Description

電子部品内蔵カード、アッセンブリElectronic component built-in card, assembly
　本発明は、ドームスイッチを内蔵した電子部品内蔵カード、アッセンブリに関する。 The present invention relates to an electronic component built-in card and assembly including a dome switch.
　従来、スイッチ部、表示部を備え、ワンタイムパスワードを表示したり、ＩＣチップに記録された内容を確認できるＩＣカードがあった（例えば、特許文献１）。このタイプのＩＣカードは、電気基板上のスイッチ部と、カード面のカバー材である樹脂フィルム層との間に粘着剤層が形成され、粘着剤層がスイッチ部に粘着している。
　このため、従来のＩＣカードは、カード面から押下してスイッチ部を操作する場合に、良好なクリック感を得られなかった。 Conventionally, there has been an IC card that includes a switch unit and a display unit and can display a one-time password or confirm contents recorded on an IC chip (for example, Patent Document 1). In this type of IC card, an adhesive layer is formed between a switch portion on an electric board and a resin film layer that is a cover material for the card surface, and the adhesive layer adheres to the switch portion.
For this reason, the conventional IC card cannot obtain a good click feeling when it is pressed from the card surface to operate the switch unit.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings and the like.
In the embodiment, a view in which the normal direction of the display surface of the display unit 12 is the vertical direction Z and the electronic module 10 is viewed is referred to as a plan view. In the plan view, the horizontal direction when viewing the electronic module 10 or the like so that the display on the display unit 12 is in the normal position is referred to as X, and the vertical direction is referred to as Y. The shape in the plan view is appropriately referred to as a planar shape. In each drawing, the size and the like of the configuration in the vertical direction Z (thickness direction) and the like are appropriately exaggerated for clarity.
First, the electronic module 10 built in the card 20 will be described.
FIG. 1 is a plan view, a side view, and an external view of a card 20 of the electronic module 10 of the first embodiment.
FIG. 1A1 is a plan view of the electronic module 10.
1A2 is a cross-sectional view of the electronic module 10 (a2-a2 cross-sectional view of FIG. 1A1).
FIG. 1 (B1) is a plan view showing the internal configuration of the card 20. FIG.
FIG. 1B2 is a cross-sectional view of the card 20 (a cross-sectional view of the b2-b2 portion of FIG. 1B1).
　電子モジュール１０は、カード２０（電子部品内蔵カード）の使用毎に認証パスワード（いわゆるワンタイムパスワード）を生成する機能を有する。なお、電子モジュール１０は、接触用端子、ループアンテナ等を設けて、外部機器（例えば、カードリーダ）との間で通信できるようにしてもよい。
　電子モジュール１０は、電気基板１１、表示部１２、ボタン部３０、電池１４、ＩＣチップ１５を備える。
　電気基板１１は、リジッド又はフレキシブルタイプのプリント配線基板である。本実施形態では、電気基板１１は、ポリイミドから形成されるフレキシブルタイプである。電気基板１１の厚みは、例えば厚さ１００μｍ程度である。電気基板１１には、表示部１２、ボタン部３０が実装され、また、電池１４が接続端子１４ａによって接続及び固定されている。 The electronic module 10 has a function of generating an authentication password (so-called one-time password) every time the card 20 (electronic component built-in card) is used. The electronic module 10 may be provided with a contact terminal, a loop antenna, and the like so as to be able to communicate with an external device (for example, a card reader).
The electronic module 10 includes an electric substrate 11, a display unit 12, a button unit 30, a battery 14, and an IC chip 15.
The electric board 11 is a rigid or flexible type printed wiring board. In this embodiment, the electric substrate 11 is a flexible type formed from polyimide. The thickness of the electric substrate 11 is, for example, about 100 μm. The display unit 12 and the button unit 30 are mounted on the electric board 11, and the battery 14 is connected and fixed by a connection terminal 14a.
　表示部１２は、認証パスワードを表示する表示装置である。表示部１２は、例えば、液晶ディスプレイ、電子ペーパディスプレイ等である。
　ボタン部３０は、認証パスワードを生成する場合に、利用者が操作する押しボタンである。ボタン部３０は、操作情報をＩＣチップ１５に出力する。ボタン部３０の詳細は、後述する。 The display unit 12 is a display device that displays an authentication password. The display unit 12 is, for example, a liquid crystal display, an electronic paper display, or the like.
The button unit 30 is a push button operated by the user when generating an authentication password. The button unit 30 outputs operation information to the IC chip 15. Details of the button unit 30 will be described later.
　電池１４は、電子モジュール１０の表示部１２、ＩＣチップ１５等に電力を供給する部材である。
　ＩＣチップ１５は、電子モジュール１０を制御する制御装置である。ＩＣチップ１５は、電池１４から電力を供給されて駆動する。ＩＣチップ１５は、電子モジュール１０の処理を制御する制御プログラム等を記憶した記憶装置（図示せず）を備える。
　利用者によってボタン部３０が操作されると、ＩＣチップ１５は、ボタン部３０の出力に基づいて、認証パスワードを生成する。ＩＣチップ１５は、表示部１２を駆動して、この認証パスワードを表示する。 The battery 14 is a member that supplies power to the display unit 12 and the IC chip 15 of the electronic module 10.
The IC chip 15 is a control device that controls the electronic module 10. The IC chip 15 is driven by power supplied from the battery 14. The IC chip 15 includes a storage device (not shown) that stores a control program for controlling processing of the electronic module 10.
When the button unit 30 is operated by the user, the IC chip 15 generates an authentication password based on the output of the button unit 30. The IC chip 15 drives the display unit 12 to display this authentication password.
　図１（Ｂ）に示すように、カード２０は、電子モジュール１０の認証パスワードを利用した認証式のカードであり、例えば、銀行のキャッシュカード、クレジットカード等である。
　カード２０は、上シート２１（上層）、下シート２２（下層）、中基材２３、接着層２４、前述した電子モジュール１０を備える。 As shown in FIG. 1B, the card 20 is an authentication type card using the authentication password of the electronic module 10, and is, for example, a bank cash card or a credit card.
The card 20 includes an upper sheet 21 (upper layer), a lower sheet 22 (lower layer), a middle substrate 23, an adhesive layer 24, and the electronic module 10 described above.
　上シート２１は、電気基板１１よりも上側Ｚ２に積層され、カード２０の最上面に配置される樹脂シートである。上シート２１の厚さは、例えば１００～２００μｍ程度である。 The upper sheet 21 is a resin sheet that is laminated on the upper side Z <b> 2 from the electric substrate 11 and is disposed on the uppermost surface of the card 20. The thickness of the upper sheet 21 is, for example, about 100 to 200 μm.
