Description

本発明は、例えば車両や住宅などに用いられる無線通信システムにあってこれら車両や住宅などの通信対象との間で無線通信を行う携帯機に関する。 The present invention relates to a portable communication device that is used in, for example, a vehicle or a house and performs wireless communication with a communication target such as the vehicle or the house.

こうした無線通信システムの一つとして、ユーザが携帯機（電子キー）を所持した状態で車両ドアに接近することにより車両ドアのアンロックが自動的に実行されるとともに、ユーザが車室内に入ることによりエンジンの始動等が許可される、いわゆる車両の電子キーシステムが周知である。図７に、こうした電子キーシステムの概要を示す。 As one of such wireless communication systems, when the user approaches the vehicle door while holding the portable device (electronic key), the vehicle door is automatically unlocked and the user enters the vehicle interior. A so-called electronic key system for a vehicle in which starting of the engine or the like is permitted by the above is well known. FIG. 7 shows an outline of such an electronic key system.

同図７に示されるように、この電子キーシステムでは、例えば車両ドアに設けられた送信装置１０１から車両ドアの周辺に設定された通信可能エリアＡにリクエスト信号を送信する。またこの電子キーシステムでは、この送信装置１０１から送信されるリクエスト信号を受信するとともに、この受信したリクエスト信号に対して識別コード（ＩＤコード）等の情報を含む応答信号を送信する携帯機２００をユーザが所持する。すなわち、携帯機２００を所持したユーザが通信可能エリアＡ内に進入することによって、同携帯機２００から応答信号が送信される。そしてこのシステムにおいて、携帯機２００から送信される応答信号は車室内に設けられた受信装置１０２により受信されて、車両にかかる各種制御を実行する車両側制御装置１０３に伝達される。同制御装置１０３では、この受信された応答信号に含まれる携帯機２００のＩＤコードと同制御装置１０３内のメモリ等に予め記憶されているＩＤコードとの照合を行い、この照合を通じて、例えば車両ドアに設けられているドアロック機構１０４のアンロックを実行する。このような電子キーシステムによれば、ユーザの直接的な手動操作によることなく車両の各種操作が自動的に行われるようになるため、車両の操作にかかる利便性が大きく向上するようになる。 As shown in FIG. 7, in this electronic key system, for example, a request signal is transmitted from a transmission device 101 provided in a vehicle door to a communicable area A set around the vehicle door. In the electronic key system, the portable device 200 that receives the request signal transmitted from the transmission device 101 and transmits a response signal including information such as an identification code (ID code) to the received request signal is provided. Owned by the user. That is, when the user who has the portable device 200 enters the communicable area A, a response signal is transmitted from the portable device 200. In this system, the response signal transmitted from the portable device 200 is received by the receiving device 102 provided in the vehicle interior, and is transmitted to the vehicle-side control device 103 that executes various controls relating to the vehicle. The control device 103 collates the ID code of the portable device 200 included in the received response signal with the ID code stored in advance in the memory or the like in the control device 103, and through this collation, for example, the vehicle The door lock mechanism 104 provided on the door is unlocked. According to such an electronic key system, various operations of the vehicle are automatically performed without direct manual operation by the user, so that the convenience of the operation of the vehicle is greatly improved.

そして従来、こうした電子キーシステムに用いられる携帯機としては、例えば特許文献１に記載の携帯機が知られている。この特許文献１に記載の携帯機も含め、車両の電子キーシステムに用いられる携帯機は通常、上記車両との間の無線通信を行うために必要な各種電子部品、例えばアンテナ等の設けられる回路基板の外周をケースにより覆うことで同回路基板を外部環境から保護する構造を有している。
特開２００２−３３９６０５号公報 Conventionally, as a portable device used in such an electronic key system, for example, a portable device described in Patent Document 1 is known. A portable device used for an electronic key system of a vehicle including the portable device described in Patent Document 1 is usually a circuit provided with various electronic components, such as an antenna, necessary for performing wireless communication with the vehicle.

