しかしながら、従来の２つの筐体がヒンジ機構により連結されている装置では、筐体のいずれか一方のみにバッテリなどの電源があるため２つの筐体間で電力を供給するためにはケーブル等の有線を用いて行う必要がある。そして、ケーブル等は、端末装置の組み立て工程におけるメンテナンス性に問題を発生させていた。すなわち、ケーブル等を筐体内に収容するためにその取り回しに手間がかかるといった不都合があった。 However, in a conventional device in which two housings are connected by a hinge mechanism, only one of the housings has a power source such as a battery, so a cable or the like is required to supply power between the two housings. It is necessary to do it using cable. And cables and the like have caused problems in maintainability in the terminal device assembly process. That is, there is a problem in that it takes time to handle the cables and the like in order to be accommodated in the housing.

The hinge mechanism is electrically connected to the conductive means provided in the first housing, which constitutes the shaft portion of the hinge mechanism, and is relatively rotatable and electrically connected to the conductive means. And connecting means provided in the second casing.

また、本発明に係る端末装置は、電源及び基準電位部を有する第１の筐体と、前記第１の筐体と、ヒンジ機構を介して開閉自在に連結される第２の筐体と、前記電源の電力を前記第２の筐体側に供給するための、前記第２の筐体に設けられた第１の接続手段と、前記第２の筐体に備える基準電位部と接続するための、前記第２の筐体に設けられた第２の接続手段とを備え、前記ヒンジ機構は、前記電源と電気的に接続されていると共に、前記第１の接続手段と相対的に回動自在かつ電気的に接続された、前記ヒンジ機構の軸部を構成する電力供給手段と、前記第１の筐体の基準電位部と接続されていると共に、前記第２の接続手段と相対的に回動自在かつ電気的に接続された、前記ヒンジ機構の軸部を構成する接地手段とを備える。 In addition, a terminal device according to the present invention includes a first housing having a power source and a reference potential unit, the first housing, and a second housing connected to be opened and closed through a hinge mechanism, A first connection means provided in the second casing for supplying power of the power source to the second casing, and a reference potential section provided in the second casing. And a second connecting means provided in the second housing, wherein the hinge mechanism is electrically connected to the power source and is rotatable relative to the first connecting means. And electrically connected to the power supply means constituting the shaft portion of the hinge mechanism and to the reference potential portion of the first casing, and to rotate relative to the second connection means. And a grounding means which constitutes a shaft portion of the hinge mechanism, which is movable and electrically connected.

また、本発明に係る端末装置は、前記ヒンジ機構は、前記電力供給手段と前記接地手段との間に絶縁性の絶縁手段を有し、前記電力供給手段、接地手段及び絶縁手段が組み付けられて前記ヒンジ機構の軸部が構成される。 In the terminal device according to the present invention, the hinge mechanism includes an insulating insulating means between the power supply means and the grounding means, and the power supply means, the grounding means, and the insulating means are assembled. A shaft portion of the hinge mechanism is configured.

このように、本発明によれば、第１の筐体と第２の筐体とがヒンジ機構により開閉自在に連結されている場合において、第１の筐体と第２の筐体とが、ヒンジ機構の軸部を構成する導電手段と接続手段とを介して互いに電気的に接続されて導通されるため、ヒンジ機構が第１の筐体と第２の筐体との間の導通手段となり、この導通手段を用いて、第１の筐体から第２の筐体へとケーブル等の有線を用いずに、信号や電力を供給することができる。そのため、本発明は、ケーブル等を筐体内に収容するためにその取り回しに手間がかかるといった不都合を低減し、ケーブル等による、端末装置の組み立て工程におけるメンテナンス性の低下を防止することができる。 Thus, according to the present invention, in the case where the first housing and the second housing are connected to be freely opened and closed by the hinge mechanism, the first housing and the second housing are: Since the conductive means and the connecting means constituting the shaft portion of the hinge mechanism are electrically connected to each other and conducted, the hinge mechanism becomes a conducting means between the first casing and the second casing. Using this conduction means, signals and power can be supplied from the first housing to the second housing without using wires such as cables. Therefore, the present invention reduces the inconvenience that it takes time to handle the cable and the like in order to accommodate the cable and the like in the housing, and can prevent the maintainability in the terminal device assembly process due to the cable and the like.

