また、レバースイッチ装置１は、第１の回転軸Ｌ１を軸とする第１の回転操作、及び第１の回転軸Ｌ１と交差する第２の回転軸Ｌ２を軸とする第２の回転操作が可能な操作部と、操作部になされた第１の回転操作をマグネット５０の第３の回転軸Ｌ３の周りの回転に変換する第１の変換部と、操作部になされた第２の回転操作をマグネット５０と配置面１０１との相対移動に変換する第２の変換部と、を有する。 Further, the lever switch device 1 is configured to perform a first rotation operation about the first rotation axis L1 and a second rotation operation about the second rotation axis L2 intersecting the first rotation axis L1. A possible operation unit, a first conversion unit that converts the first rotation operation performed on the operation unit into a rotation around the third rotation axis L3 of the magnet 50, and a second rotation operation performed on the operation unit And a second conversion unit that converts relative movement between the magnet 50 and the arrangement surface 101.
操作部は、一例として、操作レバー１０である。第１の変換部は、一例として、ブラケット３０である。第２の変換部は、一例として、ホルダ４０である。 The operation unit is an operation lever 10 as an example. The 1st conversion part is bracket 30 as an example. The 2nd conversion part is holder 40 as an example.
また、レバースイッチ装置１は、図３に示されるように、筐体２０と、ブラケット３０と、マグネットホルダ７０と、を有する。 Moreover, the lever switch apparatus 1 has the housing | casing 20, the bracket 30, and the magnet holder 70, as FIG. 3 shows.
ここで、図３で示す第１の回転軸Ｌ１の回りの第１の回転操作の方向は、図２に示す矢印ＴＬ方向、及び矢印ＴＬ方向とは逆方向となる矢印ＴＲ方向の操作を示している。この矢印ＴＬ方向の操作は、例えば、車両５の左側のウインカー（方向指示器）を点滅させる左折操作である。また矢印ＴＲ方向の操作は、例えば、右側のウインカー（方向指示器）を点滅させる右折操作である。すなわち、第１の回転操作は、左折又は右折のためのウインカー（方向指示器）操作であり、操作レバー１０のターン操作である。 Here, the direction of the first rotation operation around the first rotation axis L1 shown in FIG. 3 indicates the operation in the arrow TL direction shown in FIG. 2 and the operation in the arrow TR direction which is opposite to the arrow TL direction. ing. The operation in the direction of the arrow TL is, for example, a left turn operation for blinking the left turn signal (direction indicator) of the vehicle 5. The operation in the direction of the arrow TR is, for example, a right turn operation for blinking the right turn signal (direction indicator). That is, the first rotation operation is a winker (direction indicator) operation for left or right turn, and is a turn operation of the operation lever 10.
一方、図３で示す第２の回転軸Ｌ２の回りの第２の回転操作の方向は、図２に示す矢印Ｄ方向、及び矢印Ｄ方向とは逆方向となる矢印Ｐ方向の操作を示している。この矢印Ｄ方向の操作は、例えば、車両５のヘッドランプの光軸を上向きに切り替える操作（ディマＨＵ操作）である。また矢印Ｐ方向の操作は、例えば、操作を維持している間、ヘッドライトの光軸を上向きに切り替える操作（パッシング操作）である。レバースイッチ装置１は、例えば、矢印Ｐ方向の操作に対しては、操作が終了した後に中立位置に復帰するモーメンタリースイッチとして構成されている。またレバースイッチ装置１は、例えば、矢印Ｄ方向の操作に対しては、操作が終了した後、中立位置に復帰せず、矢印Ｄ方向に操作レバー１０が操作された状態が維持されるように構成されている。すなわち、第２の回転操作は、ヘッドランプの光軸を切り替える操作であり、操作レバー１０のディマ操作である。 On the other hand, the direction of the second rotation operation around the second rotation axis L2 shown in FIG. 3 indicates the operation in the arrow D direction shown in FIG. 2 and the operation in the arrow P direction opposite to the arrow D direction. Yes. The operation in the direction of arrow D is, for example, an operation (dimmer HU operation) for switching the optical axis of the headlamp of the vehicle 5 upward. The operation in the arrow P direction is, for example, an operation (passing operation) for switching the optical axis of the headlight upward while maintaining the operation. For example, the lever switch device 1 is configured as a momentary switch that returns to the neutral position after the operation is completed for the operation in the direction of the arrow P. In addition, for example, for the operation in the direction of the arrow D, the lever switch device 1 does not return to the neutral position after the operation is completed, but maintains the state in which the operation lever 10 is operated in the direction of the arrow D. It is configured. That is, the second rotation operation is an operation of switching the optical axis of the headlamp, and is a dimmer operation of the operation lever 10.
上述の第１の操作方向は、図２に示すレバースイッチ装置１の上部筐体２１が、操作者に向くように車両５に配置されるので、操作者から見て図２の上下方向に操作する方向となる。この上方向の操作は、矢印ＴＬ方向の操作であり、下方向の操作は、矢印ＴＲ方向の操作である。また第２の操作方向は、操作者から見て前後方向に操作する方向となる。この前方向の操作は、矢印Ｐ方向の操作であり、操作レバー１０を操作者側に引き寄せるような操作となる。また後方向の操作とは、矢印Ｄ方向の操作であり、操作レバー１０を操作者から遠ざけるような操作となる。 Since the upper casing 21 of the lever switch device 1 shown in FIG. 2 is arranged in the vehicle 5 so as to face the operator, the first operation direction described above is operated in the vertical direction of FIG. 2 as viewed from the operator. It becomes the direction to do. The upward operation is an operation in the arrow TL direction, and the downward operation is an operation in the arrow TR direction. In addition, the second operation direction is a direction to operate in the front-rear direction as viewed from the operator. This forward operation is an operation in the direction of arrow P, and is an operation that pulls the operation lever 10 toward the operator. The backward operation is an operation in the direction of arrow D, and is an operation that moves the operation lever 10 away from the operator.
