Description
本発明は、ダイアル操作部とプッシュ操作部とを備えたスイッチ装置に関し、特に車両用照光型スイッチ装置に関する。 The present invention relates to a switch device including a dial operation unit and a push operation unit, and more particularly to a vehicle illumination type switch device.
例えば、自動車に搭載される空気調和装置に関して、ダッシュボード等に設けた操作パネル部に複数（例えば３個）のダイアル式スイッチ装置が取り付けられ、各スイッチ装置を操作すると空気調和装置の稼動状態が調節できる。通常、これらのダイアル式スイッチ装置は、ポインタ（指標部）を有する回転式で中空筒状のダイアルノブ（ダイアル操作部）を操作（回転）して空気調和装置の設定温度の他、吐出風量（吹出し量）や吐出位置（吹出し口）をそれぞれ設定調節（選択）するために設けられる。ダイアルノブを回転操作したとき、ポインタによる設定位置は可変抵抗器（回転検出スイッチ部）によって検出される。また、ＬＥＤ等の発光部（光源）を内部に含む照光型のダイアル式スイッチでは、ダイアルノブの内側において、非回動式で透光性の表示部を軸線方向に移動可能なプッシュノブ（プッシュ操作部）とする場合がある。プッシュノブを押圧操作してＬＥＤを点灯させるので、主として夜間照明に用いられる。 For example, regarding an air conditioner mounted on an automobile, a plurality (for example, three) of dial type switch devices are attached to an operation panel provided on a dashboard or the like, and when each switch device is operated, the operating state of the air conditioner is Can be adjusted. Usually, these dial type switch devices operate (rotate) a rotary hollow cylindrical dial knob (dial operation unit) having a pointer (indicator unit), in addition to the set temperature of the air conditioner, and the discharge air volume ( It is provided to adjust (select) the discharge amount) and the discharge position (blowout port). When the dial knob is rotated, the setting position by the pointer is detected by a variable resistor (rotation detection switch unit). In an illuminated dial switch that includes a light emitting unit (light source) such as an LED, a push knob (push) that can move the non-rotating and translucent display unit in the axial direction inside the dial knob. Operation part). Since the LED is turned on by pressing the push knob, it is mainly used for night illumination.
そして、ダイアルノブの軸線に共通する入力軸を有し、可動部の回転に応じた電気信号を検出部（スイッチ部）から出力するとともに、プッシュノブの押し下げにより、可動部の移動に応じた電気信号を検出部（スイッチ部）から出力するダイアルプッシュスイッチ装置が開示されている（特許文献１参照）。 It has an input shaft that is common to the axis of the dial knob, and outputs an electrical signal corresponding to the rotation of the movable part from the detection part (switch part). A dial push switch device that outputs a signal from a detection unit (switch unit) is disclosed (see Patent Document 1).
特許文献１では、検出部（スイッチ部）がダイアルノブの軸線と共通の入力軸を有する、いわゆる軸タイプを用いることによって、ダイアルプッシュスイッチ装置の部品点数を減らして小型化を図ることができる。しかし、特許文献１に示す検出部（スイッチ部）では、可動部の回転と移動（スライド）とを同時に検出し、回転による信号と移動（押下）による信号とを同時に出力しなければならないため、検出部（スイッチ部）の構造が複雑になり高価になるおそれがある。また、軸タイプのダイアル式スイッチ装置をプッシュ式スイッチ装置にそのまま適用しようとしても、中心に位置する入力軸がＬＥＤによる夜間照明の光路を妨げるおそれがある。そこで、ＬＥＤでの発光を表示部や指標部に到達させるために、例えば、内面（表示部や指標部に対向する面）を反射面とするリフレクタ（反射板）等にさらなる工夫を加える必要がある。 In Patent Document 1, a so-called shaft type in which the detection unit (switch unit) has an input shaft common to the axis line of the dial knob can reduce the number of components of the dial push switch device, thereby reducing the size. However, the detection unit (switch unit) shown in Patent Document 1 must detect the rotation and movement (slide) of the movable unit at the same time, and simultaneously output a signal due to rotation and a signal due to movement (pressing). The structure of the detection unit (switch unit) may be complicated and expensive. Further, even if the shaft type dial type switch device is applied to the push type switch device as it is, the input shaft located at the center may interfere with the light path of night illumination by the LED. Therefore, in order to cause the light emitted from the LED to reach the display unit or the indicator unit, for example, it is necessary to add further contrivance to a reflector (reflector plate) having an inner surface (a surface facing the display unit or the index unit) as a reflection surface. is there.