The power supply means constituting the shaft portion of the first power supply means and the first connection means are electrically connected to the power source of the first housing, and the grounding means constituting the shaft portion of the hinge mechanism and the second connection Is electrically connected to the reference potential portion of the first casing through the means, so that the effect when the cable or the like becomes unnecessary is obtained, and the second power is supplied from the power supply of the first casing. Electric power can be supplied to the housing without using a cable or the like.

すなわち、本発明によれば、第１の筐体の電源から第２の筐体へと電力を供給する場合であっても、電力供給用や接地用のケーブルに置き換えてヒンジ機構の軸部を用いるため、ケーブルが不要になることから組み付け性を向上させることができる。さらに、これらのケーブル等を通過させるためにヒンジ機構内部を中空とする必要が無くなり、ヒンジ機構の軸等の径を小さくしてヒンジ機構を薄型化及び小型化しても、ヒンジ機構の剛性を高く維持することができ、このヒンジ機構を用いた装置の薄型化及び小型化が可能となる。 That is, according to the present invention, even when power is supplied from the power supply of the first housing to the second housing, the shaft portion of the hinge mechanism is replaced with a power supply or grounding cable. Since it uses, since a cable becomes unnecessary, an assembly property can be improved. Furthermore, it is not necessary to make the hinge mechanism hollow in order to pass these cables, and the rigidity of the hinge mechanism is increased even if the diameter of the shaft of the hinge mechanism is reduced to make the hinge mechanism thinner and smaller. Therefore, it is possible to reduce the thickness and size of the device using the hinge mechanism.

Thus, the power from the battery 102 of the lower housing 121 can be supplied to the upper housing 122 via the shaft portion of the hinge mechanism without using a cable or the like. Therefore, in the mobile phone of this embodiment, a power supply cable and a grounding cable are not required between the upper housing 122 and the lower housing 121.

また、本発明に係る端末装置の一実施形態の携帯電話によれば、電力供給用端子１１５及びアース用端子１１４が、バネ端子１１６により付勢されてヒンジ機構の円柱表面形状の部分に、この円柱の軸を中心として回動自在に接触しているため、上部筐体１２２と下部筺体１２１とが開状態の間、閉状態の間、及び開閉動作がなされている間のいずれの間においてもバッテリを有する下部筐体１２１から上部筐体１２２へ電力を供給することができると共に、これらのいずれの間においても上部筐体１２２を接地することができる。また、本発明に係る端末装置の一実施形態の携帯電話によれば、上部筐体１２２と下部筐体１２１との間における、ケーブル等による導通を、ヒンジ機構を介した導通に置き換えているため、ケーブル等を用いて導通を行っている場合に比べて、組み付け性を向上させることができる。 Further, according to the mobile phone of the embodiment of the terminal device according to the present invention, the power supply terminal 115 and the grounding terminal 114 are urged by the spring terminal 116 to the cylindrical surface shape portion of the hinge mechanism. Since the upper casing 122 and the lower casing 121 are in contact with each other so as to be rotatable about the axis of the cylinder, the upper casing 122 and the lower casing 121 are in an open state, in a closed state, and during an open / close operation. Electric power can be supplied from the lower housing 121 having a battery to the upper housing 122, and the upper housing 122 can be grounded between them. In addition, according to the mobile phone of the embodiment of the terminal device according to the present invention, the continuity by the cable or the like between the upper casing 122 and the lower casing 121 is replaced with the continuity through the hinge mechanism. Assembling property can be improved as compared with the case where conduction is performed using a cable or the like.

本実施形態ではヒンジ支持部材１０９を、アース用部材２０１と電力供給用部材２０３との間に絶縁性の樹脂部材である絶縁用部材２０２を挟んだ３つの部材で構成することにより、ヒンジ機構を構成するヒンジ支持部材１０９の１つの部材で、２つの筐体間における電源供給用の部材の機能とアース用の部材の機能との２つの機能を実現する。 In this embodiment, the hinge support member 109 is composed of three members that sandwich an insulating member 202 that is an insulating resin member between a grounding member 201 and a power supply member 203, thereby providing a hinge mechanism. One member of the hinge support member 109 to be configured realizes two functions, that is, a function of a power supply member between two housings and a function of a grounding member.

