Description

本発明はボタン型電池内蔵機器に関し、特に、機器の動作電源からの充電を受け、機器の使用期間において交換の必要のないボタン型電池を内蔵し、機器を廃棄時する際にはそのボタン型電池を簡単に機器から取り出せるようにしたボタン型電池内蔵機器に関する。   The present invention relates to a button-type battery built-in device, and in particular, a button-type battery that is charged from an operating power supply of the device and does not need to be replaced during the use period of the device. The present invention relates to a button-type battery built-in device that allows a battery to be easily removed from the device.

例えばビデオカメラなどの機器には、この機器の動作電源となる電池の他にも、カレンダーや時計機能などのための各種データのバックアップ用にボタン型電池が備えられている。このバックアップ用のボタン型電池として一般に広く一次電池が用いられている。しかし、一次電池は例えば一年程で交換が必要であり、交換の度に時計などの再設定操作が必要となり面倒である。   For example, a device such as a video camera is provided with a button-type battery for backup of various data for a calendar function, a clock function, etc., in addition to a battery serving as an operation power source of the device. In general, a primary battery is widely used as a button type battery for backup. However, the primary battery needs to be replaced, for example, in about one year, and a resetting operation such as a clock is required every time it is replaced, which is troublesome.

このため、近年では、一次電池に代えて、機器の動作電源となる電池などからの充電を受け交換を不要とした二次電池がバックアップ用のボタン型電池として採用されるようになってきている。   For this reason, in recent years, secondary batteries that are charged from a battery or the like serving as an operating power source for equipment and that do not require replacement have been adopted as backup button-type batteries instead of primary batteries. .

ところで、ボタン型電池は、その廃棄に際しては環境保護あるいはリサイクルの観点から取り扱いに注意しなければならない。すなわち、機器から取り外して販売店や製造メーカーのサービスセンターなどのボタン型電池を回収してくれる所に持って行って適切に処置をしてもらう必要がある。   By the way, button batteries must be handled with care from the viewpoint of environmental protection or recycling. In other words, it is necessary to remove it from the device and take it to a place where the button-type battery is collected such as a store or a manufacturer's service center to have it properly treated.

しかし、二次電池は交換を不要としたために、機器に内蔵されている回路基板に直接はんだ付けで実装されて機器に組み込まれているので、機器を分解したり、一般家庭にはない特殊な工具（はんだごてなど）を必要としたり、使用者がボタン型電池を機器から取り外すのは困難である。   However, since the secondary battery does not need to be replaced, it is mounted on the circuit board built into the device by soldering directly into the device. It is difficult to require a tool (such as a soldering iron) or to remove the button-type battery from the device.

そこで、特許文献１には、ボタン型電池をフレキシブルケーブル及びコネクタを介して機器内の回路と接続させ、機器を廃棄する際には、機器から電池蓋を取り外してフレキシブルケーブルをコネクタから抜くことでボタン型電池を機器から容易に取り外せるようにしたことが開示されている。
特開平９−１６３１９９号公報 Therefore, in Patent Document 1, a button-type battery is connected to a circuit in a device via a flexible cable and a connector, and when the device is discarded, the battery cover is removed from the device and the flexible cable is removed from the connector. It is disclosed that the button-type battery can be easily detached from the device.
JP 9-163199 A

上記特許文献１では、フレキシブルケーブルにおいて、コネクタに差し込まれる端部の反対側の端部には、一対の弾性板からなる端子板が実装され、ボタン型電池はそれら端子板で挟み込まれてフレキシケーブルに保持されると共に電気的に接続されている。   In the above-mentioned patent document 1, in the flexible cable, a terminal plate made of a pair of elastic plates is mounted on the end opposite to the end inserted into the connector, and the button-type battery is sandwiched between the terminal plates, and the flexi cable And electrically connected.

このように端子板でボタン型電池を挟み込んだだけの保持構造では、特に小型のボタン型電池では安定して保持しにくいため、フレキシケーブルを引き抜く際に端子板からボタン型電池が外れ、機器の奥の方へと入り込んでしまい取り出せなくなるおそれがある。   In this way, with a holding structure in which the button battery is simply sandwiched between the terminal plates, it is difficult to hold the battery in a stable manner, especially with a small button battery. There is a risk of getting in the back and making it impossible to remove.

本発明は上述の問題に鑑みてなされ、その目的とするところは、ボタン型電池を機器の内部から簡単且つ確実に取り出すことのできるボタン型電池内蔵機器を提供することにある。   The present invention has been made in view of the above-described problems, and an object thereof is to provide a button-type battery built-in device that allows a button-type battery to be easily and reliably removed from the inside of the device.