JP 2002-339605 A

ところで、こうした携帯機にあっては、ユーザに好んで所持してもらうために高い意匠性を有することが望まれる傾向にある。ここで、携帯機に高い意匠性を持たせる方法としては、例えば金属メッキされた加飾部材を携帯機のケースの外周面に取り付ける、いわゆる金属加飾等を施すことによって携帯機に高級感を持たせるといった方法がある。 By the way, in such a portable device, there is a tendency that it is desired to have a high designability so that the user likes it and possesses it. Here, as a method of giving the portable device high design properties, for example, by attaching a metal-plated decoration member to the outer peripheral surface of the case of the portable device, so-called metal decoration or the like, a high-quality feeling is given to the portable device. There is a way to have it.

一方、こうした加飾部材を携帯機のケースに取り付ける方法としては、例えば適宜の接着剤により接着するといった方法や、ねじ等の締結部材により締結するといった方法等、種々の固定方法が考えられる。ただし、加飾部材を携帯機のケースに取り付ける方法として接着剤により接着する方法を採用するようにした場合には、加飾部材を携帯機のケースに固定する際に位置ずれが生じ易いため、ケースの所定の取り付け位置に加飾部材を正確に取り付けようとすると、その作業が煩雑となるおそれがある。一方、加飾部材を携帯機のケースに取り付ける方法としてねじ等の締結部材により締結する方法を採用するようにした場合には、加飾部材のねじの挿入される穴の位置と、携帯機のねじの挿入される穴の位置とを合わせて、この状態を保持した状態でねじを挿入し締め付ける必要がある。したがって、加飾部材のねじの挿入される穴の位置と、携帯機のねじの挿入される穴の位置とを正確に合わせる作業が必要となるため、上記接着剤により接着する方法と同様、加飾部材をケースに取り付ける作業が煩雑となるおそれがある。 On the other hand, as a method of attaching such a decorative member to the case of the portable device, various fixing methods such as a method of bonding with an appropriate adhesive and a method of fastening with a fastening member such as a screw can be considered. However, when the method of attaching the decorative member to the case of the portable device is adopted as a method of attaching the decorative member to the case of the portable device, the positional deviation is likely to occur when fixing the decorative member to the case of the portable device. If the decoration member is to be accurately attached to a predetermined attachment position of the case, the operation may become complicated. On the other hand, when a method of fastening with a fastening member such as a screw is adopted as a method of attaching the decorative member to the case of the portable device, the position of the hole into which the screw of the decorative member is inserted, It is necessary to match the position of the hole into which the screw is inserted and insert and tighten the screw while maintaining this state. Accordingly, it is necessary to accurately match the position of the hole into which the screw of the decorative member is inserted and the position of the hole into which the screw of the portable device is inserted. The operation of attaching the decorative member to the case may be complicated.

なお、このような課題は、車両の電子キーシステムに用いられる携帯機に限らず、例えば住宅の居住者が携帯機を所持した状態で玄関ドアに接近したときに玄関ドアのアンロックを自動的に実行する住宅の電子キーシステムなど、各種の無線通信システムに用いられる携帯機にも同様に発生し得る。 Such a problem is not limited to the portable device used in the electronic key system of the vehicle. For example, when the resident of the house approaches the entrance door while holding the portable device, the unlocking of the entrance door is automatically performed. It can also occur in portable devices used in various wireless communication systems, such as a residential electronic key system.

本発明は、こうした実情に鑑みてなされたものであり、その目的は、意匠性を高めるためにケースに加飾を施す場合であれ、加飾部材をケースの所定の位置に容易に固定することのできる携帯機を提供することにある。 The present invention has been made in view of such circumstances, and the purpose thereof is to easily fix a decorative member at a predetermined position of the case, even when the case is decorated to enhance design. It is to provide a portable device that can be used.