本発明の課題は、スイッチ部における回転検出及び移動検出を容易とし、小型化とコストダウンを図ることのできるスイッチ装置を提供することにある。さらには、光源による発光を表示部や指標部の照明に無駄なく使用できるスイッチ装置を提供する。 An object of the present invention is to provide a switch device that facilitates rotation detection and movement detection in a switch unit, and can achieve downsizing and cost reduction. Furthermore, the present invention provides a switch device that can use light emitted from a light source for illumination of a display unit and an indicator unit without waste.
上記課題を解決するために、本発明のスイッチ装置は、
軸線周りに回転して人為的に位置設定される透光性の指標部を有する中空回転式のダイアル操作部と、その指標部による設定位置を検出する回転検出スイッチ部と、前記ダイアル操作部の内側に対向配置されて前記指標部による設定位置を示すための透光性の表示部を有し人為操作により軸線方向に移動可能なプッシュ操作部と、そのプッシュ操作部の軸線方向への移動を検出するための移動検出スイッチ部とを備えるスイッチ装置であって、
前記回転検出スイッチ部は、前記ダイアル操作部と軸線を共有する入力軸の回転により前記指標部の角度変位を検出するように、そのダイアル操作部から伝達機構を介して伝達され、
前記移動検出スイッチ部は、前記回転検出スイッチ部の入力軸の外側に配設され、前記プッシュ操作部の軸線方向への変位を検出することにより電気的にＯＮ・ＯＦＦされ、
これら回転検出スイッチ部及び移動検出スイッチ部は、前記ダイアル操作部及びプッシュ操作部を非表示面側から覆う基板に対して、前記プッシュ操作部を軸線方向に投影した領域内に位置する形態で配置されることを特徴とする。
In order to solve the above problems, the switch device of the present invention provides:
A hollow rotary dial operation unit having a translucent indicator portion that is rotated around an axis and artificially set, a rotation detection switch portion that detects a setting position by the indicator portion, and the dial operation portion A push operation unit that is disposed oppositely on the inside and has a translucent display unit for indicating a setting position by the indicator unit and is movable in the axial direction by human operation, and movement of the push operation unit in the axial direction A switch device comprising a movement detection switch unit for detecting,
The rotation detection switch unit is transmitted from the dial operation unit via a transmission mechanism so as to detect angular displacement of the index unit by rotation of an input shaft sharing an axis with the dial operation unit,
The movement detection switch unit is disposed outside the input shaft of the rotation detection switch unit, and is electrically turned ON / OFF by detecting displacement in the axial direction of the push operation unit,
The rotation detection switch unit and the movement detection switch unit are arranged in a form in which the push operation unit is positioned in a region projected in the axial direction with respect to the substrate that covers the dial operation unit and the push operation unit from the non-display surface side. It is characterized by being.
このように、ダイアル操作部（例えばダイアルノブ）の指標部（例えばポインタ）の角度変位は回転検出スイッチ部（例えば可変抵抗器）によって、一方プッシュ操作部の軸線方向への移動は移動検出スイッチ部（例えばタクトスイッチ）によって検出される。これによって、両スイッチ部における検出が容易になり、誤検出もしにくくなる。また、回転検出スイッチ部及び移動検出スイッチ部が、基板に対してプッシュ操作部を軸線方向に投影した領域内に位置する形態で、すなわち表示部の面積（表示面積）内に、配置されるので、小型化とコストダウンが実現できる。 Thus, the angular displacement of the indicator portion (eg, pointer) of the dial operation portion (eg, dial knob) is caused by the rotation detection switch portion (eg, variable resistor), while the movement of the push operation portion in the axial direction is the movement detection switch portion. (For example, a tact switch). This facilitates detection in both switch sections and makes it difficult to detect errors. Further, since the rotation detection switch unit and the movement detection switch unit are arranged in a form in which the push operation unit is projected in the axial direction with respect to the substrate, that is, within the area (display area) of the display unit. Downsizing and cost reduction can be realized.
