図３は、電極部材１５３、１５４が実装されたフレキシブル基板１６を示す平面図である。フレキシブル基板１６は、ポリイミド等の絶縁材料からなるフィルム状の部材に、接着層を介して導体箔からなる回路層を形成した基板である。フレキシブル基板１６は、電極部材１５３が実装される正極基板部１６１と、電極部材１５４が実装される負極基板部１６２と、これらの正極基板部１６１と負極基板部１６２とを連結する連結部１６３と、他の機能部が実装されるフレキシブル基板１６内の領域との連結部１６４、１６５とを含んでいる。実施の形態１において、電極部材１５３、１５４は、フレキシブル基板１６の同じ側の面に実装されている。 FIG. 3 is a plan view showing the flexible substrate 16 on which the electrode members 153 and 154 are mounted. The flexible substrate 16 is a substrate in which a circuit layer made of a conductive foil is formed on a film-like member made of an insulating material such as polyimide via an adhesive layer. The flexible substrate 16 includes a positive electrode substrate portion 161 on which the electrode member 153 is mounted, a negative electrode substrate portion 162 on which the electrode member 154 is mounted, and a connecting portion 163 that connects the positive electrode substrate portion 161 and the negative electrode substrate portion 162. , And connecting portions 164 and 165 with regions in the flexible substrate 16 on which other functional portions are mounted. In the first embodiment, the electrode members 153 and 154 are mounted on the same surface of the flexible substrate 16.

図３に示すように、電極部材１５３には、電池１５１と当接する側に打ち出された、高さが例えば０．２ｍｍ程度の複数（図３においては４つ）の凸部１５３ａが設けられている。これらの凸部１５３ａは、滑らかな正極面１５１ａとの接触面を小さくして、大きな接触圧を確保するために設けられている。凸部１５３ａの数や配置は、電池１５１との導通を確保することができれば限定されないが、好ましくは同一の２次元平面を通る３箇所以上（図３においては４箇所）に配置すると良い。なお、負極面１５２ｂは正極面１５１ａに比べると表面がざらついているため、負極面１５２ｂと当接する電極部材１５４には凸部を設ける必要はない。 As shown in FIG. 3, the electrode member 153 is provided with a plurality of (four in FIG. 3) convex portions 153 a having a height of, for example, about 0.2 mm, which is punched on the side in contact with the battery 151. Yes. These convex portions 153a are provided to reduce the contact surface with the smooth positive electrode surface 151a and ensure a large contact pressure. The number and arrangement of the protrusions 153a are not limited as long as the electrical connection with the battery 151 can be ensured, but the protrusions 153a are preferably arranged at three or more places (four places in FIG. 3) passing through the same two-dimensional plane. Since the negative electrode surface 152b has a rougher surface than the positive electrode surface 151a, the electrode member 154 in contact with the negative electrode surface 152b does not need to be provided with a convex portion.

図４は、組み付け部材１５５を示す斜視図である。組み付け部材１５５は、コの字状をなす板バネであり、互いに対向する正極側押圧部（第１の押圧部）１５５ａ及び負極側押圧部（第２の押圧部）１５５ｂと、これらの正極側押圧部１５５ａと負極側押圧部１５５ｂを連結する連結部１５５ｃとを有する。組み付け部材１５５の材料としては、薄肉板バネ用鋼材が用いられる。具体的には、ＳＵＳ３０４ＣＳＰ等のステンレス系の鋼材やＣ５２１０Ｐ等のリン青銅系の鋼材が挙げられる。 FIG. 4 is a perspective view showing the assembly member 155. The assembly member 155 is a U-shaped leaf spring, the positive side pressing part (first pressing part) 155a and the negative side pressing part (second pressing part) 155b facing each other, and these positive side It has the connection part 155c which connects the press part 155a and the negative electrode side press part 155b. As the material of the assembly member 155, a steel material for a thin plate spring is used. Specific examples include stainless steel materials such as SUS304CSP and phosphor bronze steel materials such as C5210P.

組み付け部材１５５は、フレキシブル基板１６の裏面（電極部材１５３、１５４の実装面と反対側の面）からフレキシブル基板１６を介して、電極部材１５３、２つの電池１５１、１５２、及び電極部材１５４（以下、電池等ともいう）をこの順で挟持する。そして、電極部材１５３を電池１５１の方向に向けて押圧すると共に、電極部材１５４を電池１５２の方向に向けて押圧する。図４に示すように、組み付け部材１５５に負荷がかかっていない状態（電池等を挟持していない状態）においては、正極側押圧部１５５ａと負極側押圧部１５５ｂとの間隔が先端に向かって狭くなっている。この先端を開いて電池等を挟み込むことにより、電極部材１５３、１５４に対する付勢力が発生する。この付勢力は、電池等のトータルの厚さが最大値又は最小値（電池が１つの場合）を取る場合であっても、所定範囲の荷重が電池等に加えられるようにするため、電池接点の接触抵抗が安定して低く抑えられるように設定されている。 The assembly member 155 includes an electrode member 153, two batteries 151, 152, and an electrode member 154 (hereinafter referred to as the electrode member 153 via the flexible substrate 16 from the back surface of the flexible substrate 16 (the surface opposite to the mounting surface of the electrode members 153, 154). Are also sandwiched in this order. Then, the electrode member 153 is pressed toward the battery 151 and the electrode member 154 is pressed toward the battery 152. As shown in FIG. 4, in a state where no load is applied to the assembly member 155 (a state where no battery or the like is sandwiched), the distance between the positive electrode side pressing portion 155a and the negative electrode side pressing portion 155b is narrower toward the tip. It has become. By opening the tip and sandwiching a battery or the like, a biasing force is generated against the electrode members 153 and 154. This urging force is applied to the battery contact point so that a predetermined range of load is applied to the battery even when the total thickness of the battery or the like takes the maximum value or the minimum value (when there is one battery). The contact resistance is set to be stable and low.