上記課題を解決するために、請求項１に記載の発明は、搭載される各種部品を外部環境から保護する直方体状のケースと、該ケースを加飾するために同ケースの外周面に固定される加飾部材とを備え、特定の通信対象との間で無線通信を行う携帯機であって、前記加飾部材は、前記ケースの一辺を構成する部分に沿って延設される板状の部材からなり、その延設方向の一方の端部に前記ケースと当接する面からその反対側の面に貫通する貫通孔を有するとともに、その延設方向の他方の端部に鈎状の凸部を有し、同加飾部材が、２つを一組として、前記ケースの厚さ方向の互いに反対側に位置する２つの面に同ケースを挟んで互いに対向する位置にそれぞれ配設され、前記ケースは、前記一組の加飾部材のそれぞれの凸部が嵌合する鈎状の凹部を有するとともに、前記一組の加飾部材のそれぞれの貫通孔から挿入される一組の雄ねじが共に螺入される雌ねじの螺刻された雌ねじ部材を有し、前記一組の雄ねじが前記雌ねじ部材を共有して同雌ねじ部材の雌ねじ孔にそれぞれ螺入されることにより前記ケースに前記一組の加飾部材が締結固定されることを要旨としている。 In order to solve the above problems, the invention described in claim 1 is a rectangular parallelepiped case for protecting various components to be mounted from the external environment, and is fixed to the outer peripheral surface of the case for decorating the case. A decorating member that performs wireless communication with a specific communication target, wherein the decorating member is a plate-like member that extends along a portion that constitutes one side of the case . It is made of a member and has a through-hole penetrating from the surface in contact with the case to the opposite surface at one end in the extending direction, and a hook-shaped convex portion at the other end in the extending direction The decorative members are arranged in positions facing each other with the case sandwiched between two surfaces located on opposite sides of the case in the thickness direction, with the two decorative members as a set, case, hook-shaped concave that each of the convex portions of the pair of decorative member is fitted And a female screw member in which a set of male screws inserted from the respective through holes of the set of decorative members is screwed together, and the set of male screws is the female screw. The gist is that the set of decorative members is fastened and fixed to the case by sharing the members and screwing them into the female screw holes of the female screw member .

同構成によれば、ケースの外周面に加飾部材を取り付ける際に、ケースの凹部に加飾部材の凸部を嵌合させることで、加飾部材をケースの外周面の所定の位置に位置決めすることができるようになる。したがって、このように加飾部材を所定の位置に位置決めした後にこれをケースに固定するようにすれば、加飾部材をケースの外周面の所定の位置に容易に固定することができるようになる。 According to this configuration, when attaching the decorative member to the outer peripheral surface of the case, the decorative member is positioned at a predetermined position on the outer peripheral surface of the case by fitting the convex portion of the decorative member into the concave portion of the case. Will be able to. Therefore, if the decorative member is positioned at a predetermined position and then fixed to the case, the decorative member can be easily fixed at a predetermined position on the outer peripheral surface of the case. .

また、加飾部材の凸部をケースの凹部に嵌合した際に、これらが引っ掛かるかたちで嵌合するようになるため、加飾部材の位置が所定の位置に位置決めされた状態を保持することができるようになる。このため、加飾部材をケースの外周面の所定の位置に、より容易に固定することができるようになる。 Moreover , when the convex part of the decorating member is fitted into the concave part of the case, it will be fitted in the form of being caught, so that the position of the decorating member is kept in a predetermined position. Will be able to. For this reason, a decorating member can be more easily fixed to the predetermined position of the outer peripheral surface of a case.

さらに、ケースの外周面に加飾部材を固定する構造によって加飾部材の一方の端部が固定されるとともに、上記鈎状の凸部と同じく鈎状の凹部とからなる凹凸嵌合構造によって加飾部材の他方の端部が固定されるようになる。すなわち、これらの構造によって加飾部材の両端部が固定されるようになるため、加飾部材をケースに固定する効果を十分に確保することができるようになる。 Further , one end of the decorative member is fixed by a structure in which the decorative member is fixed to the outer peripheral surface of the case, and the concave and convex fitting structure including the bowl-shaped convex portion and the bowl-shaped concave portion is added. The other end of the decorative member is fixed. That is, since both ends of the decorative member are fixed by these structures, the effect of fixing the decorative member to the case can be sufficiently ensured.

