連結部を介して第１の本体部から第２の本体部にかけて延設されるシート状の基板を有し、伝熱部材を、基板の表面に密着されて基板を保護する保護シートとして構成し、この保護シートを回動軸の周面に捲着して延設することもできる。
伝熱部材を、その一端部がディスク装置の表面を覆うように設け、他端部が回動軸の周面に捲着されるように設けることもできる。
回動軸の端部が外部に露出して設けられるとともに、この端部を貫通して回動軸の内部に通気孔が設けられることが、放熱性を高める上で好ましい。
携帯通信端末に撮像素子を収容する場合には、第２の本体部に収容することが好ましい。 The present invention includes a first main body that accommodates various components including a disk device for storing information, a second main body that accommodates other various components, a first main body, and a second main body. A mobile communication terminal having a connecting portion that is rotatably connected via a rotating shaft, wherein the heat from the disk device is transferred to the connecting portion by heat conduction and radiated to the outside. A heat transfer member interposed between the connecting portion and the connecting portion is provided.
The heat transfer member may be formed by a holding member that holds the disk device, and one end portion of the holding member may be extended to the connecting portion and provided in contact with the rotating shaft. Moreover, the contact part which the one end part of a holding member contacts and separates according to the rotation amount of the 2nd main body part with respect to a 1st main body part can also be provided in the surrounding surface of a rotating shaft.
It has a sheet-like substrate extending from the first main body to the second main body via the connecting portion, and the heat transfer member is configured as a protective sheet that is in close contact with the surface of the substrate and protects the substrate.

The heat transfer member may be provided so that one end thereof covers the surface of the disk device and the other end is attached to the peripheral surface of the rotating shaft.
In order to improve heat dissipation, it is preferable that an end portion of the rotating shaft is provided to be exposed to the outside and a vent hole is provided inside the rotating shaft through the end portion.
When the image sensor is accommodated in the mobile communication terminal, it is preferably accommodated in the second main body.

本発明によれば、携帯通信端末に内蔵された情報記憶用のディスク装置の温度上昇を効果的に抑えることができる。   ADVANTAGE OF THE INVENTION According to this invention, the temperature rise of the disk apparatus for information storage built in the portable communication terminal can be suppressed effectively.

−第１の実施の形態−
以下、図１を参照して本発明による携帯通信端末を携帯電話に適用した第１の実施の形態について説明する。
図１（ａ）は、第１の実施の形態に係る携帯電話の外観形状を示す斜視図であり、図１（ｂ）は、この携帯電話の内部構造を示す斜視図、図１（ｃ）は図１（ｂ）のｃ−ｃ線断面図である。以下では、図示のように携帯電話の上下左右方向を定義し、この定義にしたがって各部の配置を説明する。 -First embodiment-
Hereinafter, a first embodiment in which a mobile communication terminal according to the present invention is applied to a mobile phone will be described with reference to FIG.
FIG. 1A is a perspective view showing an external shape of the mobile phone according to the first embodiment, and FIG. 1B is a perspective view showing an internal structure of the mobile phone, and FIG. FIG. 2 is a cross-sectional view taken along the line cc of FIG. In the following, the vertical and horizontal directions of the mobile phone are defined as shown, and the arrangement of each part will be described according to this definition.

本実施の形態に係る携帯電話は、下本体１および上本体２を回動軸３を介して互いに回動可能に連結する折り畳み式の携帯電話である。図１は携帯電話を開いた状態を示しており、この状態では下本体１の内表面１１と上本体２の内表面２１がそれぞれ露出している。なお、携帯電話を閉じた状態では、内表面１１，２１同士が互いに対向し、外部から隠蔽される。   The mobile phone according to the present embodiment is a foldable mobile phone in which a lower main body 1 and an upper main body 2 are rotatably connected to each other via a rotary shaft 3. FIG. 1 shows a state in which the cellular phone is opened. In this state, the inner surface 11 of the lower main body 1 and the inner surface 21 of the upper main body 2 are exposed. When the cellular phone is closed, the inner surfaces 11 and 21 face each other and are hidden from the outside.

