A pair of elastically deformable elastic locking pieces 3a, 3a, which are opposed to each other, are integrally formed on a side wall forming an opening at an end of the case 3 on the operator facing surface side. The elastic locking piece 3a is snap-fit fixed to a mounting hole of an interior component such as an instrument panel provided in front of a steering wheel (not shown).
ケース３の操作者対向面側の開口には、操作者による押圧操作を受けるキャップ状の押圧操作部２と、押圧操作部２を取り囲みつつ押圧操作部２との間にスイッチ収容部となる空間を提供する操作部ホルダ５とが設けられている。操作部ホルダ５は、押圧操作部２を中心軸線ＣＬに沿って往復移動可能に保持している。押圧操作部２及び操作部ホルダ５の周囲には、ベゼル６が組み付けられている。 In the opening on the side of the case 3 facing the operator, a cap-shaped pressing operation unit 2 receiving a pressing operation by the operator, and a space serving as a switch housing between the pressing operation unit 2 while surrounding the pressing operation unit 2. Is provided. The operation unit holder 5 holds the pressing operation unit 2 so as to be able to reciprocate along the central axis CL. A bezel 6 is assembled around the pressing operation unit 2 and the operation unit holder 5.
図１Ａ及び図２に示すように、操作部ホルダ５の内部底面には、押圧操作部２の押圧操作を検出する検出部となるスイッチ７が設けられている。図示例では、３個のスイッチ７が中心軸線ＣＬを中心とする同一円周上に等間隔に配置されている。 As shown in FIGS. 1A and 2, a switch 7 serving as a detection unit that detects a pressing operation of the pressing operation unit 2 is provided on the inner bottom surface of the operation unit holder 5. In the illustrated example, three switches 7 are arranged at equal intervals on the same circumference around the center axis CL.
スイッチ７は、配線基板８に設けられた固定接点に対し、弾性変形して座屈するドーム状のラバーコンタクト９の内部底面に設けられた可動接点が接離するラバーコンタクトスイッチとして構成されている。固定接点には、配線基板８の裏面側に配置された配線接続用コネクタ１０が電気的に接続されている。 The switch 7 is configured as a rubber contact switch in which a movable contact provided on the inner bottom surface of a dome-shaped rubber contact 9 that elastically deforms and buckles with respect to a fixed contact provided on the wiring board 8 comes into contact with or separates from the fixed contact.

押圧操作部２の裏面には、生体情報センサ１１が配置されている。ラバーコンタクト９は、生体情報センサ１１の裏面に配置されている。これにより、ラバーコンタクト９の可動は、押圧操作部２の裏面のごく一部に限定されている。 A biological information sensor 11 is arranged on the back surface of the pressing operation unit 2. The rubber contact 9 is arranged on the back surface of the biological information sensor 11. Thereby, the movement of the rubber contact 9 is limited to a very small part of the back surface of the pressing operation unit 2.
図１Ｂの矢印Ａ方向に押圧操作部２を押圧操作することで、ラバーコンタクト９の可動接点と配線基板８の固定接点とが当接して接触することとなり、ラバーコンタクトスイッチはスイッチオン状態となる。押圧操作部２の押圧操作が解除されたときは、ラバーコンタクト９が弾性復元力により元のドーム形状に自動復帰する。ラバーコンタクト９の可動接点が配線基板８の固定接点から離れることになり、ラバーコンタクトスイッチはスイッチオフ状態となる。 When the pressing operation unit 2 is pressed in the direction of arrow A in FIG. 1B, the movable contact of the rubber contact 9 comes into contact with the fixed contact of the wiring board 8 so that the rubber contact switch is turned on. . When the pressing operation of the pressing operation unit 2 is released, the rubber contact 9 automatically returns to the original dome shape by the elastic restoring force. The movable contact of the rubber contact 9 is separated from the fixed contact of the wiring board 8, and the rubber contact switch is turned off.
生体情報センサ１１は、押圧操作部２を押圧操作する操作者の手指の指紋や静脈の生体情報を検出するものである。生体情報センサ１１の検出方式としては、静電容量式や光学式などのいずれかの検出方式が用いられる。 The biological information sensor 11 detects the fingerprint of the finger of the operator who presses the pressing operation unit 2 and the biological information of the vein. As a detection method of the biological information sensor 11, any one of a capacitance type and an optical type is used.