　上シート２１は、透明な材料により形成されている。上シート２１には、窓部２１ａ、印刷層２１ｂが設けられている。
　窓部２１ａは、印刷層２１ｂが設けられていない領域である。窓部２１ａは、表示部１２に対応する位置に設けられている。このため、利用者は、窓部２１ａを通して、表示部１２の表示内容を視認できる。
　一方、印刷層２１ｂが設けられている領域では、印刷層２１ｂによりカード２０内部が隠蔽される。これにより、電子モジュール１０等の構造が、外部から視認できないようになっている。 The upper sheet 21 is made of a transparent material. The upper sheet 21 is provided with a window portion 21a and a printing layer 21b.
The window portion 21a is a region where the print layer 21b is not provided. The window 21 a is provided at a position corresponding to the display unit 12. For this reason, the user can visually recognize the display content of the display part 12 through the window part 21a.
On the other hand, in the area where the printing layer 21b is provided, the inside of the card 20 is concealed by the printing layer 21b. As a result, the structure of the electronic module 10 or the like cannot be viewed from the outside.
　下シート２２は、電気基板１１よりも下側Ｚ１に積層され、カード２０の最下面に配置される樹脂シートである。下シート２２の厚さは、例えば１００～２００μｍ程度である。なお、下シート２２は、内部の電子モジュール１０を視認できないように、隠蔽可能な色彩を有する材料から形成されるか、又は上シート２１と同様に、透明な材料により形成され、下面に印刷層が設けられる。 The lower sheet 22 is a resin sheet that is laminated on the lower side Z <b> 1 than the electric substrate 11 and is disposed on the lowermost surface of the card 20. The thickness of the lower sheet 22 is, for example, about 100 to 200 μm. The lower sheet 22 is formed of a material having a color that can be concealed so that the internal electronic module 10 cannot be visually recognized, or is formed of a transparent material like the upper sheet 21 and has a printed layer on the lower surface. Is provided.
　中基材２３は、上シート２１及び下シート２２に挟まれるように配置されている。中基材２３は、例えば、塩化ビニルやＰＥＴ、ＰＥＴ－Ｇなどのポリエステルの樹脂シートである。中基材２３の厚さは、例えば４００～６００μｍ程度である。中基材２３の枠内部は、電子モジュール１０を配置する開口孔になっている。電子モジュール１０は、数枚のテープ１１ｂを用いて中基材２３に仮固定される。 The middle substrate 23 is disposed so as to be sandwiched between the upper sheet 21 and the lower sheet 22. The middle base material 23 is, for example, a resin sheet of polyester such as vinyl chloride, PET, or PET-G. The thickness of the middle substrate 23 is, for example, about 400 to 600 μm. Inside the frame of the middle substrate 23 is an opening hole in which the electronic module 10 is arranged. The electronic module 10 is temporarily fixed to the middle substrate 23 using several tapes 11b.
　接着層２４は、接着材を、中基材２３の枠内部に充填されて形成されることにより、電子モジュール１０を枠内部に保持する。電気基板１１の上側の接着層２４は、電気基板１１及び上シート２１間を接着する。なお、カバー４０（図２（Ｂ）参照）が存在する領域では、接着層２４は、カバー４０及び上シート２１間を接着する。一方、電気基板１１の下側の接着層２４は、電気基板１１及び下シート２２間を接着する。 The adhesive layer 24 holds the electronic module 10 inside the frame by being formed by filling the inside of the medium base material 23 with an adhesive. The adhesive layer 24 on the upper side of the electric substrate 11 adheres between the electric substrate 11 and the upper sheet 21. In the region where the cover 40 (see FIG. 2B) exists, the adhesive layer 24 bonds the cover 40 and the upper sheet 21 together. On the other hand, the adhesive layer 24 on the lower side of the electric substrate 11 bonds the electric substrate 11 and the lower sheet 22.
　ボタン部３０の構成について詳細に説明する。
　図２は、第１実施形態のボタン部３０近傍の構成を説明する図である。
　図２（Ａ）は、ボタン部３０近傍の平面図（図２（Ｂ）のａ－ａ部断面図）である。
　図２（Ｂ）は、ボタン部３０近傍の断面図（図１（Ｂ２）の矢印２ｂ部拡大図）である。 The configuration of the button unit 30 will be described in detail.
FIG. 2 is a diagram illustrating a configuration in the vicinity of the button unit 30 according to the first embodiment.
FIG. 2A is a plan view of the vicinity of the button portion 30 (a sectional view taken along the line aa in FIG. 2B).
FIG. 2B is a cross-sectional view in the vicinity of the button portion 30 (an enlarged view of the arrow 2b portion in FIG. 1B2).
　平面図において、ボタン部３０は、電気基板１１の配線パターン（図示せず）上に配置される。
　ボタン部３０は、ドームスイッチ３１、カバー４０、内接着部４１（カバー－ドーム間接着部）、外接着部４２（カバー－電気基板間接着部）を備える。
　ドームスイッチ３１は、導電性を有する金属により形成された、いわゆるメタルドームのスイッチである。ドームスイッチ３１は、ドーム状に形成されたドーム部３１ｂと、その全周につば部３１ｃ（周縁部）が形成されたような形状である。
　ドームスイッチ３１は、電気基板１１の直上に配置される。平面図において、ドームスイッチ３１の中央のほぼ円形の内部は、上面が押されることにより電気基板１１側に変形して可動する可動部である（図３（Ｂ）参照）。以下、この可動部をスイッチ可動部３１ａという。
　後述する内接着部４１の外形は、ドーム部３１ｂの外径よりも小さい。このため、ドーム部３１ｂの外径から内接着部４１の接着領域までの領域Ａ１は、接着剤等によって拘束されていない。 In the plan view, the button part 30 is arranged on a wiring pattern (not shown) of the electric substrate 11.
The button unit 30 includes a dome switch 31, a cover 40, an inner bonding portion 41 (cover-dome bonding portion), and an outer bonding portion 42 (cover-electric board bonding portion).
The dome switch 31 is a so-called metal dome switch formed of a conductive metal. The dome switch 31 has a shape in which a dome portion 31b formed in a dome shape and a collar portion 31c (peripheral portion) are formed on the entire circumference thereof.
The dome switch 31 is disposed immediately above the electric board 11. In the plan view, a substantially circular interior at the center of the dome switch 31 is a movable portion that is deformed and moved toward the electric substrate 11 when the upper surface is pressed (see FIG. 3B). Hereinafter, this movable part is referred to as a switch movable part 31a.
The outer shape of the inner bonding portion 41 described later is smaller than the outer diameter of the dome portion 31b. For this reason, the region A1 from the outer diameter of the dome portion 31b to the bonding region of the inner bonding portion 41 is not constrained by an adhesive or the like.