図１（ａ）に示すように樹脂製のボディ１０によって覆われた下本体１の内表面１１には電話番号等の各種指令を入力する複数の操作ボタン１２が配設され、樹脂製のボディ２０によって覆われた上本体２の内表面２１にはＬＣＤ２２が配設されている。下本体１の上端部と上本体２の下端部はそれぞれ凹凸状に形成され、これらは互いに嵌合している。すなわち下本体１の凸部１０ａと１０ｂの間の凹部および凸部１０ｂと１０ｃの間の凹部に、それぞれ上本体２の凸部２０ａおよび２０ｂが嵌合している。   As shown in FIG. 1A, a plurality of operation buttons 12 for inputting various commands such as telephone numbers are disposed on the inner surface 11 of the lower main body 1 covered with a resin body 10, and the resin body An LCD 22 is disposed on the inner surface 21 of the upper main body 2 covered with 20. The upper end portion of the lower main body 1 and the lower end portion of the upper main body 2 are formed in an uneven shape, and these are fitted to each other. That is, the convex portions 20a and 20b of the upper main body 2 are fitted in the concave portion between the convex portions 10a and 10b of the lower main body 1 and the concave portion between the convex portions 10b and 10c, respectively.

回動軸３は凸部１０ａ〜１０ｃ，２０ａ，２０ｂを左右方向に貫通し、回動軸３の左右端面は外部に露出している。回動軸３は熱伝導性のよい材質（例えばアルミ）によって形成され、回動軸３に伝えられた熱は左右端面から効率よく放熱できるようになっている。なお、凸部１０ａ〜１０ｃ，２０ａ，２０ｂと回動軸３がヒンジ部ＨＧを構成する。   The rotating shaft 3 penetrates the convex portions 10a to 10c, 20a, and 20b in the left-right direction, and the left and right end surfaces of the rotating shaft 3 are exposed to the outside. The rotation shaft 3 is made of a material having good thermal conductivity (for example, aluminum), and the heat transmitted to the rotation shaft 3 can be efficiently radiated from the left and right end surfaces. In addition, convex part 10a-10c, 20a, 20b and the rotating shaft 3 comprise the hinge part HG.

図１（ｂ）に示すよう下本体１のボディ１０の内側には下基板１３が配設され、上本体２のボディ２０の内側には上基板２３が配設されている。下基板１３の上部にはコネクタ１４を介してシート状のフレキシブル基板３０の一端が接続されている。フレキシブル基板３０はヒンジ部ＨＧ（凸部２０ａ，１０ｂ）を貫通し、その他端はコネクタ２４を介して上基板２３の下部に接続されている。   As shown in FIG. 1B, a lower substrate 13 is disposed inside the body 10 of the lower body 1, and an upper substrate 23 is disposed inside the body 20 of the upper body 2. One end of a sheet-like flexible substrate 30 is connected to the upper portion of the lower substrate 13 via a connector 14. The flexible substrate 30 passes through the hinge portion HG (projections 20 a and 10 b), and the other end is connected to the lower portion of the upper substrate 23 via the connector 24.

図１（ｄ）に示すようにフレキシブル基板３０の両表面にはアルミ箔などの保護シート３１が密着され、フレキシブル基板３０の表面は保護シート３１により覆われ、保護されている。保護シート３１は熱伝導性のよい材質によって形成されるのであれば、アルミ箔以外であってもよい。フレキシブル基板３０はヒンジ部ＨＧを貫通する際に回動軸３の外周面に１回転巻き付けられ、保護シート３１が回動軸３の周面に密着されている。   As shown in FIG. 1 (d), protective sheets 31 such as aluminum foil are in close contact with both surfaces of the flexible substrate 30, and the surface of the flexible substrate 30 is covered and protected by the protective sheet 31. The protective sheet 31 may be other than aluminum foil as long as it is made of a material having good thermal conductivity. The flexible substrate 30 is wound once around the outer peripheral surface of the rotating shaft 3 when penetrating the hinge portion HG, and the protective sheet 31 is in close contact with the peripheral surface of the rotating shaft 3.