正極側押圧部１５５ａのうち、電極部材１５３と接触するバネの力点部分には、コの字の内側に向かって打ち出された、高さが例えば０．２ｍｍ程度の凸部１５５ｄが設けられている。図５は、正極側押圧部１５５ａの凸部１５５ｄと、電極部材１５３の凸部１５３ａとの位置関係を示す平面図である。正極側押圧部１５５ａの凸部１５５ｄは、電池部１５に組み付けられた際に、電極部材１５３に設けられた３つ以上（図５においては４つ）の凸部１５３ａによって囲まれる２次元領域（三角形以上の多角形の領域）の内側（好ましくは略中心部）に当接する位置に配置される。これにより、電極部材１５３の凸部１５３ａを均等に押圧し、電池１５１の正極面１５１ａとの導通を確実に確保することが可能となる。 Of the positive-side pressing portion 155a, a protruding portion 155d having a height of about 0.2 mm, for example, is provided at the force point portion of the spring that contacts the electrode member 153. . FIG. 5 is a plan view showing the positional relationship between the convex portion 155d of the positive electrode side pressing portion 155a and the convex portion 153a of the electrode member 153. The convex portion 155d of the positive electrode side pressing portion 155a is a two-dimensional region (see FIG. 5) that is surrounded by three or more (four in FIG. 5) convex portions 153a when assembled to the battery portion 15. It is arranged at a position where it abuts on the inner side (preferably the substantially central part) of a triangular region or more. Thereby, the convex part 153a of the electrode member 153 can be pressed evenly, and conduction with the positive electrode surface 151a of the battery 151 can be reliably ensured.

正極側押圧部１５５ａの先端部（凸部１５５ａよりも先の部分）は、組み付け部材１５５の外側に向かって「く」の字状に折り曲げられている。このように先端部を折り曲げることにより、組み付け部材１５５を電池等に組み付ける際の作業が容易になる。 The tip end portion of the positive electrode side pressing portion 155a (the portion ahead of the convex portion 155a) is bent toward the outside of the assembly member 155 in a “<” shape. By bending the tip portion in this manner, the work for assembling the assembly member 155 to a battery or the like is facilitated.

負極側押圧部１５５ｂの先端部は、組み付け部材１５５の外側に向かって開くように「く」の字状に折り曲げられている。この曲げ部分の稜線１５５ｅは、フレキシブル基板１６を介して電極部材１５４（図２参照）に当接可能な位置に設定されている。それにより、負極側押圧部１５５による付勢力が稜線１５５ｅの部分に集中し、フレキシブル基板１６を介して電極部材１５４を電池１５２に向けて押圧することが可能となる。 The tip of the negative electrode side pressing portion 155 b is bent in a “<” shape so as to open toward the outside of the assembly member 155. The ridge line 155e of the bent portion is set at a position where it can contact the electrode member 154 (see FIG. 2) through the flexible substrate 16. Accordingly, the urging force by the negative electrode side pressing portion 155 concentrates on the portion of the ridge line 155e, and the electrode member 154 can be pressed toward the battery 152 via the flexible substrate 16.

電池部１５の組み付けを行う際には、電極部材１５３、１５４が内側を向くようにフレキシブル基板１６の連結部１６３を湾曲させ、直列に並べた電池１５１、１５２を正極基板部１６１及び負極基板部１６２によって挟み込み、電池１５１の正極面１５１ａに電極部材１５３を当接させ、電池１５２の負極面１５２ｂに電極部材１５４を当接させる。そして、組み付け部材１５５の正極側押圧部１５５ａと負極側押圧部１５５ｂとの間を拡げてフレキシブル基板１６で挟んだ電池１５１、１５２を挿入し、組み付け部材１５５の復元力により押圧する。それによって、電池部１５が作製される。 When the battery part 15 is assembled, the connecting part 163 of the flexible substrate 16 is curved so that the electrode members 153 and 154 face inward, and the batteries 151 and 152 arranged in series are connected to the positive electrode part 161 and the negative electrode part. The electrode member 153 is brought into contact with the positive electrode surface 151 a of the battery 151, and the electrode member 154 is brought into contact with the negative electrode surface 152 b of the battery 152. Then, the batteries 151 and 152 sandwiched between the flexible substrate 16 are inserted by expanding the space between the positive electrode side pressing portion 155 a and the negative electrode side pressing portion 155 b of the assembly member 155, and pressed by the restoring force of the assembly member 155. Thereby, the battery part 15 is produced.

