Description

本発明は、筐体及び携帯機器の筐体並びにそれらの製造方法に関し、特に、防水機能を備える筐体及び携帯機器の筐体並びにそれらの製造方法に関する。   The present invention relates to a casing, a casing of a portable device, and a manufacturing method thereof, and particularly relates to a casing having a waterproof function, a casing of a portable device, and a manufacturing method thereof.

携帯電子端末、例えば、スマートフォンでは、タッチパネル上で入力操作を行う構造が主流である。また、操作時の持ちやすさを考慮すると、携帯電子端末の筐体の幅は50ｍｍ〜60ｍｍ位が望ましい。タッチパネルの見易さや入力操作の容易性向上を重視すると、タッチパネルの大画面化が臨まれるが、上述した筐体の望ましい幅がネックとなっている。   In a portable electronic terminal, for example, a smartphone, a structure in which an input operation is performed on a touch panel is mainstream. Further, considering the ease of holding during operation, the width of the casing of the portable electronic terminal is preferably about 50 mm to 60 mm. If emphasis is placed on improving the ease of viewing the touch panel and the ease of input operation, the touch panel becomes larger, but the desirable width of the casing described above is a bottleneck.

図１０は、関連する技術に関し、防水構造を有する携帯電子端末の筐体１０００の外観図である。図１１は、図１０に示した筐体１０００の中央部の横断面図である。図１１を参照すると、下部筐体部材２の端面と接する上部筐体部材１の端面上に、パッキン溝３が形成されている。上部と下部筐体部材１，２間に、保持部材５を掛けることにより、パッキン６はパッキン溝３に圧縮介装されて、上部と下部筐体部材１，２間を防水する。   FIG. 10 is an external view of a casing 1000 of a portable electronic terminal having a waterproof structure in relation to a related technique. FIG. 11 is a cross-sectional view of the central portion of the housing 1000 shown in FIG. Referring to FIG. 11, a packing groove 3 is formed on the end surface of the upper housing member 1 that contacts the end surface of the lower housing member 2. When the holding member 5 is hung between the upper and lower housing members 1 and 2, the packing 6 is compressed and interposed in the packing groove 3 to waterproof between the upper and lower housing members 1 and 2.

また、特許文献１には、表示部側筐体と操作部側筐体とによって囲まれた筐体内部に段差部を形成し、この段差部と、表部側筐体の内面との間に防水チューブを接着した折り畳み式携帯電話機が開示されている。   Further, in Patent Document 1, a step portion is formed inside a case surrounded by the display unit side case and the operation unit side case, and between the step portion and the inner surface of the front side case. A foldable mobile phone to which a waterproof tube is bonded is disclosed.

特許文献２の折り畳み式携帯電話機では、表示ユニットのリアカバー内面と、表示ユニットのベース部とが、両面テープで互いに接着されている。このベース部には、両面テープの接着箇所よりも筐体中央側の位置に溝が形成されている。この溝内に、チューブがしぼんだ状態で格納されている。筐体の分解時、このチューブ内には流体が注入されて膨張し、リアカバーの取り外しを助ける。したがって、このチューブは、防水用ではない。   In the foldable mobile phone of Patent Document 2, the inner surface of the rear cover of the display unit and the base portion of the display unit are bonded to each other with a double-sided tape. In the base portion, a groove is formed at a position closer to the center of the housing than the bonding location of the double-sided tape. In this groove, the tube is stored in a deflated state. When the housing is disassembled, fluid is injected into the tube and expands to help remove the rear cover. Therefore, this tube is not waterproof.

特許文献３には、カバー（上部筐体部材）内面と、ケース（下部筐体部材）の肉厚に形成された端面（ボディ外壁端面）との間に、ホットメルト接着剤を塗布し、塗布した接着剤を不活性ガスにより発泡性させて、弾力性を有するシール材と成す、ハードディスクが開示されている。カバーの端面は、ケースの外側に露出している。   In Patent Document 3, a hot melt adhesive is applied between the inner surface of the cover (upper housing member) and the end surface (end surface of the body outer wall) formed on the case (lower housing member). A hard disk is disclosed in which the adhesive is foamed with an inert gas to form an elastic sealing material. The end face of the cover is exposed outside the case.

以下の分析は、本発明によって与えられたものである。   The following analysis is given by the present invention.

図１１に示した防水構造によれば、筐体１０００の外壁にパッキン溝３を形成しているため、左右のパッキン溝壁７，８が必要となる。この結果、筐体外壁が肉厚となり、筐体幅が拡大され、筐体が持ちにくくなっている。また、パッキン６を圧縮状態で保持する保持部材５を要するため、さらに、筐体１０００の幅が広くなると共に、部品数が増加している。   According to the waterproof structure shown in FIG. 11, since the packing groove 3 is formed on the outer wall of the housing 1000, the left and right packing groove walls 7 and 8 are necessary. As a result, the outer wall of the casing becomes thick, the casing width is increased, and the casing is difficult to hold. Further, since the holding member 5 that holds the packing 6 in a compressed state is required, the width of the casing 1000 is further increased and the number of components is increased.

