Description

本発明は、携帯用の電子機器に電池を収納するための構造に関する。詳しくは安定した電源供給を可能とし、省スペースで電池交換容易な電池収納部に関する。また、そのような電池収納部を備えた電子機器に関する。 The present invention relates to a structure for storing a battery in a portable electronic device. More specifically, the present invention relates to a battery storage unit that enables stable power supply, and saves space and allows easy battery replacement. Moreover, it is related with the electronic device provided with such a battery accommodating part.

従来、携帯用等の電子機器は、駆動手段として電池（乾電池）を利用し、複数の電池を直列に接続して所望の電源電圧を確保している。
例えば２本の電池を直列で利用する場合は、一方の電池のプラス電極と他方の電池のマイナス電極とを接触させ、一方の電池のマイナス電極に接触させた金属端子と、他方の電池のプラス電極に接触させた金属端子の各々を電子機器の電源端子に接続する。
このとき、電子機器に安定した電源供給をするには、電池の各接触部が電子機器に加わる振動や衝撃によって離れることなく接触していることが必要となる。 2. Description of the Related Art Conventionally, portable electronic devices use a battery (dry battery) as a driving unit and connect a plurality of batteries in series to ensure a desired power supply voltage.
For example, when two batteries are used in series, the positive electrode of one battery is in contact with the negative electrode of the other battery, the metal terminal in contact with the negative electrode of one battery, and the positive electrode of the other battery. Each metal terminal brought into contact with the electrode is connected to a power supply terminal of the electronic device.
At this time, in order to stably supply power to the electronic device, it is necessary that the contact portions of the battery are in contact with each other without being separated by vibration or impact applied to the electronic device.

また、これら電池電極や金属端子は、時間放置しておくとその表面に酸化皮膜が形成し、これによって電池電極や金属端子の接触抵抗が増大する問題が起ることが知られている。
ただし、この問題は金属端子と電池電極の接触部よりも、電池電極同士の接触部に生じやすい傾向がある。その理由は、一般に用いられる金属端子の材質は電池電極の材質よりも硬いため、電池電極と金属端子の接触部にはこれらが互いに擦り合うことで酸化皮膜を除去するセルフクリーニング効果が得られるが、電池同士による同じ材質の接触部にはセルフクリーニング効果が期待できないためと考えられている。 Further, it is known that when these battery electrodes and metal terminals are left for a period of time, an oxide film is formed on the surface thereof, thereby causing a problem that the contact resistance of the battery electrodes and metal terminals increases.
However, this problem tends to occur more easily at the contact portion between the battery electrodes than at the contact portion between the metal terminal and the battery electrode. The reason is that the material of the metal terminal generally used is harder than the material of the battery electrode, so that the contact portion between the battery electrode and the metal terminal rubs against each other to provide a self-cleaning effect that removes the oxide film. It is considered that a self-cleaning effect cannot be expected at the contact portion of the same material between the batteries.

特許文献１には、電池同士の接触をなくした電池収納部として、電池収納部の中間に突起部を設け、この突起部（壁）に中間電極を装着し、複数の電池を個々に保持することが開示されている。 In Patent Document 1, as a battery storage unit that eliminates contact between batteries, a protrusion is provided in the middle of the battery storage unit, an intermediate electrode is attached to the protrusion (wall), and a plurality of batteries are individually held. It is disclosed.

特開２００５−１７４６２８JP-A-2005-174628

しかしながら、このように電池と電池の間に突起部（壁）とコイル部を含む中間電極とを設けると、その分だけ電池収納スペースは大きくなり、これを備える電子機器は大型化して携帯しづらいものとなる。
さらに、各々の電池はコイル部を有する電極を用いて個別に付勢されているので、電池の装填および取外しの際は電池ごとにコイル部を縮める方向へ力をかける必要があり、電池交換がしづらくなる。 However, when the protrusions (walls) and the intermediate electrode including the coil portion are provided between the batteries as described above, the battery storage space increases accordingly, and an electronic device including the space is enlarged and difficult to carry. It will be a thing.
Furthermore, since each battery is individually energized using an electrode having a coil portion, it is necessary to apply a force in the direction of shrinking the coil portion for each battery when the battery is loaded and removed. It becomes difficult.