なお、この矢印ＴＬ方向及び矢印ＴＲ方向の操作により操作レバー１０が形成する操作面と、矢印Ｄ方向及び矢印Ｐ方向の操作により操作レバー１０が形成する操作面とは、交差し、実質的に直交する。 The operation surface formed by the operation lever 10 by the operation in the arrow TL direction and the arrow TR direction intersects with the operation surface formed by the operation lever 10 by the operation in the arrow D direction and the arrow P direction. Orthogonal.

下部筐体２２は、図３に示されるように、下側から、マグネットホルダ７０、基板１００が固定されている。 As shown in FIG. 3, the magnet holder 70 and the substrate 100 are fixed to the lower housing 22 from the lower side.
（ブラケット３０の構成）
ブラケット３０は、第１の回転軸Ｌ１に、回転軸部３１が突出して形成され、また、図４に示されるように、環状壁部３２が形成されている。これにより、ブラケット３０は、第１の回転軸Ｌ１の回りに所定角度（ターン操作に必要な角度）だけ回転移動可能な状態で筐体２０の中に収容される。 (Configuration of bracket 30)

Thereby, the bracket 30 is accommodated in the housing 20 in a state in which the bracket 30 can be rotated about the first rotation axis L1 by a predetermined angle (an angle necessary for the turn operation).
ブラケット３０には、第２の回転軸Ｌ２に、操作レバー１０の回転軸部１３と回転可能に嵌合して支持する支持穴部３３が形成されている。これにより、ブラケット３０は、内部に、第２の回転軸Ｌ２の回りのディマ操作の方向にブラケット３０と独立に回転移動可能な状態で、操作レバー１０を収容する。 The bracket 30 is formed with a support hole portion 33 that is rotatably fitted to and supported by the rotation shaft portion 13 of the operation lever 10 on the second rotation shaft L2. Thereby, the bracket 30 accommodates the operation lever 10 in a state in which the bracket 30 can rotate and move independently of the bracket 30 in the direction of the dimmer operation around the second rotation axis L2.
ブラケット３０は、第１の回転軸Ｌ１から離間した位置に、上述するマグネット５０を回転駆動するための駆動突起部３４が形成されている。この駆動突起部３４は、操作レバー１０のターン操作により、第１の回転軸Ｌ１の回りに、ブラケット３０と共に所定角度だけ回転移動する。 The bracket 30 has a drive projection 34 for rotationally driving the magnet 50 described above at a position spaced from the first rotation axis L1. The drive protrusion 34 rotates by a predetermined angle together with the bracket 30 around the first rotation axis L <b> 1 when the operation lever 10 is turned.
（ホルダ４０の構成）

（マグネット５０の構成）
マグネット５０は、例えば、フェライト系、ネオジム系、サマコバ系、サマリウム鉄窒素系等の磁性体材料と、ポリスチレン系、ポリエチレン系、ポリアミド系、アクリロニトリル／ブタジエン／スチレン（ＡＢＳ）等の合成樹脂材料と、を混合して所望の形状に成形したプラスチックマグネットである。なお、変形例として、回転部材は、例えば、マグネット５０と似た磁場を形成する電磁石等であっても良い。 (Configuration of magnet 50)
The magnet 50 is, for example, a magnetic material such as ferrite, neodymium, samakoba, and samarium iron nitrogen, and a synthetic resin material such as polystyrene, polyethylene, polyamide, acrylonitrile / butadiene / styrene (ABS), It is a plastic magnet formed by mixing and molding into a desired shape. As a modification, the rotating member may be, for example, an electromagnet that forms a magnetic field similar to the magnet 50.
マグネット５０は、図５Ａ～５Ｃに示されるように、円板部５１と、突出部５４と、円筒部５６と、を有する。このマグネット５０は、図５Ａに示されるように、マグネット５０の第３の回転軸Ｌ３に交差する方向に着磁され、突出部５４が設けられている一方がＳ極となり、他方がＮ極となっている。この着磁により、図５Ｂ及び図５Ｃに示されるように、磁束がマグネット５０のＮ極からＳ極に向かって放射され、Ｎ極から径方向に向かって放射された磁束がＳ極に収束される磁場５００を形成する。なお、着磁方向は、逆向きであっても良い。 As shown in FIGS. 5A to 5C, the magnet 50 includes a disc portion 51, a protruding portion 54, and a cylindrical portion 56. As shown in FIG. 5A, the magnet 50 is magnetized in a direction intersecting the third rotation axis L3 of the magnet 50, and one of the protrusions 54 provided is an S pole and the other is an N pole. It has become. 5B and 5C, the magnetic flux is radiated from the N pole of the magnet 50 toward the S pole, and the magnetic flux radiated from the N pole in the radial direction is converged on the S pole. The magnetic field 500 is formed. Note that the magnetization direction may be reversed.
