以下、図面を参照しながらこの発明の実施の形態に係る電子機器について詳細に説明する。ここでは、電子機器として、ノート型のパーソナルコンピュータ100(以下、単に、ノートPC100と称する)に内蔵されるハードディスク駆動装置1(以下、単に、HDD1と称する)の保持構造について、例示して説明する。   Hereinafter, electronic devices according to embodiments of the present invention will be described in detail with reference to the drawings. Here, as an electronic device, a holding structure of a hard disk drive device 1 (hereinafter simply referred to as HDD 1) built in a notebook personal computer 100 (hereinafter simply referred to as notebook PC 100) will be described as an example. .

図1には、HDD1の保持構造として、HDDホルダー10からHDD1(機能装置)を抜き出した状態の外観斜視図を示してある。HDD1は、ここでは図示を省略するが、ディスク状の磁気記録媒体を支持および回転するスピンドルモータ、磁気ディスクの略半径方向にヘッドを移動可能に懸垂支持したアームを回動させるためのボイスコイルモータ、ヘッドICなどの複数の部品を、略矩形箱形状の筐体1a内に内蔵してユニット化している。以下の説明では、HDD1のここでは図示していない下面をA1と称し、HDD1の上面をB1と称し、4つの側面をそれぞれC1、(D1)、E1、F1と称する。   FIG. 1 is an external perspective view of the HDD 1 holding structure in which the HDD 1 (functional device) is extracted from the HDD holder 10. Although not shown here, the HDD 1 is a spindle motor that supports and rotates a disk-shaped magnetic recording medium, and a voice coil motor that rotates an arm that suspends and supports a head so that the head can move in a substantially radial direction of the magnetic disk. A plurality of components such as a head IC are built in a substantially rectangular box-shaped housing 1a to form a unit. In the following description, the lower surface (not shown) of the HDD 1 is referred to as A1, the upper surface of the HDD 1 is referred to as B1, and the four side surfaces are referred to as C1, (D1), E1, and F1, respectively.

HDDホルダー10は、図2に示す金属板により形成されたホルダー2と、図3に示す金属箔4と、絶縁シート6と、を組み合わせて構成される。   The HDD holder 10 is configured by combining the holder 2 formed of a metal plate shown in FIG. 2, the metal foil 4 shown in FIG. 3, and an insulating sheet 6.

ホルダー2は、図2に示すように、薄い金属板の複数個所にネジ孔2a、2bを形成して複数個所で折り曲げることにより形成されている。ホルダー2は、HDD1の下面A1に対向する矩形の底板部A2、およびHDD1の3つの側面C1、D1、E1にそれぞれ対向する3枚の側板部C2、D2、E2を一体に有する。言い換えると、HDD1の上面B1に対向する部分、およびHDD1のコネクタ1bが突出した側面F1に対向する部分は、開放している。   As shown in FIG. 2, the holder 2 is formed by forming screw holes 2a and 2b at a plurality of locations on a thin metal plate and bending them at a plurality of locations. The holder 2 integrally includes a rectangular bottom plate portion A2 facing the lower surface A1 of the HDD 1 and three side plate portions C2, D2, E2 facing the three side surfaces C1, D1, E1 of the HDD 1, respectively. In other words, the portion facing the upper surface B1 of the HDD 1 and the portion facing the side surface F1 from which the connector 1b of the HDD 1 protrudes are open.

HDD1のコネクタ1bから離間した側の側板部E2は、HDDホルダー2をノートPC100の本体内所定位置に固設するためのネジ孔2aを形成した突片2eを有する。また、他の2枚の側板部C2、D2には、HDDホルダー10内に挿入配置したHDD1をネジ3(図1参照)により固定するためのネジ孔2bがそれぞれ形成されている。尚、HDD1の対応する2つの側面C1、D1にも、ネジ孔1cが形成されている。   The side plate E2 on the side away from the connector 1b of the HDD 1 has a projecting piece 2e formed with a screw hole 2a for fixing the HDD holder 2 at a predetermined position in the main body of the notebook PC 100. The other two side plate portions C2 and D2 are respectively formed with screw holes 2b for fixing the HDD 1 inserted and arranged in the HDD holder 10 with screws 3 (see FIG. 1). Note that screw holes 1c are also formed in two corresponding side surfaces C1 and D1 of the HDD 1.