特許文献１の防水構造によれば、段差部および防水チューブを筐体内部に配置することによって、筐体内部の空間が削減され、筐体の実質的な肉厚が厚くなり、結果として、携帯電話機の幅の拡大を招来してしまう。   According to the waterproof structure of Patent Document 1, by disposing the stepped portion and the waterproof tube inside the casing, the space inside the casing is reduced, and the substantial thickness of the casing is increased. This will increase the width of the phone.

特許文献２のチューブは、防水用ではない。なお、特許文献２のチューブは、両面テープの接着箇所よりも筐体内側に配置されることによって、筐体内部の空間を削減し、又、筐体の肉厚を実質的に厚くし、結果として、携帯電話機の幅の拡大を招来している。   The tube of Patent Document 2 is not waterproof. In addition, the tube of patent document 2 reduces the space inside a housing | casing by arrange | positioning inside a housing | casing rather than the adhesion | attachment location of a double-sided tape, Moreover, the thickness of a housing | casing is increased substantially, and the result As a result, the expansion of the width of mobile phones has been invited.

特許文献３のハードディスクによれば、カバー内面をボディ側に接着しているため、筐体内部の空間が削減され、又、カバー（上部筐体部材）の端面がケース（下部筐体部材）の外側に露出している等によって、筐体の実質的な肉厚が厚くなり、結果として、携帯電話機の幅の拡大を招来している。また、特許文献３のハードディスクによれば、カバー端面よりもカバー中心側に位置するカバー内面の部分を、ボディに接着しているため、カバー接着後は、カバーを開いて、ケース内部に内装部品を実装することが困難となる。   According to the hard disk of Patent Document 3, since the inner surface of the cover is bonded to the body side, the space inside the housing is reduced, and the end surface of the cover (upper housing member) is the case (lower housing member). Due to the exposure to the outside, the substantial thickness of the housing is increased, and as a result, the width of the mobile phone is increased. Further, according to the hard disk disclosed in Patent Document 3, the inner surface of the cover, which is located closer to the center of the cover than the end surface of the cover, is bonded to the body. It becomes difficult to implement.

かくして、筐体の幅の削減に寄与するダウンサイズされた防水構造の提供と、内装部品の実装の容易化が望まれている。   Thus, it is desired to provide a downsized waterproof structure that contributes to a reduction in the width of the housing and to facilitate the mounting of interior parts.

本発明は、第１の視点において、少なくとも第１および第２の筐体部材と、前記第１および第２の筐体部材の対向する両端面にそれぞれ接着し、前記第１および第２の筐体部材を接合すると共に前記第１および第２の筐体部材の間を防水する、伸縮自在な弾性体と、を有する筐体を提供する。   In the first aspect of the present invention, the first and second casing members are bonded to at least the first and second casing members and opposite end faces of the first and second casing members, respectively. There is provided a casing having a stretchable elastic body that joins body members and waterproofs between the first and second casing members.

There is provided a method for manufacturing a housing, wherein at least a part or all of the outer wall of the housing is constructed by at least the first and second housing members and the elastic body that can be expanded and contracted.

本発明は、第３の視点において、第１および第２の筐体部材の対向する両端面間に接着された弾性体が伸びることを利用して、前記第１の筐体部材を前記第２の筐体部材に対して相対的に変位させた状態で、前記筐体の前記第１および第２の筐体部材によって囲まれる内部に、携帯機器の内装部材を挿入する工程を含む、携帯機器の製造方法を提供する。   According to a third aspect of the present invention, in the third aspect, the first casing member is moved to the second position by utilizing the extension of the elastic body bonded between the opposite end faces of the first and second casing members. A portable device including a step of inserting an interior member of the portable device into the inside of the housing surrounded by the first and second housing members in a state of being relatively displaced with respect to the housing member A manufacturing method is provided.

第１〜３の視点は、筐体の幅の削減に寄与するダウンサイズされた防水構造の提供と、内装部品の実装の容易化に貢献する。   The first to third viewpoints contribute to the provision of a downsized waterproof structure that contributes to the reduction of the width of the housing and the facilitation of mounting of the interior parts.

本発明の一実施形態の概要について、図面を参照して説明する。なお、この概要に付記した図面参照符号は、理解を助けるための一例として各要素に便宜上付記したものであり、本発明を図示の態様に限定することを意図するものではない。   An outline of an embodiment of the present invention will be described with reference to the drawings. Note that the reference numerals of the drawings attached to this summary are attached to the respective elements for convenience as an example for facilitating understanding, and are not intended to limit the present invention to the illustrated embodiment.

