These adhesions may be realized by double-sided tape. The pillars 22 are provided at the four corners so as to correspond to the respective operation units 10 . A gap is provided between adjacent column portions 22 . As a result, the area of the operation panel 11 where the operation unit 10 is provided is bent while being supported by the pillars 22 at both ends.
　発光部１４は、操作パネル１１の一部を透過照明する。発光部１４は、インジケータレンズ１８、発光ダイオード（ＬＥＤ）１９および受電コイル２４を含んで構成される。受電コイル２４は、制御ユニットＵ２に設けられる給電コイル４３から非接触で送電される電力を受電する。受電コイル２４は、受電した電力をＬＥＤ１９に供給する。ＬＥＤ１９は、受電コイル２４から電力が供給されると発光する。インジケータレンズ１８は、一部が操作パネル１１に形成されている発光穴２５に挿入されている。インジケータレンズ１８は、透光性を有し、ＬＥＤ１９が発光した光を操作パネル１１の表面まで導く。 The light emitting unit 14 transmits and illuminates a part of the operation panel 11 .

The indicator lens 18 is inserted into a light emitting hole 25 partially formed in the operation panel 11 . The indicator lens 18 has translucency and guides the light emitted by the LED 19 to the surface of the operation panel 11 .
　識別用磁石Ｍ１は、操作ユニットＵ１を識別するために設けられる。操作ユニットＵ１は、制御ユニットＵ２に対して交換可能であり、操作ユニットＵ１毎に操作部１０の形状および配置などが異なる。そこで制御ユニットＵ２が操作ユニットＵ１の種類を識別するために、識別用磁石Ｍ１が用いられる。 The identification magnet M1 is provided to identify the operation unit U1. The operation unit U1 is replaceable with respect to the control unit U2, and the shape and arrangement of the operation section 10 differ for each operation unit U1. Therefore, the identification magnet M1 is used for the control unit U2 to identify the type of the operation unit U1.
　識別用磁石Ｍ１は、操作ユニットＵ１のうち予め設定された複数箇所の少なくとも１箇所に設けられている。図２～図５に示す例では、識別用磁石Ｍ１は底面カバー１２に取り付けられており、１つの識別用磁石Ｍ１が１箇所に設けられている。識別用磁石Ｍ１の表面は、制御ユニットＵ２の側に底面カバー１２から露出している。 The identification magnet M1 is provided in at least one of a plurality of preset locations in the operation unit U1. In the examples shown in FIGS. 2 to 5, the identification magnet M1 is attached to the bottom cover 12, and one identification magnet M1 is provided at one location. The surface of the identification magnet M1 is exposed from the bottom cover 12 on the side of the control unit U2.
　複数の操作部１０の数や配置、操作パネル１１の形状や大きさ、材質等、レイアウトの異なる複数種類の操作ユニットＵ１が予め準備されている。いずれの種類の操作ユニットＵ１においても、識別用磁石Ｍ１が設けられる平面位置は予め決められている。平面位置とは、操作パネル１１の操作面に対して平行な平面の位置のことである。ただし、識別用磁石Ｍ１が設けられる奥行位置は、操作ユニットＵ１の種類毎に異なっていてもよい。奥行位置とは、操作パネル１１の操作面に対して垂直な方向の位置のことである。 A plurality of types of operation units U1 with different layouts such as the number and arrangement of the plurality of operation units 10, the shape, size, and material of the operation panel 11 are prepared in advance. In any type of operation unit U1, the planar position where the identification magnet M1 is provided is determined in advance. A plane position is a plane position parallel to the operation surface of the operation panel 11 . However, the depth position where the identification magnet M1 is provided may differ for each type of the operation unit U1. A depth position is a position in a direction perpendicular to the operation surface of the operation panel 11 .
　そして、操作ユニットＵ１の種類毎に、識別用磁石Ｍ１の数と平面位置における配置が予め設定されている。換言すれば、識別用磁石Ｍ１によって形成される磁界のパターンが、操作ユニットＵ１の種類毎に異なるように設定されている。 Then, the number of identification magnets M1 and their arrangement on the plane are set in advance for each type of operation unit U1. In other words, the pattern of the magnetic field formed by the identification magnet M1 is set differently for each type of operation unit U1.
　次に、制御ユニットＵ２に関して説明する。制御ユニットＵ２は、液晶表示部４１、センサ用ＩＣ４４、センサコイル４５、駆動回路４６、給電コイル４３、ブザー４７、制御マイコン４８および複数のホールＩＣ６１～６３を含んで構成される。また制御ユニットＵ２は、基板カバー５１、制御基板５２およびケース５３を含んで構成される。 Next, the control unit U2 will be explained. The control unit U2 includes a liquid crystal display 41, a sensor IC 44, a sensor coil 45, a drive circuit 46, a feed coil 43, a buzzer 47, a control microcomputer 48, and a plurality of Hall ICs 61-63. Further, the control unit U2 includes a board cover 51, a control board 52 and a case 53. As shown in FIG.
　図３および図５に示すように、基板カバー５１は、制御ユニットＵ２の表側の表面を構成する部分である。基板カバー５１は、たとえば操作パネル１１に合わせた平板状の部材となっており、樹脂材から形成されている。またケース５３は、制御ユニットＵ２の裏側の表面を構成する部分である。ケース５３は、一面が開放された直方体状の容器状であって、樹脂材から形成されている。ケース５３の開放された一面は、基板カバー５１によって覆われる。ケース５３の内側の空間は、制御基板５２が収納される。また基板カバー５１の表面には、液晶表示部４１が配置される。制御基板５２には、集積回路であるセンサ用ＩＣ４４、センサコイル４５、駆動回路４６、給電コイル４３、ブザー４７および制御マイコン４８が実装されている。 As shown in FIGS. 3 and 5, the board cover 51 is a part that constitutes the front surface of the control unit U2. The substrate cover 51 is, for example, a plate-like member that fits the operation panel 11 and is made of a resin material. Further, the case 53 is a part that constitutes the back surface of the control unit U2. The case 53 is in the shape of a rectangular parallelepiped container with one side open, and is made of a resin material. One open surface of the case 53 is covered with the substrate cover 51 . A space inside the case 53 accommodates the control board 52 . A liquid crystal display section 41 is arranged on the surface of the substrate cover 51 . On the control board 52, a sensor IC 44, a sensor coil 45, a drive circuit 46, a feed coil 43, a buzzer 47, and a control microcomputer 48, which are integrated circuits, are mounted.