以上の課題を解決するにあたり、本発明のボタン型電池内蔵機器では、可撓性配線部材の一端部は筐体内に内蔵された回路基板に実装されたコネクタに抜き差し自在に差し込まれ、他端部は可撓性配線部材と電気的に接続する配線が形成されたボタン型電池支持板に接続され、このボタン型電池支持板の一端部は筐体に開口されたボタン型電池取出口に臨んで位置され、ボタン型電池はボタン型電池支持板上に搭載されて筐体内に内蔵され、そのボタン型電池の電極は導電性の接合剤でボタン型電池支持板の配線に接合されていることを特徴としている。   In solving the above problems, in the button-type battery built-in device of the present invention, one end of the flexible wiring member is removably inserted into a connector mounted on a circuit board built in the housing, and the other end is inserted. Is connected to a button-type battery support plate on which wiring to be electrically connected to the flexible wiring member is formed, and one end of the button-type battery support plate faces a button-type battery outlet opening in the housing. The button-type battery is mounted on the button-type battery support plate and built in the housing, and the button-type battery electrode is bonded to the wiring of the button-type battery support plate with a conductive bonding agent. It is a feature.

ボタン型電池取出口に臨んで位置されているボタン型電池支持板の一端部を指などでつまんでボタン型電池取出口の外に引き出すと、ボタン型電池支持板に搭載されたボタン型電池もボタン型電池支持板と共にボタン型電池取出口の外に引き出される。ボタン型電池支持板に接続されている可撓性配線部材は筐体内部で折り畳まれるように収められているが、ボタン型電池支持板がボタン型電池取出口の外に引き出されることで、その引き出し方向に可撓性配線部材は引っ張られて伸ばされ、コネクタに差し込まれている一端部に引っ張り張力が作用してコネクタから抜ける。これにより、ボタン型電池は機器から分離されて、機器とは別に分けて処分することができる。   If you push one end of the button-type battery support plate located at the button-type battery outlet with your fingers and pull it out of the button-type battery outlet, the button-type battery mounted on the button-type battery support plate It is pulled out of the button type battery outlet together with the button type battery support plate. The flexible wiring member connected to the button-type battery support plate is housed so that it can be folded inside the housing, but when the button-type battery support plate is pulled out of the button-type battery outlet, The flexible wiring member is pulled and extended in the pull-out direction, and pulling tension acts on one end portion inserted into the connector so that the flexible wiring member is pulled out from the connector. Thereby, the button type battery is separated from the device and can be disposed separately from the device.

ボタン型電池はその電極が導電性の接合剤でボタン型電池支持板の配線に接合されることで、ボタン型電池支持板に固定され、且つ、ボタン型電池支持板の配線、可撓性配線部材及びコネクタを介して回路基板と電気的に接続される。このようなボタン型電池の保持構造は端子板で挟み込んだだけの保持構造に比べ、特に小型のボタン型電池であっても安定して保持することができ、ボタン型電池支持板及び可撓性配線部材を引き抜くときにボタン型電池がボタン型電池支持板から外れて機器の内部に入り込んでしまうのを防げる。   The button-type battery is fixed to the button-type battery support plate by bonding its electrode to the button-type battery support plate wiring with a conductive bonding agent, and the button-type battery support plate wiring, flexible wiring It is electrically connected to the circuit board via the member and the connector. Such a button-type battery holding structure can stably hold even a small button-type battery, compared to a holding structure simply sandwiched between terminal plates. When the wiring member is pulled out, the button-type battery can be prevented from coming off the button-type battery support plate and entering the inside of the device.

可撓性配線部材が可撓性を有していることによって、コネクタへの差込部分からボタン型電池取出口へと至る経路が曲がっている場合でも円滑にコネクタから引き抜くことができる。可撓性配線部材としては、フレキシブル配線板、フレキシブルケーブルなどが挙げられる。   Since the flexible wiring member has flexibility, it can be smoothly pulled out from the connector even when the path from the insertion portion to the connector to the button-type battery outlet is bent. Examples of the flexible wiring member include a flexible wiring board and a flexible cable.

ボタン型電池支持板は、可撓性を有していても構わないが、ボタン型電池の電極とボタン型電池支持板の配線との接合を安定して維持するためには可撓性を有していない方が好ましい。ここで、可撓性を有しないとは、完全な剛体である必要はなくボタン型電池に無理な応力を作用させるような撓みや曲げが生じない硬さや剛性を有していればよい。例えば、ガラス布などの補強材を樹脂に含浸させて得られる配線基板や、フレキシブル配線板の裏面に金属板あるいは硬さのある樹脂板を貼り付けた構成などが挙げられる。   The button type battery support plate may have flexibility, but in order to stably maintain the bonding between the button type battery electrode and the button type battery support plate wiring, the button type battery support plate has flexibility. It is preferable not to do so. Here, “not having flexibility” does not need to be a complete rigid body, and may have hardness or rigidity that does not cause bending or bending that causes excessive stress to be applied to the button-type battery. For example, a wiring board obtained by impregnating a reinforcing material such as a glass cloth with a resin, or a structure in which a metal plate or a hard resin plate is attached to the back surface of a flexible wiring board.