一方、加飾部材の設けられる携帯機にあっては、ユーザが自身の好みに応じて加飾部材を取り替えることが考えられるため、加飾部材をケースに脱着可能に固定することが望ましい。また、こうした加飾部材の取り替えが繰り返し行われた場合であってもケースに加飾部材を確実に固定することができるように、加飾部材をケースに固定する構造が十分な耐久性を有している必要がある。この点、上記構成によるように、こうした加飾部材をケースに固定する構造を、雄ねじ及び雌ねじ部材といった締結構造により構成するようにすれば、加飾部材をケースに脱着可能に固定することができるようになるとともに、十分な耐久性を得ることもできるようになる。 On the other hand, in a portable device provided with a decoration member, it is conceivable that the user can replace the decoration member according to his / her preference. Therefore, it is desirable that the decoration member is detachably fixed to the case. In addition, the structure for fixing the decorative member to the case has sufficient durability so that the decorative member can be securely fixed to the case even when such replacement of the decorative member is repeated. Need to be. In this respect, such as by the above configuration, the structure for fixing such a decorative member to the case, if so configured by fastening structures such as male screw and the female screw member, to be removably secured to decorative member to the case As well as being able to do so, sufficient durability can be obtained.

ところで、加飾部材をケースに固定する構造を、雄ねじ及び雌ねじ部材といった締結構造により構成することで、加飾部材をケースに脱着可能に固定することができるようになるとともに、十分な耐久性を得ることも確かにできるようにはなる。ただし、携帯機に取り付ける加飾部材の大きさや数量等に応じて加飾部材を固定するために必要な締結構造の数が異なるため、例えば必要な締結構造の数が多くなると携帯機に設けられる雄ねじや雌ねじ部材の数も多くなることから、携帯機としての部品点数が増加し、ひいては携帯機の大型化を招くおそれがある。この点、上記構成によるように、ケースの厚さ方向の互いに反対側に位置する面に一組の加飾部材をそれぞれ配設するとともに、これら一組の加飾部材をケースにそれぞれ締結するための一組の雄ねじを、一つの雌ねじ部材の雌ねじ孔にそれぞれ反対側から螺入するようにすれば、一組の雄ねじに対してそれぞれ雌ねじ部材を用意する場合、すなわち２つの雌ねじ部材を用意する場合と比較して、一つの雌ねじ部材を割愛することができるようになる。このため、加飾部材をケースに固定する構造として上述のような雄ねじと雌ねじ部材とからなる締結構造を採用しつつも、携帯機としての部品点数の増加を最小限に抑えることができ、ひいては携帯機の大型化を回避することができるようになる。 Meanwhile, the structure for fixing the decorative member to the case, by constituting a fastening structure such male screw and the female screw member, along with it is possible to detachably secure the decorative member to the case, durable enough You will certainly be able to get However, since the number of fastening structures necessary for fixing the decorative member varies depending on the size and quantity of the decorative member attached to the portable device, for example, the number of the necessary fastening structures is increased in the portable device. Since the number of male screws and female screw members also increases, the number of parts as a portable device increases, which may result in an increase in the size of the portable device. In this regard, as in the above-described configuration, a set of decorative members is disposed on the surfaces positioned on opposite sides of the case in the thickness direction, and the set of decorative members is fastened to the case, respectively. When one set of male screws is screwed into the female screw hole of one female screw member from the opposite side, a female screw member is prepared for each set of male screws, that is, two female screw members are prepared. Compared to the case, one female screw member can be omitted. For this reason, while adopting the fastening structure consisting of the male screw and female screw member as described above as a structure for fixing the decorative member to the case, the increase in the number of parts as a portable device can be minimized, and consequently An increase in the size of the portable device can be avoided.

本発明にかかる携帯機によれば、意匠性を高めるためにケースに加飾を施す場合であれ、加飾部材をケースの所定の位置に容易に固定することができるようになる。 According to the portable device according to the present invention, the decoration member can be easily fixed at a predetermined position of the case, even when the case is decorated to enhance the design.

