Description
本発明は電子機器の筐体構造に関し、特には電池駆動型の電子機器の小型化に有用な筐体構造に関する。 The present invention relates to a housing structure of an electronic device, and more particularly to a housing structure useful for downsizing a battery-driven electronic device.
電子機器、特に携帯型の電子機器については小型化が重要な課題である。携帯型の電子機器は電池駆動型であることが多いが、回路の小型化に比べて電池の小型化は進んでおらず、電池の収容スペースを確保しながら電子機器を小型化することは容易でない。特に、乾電池のように大きさが規格化されている電池を用いる必要のある電子機器では、専用の充電池を用いる電子機器よりも小型化が困難である。 Miniaturization is an important issue for electronic devices, especially portable electronic devices. Portable electronic devices are often battery-powered, but the size of the battery has not been reduced compared to the size of the circuit, and it is easy to reduce the size of the electronic device while securing the battery storage space. Not. In particular, in an electronic device that needs to use a standardized battery such as a dry battery, it is more difficult to reduce the size than an electronic device that uses a dedicated rechargeable battery.
乾電池（１次電池および２次電池を含む）で駆動される小型電子機器では、乾電池の両端にある電極から回路に通電するための電極板の他、確実に通電するために電池を長さ方向に押圧するバネ等が必要である。そして、このバネ等の押圧力に対向して電極板を支持する必要があるため、電極板の支持部材を樹脂で形成する場合には、強度を持たせるために厚く形成せざるを得ず、電子機器の小型化を妨げる要因となっていた（非特許文献１）。 In a small electronic device driven by a dry battery (including a primary battery and a secondary battery), in addition to an electrode plate for energizing the circuit from the electrodes at both ends of the dry battery, the battery is lengthwise to ensure energization. A spring or the like that presses against is required. And, since it is necessary to support the electrode plate facing the pressing force of this spring or the like, when forming the electrode plate support member with resin, it must be formed thick in order to give strength, This has been a factor that hinders downsizing of electronic devices (Non-Patent Document 1).
図５は、乾電池を電源とする従来の小型電子機器の一例としてのホルタ心電計の筐体構造を示す図である。（ａ），（ｂ）は電池カバーを取り除いた状態の側面図および断面図であり、（ｃ）は電池からの電源供給に係る構成を説明するための図である。 FIG. 5 is a diagram showing a housing structure of a Holter electrocardiograph as an example of a conventional small electronic device using a dry battery as a power source. (A), (b) is the side view and sectional drawing of the state which removed the battery cover, (c) is a figure for demonstrating the structure which concerns on the power supply from a battery.
ホルタ心電計２００は電源である電池１７０を収容する電池収容部１８０を有している。電池収容部１８０は筐体の一部を構成する着脱可能な電池カバー１６０で覆われており、電池カバー１６０を取り外すことで電池１７０を着脱することができる。 The Holter electrocardiograph 200 has a battery housing portion 180 that houses a battery 170 as a power source. The battery housing part 180 is covered with a detachable battery cover 160 that constitutes a part of the housing, and the battery 170 can be attached and detached by removing the battery cover 160.
電池収容部１８０には、電池１７０の高さ方向の両端面（もしくは平行な２つの電極面）に存在する正極および負極から電気を取り出すための電極板１７１，１７３が設けられている。また、負極側の電極板１７３には、電池１７０の電極と電極板１７１，１７３との接触を安定させるとともに、電池１７０を支持するためのコイルバネ１７２が接続されている。そして、電極板１７１はコード１７８に、電極板１７３はコード１７６に接続され、コネクタ１７７を通じて回路基板に接続される。 The battery housing portion 180 is provided with electrode plates 171 and 173 for taking out electricity from the positive electrode and the negative electrode present on both end surfaces (or two parallel electrode surfaces) in the height direction of the battery 170. The electrode plate 173 on the negative electrode side is connected to a coil spring 172 for stabilizing the contact between the electrode of the battery 170 and the electrode plates 171 and 173 and supporting the battery 170. The electrode plate 171 is connected to the cord 178, the electrode plate 173 is connected to the cord 176, and is connected to the circuit board through the connector 177.