接合剤としては、はんだや、銀粉などの金属微粒子をペースト状の樹脂中に混合させた導電性接着剤などが挙げられる。   Examples of the bonding agent include solder and conductive adhesive obtained by mixing metal fine particles such as silver powder in a paste-like resin.

また、ボタン型電池取出口を剥離可能な接着シートで塞ぐと共に、この接着シートに、ボタン型電池取出口に臨んで位置されるボタン型電池支持板の一端部を接着させれば、接着シートによって取出口内への異物の入り込みを防げると共に、接着シートを剥がせばそのまま接着シートに貼り付けられてボタン型電池支持板も接着シートと共にボタン型電池取出口の外に引き上げることができ、ボタン型電池取出口が小さく指を入れてボタン型電池支持板の一端部をつまみ出すのが困難な場合でもボタン型電池支持板の取り出しを何ら道具を用いずに接着シートの剥離と合わせて簡単に行える。   In addition, the button-type battery outlet is closed with a peelable adhesive sheet, and one end of the button-type battery support plate positioned facing the button-type battery outlet is bonded to the adhesive sheet. In addition to preventing foreign matter from entering the outlet, if the adhesive sheet is peeled off, the button-type battery support plate can be lifted out of the button-type battery outlet together with the adhesive sheet. Even when the battery outlet is small and it is difficult to pinch out one end of the button type battery support plate, the button type battery support plate can be easily taken out together with the peeling of the adhesive sheet without using any tools.

本発明によれば、回路基板のコネクタに一端部が差し込まれた可撓性配線部材に接続されたボタン型電池支持板上にボタン型電池が搭載され、その電極は導電性の接合剤でボタン型電池支持板の配線に接合されているので、特に小型のボタン型電池であってもボタン型電池支持板に安定して保持することができ、ボタン型電池支持板を引っ張って可撓性配線部材をコネクタから抜く際に、ボタン型電池がボタン型電池支持板から外れてしまうことを防げる。これにより、特別な工具や技能を要せずとも、ボタン型電池をボタン型電池支持板と共に確実に筐体内部から取り出すことができ、ボタン型電池の回収効率の向上が図れる。   According to the present invention, the button-type battery is mounted on the button-type battery support plate connected to the flexible wiring member having one end inserted into the connector of the circuit board, and the electrode is formed of the conductive bonding agent and the button. Since it is joined to the wiring of the battery-type battery support plate, even a small button-type battery can be stably held on the button-type battery support plate. When the member is removed from the connector, the button-type battery can be prevented from being detached from the button-type battery support plate. Accordingly, the button type battery can be reliably taken out from the inside of the casing together with the button type battery support plate without requiring a special tool or skill, and the recovery efficiency of the button type battery can be improved.

（ボタン型電池内蔵機器の構成）
図８は本実施形態に係るボタン型電池内蔵機器１の概略図を示す。本実施形態では、ボタン型電池内蔵機器１の一例としてビデオカメラを示す。 [First Embodiment]
(Configuration of button-type battery built-in device)
FIG. 8 is a schematic diagram of the button-type battery built-in device 1 according to the present embodiment. In this embodiment, a video camera is shown as an example of the button-type battery built-in device 1.

ボタン型電池内蔵機器（以下、単に機器とも呼ぶ）１は、主として、本体部２と光学レンズ３と液晶表示部（本体部２の図示されている一方の側面４の反対側面に取り付けられる）から構成される。また、本体部２の一方の側面４には、ボタン型電池取出口（以下、単に取出口とも呼ぶ）５が形成されている。この取出口５の内方に後述するボタン型電池が内蔵されている。   A button-type battery built-in device (hereinafter also simply referred to as a device) 1 mainly includes a main body 2, an optical lens 3, and a liquid crystal display (attached to the side of the main body 2 opposite to the side 4 shown in the figure). Composed. A button-type battery outlet (hereinafter also simply referred to as an outlet) 5 is formed on one side surface 4 of the main body 2. A button-type battery described later is built in the outlet 5.

図１は本体部２の内部を示す。本体部２の筐体６の中には複数（図示では２個）の回路基板７ａ、７ｂが収められ、筐体６に対してビス止めなどで固定される。回路基板７ａ、７ｂは、搭載される部品の重さに耐え、筐体６に固定できる硬さと強度を持ったリジッドなプリント配線基板上に電子部品８やコネクタ９などの各種部品が実装されてなる。互いの回路基板７ａ、７ｂ間は、図示しないケーブルあるいはフレキシブル配線板で電気的に接続されている。   FIG. 1 shows the inside of the main body 2. A plurality (two in the figure) of circuit boards 7a and 7b are housed in the housing 6 of the main body 2 and fixed to the housing 6 with screws or the like. The circuit boards 7a and 7b are mounted with various parts such as an electronic part 8 and a connector 9 on a rigid printed wiring board that can withstand the weight of the parts to be mounted and can be fixed to the housing 6. Become. The circuit boards 7a and 7b are electrically connected by a cable or a flexible wiring board (not shown).