　液晶表示部４１は、表示画面の複数の領域に制御項目が割り当てられおり、車両用空調装置１１０に対する制御のために操作者の指Ｆなどのタッチによって操作される。液晶表示部４１は、液晶表示面の表側に透明電極部（図示せず）が設けられており、乗員のタッチ操作時の指Ｆとの間でコンデンサを形成するものとなっている。制御マイコン４８は、タッチ操作時のコンデンサによる静電容量の変化（静電容量値）をオン検出波形として処理する。液晶表示部４１をタッチ操作することで、たとえば温度設定および風量設定が選択できる。 The liquid crystal display unit 41 has control items assigned to a plurality of areas of the display screen, and is operated by touching with the operator's finger F or the like for controlling the vehicle air conditioner 110 . The liquid crystal display section 41 is provided with a transparent electrode section (not shown) on the front side of the liquid crystal display surface, and forms a capacitor with the finger F of the occupant during touch operation. The control microcomputer 48 processes the change in capacitance (capacitance value) caused by the capacitor at the time of touch operation as an ON detection waveform. By performing a touch operation on the liquid crystal display section 41, for example, temperature setting and air volume setting can be selected.
　センサコイル４５とセンサ用ＩＣ４４は、操作部１０が押圧操作されたときの操作パネル１１の変位を操作パネル１１とは非接触で検出する。したがってセンサコイル４５とセンサ用ＩＣ４４は、検出部５０として機能する。センサコイル４５は、電力を供給することで電磁界を発生するコイルである。センサ用ＩＣ４４は、センサコイル４５に接続され、操作パネル１１の突起部１６の導体１５の変位をセンサコイル４５のインダクタンスの変化によって検出する。したがってセンサ用ＩＣ４４とセンサコイル４５は、導体１５の位置を検出する誘導型近接センサである。センサ用ＩＣ４４は、インダクタンス値を制御マイコン４８に出力する。制御マイコン４８は、インダクタンス値の変化をオン検出波形として処理する。 The sensor coil 45 and sensor IC 44 detect the displacement of the operation panel 11 when the operation unit 10 is pressed without contacting the operation panel 11 . Therefore, the sensor coil 45 and the sensor IC 44 function as the detection section 50 . The sensor coil 45 is a coil that generates an electromagnetic field by supplying power. The sensor IC 44 is connected to the sensor coil 45 and detects displacement of the conductor 15 of the protrusion 16 of the operation panel 11 by a change in inductance of the sensor coil 45 . Therefore, the sensor IC 44 and the sensor coil 45 are inductive proximity sensors that detect the position of the conductor 15 . The sensor IC 44 outputs the inductance value to the control microcomputer 48 . The control microcomputer 48 processes the change in inductance value as an ON detection waveform.
　駆動回路４６は、給電コイル４３およびブザー４７に駆動信号を送る回路である。駆動回路４６は、制御マイコン４８によって制御される。駆動回路４６によって給電コイル４３がＯＮになると、給電コイル４３は受電コイル２４に送電する。給電コイル４３は、ＯＮになると通電されて、非接触で受電コイル２４に送電するために受電コイル２４と磁界共鳴によって磁気的に結合する。これによって給電コイル４３から受電コイル２４に非接触で給電される。したがって給電コイル４３は、給電部として機能する。 The drive circuit 46 is a circuit that sends drive signals to the feed coil 43 and the buzzer 47 . The drive circuit 46 is controlled by a control microcomputer 48 . When the power supply coil 43 is turned on by the drive circuit 46 , the power supply coil 43 transmits power to the power reception coil 24 . The power supply coil 43 is energized when it is turned on, and is magnetically coupled to the power reception coil 24 by magnetic field resonance in order to transmit power to the power reception coil 24 in a non-contact manner. Thereby, power is supplied from the power feeding coil 43 to the power receiving coil 24 in a non-contact manner. Therefore, the feeding coil 43 functions as a feeding section.
　ブザー４７は、音を出力する音出力部である。ブザー４７は、駆動回路４６によってＯＮになると、音を出力する。これによって操作者は、音によって操作したことを認識できる。 The buzzer 47 is a sound output unit that outputs sound. The buzzer 47 outputs sound when turned on by the drive circuit 46 . This allows the operator to recognize the operation by the sound.
　制御マイコン４８は、制御部であって、記憶媒体に記憶されているプログラムを実行し、各部を制御する。制御マイコン４８は、少なくとも１つの演算処理装置（ＣＰＵ）と、プログラムとデータとを記憶する記憶媒体とを有する。制御マイコン４８は、たとえばコンピュータによって読み取り可能な記憶媒体を備えるマイクロコンピュータによって実現される。記憶媒体は、コンピュータによって読み取り可能なプログラムおよびデータを非一時的に格納する非遷移的実体的記憶媒体である。記憶媒体は、半導体メモリまたは磁気ディスクなどによって実現される。 The control microcomputer 48 is a control unit, executes a program stored in a storage medium, and controls each unit. The control microcomputer 48 has at least one arithmetic processing unit (CPU) and a storage medium for storing programs and data. The control microcomputer 48 is implemented by, for example, a microcomputer having a computer-readable storage medium. The storage medium is a non-transitional tangible storage medium that non-temporarily stores computer-readable programs and data. A storage medium is realized by a semiconductor memory, a magnetic disk, or the like.
　具体的には、制御マイコン４８は、液晶表示部４１およびセンサ用ＩＣ４４から得られる検出値に基づいて、操作に対応した制御信号を生成し、車両用空調装置１１０へ有線で出力するようになっている。これによって車両用空調装置１１０が制御される。 Specifically, the control microcomputer 48 generates a control signal corresponding to the operation based on the detection values obtained from the liquid crystal display unit 41 and the sensor IC 44, and outputs the control signal to the vehicle air conditioner 110 by wire. ing. The vehicle air conditioner 110 is thereby controlled.
　ホールＩＣ６１～６３は、磁界の大きさを検出する素子であり、制御基板５２に実装されている。ホールＩＣ６１～６３は、制御ユニットＵ２のうち予め設定された複数箇所に設けられている。図２～図５に示す例では、ホールＩＣ６１～６３は、制御基板５２の３箇所に設けられている。ホールＩＣ６１～６３は、基板カバー５１によって覆われて保護されている。ホールＩＣ６１～６３の配置は、識別用磁石Ｍ１に対向するように、所定方向（上下方向）に１列に並ぶ３箇所に設定されている。 The Hall ICs 61 to 63 are elements that detect the magnitude of the magnetic field and are mounted on the control board 52 . The Hall ICs 61 to 63 are provided at a plurality of preset locations in the control unit U2. In the examples shown in FIGS. 2 to 5, the Hall ICs 61 to 63 are provided at three locations on the control board 52. FIG. The Hall ICs 61 to 63 are covered and protected by a substrate cover 51 . The Hall ICs 61 to 63 are arranged in three locations in a row in a predetermined direction (vertical direction) so as to face the identification magnet M1.