本発明は係る課題を解決して、酸化皮膜によって生じる接触抵抗の増大を防止し、安定した電源供給を可能としながら、省スペースで電池交換容易な電池収納部を提供するものである。また、そのような電池収納部を備えた電子機器を提供することを目的とする。 The present invention solves such a problem, and provides a battery housing portion that can save space and can be easily replaced while preventing an increase in contact resistance caused by an oxide film and enabling stable power supply.

まず、図１、図２を用いて、本発明の電池収納部を備えた電子機器の一例を説明する。
図１は電子機器1の正面外観図であり、図２は図１の右側から見た側面外観図である。 First, an example of an electronic apparatus provided with the battery storage unit of the present invention will be described with reference to FIGS.
1 is a front external view of the electronic apparatus 1, and FIG. 2 is a side external view as viewed from the right side of FIG.

スイッチ４０のオン／オフ情報は、電子機器１から送信され、例えば制御対象が車載用クレーンであるならばクレーンの前後の位置や傾きを制御する信号となる。 The electronic device 1 is an operation unit of a wireless control system that wirelessly controls various industrial devices such as an in-vehicle crane and an automated guided vehicle. An operator switches, for example, while holding the battery chamber 101 part with one hand. Operate 40 on / off.

これら逆向き防止用切欠部５１８や舌片５１７ａ，５１７ｂによって、電池ホルダ５０は常に正しい向きで電池室１０１に収納される。その仕組みについては後で説明する。 Further, the substrate 511 of the battery holder main body 51 is formed with a notch portion 518 for preventing the reverse direction by cutting one corner of one end portion into a rectangle, and the outer end portion of the partition portion 517 is formed as shown in FIG. ) To the left and right, and tongue pieces 517a and 517b are formed.
The battery holder 50 is always housed in the battery chamber 101 in the correct orientation by the reverse-direction preventing cutout 518 and the tongue pieces 517a and 517b. The mechanism will be described later.

次に、中間端子５２１，５２２の形状を説明する。
図７（ａ）は中間端子５２１，５２２の第１の実施形態の平面図であり、図７（ｂ）は図７（ａ）のＦ−Ｆ矢印方向に見た断面図である。
中間端子５２１，５２２は、１本の針金をひとつの平面上で曲げて作られ、まず針金をコ字状に曲げ、さらにその中央部分を中心に向かって略Ｕ字状に曲げてＵ字状部５２ｂが形成され、さらに両方の端部の各々を中心側へＬ字状に曲げて係止部５２ａが形成されている。
なお、係止部５２ａは、中間端子５２１，５２２を取付ける相手の形状の応じて、中心側と逆の方向へＬ字状に曲げて形成しても良い。
また、中間端子５２１，５２２の針金は、先に述べたコイル状端子３１１，３１２と同じ形状及び材質の針金を用いることができる。
以上のとおり、中間端子５２１，５２２は１本の針金を曲げるだけで容易に作ることができる。 Next, the shape of the intermediate terminals 521 and 522 will be described.
FIG. 7A is a plan view of the first embodiment of the intermediate terminals 521 and 522, and FIG. 7B is a cross-sectional view as seen in the direction of the arrow FF in FIG. 7A.
The intermediate terminals 521 and 522 are made by bending a single wire on a single plane. First, the wire is bent in a U-shape, and further, the central portion is bent in a substantially U-shape toward the center. A portion 52b is formed, and each of both end portions is bent in an L shape toward the center to form a locking portion 52a.
The locking part 52a may be formed by bending it in an L-shape in the direction opposite to the center side according to the shape of the counterpart to which the intermediate terminals 521 and 522 are attached.
The wires of the intermediate terminals 521 and 522 can be the same shape and material as the coiled terminals 311 and 312 described above.
As described above, the intermediate terminals 521 and 522 can be easily made by simply bending one wire.

次に、これら電池ホルダ本体５１と中間端子５２１，５２２を組立てて電池ホルダ５０とする過程を説明する。 Next, the process of assembling the battery holder main body 51 and the intermediate terminals 521 and 522 into the battery holder 50 will be described.