下基板１３の表面には図１（ｃ）に示すように小型（例えば１インチ程度）でかつ大容量のＨＤＤ４（Hard Disk Drive ）が実装されている。ＨＤＤ４は、ＨＤＤケース内に回転可能にハードディスクを収容し、このケース内で高速回転させたハードディスクに磁気ヘッドを近づけて、ハードディスクからの情報を読み書きするように構成した記憶装置であり、ハードディスクには例えばデジタル映像や音楽、ゲームプログラム等の各種情報を記憶することができる。ＨＤＤケースの両面には衝撃吸収用の緩衝材５が当接し、この緩衝材５を介して下基板１３に保護カバー６が取り付けられ、保護カバー６によりＨＤＤ４が押圧保持されている。なお、本体１，２にはマイク，スピーカ，バッテリ，アンテナ等も配設されるが、これらの図示は省略する。   A small (for example, about 1 inch) and large capacity HDD 4 (Hard Disk Drive) is mounted on the surface of the lower substrate 13 as shown in FIG. The HDD 4 is a storage device configured to house a hard disk rotatably in an HDD case, and to read and write information from the hard disk by bringing a magnetic head close to the hard disk rotated at high speed in the case. For example, various types of information such as digital video, music, and game programs can be stored. The shock absorbing shock absorbing material 5 abuts on both surfaces of the HDD case, and the protective cover 6 is attached to the lower substrate 13 via the shock absorbing material 5, and the HDD 4 is pressed and held by the protective cover 6. The main bodies 1 and 2 are also provided with microphones, speakers, batteries, antennas, etc., but these are not shown.

第１の実施の形態に係る携帯通信端末の主要な動作を説明する。
例えば携帯電話を用いて映像や音楽等を視聴するときは、ハードディスクからの情報の読み書きを行うため、ＨＤＤ４が作動して発熱する。ＨＤＤ４からの熱は緩衝材５を介して下基板１３に伝熱され、さらにフレキシブル基板３０の表面の保護シート３１を介して熱伝導により回動軸３に伝熱される。回動軸３の左右端部は外部に露出しているため最も低温であり、回動軸３に伝えられた熱はこの端部から外部に放熱される。このようにＨＤＤ４からの熱を保護シート３１を介して回動軸３に伝熱し、回動軸３から外部に放熱することでＨＤＤ４の温度上昇を抑えることができ、ＨＤＤ４からの熱により下本体１のボディ１０やその内部に収容された電子部品等が高温となることを防ぐことができる。この場合、ＨＤＤ４から保護シート３１への伝熱性を高めるためには、緩衝材５や下基板１３を熱伝導率の高い材質により形成することが好ましい。 Main operations of the mobile communication terminal according to the first embodiment will be described.
For example, when viewing video or music using a mobile phone, the HDD 4 operates to generate heat because information is read and written from the hard disk. Heat from the HDD 4 is transferred to the lower substrate 13 through the buffer material 5, and further transferred to the rotating shaft 3 by heat conduction through the protective sheet 31 on the surface of the flexible substrate 30. Since the left and right ends of the rotating shaft 3 are exposed to the outside, the temperature is lowest, and the heat transmitted to the rotating shaft 3 is radiated to the outside from this end. Thus, the heat from the HDD 4 is transferred to the rotating shaft 3 through the protective sheet 31 and is radiated to the outside from the rotating shaft 3, so that the temperature rise of the HDD 4 can be suppressed. It is possible to prevent the body 10 of 1 and the electronic components accommodated therein from becoming hot. In this case, in order to improve the heat transfer from the HDD 4 to the protective sheet 31, it is preferable to form the buffer material 5 and the lower substrate 13 with a material having high thermal conductivity.