　換言すれば、識別用磁石Ｍ１によって形成される磁界のパターンが、ホールＩＣ６１～６３によって検出される。したがって、ホールＩＣ６１～６３は、制御ユニットＵ２に取り付けられている操作ユニットＵ１のレイアウトが複数種類のいずれであるかを識別するセンサとして機能する。 In other words, the magnetic field pattern formed by the identification magnet M1 is detected by the Hall ICs 61-63. Therefore, the Hall ICs 61 to 63 function as sensors for identifying which of a plurality of types the layout of the operation unit U1 attached to the control unit U2 is.
　先述した通り、操作ユニットＵ１の種類によって操作部１０の数や配置が異なる。これに対し制御ユニットＵ２は、取り付けられている操作ユニットＵ１の種類に拘わらず共通化されている。そのため、取り付けられている操作ユニットＵ１の種類によっては、複数のセンサコイル４５のうち、使用されていないセンサコイル４５が存在する場合がある。 As mentioned above, the number and arrangement of the operation units 10 differ depending on the type of the operation unit U1. On the other hand, the control unit U2 is common regardless of the type of the attached operation unit U1. Therefore, depending on the type of operation unit U1 attached, there may be sensor coils 45 that are not used among the plurality of sensor coils 45 .
　また、操作ユニットＵ１の種類によって、液晶表示部４１に対する貫通穴２０の形状や位置が異なる。これに対し制御ユニットＵ２は共通化されており、取り付けられている操作ユニットＵ１の種類によっては、液晶表示部４１のうち視認されない表示部が存在する場合がある。 Also, the shape and position of the through hole 20 with respect to the liquid crystal display section 41 differ depending on the type of the operation unit U1. On the other hand, the control unit U2 is shared, and depending on the type of the attached operation unit U1, there may be a display part that is not visually recognized in the liquid crystal display part 41 .
　次に、具体的な検出部５０の検出方法に関して説明する。押下式の操作部１０は、図３に示すように指Ｆによって押下操作されると、下方に湾曲するように弾性変形する。これによって突起部１６の先端とセンサコイル４５との距離は、押下前に比べて、たとえば数十μｍ小さくなる。突起部１６の先端には導体１５があるので、導体１５とセンサコイル４５との距離が小さくなる。これによって前述したようにセンサコイル４５のインダクタンスが変化するので、センサ用ＩＣ４４によって押圧操作が非接触で検出される。 Next, a specific detection method of the detection unit 50 will be described. The push-down type operation unit 10 is elastically deformed so as to curve downward when pushed by a finger F as shown in FIG. As a result, the distance between the tip of the protrusion 16 and the sensor coil 45 is reduced by, for example, several tens of μm compared to before the depression. Since the conductor 15 is located at the tip of the protrusion 16, the distance between the conductor 15 and the sensor coil 45 is reduced. As a result, the inductance of the sensor coil 45 changes as described above, so that the sensor IC 44 detects the pressing operation without contact.
　なお、柱部２２は、近接する操作部１０の押下領域が変形することを抑制するように機能している。柱部２２がない構成であると、近接する部分まで全体として大きく撓んでしまし、隣り合うスイッチが誤検出される懸念があるからである。 It should be noted that the column portion 22 functions to suppress deformation of the pressing area of the adjacent operation portion 10 . This is because if the structure does not have the column 22, even the adjacent parts will be greatly bent as a whole, and there is a concern that the adjacent switches may be erroneously detected.
　ダイヤル式の操作部１０が回転操作されると、操作部１０に設けられた複数の導体１５がセンサコイル４５に近づいたり離れたりを交互に繰り返すことになる。その結果、センサコイル４５のインダクタンスは、増大と減少を繰り返すように変化する。制御マイコン４８は、このようなインダクタンス変化の繰り返し回数をカウントすることで、操作部１０の回転操作量を、操作部１０とは非接触で検出する。 When the dial-type operation unit 10 is rotated, the plurality of conductors 15 provided on the operation unit 10 alternately move toward and away from the sensor coil 45 . As a result, the inductance of the sensor coil 45 changes so as to repeatedly increase and decrease. The control microcomputer 48 counts the number of repetitions of such inductance changes, thereby detecting the rotational operation amount of the operation unit 10 without contact with the operation unit 10 .
　次に、取り付けられている操作ユニットＵ１の種類を制御マイコン４８が識別する、具体的な識別方法に関して説明する。制御マイコン４８は、ホールＩＣ６１～６３で検知された磁界の大きさが閾値以上である場合に、該当するホールＩＣ６１～６３の箇所に識別用磁石Ｍ１が存在しているとみなす。そして複数のホールＩＣ６１～６３による検知結果の組み合わせで、制御マイコン４８は識別情報を取得する。 Next, a specific identification method by which the control microcomputer 48 identifies the type of the attached operation unit U1 will be described. When the magnitude of the magnetic field detected by the Hall ICs 61-63 is equal to or greater than the threshold value, the control microcomputer 48 determines that the identification magnet M1 exists at the corresponding Hall ICs 61-63. The control microcomputer 48 obtains identification information from a combination of detection results from the plurality of Hall ICs 61-63.
　次に、制御マイコン４８が液晶表示部４１、給電コイル４３、車両用空調装置１１０を制御するにあたり、その制御内容について説明する。制御マイコン４８は、識別情報を取得した後に、識別情報に応じた内容で液晶表示部４１を起動させる。換言すれば、識別情報を取得するまでは、液晶表示部４１の起動は待機される。例えば未使用表示部が存在する場合と、未使用表示部が存在しない場合とで、液晶表示部４１の表示内容は異なる。また操作部１０の数や、操作部１０に割り付けられた機能に応じて、液晶表示部４１の表示内容は異なる。 Next, when the control microcomputer 48 controls the liquid crystal display unit 41, the feed coil 43, and the vehicle air conditioner 110, the details of the control will be described. After acquiring the identification information, the control microcomputer 48 activates the liquid crystal display section 41 with the content corresponding to the identification information. In other words, the activation of the liquid crystal display unit 41 is put on standby until the identification information is acquired. For example, the display contents of the liquid crystal display section 41 differ depending on whether there is an unused display section or when there is no unused display section. Further, the display contents of the liquid crystal display section 41 differ depending on the number of the operation sections 10 and the functions assigned to the operation sections 10 .