同図３（ａ），（ｂ）に示されるように、加飾部材３０ａは、基本的には、図中の上下方向に延びるかたちにて板状に形成されており、その正面部の上側の部分に、下側の部分や中央の部分よりも板厚の厚く形成された段差部３３が設けられている。そして、この加飾部材３０ａでは、この段差部３３がケース１０の切り欠き部１２の正面部を塞ぐ部分となるとともに、加飾部材３０ａの正面部の段差部３３を除く部分が上記ケース１０の段差部１４ａに当接する部分となる。また、この段差部３３の下端部に形成される段差面３３ａには、上記ケース１０の凹部１８ａの形状と同様の形状、すなわち鈎状に形成された凸部３１が設けられており、この加飾部材３０ａでは、この凸部３１が、上記ケース１０の凹部１８ａに嵌合する部分となる。さらに、この加飾部材３０ａの下端部には、上記ケース１０の貫通孔１６の位置に対応して、上記雄ねじ５０を挿入するための貫通孔３２が形成されている。ちなみに、この貫通孔３２の加飾部材３０ａの背面部側の開口端部には、上記雄ねじ５０の頭の部分の外径の大きさに対応した内径を有する大径部３２ａが形成されており、この加飾部材３０ａでは、雄ねじ５０が貫通孔３２に挿入された際に、雄ねじ５０の頭の部分がこの貫通孔３２の大径部３２ａに収容される。 As shown in FIGS. 3 (a) and 3 (b), the decorative member 30a is basically formed in a plate shape extending in the vertical direction in the figure, and above the front portion thereof. In this portion, a stepped portion 33 is formed which is formed thicker than the lower portion and the central portion. And in this decorating member 30a, while this level | step-difference part 33 becomes a part which plugs up the front part of the notch part 12 of the case 10, the part except the level | step-difference part 33 of the front part of the decorating member 30a is a part of the said case 10. It becomes a part which contacts the level | step-difference part 14a. Further, the step surface 33a formed at the lower end portion of the step portion 33 is provided with a convex portion 31 having a shape similar to the shape of the concave portion 18a of the case 10, that is, a bowl shape. In the decorative member 30 a, the convex portion 31 is a portion that fits into the concave portion 18 a of the case 10. Furthermore, a through hole 32 for inserting the male screw 50 is formed at the lower end portion of the decorative member 30a corresponding to the position of the through hole 16 of the case 10. Incidentally, a large-diameter portion 32a having an inner diameter corresponding to the outer diameter of the head portion of the male screw 50 is formed at the opening end of the through hole 32 on the back surface side of the decorative member 30a. In the decorative member 30 a, when the male screw 50 is inserted into the through hole 32, the head portion of the male screw 50 is accommodated in the large diameter portion 32 a of the through hole 32.

次に、図４（ａ），（ｂ）を参照して、加飾部材４０ａの構造について詳細に説明する。ここで、図４（ａ）は、加飾部材４０ａの正面構造を、また、図４（ｂ）は、同図４（ａ）のＤ−Ｄ線に沿った断面構造をそれぞれ示したものである。 Next, the structure of the decorating member 40a will be described in detail with reference to FIGS. 4 (a) and 4 (b). Here, FIG. 4A shows the front structure of the decorative member 40a, and FIG. 4B shows the cross-sectional structure along the line DD in FIG. 4A. is there.

同図４（ａ），（ｂ）に示されるように、加飾部材４０ａも、基本的には、図中の上下方向に延びるかたちにて板状に形成されており、その正面部の上端部に、上記加飾部材３０ａの凸部３１と同様の形状、すなわち鈎状に形成された凸部４１が設けられている。そして、この加飾部材４０ａでは、この凸部４１が、上記ケース１０の凹部１８ａに嵌合する部分となる。また、加飾部材４０ａの下端部にも、上記ケース１０の貫通孔１９の位置に対応して、上記雄ねじ５０を挿入するための貫通孔４２が形成されている。ちなみに、この貫通孔４２の加飾部材４０ａの背面部側の開口端部にも、上記雄ねじ５０の頭の部分の外径の大きさに対応した内径を有する大径部４２ａが形成されており、この加飾部材４０ａでも、雄ねじ５０が貫通孔４２に挿入された際に、雄ねじ５０の頭の部分がこの貫通孔４２の大径部４２ａに収容される。 4 (a) and 4 (b), the decorative member 40a is also basically formed in a plate shape extending in the vertical direction in the figure, and the upper end of the front portion thereof. The convex part 41 formed in the shape similar to the convex part 31 of the said decorating member 30a, ie, the hook shape, is provided in the part. And in this decorating member 40a, this convex part 41 turns into a part fitted to the recessed part 18a of the said case 10. FIG. A through hole 42 for inserting the male screw 50 is also formed at the lower end of the decorative member 40a corresponding to the position of the through hole 19 of the case 10. Incidentally, a large-diameter portion 42a having an inner diameter corresponding to the outer diameter of the head portion of the male screw 50 is also formed at the opening end of the through hole 42 on the back side of the decorative member 40a. Even in the decorative member 40 a, when the male screw 50 is inserted into the through hole 42, the head portion of the male screw 50 is accommodated in the large diameter portion 42 a of the through hole 42.