電極板１７１，１７３自体は薄い金属板であるため、他の部材で支持しないと、コイルバネ１７２の反発力や電池装着時に加わる力により電極板１７１，１７３が折れ曲がってしまう。一方、電池カバー１６０は着脱式であり、電池１７０の取り付けおよび取り外し時には外されるため、電池カバー１６０で電極板１７１，１７３を支持することはできない。そのため、電極板１７１，１７３を支持する支持部材１７４，１７５が設けられる。 Since the electrode plates 171 and 173 themselves are thin metal plates, the electrode plates 171 and 173 are bent due to the repulsive force of the coil spring 172 and the force applied when the battery is mounted unless supported by other members. On the other hand, since the battery cover 160 is detachable and is removed when the battery 170 is attached and detached, the electrode plates 171 and 173 cannot be supported by the battery cover 160. Therefore, support members 174 and 175 for supporting the electrode plates 171 and 173 are provided.
電池１７０を保持しつつ安定して電気を取り出すには反発力の強いコイルバネ１７２を用いる必要があり、電極板１７１，１７３には強い力が加わる。従って、電極板１７１，１７３を支持するための支持部材１７４，１７５には剛性と強度が要求される。一般に支持部材１７４，１７５を含めた筐体は樹脂で形成されるため、支持部材１７４，１７５を厚く形成する必要がある。また、支持部材１７４，１７５の外側に筐体本体を形成するため、電池１７０の高さ方向（図５の左右方向）における筐体の大きさを削減することが困難だった。 In order to stably take out electricity while holding the battery 170, it is necessary to use a coil spring 172 having a strong repulsive force, and a strong force is applied to the electrode plates 171 and 173. Accordingly, the support members 174 and 175 for supporting the electrode plates 171 and 173 are required to have rigidity and strength. In general, since the housing including the support members 174 and 175 is formed of resin, the support members 174 and 175 need to be formed thick. In addition, since the casing body is formed outside the support members 174 and 175, it is difficult to reduce the size of the casing in the height direction of the battery 170 (the left-right direction in FIG. 5).
本発明はこのような従来技術の課題に鑑みなされたものであって、電池を電源として用いる電子機器において、小型化に有利な筐体構造を提供することを目的とする。 The present invention has been made in view of such a problem of the prior art, and an object of the present invention is to provide a housing structure that is advantageous for downsizing in an electronic device using a battery as a power source.

The housing body has a battery housing portion that houses the battery, and the battery housing portion is provided in the housing body and opened by the user. And an opening / closing part that enables replacement of the battery accommodated in the container, and the opening / closing part is provided with a packing for preventing liquid and / or dust from entering the casing body from the outside. , packing is formed by coating a flat conductor with a resin, in a state where the opening and closing unit is closed, the first portion in contact with the at least one electrode of the batteries of the opening portion, the opening and closing portion of an electronic device By providing no resin coating on the portion of the packing that forms the second portion that contacts the terminal connected to the power supply line of the circuit board , the plate-like conductor is connected to the first portion and the second portion.

このような構成により、本発明によれば、電池を電源として用いる電子機器において、小型化に有利な筐体構造を提供することができる。 With such a configuration, according to the present invention, it is possible to provide a housing structure that is advantageous for downsizing in an electronic device using a battery as a power source.
以下、図面を参照して本発明の例示的な実施形態について詳細に説明する。なお、以下では、本発明に係る筐体構造をホルタ心電計に適用した実施形態について説明するが、本発明に係る筐体構造は、任意の電子機器に対して適用可能である。 Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings. In the following, an embodiment in which the housing structure according to the present invention is applied to a Holter electrocardiograph will be described. However, the housing structure according to the present invention can be applied to any electronic device.