　また、スイッチ可動部３１ａの下面は、電気基板１１に接触して、電気基板１１の配線パターン同士（図示せず）を短絡させる電気接点である。スイッチ可動部３１ａは、特定のストロークだけ電気基板１１側に変形すると、電気基板１１側に凹むように、さらに変形し、下面中央部が電気基板１１に接地するようになっている。このため、ドームスイッチ３１は、この変形時において、利用者の操作力が急激に減る。これにより、ドームスイッチ３１は、利用者に対してクリック感、すなわちボタンを押した感覚を与えることができる。 Further, the lower surface of the switch movable portion 31a is an electrical contact that contacts the electrical substrate 11 and short-circuits the wiring patterns (not shown) of the electrical substrate 11. When the switch movable part 31a is deformed to the electric board 11 side by a specific stroke, the switch movable part 31a is further deformed so as to be dented to the electric board 11 side, and the central part of the lower surface is grounded to the electric board 11. For this reason, when the dome switch 31 is deformed, the user's operating force is drastically reduced. Thereby, the dome switch 31 can give a user a feeling of clicking, that is, a feeling of pressing a button.
　カバー４０は、ドームスイッチ３１よりも上側Ｚ２に配置された樹脂シート部材である。カバー４０の平面形状は、ドームスイッチ３１よりも大きく、外接着部４２の外形とほぼ等しい。
　カバー４０は、柔軟な材料により形成されており、その剛性が、ドームスイッチ３１に比較すると、十分に小さいものを用いる。これは、ボタン部３０の操作力への影響を小さくするためである。
　カバー４０の下面には、内接着部４１（カバー－ドーム間接着部）、外接着部４２（カバー－電気基板間接着部）が設けられている。 The cover 40 is a resin sheet member disposed on the upper side Z <b> 2 from the dome switch 31. The planar shape of the cover 40 is larger than that of the dome switch 31 and is substantially equal to the outer shape of the outer adhesive portion 42.
The cover 40 is made of a flexible material and has a sufficiently small rigidity compared to the dome switch 31. This is to reduce the influence on the operation force of the button unit 30.
On the lower surface of the cover 40, an inner adhesive portion 41 (cover-dome adhesive portion) and an outer adhesive portion 42 (cover-electric substrate adhesive portion) are provided.
　内接着部４１は、カバー４０及びドームスイッチ３１間を接着するための粘着材である。カバー４０及びドームスイッチ３１間のうち内接着部４１が設置されている領域は、両者間が実際に接着される接着領域である。内接着部４１は、例えば、基材を有する粘着シート、基材レス粘着シート等である。
　内接着部４１の平面形状は、円環の枠状である。内接着部４１の外径は、ドーム部３１ｂの外径よりも小さく、ドーム部３１ｂ上面の一部のみに配置され、つば部３１ｃ上面には配置されない。内接着部４１の中心は、ドームスイッチ３１の中心と一致している。
　このため、ドームスイッチ３１の頂点部には、内接着部４１の孔部が配置され、接着材が配置されないようになっている。また、内接着部４１は、カバー４０と、ドーム部３１ｂ上面の一部のみとを接着するようになっている。 The inner bonding portion 41 is an adhesive material for bonding between the cover 40 and the dome switch 31. The area where the inner adhesive portion 41 is installed between the cover 40 and the dome switch 31 is an adhesive area where the two are actually bonded. The inner adhesive portion 41 is, for example, a pressure-sensitive adhesive sheet having a base material, a base material-less pressure-sensitive adhesive sheet, or the like.
The planar shape of the inner adhesive portion 41 is an annular frame shape. The outer diameter of the inner bonding portion 41 is smaller than the outer diameter of the dome portion 31b, and is disposed only on a part of the upper surface of the dome portion 31b, and is not disposed on the upper surface of the collar portion 31c. The center of the inner adhesive portion 41 coincides with the center of the dome switch 31.
For this reason, the hole part of the inner adhesion part 41 is arrange | positioned in the vertex part of the dome switch 31, and an adhesive material is not arrange | positioned. The inner bonding portion 41 bonds the cover 40 and only a part of the upper surface of the dome portion 31b.
　これにより、ボタン部３０は、上下方向Ｚの高さを低くして、カード厚みを低減できる。すなわち、クレジットカード等のように、厚さが０．８ｍｍ程度の薄いものに、ドームスイッチを内蔵する場合には、ドームスイッチの頂点部の厚さをできるだけ低減する必要がある。このため、ドームスイッチの頂点部において、接着材の厚み（数μｍ～数十μｍ程度）を削減するだけでも、カード厚み低減に、大きく貢献できる。 Thereby, the button part 30 can make the height of the up-down direction Z low, and can reduce card | curd thickness. That is, when a dome switch is built in a thin one having a thickness of about 0.8 mm, such as a credit card, it is necessary to reduce the thickness of the top portion of the dome switch as much as possible. For this reason, simply reducing the thickness of the adhesive (about several μm to several tens of μm) at the apex of the dome switch can greatly contribute to reducing the card thickness.
　また、内接着部４１の外形は、ドームスイッチ３１の外形よりも小さい。このため、内接着部４１は、カバー４０と、ドームスイッチ３１上面の一部のみとを接着し、その接着面積が、十分に小さい。 Further, the outer shape of the inner adhesive portion 41 is smaller than the outer shape of the dome switch 31. For this reason, the inner adhesion part 41 adhere | attaches only the cover 40 and a part of upper surface of the dome switch 31, and the adhesion area is small enough.
　外接着部４２は、カバー４０と、電気基板１１とを接着する部材である。外接着部４２は、枠状のシート基材の上面及び下面に両面テープを貼付したり、粘着材を塗布して形成される。外接着部４２は、これらの粘着材により、カバー４０の下面に接着され、また、電気基板１１の上面に接着される。
　外接着部４２の形状は、内部に空間４２ａを有する枠体である。外接着部４２は、ドームスイッチ３１よりも外側に配置され、ドームスイッチ３１を囲うように配置されている。外接着部４２の空間４２ａには、接着層２４が充填されていない。 The outer bonding portion 42 is a member that bonds the cover 40 and the electric substrate 11. The outer adhesive portion 42 is formed by applying a double-sided tape on the upper and lower surfaces of the frame-shaped sheet base material or applying an adhesive material. The outer bonding portion 42 is bonded to the lower surface of the cover 40 by these adhesive materials, and is bonded to the upper surface of the electric substrate 11.
The shape of the outer bonding part 42 is a frame body having a space 42a inside. The outer adhesive portion 42 is disposed outside the dome switch 31 and is disposed so as to surround the dome switch 31. The adhesive layer 24 is not filled in the space 42 a of the outer adhesive portion 42.
　外接着部４２の厚みは、ドームスイッチ３１及び内接着部４１からなる厚みＬ１よりも大きい。このため、ボタン操作されていない状態では、ドームスイッチ３１は、電気基板１１との間に隙間を有し、電気基板１１から浮き上がった状態になっている。
　このような状態でも、ドームスイッチ３１は、カバー４０に接着しているので、空間４２ａ内で自由に移動することはない。このため、ボタン操作毎のクリック感は、ばらつきが小さく安定する。 The thickness of the outer bonding portion 42 is larger than the thickness L1 formed by the dome switch 31 and the inner bonding portion 41. For this reason, when the button is not operated, the dome switch 31 has a gap with the electric board 11 and is lifted from the electric board 11.