次に、図５（ａ）〜（ｄ）を参照して、こうした加飾部材３０ａ，３０ｂ，４０ａ，４０ｂの上記ケース１０への取り付け方法について詳細に説明する。なお、これら加飾部材３０ａ，３０ｂ，４０ａ，４０ｂの上記ケース１０への取り付け方法についてはそれぞれほぼ同様であるため、ここでは加飾部材３０ａの取り付け方法についてのみ説明し、加飾部材３０ｂ，４０ａ，４０ｂについてはこれと同様のものとして割愛する。 Next, with reference to FIGS. 5A to 5D, a method for attaching the decorative members 30a, 30b, 40a, and 40b to the case 10 will be described in detail. In addition, since it is substantially the same about the attachment method to the said case 10 of these decorating members 30a, 30b, 40a, and 40b, respectively, only the attachment method of the decorating member 30a is demonstrated here and the decorating members 30b and 40a are demonstrated. , 40b will be omitted as the same thing.

加飾部材３０ａをケース１０に取り付けるにあたっては、まず、図５（ａ）に示すように、その準備として加飾部材３０ａの凸部３１を、ケース１０の上方から凹部１５ａに嵌合する。これにより、図５（ｂ）に示すように、加飾部材３０ａの貫通孔３２の中心軸とケース１０の貫通孔１６の中心軸とが互いに一致する位置に加飾部材３０ａが位置決めされるとともに、加飾部材３０ａの凸部３１がケース１０の凹部１５ａに引っ掛かるかたちで嵌合することで加飾部材３０ａの位置が図中に示す位置に保持される。したがって、雄ねじ５０を加飾部材３０ａの貫通孔３２の側からケース１０の貫通孔１６に容易に挿入することができるようになる。そして、図５（ｃ）に示すように、この雄ねじ５０をケース１０の雌ねじ部材６１の雌ねじ孔６１ａに螺入することで、加飾部材３０ａがケース１０の段差部１４ａに固定される。同様に、図５（ｄ）に示すように、雄ねじ５０を加飾部材３０ｂの挿入孔３４の側からケース１０の貫通孔１６に挿入して雌ねじ部材６１の雌ねじ孔６１ａに反対側から螺入することで、加飾部材３０ｂがケース１０の段差部１４ｂに固定される。 In attaching the decorating member 30a to the case 10, first, as shown in FIG. 5A, the convex portion 31 of the decorating member 30a is fitted into the concave portion 15a from above the case 10 as preparation. As a result, as shown in FIG. 5B, the decoration member 30a is positioned at a position where the central axis of the through hole 32 of the decoration member 30a and the central axis of the through hole 16 of the case 10 coincide with each other. The position of the decorating member 30a is held at the position shown in the figure by fitting the convex portion 31 of the decorating member 30a so as to be caught in the concave portion 15a of the case 10. Therefore, the male screw 50 can be easily inserted into the through hole 16 of the case 10 from the through hole 32 side of the decorative member 30a. Then, as shown in FIG. 5C, the decorative member 30 a is fixed to the stepped portion 14 a of the case 10 by screwing the male screw 50 into the female screw hole 61 a of the female screw member 61 of the case 10. Similarly, as shown in FIG. 5D, the male screw 50 is inserted into the through hole 16 of the case 10 from the insertion hole 34 side of the decorative member 30b and screwed into the female screw hole 61a of the female screw member 61 from the opposite side. By doing so, the decorative member 30 b is fixed to the stepped portion 14 b of the case 10.