生体情報センサ１１のセンサ基板には、フレキシブル配線１２が電気的に接続されている。フレキシブル配線１２としては、導体を平行に並べた配線材であるフレキシブルフラットケーブル（ＦＦＣ）、又は銅箔からなる配線パターンが形成されたフレキシブルプリント配線板（ＦＰＣ）等が用いられる。 The flexible wiring 12 is electrically connected to the sensor substrate of the biological information sensor 11. As the flexible wiring 12, a flexible flat cable (FFC), which is a wiring material in which conductors are arranged in parallel, a flexible printed wiring board (FPC) on which a wiring pattern made of copper foil is formed, or the like is used.
押圧操作部２、スイッチ７、及び生体情報センサ１１は、操作部ホルダ５内に集約化して配置される一方、操作部ホルダ５の裏面近傍には、スイッチ７及び生体情報センサ１１と電気的に接続する制御基板１３が押圧操作方向に沿って配置されている。なお、スイッチ７としては、ラバーコンタクトスイッチに代えて、マイクロスイッチ等の機械式接点を用いたスイッチなどを用いることができる。 The pressing operation unit 2, the switch 7, and the biological information sensor 11 are collectively arranged in the operation unit holder 5, while the switch 7 and the biological information sensor 11 are electrically connected to the vicinity of the back surface of the operation unit holder 5. The control board 13 to be connected is arranged along the pressing operation direction. Note that, as the switch 7, a switch using a mechanical contact such as a microswitch can be used instead of the rubber contact switch.
図３に示すように、ケース３の内部に中心軸線ＣＬに沿って形成された帯状の嵌合溝３ｂには、筒状の基板ホルダ４が嵌合固定されている。基板ホルダ４の内部には、帯状の嵌合溝４ａが中心軸線ＣＬに沿って形成されている。嵌合溝４ａには、両面実装基板である制御基板１３が嵌合固定されている。制御基板１３は、押圧操作部２及び生体情報センサ１１の移動に対して固定された位置に配置されている。 As shown in FIG. 3, a tubular substrate holder 4 is fitted and fixed in a band-like fitting groove 3b formed inside the case 3 along the central axis CL. Inside the substrate holder 4, a band-like fitting groove 4a is formed along the central axis CL. A control board 13 which is a double-sided mounting board is fitted and fixed in the fitting groove 4a. The control board 13 is disposed at a position fixed with respect to the movement of the pressing operation unit 2 and the biological information sensor 11.
制御基板１３の操作者対向面側の一端部における一方の面には、配線接続用コネクタ１０が固定されており、一方の面とは反対側の他方の面には、センサ接続用コネクタ１４が固定されている。制御基板１３の他端部における一方の面には、外部の制御装置等と電気的に接続される外部接続用コネクタ１５が固定されている。これにより、制御基板１３を集約化して接続部の構成とスイッチ装置１の内部空間とを簡素化することができる。 A wiring connector 10 is fixed to one surface of one end of the control board 13 on the operator-facing surface side, and a sensor connection connector 14 is provided on the other surface opposite to the one surface. Fixed. An external connection connector 15 that is electrically connected to an external control device or the like is fixed to one surface of the other end of the control board 13. Thereby, the control board 13 can be centralized, and the configuration of the connection portion and the internal space of the switch device 1 can be simplified.
配線接続用コネクタ１０には、スイッチ７の固定接点が電気的に接続されている。センサ接続用コネクタ１４には、フレキシブル配線１２を介して生体情報センサ１１が電気的に接続されている。生体情報センサ１１のフレキシブル配線１２を制御基板１３の操作者対向面側の一端部に接続することができるので、他部品との干渉を回避することができる。 The fixed contact of the switch 7 is electrically connected to the wiring connection connector 10. The biological information sensor 11 is electrically connected to the sensor connector 14 via the flexible wiring 12. Since the flexible wiring 12 of the biometric information sensor 11 can be connected to one end of the control board 13 on the side facing the operator, interference with other components can be avoided.
図１Ｂに示すように、押圧操作部２を押圧操作したとき、生体情報センサ１１のフレキシブル配線１２は、押圧操作部２の移動に追従して撓み変形する。この撓み変形により生体情報センサ１１に作用する反力を吸収することができる。 As shown in FIG. 1B, when the pressing operation unit 2 is pressed, the flexible wiring 12 of the biological information sensor 11 bends and deforms following the movement of the pressing operation unit 2. The reaction force acting on the biological information sensor 11 can be absorbed by this bending deformation.