　制御マイコン４８は、識別情報を取得した後に、センサ用ＩＣ４４で操作が検知されると、その検知内容、つまり車両乗員による操作内容に応じて制御信号を出力する。制御信号の出力対象（制御対象）は、液晶表示部４１、給電コイル４３および車両用空調装置１１０である。 After acquiring the identification information, when the sensor IC 44 detects an operation, the control microcomputer 48 outputs a control signal according to the content of the detection, that is, the content of the operation by the vehicle occupant. Targets to which the control signal is output (targets to be controlled) are the liquid crystal display section 41 , the feed coil 43 and the vehicle air conditioner 110 .
　例えば、複数の操作部１０のうちオートモードに関連付けられた操作部１０への操作が検知されると、制御マイコン４８は、その操作部１０に対応する給電コイル４３を作動させて、オートモードに係る操作部１０のＬＥＤ１９を点灯させる。加えて、オートモードで作動させる制御信号を、制御マイコン４８は車両用空調装置１１０へ出力する。加えて、オートモードで作動させる旨を液晶表示部４１に表示させる制御信号を、制御マイコン４８は液晶表示部４１へ出力する。 For example, when an operation to the operation unit 10 associated with the automatic mode is detected among the plurality of operation units 10, the control microcomputer 48 activates the feeding coil 43 corresponding to the operation unit 10 to switch to the automatic mode. The LED 19 of the operation unit 10 is turned on. In addition, the control microcomputer 48 outputs a control signal for operating in the auto mode to the vehicle air conditioner 110 . In addition, the control microcomputer 48 outputs to the liquid crystal display section 41 a control signal for causing the liquid crystal display section 41 to display that the automatic mode is to be operated.
　次に、操作ユニットＵ１と制御ユニットＵ２の着脱可能な構成に関して説明する。操作ユニットＵ１と制御ユニットＵ２とは、図３および図４に示すように、電気的に接触して信号を互いに送受信する部分を有していない。換言すると、底面カバー１２と基板カバー５１とが接触して固定されるが、電気的に接触する部分は有していない。そして操作ユニットＵ１は、前述のように制御ユニットＵ２と分離することができる。操作ユニットＵ１の着脱作業は、たとえば車両メーカ、ディーラーおよびユーザなど、誰でも実施できる方が好ましい。特にユーザが取り替える場面を考えると、安全性も考慮して、誤操作なく簡単に扱えるような着脱機構が好ましい。 Next, the detachable configuration of the operation unit U1 and the control unit U2 will be described. As shown in FIGS. 3 and 4, the operation unit U1 and the control unit U2 do not have a portion that makes electrical contact and transmits and receives signals to and from each other. In other words, the bottom cover 12 and the board cover 51 are fixed in contact with each other, but do not have a portion that makes electrical contact. The operating unit U1 can then be separated from the control unit U2 as described above. It is preferable that anyone, such as a vehicle manufacturer, a dealer, or a user, can perform the attachment/detachment work of the operation unit U1. In particular, considering the situation where the user replaces the device, it is preferable to use an attachment/detachment mechanism that can be easily handled without an erroneous operation in consideration of safety.
　本実施形態の着脱機構は、操作ユニットＵ１を制御ユニットＵ２に固定する固定状態と、操作ユニットＵ１を制御ユニットＵ２の固定状態を解除した解除状態とを切り替えることができる機構を有する。そして操作ユニットＵ１を制御ユニットＵ２に固定した固定状態では、走行による振動によって制御ユニットＵ２から操作ユニットＵ１がずれたり、脱落したりすることないよう固定されている。さらに固定状態では、ユーザが誤って操作ユニットＵ１を外そうとしても、脱落したり、操作ユニットＵ１の位置がずれたりすることがないように固定されている。 The attachment/detachment mechanism of this embodiment has a mechanism capable of switching between a fixed state in which the operation unit U1 is fixed to the control unit U2 and a release state in which the operation unit U1 is released from the fixed state of the control unit U2. In the fixed state where the operation unit U1 is fixed to the control unit U2, the operation unit U1 is fixed so as not to shift or come off from the control unit U2 due to vibrations caused by traveling. Furthermore, in the fixed state, even if the user tries to detach the operation unit U1 by mistake, it is fixed so as not to fall off or shift the position of the operation unit U1.
　また固定状態を解除した解除状態では、操作ユニットＵ１が制御ユニットＵ２から落下することはないが、ユーザの操作力によって操作ユニットＵ１が制御ユニットＵ２から簡単に外れる状態となる。 In addition, in the released state where the fixed state is released, the operation unit U1 does not drop from the control unit U2, but the operation unit U1 is easily detached from the control unit U2 by the user's operation force.
　このような機構によって、操作ユニットＵ１を取り外す場合、（１）操作ユニットＵ１が制御ユニットＵ２に固定された固定状態から、（２）操作ユニットＵ１が取り替えられる解除状態にして、（３）ユーザが操作ユニットＵ１を取り外す操作力を加えて、（４）操作ユニットＵ１が外れることになる。 When the operation unit U1 is removed by such a mechanism, (1) the operation unit U1 is changed from a fixed state in which the operation unit U1 is fixed to the control unit U2 to (2) a released state in which the operation unit U1 is replaced, and (3) the user By applying an operation force to remove the operation unit U1, (4) the operation unit U1 is removed.
　次に、着脱機構の具体的な構成に関して説明する。本実施形態の着脱機構は、電磁石の原理に着目し、電磁石による磁力を利用した着脱機構である。具体的には、通電の有無で励磁する固定用電磁石６８を用いて、固定状態にするときに固定用電磁石６８に電気を流す。これによって固定用電磁石６８の磁力によって、操作ユニットＵ１が制御ユニットＵ２に固定される。 Next, the specific configuration of the attachment/detachment mechanism will be described. The attachment/detachment mechanism of the present embodiment is an attachment/detachment mechanism that focuses on the principle of an electromagnet and utilizes the magnetic force of the electromagnet. Specifically, a fixing electromagnet 68 that is excited by the presence or absence of energization is used, and electricity is applied to the fixing electromagnet 68 when the fixing state is established. As a result, the magnetic force of the fixing electromagnet 68 fixes the operation unit U1 to the control unit U2.