以上の第１の実施の形態によれば以下のような作用効果を奏することができる。
（１）フレキシブル基板３０の表面を保護シート３１により保護し、この保護シート３１を介してフレキシブル基板３０を回動軸３に巻き付けるようにした。これによりＨＤＤ４からの熱が保護シート３１を介して回動軸３に伝熱され、回動軸３から放熱することができる。その結果、ＨＤＤ４を熱源としたボディ１０の温度上昇を防ぐことができ、電話の操作者に不快感を与えることを防止できる。また、本体１内の電子部品の温度上昇を防ぐことができ、携帯電話の寿命や性能に対して悪影響を及ぼすことを阻止できる。
（２）フレキシブル基板３０の表面の保護シート３１を回動軸３への伝熱部材として用いるため、伝熱部材を別途設ける必要がなく、部品点数が増加することはない。
（３）フレキシブル基板３０は上基板２３にも接続されているため、ＬＣＤ２２等、上本体２側からの熱も回動軸３を介して外部に放熱できる。 According to the above 1st Embodiment, there can exist the following effects.
(1) The surface of the flexible substrate 30 is protected by the protective sheet 31, and the flexible substrate 30 is wound around the rotating shaft 3 via the protective sheet 31. As a result, heat from the HDD 4 is transferred to the rotating shaft 3 via the protective sheet 31 and can be radiated from the rotating shaft 3. As a result, the temperature rise of the body 10 using the HDD 4 as a heat source can be prevented, and discomfort to the telephone operator can be prevented. Moreover, the temperature rise of the electronic components in the main body 1 can be prevented, and adverse effects on the life and performance of the mobile phone can be prevented.
(2) Since the protective sheet 31 on the surface of the flexible substrate 30 is used as a heat transfer member to the rotating shaft 3, there is no need to separately provide a heat transfer member, and the number of components does not increase.
(3) Since the flexible substrate 30 is also connected to the upper substrate 23, heat from the upper body 2 side such as the LCD 22 can also be radiated to the outside via the rotating shaft 3.

−第２の実施の形態−
図２を参照して本発明による第２の実施の形態について説明する。
第１の実施の形態では、ＨＤＤ４からの熱を下基板１３と保護シート３１を介して回動軸３に伝熱するようにしたが、下基板１３を介さずに回動軸３に伝熱するようにしてもよく、これを実現するのが第２の実施の形態である。 -Second Embodiment-
A second embodiment according to the present invention will be described with reference to FIG.
In the first embodiment, heat from the HDD 4 is transferred to the rotating shaft 3 via the lower substrate 13 and the protective sheet 31, but heat is transferred to the rotating shaft 3 without passing through the lower substrate 13. This may be done, and this is realized in the second embodiment.

図２（ａ）は、第２の実施の形態に係る携帯電話の内部構造を示す斜視図であり、図２（ｂ）は図２（ａ）のｂ部拡大図である。なお、図１と同一の箇所には同一の符号を付し、以下ではその相違点を主に説明する。   FIG. 2A is a perspective view showing the internal structure of the mobile phone according to the second embodiment, and FIG. 2B is an enlarged view of a portion b in FIG. 2A. In addition, the same code | symbol is attached | subjected to the location same as FIG. 1, and the difference is mainly demonstrated below.

図２（ａ），（ｂ）に示すようにフレキシブル基板３０の表面の保護シート３１は、コネクタ１４と回動軸３の間からＨＤＤ側に延設され、その端部は保持カバー６の外表面に接着されている。これによりＨＤＤ４からの熱は緩衝材５，保持カバー６，保護シート３１を介して熱伝導により回動軸３に伝熱される。したがって、下基板１３を介さずにＨＤＤ４からの熱が回動軸３に伝熱されるので、ＨＤＤ４の温度上昇を効果的に抑制することができる。   As shown in FIGS. 2A and 2B, the protective sheet 31 on the surface of the flexible substrate 30 extends to the HDD side from between the connector 14 and the rotating shaft 3, and its end is outside the holding cover 6. Bonded to the surface. As a result, heat from the HDD 4 is transferred to the rotating shaft 3 by heat conduction through the buffer material 5, the holding cover 6, and the protective sheet 31. Therefore, the heat from the HDD 4 is transferred to the rotating shaft 3 without passing through the lower substrate 13, so that the temperature increase of the HDD 4 can be effectively suppressed.

なお、図２（ａ），（ｂ）では保護シート３１の一端部を保持カバー６の外表面に接着するようにしたが、図２（ｃ）に示すように保持カバー６の内表面に接着するようにしてもよい。   2A and 2B, one end of the protective sheet 31 is bonded to the outer surface of the holding cover 6, but it is bonded to the inner surface of the holding cover 6 as shown in FIG. You may make it do.