まず、中間端子５２１は、次のようにして電池ホルダ本体５１の上面に取付けられる。
中間端子５２１は全体に弾性を有しているので、２つの係止部５２ａの各々を外方に開き、係止部５２ａを電池ホルダ本体５１の上面側にある係止穴５１４の位置に合せて中間端子５２１を通常の状態に戻せば、２つの係止部５２ａの各々は２つの係止穴５１４の各々に差込まれ、中間端子５２１は電池ホルダ本体５１に係止される。
このとき中間端子５２１は、電池ホルダ本体５１の上面にある２つの溝５１５に挟まり、溝５１５の幅を中間端子５２１を構成する針金の直径より大きく設定することで、溝５１５の幅の範囲でいわゆるガタを持つ。
また、係止穴５１４の大きさを中間端子５１１を構成する針金の直径より大きくしているので、係止部５２ａを係止穴５１４へ挿入することは容易にできる。
このようにして、中間端子５２１は係止部５２ａを回動中心として電池ホルダ本体５１へ揺動可能に係止される。 First, the intermediate terminal 521 is attached to the upper surface of the battery holder body 51 as follows.
Since the intermediate terminal 521 has elasticity as a whole, each of the two locking portions 52a is opened outward, and the locking portion 52a is aligned with the position of the locking hole 514 on the upper surface side of the battery holder body 51. When the intermediate terminal 521 is returned to the normal state, each of the two locking portions 52 a is inserted into each of the two locking holes 514, and the intermediate terminal 521 is locked to the battery holder body 51.
At this time, the intermediate terminal 521 is sandwiched between the two grooves 515 on the upper surface of the battery holder body 51, and the width of the groove 515 is set larger than the diameter of the wire constituting the intermediate terminal 521, so that the width of the groove 515 is reduced. It has so-called backlash.
Further, since the size of the locking hole 514 is larger than the diameter of the wire constituting the intermediate terminal 511, the locking portion 52a can be easily inserted into the locking hole 514.
In this way, the intermediate terminal 521 is swingably locked to the battery holder body 51 with the locking portion 52a as the center of rotation.

同様にして、中間端子５２２は、電池ホルダ本体５１の下面側に取付けられ、係止部５２ａを回動中心として電池ホルダ本体５１へ揺動可能に係止される。 Similarly, the intermediate terminal 522 is attached to the lower surface side of the battery holder main body 51 and is swingably locked to the battery holder main body 51 with the locking portion 52a as a rotation center.

以上のとおり、電池ホルダ本体５１への中間端子５２１，５２２の取付けは、中間端子５２１，５２２の弾性を利用して容易にできる。
また、中間端子５２１，５２２は電池ホルダ本体５１に係止されているので、組立て後に外れることはない。よって、電池ホルダ５０は取扱いやすいものとなる。 As described above, the intermediate terminals 521 and 522 can be easily attached to the battery holder main body 51 using the elasticity of the intermediate terminals 521 and 522.
Further, since the intermediate terminals 521 and 522 are locked to the battery holder main body 51, they are not detached after assembly. Therefore, the battery holder 50 is easy to handle.

上述の電池ホルダ５０には、次のようにして４本の電池が装填される。
図５を用いて、電池５４１，５４２，５４３，５４４が電池ホルダ５０に装填される様子を説明する。 Four batteries are loaded into the battery holder 50 described above.
The manner in which the batteries 541, 542, 543, and 544 are loaded in the battery holder 50 will be described with reference to FIG.

電池５４１，５４２，５４３，５４４の各電池は、電池ホルダ本体５１の表面に記されている正しい電池の向き（極性）に従って、次のようにして装填される。
まず、電池５４１，５４２は、図５の左奥側から電池ホルダ本体５１の所定の位置（左側に電池５４１、右側に電池５４２）に押し込むことで、弾性を持つ保持ツメ５１３を開きながら電池ホルダ本体５１に装填される。
このとき、中間端子５２１のＵ字状部５２ｂは電池５４１のプラス電極と電池５４２のマイナス電極とで挟まれ、電池５４１と電池５４２は中間端子５２１を介した直列電池としてふるまう。 The batteries 541, 542, 543, and 544 are loaded in the following manner according to the correct battery orientation (polarity) indicated on the surface of the battery holder body 51.
First, the batteries 541 and 542 are pushed into predetermined positions (the battery 541 on the left side and the battery 542 on the right side) from the left back side in FIG. 5 to open the battery holder 513 while opening the elastic holding claw 513. The main body 51 is loaded.
At this time, the U-shaped portion 52b of the intermediate terminal 521 is sandwiched between the positive electrode of the battery 541 and the negative electrode of the battery 542, and the battery 541 and the battery 542 behave as a series battery via the intermediate terminal 521.