図１は、本発明を適用可能な電子機器の一例としてのホルタ心電計の外観斜視図である。本実施形態に係るホルタ心電計１００は、円筒形電池を代表とする、高さ方向の両端面のような平行な２面に電極が存在する電池（以下、単に電池という）で駆動され、心電図データを着脱可能なメモリカードに記録する。そのため、ホルタ心電計１００は、電池およびメモリカードを交換するための開閉部１１０を有する。なお、電池は筐体内の電池収容部１８１に収容され、本実施形態では１本の電池を用いるものとするが、複数本が用いられてもよい。また、電池は一次電池でも二次電池でもよい。 FIG. 1 is an external perspective view of a Holter electrocardiograph as an example of an electronic apparatus to which the present invention can be applied. The Holter electrocardiograph 100 according to this embodiment is driven by a battery (hereinafter simply referred to as a battery) in which electrodes are present on two parallel surfaces such as both end faces in the height direction, typically a cylindrical battery, Record ECG data on a removable memory card. Therefore, the Holter electrocardiograph 100 has an opening / closing part 110 for exchanging the battery and the memory card. In addition, although a battery is accommodated in the battery accommodating part 181 in a housing | casing and shall use one battery in this embodiment, multiple pieces may be used. The battery may be a primary battery or a secondary battery.
開閉部１１０はその一端を軸受け部１４０によって筐体本体が有する軸に対して回動可能に取り付けられた蓋であり、矢印Ａで示すように開閉可能である。開閉部１１０には、第１のロック機構としての開閉レバー１２０と、第２のロック機構としてのロックレバー１３０が設けられている。 The opening / closing part 110 is a lid that is rotatably attached to one end of the opening / closing part 110 with respect to the shaft of the housing body by the bearing part 140, and can be opened and closed as indicated by an arrow A. The opening / closing part 110 is provided with an opening / closing lever 120 as a first locking mechanism and a locking lever 130 as a second locking mechanism.
開閉レバー１２０は矢印Ｂで示す方向に、図１に示すロック位置（第１の位置）とロック解除位置（第２の位置）との間で移動可能であり、また、開閉部１１０が閉じた状態においてはロック位置方向にバネで付勢されている。開閉レバー１２０はロック位置において開閉部１１０を閉じた状態に維持する。開閉部１１０は開閉レバー１２０がロック解除位置にあるときに開くことができる。開閉部１１０が開いた状態になると、電池収容部１８１やメモリカードスロットへのアクセスが可能になり、ユーザは電池収容部１８１に格納された電池１７０やメモリカードスロットに装着されたメモリカードを交換することができる。 The opening / closing lever 120 is movable in the direction indicated by the arrow B between the locking position (first position) and the unlocking position (second position) shown in FIG. 1, and the opening / closing part 110 is closed. In the state, it is biased by a spring in the lock position direction. The opening / closing lever 120 keeps the opening / closing part 110 closed in the locked position. The opening / closing part 110 can be opened when the opening / closing lever 120 is in the unlocked position. When the opening / closing part 110 is in an open state, the battery accommodating part 181 and the memory card slot can be accessed, and the user replaces the battery 170 stored in the battery accommodating part 181 and the memory card attached to the memory card slot. can do.
ロックレバー１３０は矢印Ｃで示す方向に、ロック位置（第３の位置）とロック解除位置（第４の位置）との間で移動可能である。ロックレバー１３０がロック位置にある場合、開閉レバー１２０はロック解除位置への移動が抑制され、ロックレバー１３０がロック解除位置にある場合にロック解除位置へ移動可能なように構成されている。 The lock lever 130 is movable in the direction indicated by the arrow C between a lock position (third position) and an unlock position (fourth position). When the lock lever 130 is in the lock position, the opening / closing lever 120 is configured to be inhibited from moving to the lock release position, and to move to the lock release position when the lock lever 130 is in the lock release position.