円板部５１の上面５２には、円筒部５６が設けられ、下面５３には、傾斜５３０が設けられている。また、円板部５１には、側面からマグネット５０の径方向に突出するように突出部５４が設けられている。 A cylindrical portion 56 is provided on the upper surface 52 of the disc portion 51, and an inclination 530 is provided on the lower surface 53. The disk portion 51 is provided with a protruding portion 54 so as to protrude from the side surface in the radial direction of the magnet 50.
円筒部５６は、周方向に周溝部５６０が設けられている。この周溝部５６０は、上述のように、ホルダ４０の保持溝４２にスライド可能に嵌り込んでいる。ディマ操作が操作レバー１０になされた場合、操作レバー１０を介してホルダ４０がディマ操作の方向に従って上下に移動し、このホルダ４０の移動に伴って、保持溝４２に嵌るマグネット５０がホルダ４０と共に上下に移動する。なお、特に断らない限り、マグネット５０の上下の移動とは、図５Ｂの紙面の中立位置（Ｚ＝０）からの上方向（Ｄ位置：Ｚ＝＋１．５）及び下方向（Ｐ位置：Ｚ＝－１．５）の移動を示している。 The cylindrical portion 56 is provided with a circumferential groove portion 560 in the circumferential direction. As described above, the circumferential groove portion 560 is slidably fitted in the holding groove 42 of the holder 40. When the dimmer operation is performed on the operation lever 10, the holder 40 moves up and down according to the direction of the dimmer operation via the operation lever 10, and the magnet 50 that fits in the holding groove 42 is moved together with the holder 40 along with the movement of the holder 40. Move up and down. Unless otherwise specified, the vertical movement of the magnet 50 means upward (D position: Z = + 1.5) and downward (P position: Z) from the neutral position (Z = 0) in FIG. 5B. = -1.5).
また、マグネット５０は、円板部５１及び円筒部５６を貫通する貫通孔５７が設けられている。この貫通孔５７には、後述するマグネットホルダ７０のマグネット支持軸７２が挿入される。マグネット５０は、このマグネット支持軸７２を中心に回転する。 In addition, the magnet 50 is provided with a through hole 57 that penetrates the disc portion 51 and the cylindrical portion 56. A magnet support shaft 72 of a magnet holder 70 to be described later is inserted into the through hole 57. The magnet 50 rotates around the magnet support shaft 72.
突出部５４には、先端が開放されたＵ字形状の凹部５５が形成されている。この凹部５５には、ブラケット３０の駆動突起部３４が挿入されている。マグネット５０は、操作レバー１０になされたターン操作により、操作レバー１０を介してブラケット３０が矢印ＴＬ方向又は矢印ＴＲ方向に第１の回転軸Ｌ１を軸として回転すると、凹部５５に挿入された駆動突起部３４が第１の回転軸Ｌ１を中心とした円に沿って移動するので、貫通孔５７に挿入されたマグネット支持軸７２を第３の回転軸Ｌ３として回転する。 The protrusion 54 is formed with a U-shaped recess 55 having an open tip. The drive projection 34 of the bracket 30 is inserted into the recess 55. The magnet 50 is driven into the recess 55 when the bracket 30 rotates about the first rotation axis L1 in the direction of the arrow TL or the direction of the arrow TR via the operation lever 10 by the turning operation performed on the operation lever 10. Since the protrusion 34 moves along a circle centered on the first rotation axis L1, the magnet support shaft 72 inserted into the through hole 57 rotates as the third rotation axis L3.
また、マグネット５０は、予め定められた回転角θの範囲において、第１のディマ検出センサ９１及び第２のディマ検出センサ９２と対向する部分の厚さＴ１が、平面５０３に直交する平面５０４に対して第１のディマ検出センサ９１及び第２のディマ検出センサ９２と面対称となる配置面１０１上の位置に対向する部分の厚さＴ２よりも薄くなる形状を有している。 Further, the magnet 50 has a plane 504 in which the thickness T 1 of the portion facing the first dimmer detection sensor 91 and the second dimmer detection sensor 92 is orthogonal to the plane 503 in the range of the predetermined rotation angle θ. On the other hand, the first dimmer detection sensor 91 and the second dimmer detection sensor 92 have a shape that is thinner than the thickness T 2 of the portion facing the position on the arrangement surface 101 that is plane-symmetrical.
この予め定められた回転角θの範囲とは、操作レバー１０のターン操作に基づく、マグネット５０の回転範囲であり、一例として、４５°以上１３５°以下の範囲である。この厚さＴ１及び厚さＴ２の関係は、少なくとも当該範囲内で成り立つ。また、厚さＴ１は、一例として、厚さＴ２の半分の厚みとなっている。なお、操作レバー１０が中立位置にある際のマグネット５０の回転角θを９０°としている。 The predetermined range of the rotation angle θ is a rotation range of the magnet 50 based on the turning operation of the operation lever 10, and as an example, a range of 45 ° or more and 135 ° or less. The relationship between the thickness T 1 and the second thickness T 2 is satisfied in at least the range. In addition, the thickness T 1 is, for example, half the thickness T 2 . The rotation angle θ of the magnet 50 when the operation lever 10 is in the neutral position is 90 °.