−第３の実施の形態−
図３を参照して本発明による第３の実施の形態について説明する。
第１の実施の形態では、フレキシブル基板３０の表面の保護シート３１を介してＨＤＤ４からの熱を回動軸３に伝熱するようにしたが、第３の実施の形態ではＨＤＤ４から回動軸３への伝熱性を高めるため、さらに伝熱部材（伝熱シート７）を別途設ける。 -Third embodiment-
A third embodiment of the present invention will be described with reference to FIG.
In the first embodiment, heat from the HDD 4 is transferred to the rotating shaft 3 via the protective sheet 31 on the surface of the flexible substrate 30. However, in the third embodiment, the rotating shaft is transferred from the HDD 4 to the rotating shaft. In order to improve the heat transfer property to 3, a heat transfer member (heat transfer sheet 7) is additionally provided.

図３（ａ）は、第３の実施の形態に係る携帯電話の内部構造を示す斜視図であり、図３（ｂ）は図３（ａ）のｂ部拡大図である。なお、図１と同一の箇所には同一の符号を付し、以下ではその相違点を主に説明する。   FIG. 3A is a perspective view showing an internal structure of a mobile phone according to the third embodiment, and FIG. 3B is an enlarged view of a portion b in FIG. In addition, the same code | symbol is attached | subjected to the location same as FIG. 1, and the difference is mainly demonstrated below.

図３（ａ），（ｂ）に示すように保持カバー６の外表面にはその全体を覆うように伝熱シート７の一端部が接着されている。伝熱シート７は熱伝導率が高く可撓性のあるシート状部材であり、伝熱シート７の他端部は回動軸３の外周面に巻き付けて密着されている。これによりＨＤＤ４からの熱は緩衝材５，保持カバー６，伝熱シート７を介して熱伝導により回動軸３に伝熱される。この場合、ＨＤＤ４から伝熱シート７への伝熱性を高めるためには、緩衝材５や保持カバー６を熱伝導率の高い材質により形成することが好ましい。   As shown in FIGS. 3A and 3B, one end of the heat transfer sheet 7 is bonded to the outer surface of the holding cover 6 so as to cover the entire surface. The heat transfer sheet 7 is a flexible sheet-like member having high thermal conductivity, and the other end portion of the heat transfer sheet 7 is wound around and closely attached to the outer peripheral surface of the rotating shaft 3. Thereby, the heat from the HDD 4 is transferred to the rotating shaft 3 by heat conduction through the buffer material 5, the holding cover 6, and the heat transfer sheet 7. In this case, in order to improve the heat transfer property from the HDD 4 to the heat transfer sheet 7, it is preferable to form the buffer material 5 and the holding cover 6 with a material having high thermal conductivity.

このように第３の実施の形態では、ＨＤＤ４の近傍に伝熱シート７の一端部を接着し、伝熱シート７の他端部を回動軸３に捲着するようにしたので、ＨＤＤ４から回動軸３への伝熱性が高まり、ＨＤＤ４の温度上昇を効果的に抑制することができる。   As described above, in the third embodiment, one end portion of the heat transfer sheet 7 is bonded to the vicinity of the HDD 4 and the other end portion of the heat transfer sheet 7 is attached to the rotating shaft 3. The heat transfer to the rotating shaft 3 is enhanced, and the temperature rise of the HDD 4 can be effectively suppressed.

なお、図３（ａ），（ｂ）では伝熱シート７の一端部を保持カバー６の外表面に接着するようにしたが、図３（ｃ）に示すように保持カバー６の内表面に接着するようにしてもよい。また、図３ではフレキシブル基板３０を回動軸３に巻き付けているが、伝熱シート７を用いてＨＤＤ４からの熱を回動軸３に伝熱する場合には、必ずしもその必要はない。   3 (a) and 3 (b), one end of the heat transfer sheet 7 is bonded to the outer surface of the holding cover 6. However, as shown in FIG. You may make it adhere | attach. In FIG. 3, the flexible substrate 30 is wound around the rotation shaft 3, but this is not necessarily required when heat from the HDD 4 is transferred to the rotation shaft 3 using the heat transfer sheet 7.