制御基板１３には、スイッチ７及び生体情報センサ１１からの信号を処理する制御部１６等が実装されている。制御部１６は、ＣＰＵ、ＲＯＭ、及びＲＡＭ等の構成要素により構成されるマイクロコンピュータからなる。 On the control board 13, a switch 16 and a control unit 16 for processing signals from the biological information sensor 11 are mounted. The control unit 16 includes a microcomputer including components such as a CPU, a ROM, and a RAM.
制御部１６は、ＲＯＭに予め登録されている複数のテンプレートに基づいて押圧操作部２の押圧操作による操作指の生体情報を照合する機能を有するとともに、押圧操作部２の押圧操作を検出するスイッチ７から入力する信号に基づいて押圧操作部２の押圧操作の有無を認識する機能などを有している。 The control unit 16 has a function of collating the biological information of the operation finger by the pressing operation of the pressing operation unit 2 based on a plurality of templates registered in advance in the ROM, and a switch for detecting the pressing operation of the pressing operation unit 2. It has a function of recognizing the presence or absence of a pressing operation of the pressing operation unit 2 based on a signal input from the controller 7.
制御部１６は、車両電源から駆動電圧が供給されることにより、押圧操作部２による押圧操作の検出、及び生体情報センサ１１による生体情報の取得等が行える状態となる。なお、駆動電圧は、無線通信に基づく認証によるドアの開錠、メカニカルキーによるドアの開錠、あるいはドアの開放等によって供給される。 When the drive voltage is supplied from the vehicle power supply, the control unit 16 is in a state where the pressing operation by the pressing operation unit 2 can be detected and the biological information sensor 11 can acquire the biological information. The driving voltage is supplied by unlocking the door by authentication based on wireless communication, unlocking the door by a mechanical key, or opening the door.
押圧操作部２が押圧操作された際に、制御部１６は、押圧操作部２に設けられた生体情報センサ１１から操作指の生体情報を取得することで、取得した生体情報と、ＲＯＭに予め登録されている生体情報とを比較して照合する。生体情報を照合した結果は、制御基板１３に固定された外部接続用コネクタ１５の端子を介して図示しない車両側の制御部へ出力される。車両側の制御部では、生体情報の正否を確認する生体認証が実行される。 When the pressing operation unit 2 is pressed, the control unit 16 obtains the biological information of the operating finger from the biological information sensor 11 provided in the pressing operation unit 2, and stores the obtained biological information in the ROM in advance. The registered biometric information is compared and collated. The result of comparing the biometric information is output to a control unit (not shown) of the vehicle via a terminal of the external connection connector 15 fixed to the control board 13. In the control unit on the vehicle side, biometric authentication for confirming the validity of the biometric information is executed.
生体情報が一致すれば、生体認証を成立処理することで、押圧操作部２の押圧操作による車両の電源遷移操作が許可される。生体情報センサ１１により読み取られた生体情報がＲＯＭに予め登録されている生体情報と一致しない場合には、押圧操作部２の押圧操作による車両の電源遷移操作が許可されない。これにより、エンジンは始動しない。 If the biometric information matches, by performing the biometric authentication establishment process, the power transition operation of the vehicle by the pressing operation of the pressing operation unit 2 is permitted. If the biological information read by the biological information sensor 11 does not match the biological information registered in the ROM in advance, the power transition operation of the vehicle by the pressing operation of the pressing operation unit 2 is not permitted. As a result, the engine does not start.

Thereby, it becomes easy to connect the biological information sensor 11 via the flexible wiring 12 to the control board 13 to which the wiring connection connector 10, the sensor connection connector 14, and the external connection connector 15 are fixed.

制御基板１３に対する配線距離を短くすることができるため、ノイズの影響を受けることなく、生体情報センサ１１の検出動作の応答性を向上させることができる。 Since the wiring distance to the control board 13 can be shortened, the responsiveness of the detection operation of the biological information sensor 11 can be improved without being affected by noise.
制御基板１３に対する配線距離を短くすることができるため、配線の引き回しや組み付けが容易である。 Since the wiring distance to the control board 13 can be shortened, the wiring can be easily routed and assembled.
操作部ホルダ５には、押圧操作部２、スイッチ７、及び生体情報センサ１１が集約化されるとともに、制御基板１３の一端部にスイッチ７及び生体情報センサ１１の固定側の接続部が集約化されているため、スイッチ装置１の小型化や高密度実装化が可能となる。 In the operation unit holder 5, the pressing operation unit 2, the switch 7, and the biological information sensor 11 are integrated, and the connection part on the fixed side of the switch 7 and the biological information sensor 11 is integrated at one end of the control board 13.