図２を参照すると、第１および第２の筐体部材１１，１２の対向する両端面１１ａ，１２ａに、弾性体２１がそれぞれ接着している。弾性体２１によって、第１および第２の筐体部材１１，１２が一体化された筒型の筐体１０が形成される。筐体１０の外壁の少なくとも一部分は、第１および第２の筐体部材１１，１２並びに弾性体２１によって構築されている。なお、筐体１０の外壁の全部を、第１および第２の筐体部材１１，１２並びに弾性体２１によって構築することもできる。   Referring to FIG. 2, elastic bodies 21 are bonded to the opposite end faces 11 a and 12 a of the first and second casing members 11 and 12, respectively. The elastic body 21 forms a cylindrical casing 10 in which the first and second casing members 11 and 12 are integrated. At least a part of the outer wall of the housing 10 is constructed by the first and second housing members 11 and 12 and the elastic body 21. Note that the entire outer wall of the housing 10 can also be constructed by the first and second housing members 11, 12 and the elastic body 21.

弾性体２１は、自然状態、すなわち、非圧縮かつ非伸長状態で、第１および第２の筐体部材１１，１２を接合している。このように、弾性体２１を伸縮自在な状態で存在させるため、両端面１１ａ，１２ａ上には、弾性体２１を圧縮介装するための溝が形成されず、両端面１１ａ，１２ａは平坦である。このため、筐体１０の肉厚を薄くすることができ、この結果、筐体１０の幅を小さくすることができる。また、筐体１０は、複数の筐体部材１１，１２を挟みこんで弾性体２１を圧縮するための部材を有さないため、さらに筐体１０の幅は狭くなっており、加えて、筐体１０の構成部品数も削減されている。   The elastic body 21 joins the first and second casing members 11 and 12 in a natural state, that is, in a non-compressed and non-extended state. Thus, since the elastic body 21 exists in a stretchable state, no groove for compressing and interposing the elastic body 21 is formed on the both end faces 11a and 12a, and the both end faces 11a and 12a are flat. is there. For this reason, the wall thickness of the housing | casing 10 can be made thin, As a result, the width | variety of the housing | casing 10 can be made small. Further, since the casing 10 does not have a member for compressing the elastic body 21 with the plurality of casing members 11 and 12 sandwiched therebetween, the width of the casing 10 is further narrowed. The number of components of the body 10 is also reduced.

弾性体２１が、伸縮自在な状態で、両端面１１ａ，１２ａ同士を接合していることによって、下記の利点が生じる。すなわち、筐体１０内に、内装部材を実装する際、例えば、弾性体２１が伸びることを利用して、第１の筐体部材１１を第２の筐体部材１２に対して相対的に変位させて、筐体１０の開口部ないし内部スペースを筐体１０の厚み方向に拡げて、図５に示すような内装部品３５の筐体１０内への挿入を容易化することができる。   The following advantages are produced by joining the both end faces 11a and 12a in a state where the elastic body 21 is stretchable. That is, when the interior member is mounted in the housing 10, the first housing member 11 is displaced relative to the second housing member 12 by utilizing, for example, the elastic body 21 extending. Thus, the opening or internal space of the housing 10 can be expanded in the thickness direction of the housing 10 to facilitate the insertion of the interior part 35 into the housing 10 as shown in FIG.

要約すると、第１および第２の筐体部材１１，１２を接合している弾性体２１は、複数の筐体部材１１，１２間を防水すると共に、弾性体２１が伸びることによって、筐体１０と筐体１０内に実装される内装部品３５との厚み方向の干渉を回避させる機能も発揮する。   In summary, the elastic body 21 that joins the first and second casing members 11 and 12 waterproofs the plurality of casing members 11 and 12, and the elastic body 21 extends to expand the casing 10. And the function of avoiding interference in the thickness direction between the interior part 35 mounted in the housing 10.

また、図７を参照して、弾性体２１に切欠き２１４を形成した場合、弾性体がさらに変形しやすくなって、第１と第２の筐体部材１１，１２の間隔を拡げやすくなり、筐体内に嵩高な内装部品を実装することがさらに容易となる。   In addition, referring to FIG. 7, when the notch 214 is formed in the elastic body 21, the elastic body is further easily deformed, and the interval between the first and second casing members 11 and 12 is easily increased. It becomes easier to mount bulky interior parts in the housing.