その際、回転検出スイッチ部の本体部を基板の非表示面側に配置し、その本体部よりも細く形成された入力軸のみを基板の表示面側に突出配置することが望ましい。これによって、基板の表示面側に回転検出スイッチ部の本体部が突出しないので、基板を広く利用することができる（例えば後述する光源等を実装することができる）。 At this time, it is desirable that the main body portion of the rotation detection switch portion is disposed on the non-display surface side of the substrate, and only the input shaft formed narrower than the main body portion is disposed so as to protrude toward the display surface side of the substrate. As a result, the main body of the rotation detection switch unit does not protrude from the display surface side of the substrate, so that the substrate can be widely used (for example, a light source described later can be mounted).
なお、回転検出スイッチ部には、ダイアル式スイッチ装置において軸タイプと称される可変抵抗器、エンコーダ、パルス発生器等を用いることができ、また、一般的に直切スイッチと言われる、いわゆる大電流タイプにも適用できる。 The rotation detection switch unit may be a variable resistor, encoder, pulse generator, or the like called a shaft type in a dial type switch device, and a so-called large switch generally called a direct cut switch. Applicable to current type.
また、このようなスイッチ装置において、
基板には、移動検出スイッチ部のＯＮ・ＯＦＦに伴って点灯・消灯する光源が、プッシュ操作部を軸線方向に投影した領域内に位置する形態で実装され、
伝達機構は、回転検出スイッチ部の入力軸からダイアル操作部の外周部へ半径方向外側に向って連結する連結部材を有し、
ダイアル操作部及びプッシュ操作部を保持するとともに表示面側に光を反射させる反射面を有する保持部材の内部に、回転検出スイッチ部の入力軸、移動検出スイッチ部、連結部材及び光源が収容され、
その光源からの光は、連結部材の非存在領域を通り、保持部材の反射面で反射して、プッシュ操作部の表示部を照明することができる。
In such a switch device,
On the board, a light source that is turned on / off in accordance with ON / OFF of the movement detection switch unit is mounted in a form in which the push operation unit is located in a region projected in the axial direction,
The transmission mechanism includes a connecting member that is connected radially outward from the input shaft of the rotation detection switch unit to the outer periphery of the dial operation unit,
An input shaft of the rotation detection switch unit, a movement detection switch unit, a connecting member, and a light source are housed in a holding member that holds the dial operation unit and the push operation unit and has a reflection surface that reflects light on the display surface side.
The light from the light source can pass through the non-existing region of the connecting member, be reflected by the reflecting surface of the holding member, and illuminate the display unit of the push operation unit.
このように、光源も上記した表示部の面積（表示面積）内の基板に実装されるので、さらなる小型化とコストダウンが実現できる。そして、光源による発光を表示部や指標部の照明に無駄なく使用できる。なお、このとき光源は回転検出スイッチ部の入力軸の周囲に同心円状に所定間隔（例えば１２０°間隔）で複数（例えば３個）配置すると、表示部や指標部の照明をさらに高められる。 As described above, since the light source is also mounted on the substrate within the area of the display unit (display area), further downsizing and cost reduction can be realized. The light emitted from the light source can be used for illumination of the display unit and the indicator unit without waste. At this time, if a plurality of (for example, three) light sources are arranged concentrically around the input shaft of the rotation detection switch unit at predetermined intervals (for example, 120 ° intervals), the illumination of the display unit and the indicator unit can be further enhanced.
さらに、連結部材を透光性の材料で構成し、光源からの光が連結部材を透過し、保持部材の反射面で反射して、ダイアル操作部の指標部を照明するようにすれば、基板上の光源からの光は連結部材を透過して一層指標部に到達しやすくなる。 Further, if the connecting member is made of a light-transmitting material, light from the light source is transmitted through the connecting member, reflected by the reflecting surface of the holding member, and illuminates the indicator portion of the dial operation unit, the substrate Light from the upper light source passes through the connecting member and more easily reaches the indicator portion.