When the capsule medical device 1 is assembled, the illumination unit 11A, the imaging unit 12A, and the control unit 13 are assembled into a unit by assembling the spacer 17 in advance, and the illumination unit 11B, the imaging unit 12B, and the wireless communication unit 14 are assembled. Are assembled into a spacer 18 to form a unit. Further, the battery unit 15 is also prepared separately by the method described above. On the other hand, for the housing 10, a bottomed case is prepared by fitting the dome-shaped housing 103 into one open end of the cylindrical housing 101 and fixing it with an adhesive.

そして、円筒状筐体１０１及びドーム状筐体１０３からなる有底のケースに、スペーサ１８に組み付けられたユニットと、電池部１５と、スペーサ１７に組み付けられたユニットとを、この順に収納する。さらに、円筒状筐体１０１の他方の開口端にドーム状筐体１０２を嵌め込み、接着剤によって固定する。それにより、カプセル型医療装置１が完成する。 Then, the unit assembled to the spacer 18, the battery unit 15, and the unit assembled to the spacer 17 are stored in this order in a bottomed case including the cylindrical casing 101 and the dome-shaped casing 103. Further, the dome-shaped casing 102 is fitted into the other opening end of the cylindrical casing 101 and fixed with an adhesive. Thereby, the capsule medical device 1 is completed.

以上説明したように、本発明の実施の形態１によれば、電極部材１５３、１５４が実装されたフレキシブル基板１６によって電池１５１、１５２を挟み込み、バネ弾性を有するコの字状の組み付け部材１５５によってこれらの電池等を一体化させるので、リジッド基板を用いることなく、電池１５１、１５２と電極部材１５３、１５４との接点を確保した状態で、これらの電池１５１、１５２を保持することが可能となる。従って、カプセル内を省スペース化することが可能となる。 As described above, according to the first embodiment of the present invention, the batteries 151 and 152 are sandwiched by the flexible substrate 16 on which the electrode members 153 and 154 are mounted, and the U-shaped assembly member 155 having spring elasticity is used. Since these batteries and the like are integrated, it is possible to hold the batteries 151 and 152 in a state where the contact points between the batteries 151 and 152 and the electrode members 153 and 154 are secured without using a rigid substrate. . Therefore, the space inside the capsule can be saved.

The electrode member 157 has a mortar-shaped recess 157 a provided on the back surface of the contact surface with the battery 151. The recess 157a is formed by, for example, a punching process.

図７に示すように、電極部材１５７を用いる場合、組み付け部材１５５の正極側押圧部１５５ａに設けられた凸部１５５ｄがフレキシブル基板１６を介して凹部１５７ａに入り込み、正極側押圧部１５５ａによる付勢力を凹部１５７ａに集中させることができる。従って、電極部材１５７と電池１５１の正極面１５１ａとの接点を確実に確保することが可能となる。 As shown in FIG. 7, when using the electrode member 157, the convex part 155d provided in the positive electrode side pressing part 155a of the assembly member 155 enters the concave part 157a via the flexible substrate 16, and the urging force by the positive electrode side pressing part 155a. Can be concentrated in the recess 157a. Therefore, it is possible to reliably secure a contact point between the electrode member 157 and the positive electrode surface 151a of the battery 151.

腕部２２４は、先端部がＴ字形状をなし、電池ホルダ２１０の外周面に沿って湾曲している。この腕部２２４を上述した電池ホルダ２１０の溝部２１５に嵌合させることにより、電池ホルダ２１０と組み付け部材２２０との間において、周方向における回転及び軸方向における移動が規制される。 The arm portion 224 has a T-shaped tip and is curved along the outer peripheral surface of the battery holder 210. By fitting the arm portion 224 into the groove portion 215 of the battery holder 210 described above, rotation in the circumferential direction and movement in the axial direction are restricted between the battery holder 210 and the assembly member 220.

次に、電池部２０の組み付け方法を説明する。まず、フレキシブル基板１６の負極基板部１６２を電池ホルダ２１０に嵌め込む。この際、負極基板部１６２に実装された電極部材１５４を内側に向け、負極基板部１６２の裏面をストッパ部２１２、２１３に当接させる。さらに、フレキシブル基板１６の連結部１６４、１６５を切り欠き２１４に嵌め込む。 Next, a method for assembling the battery unit 20 will be described. First, the negative electrode substrate portion 162 of the flexible substrate 16 is fitted into the battery holder 210. At this time, the electrode member 154 mounted on the negative electrode substrate portion 162 is directed inward, and the back surface of the negative electrode substrate portion 162 is brought into contact with the stopper portions 212 and 213. Further, the connecting portions 164 and 165 of the flexible substrate 16 are fitted into the notches 214.