金属箔4は、図3に示すように、矩形板状のプラスティックにより形成された絶縁シート6を介してHHD1の上面B1に対向する矩形の主部分B3、およびホルダー2の3つの側板部C2、D2、E2に貼り付けるための複数の延出部分C3、D3、E3を有する。絶縁シート6および主部分B3の形状は、HDD1やホルダー2の形状に合わせられている。本実施の形態では、アルミニウム箔の1面に接着剤を塗布したシート状の金属シールを用意して、金属箔とシール層を同時に図示の形状に切り抜いて金属箔4を形成した。   As shown in FIG. 3, the metal foil 4 includes a rectangular main portion B3 facing the upper surface B1 of the HHD 1 through an insulating sheet 6 formed of a rectangular plate-shaped plastic, and three side plate portions C2 of the holder 2. A plurality of extending portions C3, D3, and E3 for attaching to D2 and E2 are provided. The shapes of the insulating sheet 6 and the main portion B3 are matched with the shapes of the HDD 1 and the holder 2. In the present embodiment, a sheet-like metal seal in which an adhesive is applied to one surface of an aluminum foil is prepared, and the metal foil 4 and the sealing layer are cut out into the illustrated shape at the same time to form the metal foil 4.

そして、この金属箔4をホルダー2に取り付ける場合、金属箔4の主部分B3に絶縁シート6を貼り付け、絶縁シート6が下を向くようにホルダー2の開放した上面を塞ぎ、複数の延出部分C3、D3、E3を折り曲げてホルダー2の対応する側板部C2、D2、E2に貼り付ける。尚、金属箔4とホルダー2が電気的に導通する必要があるため、少なくとも延出部分を貼り付ける接着剤は、導電性を有する必要がある。   And when attaching this metal foil 4 to the holder 2, the insulating sheet 6 is stuck on the main part B3 of the metal foil 4, the open upper surface of the holder 2 is closed so that the insulating sheet 6 faces down, and a plurality of extensions are provided. The portions C3, D3, and E3 are bent and attached to the corresponding side plate portions C2, D2, and E2 of the holder 2. In addition, since it is necessary for the metal foil 4 and the holder 2 to be electrically connected, at least the adhesive for attaching the extending portion needs to have conductivity.

また、金属箔4および絶縁シート6には、HHDホルダー10を軽量化する目的で、円形の孔4a、6aが形成されている。孔4a、6aの形状および大きさは、任意に設定可能であるが、軽量化のため孔を大きくし過ぎるとHDD1から発生する電磁波のシールド効果が低下するため、適当な大きさに設定する必要がある。また、プラスティックからなる絶縁シート6は比較的軽量のため、必ずしも孔6aを設ける必要はない。   In addition, circular holes 4 a and 6 a are formed in the metal foil 4 and the insulating sheet 6 for the purpose of reducing the weight of the HHD holder 10. The shape and size of the holes 4a and 6a can be arbitrarily set. However, if the hole is made too large for weight reduction, the shielding effect of the electromagnetic wave generated from the HDD 1 is lowered, so it is necessary to set it to an appropriate size. There is. Further, since the insulating sheet 6 made of plastic is relatively light, it is not always necessary to provide the hole 6a.

上記のように構成されたHDDホルダー10にHDD1を取り付ける場合、HDDホルダー10の開口部10aからHDD1を挿入し、HDDホルダー10の外側から4本のネジ3をネジ孔2b、1cに螺合する。これにより、HDD1がHDDホルダー10に保持固定される。   When the HDD 1 is attached to the HDD holder 10 configured as described above, the HDD 1 is inserted from the opening 10a of the HDD holder 10, and the four screws 3 from the outside of the HDD holder 10 are screwed into the screw holes 2b and 1c. . As a result, the HDD 1 is held and fixed to the HDD holder 10.

このようにHDD1を保持固定したHDDホルダー10は、図4に示す姿勢でノートPC100内に収容配置される。すなわち、ノートPC100の本体裏面側にホルダー2が位置し、本体表面側に金属箔4が位置するように、HDDホルダー10がPC本体内に収容配置される。 The HDD holder 10 that holds and fixes the HDD 1 in this manner is accommodated in the notebook PC 100 in the posture shown in FIG. That is, the HDD holder 10 is accommodated in the PC main body so that the holder 2 is located on the back side of the main body of the notebook PC 100 and the metal foil 4 is located on the front surface side of the main body.