また、筒型構造の弾性体中継部において、複数の筐体部材間に非接着部を設けることにより、換言すると、図８を参照して、弾性体２２と、第１および第２の筐体部材１１，１２の少なくともいずれか一方との間に、非接着部２２ｃを設けることによって、筐体１０の伸縮量を増加させることができる。   Further, in the elastic-body relay portion having a cylindrical structure, by providing a non-adhesive portion between a plurality of housing members, in other words, referring to FIG. 8, the elastic body 22 and the first and second housings By providing the non-adhesive portion 22c between at least one of the members 11 and 12, the amount of expansion and contraction of the housing 10 can be increased.

好ましい実施形態によれば、筐体は、上部と下部筐体部材の端面同士を中継する部分に弾性体が接着され、複数部材が一体化された筒型の筐体構造を有する。   According to a preferred embodiment, the housing has a cylindrical housing structure in which an elastic body is bonded to a portion that relays the end surfaces of the upper and lower housing members, and a plurality of members are integrated.

本発明は、防水性能を要求される携帯機器ないし携帯電子機器全般に好適に適用され、例えば、携帯電話、スマートフォン、ゲーム機、タブレットＰＣ(Personal Computer)、ノートＰＣ、ＰＤＡ(Personal Data Assistants：携帯情報端末)、デジタルカメラ等に好適に適用される。   INDUSTRIAL APPLICABILITY The present invention is preferably applied to portable devices or portable electronic devices that require waterproof performance. For example, mobile phones, smartphones, game machines, tablet PCs (Personal Computers), notebook PCs, PDAs (Personal Data Assistants: mobile phones). It is suitably applied to information terminals) and digital cameras.

続いて、本発明の一実施形態について図面を参照して詳細に説明する。なお、以降の記述において、多くの具体的事項は、説明のため、本発明の理解を助けるためになされたものである。   Next, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, many specific items are made for the purpose of explanation and to help understanding of the present invention.

（実施形態１）
図１は、実施形態１に係る筐体の分解図である。図２は、図１に示した筐体中央部を幅方向に切断した面を示す横断面図である。図３は、図１に示した筐体の一側開口部を示す部分図である。図４は、図１に示した筐体の他側開口部を示す部分図である。 (Embodiment 1)
FIG. 1 is an exploded view of a housing according to the first embodiment. FIG. 2 is a cross-sectional view showing a surface obtained by cutting the central portion of the housing shown in FIG. 1 in the width direction. FIG. 3 is a partial view showing one side opening of the housing shown in FIG. FIG. 4 is a partial view showing the other side opening of the housing shown in FIG.

図１および図２を参照すると、上部および下部筐体部材（第１および第２の筐体部材）１１，１２の対向する両端面１１ａ，１２ａに、弾性体２１がそれぞれ接着している。   Referring to FIGS. 1 and 2, the elastic bodies 21 are bonded to the opposite end faces 11 a and 12 a of the upper and lower casing members (first and second casing members) 11 and 12, respectively.

筒状の筐体１０の製造方法の一例を説明すると、弾性体２１は、上部および下部筐体部材１１，１２の対向する両端面１１ａ，１２ａ間に、接着後に弾性体２１となる接着剤を接着することにより形成される。例えば、上部および下部筐体部材１１，１２を対向した状態で金型にセットし、弾性体２１となる接着剤を両端面１１ａ，１２ａ間に注入することにより、上部および下部筐体部材１１，１２を一体化することができる。   An example of the manufacturing method of the cylindrical housing 10 will be described. The elastic body 21 is formed by applying an adhesive that becomes the elastic body 21 after bonding between the opposite end faces 11a, 12a of the upper and lower housing members 11, 12. It is formed by bonding. For example, the upper and lower casing members 11 and 12 are set in a mold facing each other, and an adhesive to be an elastic body 21 is injected between the both end faces 11a and 12a. 12 can be integrated.

上部および下部筐体１１，１２は、プラスチック樹脂、例えば、ＰＣ樹脂（ポリカーボネイト樹脂）を材料として、金型成形することができる。硬化後、弾性体２１となる接着剤には、例えば、ＰＣ樹脂と接着可能な、選択接着性シリコーンゴムを用いることができる。   The upper and lower housings 11 and 12 can be molded using a plastic resin, for example, a PC resin (polycarbonate resin). For the adhesive that becomes the elastic body 21 after curing, for example, a selective adhesive silicone rubber that can be bonded to a PC resin can be used.

なお、上部および下部筐体１１，１２などの筐体部材の素材として、ＰＣ樹脂を例示したが、筐体部材の素材として、金属を用いてもよい。金属の場合、選択接着シリコーンゴムの接着部には、プライマー処理をすることが好ましい。筐体部材を金属製にすることで、強度が向上するため、筐体１０のサイズを更に削減可能である。また、複数の筐体部材間を接着する弾性体の素材は、選択接着性シリコーンゴムに限定されず、筐体部材に接着して弾性体となるものであればよい。   In addition, although PC resin was illustrated as a raw material of housing members, such as the upper and lower housings 11 and 12, a metal may be used as a material of the housing member. In the case of a metal, it is preferable to perform primer treatment on the bonded portion of the selectively bonded silicone rubber. Since the strength is improved by making the casing member made of metal, the size of the casing 10 can be further reduced. The material of the elastic body that bonds the plurality of housing members is not limited to the selective adhesive silicone rubber, and any material that adheres to the housing member and becomes an elastic body may be used.