続いて、電池１５２、１５１を、負極面１５２ｂ、１５１ｂを電極部材１５４側に向けて、電池ホルダ２１０に順次嵌め込む。そして、フレキシブル基板１６の連結部１６３を湾曲させ、正極基板部１６１に実装された電極部材１５３を正極面１５１ａに当接させる。 Subsequently, the batteries 152 and 151 are sequentially fitted into the battery holder 210 with the negative electrode surfaces 152b and 151b facing the electrode member 154 side. And the connection part 163 of the flexible substrate 16 is curved, and the electrode member 153 mounted on the positive electrode substrate part 161 is brought into contact with the positive electrode surface 151a.

続いて、組み付け部材２２０の腕部２２４の向きを電池ホルダ２１０の溝部２１５に合わせ、フレキシブル基板１６及びこれに挟まれた電池１５１、１５２及び電極部材１５３、１５４に組み付け部材２２０を嵌め込み、溝部２１５に腕部２２４を嵌合させる。それにより、正極側押圧部２２１及び負極側押圧部２２２によって正極基板部１６１及び負極基板部１６２を介して電極部材１５３、１５４がそれぞれ押圧され、電池１５１、１５２が固定される。 Subsequently, the direction of the arm portion 224 of the assembly member 220 is aligned with the groove portion 215 of the battery holder 210, and the assembly member 220 is fitted into the flexible substrate 16, the batteries 151 and 152 and the electrode members 153 and 154 sandwiched therebetween, and the groove portion 215.

In addition, since the battery holder 210 and the assembly member 220 are aligned via the arm portion 224 and the groove portion 215, the rotation of the batteries 151 and 152 in the circumferential direction and the movement in the axial direction can be restricted, and the battery 151 can be regulated. , 152 in the radial direction can be determined. Thereby, since the power point of the positive electrode side pressing part 221 and the negative electrode side pressing part 222 and the action point of the electrode members 153 and 154 can be maintained on the central axes of the batteries 151 and 152, the battery 151, It is possible to ensure the contact points of the electrode members 153 and 154 with respect to 152.

次に、本発明の実施の形態３について説明する。図１３及び図１４は、本発明の実施の形態３に係る電池の組み付け構造を示す一部断面図である。このうち、図１３は、組み付けられる電池が１つである場合を示し、図１４は、組み付けられる電池が２つである場合を示す。 (Embodiment 3)
Next, a third embodiment of the present invention will be described. 13 and 14 are partial cross-sectional views showing the battery assembly structure according to Embodiment 3 of the present invention. Among these, FIG. 13 shows a case where one battery is assembled, and FIG. 14 shows a case where two batteries are assembled.

図１３に示すように、実施の形態３に係る電池の組み付け構造としての電池部３０は、ボタン型の電池１５１と、電極部材３０２、３０３が実装されたフレキシブル基板３０１と、組み付け部材３０４とを備える。なお、電池１５１の構造は実施の形態１と同様である。 As shown in FIG. 13, the battery unit 30 as the battery assembly structure according to Embodiment 3 includes a button-type battery 151, a flexible substrate 301 on which electrode members 302 and 303 are mounted, and an assembly member 304. Prepare. Note that the structure of the battery 151 is the same as that of Embodiment 1.

フレキシブル基板３０１は、ポリイミド等の絶縁材料からなるフィルム状の部材に、接着層を介して導体箔からなる回路層を形成した基板であり、図１に示すフレキシブル基板１６と同様に、照明部１１Ａ〜無線通信部１４と電池部３０とが実装される基板である。フレキシブル基板３０１においては、電池部３０との電気的な接点となる電極部材３０２、３０３が、フレキシブル基板３０１の反対側の面にそれぞれ設けられている。具体的には、電極部材３０２は、組み付け部材３０４に面した側（図１３においては左側）に実装され、電極部材３０３は、その裏面（図１３においては右側、電池１５１の負極面１５１ｂと当接する側の面）に実装されている。 The flexible substrate 301 is a substrate in which a circuit layer made of a conductive foil is formed on a film-like member made of an insulating material such as polyimide via an adhesive layer. Like the flexible substrate 16 shown in FIG. A substrate on which the wireless communication unit 14 and the battery unit 30 are mounted. In the flexible substrate 301, electrode members 302 and 303 that are electrical contacts with the battery unit 30 are provided on the opposite surface of the flexible substrate 301. Specifically, the electrode member 302 is mounted on the side facing the assembly member 304 (left side in FIG. 13), and the electrode member 303 is in contact with the back surface (right side in FIG. 13 and the negative electrode surface 151b of the battery 151). It is mounted on the surface that comes into contact.

組み付け部材３０４は、コの字状をなす板バネであり、互いに対向する第１押圧部３０５及び第２押圧部３０６と、これらの第１押圧部３０５と第２押圧部３０６とを連結する連結部３０７とを有する。組み付け部材３０４の材料としては、ＳＵＳ３０４ＣＳＰ等のステンレス系の鋼材やＣ５２１０Ｐ等のリン青銅系の鋼材に代表される薄肉板バネ用鋼材が用いられる。 The assembly member 304 is a U-shaped leaf spring, and the first pressing portion 305 and the second pressing portion 306 that face each other, and a connection that connects the first pressing portion 305 and the second pressing portion 306 to each other. Part 307. As the material of the assembly member 304, a thin plate spring steel material typified by a stainless steel material such as SUS304CSP or a phosphor bronze steel material such as C5210P is used.