　また解除状態では、操作ユニットＵ１と制御ユニットＵ２とを分離可能な仮固定状態と、図４に示すように完全に分離した分離状態とを含む。仮固定状態とは、操作ユニットＵ１は制御ユニットＵ２に固定されてはいるが、固定状態よりも固定力が弱く、ユーザの操作力によって分離できる状態である。換言すると、固定状態では、ユーザの操作力によって分離できない状態である。仮固定状態では、操作ユニットＵ１は制御ユニットＵ２に弱い磁力で固定されており、制御ユニットＵ２から落下しないような状態にある。本実施形態では、永久磁石の磁力によって仮固定状態を実現している。したがって固定状態では電磁石の磁力を利用した固定であり、仮固定状態では永久磁石の磁力を利用した固定であるので、固定状態で固定する構成と仮固定状態にて固定する構成とは異なる。 The released state includes a temporarily fixed state in which the operation unit U1 and the control unit U2 can be separated, and a separated state in which the operation unit U1 and the control unit U2 are completely separated as shown in FIG. The temporarily fixed state is a state in which although the operation unit U1 is fixed to the control unit U2, the fixing force is weaker than that in the fixed state, and can be separated by the user's operation force. In other words, in the fixed state, it cannot be separated by the user's operation force. In the temporarily fixed state, the operation unit U1 is fixed to the control unit U2 with a weak magnetic force, and is in a state where it will not fall from the control unit U2. In this embodiment, the temporarily fixed state is realized by the magnetic force of the permanent magnet. Therefore, the fixed state is fixed using the magnetic force of the electromagnet, and the temporary fixed state is fixed using the magnetic force of the permanent magnet.
　まず、仮固定状態の構成に関して説明する。操作ユニットＵ１の底面カバー１２の表側には、図３および図７に示すように、第１磁石１７が設けられている。また基板カバー５１の裏側には、第２磁石４２が設けられている。第１磁石１７および第２磁石４２は、永久磁石であって、図３に示す配置状態にて、磁力によって引き合うように磁極が設定されている。また第１磁石１７と第２磁石４２とは、配置状態で近接するように配置されている。これにより、操作ユニットＵ１は、第１磁石１７と第２磁石４２との磁力によって、制御ユニットＵ２に仮固定状態となる。仮固定状態では、第１磁石１７と第２磁石４２との磁力によって、操作ユニットＵ１が制御ユニットＵ２から落ちないようになっている。そして仮固定状態では、第１磁石１７と第２磁石４２との磁力よりも大きい操作力を加えることで、完全に分離することができる。 First, the configuration of the temporarily fixed state will be explained. As shown in FIGS. 3 and 7, a first magnet 17 is provided on the front side of the bottom cover 12 of the operation unit U1. A second magnet 42 is provided on the back side of the board cover 51 . The first magnet 17 and the second magnet 42 are permanent magnets, and their magnetic poles are set so that they are attracted to each other by magnetic force in the arrangement state shown in FIG. Also, the first magnet 17 and the second magnet 42 are arranged so as to be close to each other. As a result, the operation unit U1 is temporarily fixed to the control unit U2 by the magnetic force of the first magnet 17 and the second magnet 42. As shown in FIG. In the temporarily fixed state, the magnetic force of the first magnet 17 and the second magnet 42 prevents the operation unit U1 from falling off the control unit U2. In the temporarily fixed state, by applying an operating force greater than the magnetic force between the first magnet 17 and the second magnet 42, they can be completely separated.
　次に、固定状態の構成に関して説明する。制御ユニットＵ２は、図７に示すように、さらに固定駆動部６４を備える。固定駆動部６４は、制御ユニットＵ２の表面のうち、操作ユニットＵ１に対向する部分に設けられる。固定駆動部６４は、操作ユニットＵ１に係合し操作ユニットＵ１を制御ユニットＵ２に固定する固定状態と、固定状態による固定を解除する解除状態とを切り替える。固定駆動部６４は、本実施形態では固定用電磁石６８および固定用電磁石６８を駆動する電源回路６５によって実現される。電源回路６５は、固定用電磁石６８に電流を供給する状態と、電流を停止する状態とを切り替える。そして固定用電磁石６８は、通電されることで励磁する。 Next, the configuration of the fixed state will be explained. The control unit U2 further comprises a fixed drive 64, as shown in FIG. The fixed driving portion 64 is provided on a portion of the surface of the control unit U2 that faces the operation unit U1. The fixing drive section 64 switches between a fixed state in which the operation unit U1 is engaged with the operation unit U1 and fixed to the control unit U2, and a release state in which the fixed state is released. The fixed driving section 64 is implemented by a fixing electromagnet 68 and a power supply circuit 65 that drives the fixing electromagnet 68 in this embodiment. The power supply circuit 65 switches between a state of supplying current to the fixing electromagnet 68 and a state of stopping the current. The fixing electromagnet 68 is excited by being energized.
　また操作ユニットＵ１には、図７に示すように、固定用磁石６６が設けられている。固定用電磁石６８と固定用磁石６６とは、図７に示す配置状態では近接するように配置されている。固定用磁石６６は、永久磁石であって、配置状態で励磁した固定用電磁石６８と磁力によって引き合うように磁極が設定されている。固定用磁石６６は、永久磁石でなく、強磁性体でもよい。 Also, the operation unit U1 is provided with a fixing magnet 66 as shown in FIG. The fixing electromagnet 68 and the fixing magnet 66 are arranged so as to be close to each other in the arrangement state shown in FIG. The fixing magnet 66 is a permanent magnet, and the magnetic pole is set so as to attract the fixing electromagnet 68 excited in the arranged state by magnetic force. The fixing magnet 66 may be a ferromagnetic material instead of a permanent magnet.
　図７のように、制御マイコン４８および固定用電磁石６８には、電源回路６５を介してＩＧ電源１２０から電力が供給される。ＩＧ電源１２０は、イグニッションがオンになると電源回路６５に電力を供給し、イグニッションがオフになると電源回路６５への電力供給を停止する。電源回路６５は、ＩＧ電源１２０から電力が供給されると、制御マイコン４８および固定用電磁石６８に、それぞれに応じた電力を供給する。固定用電磁石６８は、電源回路６５から電力が供給されると、通電されて励磁状態となる。また制御マイコン４８は、電源回路６５から電力が供給されると起動状態となり、所定の制御を実施可能となる。 As shown in FIG. 7, power is supplied from the IG power supply 120 to the control microcomputer 48 and the fixing electromagnet 68 through the power supply circuit 65 . The IG power supply 120 supplies power to the power supply circuit 65 when the ignition is turned on, and stops supplying power to the power supply circuit 65 when the ignition is turned off. When power is supplied from IG power supply 120 , power supply circuit 65 supplies corresponding power to control microcomputer 48 and fixing electromagnet 68 . When power is supplied from the power supply circuit 65, the fixing electromagnet 68 is energized and placed in an excited state. Further, the control microcomputer 48 is activated when power is supplied from the power supply circuit 65, and can perform predetermined control.