下部筐体１２を一部品として示したが、下部筐体１２を複数部品から構成してもよく、これら複数部品の間をゴム接着してもよい。上部筐体部材１１等についても同様である。   Although the lower housing 12 is shown as one component, the lower housing 12 may be composed of a plurality of components, and the plurality of components may be bonded with rubber. The same applies to the upper casing member 11 and the like.

両端面１１ａ，１２ａは、筐体１０の長手方向に延在しかつ筐体１０の上下ないし厚み方向に対向する端面である。筐体１０の外壁のうち左右の側壁が、第１および第２の筐体部材１１，１２並びに弾性体２１によって構築されている。弾性体２１によって、上部および下部筐体部材１１，１２が一体化された筒型の筐体１０が形成されている。   Both end surfaces 11 a and 12 a are end surfaces that extend in the longitudinal direction of the housing 10 and face the top and bottom or the thickness direction of the housing 10. The left and right side walls of the outer wall of the housing 10 are constructed by the first and second housing members 11 and 12 and the elastic body 21. The elastic body 21 forms a cylindrical housing 10 in which the upper and lower housing members 11 and 12 are integrated.

上部筐体部材１１の上部には、両面テープ１３によって、表示窓（カバー）３１が接着されている。上部および下部筐体部１１，１２並びに表示窓３１によって囲まれた、筐体１０内の空間には、例えば、筐体１０が携帯機器用である場合、基板、表示画面などの各種内装部品３２，３３，３４が実装される。   A display window (cover) 31 is bonded to the upper portion of the upper casing member 11 with a double-sided tape 13. In the space within the casing 10 surrounded by the upper and lower casing portions 11 and 12 and the display window 31, for example, when the casing 10 is for a portable device, various interior parts 32 such as a substrate and a display screen. , 33, 34 are implemented.

なお、筐体１０の分割位置、すなわち、上部筐体部材１１と下部筐体１２の接合位置は、図１に示した位置に限定されず、例えば、筐体１０の裏面又は筐体１０の正面の表示窓３１横に設けてもよい。また、本実施形態では、弾性体２１を、上下分割型の筐体１０に適用する例について説明しているが、弾性体２１は、左右分割型の筐体、或いは、一側又は両側が閉止された袋状ないし筒状の主筐体と蓋部材から主として構成される筐体にも適用可能である。   Note that the division position of the housing 10, that is, the joining position of the upper housing member 11 and the lower housing 12 is not limited to the position illustrated in FIG. 1, for example, the back surface of the housing 10 or the front surface of the housing 10. It may be provided beside the display window 31. In this embodiment, an example in which the elastic body 21 is applied to the upper and lower split type casing 10 is described. However, the elastic body 21 is closed to the left and right split type casing, or one side or both sides are closed. The present invention can also be applied to a casing mainly composed of a bag-shaped or cylindrical main casing and a lid member.

内装部品３２，３３，３４を、筒状の筐体１０を形成した後から筐体１０内に実装する際には、弾性体２１が伸びることを利用して、上部筐体部材１１を第２の筐体部材１２に対して相対的に変位させた状態で、筐体１０の第１および第２の筐体部材１１，１２によって囲まれる内部に、内装部材３２，３３，３４を挿入することができる。この方法は、後述するように、携帯機器の筐体１０内に、嵩高な内装部品、例えば、カメラユニットを実装する際、有利である。   When the interior parts 32, 33, 34 are mounted in the casing 10 after the cylindrical casing 10 is formed, the upper casing member 11 is moved to the second position by utilizing the extension of the elastic body 21. The interior members 32, 33, and 34 are inserted into the interior of the housing 10 surrounded by the first and second housing members 11 and 12 in a state of being relatively displaced with respect to the housing member 12. Can do. As will be described later, this method is advantageous when a bulky interior part, for example, a camera unit is mounted in the casing 10 of the portable device.