第１押圧部３０５の先端部は、組み付け部材３０４の外側に向かって開くように「く」の字状に折り曲げられている。この曲げ部分の稜線３０８は、正極面１５１ａの中央付近に当接可能な位置に設定されている。それにより、第１押圧部３０５による付勢力が稜線３０８の部分に集中し、第１押圧部３０５を正極面１５１ａに接触させて確実に押圧することが可能となる。なお、第１押圧部３０５に、正極面１５１ａとの接点として、組み付け部材３０４の内側に向かって突出する凸部をさらに設けても良い。 The front end portion of the first pressing portion 305 is bent in a “<” shape so as to open toward the outside of the assembly member 304. The ridge line 308 of the bent portion is set at a position where it can come into contact with the vicinity of the center of the positive electrode surface 151a. Thereby, the urging force by the first pressing portion 305 concentrates on the portion of the ridge line 308, and the first pressing portion 305 can be brought into contact with the positive electrode surface 151a and reliably pressed. In addition, you may further provide the convex part which protrudes toward the inner side of the assembly | attachment member 304 in the 1st press part 305 as a contact with the positive electrode surface 151a.

また、第２押圧部３０６の先端部も、組み付け部材３０４の外側に向かって「く」の字状に折り曲げられている。このように先端部を折り曲げることにより、組み付け部材３０４を電池等に組み付ける際の作業が容易になる。 In addition, the distal end portion of the second pressing portion 306 is also bent in a “<” shape toward the outside of the assembly member 304. By bending the tip portion in this manner, the work for assembling the assembly member 304 to a battery or the like is facilitated.

電池部３０の組み付けを行う際には、電極部材３０３を電池１５１の負極面１５１ｂに当接させると共に、第１押圧部３０５を電池１５１の正極面１５１ａ側に合わせ、電極部材３０２、フレキシブル基板３０１、電極部材３０３、及び電池１５１をこの並び順で組み付け部材３０４によって挟持する。この際、フレキシブル基板３０１の端部３０９を延伸させて電池１５１の外周面と組み付け部材３０４との間に配置し、電池１５１のショートを防止することが好ましい。それにより、電池１５１の正極面１５１ａが、第１押圧部３０５を含む組み付け部材３０４を介して電極部材３０２と導通される。 When assembling the battery unit 30, the electrode member 303 is brought into contact with the negative electrode surface 151 b of the battery 151, and the first pressing unit 305 is aligned with the positive electrode surface 151 a side of the battery 151. The electrode member 303 and the battery 151 are sandwiched by the assembly member 304 in this arrangement order. At this time, it is preferable to prevent the short circuit of the battery 151 by extending the end 309 of the flexible substrate 301 and disposing it between the outer peripheral surface of the battery 151 and the assembly member 304. Thereby, the positive electrode surface 151 a of the battery 151 is electrically connected to the electrode member 302 through the assembly member 304 including the first pressing portion 305.

図１４に示す組み付け構造の電池部３１においては、電極部材３０２、３０３が実装されたフレキシブル基板３０１及び電池１５１、１５２を電池ホルダ２１０（図８参照）によって保持した状態で、組み付け部材３０４を組み付けている。電池ホルダ２１０を用いることにより、電池１５１、１５２の回転や位置ずれを規制することができると共に、正極面１５１ａと組み付け部材３０４との接点を確実に確保することが可能となる。 In the battery unit 31 having the assembly structure shown in FIG. 14, the assembly member 304 is assembled in a state where the flexible substrate 301 on which the electrode members 302 and 303 are mounted and the batteries 151 and 152 are held by the battery holder 210 (see FIG. 8). ing. By using the battery holder 210, the rotation and displacement of the batteries 151 and 152 can be restricted, and the contact point between the positive electrode surface 151a and the assembly member 304 can be reliably secured.

このような実施の形態３によれば、組み付け部材３０４の第１押圧部３０５を正極面１５１ａとの電極と兼用することにより、凸部１５３ａが設けられた電極部材１５３（図２参照）のように厚みのある部材を用いる必要がなくなるので、電池部３０のさらなる省スペース化が可能となる。また、フレキシブル基板３０１の扱いが容易になるので、電池部３０の組み付け工程を簡素化することも可能となる。 According to the third embodiment, the first pressing portion 305 of the assembly member 304 is also used as an electrode with the positive electrode surface 151a, so that the electrode member 153 provided with the convex portion 153a (see FIG. 2). Therefore, it is not necessary to use a thick member, so that further space saving of the battery unit 30 is possible. Moreover, since the handling of the flexible substrate 301 becomes easy, the assembly process of the battery unit 30 can be simplified.