Even in such a state, since the dome switch 31 is adhered to the cover 40, it does not move freely in the space 42a. For this reason, the click feeling for each button operation has a small variation and is stable.

　図４は、比較例のボタン部１３０の動作を説明する断面図である。 FIG. 3 is a cross-sectional view for explaining the operation of the button unit 30 of the first embodiment.
FIG. 3A is a cross-sectional view illustrating a state where the upper sheet 21, the adhesive layer 24, the cover 40, and the dome switch 31 are deformed when the button corresponding region 21c on the upper surface of the upper sheet 21 is pressed.

FIG. 3C is an enlarged view (an enlarged view of the portion indicated by an arrow c in FIG. 3B) for explaining the deformation of the dome switch 31 and the cover 40.
FIG. 3D is an enlarged view (an enlarged view of a portion indicated by an arrow d in FIG. 3B) for explaining the deformation of the collar portion 31c.
FIG. 4 is a cross-sectional view illustrating the operation of the button unit 130 of the comparative example.
　図３（Ａ）に示すように、利用者の指によってボタン対応領域２１ｃが押圧されると、つまり、スイッチ操作されると、上シート２１、接着層２４及びカバー４０が電気基板１１側に変形する。これにより、ドームスイッチ３１は、スイッチ操作されている過程で、電気基板１１側に降下し、つば部３１ｃが電気基板１１に接地する。 As shown in FIG. 3A, when the button corresponding region 21c is pressed by the user's finger, that is, when the switch operation is performed, the upper sheet 21, the adhesive layer 24, and the cover 40 are deformed to the electric substrate 11 side. To do. Thereby, the dome switch 31 is lowered to the electric board 11 side during the switch operation, and the collar portion 31 c is grounded to the electric board 11.
　図３（Ｂ）に示すように、ボタン対応領域２１ｃがさらに押圧されると、上シート２１、接着層２４及びカバー４０が電気基板１１側に、さらに変形する。これにともない、スイッチ可動部３１ａは、電気基板１１側に降下し、特定の設定値分のストロークだけ変形すると、さらに変形し、クリック状態になる。
　この場合、本実施形態は、比較例よりも良好なクリック感を得られることを、試作により確認した。これは、以下の作用によるためと考えられる。 As shown in FIG. 3B, when the button corresponding region 21c is further pressed, the upper sheet 21, the adhesive layer 24, and the cover 40 are further deformed to the electric substrate 11 side. Accordingly, the switch movable portion 31a descends to the electric board 11 side, and when it is deformed by a stroke corresponding to a specific set value, the switch movable portion 31a is further deformed and enters a click state.
In this case, it was confirmed by trial manufacture that this embodiment can obtain a better click feeling than the comparative example. This is considered to be due to the following actions.
　前述したように、本実施形態のドームスイッチ３１は、上面の一部のみが内接着部４１を介してカバー４０に接着される形態であるため、変形時には、接着層２４の影響が小さい。つまり、ドームスイッチ３１は、面方向（図３（Ｃ）に示す矢印Ａ参照）及び上下方向Ｚにおいて、カバー４０に対してある程度自由に変形できる。そのため、ドームスイッチ３１は、接着層２４による拘束が小さい。 As described above, since the dome switch 31 of the present embodiment has a configuration in which only a part of the upper surface is adhered to the cover 40 via the inner adhesive portion 41, the influence of the adhesive layer 24 is small at the time of deformation. That is, the dome switch 31 can be freely deformed to some extent with respect to the cover 40 in the surface direction (see arrow A shown in FIG. 3C) and the vertical direction Z. Therefore, the dome switch 31 is less restricted by the adhesive layer 24.
　さらに、ドームスイッチ３１のつば部３１ｃは、電気基板１１に直接固定されない形態である。
　図３（Ｄ）に示すように、このため、つば部３１ｃは、ドームスイッチ３１の変形にともない、電気基板１１から反り上がるように変形できる。
　さらにまた、ドーム部３１ｂの領域Ａ１は、拘束されていない。このため、スイッチ可動部３１ａは、設計の狙い通りに変形しようとする。
　このように、本実施形態のドームスイッチ３１は、変形時の拘束が小さいので、設計の設定に近いクリック感を得られると考えられる。 Further, the collar portion 31 c of the dome switch 31 is not directly fixed to the electric board 11.
For this reason, as shown in FIG. 3D, the collar portion 31 c can be deformed so as to warp from the electric board 11 as the dome switch 31 is deformed.
Furthermore, the area A1 of the dome portion 31b is not constrained. For this reason, the switch movable part 31a tends to be deformed as designed.
As described above, the dome switch 31 of the present embodiment is considered to be able to obtain a click feeling close to the design setting since the constraint at the time of deformation is small.
　なお、試作は、種々の形態を作成した。試作は、例えば、ドーム部３１ｂの外径がφ６ｍｍ、内接着部４１の外径がφ４ｍｍとした形態でも、十分に良好なクリック感を得られた。 Note that various types of prototypes were created. In the trial production, for example, even when the outer diameter of the dome portion 31b is 6 mm and the outer diameter of the inner bonding portion 41 is 4 mm, a sufficiently good click feeling can be obtained.
　図４に示すように、一方、比較例のボタン部１３０は、カバー１４０の下面全面に接着部１４１が設けられている。ドームスイッチ１３１は、カバー１４０に覆われるようにして、電気基板１１１に取り付けられる。
　このため、ドームスイッチ１３１の上面全面が、カバー１４０の接着部１４１に接着している。そのため、ドームスイッチ１３１は、変形時には、カバー１４０の拘束が大きく、カバー１４０に対して自由に変形することができないため、接着層１２４の拘束が大きくなってしまう。
　さらに、ドームスイッチ１３１のつば部１３１ｃ周囲は、カバー１４０及び接着部１４１によって、電気基板１１１に対して固定されている。このため、ドームスイッチ１３１は、変形時には、電気基板１１１の拘束が大きくなってしまう。
　これにより、比較例のドームスイッチ１３１は、自らの変形が拘束されることにより、クリック感が、設計の設定とは大きく異なってしまう。 As shown in FIG. 4, the button part 130 of the comparative example is provided with an adhesive part 141 on the entire lower surface of the cover 140. The dome switch 131 is attached to the electric board 111 so as to be covered with the cover 140.
For this reason, the entire upper surface of the dome switch 131 is bonded to the bonding portion 141 of the cover 140. For this reason, when the dome switch 131 is deformed, the cover 140 is largely restrained and cannot be freely deformed with respect to the cover 140, and thus the restraint of the adhesive layer 124 becomes large.