図１、図３および図４を参照すると、筐体１０の一側開口には、第１の防水蓋４１が嵌合される。筐体１０の一側開口縁には、筐体１０の上部および下部内面１１２，１２２と第１の防水蓋４１との間を防水するために、第１のパッキン部２１２が形成ないし設けられている。筐体１０の他側開口縁には、筐体１０の上部および下部内面１１２，１２２と第２の防水蓋４２の間を防水するために、第２のパッキン部２１３が形成ないし設けられている。なお、弾性体２１、第１および第２のパッキン部２１２，２１３は、接着後に伸縮自在な接着剤を用いて、一体的に形成することができる。図１に示した状態の筐体１０に、第１および第２の防水蓋４１，４２を嵌めることによって、筐体１０は完全に防水化される。   Referring to FIGS. 1, 3, and 4, a first waterproof lid 41 is fitted into one side opening of the housing 10. A first packing portion 212 is formed or provided at one side opening edge of the housing 10 in order to waterproof between the upper and lower inner surfaces 112 and 122 of the housing 10 and the first waterproof lid 41. Yes. A second packing portion 213 is formed or provided at the other opening edge of the housing 10 to waterproof between the upper and lower inner surfaces 112 and 122 of the housing 10 and the second waterproof lid 42. . The elastic body 21 and the first and second packing portions 212 and 213 can be integrally formed using an adhesive that can be expanded and contracted after bonding. By fitting the first and second waterproof lids 41 and 42 to the casing 10 in the state shown in FIG. 1, the casing 10 is completely waterproofed.

筐体１０の利点を以下に説明する。上部および下部筐体部材１１，１２の両端面１１ａ，１２ａを弾性体２１で接合することによって、防水機構が占有するスペースが最小化できる。筐体１０の外壁のうち、弾性体２１を含む部分の肉厚も、単純に筐体１０の肉厚と同じになり、筐体１０の肉厚のみで防水が達成できる。この結果、筐体１０の幅を削減できる。弾性体２１を圧縮状態に保持する必要がないため、圧縮状態を保持するための構造や部材が不要となり、筐体１０の構成部品数が削減できる。この結果、筐体１０の幅を削減できる。   The advantages of the housing 10 will be described below. By joining the both end faces 11a, 12a of the upper and lower casing members 11, 12 with the elastic body 21, the space occupied by the waterproof mechanism can be minimized. Of the outer wall of the casing 10, the thickness of the portion including the elastic body 21 is simply the same as the thickness of the casing 10, and waterproofing can be achieved only by the thickness of the casing 10. As a result, the width of the housing 10 can be reduced. Since it is not necessary to hold the elastic body 21 in a compressed state, a structure or member for holding the compressed state is not necessary, and the number of components of the housing 10 can be reduced. As a result, the width of the housing 10 can be reduced.

上部および下部筐体部材１１，１２を互いに接着して筒型の筐体１０を形成した後も、弾性体２１が伸縮自在であるため、筐体１０内で収容物を組立てることが容易となる。筒型の筐体１０が、分割された複数の筐体部材１１，１２等から構成されている。個々の筐体部材１１，１２等は、比較的単純な形状をしているため、金型を用いた製作が容易であり、筐体１０内面の形状に関する設計自由度が高い。第１ないし第２の防水蓋４１，４２用のパッキン部２１２，２１３と、弾性体２１を一体成形することが可能である。また、第１ないし第２の防水蓋４１，４２の構造も簡素化できる。   Even after the upper housing member 11 and the lower housing member 12 are bonded to each other to form the cylindrical housing 10, the elastic body 21 can be expanded and contracted, so that it is easy to assemble the contents in the housing 10. . A cylindrical casing 10 is composed of a plurality of divided casing members 11, 12 and the like. Since the individual casing members 11 and 12 have a relatively simple shape, they can be easily manufactured using a mold, and the degree of freedom in designing the shape of the inner surface of the casing 10 is high. The packing portions 212 and 213 for the first and second waterproof lids 41 and 42 and the elastic body 21 can be integrally formed. In addition, the structure of the first and second waterproof lids 41 and 42 can be simplified.

（実施形態２）
本実施形態２では、嵩高な内装部品を有する携帯機器、特に、カメラ付き携帯機器の製造方法、および、この携帯機器の筐体に好適な弾性体の形状について説明する。なお、本実施形態２と前記実施形態１の共通点に関しては、前記実施形態１の記載を適宜参照することができるものとし、以下、主として、実施形態２と実施形態１の相違点について説明する。 (Embodiment 2)
In the second embodiment, a manufacturing method of a mobile device having a bulky interior part, in particular, a camera-equipped mobile device, and a shape of an elastic body suitable for a casing of the mobile device will be described. In addition, regarding the common points of the second embodiment and the first embodiment, the description of the first embodiment can be referred to as appropriate. Hereinafter, differences between the second embodiment and the first embodiment will be mainly described. .