そして、ダイアル操作部と連結部材とは、それぞれ個別に保持部材に回転可能に支持されるとともに、ダイアル操作部と連結部材との間には、両者が軸線周りで同期回転できるように係合部を形成している。このように、固定部を構成する保持部材を介してダイアル操作部と連結部材とを接続することによって、ダイアル操作部の回転操作に伴うスイッチ装置の撓み（歪）を減少させ、ダイアル調整を円滑に行なえる。 The dial operation portion and the connection member are individually supported by the holding member so as to be rotatable, and the engagement portion is provided between the dial operation portion and the connection member so that both can rotate synchronously around the axis. Is forming. In this way, by connecting the dial operation unit and the connecting member via the holding member constituting the fixing unit, the deflection (distortion) of the switch device accompanying the rotation operation of the dial operation unit is reduced, and the dial adjustment is smoothly performed. It can be done.
なお、ダイアル操作部と保持部材との接続は、例えば、円環状のダイアル操作部に周方向に沿って複数突出形成した突出部を円環状の保持部材に周方向に沿って複数形成した凹部に嵌合し、その嵌合を保ちつつ同期回転動してもよい。同様に、連結部材と保持部材との接続は、例えば、円環状の保持部材に周方向に沿って複数突出形成した突出部を円環状の連結部材に周方向に沿って複数形成した凹部に嵌合し、その嵌合を保ちつつ同期回転してもよい。また、ダイアル操作部と連結部材との間に形成される係合部は、例えば連結部材に突出部、ダイアル操作部に凹部（溝、切欠）が形成され、両者を係合させて一体的に回転できるようにすればよい。 The dial operating part and the holding member are connected to, for example, an annular dial operating part formed by a plurality of protruding parts formed along the circumferential direction on a concave part formed on the annular holding member along the circumferential direction. They may be fitted and rotated synchronously while keeping the fit. Similarly, the connection between the connecting member and the holding member is performed by, for example, fitting an annular holding member with a plurality of protruding portions formed along the circumferential direction into a recessed portion formed with a plurality of annular connecting members along the circumferential direction. And may rotate synchronously while maintaining the fitting. In addition, the engaging portion formed between the dial operation portion and the connecting member is formed by, for example, forming a protruding portion on the connecting member and a recess (groove, notch) on the dial operating portion, and engaging both to form an integral part. It only needs to be able to rotate.
このうち、ダイアル操作部と保持部材とは、半径の異なる複数の円弧状支持部を周方向に位相をずらして形成することができる。これによって、ダイアル操作部の回転調整範囲を広く形成することができる。例えば保持部材に複数の円弧状溝を周方向に位相をずらして形成し、ダイアル操作部の複数の突出部を各溝に挿入すればよい。 Among these, the dial operation part and the holding member can be formed by shifting a plurality of arcuate support parts having different radii in the circumferential direction. This makes it possible to widen the rotation adjustment range of the dial operation unit. For example, a plurality of arc-shaped grooves may be formed in the holding member with the phases shifted in the circumferential direction, and a plurality of protrusions of the dial operation unit may be inserted into each groove.
ダイアル操作部と連結部材との間に形成される係合部のうち、ダイアル操作部側の係合部を指標部に形成するときには、光源からの光は連結部材から直接指標部に導入されるので、指標部を浮き立つように照明することができる。 Of the engaging portions formed between the dial operating portion and the connecting member, when the engaging portion on the dial operating portion side is formed on the indicator portion, the light from the light source is directly introduced into the indicator portion from the connecting member. Therefore, it can illuminate so that an indicator part may stand up.

(Example)

FIG. In an in-vehicle air conditioner unit, an air conditioner switch panel to which a plurality of (for example, three) switch devices are attached is mounted on the vehicle body (main body) side of an automobile. Usually, these switch devices are a temperature setting switch device for setting the temperature of the air conditioner unit 1, an air volume setting switch device for setting the air volume (blowout amount), and a outlet port (discharge position). And an outlet setting switch device. However, since the internal structure is the same, the air volume setting switch device will be described as a representative example here.