　したがって図７に示すように、イグニッションがオフの仮固定状態から、イグニッションがオンになると、固定用電磁石６８が励磁し、固定用磁石６６との引力によって操作ユニットＵ１は固定状態となる。これによってユーザは取り外すことができない。換言すると、ＩＧ電源１２０がＯＮの状態で、操作ユニットＵ１の取り替えはできない。走行中、または走行可能な状態での取り替えは好ましくないからである。そしてイグニッションがオフになると、ＩＧ電源１２０がＯＦＦになり、電源回路６５から固定用電磁石６８への電力供給が停止する。電力供給の停止により、固定用電磁石６８の吸引力がなくなり、仮固定状態になる。 Therefore, as shown in FIG. 7, when the ignition is turned on from the temporarily fixed state in which the ignition is off, the fixing electromagnet 68 is excited, and the operation unit U1 is fixed by the attractive force with the fixing magnet 66. This prevents the user from removing it. In other words, the operation unit U1 cannot be replaced while the IG power supply 120 is ON. This is because it is not preferable to replace the tire while it is running or in a state where it can be run. When the ignition is turned off, the IG power supply 120 is turned off, and power supply from the power supply circuit 65 to the fixing electromagnet 68 is stopped. When the power supply is stopped, the attraction force of the fixing electromagnet 68 is lost and the temporarily fixed state is established.
　仮固定状態において、操作ユニットＵ１を取り外す際は、たとえば指Ｆを引っかけられる切欠き形状６７に指Ｆをかけ、手前に引いて取り外す。切欠き形状６７は、本実施形態では操作ユニットＵ１の上部に設けられる。切欠き形状６７は、あってもなくてもよく、手前に引き出す操作力を操作ユニットＵ１に付与できれ形状があればよい。 In the temporarily fixed state, when removing the operation unit U1, put the finger F on the notch shape 67 where the finger F can be hooked, for example, and pull it forward to remove it. The notch shape 67 is provided in the upper part of the operation unit U1 in this embodiment. The notch shape 67 may or may not be present, and it is sufficient if it has a shape capable of imparting an operating force to the operation unit U1 to pull it forward.
　また分離状態から操作ユニットＵ１を取り付ける際は、第１磁石１７および第２磁石４２が対向する設置位置へ操作ユニットＵ１を配置する。これによって第１磁石１７および第２磁石４２の磁力によって仮固定状態となる。 Also, when attaching the operation unit U1 from the separated state, the operation unit U1 is arranged at the installation position where the first magnet 17 and the second magnet 42 face each other. As a result, the magnetic force of the first magnet 17 and the second magnet 42 results in a temporarily fixed state.
　以上説明したように本実施形態の車両用操作装置１００では、操作ユニットＵ１と制御ユニットＵ２が係合し、第１磁石１７および第２磁石４２によって、操作ユニットＵ１と制御ユニットＵ２とは位置合わせがされる。そして固定駆動部６４は、操作ユニットＵ１および制御ユニットＵ２の固定状態と解除状態とを切り替える。固定駆動部６４は、操作ユニットＵ１に対向する部分に設けられるので、操作パネル１１の表面に脱着のための専用のスペースが不要である。したがって操作ユニットＵ１の表面を操作領域のために有効に活用することができる。 As described above, in the vehicle operation device 100 of the present embodiment, the operation unit U1 and the control unit U2 are engaged, and the first magnet 17 and the second magnet 42 align the operation unit U1 and the control unit U2. is done. The fixed driving section 64 switches between the fixed state and the released state of the operation unit U1 and the control unit U2. Since the fixed driving portion 64 is provided in a portion facing the operation unit U1, a dedicated space for attachment and detachment is not required on the surface of the operation panel 11. FIG. Therefore, the surface of the operation unit U1 can be effectively utilized for the operation area.
　また本実施形態では、第１磁石１７および第２磁石４２の磁力によって、操作ユニットＵ１が制御ユニットＵ２に取り付けられている。そのため、制御ユニットＵ２の仮固定状態への取り付け作業性を向上できる。加えて、制御ユニットＵ２から操作ユニットＵ１を取り外して別の操作ユニットＵ１に付け替える作業性についても向上できる。 Further, in this embodiment, the operation unit U1 is attached to the control unit U2 by the magnetic force of the first magnet 17 and the second magnet 42. Therefore, the workability of attaching the control unit U2 to the temporarily fixed state can be improved. In addition, the workability of removing the operation unit U1 from the control unit U2 and replacing it with another operation unit U1 can be improved.
　また本実施形態では、通電によって固定用電磁石６８が磁力を発した状態では、固定用磁石６６と引き合うことで固定状態となり、固定用電磁石６８への通電を停止した状態では解除状態となる。固定用電磁石６８の通電状態を制御することで、固定状態と解除状態とを切り替えることができる。 In addition, in this embodiment, when the fixing electromagnet 68 emits a magnetic force due to energization, it is in a fixed state by being attracted to the fixing magnet 66, and in a state when the fixing electromagnet 68 is de-energized, it is in a released state. By controlling the energized state of the fixing electromagnet 68, it is possible to switch between the fixed state and the released state.
　さらに本実施形態では、制御マイコン４８は、イグニッションがオンの場合には固定状態となるように制御し、イグニッションがオフの場合には解除状態となるように制御する。イグニッションのオンオフと連動して、固定状態と解除状態とが切り替えられ、イグニッションがオンの場合には固定状態となる。これによってイグニッションがオンのときに操作ユニットＵ１を取外すことを禁止することができる。またイグニッションのオンオフで固定用電磁石６８が駆動するので、固定用電磁石６８を駆動するための専用のボタンなどが不要である。 Furthermore, in the present embodiment, the control microcomputer 48 controls to be in a fixed state when the ignition is on, and controls to be in a released state when the ignition is off. The fixed state and the released state are switched in conjunction with turning on/off the ignition, and when the ignition is turned on, the fixed state is established. This makes it possible to prohibit removal of the operation unit U1 when the ignition is on. Further, since the fixing electromagnet 68 is driven by turning the ignition on and off, a dedicated button or the like for driving the fixing electromagnet 68 is not required.
　さらに本実施形態では、制御ユニットＵ２は、操作部１０とは非接触で操作内容を操作部１０から検知するものである。非接触で操作内容を検知するので、操作ユニットＵ１と制御ユニットＵ２との機械的結合による操作パネル１１のレイアウト自由度低下を、抑制できる。 Furthermore, in this embodiment, the control unit U2 detects the operation content from the operation unit 10 without contacting the operation unit 10. Since the content of the operation is detected without contact, it is possible to suppress a decrease in the degree of freedom in layout of the operation panel 11 due to mechanical coupling between the operation unit U1 and the control unit U2.