また、本発明に係る端末装置の一実施形態では、上部筐体１２２と下部筐体１２１との間において、情報の送受信が電波を用いた無線通信により行われているため、ケーブルを用いずに情報の送受信を行うことができる。なお、これに対して、本発明に係る端末装置では、上部筐体と下部筐体との間において、情報の送受信をケーブル等を用いて行うとしても良い。この場合、情報の送受信はケーブル等を用いて行うが、電力の供給がヒンジ機構の軸部を介して行われケーブル等が不要となるため、この不要となったケーブル等の分において、筐体の組み付け性の向上を図ることができる。 Moreover, in one embodiment of the terminal device according to the present invention, since information is transmitted and received between the upper housing 122 and the lower housing 121 by radio communication using radio waves, a cable is not used. Information can be sent and received. In contrast, in the terminal device according to the present invention, information may be transmitted and received between the upper housing and the lower housing using a cable or the like. In this case, transmission / reception of information is performed using a cable or the like. However, since power is supplied through the shaft portion of the hinge mechanism and the cable is unnecessary, the casing is divided into the unnecessary cable and the like. Assembling performance can be improved.

このように、本発明に係る端末装置の一実施形態の携帯電話では、上部筐体１２２と下部筐体１２１との間における電力の供給をケーブルを用いずに行うことができる。 Thus, in the mobile phone of one embodiment of the terminal device according to the present invention, power can be supplied between the upper housing 122 and the lower housing 121 without using a cable.

また、本発明に係る端末装置の一実施形態の携帯電話では、ヒンジ機構のヒンジ支持部材１０９の軸部に、従来技術のような電力供給用のケーブルを通過させるための中空部分を設ける必要がなくなり、中空部を小さく又は中実とすることができるため、ヒンジ軸部の剛性を維持しつつ、ヒンジ機構の薄型化、小型化が可能となる。したがって、このヒンジ機構を用いた携帯電話の薄型化、小型化も可能となる。 Further, in the mobile phone according to the embodiment of the terminal device according to the present invention, it is necessary to provide a hollow portion for allowing a power supply cable to pass therethrough in the shaft portion of the hinge support member 109 of the hinge mechanism. Since the hollow portion can be made small or solid, the hinge mechanism can be thinned and miniaturized while maintaining the rigidity of the hinge shaft portion. Therefore, it is possible to reduce the thickness and size of a mobile phone using this hinge mechanism.

また、本発明に係る端末装置の一実施形態の携帯電話では、上部筐体１２２と下部筐体１２１との間における電力の供給をケーブルを用いずに行うことができるため、従来技術で必要であった電力供給用や接地用のケーブル等を設けるために必要なコストを削減し、電力供給用や接地用のケーブル等を形成するための製造工数を削減することができる。 In addition, in the mobile phone according to an embodiment of the terminal device according to the present invention, power can be supplied between the upper housing 122 and the lower housing 121 without using a cable, which is necessary in the related art. It is possible to reduce the cost required for providing the power supply and grounding cables, and to reduce the number of manufacturing steps for forming the power supply and grounding cables.

また、本発明に係る端末装置の一実施形態では、上部筐体１２２に設けられた電力供給用端子１１５とアース用端子１１４とが、それぞれ、バネ端子１１６により付勢されつつ、電力供給用部材２０３とアース用部材２０１の円柱形状部分に、この円柱の軸を中心として相対的に回動自在に電気的に接するため、ヒンジ機構が回転動作を行い、ヒンジ機構の軸を中心として上部筐体１２２と下部筐体１２１とが開閉動作を行う場合であっても、電力供給用端子１１５及びアース用端子１１４の電力供給用部材２０３及びアース用部材２０１への電気的な接続状態を維持することができ、下部筐体側から上部筐体側への電力の供給を継続させることができる。 In one embodiment of the terminal device according to the present invention, the power supply terminal 115 and the grounding terminal 114 provided on the upper housing 122 are respectively urged by the spring terminal 116 and the power supply member. 203 and the cylindrical portion of the grounding member 201 are in electrical contact with each other so as to be relatively rotatable about the axis of the cylinder, so that the hinge mechanism rotates, and the upper casing is centered on the axis of the hinge mechanism. Even when 122 and the lower housing 121 are opened and closed, the electrical connection state of the power supply terminal 115 and the ground terminal 114 to the power supply member 203 and the ground member 201 is maintained. The power supply from the lower housing side to the upper housing side can be continued.

また、ヒンジ機構には上部筐体１２２と下部筐体１２１との開閉動作に伴い高負荷が発生するので、ヒンジ機構のヒンジ支持部には金属製の部材を使用することが必要となるが、本発明に係る端末装置の一実施形態では、ヒンジ支持部材１０９のアース用部材２０１及び電力供給用部材２０３を金属で形成することによりこの要件を満足している。 In addition, since a high load is generated in the hinge mechanism in accordance with the opening / closing operation of the upper casing 122 and the lower casing 121, it is necessary to use a metal member for the hinge support portion of the hinge mechanism. In one embodiment of the terminal device according to the present invention, this requirement is satisfied by forming the grounding member 201 and the power supply member 203 of the hinge support member 109 from metal.