図１及び図２に示すように、風量設定スイッチ装置（以下、単にスイッチ装置ともいう）１は、主要構造として、軸線周りに回転して人為的に位置設定されるポインタ１１（指標部）を有する中空回転式のダイアルノブ１０（ダイアル操作部）と、ポインタ１１による設定位置を検出する軸タイプスイッチ６０（回転検出スイッチ部）と、ダイアルノブ１０の内側に対向配置されてポインタ１１による設定位置を示すための表示部２１，２２を有し人為操作により軸線方向に移動可能なプッシュノブ２０（プッシュ操作部）と、プッシュノブ２０の軸線方向への移動を検出するためのタクトスイッチ５１（移動検出スイッチ部）とを備える。プッシュノブ２０とダイアルノブ１０とは内外二重円筒状に重ね合わせられている。プッシュノブ２０の表示面側には、ポインタ１１による設定位置を示すために、数字、図形、記号、符号、目盛等の目印を印刷、刻設等によって形成したシンボル表示部２１と、作動状態にあることを点灯により報知するインジケータ表示部２２とが形成されている。そして、ポインタ１１とインジケータ表示部２２とは透光性材料（例えばレンズ体）で形成されている。 As shown in FIGS. 1 and 2, an air volume setting switch device (hereinafter also simply referred to as a switch device) 1 has, as a main structure, a pointer 11 (index unit) that is artificially positioned by rotating around an axis. A hollow rotary dial knob 10 (dial operation unit), a shaft type switch 60 (rotation detection switch unit) for detecting a setting position by the pointer 11, and a setting position by the pointer 11 which is disposed opposite to the inside of the dial knob 10. And a push knob 20 (push operation unit) that can be moved in the axial direction by human operation, and a tact switch 51 (movement) for detecting the movement of the push knob 20 in the axial direction. Detection switch unit). The push knob 20 and the dial knob 10 are overlapped in an inner and outer double cylindrical shape. On the display surface side of the push knob 20, in order to indicate the set position by the pointer 11, a symbol display unit 21 formed by printing, engraving, or the like, such as numerals, figures, symbols, signs, scales, etc. An indicator display unit 22 for notifying that there is a light is formed. The pointer 11 and the indicator display unit 22 are made of a translucent material (for example, a lens body).
ポインタ１１の角度変位がダイアルノブ１０からダイアルリング３０（連結部材；伝達機構）を介して軸タイプスイッチ６０へ伝達される。したがって、軸タイプスイッチ６０は、ダイアルノブ１０と軸線Ｏを共有する入力軸６２の回転によりポインタ１１の角度変位を検出する可変抵抗器（図示せず）を含む。ダイアルリング３０は、軸タイプスイッチ６０の入力軸６２側の中心部３１からダイアルノブ１０側と接続される外周部３２へ半径方向外側に向って延びる連結部３３を有する。一方、タクトスイッチ５１は、軸タイプスイッチ６０の入力軸６２の外側に配設され、プッシュノブ２０の押圧部２３（図４参照）の軸線Ｏ方向への変位を検出することにより電気的にＯＮ・ＯＦＦする。なお、プッシュノブ２０の円筒部は、後述するリフレクタ４０（保持部材）のレール部４１（図７参照）により、上下昇降の際その内側をガイドされる。また、タクトスイッチ５１には、押圧部２３を元の位置（上方位置）に戻すように作用する復帰ばね（図示せず）が内蔵されている。 The angular displacement of the pointer 11 is transmitted from the dial knob 10 to the shaft type switch 60 via the dial ring 30 (connecting member; transmission mechanism). Accordingly, the shaft type switch 60 includes a variable resistor (not shown) that detects the angular displacement of the pointer 11 by the rotation of the input shaft 62 that shares the axis O with the dial knob 10. The dial ring 30 has a connecting portion 33 that extends radially outward from the center portion 31 on the input shaft 62 side of the shaft type switch 60 to the outer peripheral portion 32 connected to the dial knob 10 side. On the other hand, the tact switch 51 is disposed outside the input shaft 62 of the shaft type switch 60, and is electrically turned on by detecting the displacement of the pressing portion 23 (see FIG. 4) of the push knob 20 in the axis O direction. -Turn off. Note that the cylindrical portion of the push knob 20 is guided on the inner side in the vertical movement by a rail portion 41 (see FIG. 7) of a reflector 40 (holding member) described later. The tact switch 51 incorporates a return spring (not shown) that acts to return the pressing portion 23 to its original position (upper position).