この厚さＴ１及び厚さＴ２の関係を成立させるために、マグネット５０の下面５３には、傾斜５３０が形成されている。この傾斜５３０は、例えば、図６Ａ及び６Ｂに示されるように、下面５３のＮ極とＳ極との境界近傍から貫通孔５７に最も遠い側面に向かって傾斜するように形成されている。つまり、マグネット５０は、Ｓ極部分よりもＮ極部分の方が薄くなって、体積が小さくなっている。なお、厚さＴ１は、一例として、厚さＴ２の半分の厚みである。 In order to establish the relationship between the thickness T 1 and the thickness T 2 , an inclination 530 is formed on the lower surface 53 of the magnet 50. For example, as shown in FIGS. 6A and 6B, the inclination 530 is formed so as to incline toward the side surface farthest from the through hole 57 from the vicinity of the boundary between the N pole and the S pole of the lower surface 53. That is, the magnet 50 has a smaller volume at the N-pole portion than at the S-pole portion, resulting in a smaller volume. The thickness T 1 is, for example, half the thickness T 2 .
この傾斜５３０は、第１のディマ検出センサ９１及び第２のディマ検出センサ９２に作用する磁場５００の磁束密度を、傾斜がない場合の磁束密度よりも低くするために設けられている。つまり、傾斜５３０は、マグネット５０の回転がマグネット５０の上下移動の検出に与える影響を小さくするために設けられている。 This inclination 530 is provided in order to make the magnetic flux density of the magnetic field 500 acting on the first dimmer detection sensor 91 and the second dimmer detection sensor 92 lower than the magnetic flux density when there is no inclination. That is, the inclination 530 is provided to reduce the influence of the rotation of the magnet 50 on the detection of the vertical movement of the magnet 50.

マグネットホルダ７０は、基板１００に固定された状態で、下部筐体２２に位置決めされて固定される。マグネットホルダ７０は、底部７１、底部７１からマグネット５０の方向に向かって突設して形成されたマグネット支持軸７２、底部７１からマグネット５０の方向に向かって突設してマグネット支持軸７２と同心円状に形成された壁部７３等を有している。このマグネットホルダ７０は、樹脂（非磁性材料）により一体に形成されている。 (Configuration of magnet holder 70)

When the operation lever 10 is operated around the second rotation axis L2, the third support shaft 72 is provided. The magnet 50 is supported to move up and down along the rotation axis L3. The wall portion 73 is provided along the outer periphery of the magnet 50, but the magnet 50 is mainly supported by the magnet support shaft 72. As a modification, the lever switch device 1 has a configuration in which the through hole 57 of the magnet 50 and the magnet support shaft 72 of the magnet holder 70 are not formed, and the magnet 50 is supported by the wall portion 73 so as to be rotatable and vertically movable. It is good also as a structure made.
上記説明した操作レバー１０、筐体２０、ブラケット３０、ホルダ４０は、マグネット５０の近くに配置されるので、マグネットホルダ７０と同様に樹脂等の非磁性材料により形成されるのが好ましい。 Since the operation lever 10, the housing 20, the bracket 30, and the holder 40 described above are disposed near the magnet 50, it is preferable that the operation lever 10, the housing 20, the bracket 30, and the holder 40 be formed of a nonmagnetic material such as resin.
（ターン検出センサ８０の構成）
ターン検出センサ８０は、例えば、マグネット５０の回転に伴う磁場５００の変化を検出するホール素子及び磁気抵抗素子等の磁気検出素子を用いて構成されている。本実施の形態では、ホール素子を用いている。 (Configuration of turn detection sensor 80)
The turn detection sensor 80 is configured using, for example, a magnetic detection element such as a Hall element and a magnetoresistive element that detects a change in the magnetic field 500 accompanying the rotation of the magnet 50. In the present embodiment, a Hall element is used.
ターン検出センサ８０は、例えば、図６Ａ及び６Ｂに示されるように、第３の回転軸Ｌ３が検出面８００の中心を通るように基板１００の配置面１０１に配置される。この検出面８００とは、例えば、磁場５００の変化に反応する面である。 For example, as shown in FIGS. 6A and 6B, the turn detection sensor 80 is arranged on the arrangement surface 101 of the substrate 100 so that the third rotation axis L3 passes through the center of the detection surface 800. The detection surface 800 is a surface that reacts to a change in the magnetic field 500, for example.
ターン検出センサ８０は、例えば、信号を増幅する増幅部や信号を処理する処理部等を含んで１つのチップとしてパッケージされている場合、磁気検出素子がチップの中心以外の場所に配置される可能性がある。本実施の形態におけるターン検出センサ８０、第１のディマ検出センサ９１及び第２のディマ検出センサ９２は、チップの中心と検出面の中心とが一致しないとしている。 For example, when the turn detection sensor 80 is packaged as one chip including an amplification unit that amplifies a signal, a processing unit that processes a signal, and the like, the magnetic detection element can be arranged at a place other than the center of the chip. There is sex. In the turn detection sensor 80, the first dimmer detection sensor 91, and the second dimmer detection sensor 92 in the present embodiment, the center of the chip does not coincide with the center of the detection surface.
（第１のディマ検出センサ９１及び第２のディマ検出センサ９２の構成）
第１のディマ検出センサ９１及び第２のディマ検出センサ９２は、例えば、操作レバー１０になされたディマ操作に伴うマグネット５０と配置面１０１との接近及び離脱、つまり、図５Ｂの紙面上下方向のマグネット５０の移動に伴う磁場５００の変化を検出するホール素子及び磁気抵抗素子等の磁気検出素子を用いて構成されている。本実施の形態では、ホール素子を用いている。 (Configuration of the first dimmer detection sensor 91 and the second dimmer detection sensor 92)
The first dimmer detection sensor 91 and the second dimmer detection sensor 92 are, for example, the approach and separation between the magnet 50 and the arrangement surface 101 associated with the dimmer operation performed on the operation lever 10, that is, in the vertical direction of the paper surface of FIG. A magnetic detection element such as a Hall element and a magnetoresistive element that detects a change in the magnetic field 500 accompanying the movement of the magnet 50 is used. In the present embodiment, a Hall element is used.