図５は、実施形態２に係る筐体の分解図である。図６は、図５に示した筐体の幅方向中央部を長手方向に切断した面を示す縦断面図である。図７は、図５に示した筐体の長手方向中央部を幅方向に切断した面を示す横断面図である。   FIG. 5 is an exploded view of the housing according to the second embodiment. FIG. 6 is a longitudinal sectional view showing a surface obtained by cutting the central portion in the width direction of the housing shown in FIG. 5 in the longitudinal direction. FIG. 7 is a cross-sectional view illustrating a surface obtained by cutting the longitudinal center portion of the housing illustrated in FIG. 5 in the width direction.

図５を参照すると、図５および図６を参照すると、上部および下部筐体部材１１，１２が弾性体２１で接合された筒状の筐体１０内の窪み１２３に、嵩高なカメラユニット３５が配置されている。   Referring to FIG. 5, referring to FIGS. 5 and 6, a bulky camera unit 35 is placed in a recess 123 in the cylindrical casing 10 in which the upper and lower casing members 11 and 12 are joined by the elastic body 21. Has been placed.

カメラユニット３５の実装時、筐体１０をそのままの状態で、筐体１０内にカメラユニット３５を挿入しようとすると、カメラユニット３５の突起は、筐体１０の開口部と干渉する。しかし、各種内装部品の高さにはバラツキがあり、カメラユニット３５の高さに合わせて、筐体１０の内部スペースの高さを設定し、筐体１０の体積の膨張を招くことは、効率的ではない。   When the camera unit 35 is mounted, if the camera unit 35 is inserted into the housing 10 with the housing 10 as it is, the projection of the camera unit 35 interferes with the opening of the housing 10. However, there are variations in the height of various interior parts, and it is efficient to set the height of the internal space of the housing 10 according to the height of the camera unit 35 and cause the volume of the housing 10 to expand. Not right.

そこで、弾性体２１が伸びることを利用して、例えば、上部筐体部材１１を上方へ引っ張ることにより、上部筐体部材１１を下部筐体部材１２に対して相対的に変位させて、筐体１０の開口部ないし筐体１０の内部空間を拡げた状態で、筐体１０内にカメラユニット３５を挿入していく。カメラユニット３５の突起が窪み１２３に位置した後、上記引っ張り操作を止めると、弾性体２１の復元力によって、上部筐体部材１１は元位置に復帰する。   Therefore, by utilizing the extension of the elastic body 21, for example, by pulling the upper casing member 11 upward, the upper casing member 11 is displaced relative to the lower casing member 12, and the casing The camera unit 35 is inserted into the housing 10 in a state where the opening of 10 or the internal space of the housing 10 is expanded. After the projection of the camera unit 35 is located in the recess 123, when the pulling operation is stopped, the upper housing member 11 returns to the original position by the restoring force of the elastic body 21.

好ましくは、図６および図７に示すように、弾性体２１に切欠き２１４を形成する。切欠き２１４は、上部および下部筐体部材の対向する両端面１１ａ，１２ａ間に位置する。切欠き２１４は、両端面１１ａ，１２ａに沿って延在している。切欠き２１４によって、弾性体２１は、凹形状を形成しており、特に、図７に示したように、コの字状ないしＵ字状の断面を有している。この断面の背部が筐体１０の外面側になっている。切欠き２１４は、弾性体２１において、筐体１０の内部側に形成されている。切欠き２１４によって、弾性体２１はより伸びやすくなり、嵩高な内装部品３５を筐体１０内により挿入しやすくなる。   Preferably, as shown in FIGS. 6 and 7, a cutout 214 is formed in the elastic body 21. The notch 214 is located between the opposite end surfaces 11a and 12a of the upper and lower housing members. The notch 214 extends along both end faces 11a and 12a. The elastic body 21 forms a concave shape by the notch 214, and in particular, has a U-shaped or U-shaped cross section as shown in FIG. The back part of this cross section is the outer surface side of the housing 10. The notch 214 is formed inside the housing 10 in the elastic body 21. The cutout 214 makes the elastic body 21 easier to extend, and makes it easier to insert the bulky interior part 35 into the housing 10.

なお、切欠き２１４は、筐体１０の長手方向に延在する弾性体２１に形成すれば十分であり、図３および図４に示した、第１およびし第２の防水蓋４１，４２用のパッキン部２１２，２１３には、形成しなくてもよい。   It is sufficient that the notch 214 is formed in the elastic body 21 extending in the longitudinal direction of the housing 10, and is used for the first and second waterproof lids 41 and 42 shown in FIGS. The packing portions 212 and 213 need not be formed.

（実施形態３）
本実施形態３では、弾性体に非接着部を形成し、弾性体の変形能を高める構造について説明する。なお、本実施形態３と前記実施形態１の共通点に関しては、前記実施形態１の記載を適宜参照することができるものとし、以下、主として、実施形態３と実施形態１の相違点について説明する。 (Embodiment 3)
In the third embodiment, a structure in which a non-adhesive portion is formed on an elastic body to enhance the deformability of the elastic body will be described. In addition, regarding the common points of the third embodiment and the first embodiment, the description of the first embodiment can be referred to as appropriate. Hereinafter, differences between the third embodiment and the first embodiment will be mainly described. .