軸タイプスイッチ６０は、ダイアルノブ１０及びプッシュノブ２０を非表示面（下面）側から覆う基板５０に対して、プッシュノブ２０を軸線Ｏの方向に投影した領域内に位置している（図４参照）。具体的には、軸タイプスイッチ６０の本体部６１は基板５０の非表示面側に配置され、本体部よりも細く形成された入力軸６２のみが基板５０の表示面側に突出配置されている。 The shaft type switch 60 is located in a region where the push knob 20 is projected in the direction of the axis O with respect to the substrate 50 that covers the dial knob 10 and the push knob 20 from the non-display surface (lower surface) side (FIG. 4). reference). Specifically, the main body portion 61 of the shaft type switch 60 is disposed on the non-display surface side of the substrate 50, and only the input shaft 62 formed narrower than the main body portion is disposed so as to protrude from the display surface side of the substrate 50. .
また、基板５０には、タクトスイッチ５１が、プッシュノブ２０を軸線Ｏ方向に投影した領域内に位置する形態で実装されている。同様に、基板５０には、タクトスイッチ５１のＯＮ・ＯＦＦに伴って点灯・消灯するＬＥＤ５２（発光部；光源）が、プッシュノブ２０を軸線Ｏ方向に投影した領域内に位置する形態で実装されている。 In addition, a tact switch 51 is mounted on the substrate 50 so as to be positioned in a region where the push knob 20 is projected in the direction of the axis O. Similarly, an LED 52 (light emitting unit; light source) that is turned on / off when the tact switch 51 is turned on / off is mounted on the substrate 50 in a form in which the push knob 20 is located in a region projected in the direction of the axis O. ing.
図２〜図４に示すように、リフレクタ４０（保持部材）は、ダイアルノブ１０及びプッシュノブ２０を保持して表示面側に光を反射させる反射面を有している。そして、リフレクタ４０の内部には、軸タイプスイッチ６０の入力軸６２、タクトスイッチ５１、ダイアルリング３０及びＬＥＤ５２が収容されている。なお、ＬＥＤ５２は軸タイプスイッチ６０の入力軸６２の周囲に同心円状に所定間隔（例えば１２０°間隔）で複数（例えば３個）配置されている（図５参照）。また、ダイアルリング３０は透光性の材料（例えば透明又は半透明の高分子材料）で構成されている。 As shown in FIGS. 2 to 4, the reflector 40 (holding member) has a reflecting surface that holds the dial knob 10 and the push knob 20 and reflects light to the display surface side. In the reflector 40, the input shaft 62 of the shaft type switch 60, the tact switch 51, the dial ring 30, and the LED 52 are accommodated. Note that a plurality of (for example, three) LEDs 52 are concentrically arranged around the input shaft 62 of the shaft type switch 60 at predetermined intervals (for example, 120 ° intervals) (see FIG. 5). The dial ring 30 is made of a translucent material (for example, a transparent or translucent polymer material).
したがって、図２〜図４から明らかなように、ＬＥＤ５２からの光は直接的にポインタ１１を照明する。また、ＬＥＤ５２からの光はダイアルリング３０の連結部３３の非存在領域及びダイアルリング３０を透過し、リフレクタ４０の反射面で反射して、プッシュノブ２０の表示部２１を照明する。さらに、ＬＥＤ５２からの光は直接的にプッシュノブ２０の表示部２２を照明する。 Therefore, as apparent from FIGS. 2 to 4, the light from the LED 52 directly illuminates the pointer 11. The light from the LED 52 passes through the non-existing region of the connecting portion 33 of the dial ring 30 and the dial ring 30 and is reflected by the reflecting surface of the reflector 40 to illuminate the display portion 21 of the push knob 20. Further, the light from the LED 52 directly illuminates the display unit 22 of the push knob 20.
なお、図５において、符号２はダイアルノブ１０とプッシュノブ２０とを保持しつつリフレクタ４０に固定保持されるベゼル、符号３はリフレクタ４０に基板５０を挟み込んで固定保持するためのケース、符号４はそのケースに軸タイプスイッチ６０を固定するためのナットである。 In FIG. 5, reference numeral 2 denotes a bezel that is fixedly held by the reflector 40 while holding the dial knob 10 and the push knob 20, and reference numeral 3 denotes a case for sandwiching and fixing the substrate 50 to the reflector 40, reference numeral 4. Is a nut for fixing the shaft type switch 60 to the case.