（実施の形態４）
次に、本発明の実施の形態４について説明する。図１５は、本発明の実施の形態４に係る電池の組み付け構造を示す一部断面図である。図１５に示すように、実施の形態４においては、電池部１５と、スペーサ１７に機能部（照明部１１Ａ、撮像部１２Ａ、及び制御部１３）が組み付けられたユニットと、スペーサ１８に機能部（照明部１１Ｂ、撮像部１２Ｂ、及び無線通信部１４）が組み付けられたユニットとを筐体１０内に収納する際に、電池部１５とスペーサ１８との間に付勢部材４００を配置することにより、各ユニット間に、筐体１０の長軸Ｌａ方向における付勢力を付与している。 (Embodiment 4)
Next, a fourth embodiment of the present invention will be described. FIG. 15 is a partial cross-sectional view showing a battery assembly structure according to Embodiment 4 of the present invention. As shown in FIG. 15, in the fourth embodiment, a battery unit 15, a unit in which a functional unit (illumination unit 11 </ b> A, imaging unit 12 </ b> A, and control unit 13) is assembled to the spacer 17, and a functional unit to the spacer 18. The energizing member 400 is arranged between the battery unit 15 and the spacer 18 when housing the unit in which the (illuminating unit 11B, the imaging unit 12B, and the wireless communication unit 14) are assembled in the housing 10. Thus, an urging force in the long axis La direction of the housing 10 is applied between the units.

付勢部材４００は、ＳＵＳ３０４ＣＳＰ等のステンレス系の鋼材やＣ５２１０Ｐ等のリン青銅系の鋼材に代表される薄肉板バネ用鋼材によって形成された板状部材の一部を屈曲させたものである。付勢部材４００は、スペーサ１８と平行に配置されたベース部４０１と、ベース部４０１に対して立ち上げられたバネ部４０２とを有する。バネ部４０２の先端には、電池部１５側に打ち出された接点部４０３が設けられている。 The urging member 400 is obtained by bending a part of a plate-like member formed of a stainless steel material such as SUS304CSP or a thin steel plate spring represented by a phosphor bronze steel material such as C5210P. The biasing member 400 includes a base portion 401 disposed in parallel with the spacer 18 and a spring portion 402 raised with respect to the base portion 401. At the tip of the spring portion 402, a contact portion 403 that is driven out toward the battery portion 15 is provided.

カプセル型医療装置を組み立てる際には、図１に示すように、円筒状筐体１０１にドーム状筐体１０３を嵌め込み、接着剤によって固定した有底のケースに、スペーサ１８に機能部が組み付けられたユニットを収納し、付勢部材４００を配置する。なお、付勢部材４００は、スペーサ１８に予め組み付けておいても良い。 When the capsule medical device is assembled, as shown in FIG. 1, the functional part is assembled to the spacer 18 in the bottomed case in which the dome-shaped housing 103 is fitted into the cylindrical housing 101 and fixed with an adhesive. The urging member 400 is disposed. The urging member 400 may be assembled to the spacer 18 in advance.

続いて、有底ケースに電池部１５を挿入し、さらに、スペーサ１７に機能部が組み付けられたユニットを挿入する。そして、このユニットを押し込んでバネ部４０２を潰れさせた状態で、円筒状筐体１０１にドーム状筐体１０２を嵌め込み、接着剤によって固定する。それにより、接点部４０３が組み付け部材１５５に接触し、バネ部４０２の復元力により、ユニット間に筐体１０の長軸Ｌａ方向（図１参照）の付勢力が発生する。なお、付勢部材４００によるバネ力は、カプセル型医療装置に対して振動等の外力が加わった場合であっても、筐体１０内に収納された各部品の移動が生じないように予め設定されている。 Subsequently, the battery unit 15 is inserted into the bottomed case, and further, a unit in which the functional unit is assembled to the spacer 17 is inserted. Then, in a state where the unit is pushed in and the spring portion 402 is crushed, the dome-shaped casing 102 is fitted into the cylindrical casing 101 and fixed with an adhesive. As a result, the contact portion 403 comes into contact with the assembly member 155, and the urging force in the long axis La direction (see FIG. 1) of the housing 10 is generated between the units by the restoring force of the spring portion 402. Note that the spring force by the biasing member 400 is set in advance so that movement of each component housed in the housing 10 does not occur even when an external force such as vibration is applied to the capsule medical device. Has been.

このような付勢部材４００を用いることにより、スペーサ１７、１８は、筐体１０の長軸Ｌａ方向において移動可能な最端部に常に配置されることになる。それにより、スペーサ１７、１８にそれぞれ組み付けられた撮像部１２Ａ、１２Ｂも、この最端部を基準とする規定位置に常に配置される。従って、筐体１０内に収納される各部品の形状に多少のばらつきがあったとしても、ドーム状筐体１０２、１０３のドーム部分の球心に対し、撮像部１２Ａ、１２Ｂのレンズユニット１２１（図１参照）のひとみ中心位置を確実に位置決めすることが可能となる。 By using such an urging member 400, the spacers 17 and 18 are always arranged at the endmost portion that can move in the major axis La direction of the housing 10. As a result, the imaging units 12A and 12B assembled to the spacers 17 and 18 are also always arranged at specified positions with the extreme end as a reference. Therefore, even if there is some variation in the shape of each component housed in the housing 10, the lens units 121 (in the imaging units 12A and 12B with respect to the spheres of the dome portions of the dome-shaped housings 102 and 103). The pupil center position (see FIG. 1) can be reliably positioned.