Further, the periphery of the collar portion 131 c of the dome switch 131 is fixed to the electric substrate 111 by the cover 140 and the adhesive portion 141. For this reason, when the dome switch 131 is deformed, the restraint of the electric substrate 111 becomes large.
As a result, the dome switch 131 of the comparative example is constrained in its deformation, so that the click feeling is greatly different from the design setting.
　次に、本実施形態のカード２０の製造方法について説明する。
　図５は、第１実施形態のカード製造工程を説明する断面図である。
　カード２０の製造は、製造機械、作業者等が以下の工程に従って行なう。以下、簡略して１枚のカード２０を製造する場合を説明するが、実際のカード製造は、多面付けにより行なう。
（１）ドーム配置工程
　カバー４０下面の内接着部４１にドームスイッチ３１を予め接着して一体にし、これを電気基板１１に配置する（図２（Ｂ）参照）。このように一体にすることで、ドームスイッチ３１を電気基板１１上に配置する作業が簡単にできる。
　外接着部４２は、カバー４０下面に予め接着しておいてもよいし、又は電気基板１１に予め接着しておいてもよい。
　これにより、表示部１２等が実装された電気基板１１と、ドームスイッチ３１、カバー４０、接着部４１，４２とからなるアッセンブリが製造される（図１（Ａ）参照）。
（２）仮固定工程
　図１（Ｂ）に示すように、電子モジュール１０を、数枚のテープ１１ｂを用いて、中基材２３に仮固定する。
（３）ラミネート工程
　図５（Ａ）に示すように、上シート２１と電子モジュール１０及び中基材２３との間に、接着層２４に形成される接着材２４ａを充填し、同様に、下シート２２と電子モジュール１０及び中基材２３との間に、接着材２４ａを充填した積層体２０ａを形成する。この接着材２４ａには、充填可能な程度に、粘性が低い液状のものを用いる。
　そして、この積層体２０ａを、ローラ６０ａ，６０ｂ間を通して、所定の厚さにするとともに、余分な接着材２４ａを外部に排出する。
　なお、空間４２ａは、接着材等により密閉されているので、ラミネート工程における接着材２４ａの流入が抑制される。 Next, the manufacturing method of the card | curd 20 of this embodiment is demonstrated.
FIG. 5 is a cross-sectional view illustrating the card manufacturing process of the first embodiment.
The card 20 is manufactured by a manufacturing machine, an operator, etc. according to the following steps. Hereinafter, although the case where one card | curd 20 is manufactured simply is demonstrated, actual card | curd manufacture is performed by multiple imposition.
(1) Dome Arrangement Step The dome switch 31 is bonded in advance to the inner adhesive portion 41 on the lower surface of the cover 40 so as to be integrated on the electric substrate 11 (see FIG. 2B). Such integration makes it easy to arrange the dome switch 31 on the electric board 11.
The outer bonding part 42 may be bonded to the lower surface of the cover 40 in advance, or may be bonded to the electric substrate 11 in advance.
As a result, an assembly including the electric board 11 on which the display unit 12 and the like are mounted, the dome switch 31, the cover 40, and the bonding portions 41 and 42 is manufactured (see FIG. 1A).
(2) Temporary Fixing Step As shown in FIG. 1 (B), the electronic module 10 is temporarily fixed to the middle base material 23 using several tapes 11b.
(3) Laminating Step As shown in FIG. 5A, an adhesive 24a formed on the adhesive layer 24 is filled between the upper sheet 21, the electronic module 10, and the middle base material 23. Similarly, Between the sheet | seat 22, the electronic module 10, and the intermediate | middle base material 23, the laminated body 20a with which the adhesive material 24a was filled is formed. The adhesive 24a is made of a liquid that has a low viscosity enough to be filled.
Then, the laminated body 20a is passed through between the rollers 60a and 60b so as to have a predetermined thickness, and excess adhesive 24a is discharged to the outside.
Since the space 42a is sealed with an adhesive or the like, the inflow of the adhesive 24a in the laminating process is suppressed.
（４）加圧保持工程（エージング）
　図５（Ｂ）に示すように、上シート２１及び下シート２２をプレス板６１ａ，６２ｂで加圧して、積層体２０ａが変形しない程度に接着材２４ａが固着するまでの時間、保持する。
　この加圧保工程において、外接着部４２は、ボタン部３０にかかる圧力の大部分を受け止める。このため、外接着部４２の内部の空間４２ａが維持され、ドームスイッチ３１は、電気基板１１から浮いた状態を維持でき、変形を抑制できる。 (4) Pressure holding process (aging)
As shown in FIG. 5B, the upper sheet 21 and the lower sheet 22 are pressed by the press plates 61a and 62b and held for a time until the adhesive 24a is fixed to the extent that the stacked body 20a is not deformed.
In the pressurizing and maintaining step, the outer adhesive portion 42 receives most of the pressure applied to the button portion 30. For this reason, the space 42a inside the outer adhesion part 42 is maintained, the dome switch 31 can maintain the state which floated from the electric board 11, and can suppress a deformation | transformation.
（５）加圧解放工程
　プレス板６１ａ，６２ｂを駆動して、積層体２０ａを圧力から解放する。この場合、上記（４）での工程において、ドームスイッチ３１は、変形を抑制できているので、積層体２０ａを解放した場合、復元しようとすることはない。
　このため、本実施形態の積層体２０ａ（カード２０）は、表面を平滑にでき、外観を向上できる。また、カード２０は、例えば、携行時に他のカードに積層された場合に、不用意なボタン操作を抑制できる。
　その後、積層体２０ａは、カード外形で形打ち抜き加工され、最終形態であるカード２０が製造される。 (5) Pressure release process The press plates 61a and 62b are driven to release the laminate 20a from the pressure. In this case, in the step (4), since the dome switch 31 can suppress deformation, when the stacked body 20a is released, there is no attempt to restore it.
For this reason, the laminated body 20a (card | curd 20) of this embodiment can make the surface smooth, and can improve an external appearance. Moreover, the card 20 can suppress an inadvertent button operation, for example, when it is stacked on another card at the time of carrying.
Thereafter, the stacked body 20a is stamped with a card outer shape, and the card 20 as a final form is manufactured.
　一方、比較例のカードは、外接着部４２を有していない。このため、ラミネート工程、加圧工程等において、上シート１２１及び下シートにかかる圧力がドームスイッチ１３１の上面に加わり、スイッチ可動部１３１ａが下側Ｚ１に変形してしまう。この状態で、加圧解除工程において、上シート１２１及び下シートにかかる圧力を解放すると、復元力によってスイッチ可動部１３１ａが上側Ｚ２に変形し、上シート１２１の上面が盛り上がってしまう。
　このため、比較例のカードは、外観が低下してしまう。 On the other hand, the card of the comparative example does not have the outer bonding portion 42. For this reason, in the laminating process, the pressing process, and the like, pressure applied to the upper sheet 121 and the lower sheet is applied to the upper surface of the dome switch 131, and the switch movable part 131a is deformed to the lower side Z1. In this state, when the pressure applied to the upper sheet 121 and the lower sheet is released in the pressure release process, the switch movable portion 131a is deformed to the upper side Z2 by the restoring force, and the upper surface of the upper sheet 121 is raised.