次に、図６〜図１０を用いて、リフレクタ４０を中心とした取付構造及び作動状態の詳細を説明する。 Next, with reference to FIGS. 6 to 10, the details of the mounting structure and the operating state centered on the reflector 40 will be described.
図６に示すように、ダイアルノブ１０とダイアルリング３０とは、それぞれ個別にリフレクタ４０に回転可能に支持されている。具体的には、ダイアルノブ１０とリフレクタ４０との接続は、円環状のダイアルノブ１０の先端部に周方向に沿って複数（例えば３個）突出形成した突出部１２（ダイアル操作部側係止部）を円環状のリフレクタ４０の先端部に周方向に沿って複数（例えば３個）形成した凹部４２（保持部材側係止部）に嵌合し、その嵌合を保ちつつ同期回転する。同様に、ダイアルリング３０とリフレクタ４０との接続は、円環状のリフレクタ４０の先端部に周方向に沿って複数（例えば３個）突出形成した突出部４３（保持部材側係止部）を円環状のダイアルリング３０に周方向に沿って複数（例えば３個）形成した凹部３４（連結部材側係止部）に嵌合し、その嵌合を保ちつつ同期回転する。 As shown in FIG. 6, the dial knob 10 and the dial ring 30 are individually supported by the reflector 40 so as to be rotatable. Specifically, the dial knob 10 and the reflector 40 are connected to each other by a plurality of protrusions 12 (for example, three) protruding along the circumferential direction at the tip of the annular dial knob 10 (dial operation part side locking). Portion) is fitted into a plurality of (for example, three) recesses 42 (holding member side latching portions) formed along the circumferential direction at the tip of the annular reflector 40, and synchronously rotates while maintaining the fitting. Similarly, the dial ring 30 and the reflector 40 are connected by connecting a plurality of (for example, three) protrusions 43 (holding member side locking portions) formed at the tip of the annular reflector 40 along the circumferential direction. The ring-shaped dial ring 30 is fitted into a plurality of (for example, three) concave portions 34 (connection member side locking portions) formed along the circumferential direction, and rotates synchronously while maintaining the fitting.
そして、ダイアルノブ１０とダイアルリング３０との間には、軸線Ｏ周りで同期回転できるように係合部１３，３５が形成されている。具体的には、ダイアルノブ１０とダイアルリング３０との係合は、ダイアルノブ１０の先端部に凹部１３（ダイアル操作部側係合部）を形成する一方、ダイアルリング３０に突出部３５（連結部材側係合部）を形成し、両者を係合させて一体的に回転させる。 Engaging portions 13 and 35 are formed between the dial knob 10 and the dial ring 30 so that they can rotate synchronously around the axis O. Specifically, the dial knob 10 and the dial ring 30 are engaged with each other by forming a concave portion 13 (dial operation portion side engaging portion) at the tip end portion of the dial knob 10 and a protruding portion 35 (connection) on the dial ring 30. Member side engaging portion) is formed, and both are engaged and rotated together.
このように、固定部を構成するリフレクタ４０を介してダイアルノブ１０とダイアルリング３０とを接続することによって、ダイアルノブ１０の回転操作に伴うスイッチ装置１の撓み（歪）を減少させ、ダイアル調整を円滑に行なえる。 In this way, by connecting the dial knob 10 and the dial ring 30 via the reflector 40 that constitutes the fixed portion, the deflection (distortion) of the switch device 1 accompanying the rotation operation of the dial knob 10 is reduced, and dial adjustment is performed. Can be done smoothly.
なお、図７に示すように、ダイアルノブ１０とリフレクタ４０との接続において、リフレクタ４０に複数（例えば３本）の円弧状溝４４（円弧状支持部）を周方向に位相をずらしてレール状に形成し、上記したダイアルノブ１０の複数（例えば３個）の突出部１２を各溝４４に挿入する。これによって、ダイアルノブ１０の回転調整範囲を広く形成することができる。 As shown in FIG. 7, when the dial knob 10 and the reflector 40 are connected, a plurality of (for example, three) arc-shaped grooves 44 (arc-shaped support portions) are shifted in the circumferential direction in the reflector 40 to form a rail shape. The plurality of (for example, three) protrusions 12 of the dial knob 10 described above are inserted into the grooves 44. Thereby, the rotation adjustment range of the dial knob 10 can be formed wide.