図８は、実施形態３に係る筐体の横断面図である。図８を参照すると、弾性体２２はフランジ状に形成され、弾性体２２の凸部２２ａが両端面１１ａ，１２ａ間に挿入され、弾性体の基部２２ｂが上部および下部筐体部材１１，１２の内面と対向している。両端面１１ａ，１２ａ間には、凸部２２ａの頂面（外面）と当接するよう封止部材６１が装填されている。   FIG. 8 is a cross-sectional view of the housing according to the third embodiment. Referring to FIG. 8, the elastic body 22 is formed in a flange shape, the convex portion 22 a of the elastic body 22 is inserted between both end faces 11 a and 12 a, and the base 22 b of the elastic body is formed between the upper and lower housing members 11 and 12. Opposite the inner surface. A sealing member 61 is loaded between the both end faces 11a and 12a so as to come into contact with the top surface (outer surface) of the convex portion 22a.

さらに、弾性体２２と下部筐体部材１２の間には、部分的にマスキングシート５１が挟まれている。マスキングシート５１の長さは、筐体１０の長手方向長さよりも十分に短い。マスキングシート５１の材料には、テフロン（登録商標）素材などを用いることができる。マスクキングシート５１によって、弾性体２２には、部分的に筐体１０に接着しない部分、すなわち、非接着部２２ｃが形成される。これによって、弾性体２２はさらに伸びやすくなり、内装部材の実装時、筐体１０の開口部をより拡げることができる。これによって、嵩高な内装部品に合わせて、筐体１０の内容積を特別に大きく設計する必要がなくされ、筐体１０の体積が無駄に膨らむことを防止される。   Further, a masking sheet 51 is partially sandwiched between the elastic body 22 and the lower housing member 12. The length of the masking sheet 51 is sufficiently shorter than the length of the casing 10 in the longitudinal direction. As a material of the masking sheet 51, a Teflon (registered trademark) material or the like can be used. By the mask king sheet 51, the elastic body 22 is formed with a portion that is not partially bonded to the housing 10, that is, a non-bonded portion 22c. Thereby, the elastic body 22 becomes easier to extend, and the opening of the housing 10 can be further expanded when the interior member is mounted. Thereby, it is not necessary to design the inner volume of the housing 10 to be particularly large in accordance with the bulky interior parts, and the volume of the housing 10 is prevented from being unnecessarily expanded.

（実施形態４）
本実施形態４では、筐体の全体形状の他例について説明する。なお、本実施形態４と前記実施形態１の共通点に関しては、前記実施形態１の記載を適宜参照することができるものとし、以下、主として、実施形態４と実施形態１の相違点について説明する。 (Embodiment 4)
In the fourth embodiment, another example of the overall shape of the housing will be described. In addition, regarding the common points of the fourth embodiment and the first embodiment, the description of the first embodiment can be referred to as appropriate, and the differences between the fourth embodiment and the first embodiment will be mainly described below. .

前記実施形態では、図１を参照して、両端が開放および閉止自在な筐体について説明したが、本実施形態４では、有底袋状の筐体について説明する。   In the above embodiment, the case where both ends can be opened and closed has been described with reference to FIG. 1, but in the fourth embodiment, a bottomed bag-like case will be described.

図９は、実施形態４に係る筐体の分解図である。図９を参照すると、筐体１０は、一側が第１の防水蓋４１によって開放および閉止自在であり、他側が閉止されている。筐体１０の他側は、上部および下部筐体部材１１，１２並びに弾性体２１から構築される外壁によって、閉止されている。弾性体２１は、筐体１０の三辺（左右片および下辺）に亘って延在ないし連続的に形成されている。筐体１０の一側は、内装部品３２，３３，３４を筐体１０内に実装した後、第１の防水蓋４１によって閉止される。このように、本発明は、両端開放型の筐体だけではなく、一方開放型の袋状筐体にも適用される。   FIG. 9 is an exploded view of the housing according to the fourth embodiment. Referring to FIG. 9, the housing 10 is openable and closable on one side by a first waterproof lid 41, and the other side is closed. The other side of the casing 10 is closed by outer walls constructed from the upper and lower casing members 11 and 12 and the elastic body 21. The elastic body 21 extends or is continuously formed over the three sides (left and right pieces and the lower side) of the housing 10. One side of the housing 10 is closed by a first waterproof lid 41 after the interior parts 32, 33, 34 are mounted in the housing 10. As described above, the present invention is applied not only to an open-ended housing but also to an open-type bag-shaped housing.