図２は、本実施形態のホルタ心電計１００の筐体構造を説明するための図である。（ａ）は開閉部１１０とは逆側からみた外観側面図、（ｂ）は（ａ）のM−M断面図、（ｃ）は電池１７０からの電源供給に係る構成を説明するための図である。 FIG. 2 is a view for explaining the housing structure of the Holter electrocardiograph 100 of the present embodiment. (A) is an external side view seen from the side opposite to the opening / closing part 110, (b) is a cross-sectional view taken along line MM in (a), and (c) is a diagram for explaining a configuration related to power supply from the battery 170. It is.
本実施形態のホルタ心電計１００は、特に、従来構成で必要だった電極板の支持部材を用いない構成とすることで、電池の高さ方向（電極面に直交する方向）における筐体の小型化を実現している。本実施形態では、電池収容部１８１を形成する筐体の剛性を高めることと、電極板の支持構成を改良することにより電極板の指示部材を省くことに成功した。 The Holter electrocardiograph 100 according to the present embodiment has a configuration in which the electrode plate support member that is necessary in the conventional configuration is not used, so that the housing in the height direction of the battery (the direction perpendicular to the electrode surface) can be obtained. Miniaturization is realized. In this embodiment, it succeeded in omitting the indication member of an electrode plate by improving the rigidity of the housing | casing which forms the battery accommodating part 181 and improving the support structure of an electrode plate.
まず、本実施形態のホルタ心電計１００は、電池１７０を電池収容部１８１に対して電池の高さ方向に挿入する構成とした。これにより、電池収容部１８１の大半を筐体本体で一体的に形成できるようになる。そのため、電池収容部１８１の底（または奥）側の電極板（図２では電極板１９３（第１の電極板））を筐体本体の内壁で直接支持するに足りる強度が実現できるため、図５における支持部材１７５が不要となる。 First, the Holter electrocardiograph 100 of the present embodiment has a configuration in which the battery 170 is inserted into the battery housing portion 181 in the height direction of the battery. As a result, most of the battery accommodating portion 181 can be formed integrally with the casing body. Therefore, it is possible to realize a strength sufficient to directly support the electrode plate (the electrode plate 193 (first electrode plate) in FIG. 2) on the bottom (or back) side of the battery housing portion 181 with the inner wall of the housing body. 5 is not necessary.
また、もう一方の電極板（ここでは正極用の電極板（第２の電極板））を、略平板状の開閉部１１０に内蔵することで、図５における支持部材１７４を省略することを可能とした。具体的には、開閉部１１０が基材として用いている金属板であるベースプレート１１０ｂを、正極用の電極板および回路基板への配線（図５における電極板１７１およびコード１７８）として利用することにより、支持部材１７４を不要としている。 Further, the other electrode plate (here, the positive electrode plate (second electrode plate)) is built in the substantially flat opening / closing part 110, whereby the support member 174 in FIG. 5 can be omitted. It was. Specifically, by using the base plate 110b, which is a metal plate used as the base material by the opening / closing part 110, as the electrode plate for the positive electrode and the wiring to the circuit board (the electrode plate 171 and the code 178 in FIG. 5). The support member 174 is unnecessary.
図３は、開閉部１１０付近の構成をより詳細に示した断面斜視図であり、（ａ）は開閉部がある状態を、（ｂ）は開閉部１１０を除いた状態を示している。また、図４（ａ）は図３における開閉部１１０を筐体内部側から見た状態を、（ｂ）はベースプレート１１０ｂとパッキン１１０ｃとの関係および正極の導通経路をそれぞれ示している。以下、図３〜図４をも用いて、本実施形態に係る筐体構造、特に電池から回路基板への導電経路に係る構造について詳細に説明する。 FIGS. 3A and 3B are cross-sectional perspective views showing a configuration in the vicinity of the opening / closing part 110 in more detail. FIG. 3A shows a state where the opening / closing part is present, and FIG. 3B shows a state where the opening / closing part 110 is removed. 4A shows the state of the opening / closing portion 110 in FIG. 3 as viewed from the inside of the housing, and FIG. 4B shows the relationship between the base plate 110b and the packing 110c and the conduction path of the positive electrode. Hereinafter, the housing structure according to the present embodiment, particularly the structure relating to the conductive path from the battery to the circuit board, will be described in detail with reference to FIGS.