同様に、電池５４３，５４４は、図５の右手前側から電池ホルダ本体５１の所定の位置（左側に電池５４４、右側に電池５４３）に押し込むことで、弾性を持つ保持ツメ５１３を開きながら電池ホルダ本体５１に装填される。
このとき、中間端子５２２のＵ字状部５２ｂは電池５４３のプラス電極と電池５４４のマイナス電極とで挟まれ、電池５４３と電池５４４は中間端子５２２を介した直列電池としてふるまう。 Similarly, the batteries 543 and 544 are pushed into a predetermined position (the battery 544 on the left side and the battery 543 on the right side) from the right front side of FIG. 5 to open the battery holder 513 while opening the elastic holding claw 513. The main body 51 is loaded.
At this time, the U-shaped portion 52 b of the intermediate terminal 522 is sandwiched between the positive electrode of the battery 543 and the negative electrode of the battery 544, and the battery 543 and the battery 544 behave as a series battery via the intermediate terminal 522.

装填された電池５４１，５４２，５４３，５４４は、仕切り部５１６から仕切り部５１７までの距離が電池２本分の長さより長い距離に設定されているので、保持ツメ５１３によって電池の長さ方向へ動くように保持される。 In the loaded batteries 541, 542, 543, and 544, the distance from the partition portion 516 to the partition portion 517 is set to be longer than the length of two batteries. Holds to move.

なお、装填された電池５４１，５４２，５４３，５４４を電池ホルダ本体５１から取外すときは、壁５１２の各電池の両脇部分に設けた電池取出し用切欠部５１９に指を入れて電池をつまみ、装填した方向と逆方向に引くことで容易に取外せる。 When removing the loaded batteries 541, 542, 543, and 544 from the battery holder main body 51, the fingers are put into the battery removal notches 519 provided on both sides of each battery on the wall 512, and the battery is pinched. It can be easily removed by pulling in the direction opposite to the loading direction.

以上のとおり、電池ホルダ５０は４本の電池を電池の長さ方向に２本ずつ、基板５１１の上下の面に２列に並べて保持し、電池ホルダ５０への電池の装填および取外しは容易に行うことができる。
さらに、電池ホルダ５０は電池室１０１に収納され、電池室１０１は電子機器１の駆動手段である電源となり、電源電流はマイナス電圧端子となるコイル状端子３１１→電池５４１→中間端子５２１→電池５４２→板バネ端子２０１→電池５４３→中間端子５２２→電池５４４→プラス電圧端子となるコイル状端子３１２の順に各部が接触する経路で流れる。 As described above, the battery holder 50 holds four batteries in the length direction of the battery in two rows on the upper and lower surfaces of the substrate 511 so that the battery can be easily loaded and removed from the battery holder 50. It can be carried out.
Further, the battery holder 50 is housed in the battery chamber 101, and the battery chamber 101 serves as a power source that is a driving means of the electronic device 1, and the power source current is a coiled terminal 311 that serves as a negative voltage terminal → the battery 541 → the intermediate terminal 521 → the battery 542. The plate spring terminal 201, the battery 543, the intermediate terminal 522, the battery 544, and the coiled terminal 312 in the order of a positive voltage terminal flow in a path in which the respective parts come into contact with each other.

このとき、中間端子５２１を挟んだ電池５４１と電池５４２の直列電池は、一方にあるコイル状端子３１１と他方にある板バネ端子２０１とで両端を付勢され、また同様に、中間端子５２２を挟んだ電池５４３と電池５４４の直列電池は、一方にあるコイル状端子３１２と他方にある板バネ端子２０１とで両端を付勢される。
よって、電子機器１が動いた場合に生じる直列電池の長さ方向の動きは、対峙するコイル状端子３１１と板バネ端子２０１のそれぞれ、および対峙するコイル状端子３１２と板バネ端子２０１のそれぞれが相反して伸び縮みして吸収される。 At this time, the series battery of the battery 541 and the battery 542 sandwiching the intermediate terminal 521 is biased at both ends by the coiled terminal 311 on one side and the leaf spring terminal 201 on the other side. The series battery of the sandwiched battery 543 and battery 544 is biased at both ends by a coiled terminal 312 on one side and a leaf spring terminal 201 on the other side.
Therefore, the movement in the length direction of the series battery that occurs when the electronic device 1 moves is that the coiled terminal 311 and the leaf spring terminal 201 facing each other, and the coiled terminal 312 and the leaf spring terminal 201 facing each other are In contrast, it stretches and shrinks and is absorbed.