図７はコネクタ９の断面図を示す。コネクタ９は、後述する可撓性配線部材のエッジ端子の抜き差しを容易に行える例えばLIF（Low Insertion Force）タイプまたはNON-ZIF（Zero Insertion Force）タイプのコネクタである。   FIG. 7 shows a cross-sectional view of the connector 9. The connector 9 is, for example, a LIF (Low Insertion Force) type or a NON-ZIF (Zero Insertion Force) type connector that can easily insert and remove an edge terminal of a flexible wiring member to be described later.

コネクタ９は、取出口５に近い側に配設された回路基板７ａに実装されている。さらに具体的には、その回路基板７ａにおいて、取出口５の下方に位置する縁部に実装され、差込口１０を回路基板７ａの面に対して水平に（横向きに）且つ回路基板７ａの外側へと向けている。差込口１０には後述する可撓性配線基板のエッジ端子が差し込まれ、そのエッジ端子は差込口１０内の端子１１に圧接する。コネクタ９の端子１１の後端部は回路基板７ａ上に形成された配線にはんだ付けされている。   The connector 9 is mounted on a circuit board 7 a disposed on the side close to the outlet 5. More specifically, the circuit board 7a is mounted on an edge located below the outlet 5, and the insertion port 10 is horizontally (sideways) with respect to the surface of the circuit board 7a and the circuit board 7a. It faces outward. An edge terminal of a flexible wiring board, which will be described later, is inserted into the insertion port 10, and the edge terminal is in pressure contact with the terminal 11 in the insertion port 10. The rear end portion of the terminal 11 of the connector 9 is soldered to the wiring formed on the circuit board 7a.

図４は可撓性配線部材１２及びボタン型電池支持板（以下、単に支持板とも呼ぶ）１３の平面図を示す。   FIG. 4 is a plan view of the flexible wiring member 12 and the button type battery support plate (hereinafter also simply referred to as a support plate) 13.

可撓性配線部材１２は、例えばポリイミド、ポリエステルなどの可撓性がある絶縁フィルム上に銅箔などの金属箔で導体パターンを形成してなる。可撓性配線部材１２の一端部の表面には端子１５が露出して形成され、裏面には樹脂製（あるいは金属製でもよい）の補強板が貼り付けられ、上記コネクタ９への抜き差しに際して撓んだり折れ曲がったりすることのないようされた硬さと強度を持ったエッジ端子１４として構成されている。   The flexible wiring member 12 is formed by forming a conductor pattern with a metal foil such as a copper foil on a flexible insulating film such as polyimide or polyester. A terminal 15 is exposed on the surface of one end of the flexible wiring member 12, and a resin (or metal) reinforcing plate is affixed to the back surface. It is configured as an edge terminal 14 having hardness and strength that is prevented from being bent or bent.

可撓性配線部材１２の他端部は支持板１３に接続されている。例えば、支持板１３はガラス布などの補強材に樹脂を含浸させて得られるリジッドなプリント配線板であり、この支持板１３の内層に可撓性配線部材１２の他端部を挟んだ構造となっている。あるいは、可撓性配線板１２と支持板１３とを一体的なフレキシブル配線板として、支持板１３に相当する部分の裏面に樹脂製あるいは金属製の補強板を貼り付けた構造としてもよい。   The other end of the flexible wiring member 12 is connected to the support plate 13. For example, the support plate 13 is a rigid printed wiring board obtained by impregnating a reinforcing material such as glass cloth with a resin, and has a structure in which the other end portion of the flexible wiring member 12 is sandwiched between inner layers of the support plate 13. It has become. Alternatively, the flexible wiring board 12 and the support plate 13 may be integrated into a flexible wiring board, and a resin or metal reinforcing plate may be attached to the back surface of the portion corresponding to the support plate 13.

支持板１３の一端部（可撓性配線部材１２と接続された端部の反対側の端部）１６は、支持板１３の他の部分より幅広とされ、その一端部１６と他の部分との間に段が形成されている。   One end of the support plate 13 (the end opposite to the end connected to the flexible wiring member 12) 16 is wider than the other part of the support plate 13. A step is formed between the two.

支持板１３の一端部１６寄りの部分には、支持板１３の表面に露出してランド１７が形成され、そのランド１７は支持板１３上に形成された配線（図示せず）を通じて可撓性配線部材１２に形成された配線（図示せず）に接続され、この可撓性配線部材１２の配線はエッジ端子１４の端子１５に接続されている。したがって、支持板１３のランド１７とエッジ端子１４の端子１５とは電気的に接続されている。ランド１７と端子１５間を接続する配線は絶縁性のカバーフィルムで覆われて外部に露出していない。   A land 17 is formed on the surface of the support plate 13 near the one end 16 so as to be exposed on the surface of the support plate 13, and the land 17 is flexible through wiring (not shown) formed on the support plate 13. The wiring member 12 is connected to a wiring (not shown) formed on the wiring member 12, and the wiring of the flexible wiring member 12 is connected to the terminal 15 of the edge terminal 14. Therefore, the land 17 of the support plate 13 and the terminal 15 of the edge terminal 14 are electrically connected. The wiring connecting the land 17 and the terminal 15 is covered with an insulating cover film and is not exposed to the outside.

