも厳密にコーナー部を保持する必要はない。
図15は、第6の実施形態に係る磁気記憶装置の保持具の構成を示す平面図である。第6の実施形態では、一方の対角上に配された第1緩衝材スポンジゴム340と、他方の対角上に設けられた第2緩衝材スポンジゴム354との大きさが異なるよう構成されている。第1緩衝材スポンジゴム340は、第2緩衝材スポンジゴム354に比べて大きい。このように、第1緩衝材スポンジゴム340と第2緩衝材スポンジゴム354の大きさを異ならせることで、衝撃などによって外力が加わったときの第1緩衝材スポンジゴム340及び第2緩衝材スポンジゴム354の変形量を異ならせることができる。これにより、磁気記憶装置320は、緩衝によるエネルギーが磁気記憶装置320の方向への回転に変換することができる。なお、第1緩衝材スポンジゴム340と第2緩衝材スポンジゴム354の硬度は同一であっても異なっていてもよい。
図16A、Bは、本発明の第7の実施形態に係る磁気記憶装置の保持具の構成例を示す平面図である。第7の実施形態においては、一方の対角上にのみ、第1緩衝材スポンジゴム340が配されており、他方の対角上には保持部材が設置されていない。このように、一方の対角上のみに保持部材を設けるように構成しても、一方の対角を保持する保持力の総和と他方の対角を保持する保持力の総和を異ならせることにより、磁気記憶装置に加わった衝撃による荷重を磁気記憶装置の回転に変換することができる。なお、一方の対角上を保持する第1緩衝材スポンジゴム340については、第4、5の実施形態のような形状の緩衝材スポンジゴムを用いることもできる。
図17A、Bは、第8の実施形態に係る磁気記憶装置の保持具の構成を示す斜視図である。第8の実施形態では、第1~第7の実施形態において、保持部材として用いられていた緩衝材スポンジゴムの代わりに、弾性板ばね360が磁気記憶装置の1つの対角線上に設置されている。板バネ360は、図17Aに示すように、紙面左上と紙面右下の磁気記憶装置320のコーナー部に配されている。紙面左上に板バネ360は、所定の衝撃が加わることで、磁気記憶装置320の左上のコーナー部を紙面下方に押し出すよう構成されている。紙面右下の板バネ360は、所定の衝撃が加わることで、磁気記憶装置320の右下のコーナー部を紙面上方に押し出すよう構成されている。