また、中間端子５２１，５２２は、直列電池の長さ方向の動きに対して以下のように変形し、電池の動きに追従する。
中間端子５２１と中間端子５２２は同じ形状なので、例として中間端子５２１が変形する様子を説明する。
図８は電池５４１と電池５４２と中間端子５２１を図５の左奥側から見た図であり、図８（ａ）は平常時を示し、図８（ｂ）は電池５４１，５４２が電池ホルダ本体５１の一方の側に動いた場合を示し、図８（ｃ）は電池５４１，５４２が電池ホルダ本体５１の他方の側に動いた場合を示す。
図８のとおり、電池５４１，５４２が動いた場合でも、針金からなる中間端子５２１は全体に弾性を有しているので、そのＵ字状部５１ｃは常に電池電極の面と平行に位置し、電池の動きに追従するように変形する。 Further, the intermediate terminals 521 and 522 are deformed as follows with respect to the movement in the length direction of the series battery, and follow the movement of the battery.
Since the intermediate terminal 521 and the intermediate terminal 522 have the same shape, how the intermediate terminal 521 is deformed will be described as an example.
8 is a view of the battery 541, the battery 542, and the intermediate terminal 521 as viewed from the left rear side in FIG. 5, FIG. 8 (a) shows a normal state, and FIG. 8 (b) shows the batteries 541 and 542 in the battery holder. FIG. 8C shows the case where the batteries 541 and 542 are moved to the other side of the battery holder main body 51.
As shown in FIG. 8, even when the batteries 541 and 542 move, the intermediate terminal 521 made of a wire has elasticity as a whole, so that the U-shaped portion 51c is always positioned parallel to the surface of the battery electrode, Deforms to follow the movement of the battery.

以上のとおり、電池室１０１は、直列電池の両端をバネ性を有する端子で付勢し、直列電池が電池の長さ方向へ動くように保持されているので、以下の効果が得られる。
まず、電源電流が流れるコイル状端子３１１→電池５４１→中間端子５２１→電池５４２→板バネ端子２０１の経路、および板バネ端子２０１→電池５４３→中間端子５２２→電池５４４→コイル状端子３１２の経路において、電子機器１に振動や衝撃が加わっても直列電池の動きを吸収できるので電流が途切れないように各部の接触を保つことができる。
ここで、直列電池の一端のみをバネ性のある端子で付勢した場合は、直列電池が動くと電源電流が途切れてしまうので直列電池が動かないように端子のバネ圧を高める必要がある。しかし本発明の電池室１０１は直列電池を動くように保持するので端子のバネ圧を高める必要がない。よって本発明の電池室１０１は、電池に無理な力をかけないので電池を故障させることがないとともに、電池蓋２０を閉めやすくできるので電池交換を容易にできる。 As described above, since the battery chamber 101 urges both ends of the series battery with the terminals having the spring property and the series battery is held so as to move in the length direction of the battery, the following effects are obtained.
First, a coil-shaped terminal 311 through which a power supply current flows → battery 541 → intermediate terminal 521 → battery 542 → leaf spring terminal 201 and leaf spring terminal 201 → battery 543 → intermediate terminal 522 → battery 544 → coiled terminal 312 In this case, even if vibration or impact is applied to the electronic device 1, the movement of the series battery can be absorbed, so that the contact of each part can be maintained so that the current is not interrupted.
Here, when only one end of the series battery is energized with a terminal having a spring property, the power supply current is interrupted when the series battery moves, so it is necessary to increase the spring pressure of the terminal so that the series battery does not move. However, since the battery chamber 101 of the present invention holds the series battery so as to move, it is not necessary to increase the spring pressure of the terminal. Therefore, the battery chamber 101 of the present invention does not apply excessive force to the battery, so that the battery is not damaged and the battery lid 20 can be easily closed, so that the battery can be easily replaced.