電池収容部１８１に設けられる負極側の構成要素は、電極板１９３と、電極板１９３に接続されるコイルバネ１９２であり、従来の構成と同様である。ただし、上述の通り電極板１９３は筐体本体の内壁に直接支持される。なお、電極板１９３は実質的に筐体本体の内壁で支持されればよく、電極板１９３と筐体本体の内壁との間に他の部材が存在する構成を排除するものではない。また、電極板１９３はコード１９６とコネクタ１９９を通じて回路基板１９８の電源供給ラインの負極側に接続される。 The components on the negative electrode side provided in the battery housing part 181 are an electrode plate 193 and a coil spring 192 connected to the electrode plate 193, which are the same as the conventional configuration. However, as described above, the electrode plate 193 is directly supported on the inner wall of the housing body. The electrode plate 193 may be substantially supported by the inner wall of the housing body, and does not exclude a configuration in which another member exists between the electrode plate 193 and the inner wall of the housing body. The electrode plate 193 is connected to the negative electrode side of the power supply line of the circuit board 198 through the cord 196 and the connector 199.
一方、開閉部１１０を利用した正極側の導通構造は従来と大幅に異なる。本実施形態において開閉部１１０は、剛性のある導体材料からなる板状の基材（例えば金属板）であるベースプレート１１０ｂと、ベースプレート１１０ｂの上に取り付けられたカバー１１０ａと、ベースプレート１１０ｂを覆うように形成されたパッキン１１０ｃとから構成されている。そして、カバー１１０ａがベースプレート１１０ｂとの間に形成する内部空間に開閉レバー１２０、爪部１２１、ロックレバー１３０などの可動部品や、バネなどが収納されている。 On the other hand, the conductive structure on the positive electrode side using the opening / closing part 110 is significantly different from the conventional one. In the present embodiment, the opening / closing part 110 covers a base plate 110b that is a plate-like base material (for example, a metal plate) made of a rigid conductive material, a cover 110a attached on the base plate 110b, and the base plate 110b. It is comprised from the formed packing 110c. In the internal space formed between the cover 110a and the base plate 110b, movable parts such as the opening / closing lever 120, the claw portion 121, and the lock lever 130, and springs are accommodated.
パッキン１１０ｃは、開閉部１１０の周囲を通じて外部から液体や粉塵などが侵入することを防ぐために必要に応じて設けられる。本実施形態においては、ベースプレート１１０ｂにパッキン１１０ｃを形成するシリコン樹脂をインサート成形することにより、ベースプレート１１０ｂを被覆するようにパッキン１１０ｃを設けている（図４（ｂ）参照）。 The packing 110c is provided as necessary to prevent liquid or dust from entering from the outside through the periphery of the opening / closing part 110. In the present embodiment, the packing 110c is provided so as to cover the base plate 110b by insert molding a silicon resin for forming the packing 110c on the base plate 110b (see FIG. 4B).