For this reason, the appearance of the card of the comparative example is degraded.
　以上説明したように、本実施形態のカード２０は、カード厚みを薄くでき、また、クリック感を向上でき、さらに、製造時には、ドームスイッチ３１を電気基板１１上に配置する場合の工程が簡単であり、かつ、ボタン部３０の盛り上がりを抑制し、平坦に形成できる。 As described above, the card 20 of the present embodiment can reduce the card thickness, improve the click feeling, and can simplify the process for arranging the dome switch 31 on the electric board 11 at the time of manufacture. In addition, the button part 30 can be prevented from rising and can be formed flat.
（第２実施形態）
　次に、本発明の第２実施形態について説明する。
　なお、以下の各実施形態の説明及び図面において、前述した第１実施形態と同様の機能を果たす部分には、同一の符号又は末尾（下２桁）に同一の符号を付して、重複する説明を適宜省略する。
　図６は、第２実施形態のボタン部２３０近傍の構成を説明する図である（図２に相当する図）。
　第２実施形態の内接着部２４１（カバー－ドーム間接着部）の平面形状は、矩形である。平面形状において、内接着部２４１は、ドームスイッチ３１の中心領域以外に、配置される。つまり、内接着部２４１は、ドームスイッチ３１の頂点部を避けて、配置される。このため、ドームスイッチ３１の頂点部には、第１実施形態と同様に、接着材が配置されないようになっている。
　これにより、ボタン部２３０は、第１実形態と同様に、上下方向Ｚの高さを低くして、カード厚みを低減できる。その他の効果は、第１実形態と同様である。 (Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the following description and drawings of the respective embodiments, the same reference numerals or parts (the last two digits) are assigned the same reference numerals to the same functions as those of the first embodiment described above, and are duplicated. Description is omitted as appropriate.
FIG. 6 is a diagram illustrating a configuration in the vicinity of the button unit 230 of the second embodiment (a diagram corresponding to FIG. 2).
The planar shape of the inner adhesive portion 241 (cover-dome adhesive portion) of the second embodiment is a rectangle. In the planar shape, the inner adhesive portion 241 is disposed outside the central region of the dome switch 31. That is, the inner adhesive portion 241 is disposed avoiding the apex portion of the dome switch 31. For this reason, the adhesive material is not disposed at the apex of the dome switch 31 as in the first embodiment.
Thereby, the button part 230 can make the height of the up-down direction Z low, and can reduce card | curd thickness similarly to the 1st real form. Other effects are the same as in the first embodiment.
　なお、内接着部２４１の平面形状は、矩形に限定されずその他の形状（円形等）でもよい。
　また、内接着部２４１がドームスイッチ３１の中心をずらして配置されるため、ドームスイッチ３１は、電気基板１１から傾いて浮きあがるように配置される場合がある。この場合でも、ドームスイッチ３１は、ボタン操作される場合には、つば部３１ｃが電気基板１１に接地するので、問題はない。 The planar shape of the inner adhesive portion 241 is not limited to a rectangle, and may be another shape (such as a circle).
In addition, since the inner adhesive portion 241 is disposed with the center of the dome switch 31 being shifted, the dome switch 31 may be disposed so as to be inclined and lifted from the electric board 11. Even in this case, when the button of the dome switch 31 is operated, there is no problem because the collar portion 31c is grounded to the electric board 11.
（第３実施形態）
　次に、本発明の第３実施形態について説明する。
　図７は、第３実施形態のボタン部３３０近傍の構成を説明する図である（図２に相当する図）。
　カバー３４０の下面全面は、接着部３４１ａが設けられている。接着部３４１ａは、カバー３４０に両面テープを貼付したり、粘着材を塗布して形成される。
　接着部３４１ａの下面には、円環シート３４３が接着されている。円環シート３４３自体は、粘着性を有さない。円環シート３４３の平面形状は、円環状（枠状）である。円環シート３４３の中心は、ドームスイッチ３１の中心に一致している。
　内接着部３４１（カバー－ドーム間接着部）は、接着部３４１ａのうちこの円環シート３４３の孔部から露出した部分により形成される。内接着部３４１は、接着部３４１ａのうちドームスイッチ３１に実際に接着する接着領域である。
　外接着部３４２の厚みは、ドームスイッチ３１の厚みＬ３０１より大きい。このため、ドームスイッチ３１は、第１実施形態と同様に、電気基板１１から浮き上がった状態になっている。 (Third embodiment)
Next, a third embodiment of the present invention will be described.
FIG. 7 is a diagram illustrating a configuration in the vicinity of the button unit 330 according to the third embodiment (a diagram corresponding to FIG. 2).
An adhesive portion 341 a is provided on the entire lower surface of the cover 340. The adhesive portion 341a is formed by applying a double-sided tape to the cover 340 or applying an adhesive material.
An annular sheet 343 is bonded to the lower surface of the bonding portion 341a. The annular sheet 343 itself does not have adhesiveness. The planar shape of the annular sheet 343 is an annular shape (frame shape). The center of the annular sheet 343 coincides with the center of the dome switch 31.
The inner adhesive portion 341 (cover-dome adhesive portion) is formed by a portion of the adhesive portion 341a exposed from the hole of the annular sheet 343. The inner bonding portion 341 is a bonding region that is actually bonded to the dome switch 31 in the bonding portion 341a.
The thickness of the outer adhesive portion 342 is larger than the thickness L301 of the dome switch 31. For this reason, the dome switch 31 is in a state of being lifted from the electric board 11 as in the first embodiment.
　上記構成により、ドームスイッチ３１は、その頂点部が、円環シート３４３の孔部に露出した内接着部３４１に接着するようになっている。これにより、ドームスイッチ３１の上面の一部のみが、内接着部３４１に接着し、カバー３４０に保持される。 With the above configuration, the dome switch 31 has its apex portion bonded to the inner bonding portion 341 exposed in the hole portion of the annular sheet 343. Thereby, only a part of the upper surface of the dome switch 31 is bonded to the inner bonding portion 341 and is held by the cover 340.
　このように、ドームスイッチ３１は、その一部のみが内接着部３４１に接着されるので、第１実施形態と同様に、良好なクリック感を得ることができる。 Thus, since only a part of the dome switch 31 is adhered to the inner adhesive portion 341, a good click feeling can be obtained as in the first embodiment.