またこれに加えて電池室１０１は、直列電池を構成する電池の間に針金からなる中間端子５２１，５２２を配置することで、以下の効果が得られる。
中間端子５２１，５２２と電池電極との接触部は、直列電池が電池の長さ方向へ動くように保持されているので、中間端子５２１，５２２と電池電極が互いに擦り合うことによって酸化膜が除去されるセルフクリーニング効果が得られる。同様に直列電池の両端と各端子の接触部にもセルフクリーニング効果が得られるので、電池５４１，５４２，５４３，５４４はすべての電池電極でセルフクリーニング効果が得られる。よって電池室１０１は電池電極と端子の各接触部に接触抵抗が増大する問題が生じない。
このとき、直列に並べた電池と電池の間に中間端子５２１，５２２を挟んでも、電池間の距離は針金の直径分でしかない小さい距離ですむので、電池室１０１は省スペースなものにできる。 In addition to this, the battery chamber 101 has the following effects by arranging the intermediate terminals 521 and 522 made of wire between the batteries constituting the series battery.
Since the contact portion between the intermediate terminals 521 and 522 and the battery electrode is held so that the series battery moves in the length direction of the battery, the oxide film is removed by rubbing the intermediate terminals 521 and 522 with the battery electrode. Self-cleaning effect is obtained. Similarly, since the self-cleaning effect can be obtained at the contact portion between both ends of the series battery and each terminal, the batteries 541, 542, 543, and 544 can obtain the self-cleaning effect with all the battery electrodes. Therefore, the battery chamber 101 does not have a problem that contact resistance increases at each contact portion between the battery electrode and the terminal.
At this time, even if the intermediate terminals 521 and 522 are sandwiched between the batteries arranged in series, the distance between the batteries can be as small as the wire diameter, so the battery chamber 101 can be made space-saving. .

よって、電子機器１は常に安定した電源供給を受けられるとともに、小型にできる。
また、予備の電池ホルダ５０を用意し、電池ホルダ５０を交換することで複数の電池を一括して短時間に交換できるので、電子機器１は電池交換のために動作停止する時間を短くできる。 Therefore, the electronic device 1 can always receive a stable power supply and can be downsized.
In addition, since a plurality of batteries can be replaced in a short time by preparing a spare battery holder 50 and replacing the battery holder 50, the electronic device 1 can shorten the time during which the operation is stopped for battery replacement.

先に述べた電池ホルダ本体５１にある逆向き防止用切欠部５１８や舌片５１７ａ，５１７ｂによって、電池ホルダ５０は常に正しい向きで電池室１０１に収納される。その仕組みを以下に説明する。 The battery holder 50 is always housed in the battery chamber 101 in the correct orientation by the reverse prevention cutout 518 and the tongue pieces 517a and 517b in the battery holder main body 51 described above. The mechanism will be described below.

まず、電池ホルダ５０の上下方向に着目して説明する。
図１１は図２のＣ−Ｃ線の断面図である。
凸形状である端子板３０の逆向き防止用突出部３０１は、電池室１０１に電池ホルダ５０を正しい向きで挿入されたとき、凹形状である電池ホルダ本体５１の逆向き防止用切欠部５１８と噛合う。
仮に、電池ホルダ５０を電池ホルダ５０の上下方向に対して逆向きで電池室１０１に挿入したとき、逆向き防止用突出部３０１は電池ホルダ本体５１の一端の角にぶつかるので、電池ホルダ５０は電池室１０１に収納されない。
つまり、電池ホルダ５０は、電池ホルダ５０の上下方向を誤って電池室１０１に収納されることはない。 First, the description will be made focusing on the vertical direction of the battery holder 50.
11 is a cross-sectional view taken along the line CC of FIG.
The protrusion 301 for preventing the reverse direction of the terminal plate 30 having a convex shape and the notch 518 for preventing the reverse direction of the battery holder body 51 having a concave shape when the battery holder 50 is inserted into the battery chamber 101 in the correct orientation. Mesh.
If the battery holder 50 is inserted into the battery chamber 101 in the opposite direction with respect to the vertical direction of the battery holder 50, the reverse-preventing protrusion 301 hits the corner of one end of the battery holder body 51. It is not stored in the battery chamber 101.
That is, the battery holder 50 is not stored in the battery chamber 101 by mistake in the vertical direction of the battery holder 50.