　（第２実施形態）
　次に、本開示の第２実施形態に関して、図８および図９を用いて説明する。本実施形態では、前述の第１実施形態と固定用磁石６６の位置が異なり、さらに仮固定状態にする構成に特徴を有する。 (Second embodiment)
Next, a second embodiment of the present disclosure will be described using FIGS. 8 and 9. FIG. This embodiment differs from the above-described first embodiment in the position of the fixing magnet 66, and is further characterized by the provisionally fixed state.
　図８および図９に示すように、操作ユニットＵ１の操作パネル１１Ａは、断面形状がＣ字状に形成されている。断面形状は、図８に示すように、上下方向に延びる本体部７１と、本体部７１の上下方向の両端部から左側へ延びる壁部７２とを有し、本体部７１と２つの壁部７２との全体で断面Ｃ字状を構成している。そして２つの壁部７２は、固定状態において制御ユニットＵ２に対向する対向面を有する。 As shown in FIGS. 8 and 9, the operation panel 11A of the operation unit U1 has a C-shaped cross section. As shown in FIG. 8, the cross-sectional shape includes a body portion 71 extending in the vertical direction and wall portions 72 extending leftward from both ends of the body portion 71 in the vertical direction. and form a C-shaped cross section. The two walls 72 have opposing surfaces facing the control unit U2 in the fixed state.
　また上側の壁部７２の対向面には、仮固定状態にするための凹部７３が設けられ、下側の壁部７２には固定用磁石６６が設けられている。制御ユニットＵ２の凹部７３に対向する部分には、ボールプランジャ７４が設けられ、ボールプランジャ７４のボール７５が凹部７３に嵌合する。ボールプランジャ７４は、ボール７５を外側に付勢するばね７６を内蔵し、先端のボール７５が外からの荷重によって変位する。ボールプランジャ７４のボール７５は、荷重が作用していない無負荷状態では基準位置にあり、荷重が作用すると基端側に変位する。これによって図９に示す分離状態から、操作ユニットＵ１を左側へ変位させて、壁部７２がボール７５を下側に押圧することで、図８の仮固定状態にすることができる。またボール７５が凹部７３に嵌合することで、制御ユニットＵ２と操作ユニットＵ１とを位置決めすることができる。 A concave portion 73 is provided on the facing surface of the upper wall portion 72 for temporary fixing, and a fixing magnet 66 is provided on the lower wall portion 72 . A ball plunger 74 is provided in a portion facing the recess 73 of the control unit U2, and a ball 75 of the ball plunger 74 fits into the recess 73. As shown in FIG. The ball plunger 74 incorporates a spring 76 that biases the ball 75 outward, and the ball 75 at the tip is displaced by an external load. The ball 75 of the ball plunger 74 is at the reference position in a non-loaded state, and is displaced toward the proximal end when a load is applied. As a result, the operation unit U1 is displaced leftward from the separated state shown in FIG. 9, and the wall portion 72 presses the ball 75 downward, whereby the temporarily fixed state shown in FIG. 8 can be obtained. Further, by fitting the ball 75 into the concave portion 73, the control unit U2 and the operation unit U1 can be positioned.
　また仮固定状態から、操作ユニットＵ１を右側へ変位させると、その操作力によって先端のボール７５を下側に押圧することで、再び分離状態にすることができる。換言すると、ボール７５を下側に押圧する操作力が必要であるので、仮固定状態であっても、簡単に脱落することを防ぐことができる。 Further, when the operation unit U1 is displaced to the right side from the temporarily fixed state, the operation force presses the ball 75 at the tip downward, so that the separated state can be restored. In other words, since an operation force is required to press the ball 75 downward, it is possible to prevent the ball 75 from falling off easily even in the temporarily fixed state.
　そして仮固定状態で、イグニッションをオンにすることで、固定用電磁石６８の磁力によって、下側の壁部７２の固定用磁石６６が吸引されて、固定状態となる。このように固定状態では、操作ユニットＵ１の壁部７２と本体部７１とが制御ユニットＵ２に係合する係合部となる。これによって操作ユニットＵ１を取り付ける際は、制御ユニットＵ２側へ押し込み、取り外す際は、切欠き形状６７に指Ｆをかけ、手前に引いて取り外すことができる。 Then, by turning on the ignition in the temporarily fixed state, the fixing magnet 66 on the lower wall portion 72 is attracted by the magnetic force of the fixing electromagnet 68, resulting in a fixed state. In this fixed state, the wall portion 72 and the main body portion 71 of the operation unit U1 serve as an engaging portion that engages with the control unit U2. As a result, when the operation unit U1 is attached, it can be pushed toward the control unit U2 side, and when it is removed, it can be removed by putting a finger F on the notch shape 67 and pulling it toward you.
　このように本実施形態では、仮固定状態が磁力を用いず、ボールプランジャ７４を用いて機械的構成によって係合している。このような構成であっても、仮固定状態を実現することができる。またボールプランジャ７４の構成にかぎらず、スナップフィットなど他の機械的構成であってもよい。 As described above, in this embodiment, the temporarily fixed state is engaged by a mechanical configuration using the ball plunger 74 without using a magnetic force. Even with such a configuration, the temporarily fixed state can be realized. Further, the configuration of the ball plunger 74 is not limited, and other mechanical configurations such as a snap fit may be used.
　（第３実施形態）
　次に、本開示の第３実施形態に関して、図１０および図１１を用いて説明する。本実施形態では、固定用電磁石６８を用いずに、変位部８１を有する点に特徴を有する。 (Third Embodiment)
Next, a third embodiment of the present disclosure will be described using FIGS. 10 and 11. FIG. This embodiment is characterized in that it has a displacement portion 81 without using a fixing electromagnet 68 .
　図１０および図１１に示すように、前述の第２実施形態と同様に、本実施形態の操作ユニットＵ１の操作パネル１１Ｂは、断面形状がＣ字状に形成されている。そして制御ユニットＵ２の凹部７３に対向する部分には、駆動式ボールプランジャ７４Ｂが設けられ、駆動式ボールプランジャ７４Ｂのボール７５Ｂが凹部７３に嵌合する。 As shown in FIGS. 10 and 11, similarly to the above-described second embodiment, the operation panel 11B of the operation unit U1 of this embodiment has a C-shaped cross section. A drive type ball plunger 74B is provided in a portion facing the recess 73 of the control unit U2, and a ball 75B of the drive type ball plunger 74B fits into the recess 73. As shown in FIG.