第１のディマ検出センサ９１は、図６Ａに示されるように、第３の回転軸Ｌ３と配置面１０１との交点８０１を通る直線５０６と配置面１０１にマグネット５０を投影して得られる写像５０５の外周との交点９１１に、検出面９１０の中心が位置するように配置されている。 As shown in FIG. 6A, the first dimmer detection sensor 91 has a mapping 505 obtained by projecting the magnet 50 onto the straight line 506 passing through the intersection 801 between the third rotation axis L3 and the placement surface 101 and the placement surface 101. The center of the detection surface 910 is located at the intersection 911 with the outer periphery of the.
また、第２のディマ検出センサ９２は、図６Ａに示されるように、第３の回転軸Ｌ３と配置面１０１との交点８０１を通る直線５０７と写像５０５の外周との交点９２１に、検出面９２０の中心が位置するように配置されている。言い換えるなら、第２のディマ検出センサ９２は、図６Ａに示す平面５０３に対して第１のディマ検出センサ９１と面対称な位置に配置されている。つまり、直線５０６と平面５０３とのなす角と直線５０７と平面５０３とのなす角とは、同じである（配置角θ１）。なお、平面５０３は、第３の回転軸Ｌ３を含むと共に、相互に鏡像となるようにマグネット５０を分ける平面である。 Further, as shown in FIG. 6A, the second dimmer detection sensor 92 has a detection surface at the intersection 921 between the straight line 507 passing through the intersection 801 between the third rotation axis L3 and the arrangement surface 101 and the outer periphery of the mapping 505. It arrange | positions so that the center of 920 may be located. In other words, the second dimmer detection sensor 92 is disposed at a position symmetrical to the first dimmer detection sensor 91 with respect to the plane 503 shown in FIG. 6A. That is, the angle formed by the straight line 506 and the plane 503 is the same as the angle formed by the straight line 507 and the plane 503 (arrangement angle θ 1 ). The plane 503 is a plane that includes the third rotation axis L3 and separates the magnets 50 so as to be mirror images of each other.
第１のディマ検出センサ９１は、検出値Ｓ２を出力し、第２のディマ検出センサ９２は、検出値Ｓ３を出力する。第１のディマ検出センサ９１及び第２のディマ検出センサ９２は、検出値Ｓ２及び検出値Ｓ３の和が実質的に一定となるような配置角θ１となるように配置される。 First dimmer detection sensor 91 outputs a detection value S 2, the second dimmer detection sensor 92 outputs a detection value S 3. The first dimmer detection sensor 91 and the second dimmer detection sensor 92 are arranged so that the arrangement angle θ 1 is such that the sum of the detection value S 2 and the detection value S 3 is substantially constant.
マグネット５０は、例えば、図５Ｂに示されるように、操作レバー１０のディマ操作に応じて、３つの操作位置（Ｄ位置、中立位置、Ｐ位置）に移動する。マグネット５０は、例えば、操作レバー１０が矢印Ｄ方向に操作されると、中立位置（Ｚ＝０）から上方向（Ｄ位置）に移動する。この上方向の移動量は、一例として、＋１．５ｍｍである。また、マグネット５０は、例えば、操作レバー１０が矢印Ｐ方向に操作されると、中立位置から下方向（Ｐ位置）に移動する。この下方向の移動量は、一例として、?１．５ｍｍである。第１のディマ検出センサ９１及び第２のディマ検出センサ９２は、この３つの操作位置におけるマグネット５０の磁場５００の磁束密度を検出し、検出値Ｓ２及び検出値Ｓ３として制御部１５０に出力する。 For example, as shown in FIG. 5B, the magnet 50 moves to three operation positions (D position, neutral position, and P position) according to the dimmer operation of the operation lever 10. For example, when the operation lever 10 is operated in the arrow D direction, the magnet 50 moves from the neutral position (Z = 0) to the upward direction (D position). As an example, the upward movement amount is +1.5 mm. Further, for example, when the operation lever 10 is operated in the arrow P direction, the magnet 50 moves from the neutral position to the downward direction (P position). As an example, the downward movement amount is? 1.5 mm. First dimmer detection sensor 91 and the second dimmer detection sensor 92 detects the magnetic flux density of the magnetic field 500 of the magnet 50 in the three operating positions, output to the control unit 150 as a detection value S 2 and a detection value S 3 To do.
（制御部１５０の構成）
制御部１５０は、例えば、記憶されたプログラムに従って、取得したデータに演算、加工等を行うＣＰＵ（Central Processing Unit）、半導体メモリであるＲＡＭ（Random Access Memory）及びＲＯＭ（Read Only Memory）等から構成されるマイクロコンピュータである。このＲＯＭには、例えば、制御部１５０が動作するためのプログラムが格納されている。ＲＡＭは、例えば、一時的に演算結果等を格納する記憶領域として用いられる。 (Configuration of control unit 150)
The control unit 150 includes, for example, a CPU (Central Processing Unit) that performs operations and processing on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. For example, a program for operating the control unit 150 is stored in the ROM. For example, the RAM is used as a storage area for temporarily storing calculation results and the like.