また、ダイアルノブ１０とダイアルリング３０との間に形成される係合部１３，３５のうち、ダイアルノブ１０側の係合部１３はポインタ１１に形成してある。この場合、ＬＥＤ５２からの光は直接的にポインタ１１に導入されるので、ポインタ１１を浮き立つように照明することができる。 Of the engaging portions 13 and 35 formed between the dial knob 10 and the dial ring 30, the engaging portion 13 on the dial knob 10 side is formed on the pointer 11. In this case, since the light from the LED 52 is directly introduced into the pointer 11, the pointer 11 can be illuminated so as to float.
図８〜図１０によりダイアルリング３０の作動の要部を説明する。図８及び図６，図１に共通して示すようにポインタ１１（凹部１３）が中央上部にある状態から、図９に示すようにポインタ１１（凹部１３）が右側（図９では左側）にある状態へダイアルノブ１０を約９０°回転操作する。このとき、ダイアルノブ１０の凹部１３とダイアルリング３０の突出部３５との嵌合状態に変化はないので、ダイアルノブ１０とダイアルリング３０とは同期して一体的に右側へ回転する。 The main part of the operation of the dial ring 30 will be described with reference to FIGS. As shown in FIGS. 8, 6 and 1, the pointer 11 (recessed portion 13) is located at the center upper portion, and the pointer 11 (recessed portion 13) is moved to the right side (left side in FIG. 9) as shown in FIG. The dial knob 10 is rotated about 90 ° to a certain state. At this time, since there is no change in the fitting state between the concave portion 13 of the dial knob 10 and the protruding portion 35 of the dial ring 30, the dial knob 10 and the dial ring 30 rotate integrally to the right in synchronization.
同様に、図８及び図６，図１に共通して示すようにポインタ１１（凹部１３）が中央上部にある状態から、図１０に示すようにポインタ１１（凹部１３）が左側（図１０では右側）にある状態へダイアルノブ１０を約９０°回転操作する。このとき、ダイアルノブ１０の凹部１３とダイアルリング３０の突出部３５との嵌合状態に変化はないので、ダイアルノブ１０とダイアルリング３０とは同期して一体的に左側へ回転する。 Similarly, from the state where the pointer 11 (recess 13) is at the upper center as shown in FIGS. 8, 6 and 1, the pointer 11 (recess 13) is left (as shown in FIG. 10). The dial knob 10 is rotated about 90 ° to the state on the right side. At this time, since there is no change in the fitting state between the recessed portion 13 of the dial knob 10 and the protruding portion 35 of the dial ring 30, the dial knob 10 and the dial ring 30 rotate integrally to the left.
このように、ダイアルノブ１０のポインタ１１の角度変位は軸タイプスイッチ６０（例えば可変抵抗器）によって、一方プッシュノブ２０の軸線方向への移動はタクトスイッチ５１によって検出される。これによって、両スイッチ６０，５１における検出が容易になり、誤検出もしにくくなる。また、軸タイプスイッチ６０及びタクトスイッチ５１が、基板５０に対してプッシュノブを軸線方向に投影した領域内に位置する形態で、すなわちプッシュノブ２０の面積（表示面積）内に、配置されるので、小型化とコストダウンが実現できる。 Thus, the angular displacement of the pointer 11 of the dial knob 10 is detected by the shaft type switch 60 (for example, a variable resistor), while the movement of the push knob 20 in the axial direction is detected by the tact switch 51. As a result, detection by both switches 60 and 51 is facilitated, and erroneous detection is less likely to occur. In addition, the shaft type switch 60 and the tact switch 51 are arranged in a form in which the push knob is projected in the axial direction with respect to the substrate 50, that is, within the area (display area) of the push knob 20. Downsizing and cost reduction can be realized.

において、「突出部」と「凹部」とを相互に入れ替えて実施することができる。さらに、「突出部」や「凹部」のそれぞれについて、以上で説明した形状を変形してもよい。例えば、「突出部」では、実施例に示す板状、爪状以外に球状、円柱状、多角柱状等のオス型形状であればよく、「凹部」では、実施例に示す切欠状、窪み状以外に溝状、アリ溝状、孔あき状等のメス型形状であればよい。