図５は支持板１３上にボタン型電池１８が搭載された状態を示す。ボタン型電池１８の電極１８ａはランド１７上に位置決めされ、ランド１７と電極１８ａとは例えばはんだにて金属接合されて電気的に接続される。ボタン型電池１８の円形状の本体１８ｂの裏面は絶縁性の両面接着テープあるいはボンディングペーストにて支持板１３上に固定される。   FIG. 5 shows a state where the button-type battery 18 is mounted on the support plate 13. The electrode 18a of the button-type battery 18 is positioned on the land 17, and the land 17 and the electrode 18a are electrically connected by, for example, metal bonding with solder. The back surface of the circular body 18b of the button-type battery 18 is fixed on the support plate 13 with an insulating double-sided adhesive tape or bonding paste.

以上のように構成されるボタン型電池１８は上記支持板１３に搭載された状態で、支持板１３及び可撓性配線部材１２と共に、図１、図３に示すようにして筐体６内に内蔵される。   The button type battery 18 configured as described above is mounted on the support plate 13 together with the support plate 13 and the flexible wiring member 12 in the housing 6 as shown in FIGS. Built in.

コネクタ９の差込口１０には可撓性配線部材１２のエッジ端子１４が差し込まれてエッジ端子１４は差込口１０内の相対向する端子１１間に狭圧される。可撓性配線部材１２は、エッジ端子１４とコネクタ９との接続部を起点に下方へと垂下され、可撓性配線部材１２に接続されている支持板１３は上方の取出口５側へと折り返される。   The edge terminal 14 of the flexible wiring member 12 is inserted into the insertion port 10 of the connector 9, and the edge terminal 14 is narrowed between the terminals 11 facing each other in the insertion port 10. The flexible wiring member 12 hangs downward from the connection portion between the edge terminal 14 and the connector 9, and the support plate 13 connected to the flexible wiring member 12 moves toward the upper outlet 5 side. Wrapped.

支持板１３の一端部１６は取出口５の位置まで引き上げられ、図６に示すように、その両端部１６ａが取出口５につながって形成された凹所１９に嵌まり込む。これにより、支持板１３の一端部１６は凹所１９に支えられて筐体６内部への落下止めがなされ、図１、６に示す、取出口５に臨む位置でもって保持される。   One end 16 of the support plate 13 is pulled up to the position of the take-out port 5, and as shown in FIG. 6, the both end portions 16 a are fitted into a recess 19 formed to connect to the take-out port 5. As a result, the one end 16 of the support plate 13 is supported by the recess 19 and is prevented from falling into the housing 6 and is held at the position facing the outlet 5 shown in FIGS.

以上のようにして、可撓性配線部材１２のエッジ端子１４はコネクタ９に差し込まれ、支持板１３の一端部１６は取出口５に臨む位置で保持され、可撓性配線部材１２と支持板１３との境界付近はＵ字を形成するようにして湾曲した状態で可撓性配線部材１２及びこれと一体的に接続する支持板１３は筐体６内に内蔵される。   As described above, the edge terminal 14 of the flexible wiring member 12 is inserted into the connector 9, and the one end portion 16 of the support plate 13 is held at a position facing the outlet 5. The flexible wiring member 12 and the support plate 13 connected integrally therewith are built in the housing 6 in a curved state so as to form a U-shape near the boundary with the housing 13.

支持板１３の表面に搭載されたボタン型電池１８は、相対向する支持板１３の表面と、可撓性配線部材１２の表面との間に位置される。ボタン型電池１８はその円形状の本体１８ｂの表面が可撓性配線部材１２の表面に対向する縦にされた姿勢となっている。   The button-type battery 18 mounted on the surface of the support plate 13 is positioned between the surface of the support plate 13 and the surface of the flexible wiring member 12 facing each other. The button-type battery 18 has a vertical posture in which the surface of the circular main body 18 b faces the surface of the flexible wiring member 12.

図３に示すように、回路基板７ａ、７ｂにおいてコネクタ９の差込口１０の前方（図において左方）部分は切り欠かれており、この切欠き２０ａ、２０ｂによって形成される空間に、可撓性配線部材１２、支持板１３及びボタン型電池１８が位置される。これによって、筐体内部の限られたスペースを有効に利用することができる。   As shown in FIG. 3, the front (left side in the drawing) portion of the insertion port 10 of the connector 9 is cut out in the circuit boards 7a and 7b, and the space formed by the cutouts 20a and 20b is possible. The flexible wiring member 12, the support plate 13, and the button type battery 18 are positioned. Thereby, the limited space inside the housing can be used effectively.