制御部１５０は、図６Ｃに示されるように、ターン検出センサ８０、第１のディマ検出センサ９１及び第２のディマ検出センサ９２と接続されている。また、制御部１５０は、しきい値１５１を有している。 The controller 150 is connected to the turn detection sensor 80, the first dimmer detection sensor 91, and the second dimmer detection sensor 92, as shown in FIG. 6C. The control unit 150 has a threshold value 151.

また、制御部１５０は、第１のディマ検出センサ９１が出力した検出値Ｓ２と第２のディマ検出センサ９２が出力した検出値Ｓ３とを加算し、加算した加算値としきい値１５１とを比較し、ディマ操作による上述の３つの操作位置を検出するように構成されている。 The control unit 150, and a detection value S 3 in which the detected value S 2 of the first dimmer detection sensor 91 has output the second dimmer detection sensor 92 has output the sum, the sum and threshold values 151 obtained by adding And the above-mentioned three operation positions by the dimmer operation are detected.

Control unit 150, for example, operation information S 4 through the connector 110 provided on the substrate 100 is configured to output to the vehicle control unit of the vehicle 5.
（マグネット５０の傾斜５３０とディマ検出センサの配置について）
図７Ａは、実施の形態に係るレバースイッチ装置の右方向のターン操作によるマグネットの回転を示す上面図であり、図７Ｂは、レバーが中立位置にあるときのマグネットを示す上面図であり、図７Ｃは、左方向のターン操作によるマグネットの回転を示す上面図である。図７Ａ～７Ｃでは、紙面の上側から左回りに、マグネット５０の回転角θ２が０°～１８０°となるように示している。 (About the arrangement of the inclination 530 of the magnet 50 and the dimmer detection sensor)

図８Ａは、実施の形態に係る第１のディマ検出センサの検出値Ｓ２、第２のディマ検出センサの検出値Ｓ３、及び検出値Ｓ２と検出値Ｓ３を加算した加算値（Ｓ２＋Ｓ３）のを示すグラフであり、図８Ｂは、第１のディマ検出センサ及び第２のディマ検出センサによるディマ操作の検出を説明するためのグラフであり、図８Ｃは、第１のディマ検出センサ及び第２のディマ検出センサの配置角θ１と磁束密度の関係を示すグラフであり、図８Ｄは、比較例における検出値Ｓ２、検出値Ｓ３及び加算値（Ｓ２＋Ｓ３）を示すグラフである。図８Ａ、８Ｂ及び８Ｄは、縦軸が磁束密度（ｍＴ）であり、横軸がマグネット５０の回転角θ２（deg）である。図８Ｃは、左右の縦軸が磁束密度（ｍＴ）であり、横軸が配置角θ１（deg）である。また、図８Ｃは、左側の縦軸が磁束密度の差を図示するためのものであり、右側の縦軸が磁束密度の最大値の和を図示するためのものである。図８Ａ～８Ｄは、ＡＮＳＹＳ　Ｅｍａｇを用いてシミュレーションした結果を図示したものである。 FIG. 8A shows the detection value S 2 of the first dimmer detection sensor, the detection value S 3 of the second dimmer detection sensor according to the embodiment, and the added value obtained by adding the detection value S 2 and the detection value S 3 (S 2 + S 3 ), FIG. 8B is a graph for explaining the detection of the dimmer operation by the first dimmer detection sensor and the second dimmer detection sensor, and FIG. 8C is the first dimmer detection sensor. FIG. 8D is a graph showing the relationship between the arrangement angle θ 1 of the detection sensor and the second dimmer detection sensor and the magnetic flux density, and FIG. 8D shows the detection value S 2 , the detection value S 3 and the addition value (S 2 + S 3 ) in the comparative example. It is a graph which shows. 8A, 8B, and 8D, the vertical axis represents the magnetic flux density (mT), and the horizontal axis represents the rotation angle θ 2 (deg) of the magnet 50. In FIG. 8C, the left and right vertical axes are the magnetic flux density (mT), and the horizontal axis is the arrangement angle θ 1 (deg). 8C, the left vertical axis is for illustrating the difference in magnetic flux density, and the right vertical axis is for illustrating the sum of the maximum values of magnetic flux density. 8A to 8D illustrate the results of simulation using ANSYS Emag.
図８Ｄは、比較例として、傾斜が形成されていない円柱形状のマグネットの検出値Ｓ２、検出値Ｓ３及び加算値（Ｓ２＋Ｓ３）を示している。この比較例では、第１のディマ検出センサ９１及び第２のディマ検出センサ９２の配置は、図６Ａと同じであるものとする。 FIG. 8D shows a detection value S 2 , a detection value S 3, and an addition value (S 2 + S 3 ) of a cylindrical magnet with no inclination formed as a comparative example. In this comparative example, the arrangement of the first dimmer detection sensor 91 and the second dimmer detection sensor 92 is the same as that in FIG. 6A.