なお、本発明に係る端末装置の一実施形態では、図１及び図２に示されるように、ヒンジ機構は、本実施形態の携帯電話が閉じられている状態において、上部筐体側から下部筐体側へと向かう方向に、電力供給用部材２０３、絶縁用部材２０２及びアース用部材２０１という順序で組み付けられているが、本発明の端末装置はこのような場合に限定されるものではなく、下部筐体側から上部筐体側へと向かう方向に、電力供給用部材、絶縁用部材及びアース用部材という順序で組み付けられていても良い。 In the embodiment of the terminal device according to the present invention, as shown in FIG. 1 and FIG. 2, the hinge mechanism is arranged from the upper housing side to the lower housing side in the state where the mobile phone of the present embodiment is closed. The power supply member 203, the insulating member 202, and the grounding member 201 are assembled in the direction toward the head in this order. However, the terminal device of the present invention is not limited to such a case, and the lower casing is not limited thereto. The power supply member, the insulating member, and the ground member may be assembled in the order from the body side to the upper housing side.

なお、上記本発明に係る端末装置の一実施形態である携帯電話では、バッテリ１０２を、ヒンジ機構の軸部を構成するヒンジ支持部材１０９を有する筐体側である下部筐体側に設けているが、本発明はこのような場合に限定されるものではなく、バッテリをヒンジ機構の軸部を構成するヒンジ支持部材（実施形態でのヒンジ支持部材１０９に該当）を有していない方の筐体に設けるとしても良い。 In the mobile phone that is one embodiment of the terminal device according to the present invention, the battery 102 is provided on the lower housing side, which is the housing side having the hinge support member 109 that constitutes the shaft portion of the hinge mechanism. The present invention is not limited to such a case, and the battery is mounted on the casing that does not have the hinge support member (corresponding to the hinge support member 109 in the embodiment) that constitutes the shaft portion of the hinge mechanism. It may be provided.

さらに、本発明に係る端末装置の一実施形態である携帯電話では、上部筐体１２２と下部筐体１２１との間における情報の送受信を無線電波による無線通信により行うとしているが、本発明はこのような場合に限定されるものではなく、上部筐体１２２と下部筐体１２１との間の情報の送受信を、光ファイバを用いて行うとしても良い。この光ファイバの心数は、１つでも複数でも良い。この上部筐体１２２と下部筐体１２１との間の情報の送受信を、光ファイバを用いて行う場合について図６を参照して説明する。 Furthermore, in the mobile phone which is an embodiment of the terminal device according to the present invention, information is transmitted and received between the upper housing 122 and the lower housing 121 by wireless communication using wireless radio waves. The present invention is not limited to such a case, and information transmission / reception between the upper housing 122 and the lower housing 121 may be performed using an optical fiber. The number of optical fibers may be one or more. A case where information transmission / reception between the upper housing 122 and the lower housing 121 is performed using an optical fiber will be described with reference to FIG.

図６は、図１に示されるヒンジ支持部材１０９の変形例の構成図である。なお、この光ファイバを用いる構成では、ヒンジ機構の軸部３０１に光ファイバ６０１を通過させるための中空部分６０２を設ける構成とした以外は、前述の図１から図５を用いて説明した携帯電話の実施形態と同様の構成であり、前述の図１から図５を用いて説明した携帯電話の実施形態と同様の説明が成り立つため、その説明を省略する。 FIG. 6 is a configuration diagram of a modified example of the hinge support member 109 shown in FIG. In the configuration using this optical fiber, the cellular phone described with reference to FIGS. 1 to 5 is used except that the hollow portion 602 for allowing the optical fiber 601 to pass is provided in the shaft portion 301 of the hinge mechanism. The configuration is the same as that of the embodiment described above, and the same description as that of the embodiment of the mobile phone described with reference to FIGS.