次に、電池の長さ方向に着目して説明する。
図１２は図１のＢ−Ｂ線の断面を示した図である。ただし、電池ホルダ５０は省略してケース１０のみの断面を示してある。
図１３は図１２のＤ−Ｄ線およびＥ−Ｅ線の断面を示した図である。ただし、電池蓋２０と電池ホルダ５０は省略して電池蓋２０付近のケース１０のみの断面を示してある。
１０２ａ，１０２ｂはケース１０の内側に突設されたレール状のガイド用突出部であり、ガイド用突出部１０２ａ，１０２ｂは図２のＤ−Ｄ線およびＥ−Ｅ線の位置の２箇所に設けられている。また、ガイド用突出部１０２ａ，１０２ｂは電池室１０１の奥から長手方向へ直線状に延伸し、電池蓋２０に接する手前まで設けられている。
ガイド用突出部１０２ａ，１０２ｂは、電池室１０１に電池ホルダ５０を収納する際に、電池ホルダ５０の動きを規制して収納位置をガイドする。 Next, a description will be given focusing on the length direction of the battery.
12 is a cross-sectional view taken along line BB in FIG. However, the battery holder 50 is omitted and only the case 10 is shown in cross section.
13 is a cross-sectional view taken along line DD and line EE in FIG. However, the battery lid 20 and the battery holder 50 are omitted, and only a cross section of the case 10 near the battery lid 20 is shown.
Reference numerals 102a and 102b denote rail-shaped guide protrusions protruding from the inside of the case 10, and the guide protrusions 102a and 102b are provided at two positions of the DD line and the EE line in FIG. It has been. Further, the guide protrusions 102 a and 102 b extend linearly from the back of the battery chamber 101 in the longitudinal direction, and are provided up to a position in contact with the battery lid 20.
When the battery holder 50 is stored in the battery chamber 101, the guide protrusions 102a and 102b regulate the movement of the battery holder 50 and guide the storage position.

図１４は、図１の下から見た図であり、電池蓋２０を開いた状態の一部分を示している。
図１４のとおり、電池室１０１に電池ホルダ５０を正しい向きで挿入したとき、電池ホルダ本体５１の他方にある舌片５１７ａ，５１７ｂはガイド用突出部１０２ｂの端部を覆うこととなる。
仮に、電池ホルダ５０を電池の長さ方向に対して逆向きで電池室１０１に挿入したとき、ガイド用突出部１０２ａまたはガイド用突出部１０２ｂのいずれかの端部は舌片５１７ａ，５１７ｂにぶつかるので、電池ホルダ５０は電池室１０１に収納されない。
つまり、電池ホルダ５０は、電池ホルダ５０の電池の長さ方向を誤って電池室１０１に収納されることはない。 FIG. 14 is a view as seen from the bottom of FIG. 1 and shows a part of the battery lid 20 in an opened state.
As shown in FIG. 14, when the battery holder 50 is inserted into the battery chamber 101 in the correct orientation, the tongue pieces 517a and 517b on the other side of the battery holder main body 51 cover the end portion of the guide protrusion 102b.
If the battery holder 50 is inserted into the battery chamber 101 in the direction opposite to the battery length direction, either end of the guide protrusion 102a or the guide protrusion 102b hits the tongue pieces 517a and 517b. Therefore, the battery holder 50 is not stored in the battery chamber 101.
That is, the battery holder 50 is not stored in the battery chamber 101 by mistake in the battery length direction of the battery holder 50.

尚、電池ホルダ本体５１の舌片５１７ａ，５１７ｂはいずれか片方のみであってもよい。
また、ガイド用突出部１０２ａ，１０２ｂはレール状に連続していなくてもよい。 In addition, only one of the tongue pieces 517a and 517b of the battery holder main body 51 may be used.
The guide protrusions 102a and 102b may not be continuous in a rail shape.

以上のとおり、電池ホルダ５０は、誤った向きで電池室１０１に収納されることはなく、常に正しい向きでのみ電池室１０１に収納されるので、電子機器１への逆電圧の印加を防止できる。
よって、本発明の電池収納部を備えた電子機器は、常に正しく電源供給されるとともに、電池交換を安全に行うことができる。 As described above, the battery holder 50 is not stored in the battery chamber 101 in the wrong direction, and is always stored in the battery chamber 101 only in the correct direction, so that application of a reverse voltage to the electronic device 1 can be prevented. .
Therefore, the electronic device including the battery storage unit of the present invention can always be correctly supplied with power and can be safely replaced.