また、エッジ端子１４から支持板１３の一端部１６にかけて可撓性配線部材１２及び支持板１３はねじられておらず、図１に示すように、コネクタ９の差込口１０は、ボタン型電池１８の搭載された支持板１３の表面に対向している。更に、コネクタ９とエッジ端子１４との接続部は取出口５の下方に位置している。これらのことによって、後述するように、支持板１３の一端部１６を取出口５の上方へと引き上げることによって、支持板１３、ボタン型電池１８及び可撓性配線部材１２に無理な力をかけることなく簡単にコネクタ９の差込口１０からエッジ端子１４を抜くことができる。   Further, the flexible wiring member 12 and the support plate 13 are not twisted from the edge terminal 14 to the one end portion 16 of the support plate 13, and as shown in FIG. It faces the surface of the support plate 13 on which 18 is mounted. Furthermore, the connection part between the connector 9 and the edge terminal 14 is located below the outlet 5. As described later, by pushing up the one end 16 of the support plate 13 above the outlet 5, an excessive force is applied to the support plate 13, the button-type battery 18, and the flexible wiring member 12. The edge terminal 14 can be easily removed from the insertion port 10 of the connector 9 without any problem.

図８に示すように、ボタン電池内蔵機器１の一方の側面４には、凹部４ａが形成され、取出口５はその凹部４ａの底面に開口して形成されている。凹部４ａには、電源電池２１が嵌め込まれて取出口５は塞がれる。更に、電源電池２１を覆うようにしてカバー２２が取り付けられる。   As shown in FIG. 8, a concave portion 4a is formed on one side surface 4 of the button cell built-in device 1, and an outlet 5 is formed in the bottom surface of the concave portion 4a. The power supply battery 21 is fitted in the recess 4a, and the outlet 5 is closed. Further, a cover 22 is attached so as to cover the power battery 21.

電源電池２１は、この機器１の動作電源として機能する。ボタン型電池１８は、この機器１が電源電池２１からの電源の供給を受けない状態（電源スイッチをオフにしたり、電源電池２１が切れたりしたときなど）であっても、日付や時刻、その他設定したあるいは記録された各種データを保持するバックアップ用の電池として機能する。更に、ボタン型電池１８は電源電池２１から充電を受けることによって、機器１の使用期間中における交換が不要となる。   The power battery 21 functions as an operating power source for the device 1. The button-type battery 18 can be used for the date, time, etc. even when the device 1 is not supplied with power from the power battery 21 (when the power switch is turned off or the power battery 21 is exhausted). It functions as a backup battery that holds various data set or recorded. Furthermore, the button-type battery 18 is charged from the power supply battery 21, so that it is not necessary to replace the device 1 during the period of use.

ボタン型電池１８からの電力は、支持板１３、可撓性配線部材１２及びコネクタ９を介して回路基板１７ａ、１７ｂに供給される。充電時には、ボタン型電池１８は、回路基板１７ａ、１７ｂ、コネクタ９、可撓性配線部材１２及び支持板１３を介して電源電池２１からの電力を受ける。   Electric power from the button-type battery 18 is supplied to the circuit boards 17a and 17b via the support plate 13, the flexible wiring member 12, and the connector 9. During charging, the button-type battery 18 receives power from the power supply battery 21 via the circuit boards 17 a and 17 b, the connector 9, the flexible wiring member 12, and the support plate 13.

（ボタン型電池の取り出し方）
機器１を廃棄する際には、以下の手順にて機器１からボタン型電池１８を取り出す。 (How to remove the button battery)
When the device 1 is discarded, the button-type battery 18 is taken out from the device 1 according to the following procedure.

先ず、図８に示すカバー２２を取り外す。具体的には、ロック解除レバー２３を押すあるいはスライドさせるなどして、カバー２２に係合していたロック部材（図示省略）をカバー２２との係合解除位置に動作させる。これにより、ドライバーなどの工具を使わずともカバー２２を簡単に取り外すことができる。   First, the cover 22 shown in FIG. 8 is removed. Specifically, the lock release lever 23 is pushed or slid to move the lock member (not shown) engaged with the cover 22 to the engagement release position with the cover 22. Thereby, the cover 22 can be easily removed without using a tool such as a screwdriver.

カバー２２が取り外されると、次は電源電池２１を取り外す。電源電池２１は凹部４ａに嵌まっているだけであるので手で簡単に取り外すことができる。電源電池２１が取り外されることで、取出口５が露出する。   When the cover 22 is removed, the power battery 21 is removed next. Since the power battery 21 only fits into the recess 4a, it can be easily removed by hand. The outlet 5 is exposed by removing the power battery 21.