図６に示されるように、光ファイバ６０１を上部筐体１２２と下部筐体１２１との間の情報の送受信に用いる場合、ヒンジ支持部材１０９には、光ファイバ６０１により上部筐体１２２と下部筐体１２１との間を接続するため、光ファイバ６０１を通過させるための中空部分６０２が軸部３０１の略軸中心の位置に設けられている。この中空部分６０２は軸部３０１の軸方向に向かって略直線状に貫通しており、内部に光ファイバ６０１を挿入させることができるようになっている。 As shown in FIG. 6, when the optical fiber 601 is used for transmission / reception of information between the upper casing 122 and the lower casing 121, the hinge supporting member 109 is connected to the upper casing 122 and the lower casing by the optical fiber 601. A hollow portion 602 for allowing the optical fiber 601 to pass therethrough is provided at a substantially axial center position of the shaft portion 301 in order to connect the body 121. The hollow portion 602 penetrates substantially linearly in the axial direction of the shaft portion 301 so that the optical fiber 601 can be inserted therein.

光ファイバ６０１により上部筐体１２２と下部筐体１２１との間で情報の送受信を行う場合であっても、本発明によれば、電力供給用や接地用のケーブル等は不要であり、光ファイバ６０１の径は小さいため、光ファイバ６０１を通過させるための中空部分６０２がヒンジ機構の軸部３０１に存在したとしても、ヒンジ機構の剛性を高く確保でき、かつ、ヒンジ機構の薄型化、小型化を図ることができる。 Even when information is transmitted and received between the upper housing 122 and the lower housing 121 by the optical fiber 601, according to the present invention, a power supply cable, a grounding cable, and the like are not necessary. Since the diameter of 601 is small, even if the hollow portion 602 for allowing the optical fiber 601 to pass through exists in the shaft portion 301 of the hinge mechanism, the hinge mechanism can have high rigidity, and the hinge mechanism can be made thinner and smaller. Can be achieved.

また、上述の本発明に係る端末装置の一実施形態である携帯電話では、上部筐体１２２と下部筐体１２１との間において電力の供給を行うケーブルによる導通手段をヒンジ機構の軸部を介した導通手段に置き換えているが、本発明に係る端末装置はこのような場合に限定されるものではない。すなわち、本発明に係る端末装置は、信号の送受信をヒンジ機構の軸部を用いて行うとしても良い。この場合、例えば、図４に示されるアース用部材２０１とアース用端子１１４、及び、電力供給用部材２０３と電力供給用端子１１５の少なくともいずれか一方が、上部筐体１２２と下部筐体１２１との間において信号を送受信するための信号線となる。 Further, in the mobile phone which is an embodiment of the terminal device according to the present invention described above, the conduction means by the cable for supplying power between the upper housing 122 and the lower housing 121 is provided via the shaft portion of the hinge mechanism. However, the terminal device according to the present invention is not limited to such a case. That is, the terminal device according to the present invention may perform signal transmission / reception using the shaft portion of the hinge mechanism. In this case, for example, at least one of the ground member 201 and the ground terminal 114 and the power supply member 203 and the power supply terminal 115 shown in FIG. It becomes a signal line for transmitting and receiving signals between.

すなわち、信号の送受信をヒンジ機構の軸部を用いて行う場合、上述の説明のように、アース用部材２０１とアース用端子１１４とが電気的に接続されて上部筐体１２２と下部筐体１２１とを導通させて信号線となり、電力供給用部材２０３と電力供給用端子１１５とが電気的に接続されて上部筐体１２２と下部筐体１２１とを導通させて信号線となる。この場合であっても、上部筐体１２２と下部筐体１２１との間で信号の送受信を行ためのケーブルをヒンジ機構の軸による導通手段に置き換えているため、ケーブル等を用いて導通を行っている場合に比べて、組み付け性を向上させることができる。なお、この信号の送受信をヒンジ機構の軸部を用いて行う場合、上部筐体１２２と下部筐体１２１との間の電力の供給をケーブルを用いて行う。 That is, when signal transmission / reception is performed using the shaft portion of the hinge mechanism, as described above, the ground member 201 and the ground terminal 114 are electrically connected, and the upper housing 122 and the lower housing 121 are connected. And the power supply member 203 and the power supply terminal 115 are electrically connected, and the upper housing 122 and the lower housing 121 are electrically connected to form a signal line. Even in this case, since the cable for transmitting and receiving signals between the upper housing 122 and the lower housing 121 is replaced with the conduction means using the shaft of the hinge mechanism, the cable is used for conduction. Compared with the case where it has, the assembly | attachment property can be improved. Note that when transmission / reception of this signal is performed using the shaft portion of the hinge mechanism, power is supplied between the upper housing 122 and the lower housing 121 using a cable.