−第４の実施の形態−
図４を参照して本発明による第４の実施の形態について説明する。
第３の実施の形態では、伝熱シート７を介してＨＤＤ４からの熱を回動軸３に伝熱するようにしたが、第４の実施の形態では、ＨＤＤ４を保持する保持部材としての保持カバー６１を回動軸３の近傍まで延設し、保持カバー６１を介してＨＤＤ４からの熱を回動軸３に伝熱する。 -Fourth embodiment-
A fourth embodiment of the present invention will be described with reference to FIG.
In the third embodiment, the heat from the HDD 4 is transferred to the rotating shaft 3 via the heat transfer sheet 7. In the fourth embodiment, however, the holding member is a holding member that holds the HDD 4. The cover 61 is extended to the vicinity of the rotating shaft 3, and heat from the HDD 4 is transferred to the rotating shaft 3 through the holding cover 61.

図４（ａ）は、第４の実施の形態に係る携帯電話の内部構造を示す正面図であり、図４（ｂ），（ｃ）はそれぞれこの携帯電話の縦断面図（図４（ａ）のｂ−ｂ線断面図）、図４（ｄ）は図４（ａ）のｄ−ｄ線断面図、図４（ｅ）は図４（ａ）のｅ−ｅ線断面図である。図４（ａ），（ｂ）は携帯電話を開いた状態を示し、図４（ｃ）は閉じた状態を示している。なお、図３と同一の箇所には同一の符号を付し、以下ではその相違点を主に説明する。   FIG. 4A is a front view showing the internal structure of the mobile phone according to the fourth embodiment, and FIGS. 4B and 4C are longitudinal sectional views of the mobile phone (FIG. 4A). 4B is a cross-sectional view taken along the line dd of FIG. 4A, and FIG. 4E is a cross-sectional view taken along the line ee of FIG. 4A. 4A and 4B show a state in which the mobile phone is opened, and FIG. 4C shows a state in which the mobile phone is closed. In addition, the same code | symbol is attached | subjected to the location same as FIG. 3, and the difference is mainly demonstrated below.

下本体２のボディ上端の凸部１０ｄ（ヒンジ部ＨＧ）は、上本体２のボディ２０の厚さ分だけ前方に突出した形状（断面略Ｌ字状）をなしている。この下本体２側の凸部１０ｄは上本体２のボディ上端の凸部２０ｅ，２０ｆの間に嵌合し、下本体１と上本体２は回動軸３を介して互いに回動可能に連結されている。保持カバー６１の上端は凸部１０ｄに至るまで延設され、凸部１０ｄ内において回動軸３から所定距離隔てて回動軸３を囲むように円弧状に形成されている。   The convex portion 10d (hinge portion HG) at the upper end of the body of the lower main body 2 has a shape (substantially L-shaped in cross section) protruding forward by the thickness of the body 20 of the upper main body 2. The convex portion 10d on the lower main body 2 side is fitted between the convex portions 20e and 20f on the upper end of the upper main body 2, and the lower main body 1 and the upper main body 2 are connected to each other via a rotary shaft 3 so as to be rotatable. Has been. The upper end of the holding cover 61 extends to reach the convex portion 10d, and is formed in an arc shape so as to surround the rotational shaft 3 at a predetermined distance from the rotational shaft 3 in the convex portion 10d.

回動軸３の外周面には、周方向一部に断面略扇形の突起部３２が設けられ、突起部３２の外周端面は保持カバー６１の表面を摺動可能となっている。突起部３２は上本体２と一体に回動し、図４（ｂ）に示すように携帯電話を開いた状態では突起部３２が保持カバー６１に接触する。一方、図４（ｃ）に示すように携帯電話を閉じた状態では突起部３２が保持カバー６１から離間する。   On the outer peripheral surface of the rotating shaft 3, a protruding portion 32 having a substantially sectoral cross section is provided in a part in the circumferential direction, and the outer peripheral end surface of the protruding portion 32 can slide on the surface of the holding cover 61. The protrusion 32 rotates integrally with the upper main body 2, and the protrusion 32 comes into contact with the holding cover 61 when the mobile phone is opened as shown in FIG. On the other hand, as shown in FIG. 4C, the protrusion 32 is separated from the holding cover 61 when the mobile phone is closed.