（第４実施形態）
　次に、本発明の第４実施形態について説明する。
　図８は、第４実施形態のボタン部４３０近傍の構成を説明する図である。
　図８（Ａ）は、内接着部４４１、外接着部４４２等の配置を説明する平面図である。
　図８（Ｂ）は、ボタン部４３０近傍の断面図である。
　第４実施形態の外接着部４４２は、厚さが十分に小さい。外接着部４４２の厚さは、例えば、内接着部４４１の厚さと、ほぼ同じである。
　このため、カバー４４０は、内接着部４４１、外接着部４３２以外の領域では、ドームスイッチ３１にほぼ密着する。なお、図８（Ｂ）は、層構成を明確にするために、ドームスイッチ３１及びカバー４４０に隙間を有するように図示するが、この隙間は、実際には、ほとんどない。 (Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
FIG. 8 is a diagram illustrating a configuration in the vicinity of the button unit 430 according to the fourth embodiment.
FIG. 8A is a plan view illustrating the arrangement of the inner bonding portion 441, the outer bonding portion 442, and the like.
FIG. 8B is a cross-sectional view in the vicinity of the button portion 430.
The outer adhesive portion 442 of the fourth embodiment has a sufficiently small thickness. The thickness of the outer bonding portion 442 is substantially the same as the thickness of the inner bonding portion 441, for example.
For this reason, the cover 440 is in close contact with the dome switch 31 in a region other than the inner adhesive portion 441 and the outer adhesive portion 432. In FIG. 8B, the dome switch 31 and the cover 440 are illustrated as having a gap in order to clarify the layer configuration.
　このため、ボタン部４３０は、前述した実施形態のような空間４２ａ（図２（Ｂ）等参照）を有さない。
　上記構成により、ドームスイッチ３１は、前述した実施形態と同様に、接着層２４に直接接着しておらず、また、一部のみがカバー４４０に接着されている。さらに、つば部３１ｃは、電気基板１１に接しているものの、電気基板１１に直接接着されていない。
　このため、変形時において、ドームスイッチ３１は、前述した実施形態と同様に、カバー４０に対してある程度自由に変形できる（第１実施形態の図３（Ｃ）参照）。
　これにより、ボタン部４３０は、良好なクリック感を得られるともに、カード厚みをさらに低減できる。 For this reason, the button part 430 does not have the space 42a (refer FIG. 2 (B) etc.) like embodiment mentioned above.
With the above configuration, the dome switch 31 is not directly bonded to the adhesive layer 24 as in the above-described embodiment, and only a part is bonded to the cover 440. Further, although the collar portion 31 c is in contact with the electric substrate 11, it is not directly bonded to the electric substrate 11.
For this reason, at the time of deformation, the dome switch 31 can be freely deformed to some extent with respect to the cover 40 as in the above-described embodiment (see FIG. 3C of the first embodiment).
Thereby, the button part 430 can further reduce card | curd thickness while obtaining a favorable click feeling.
（第５実施形態）
　次に、本発明の第５実施形態について説明する。
　図９は、第５実施形態のボタン部５３０近傍の構成を説明する図である（図２に相当する図）。
　第５実施形態では、外接着部５４２の厚さを、第１実施形態から変更した。
　外接着部５４２の厚みＬ５０１は、ドームスイッチ３１、内接着部５４１からなる厚みよりも、若干小さい。このため、ボタン操作されていない状態であっても、カバー５４０のうちドームスイッチ３１の頂点部の領域５４０ａが、接着層２４側に突出するように湾曲している。
　この場合でも、カード製造後には、カード上面が十分に平滑にできることを、試作により確認した。
　これは、外接着部５４２は、厚みが小さくても、カード製造工程内の加圧時において、ドームスイッチ３１にかかる圧力を、ある程度低減できるためであると考えられる。
　また、第１実施形態と同様に、つば部３１ｃは、拘束が小さい。このため、カード製造後には、ボタン部５３０のクリック感は、良好であることも確認した。 (Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
FIG. 9 is a diagram illustrating a configuration in the vicinity of the button unit 530 according to the fifth embodiment (a diagram corresponding to FIG. 2).
In the fifth embodiment, the thickness of the outer adhesive portion 542 is changed from the first embodiment.
The thickness L501 of the outer adhesive portion 542 is slightly smaller than the thickness composed of the dome switch 31 and the inner adhesive portion 541. For this reason, even when the button is not operated, the region 540a at the apex of the dome switch 31 in the cover 540 is curved so as to protrude toward the adhesive layer 24 side.
Even in this case, it was confirmed by trial production that the upper surface of the card could be sufficiently smooth after the card was manufactured.
This is considered to be because the pressure applied to the dome switch 31 can be reduced to some extent at the time of pressurization in the card manufacturing process even if the outer adhesive portion 542 is small in thickness.
Further, as in the first embodiment, the collar portion 31c is less constrained. For this reason, after card manufacture, it confirmed that the click feeling of button part 530 was also good.
　これにより、本実施形態のカードは、カード厚みをより低減できる。
　なお、第２、第３実施形態も、本実施形態と同様に、外接着部の厚みを小さくしてもよい。この場合にも、本実施形態と同様な効果を奏することを期待できる。 Thereby, the card | curd of this embodiment can reduce card | curd thickness more.
In the second and third embodiments, the thickness of the outer adhesive portion may be reduced as in the present embodiment. Also in this case, it can be expected that the same effects as those of the present embodiment can be obtained.
（第６実施形態）
　次に、本発明の第６実施形態について説明する。
　第６実施形態のボタン部６３０は、第３実施形態の構成を変更したものである。
　なお、第６実施形態の説明及び図面において、前述した第３実施形態と同様の機能を果たす部分には、同一の符号を適宜付して、重複する説明を適宜省略する。
　図１０は、第６実施形態のボタン部６３０近傍の構成を説明する図である。
　図１０（Ａ）は、ボタン部６３０が操作されていない状態を示す図である。
　図１０（Ｂ）は、ボタン部６３０が操作された状態を示す図である。 (Sixth embodiment)
Next, a sixth embodiment of the present invention will be described.
The button unit 630 of the sixth embodiment is obtained by changing the configuration of the third embodiment.
Note that, in the description of the sixth embodiment and the drawings, the same reference numerals are given to portions that perform the same functions as those of the above-described third embodiment, and overlapping descriptions are omitted as appropriate.
FIG. 10 is a diagram illustrating a configuration in the vicinity of the button unit 630 according to the sixth embodiment.
FIG. 10A is a diagram illustrating a state where the button unit 630 is not operated.
FIG. 10B is a diagram illustrating a state where the button unit 630 is operated.
　図１０（Ａ）に示すように、ボタン部６３０は、第３実施形態から円環シート３４３を削除したものである。ボタン部６３０のその他の形態は、第３実施形態と同様である。
　図１０（Ａ）、図１０（Ｂ）に示すように、内接着部３４１の大きさは、ボタン操作されていない状態と、ボタン操作された状態とでは異なる。
　このため、ドーム部３１ｂの外径から内接着部３４１の接着領域までの領域Ａ１の大きさは、ボタン操作されていない状態と、ボタン操作された状態とでは異なる。ボタン部６３０の領域Ａ１の大きさは、ボタン操作された状態でも、十分に大きい。そのため、ボタン操作時において、ドーム部３１ｂの変形が容易である。これにより、ボタン部６３０は、良好なクリック感を、利用者に与えることができる。 As illustrated in FIG. 10A, the button unit 630 is obtained by deleting the annular sheet 343 from the third embodiment. The other form of the button part 630 is the same as that of 3rd Embodiment.