携帯機としてのこうした構成によれば、ケース１０の段差部１４ａに加飾部材３０ａを取り付ける際に、加飾部材３０ａの凸部３１とケース１０の凹部１５ａとからなる凹凸嵌合構造により、加飾部材３０ａの貫通孔３２の中心軸とケース１０の貫通孔１６の中心軸とが互いに一致する位置に加飾部材３０ａを位置決めすることができる。これにより、雄ねじ５０の貫通孔１６への挿入、さらに雌ねじ部材６１の雌ねじ孔６１ａへの螺入が容易となるため、加飾部材３０ａをケース１０に容易に取り付けることが可能となる。また、加飾部材３０ｂ及びケース１０の段差部１４ｂにも同様の凹凸嵌合構造が設けられていることから、加飾部材３０ｂについても、同様に、ケース１０に容易に取り付けることが可能となる。また、加飾部材３０ａ，３０ｂをケース１０の段差部１４ａに固定するための構造としてこうした凹凸嵌合構造を採用することで、例えば図６に示すように加飾部材３０ａ，３０ｂの上側の部分を雄ねじ７０と雌ねじ部材７１とからなる締結構造により締結固定するようにした携帯機と比較して、雄ねじ７０や雌ねじ部材７１のような部材を省略することができる。このため、携帯機としての部品点数の増加を回避することも可能となる。また、本実施形態にかかる携帯機のように、挿入孔１３のようなメカニカルキー２０を収容するための空間が形成されているために雌ねじ部材７１のような部材を設けるためのスペースを確保し難い携帯機であっても、加飾部材３０ａ，３０ｂを固定することが可能となる。ところで、図６に示すように加飾部材３０ａ，３０ｂの上側の部分を雄ねじ７０及び雌ねじ部材７１とからなる締結構造により固定するようにした携帯機にあっては、金属材料からなる雌ねじ部材６１，７１及び雄ねじ５０，７０を介して、同じく金属材料からなる加飾部材３０ａと加飾部材３０ｂとが互いに電気的に接続されるようになる。すなわち、携帯機に図中の一点鎖線で示すような金属体のループ形状が形成されるようになる。ここで、こうした金属体のループ形状の形成される部分に、例えば上述の車両側から送信されるリクエスト信号のような電波が進入しようとすると、この電波の進入を妨げる態様にて金属体のループ形状の形成される部分に誘導電流が生じる。このため、リクエスト信号がこの金属体のループ形状の形成される部分で遮蔽されてしまい、携帯機としてのリクエスト信号の受信感度が低下するおそれがある。この点、本実施形態にかかる携帯機にあっては、先の図５（ｄ）に示されるように、凹凸嵌合構造の設けられる部分では、加飾部材３０ａと加飾部材３０ｂとが電気的に接続されることがないため、こうした金属体のループ形状が形成されることを回避することができる。このため、携帯機に加飾部材３０ａ，３０ｂを固定するための構造を設けつつ、携帯機のリクエスト信号の受信感度をそのまま維持することができる。なお、この携帯機では、加飾部材４０ａについては同加飾部材４０ａの凸部４１とケース１０の凹部１８ａとからなる凹凸嵌合構造が、また、加飾部材４０ｂについてもこれと同様の凹凸嵌合構造がそれぞれ設けられている。このため、これら加飾部材４０ａ，４０ｂについても、同様に、これらをケース１０に容易に取り付けることができること、等々の効果が奏されることは言うまでもない。 According to such a configuration as a portable device, when the decorative member 30a is attached to the stepped portion 14a of the case 10, the concave / convex fitting structure including the convex portion 31 of the decorative member 30a and the concave portion 15a of the case 10 is added. The decorating member 30a can be positioned at a position where the central axis of the through hole 32 of the decorative member 30a and the central axis of the through hole 16 of the case 10 coincide with each other. This facilitates the insertion of the male screw 50 into the through hole 16 and the screwing of the female screw member 61 into the female screw hole 61a, so that the decorative member 30a can be easily attached to the case 10. Moreover, since the same uneven | corrugated fitting structure is provided also in the level difference part 14b of the decorating member 30b and the case 10, the decorating member 30b can also be easily attached to the case 10 similarly. . Further, by adopting such a concave-convex fitting structure as a structure for fixing the decorative members 30a, 30b to the stepped portion 14a of the case 10, for example, as shown in FIG. 6, the upper portions of the decorative members 30a, 30b Compared with a portable device that is fastened and fixed by a fastening structure including a male screw 70 and a female screw member 71, members such as the male screw 70 and the female screw member 71 can be omitted. For this reason, it is also possible to avoid an increase in the number of parts as a portable device. Moreover, since the space for accommodating the mechanical key 20 like the insertion hole 13 is formed like the portable machine concerning this embodiment, the space for providing members like the internal thread member 71 is ensured. Even if it is a difficult portable machine, the decorating members 30a and 30b can be fixed. Incidentally, as shown in FIG. 6, in a portable machine in which the upper portions of the decorative members 30a and 30b are fixed by a fastening structure including a male screw 70 and a female screw member 71, a female screw member 61 made of a metal material. , 71 and the male screws 50, 70, the decorative member 30a and the decorative member 30b, which are also made of a metal material, are electrically connected to each other. That is, a loop shape of a metal body as shown by a one-dot chain line in the figure is formed on the portable device. Here, when a radio wave such as a request signal transmitted from the vehicle side, for example, enters the portion where the loop shape of the metal body is formed, the loop of the metal body is prevented in a manner that prevents the radio wave from entering. An induced current is generated in the portion where the shape is formed. For this reason, the request signal is shielded by the portion where the loop shape of the metal body is formed, and there is a possibility that the reception sensitivity of the request signal as a portable device is lowered. In this regard, in the portable device according to the present embodiment, as shown in FIG. 5D, the decorative member 30a and the decorative member 30b are electrically connected to each other at the portion where the concave-convex fitting structure is provided. Therefore, it is possible to avoid the formation of the loop shape of the metal body. For this reason, it is possible to maintain the reception sensitivity of the request signal of the portable device as it is while providing a structure for fixing the decorative members 30a and 30b to the portable device. In this portable device, the decorative member 40a has an uneven fitting structure composed of the convex portion 41 of the decorative member 40a and the concave portion 18a of the case 10, and the decorative member 40b has the same unevenness. Each fitting structure is provided. For this reason, it cannot be overemphasized that these can also be easily attached to case 10 similarly about these decoration members 40a and 40b, and so on.