そして、図６に示すように、取出口５内の凹所１９に支持され取出口５に露出している支持板１３の一端部１６を指で（あるいはペン先やつま楊枝などの先の細いもので）つまみ出し引き上げる。   Then, as shown in FIG. 6, one end 16 of the support plate 13 supported by the recess 19 in the outlet 5 and exposed to the outlet 5 is fingered (or a pointed object such as a pen tip or a toothpick). ) Pull out the knob.

取出口５はボタン型電池１８の厚さよりも広い開口面積を有し、したがって、支持板１３の一端部１６を引き上げることによって、縦にされたボタン型電池１８を取出口５の外に引き出すことができる。   The outlet 5 has an opening area wider than the thickness of the button-type battery 18, and therefore the button-type battery 18 that is made vertical is pulled out of the outlet 5 by pulling up one end 16 of the support plate 13. Can do.

支持板１３の一端部１６の引き上げを続けていくと、図２に示すように、支持板１３、ボタン型電池１８、及び可撓性配線部材１２の大部分が取出口５の外に出される。更に引き上げることでその引き上げ方向にエッジ端子１４が引っ張られて、エッジ端子１４がコネクタ９から抜ける。   When the pulling-up of the one end portion 16 of the support plate 13 is continued, most of the support plate 13, the button type battery 18, and the flexible wiring member 12 are taken out of the outlet 5 as shown in FIG. 2. . By further pulling up, the edge terminal 14 is pulled in the pulling direction, and the edge terminal 14 comes out of the connector 9.

コネクタ９の端子保持力は人が簡単に引っ張って抜くことの力（例えば０．７Ｎ）であり、したがって、０．７Ｎ以上の力でエッジ端子１４が引っ張られればコネクタ９から抜ける。支持板１３を取出口５の真上方向にそのまま引っ張ってもエッジ端子１４をコネクタから抜くことはできるが、支持板１３と可撓性配線板１２とを一直線状にすることのできる斜め方向に傾けながら引っ張ればさらに抜け易くできる。   The terminal holding force of the connector 9 is a force (for example, 0.7 N) that a person can easily pull and pull out. Therefore, if the edge terminal 14 is pulled with a force of 0.7 N or more, the terminal 9 comes out of the connector 9. The edge terminal 14 can be removed from the connector even if the support plate 13 is pulled directly above the outlet 5, but the support plate 13 and the flexible wiring board 12 can be aligned in an oblique direction. Pulling while tilting makes it easier to pull out.

以上述べたように、工具を用いることなく且つ特別な技能を必要とせずにボタン型電池１８を機器１から取り外すことができ、ボタン型電池１８が機器１に内蔵されたまま廃棄されることによるボタン型電池１８を原因とする環境汚染を防げ、またボタン型電池１８のリサイクルも行える。   As described above, the button-type battery 18 can be removed from the device 1 without using a tool and without requiring any special skill, and the button-type battery 18 is disposed while it is built in the device 1. Environmental pollution caused by the button-type battery 18 can be prevented, and the button-type battery 18 can be recycled.

そして、本実施形態では、ボタン型電池１８はその電極１８ａを支持板１３のランド１７にはんだ付けされることで接合され、且つボタン型電池１８の本体１８ｂは両面接着テープなどで支持板１３に接着されている。このようにボタン型電池１８は支持板１３に対してしっかりと固定されているので、支持板１３を引き上げる際にボタン型電池１８が支持板１３から外れてしまうことがなく、確実にボタン型電池１８を筐体６の外に取り出せる。特に、上記特許文献１に示される端子板による挟み込みでは不安定な保持となってしまうような小型の（例えばコインよりも小さな）ボタン型電池であっても安定して支持板１３に保持することができる。   In this embodiment, the button-type battery 18 is joined by soldering the electrode 18a to the land 17 of the support plate 13, and the body 18b of the button-type battery 18 is attached to the support plate 13 with a double-sided adhesive tape or the like. It is glued. Since the button type battery 18 is firmly fixed to the support plate 13 in this way, the button type battery 18 is not detached from the support plate 13 when the support plate 13 is pulled up. 18 can be taken out of the housing 6. In particular, even a small button-type battery (for example, smaller than a coin) that is unstable when held by the terminal plate shown in Patent Document 1 is stably held on the support plate 13. Can do.

また、本実施形態では、支持板１３の裏面に補強板を貼り付けて支持板１３に撓みや曲げが生じないように硬さや剛性をもたせているので、支持板１３の撓みや曲げに起因するはんだ接合部の破損やボタン型電池１８の支持板１３からの剥離を確実に防ぐことができる。   Further, in the present embodiment, a reinforcing plate is attached to the back surface of the support plate 13 so that the support plate 13 has hardness and rigidity so that the support plate 13 does not bend or bend. Therefore, the support plate 13 is bent or bent. Breakage of the solder joint and separation of the button-type battery 18 from the support plate 13 can be reliably prevented.