As shown in FIGS. 10A and 10B, the size of the inner adhesive portion 341 is different between a state where the button is not operated and a state where the button is operated.
For this reason, the size of the region A1 from the outer diameter of the dome portion 31b to the bonding region of the inner bonding portion 341 is different between the state where the button is not operated and the state where the button is operated. The size of the area A1 of the button unit 630 is sufficiently large even when the button is operated. Therefore, the dome portion 31b can be easily deformed during button operation. Thereby, the button part 630 can give a favorable click feeling to a user.
　なお、図１０（Ａ）、図１０（Ｂ）は、模式的な断面図である。このため、実際には、接着部３４１ａに撓みによって、ボタン操作されていない状態と、ボタン操作された状態とで、内接着部３４１の大きさの変化が、明確ではない場合も有りうる。この場合でも、ボタン操作された状態での領域Ａ１の大きさが十分に大きいので、ボタン部６３０は、良好なクリック感を、利用者に与えることができる。 10A and 10B are schematic cross-sectional views. Therefore, in practice, there may be a case where the change in the size of the inner adhesive portion 341 between the state where the button is not operated and the state where the button is operated is not clear due to the bending of the adhesive portion 341a. Even in this case, since the size of the area A1 when the button is operated is sufficiently large, the button unit 630 can give the user a good click feeling.
（第７実施形態）
　次に、本発明の第７実施形態について説明する。
　第７実施形態のボタン部７３０は、第６実施形態の構成を変更したものである。
　なお、第７実施形態の説明及び図面において、前述した第６実施形態と同様の機能を果たす部分には、同一の符号を適宜付して、重複する説明を適宜省略する。
　図１１は、第７実施形態のボタン部７３０近傍の構成を説明する図である。
　本実施形態は、接着部３４１ａの外形を、第６実施形態よりも小さくした。
　接着部３４１ａの外径は、ドーム部３１ｂとほぼ同じである。
　なお、外接着部３４２及びカバー３４０間は、第１実施形態と同様に、粘着材等により接着される。 (Seventh embodiment)
Next, a seventh embodiment of the present invention will be described.
The button unit 730 of the seventh embodiment is a modification of the configuration of the sixth embodiment.
Note that, in the description of the seventh embodiment and the drawings, the same reference numerals are given to portions that perform the same functions as those of the above-described sixth embodiment, and overlapping descriptions are omitted as appropriate.
FIG. 11 is a diagram illustrating a configuration in the vicinity of the button unit 730 according to the seventh embodiment.
In the present embodiment, the outer shape of the bonding portion 341a is smaller than that of the sixth embodiment.
The outer diameter of the bonding portion 341a is substantially the same as that of the dome portion 31b.
In addition, between the outer adhesion part 342 and the cover 340, it adhere | attaches with an adhesive material etc. similarly to 1st Embodiment.
　本実施形態のドーム部３１ｂ及び内接着部３４１間が接着される態様（接着面積等）は、第６実施形態と同様である。このため、本実施形態のドーム部３１ｂの外径から内接着部３４１の接着領域までの領域Ａ１の大きさについても、第６実施形態と同様である。
　これにより、本実施形態のボタン部７３０は、第６実施形態と同様に、良好なクリック感を、利用者に与えることができる。 The aspect (adhesion area etc.) where the dome part 31b and the inner adhesion part 341 of this embodiment are adhere | attached is the same as that of 6th Embodiment. For this reason, the size of the region A1 from the outer diameter of the dome portion 31b to the bonding region of the inner bonding portion 341 in the present embodiment is also the same as in the sixth embodiment.
Thereby, the button part 730 of this embodiment can give a favorable click feeling to a user similarly to 6th Embodiment.
（第８実施形態）
　次に、本発明の第８実施形態について説明する。
　第８実施形態のボタン部８３０は、第３実施形態の構成を変更したものである。
　なお、第８実施形態の説明及び図面において、前述した第３実施形態と同様の機能を果たす部分には、同一の符号を適宜付して、重複する説明を適宜省略する。
　図１２は、第８実施形態のボタン部８３０近傍の構成を説明する図である。
　本実施形態は、円環シート８４３の外形を、第３実施形態よりも大きくした。
　円環シート８４３の外形は、ドームスイッチ３１よりも大きい。円環シート８４３は、ドームスイッチ３１を覆うように配置される。
　このため、ドームスイッチ３１の表面のうち円環シート８４３によって覆われる領域は、内接着部３４１ａに接着されることがない。このため、ドーム部３１ｂのうち接着部３４１で拘束されない領域、つまり、接着部３４１よりも外側の領域は、拘束されない状態を安定して維持できる。そのため、ボタン操作時において、ドーム部３１ｂは、より確実に変形できるようになる。
　これにより、ボタン部８３０は、良好なクリック感を、利用者に与えることができる。 (Eighth embodiment)
Next, an eighth embodiment of the present invention will be described.
The button unit 830 of the eighth embodiment is obtained by changing the configuration of the third embodiment.
Note that in the description of the eighth embodiment and the drawings, the same reference numerals are given to portions that perform the same functions as those of the third embodiment described above, and overlapping descriptions are omitted as appropriate.
FIG. 12 is a diagram illustrating a configuration in the vicinity of the button unit 830 according to the eighth embodiment.
In the present embodiment, the outer shape of the annular sheet 843 is made larger than that in the third embodiment.
The outer shape of the annular sheet 843 is larger than that of the dome switch 31. The annular sheet 843 is disposed so as to cover the dome switch 31.
For this reason, the region covered with the annular sheet 843 on the surface of the dome switch 31 is not bonded to the inner bonding portion 341a. For this reason, the area | region which is not restrained by the adhesion part 341 among the dome parts 31b, ie, the area | region outside the adhesion part 341, can maintain stably the state which is not restrained. Therefore, the dome portion 31b can be more reliably deformed during button operation.
Thereby, the button part 830 can give a favorable click feeling to a user.
　以上、本発明の実施形態について説明したが、本発明は前述した実施形態に限定されるものではなく、後述する変形形態のように種々の変形や変更が可能であって、それらも本発明の技術的範囲内である。また、実施形態に記載した効果は、本発明から生じる最も好適な効果を列挙したに過ぎず、本発明による効果は、実施形態に記載したものに限定されない。なお、前述した実施形態及び後述する変形形態は、適宜組み合わせて用いることもできるが、詳細な説明は省略する。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and changes can be made as in the modifications described later.