以上説明したように、本実施形態にかかる携帯機によれば、以下のような効果が得られるようになる。
（１）加飾部材３０ａに鈎状の凸部３１を設けるとともに、この凸部３１の嵌合する同じく鈎状の凹部１５ａをケース１０に設け、これらの凸部３１と凹部１５ａとにより凹凸嵌合構造を設けるようにした。これにより、ケース１０に加飾部材３０ａを取り付ける際に、ケース１０の凹部１５ａに加飾部材３０ａの凸部３１を嵌合させることで、加飾部材３０ａの雄ねじ５０の挿入される貫通孔３２の中心軸と、ケース１０の雄ねじ５０の挿入される貫通孔１６の中心軸とが一致する位置に加飾部材３０ａを位置決めすることができるようになる。また、加飾部材３０ａの凸部３１とケース１０の凹部１５ａとが引っ掛かるかたちで嵌合するため、加飾部材３０ａが位置決めされた状態を保持することもできるようになる。したがって、雄ねじ５０の貫通孔１６への挿入、さらに雌ねじ部材６１の雌ねじ孔６１ａへの螺入が容易となるため、加飾部材３０ａをケース１０の段差部１４ａに容易に固定することができるようになる。また、加飾部材３０ｂ、並びに加飾部材４０ａ，４０ｂについても、同様に、これらをケース１０の段差部１４ｂ、並びに段差部１７ａ，１７ｂに容易に固定することができる。 As described above, according to the portable device according to the present embodiment, the following effects can be obtained.