ただし、ベースプレート１１０ｂを正極用の電極板および、回路基板１９８の電源供給ラインの正極側と電池１７０の正極とを電気的に接続する配線として利用するため、パッキン１１０ｃは、図４（ａ），（ｂ）に示すように、電極板１９３に対向する、電池１７０の正極と接する部分と、回路基板１９８に実装されているプローブ電極１９４の端子１９４１と接する部分１１０１については設けられない。また、本実施形態では、メモリカードスロット１９７に対向する部分についてもパッキン１１０ｃを設けないようにしているが、これも必須ではない。なお、パッキン１１０ｃに求められる性能（防塵や液体侵入防止など）が実現できれば、ベースプレート１１０ｂの一部を覆うようにパッキン１１０ｃを形成しなくてもよい。また、パッキン１１０ｃをインサート成形以外の方法で設けてもよい。 However, since the base plate 110b is used as a wiring for electrically connecting the positive electrode plate and the positive electrode side of the power supply line of the circuit board 198 and the positive electrode of the battery 170, the packing 110c is formed as shown in FIG. As shown in (b), the portion that contacts the positive electrode of the battery 170 facing the electrode plate 193 and the portion 1101 that contacts the terminal 1941 of the probe electrode 194 mounted on the circuit board 198 are not provided. Further, in this embodiment, the packing 110c is not provided in the portion facing the memory card slot 197, but this is not essential. Note that the packing 110c may not be formed so as to cover a part of the base plate 110b if the performance required for the packing 110c (such as dust prevention and liquid intrusion prevention) can be realized. Moreover, you may provide packing 110c by methods other than insert molding.
プローブ電極１９４は、回路基板１９８とベースプレート１１０ｂとを電気的に接続するために設けられている。開閉部１１０が閉じた状態において確実に接続を行うため、プローブ電極１９４の端子１９４１にはコンタクトプローブのようにスプリングが内蔵され、開閉部１１０の方向に付勢されている。そして、開閉部１１０を閉じられた際にベースプレート１１０ｂの部分１１０１で端子１９４１が押し込まれるように端子１９４１のストローク量とプローブ電極１９４の配置が決定されている。端子１９４１が３つ設けてあるのは、接続を確実に行うためである。 The probe electrode 194 is provided to electrically connect the circuit board 198 and the base plate 110b. A spring is built in the terminal 1941 of the probe electrode 194 like a contact probe and biased in the direction of the opening / closing part 110 in order to make a reliable connection when the opening / closing part 110 is closed. Then, the stroke amount of the terminal 1941 and the arrangement of the probe electrode 194 are determined so that the terminal 1941 is pushed in the portion 1101 of the base plate 110b when the opening / closing part 110 is closed. The reason why three terminals 1941 are provided is to ensure connection.
開閉部１１０には爪部１２１が設けられている（図３（ａ）および図４（ａ）参照）。爪部１２１は、開閉レバー１２０とともに矢印Ｂ（図１）方向に移動する部材であり、開閉部１１０が閉じた状態では、その先端部分が筐体本体の内面に設けられた溝１０１に入り込むことで、開閉部１１０が閉じた状態を保持する（図３）。バネ１２２は開閉レバー１２０と爪部１２１とを逆方向に付勢し、爪部１２１が開閉レバー１２０と独立して矢印Ｂ方向に移動することを可能としながら、爪部１２１を溝１０１側に付勢している。バネ１２２の付勢により、開閉部１１０が閉じられた際に爪部１２１が溝１０１に入り込んで開閉部１１０を閉状態に保持する。 The opening / closing part 110 is provided with a claw part 121 (see FIGS. 3A and 4A). The claw portion 121 is a member that moves in the direction of arrow B (FIG. 1) together with the opening / closing lever 120. When the opening / closing portion 110 is closed, the tip portion of the claw portion 121 enters the groove 101 provided on the inner surface of the housing body. Thus, the closed state of the opening / closing part 110 is maintained (FIG. 3). The spring 122 urges the opening / closing lever 120 and the claw portion 121 in the reverse direction, allowing the claw portion 121 to move in the direction of arrow B independently of the opening / closing lever 120, and moving the claw portion 121 toward the groove 101. Energized. When the opening / closing part 110 is closed by the bias of the spring 122, the claw part 121 enters the groove 101 and holds the opening / closing part 110 in the closed state.