　駆動式ボールプランジャ７４Ｂは、ボール７５Ｂを外側に付勢するばね７６Ｂ、およびボール７５Ｂを位置決めするピン８２を内蔵し、先端のボール７５Ｂが外からの荷重によって変位する。駆動式ボールプランジャ７４Ｂのボール７５Ｂは、荷重が作用していない無負荷状態では基準位置にあり、荷重が作用すると基端側に変位する。さらに駆動式ボールプランジャ７４Ｂのピン８２は、基準位置にあるボール７５Ｂを固定する固定位置と、ボール７５Ｂの変位を解除する解除位置とに変位する。ピン８２は、変位部８１の駆動力によって変位する。変位部８１は、電力で駆動し、たとえばモータと送り機構によって実現される。送り機構は、モータの回転運動をピン８２の直線運動に変換するボールねじおよび減速機などの要素部品で構成される。 The driven ball plunger 74B incorporates a spring 76B that urges the ball 75B outward and a pin 82 that positions the ball 75B, and the ball 75B at the tip is displaced by an external load. The ball 75B of the drive type ball plunger 74B is at the reference position in a non-loaded state, and is displaced toward the base end when a load is applied. Further, the pin 82 of the driven ball plunger 74B is displaced between a fixed position for fixing the ball 75B at the reference position and a release position for releasing the displacement of the ball 75B. The pin 82 is displaced by the driving force of the displacement portion 81 . Displacement portion 81 is driven by electric power and is realized by, for example, a motor and a feed mechanism. The feed mechanism is composed of element parts such as a ball screw and a speed reducer that convert the rotary motion of the motor into the linear motion of the pin 82 .
　制御マイコン４８は、検出部５０によって検出された変位が、通常の操作とは異なる特別な切替操作による変位である場合には、固定状態と解除状態とを切り替える切替信号を変位部８１に出力する。通常の操作は、１つの操作部１０を１秒以下の時間で押圧する操作であり、これによって押圧した操作部１０に割り当てられた制御を制御マイコン４８は実行する。これに対して、特別な切替操作とは、たとえば所定の操作部１０を通常よりも長く、数秒にわたって変位させる長押し操作、複数の操作部１０を同時に押圧する複数同時操作、および複数の操作部１０を所定の順番で押圧する順番操作などである。切替操作は、操作ユニットＵ１を取り外すときに行われる。 The control microcomputer 48 outputs a switching signal for switching between the fixed state and the released state to the displacement section 81 when the displacement detected by the detection section 50 is caused by a special switching operation different from the normal operation. . A normal operation is an operation of pressing one operation unit 10 for one second or less, and the control microcomputer 48 executes the control assigned to the operation unit 10 thus pressed. On the other hand, the special switching operation includes, for example, a long press operation of displacing a predetermined operation unit 10 for several seconds longer than usual, a multiple simultaneous operation of simultaneously pressing a plurality of operation units 10, and a It is a sequential operation of pressing 10 in a predetermined order. A switching operation is performed when the operation unit U1 is removed.
　変位部８１は、切替信号に応じて、操作ユニットＵ１を固定状態とする固定位置と、固定を解除する解除状態とする解除位置とにわたってピン８２を変位させる。これによって図１１に示す分離状態から、操作ユニットＵ１を左側へ変位させて、壁部７２がボール７５Ｂを下側に押圧することで、図１０の仮固定状態にすることができる。またボール７５Ｂが凹部７３に嵌合することで、制御ユニットＵ２と操作ユニットＵ１とを位置決めすることができる。 The displacement part 81 displaces the pin 82 between a fixed position where the operation unit U1 is fixed and a release position where the fixation is released according to the switching signal. As a result, the operation unit U1 is displaced leftward from the separated state shown in FIG. 11, and the wall portion 72 presses the ball 75B downward, whereby the temporary fixed state shown in FIG. 10 can be obtained. Further, by fitting the ball 75B into the concave portion 73, the control unit U2 and the operation unit U1 can be positioned.
　仮固定状態において切替操作がされると、制御マイコン４８は切替信号を変位部８１に与える。これによって変位部８１はピン８２を固定位置に変位させて、ボール７５Ｂの変位が規制される。ボール７５Ｂが図１０の下側に変位できないので、固定状態となる。 When a switching operation is performed in the temporarily fixed state, the control microcomputer 48 gives a switching signal to the displacement section 81 . As a result, the displacement portion 81 displaces the pin 82 to the fixed position, thereby restricting the displacement of the ball 75B. Since the ball 75B cannot be displaced downward in FIG. 10, it is in a fixed state.
　また固定状態において切替操作がされると、制御マイコン４８は切替信号を変位部８１に与える。これによって変位部８１はピン８２を解除位置に変位させて、ボール７５Ｂの変位が許容される。ボール７５Ｂが図１０の下側に変位することができ、仮固定状態となる。 Also, when a switching operation is performed in the fixed state, the control microcomputer 48 gives a switching signal to the displacement section 81 . As a result, the displacement portion 81 displaces the pin 82 to the release position, allowing the displacement of the ball 75B. The ball 75B can be displaced downward in FIG. 10 to be temporarily fixed.
　このように本実施形態の固定駆動部６４は、電力を用いて位置が変位する変位部８１によって実現される。そして変位部８１は、切替信号に応じて固定状態と解除状態とを切り替える。 As described above, the fixed driving portion 64 of the present embodiment is realized by the displacement portion 81 whose position is displaced using electric power. The displacement portion 81 switches between the fixed state and the released state according to the switching signal.
　また本実施形態では、イグニッションのオンの状態であっても、切替操作によって固定状態と解除状態とを切り替えることができる。これによって必要なタイミングで、操作ユニットＵ１を着脱することができる。また切替操作は操作部１０を用いるので、切替操作のための専用のボタンは不要である。 In addition, in this embodiment, even when the ignition is on, it is possible to switch between the fixed state and the released state by the switching operation. Accordingly, the operation unit U1 can be attached and detached at the required timing. Further, since the switching operation uses the operation unit 10, a dedicated button for the switching operation is unnecessary.
　好ましくは、イグニッションがオンであって、さらにサイドブレーキがオンであり、かつシフトレンジがパーキング位置にあるときに、制御マイコン４８は特別な操作に応じて切替信号を出力する。これによって走行中に切替信号が出力されることを抑制することができる。 Preferably, when the ignition is on, the side brake is on, and the shift range is in the parking position, the control microcomputer 48 outputs a switching signal in response to a special operation. As a result, it is possible to prevent the switching signal from being output while the vehicle is running.

For example, the conductor 15 of the operation unit 10 may be configured to contact the electrode of the control board 52 when the operation unit 10 is pressed. In this case, the control microcomputer 48 can detect the operation content of the operation unit 10 by determining whether or not the conductor 15 is in contact with the electrode.