操作レバー１０が右方向（矢印ＴＲ方向）にターン操作されると、図７Ａに示されるように、第１のディマ検出センサ９１に対向するマグネットの部分は、Ｎ極の中心近傍となる。また、操作レバー１０が左方向（矢印ＴＬ方向）にターン操作されると、図７Ｃに示されるように、第１のディマ検出センサ９１に対向するマグネットの部分は、Ｎ極とＳ極の境界近傍となる。従って、第１のディマ検出センサ９１に作用する磁場の磁束密度は、回転角θ２が大きくなるにつれて高くなる。よって、検出値Ｓ２は、図８Ｄに示されるように、右肩上がりの曲線となる。なお、図８Ａ～８Ｄでは、磁束密度の符号を負としている。 When the operation lever 10 is turned rightward (arrow TR direction), as shown in FIG. 7A, the portion of the magnet facing the first dimmer detection sensor 91 is near the center of the N pole. Further, when the operation lever 10 is turned in the left direction (arrow TL direction), as shown in FIG. 7C, the magnet portion facing the first dimmer detection sensor 91 has a boundary between the N pole and the S pole. It becomes a neighborhood. Therefore, the magnetic flux density of the magnetic field acting on the first dimmer detection sensor 91 increases as the rotation angle θ 2 increases. Therefore, the detection value S 2, as shown in FIG. 8D, the soaring of the curve. In FIGS. 8A to 8D, the sign of the magnetic flux density is negative.
同様に、操作レバー１０が右方向（矢印ＴＲ方向）にターン操作されると、図７Ａに示されるように、第２のディマ検出センサ９２に対向するマグネットの部分は、Ｎ極とＳ極の境界近傍となる。また、操作レバー１０が左方向（矢印ＴＬ方向）にターン操作されると、図７Ｃに示されるように、第２のディマ検出センサ９２に対向するマグネットの部分は、Ｎ極の中心近傍となる。従って、第２のディマ検出センサ９２に作用する磁場の磁束密度は、第１のディマ検出センサ９１とは逆に、回転角θ２が大きくなるにつれて低くなる。よって、検出値Ｓ３は、図８Ｄに示されるように、左肩上がりの曲線となる。比較例では、検出値Ｓ２及び検出値Ｓ３の最大値と最小値の差の絶対値は、それぞれおよそ３６ｍＴである。なお、以下において、検出値Ｓ２及び検出値Ｓ３が正の場合は、絶対値を取る必要はない。 Similarly, when the operation lever 10 is turned to the right (arrow TR direction), as shown in FIG. 7A, the magnet portion facing the second dimmer detection sensor 92 has an N pole and an S pole. Near the boundary. When the operation lever 10 is turned leftward (in the direction of the arrow TL), as shown in FIG. 7C, the magnet portion facing the second dimmer detection sensor 92 is near the center of the N pole. . Accordingly, the magnetic flux density of the magnetic field acting on the second dimmer detection sensor 92 is lower as the rotation angle θ 2 is larger, contrary to the first dimmer detection sensor 91. Therefore, the detection value S 3, as shown in FIG. 8D, a steadily declining curve. In the comparative example, the absolute value of the difference between the maximum value and the minimum value of the detected value S 2 and a detection value S 3 is approximately 36mT, respectively. In the following, the detection value S 2 and a detection value S 3 for positive, no need to take the absolute value.
この検出値Ｓ２と検出値Ｓ３の和を計算すると、図８Ｄに示す加算値（Ｓ２＋Ｓ３）となる。この加算値は、最大値と最小値の差の絶対値が、およそ２０ｍＴとなっている。 When the sum of the detection value S 2 and the detection value S 3 is calculated, an addition value (S 2 + S 3 ) shown in FIG. 8D is obtained. This added value has an absolute value of the difference between the maximum value and the minimum value of approximately 20 mT.
ここで、マグネット５０に傾斜５３０が形成されている場合、図８Ａに示されるように、中立位置において、第１のディマ検出センサ９１の検出値Ｓ２、及び第２のディマ検出センサ９２の検出値Ｓ３の絶対値がおよそ３６ｍＴであり、比較例の検出値の絶対値がおよそ５５ｍＴであることから、傾斜５３０が形成されている方が、中立位置において検出される磁束密度が低くなっている。 Here, when the magnet 50 has an inclination 530, as shown in FIG. 8A, the detection value S 2 of the first dimmer detection sensor 91 and the detection of the second dimmer detection sensor 92 are detected at the neutral position. an absolute value of approximately 36mT value S 3, since the absolute value of the detected value of the comparative example is approximately 55MT, who inclined 530 is formed, is low flux density detected in the neutral position Yes.
また、マグネット５０が右方向及び左方向に回転しても、第１のディマ検出センサ９１及び第２のディマ検出センサ９２に対向する部分は、Ｓ極の部分よりも厚みが薄い、つまり、体積が小さいので、比較例と比べて、第１のディマ検出センサ９１及び第２のディマ検出センサ９２により検出される磁束密度が低い。従って、マグネット５０が回転してＮ極とＳ極との境界近傍にディマ検出センサが位置しても検出される磁束密度が比較例と比べて低くなり、図８Ａに示されるように、最大値と最小値の差の絶対値が小さくなる（およそ１０ｍＴ）。 Even when the magnet 50 rotates in the right direction and the left direction, the portions facing the first dimmer detection sensor 91 and the second dimmer detection sensor 92 are thinner than the S pole portion, that is, the volume. Therefore, the magnetic flux density detected by the first dimmer detection sensor 91 and the second dimmer detection sensor 92 is lower than that of the comparative example. Therefore, even if the dimmer detection sensor is positioned in the vicinity of the boundary between the N pole and the S pole as the magnet 50 rotates, the detected magnetic flux density is lower than that in the comparative example, and the maximum value is obtained as shown in FIG. 8A. And the absolute value of the difference between the minimum value and the minimum value becomes small (approximately 10 mT).