開閉部１１０が閉じられると、コイルバネ１９２が電池１７０を正極方向（開閉部１１０方向）に押しつけ、電池１７０の正極がベースプレート１１０ｂに接触する。また、プローブ電極１９４の端子１９４１もベースプレート１１０ｂに押圧される。これにより、導通手段としてのベースプレート１１０ｂが、電池１７０の正極とプローブ電極１９４の端子１９４１とを電気的に導通する。これにより、回路基板１９８の電源供給ラインが、電池１７０の正極、負極に接続され、回路の動作が可能になる。 When the opening / closing part 110 is closed, the coil spring 192 presses the battery 170 in the positive electrode direction (the opening / closing part 110 direction), and the positive electrode of the battery 170 contacts the base plate 110b. Further, the terminal 1941 of the probe electrode 194 is also pressed against the base plate 110b. As a result, the base plate 110b serving as a conducting means electrically conducts the positive electrode of the battery 170 and the terminal 1941 of the probe electrode 194. Thereby, the power supply line of the circuit board 198 is connected to the positive electrode and the negative electrode of the battery 170, and the circuit can be operated.
以上説明したように、本実施形態によれば、筐体本体と筐体の開閉部とで電極板を支持するように構成したので、従来必要だった電極板の支持部材を省くことができ、電池の高さ方向における筐体の大きさを削減することが可能になる。 As described above, according to the present embodiment, since the electrode plate is supported by the housing body and the opening / closing portion of the housing, it is possible to omit the electrode plate supporting member that has been conventionally required, It is possible to reduce the size of the casing in the height direction of the battery.
また、開閉部がもともと備えている基材を導電材料で形成して電極板および回路基板への導電部材として用いることにより、電極板や配線等を用いる必要が無いため、部品点数およびコストの削減はもちろん、装置の小型化の上でも有利である。なお、開閉部の基材を導通部材として流用することは必須でなく、例えば開閉部の基材が絶縁体で形成される場合に、電極板１９３に対向する部分と端子１９４１と接する部分とを電気的に接続する部材（例えば金属板）を別途設けてもよい。 In addition, since the base material originally provided in the opening / closing part is made of a conductive material and used as a conductive member for the electrode plate and circuit board, there is no need to use an electrode plate or wiring, thereby reducing the number of parts and cost Of course, it is also advantageous in reducing the size of the apparatus. In addition, it is not indispensable to divert the base material of the opening / closing part as a conductive member. For example, when the base material of the opening / closing part is formed of an insulator, a part facing the electrode plate 193 and a part in contact with the terminal 1941 are provided. A member (for example, a metal plate) that is electrically connected may be provided separately.
なお、電池を複数用いる機器の場合、電池を一列に並べて使用する場合には上述した構成をそのまま適用可能である。一方、電池が並列接続される場合には、上述した構成を複数列に拡張すれば良い。上述の構成が電池の配列や接続方法に応じて容易に拡張可能あることは当業者にとって容易に理解される。 In the case of a device using a plurality of batteries, the configuration described above can be applied as it is when the batteries are used in a line. On the other hand, when the batteries are connected in parallel, the above-described configuration may be extended to a plurality of rows. Those skilled in the art will readily understand that the above-described configuration can be easily expanded according to the arrangement and connection method of the batteries.
また、上述の実施形態では、負極の電極板１９３を筐体本体の内壁で直接支持する構造について説明した。しかしながら、正極側の導通構造のみの採用によっても筐体の小型化は実現可能であるため、負極の電極板１９３を筐体本体の内壁で支持する構成は本発明に必須ではない。 In the above-described embodiment, the structure in which the negative electrode plate 193 is directly supported by the inner wall of the housing body has been described. However, since the housing can be downsized by adopting only the positive-side conductive structure, the configuration in which the negative electrode plate 193 is supported by the inner wall of the housing body is not essential to the present invention.