なお、筐体１０内における付勢部材４００の配置は、電池部１５における組み付け部材１５５から電池１５１、１５２への力の伝達経路の外側であれば、特に限定されない。例えば、電池部１５とスペーサ１７との間に付勢部材４００を配置しても良い。 The arrangement of the urging member 400 in the housing 10 is not particularly limited as long as it is outside the force transmission path from the assembly member 155 to the batteries 151 and 152 in the battery unit 15. For example, the urging member 400 may be disposed between the battery unit 15 and the spacer 17.

（実施の形態５）
次に、本発明の実施の形態５について説明する。図１に示すように、円筒状筐体１０１及びドーム状筐体１０２、１０３という複数の部品によって筐体１０を構成する場合、筐体１０内に閉じ込められた空気がこれらの部品間の嵌合部に侵入してエアパスが発生し、カプセル型医療装置の歩留まりが低下する場合があった。 (Embodiment 5)
Next, a fifth embodiment of the present invention will be described. As shown in FIG. 1, when the casing 10 is constituted by a plurality of parts such as the cylindrical casing 101 and the dome-shaped casings 102 and 103, the air trapped in the casing 10 is fitted between these parts. There is a case where the yield of the capsule medical device is lowered due to an air path generated by entering the part.

そこで、実施の形態５においては、筐体１０を構成する部品間の嵌合部における水密が確実に確保されるように、以下のように各部品の形状及びサイズを規定する。なお、円筒状筐体１０１とドーム状筐体１０２、１０３との嵌合部の構造は同一であるため、以下においては、円筒状筐体１０１とドーム状筐体１０２との嵌合部の構造を代表して説明する。 Therefore, in the fifth embodiment, the shape and size of each component are defined as follows so as to ensure watertightness in the fitting portion between the components constituting the housing 10. In addition, since the structure of the fitting part of the cylindrical housing | casing 101 and the dome-shaped housings 102 and 103 is the same, in the following, the structure of the fitting part of the cylindrical housing 101 and the dome-shaped housing 102 is shown. This will be described as a representative.

図１に示すように、円筒状筐体１０１とドーム状筐体１０２との嵌合部は、大まかには、円筒状筐体１０１の端部の内周面を切り欠くことにより内径を拡げると共に、ドーム状筐体１０２の端部の外周面を切り欠くことにより外径を小さくし、円筒状筐体１０１の端部をドーム状筐体１０２の端部に被せ、円筒状筐体１０１の端面がドーム状筐体１０２の切り欠き部の端面に当接するまで嵌合させる構造となっている。 As shown in FIG. 1, the fitting portion between the cylindrical casing 101 and the dome-shaped casing 102 broadens the inner diameter by roughly cutting the inner peripheral surface of the end of the cylindrical casing 101. The outer diameter of the end of the dome-shaped casing 102 is cut away to reduce the outer diameter, the end of the cylindrical casing 101 is covered with the end of the dome-shaped casing 102, and the end surface of the cylindrical casing 101 is Is configured to be fitted until it comes into contact with the end face of the cutout portion of the dome-shaped casing 102.

より詳細には、ドーム状筐体１０２側の嵌合部においては、嵌合面（切り欠かれた部分の外周面）の一部に凹部（溝部）を一周に渡って形成すると共に、嵌合部のうち、凹部よりもドームの頂点側の領域（以下、第１ドーム嵌合領域という）に対し、凹部よりも端部側の領域（以下、第２ドーム嵌合領域という）の外形を小さくする（即ち、肉薄にする）。一方、円筒状筐体１０１側の嵌合部においては、嵌合面の内径を均一にして円柱側面状にすると共に、この円柱側面状の内周面（以下、端部内周面という）に、ドーム状筐体１０２の嵌合部に設けた凹部に嵌合可能な凸部を一周に渡って形成する。この凸部の位置は、円筒状筐体１０１の端面をドーム状筐体１０２の切り欠き部の端面に当接させたときに、ドーム状筐体１０２側の凹部に嵌合する位置に設定する。さらに、上記端部内周面の先端部のみをテーパー面とすることにより、円筒状筐体１０１とドーム状筐体１０２とを嵌合させ易くする。 More specifically, in the fitting portion on the dome-shaped housing 102 side, a concave portion (groove portion) is formed over a part of the fitting surface (outer peripheral surface of the notched portion) and fitted. The outer shape of the region closer to the end than the recess (hereinafter referred to as the second dome fitting region) is smaller than the region of the portion closer to the top of the dome than the recess (hereinafter referred to as the first dome fitting region). (Ie, make it thin). On the other hand, in the fitting part on the cylindrical housing 101 side, the inner diameter of the fitting surface is made uniform to make a cylindrical side surface, and the inner peripheral surface of this cylindrical side surface (hereinafter referred to as an end inner peripheral surface) A convex portion that can be fitted into a concave portion provided in the fitting portion of the dome-shaped casing 102 is formed over one circumference. The position of the convex portion is set to a position where it fits into the concave portion on the dome-shaped housing 102 side when the end surface of the cylindrical housing 101 is brought into contact with the end surface of the cutout portion of the dome-shaped housing 102. . Furthermore, by making only the tip of the inner peripheral surface of the end portion a tapered surface, the cylindrical casing 101 and the dome-shaped casing 102 can be easily fitted.