第４の実施の形態では、例えば携帯電話を開いた状態でのみＨＤＤ４を作動可能とする。これによりＨＤＤ４を作動するときは突起部３２が保持カバー６１に接触するため、ＨＤＤ４からの熱は保持カバー６１および突起部３２を介して熱伝導により回動軸３に伝えられ、回動軸３の側端面から放熱される。この場合、ＨＤＤ４から回動軸３への伝熱性を高めるためには、緩衝材５や保持カバー６１を熱伝導率の高い材質により形成することが好ましい。一方、携帯電話を閉じた状態では突起部３２が保持カバー６１から離間し、ＨＤＤ４から回動軸３への伝熱は阻止されるが、この場合にはＨＤＤ４からの発熱はないため、ＨＤＤ４の温度上昇は問題とならない。   In the fourth embodiment, for example, the HDD 4 can be operated only when the mobile phone is opened. Thus, when the HDD 4 is operated, the protrusion 32 comes into contact with the holding cover 61, so that heat from the HDD 4 is transmitted to the rotating shaft 3 by heat conduction through the holding cover 61 and the protruding portion 32. Heat is radiated from the side end face. In this case, in order to improve the heat transfer from the HDD 4 to the rotating shaft 3, it is preferable to form the cushioning material 5 and the holding cover 61 with a material having high thermal conductivity. On the other hand, when the cellular phone is closed, the protrusion 32 is separated from the holding cover 61 and heat transfer from the HDD 4 to the rotating shaft 3 is prevented. However, in this case, there is no heat generation from the HDD 4, so Temperature rise is not a problem.

このように第４の実施の形態では保持カバー６１の上端部を回動軸３の近傍まで延設し、突起部３２を介して回動軸３に接触させるようにしたので、伝熱部材を別途設けなくてもＨＤＤ４からの熱を回動軸３から放熱することができ、ＨＤＤ４の温度上昇を抑制することができる。また、突起部３２を回動軸３の周面の周方向一部に設け、携帯電話を開いた状態、すなわちＨＤＤ４の作動状態でのみ突起部３２が保持カバー６１に接触するようにしたので、突起部３２と保持カバー６１の摺動範囲が狭く、耐久性の悪化を防ぐことができる。突起部３２を必要範囲にのみ設けるので、スペースも節約できる。   As described above, in the fourth embodiment, the upper end portion of the holding cover 61 is extended to the vicinity of the rotating shaft 3 and is brought into contact with the rotating shaft 3 via the protrusion 32. Even if it is not provided separately, the heat from the HDD 4 can be dissipated from the rotating shaft 3, and the temperature rise of the HDD 4 can be suppressed. Further, the protrusion 32 is provided on a part of the circumferential surface of the rotating shaft 3 so that the protrusion 32 contacts the holding cover 61 only when the mobile phone is opened, that is, when the HDD 4 is in operation. The sliding range between the protrusion 32 and the holding cover 61 is narrow, and deterioration of durability can be prevented. Since the protrusion 32 is provided only in a necessary range, a space can be saved.

なお、第４の実施の形態では、携帯電話を開いた状態でのみＨＤＤ４を作動可能としたが、携帯電話を閉じた状態でＨＤＤ４が作動可能であってもよく、その場合には、携帯電話の開閉状態に拘わらず、突起部３２が保持カバー６１に常時接触するように突起部３２および保持カバー６１を形成すればよい。例えば図５に示すように突起部３２の代わりに回動軸３の外周面の全周にわって突起部３３を設け、突起部３３を介して回動軸３と保持カバー６１とが常時接触するようにすればよい。   In the fourth embodiment, the HDD 4 can be operated only when the mobile phone is open. However, the HDD 4 may be operable when the mobile phone is closed. What is necessary is just to form the protrusion part 32 and the holding | maintenance cover 61 so that the protrusion part 32 may always contact the holding | maintenance cover 61 irrespective of the open / closed state. For example, as shown in FIG. 5, instead of the protrusion 32, a protrusion 33 is provided along the entire outer peripheral surface of the rotation shaft 3, and the rotation shaft 3 and the holding cover 61 are always in contact via the protrusion 33. You just have to do it.