図5乃至図7には、ノートPC100をその裏面側から見た斜視図を示してある。図5は、HDDホルダー10を収容する収容部101のカバー102を取り除いた状態を示してあり、図6には、収容部101内にHDDホルダー10を収容配置した状態を示してあり、図7には、収容部101のカバー102を取り付けた状態を示してある。   5 to 7 are perspective views of the notebook PC 100 as viewed from the back side. FIG. 5 shows a state in which the cover 102 of the housing part 101 that houses the HDD holder 10 is removed, and FIG. 6 shows a state in which the HDD holder 10 is housed and disposed in the housing part 101. In the figure, a state in which the cover 102 of the accommodating portion 101 is attached is shown.

上述した姿勢でHDDホルダー10をPC本体内に収容配置することにより、ノートPC100の裏面側から不所望な外圧が作用した場合、剛性の高い金属板により形成されたホルダー2により外圧からHDD1を保護することができる。   When the HDD holder 10 is accommodated and arranged in the PC body in the above-described manner, when an undesired external pressure is applied from the back side of the notebook PC 100, the HDD 1 is protected from the external pressure by the holder 2 formed of a highly rigid metal plate. can do.

以上のように、本発明によると、HDDホルダー10の一部を金属箔4により形成しているため、HDDホルダー10の全ての部分を金属板により形成する場合と比較して、軽くでき、HDDホルダー10を組み込むノートPCの重量も軽くできる。その上、HDDホルダー10の金属箔4によって、HDD1から発生する電磁波を十分にシールドでき、電磁波のシールド効果を低下させることがない。   As described above, according to the present invention, since a part of the HDD holder 10 is formed of the metal foil 4, the HDD holder 10 can be made lighter than the case where all the parts of the HDD holder 10 are formed of the metal plate. The weight of the notebook PC incorporating the holder 10 can be reduced. In addition, the metal foil 4 of the HDD holder 10 can sufficiently shield the electromagnetic waves generated from the HDD 1 and does not lower the electromagnetic wave shielding effect.

また、本発明のHDDホルダー10は、絶縁シート6を貼り合わせた金属箔4をホルダー2の側板部に貼り合わせるだけの簡単な工程で製造でき、従来のように、板金をスポット溶接やカシメ固定などの方法によって接合する必要がなく、容易に製造でき、製造コストを低減できる。   Further, the HDD holder 10 of the present invention can be manufactured by a simple process of simply bonding the metal foil 4 bonded with the insulating sheet 6 to the side plate portion of the holder 2, and the sheet metal can be fixed by spot welding or caulking as in the past. Therefore, it is not necessary to join by a method such as the above, it can be easily manufactured, and the manufacturing cost can be reduced.

なお、この発明は、上述した実施の形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上述した実施の形態に開示されている複数の構成要素の適宜な組み合わせにより種々の発明を形成できる。例えば、上述した実施の形態に示される全構成要素から幾つかの構成要素を削除しても良い。   Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above.

例えば、上述した実施の形態では、金属箔4としてアルミニウム箔を用いた場合について説明したが、これに限らず、銅箔など電磁波のシールド特性が良好な他の金属箔を用いても良い。   For example, in the above-described embodiment, the case where an aluminum foil is used as the metal foil 4 has been described. However, the present invention is not limited to this, and other metal foils having good electromagnetic wave shielding characteristics such as a copper foil may be used.

また、上述した実施の形態では、本発明をHDD1の保持構造に適用した場合について説明したが、これに限らず、光ディスク装置などの他の機能装置の保持構造に本発明を適用することもできる。   Further, in the above-described embodiment, the case where the present invention is applied to the holding structure of the HDD 1 has been described. .

さらに、上述した実施の形態では、ホルダー2の上面を金属箔4によってカバーする構造としたが、これに限らず、例えば、HDD1のコネクタ1bから離間した側のホルダー2の側板部E2を無くして、代りに、ホルダー2の上面および1つの側面を金属箔によってカバーする構造としても良い。いずれにしても、ホルダー2がHDD1の一部をカバーし、ホルダー2がカバーしていないHDD1の筐体表面を金属箔4によって部分的にカバーするように、ホルダー2および金属箔4の形状を設計すれば良い。   Furthermore, in the above-described embodiment, the upper surface of the holder 2 is covered with the metal foil 4. However, the present invention is not limited to this. For example, the side plate portion E2 of the holder 2 on the side separated from the connector 1b of the HDD 1 is eliminated. Instead, the upper surface and one side surface of the holder 2 may be covered with a metal foil. In any case, the shape of the holder 2 and the metal foil 4 is such that the holder 2 covers a part of the HDD 1 and the housing surface of the HDD 1 that is not covered by the holder 2 is partially covered by the metal foil 4. Just design.