円筒状筐体１０１とドーム状筐体１０２との嵌合部の形状及びサイズの関係を上記のように規定することにより、両者を嵌合させた際、第１ドーム嵌合領域（外径が大きい方の領域）と円筒状筐体１０１の端部内周面とが対向する領域における隙間の幅よりも、第２ドーム嵌合領域（外径が小さい方の領域）と円筒状筐体１０１の端部内周面とが対向する領域における隙間の幅の方が広くなる。 By defining the relationship between the shape and size of the fitting portion between the cylindrical housing 101 and the dome-shaped housing 102 as described above, when the two are fitted, the first dome fitting region (outer diameter is The second dome fitting region (region having a smaller outer diameter) and the cylindrical housing 101 are larger than the width of the gap in the region where the larger region) and the inner peripheral surface of the end of the cylindrical housing 101 face each other. The width of the gap in the region facing the end inner peripheral surface is wider.

円筒状筐体１０１とドーム状筐体１０２とを嵌合させる際には、両者の嵌合面に接着剤を塗布し、ドーム状筐体１０２側の嵌合部に円筒状筐体１０１側の嵌合部を被せ、ドーム状筐体１０２側に形成された凹部に円筒状筐体１０１側に形成された凸部を嵌め込む。これにより、嵌合面に塗布された接着剤が、まず、ドーム状筐体１０２の第１ドーム嵌合領域と円筒状筐体１０１の端部内周面との隙間（幅の狭い方の隙間）に行き渡ってこの隙間を塞ぎ、余った接着剤が、上記凹部と凸部とが嵌合した領域（以下、凹凸嵌合領域という）を通って、ドーム状筐体１０２の第２ドーム嵌合領域と円筒状筐体１０１の端部内周面との隙間（幅の広い方の隙間）に流れ込む。即ち、円筒状筐体１０１とドーム状筐体１０２とは、幅の狭い方の隙間及び幅の広い方の隙間の２周に渡って封止される。それにより、筐体１０内部の空気がドーム状筐体１０２の第２ドーム嵌合領域と円筒状筐体１０１の端部内周面との隙間（幅の広い方の隙間）に侵入したとしても、この空気は、上記凹凸嵌合領域に留まり、第１ドーム嵌合領域と円筒状筐体１０１の端部内周面との隙間（幅の狭い方の隙間）にはほとんど侵入しない。その結果、円筒状筐体１０１とドーム状筐体１０２との嵌合部にエアパスが発生し難くなり、カプセル型医療装置の歩留まりを向上させることが可能となる。 When the cylindrical casing 101 and the dome-shaped casing 102 are fitted to each other, an adhesive is applied to the fitting surfaces of the two, and the fitting portion on the dome-shaped casing 102 side is attached to the fitting section on the cylindrical casing 101 side. The fitting portion is covered, and the convex portion formed on the cylindrical housing 101 side is fitted into the concave portion formed on the dome-shaped housing 102 side. As a result, the adhesive applied to the fitting surface first has a gap between the first dome fitting region of the dome-shaped casing 102 and the inner peripheral surface of the end of the cylindrical casing 101 (a narrower gap). The second dome fitting region of the dome-shaped casing 102 through the region where the concave portion and the convex portion are fitted (hereinafter referred to as the concave and convex fitting region). And the gap between the inner peripheral surface of the end of the cylindrical casing 101 (the wider gap). That is, the cylindrical casing 101 and the dome-shaped casing 102 are sealed over two circumferences of the narrower gap and the wider gap. Thereby, even if the air inside the housing 10 enters the gap (the wider gap) between the second dome fitting region of the dome-shaped housing 102 and the inner peripheral surface of the end of the cylindrical housing 101, This air stays in the concave-convex fitting region and hardly enters the gap (narrower gap) between the first dome fitting region and the inner peripheral surface of the end of the cylindrical housing 101. As a result, it is difficult for an air path to occur in the fitting portion between the cylindrical casing 101 and the dome-shaped casing 102, and the yield of the capsule medical device can be improved.

以上説明した実施の形態１〜５及びこれらの変形例は、本発明を実施するための例にすぎず、本発明はこれらに限定されるものではない。また、本発明は、実施の形態１〜５及び各変形例に開示されている複数の構成要素を適宜組み合わせることによって、種々の発明を形成できる。本発明は、仕様等に応じて種々変形することが可能であり、更に本発明の範囲内において、他の様々な実施の形態が可能であることは、上記記載から自明である。 Embodiments 1 to 5 described above and modifications thereof are merely examples for carrying out the present invention, and the present invention is not limited to these.