更に、本実施形態では、ボタン型電池１８の支持板１３に対する保持及び電気的接触のために上記特許文献１のように端子板を用いないので、その端子板がない分、機器１内への内蔵のためのスペースを小さくでき、機器１の小型化の妨げにならない。   Furthermore, in this embodiment, since the terminal plate is not used as in Patent Document 1 for holding and electrical contact of the button-type battery 18 with respect to the support plate 13, the terminal plate is not included in the device 1. The space for incorporation can be reduced and does not hinder downsizing of the device 1.

［第２の実施形態］
次に本発明の第２の実施形態について説明する。なお、上記第１の実施形態と同じ構成部分には同一の符号を付しその詳細な説明は省略する。 [Second Embodiment]

図９は本実施形態に係るボタン型電池内蔵機器３０の本体部２の内部を示す。本実施形態が上記第１の実施形態と異なるのは、取出口５が接着シート２５で塞がれ、この接着シート２５の接着面に支持板１３の一端部１６が接着されている点である。   FIG. 9 shows the inside of the main body 2 of the button-type battery built-in device 30 according to the present embodiment. The present embodiment is different from the first embodiment in that the outlet 5 is closed with an adhesive sheet 25, and one end 16 of the support plate 13 is bonded to the adhesive surface of the adhesive sheet 25. .

機器３０の側面４には上記第１の実施形態と同様、電源電池２１が収められる凹部４ａが形成されているが、本実施形態ではその凹部４ａにおいて取出口５の周囲部分に接着シート貼付面２４が凹部４ａの底面よりわずかにくぼんだ面として形成されている。   Similar to the first embodiment, the side surface 4 of the device 30 is formed with a recess 4a in which the power supply battery 21 is accommodated. In this embodiment, the adhesive sheet sticking surface is provided around the outlet 5 in the recess 4a. 24 is formed as a surface slightly recessed from the bottom surface of the recess 4a.

そして、取出口５を塞ぐようにして、例えばポリエチレンからなる接着シート２５が接着シート貼付面２４に貼り付けられる。接着シート２５の表面は凹部４ａの底面とほぼ面一とされる。   Then, an adhesive sheet 25 made of, for example, polyethylene is attached to the adhesive sheet attaching surface 24 so as to close the outlet 5. The surface of the adhesive sheet 25 is substantially flush with the bottom surface of the recess 4a.

また、取出口５に臨む位置に保持されている支持板１３の一端部１６の上面は接着シート２５の接着面に接着されている。   Further, the upper surface of the one end portion 16 of the support plate 13 held at the position facing the outlet 5 is adhered to the adhesive surface of the adhesive sheet 25.

When the cover 22 is removed, the power battery 21 is removed next. The adhesive sheet 25 is exposed by removing the power battery 21.

そして、接着シート２５を剥がすと、取出口５が露出されると共に、接着シート２５にその一端部１６が接着されている支持板１３が接着シート２５と共に取出口５から引き出される。そして、図１０に示すように、支持板１３、ボタン型電池１８、及び可撓性配線部材１２が取出口５の外に引き出され、その引き上げ方向にエッジ端子１４が引っ張られて、エッジ端子１４がコネクタ９から抜ける。   When the adhesive sheet 25 is peeled off, the outlet 5 is exposed and the support plate 13 having one end 16 bonded to the adhesive sheet 25 is pulled out from the outlet 5 together with the adhesive sheet 25. Then, as shown in FIG. 10, the support plate 13, the button-type battery 18, and the flexible wiring member 12 are pulled out of the outlet 5, and the edge terminal 14 is pulled in the pulling direction, so that the edge terminal 14 Comes out of the connector 9.

このように本実施形態によれば、取出口５を塞ぐ接着シート２５を剥がすだけで、工具を用いることなく且つ特別な技能を必要とせずに簡単にボタン型電池１８を機器３０から取り外すことができる。特に、取出口５が小さくて指を入れて支持板１３の一端部１６をつまみ出すのが困難な場合に有効となる。   As described above, according to the present embodiment, the button-type battery 18 can be easily detached from the device 30 without using a tool and without requiring special skills, by simply peeling off the adhesive sheet 25 that closes the outlet 5. it can. This is particularly effective when the outlet 5 is small and it is difficult to put out a finger and pinch the one end 16 of the support plate 13.

なお、支持板１３の一端部１６を接着シート２５に接着させなくても、接着シート２５で取出口５を塞ぐだけでも、消耗した電源電池２１を充電するために凹部４ａから取り外したり、あるいは充電が完了した電源電池２１を凹部４ａにセットしたりする作業時に、取出口５からほこりや水分などの異物が入ってしまうことを防げる。   Even if the one end portion 16 of the support plate 13 is not adhered to the adhesive sheet 25, or just by closing the outlet 5 with the adhesive sheet 25, it can be removed from the recess 4 a or charged to charge the consumed power battery 21. It is possible to prevent foreign matter such as dust and moisture from entering from the outlet 5 during the operation of setting the power supply battery 21 that has been completed in the recess 4a.