以上では、ＨＤＤ４からの熱を回動軸３から放熱するようにしたが、回動軸３からの放熱性を高めるために、回動軸３の側端面を貫通して回動軸３の内部に通気孔を設け、通気孔を介して回動軸３の内部の高温の空気を外部に排出するようにしてもよい。この場合、通気孔を防水シートで覆って、回動軸３の内部に水が侵入しないようにすることが好ましい。   In the above, heat from the HDD 4 is radiated from the rotating shaft 3, but in order to improve heat dissipation from the rotating shaft 3, the side end surface of the rotating shaft 3 is penetrated to the inside of the rotating shaft 3. A vent hole may be provided in the hot shaft, and hot air inside the rotating shaft 3 may be discharged to the outside through the vent hole. In this case, it is preferable to cover the vent hole with a waterproof sheet so that water does not enter the inside of the rotating shaft 3.

なお、携帯電話のボディ１０，２０にカメラレンズを取り付けて、カメラ付き携帯電話とすることもできる。この場合、ＨＤＤ４からの熱によりＣＣＤ等の撮像素子が温度上昇することを避けるため、撮像素子をＨＤＤ４から離して配置することが好ましく、例えば上本体２のボディ２０内に撮像素子を収容配置することが好ましい。   In addition, a camera lens can be attached to the body 10 or 20 of the mobile phone to make a mobile phone with a camera. In this case, in order to avoid the temperature of the image sensor such as a CCD from being increased by heat from the HDD 4, the image sensor is preferably arranged away from the HDD 4. For example, the image sensor is accommodated in the body 20 of the upper main body 2. It is preferable.

上記実施の形態では、ＨＤＤ４を含む各種部品を収容する下本体１（第１の本体部）と他の各種部品を収容する上本体２（第２の本体部）を、ヒンジ部ＨＧ（連結部）において回動軸３を介して回動可能に連結したが、これら第１の本体，第２の本体、連結部の構成は上述したものに限定されない。保護シート３１（図１，２）や伝熱シート７（図３）や保持カバー６１（図４，５）を介して、ＨＤＤ４からの熱をヒンジ部ＨＧの回動軸３に伝えるようにしたが、伝熱部材の構成はこれに限らない。ヒンジ部ＨＧは外部に接する面積が大きく、放熱性が高いため、ＨＤＤ４からの熱を回動軸以外のヒンジ部ＨＧへ伝熱するように伝熱部材を構成してもよい。   In the above embodiment, the lower main body 1 (first main body portion) that accommodates various components including the HDD 4 and the upper main body 2 (second main body portion) that accommodates other various components are connected to the hinge portion HG (connecting portion). However, the configurations of the first main body, the second main body, and the connecting portion are not limited to those described above. Heat from the HDD 4 is transmitted to the rotating shaft 3 of the hinge part HG via the protective sheet 31 (FIGS. 1 and 2), the heat transfer sheet 7 (FIG. 3) and the holding cover 61 (FIGS. 4 and 5). However, the configuration of the heat transfer member is not limited to this. Since the hinge part HG has a large area in contact with the outside and high heat dissipation, the heat transfer member may be configured to transfer heat from the HDD 4 to the hinge part HG other than the rotating shaft.

以上では、ＨＤＤ４を内蔵した携帯電話に本発明を適用したが、他の情報記憶用のディスク装置を内蔵した携帯電話であって、このディスク装置の発熱が問題となるようなものにも本発明を同様に適用することができる。また、携帯電話以外の携帯通信端末（例えば通信機能を有するＰＤＡ等）にも本発明を適用することが可能である。すなわち、本発明の特徴、機能を実現できる限り、本発明は実施の形態の携帯通信端末に限定されない。なお、以上の説明はあくまで一例であり、発明を解釈する際、上記実施形態の記載事項と特許請求の範囲の記載事項の対応関係になんら限定も拘束もされない。   In the above description, the present invention is applied to a mobile phone having a built-in HDD 4. However, the present invention is also applied to a mobile phone having a built-in disk device for storing other information, in which heat generation of this disk device becomes a problem. Can be applied as well. Further, the present invention can be applied to a mobile communication terminal other than a mobile phone (for example, a PDA having a communication function). That is, the present invention is not limited to the mobile communication terminal of the embodiment as long as the features and functions of the present invention can be realized. The above description is merely an example, and when interpreting the invention, there is no limitation or restriction on the correspondence between the items described in the embodiment and the items described in the claims.