次に、中間端子５２１，５２２の別の実施形態を説明する。
図９は中間端子５２１，５２２の第２の実施形態であり、中央部分にＵ字状部５２ｂを持たないので、第１の実施形態より容易に加工できる。 Next, another embodiment of the intermediate terminals 521 and 522 will be described.
FIG. 9 shows a second embodiment of the intermediate terminals 521 and 522. Since the center portion does not have the U-shaped portion 52b, it can be processed more easily than the first embodiment.

図１０は中間端子５２１，５２２の第３の実施形態であり、第２の実施形態よりさらに容易に加工可能な例である。
第３の実施形態は、電池ホルダ本体５１の係止穴５１４に圧入するなど、係止部５２ａのみで中間端子５２１，５２２を電池ホルダ本体５１へ固定できる場合に使用するものであり、先端のＬ字状に曲げてなるＬ字状部５２ｃが電池の電極と接する。 FIG. 10 shows a third embodiment of the intermediate terminals 521 and 522, which is an example that can be processed more easily than the second embodiment.
The third embodiment is used when the intermediate terminals 521 and 522 can be fixed to the battery holder main body 51 only by the locking portion 52a, such as press-fitting into the locking hole 514 of the battery holder main body 51. An L-shaped portion 52c bent into an L-shape is in contact with the battery electrode.

次に、電池ホルダ５０の別の実施形態を説明する。
上記実施形態の電池ホルダ５０は、４本の電池を電池の長さ方向に２本ずつ、基板５１１の上下の面に２列に並べて保持したが、別の実施形態として４本の電池を電池ホルダ本体５１の基板５１１の上面のみに、例えば電池の長さ方向に２本ずつ２列に並べて保持しても良い。
以下に電池ホルダ５０の別の実施形態について説明する。
電池ホルダ本体５１には、基板５１１の上面のみに保持ツメ５１３を形成し、各列の電池と電池の間に中間端子５２１，５２２のそれぞれを配置する。

After loading the battery between the terminals, the battery chamber may be covered with a battery cover.
Hereinafter, another embodiment of the battery chamber 101 will be described with reference to an example in which two batteries are housed in series.

電池室内のケースには、バネ性を有する一方の端子と他方の端子が電池室の長手方向の同一線上でバネ性を示すように対峙して配置され、電池室の長手方向のほぼ中間に係止穴が形成されている。
中間端子５２１は、係止部５２ａが係止穴に差込まれて、係止部５２ａを回動中心としてケースへ揺動可能に係止される。
次に、２本の電池は中間端子５２１を挟みながらバネ性を有する一方の端子と他方の端子の間に装填され、中間端子５２１を介した直列電池としてふるまい、その直列電池の両端はバネ性を有する端子で付勢される。
そして電池室は、電池蓋をケースに取付けることで蓋をされる。
以上のとおり、本実施形態は、電池ホルダ５０を用いずに電池を収納できるので、さらに省スペースなものにできる。 In the case inside the battery chamber, one terminal having the spring property and the other terminal are arranged to face each other so as to show the spring property on the same line in the longitudinal direction of the battery chamber, and are approximately in the middle of the battery chamber in the longitudinal direction. A blind hole is formed.
The intermediate terminal 521 is locked to the case so that the locking portion 52a is inserted into the locking hole and the locking portion 52a is the center of rotation.
Next, the two batteries are loaded between one terminal having spring property and the other terminal while sandwiching the intermediate terminal 521, and behave as a series battery via the intermediate terminal 521, and both ends of the series battery have spring properties. It is energized by a terminal having
The battery chamber is covered by attaching a battery cover to the case.
As described above, the present embodiment can store a battery without using the battery holder 50, and thus can further save space.

以上説明したとおり、本発明の電池収納部は、酸化皮膜によって生じる接触抵抗の増大を防止し、安定した電源供給を可能としながら、省スペースで電池交換容易なものにできる。
よって、本発明の電池収納部を備えた電子機器は、常に安定した動作を行うことができ、小型にできる。 As described above, the battery housing portion of the present invention can prevent an increase in contact resistance caused by an oxide film, and can make a stable power supply while saving space and allowing easy battery replacement.
Therefore, the electronic device provided with the battery housing portion of the present invention can always perform a stable operation and can be downsized.