加算値（Ｓ２＋Ｓ３）の最大値と最小値の差の絶対値は、図８Ａに示されるように、およそ８ｍＴであり、比較例の差の絶対値（およそ２０ｍＴ）の半分以下となって、より直線に近くなっている。加算値（Ｓ２＋Ｓ３）の差が直線に近くなることは、第１のディマ検出センサ９１及び第２のディマ検出センサ９２に作用する磁場の磁束密度がマグネット５０の回転によって殆ど変化しない、つまり、マグネット５０の回転がディマ操作の検出に与える影響が小さいということを示している。従って、第１のディマ検出センサ９１及び第２のディマ検出センサ９２は、マグネット５０の回転に左右されることなく、ディマ操作によるマグネット５０の上下の移動を検出可能である。 As shown in FIG. 8A, the absolute value of the difference between the maximum value and the minimum value of the added value (S 2 + S 3 ) is approximately 8 mT, which is less than half of the absolute value of the difference of the comparative example (approximately 20 mT). Is closer to a straight line. That the difference of the added value (S 2 + S 3 ) is close to a straight line means that the magnetic flux density of the magnetic field acting on the first dimmer detection sensor 91 and the second dimmer detection sensor 92 hardly changes due to the rotation of the magnet 50. That is, the influence of rotation of the magnet 50 on the detection of the dimmer operation is small. Accordingly, the first dimmer detection sensor 91 and the second dimmer detection sensor 92 can detect the vertical movement of the magnet 50 due to the dimmer operation without being influenced by the rotation of the magnet 50.
図８Ｃは、磁束密度の最大値と最小値の差の絶対値、及び加算値の最大値の絶対値が、第１のディマ検出センサ９１及び第２のディマ検出センサ９２の配置角θ１によってどのように変化するのかを示したグラフである。なお、図８Ｃにおける「○」の記号は、マグネットに傾斜が形成されていない比較例における、磁束密度の最大値と最小値の差の絶対値（磁束max-min）であり、「△」の記号は、加算値（Ｓ２＋Ｓ３）の絶対値（Ｓ２＋Ｓ３max）である。また図８Ｃにおける「□」の記号は、マグネットに傾斜が形成された場合における、磁束密度の最大値と最小値の差の絶対値（磁束max-min）であり、「◇」の記号は、加算値（Ｓ２＋Ｓ３）の絶対値（Ｓ２＋Ｓ３max）である。 FIG. 8C shows that the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density and the absolute value of the maximum value of the addition value are determined by the arrangement angle θ 1 of the first dimmer detection sensor 91 and the second dimmer detection sensor 92. It is the graph which showed how it changes. The symbol “◯” in FIG. 8C is the absolute value (magnetic flux max-min) of the difference between the maximum value and the minimum value of the magnetic flux density in the comparative example in which the magnet is not tilted. The symbol is the absolute value (S 2 + S 3 max) of the added value (S 2 + S 3 ). The symbol “□” in FIG. 8C is the absolute value (magnetic flux max-min) of the difference between the maximum value and the minimum value of the magnetic flux density when the magnet is inclined, and the symbol “◇” It is the absolute value (S 2 + S 3 max) of the added value (S 2 + S 3 ).
マグネットに傾斜が形成されていない場合、配置角θ１が大きくなるに従って、磁束密度の最大値と最小値の差の絶対値、及び加算値（Ｓ２＋Ｓ３）の絶対値は、小さくなる。具体的には、磁束密度の最大値と最小値の差の絶対値の差は、およそ５ｍＴである。また、加算値の絶対値の差は、およそ３４ｍＴである。 When the magnet is not inclined, the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density and the absolute value of the added value (S 2 + S 3 ) decrease as the arrangement angle θ 1 increases. Specifically, the difference between the absolute values of the difference between the maximum value and the minimum value of the magnetic flux density is about 5 mT. The difference between the absolute values of the added values is approximately 34 mT.
一方、マグネットに傾斜が形成されている場合、配置角θ１が変化しても、磁束密度の最大値と最小値の差の絶対値、及び加算値（Ｓ２＋Ｓ３）の絶対値の変化は、僅かである。具体的には、磁束密度の最大値と最小値の差の絶対値の差は、およそ１ｍＴである。また、加算値の絶対値の差は、およそ７ｍＴである。つまり、磁束密度の最大値と最小値の差の絶対値、及び加算値（Ｓ２＋Ｓ３）の絶対値は、傾斜がある方が、比較例の五分の一程度の幅の中に収まっている。従って、傾斜がある方が、ディマ検出センサの配置のばらつきによる、磁束密度の最大値と最小値の差の絶対値、及び加算値（Ｓ２＋Ｓ３）の絶対値の変化を抑制する。 On the other hand, when the magnet is inclined, even if the arrangement angle θ 1 changes, the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density and the change in the absolute value of the added value (S 2 + S 3 ) are changed. Is slight. Specifically, the difference in absolute value between the maximum value and the minimum value of the magnetic flux density is approximately 1 mT. The difference between the absolute values of the added values is approximately 7 mT. That is, the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density and the absolute value of the added value (S 2 + S 3 ) are within the range of about one-fifth of the comparative example when there is a slope. ing. Therefore, when there is an inclination, changes in the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density and the absolute value of the added value (S 2 + S 3 ) due to variations in the arrangement of the dimmer detection sensors are suppressed.
つまり、傾斜５３０がマグネット５０に形成されることにより、第１のディマ検出センサ９１及び第２のディマ検出センサ９２の配置がばらついても、磁束密度の最大値と最小値の差の絶対値、及び加算値の最大値の絶対値のばらつきに与える影響が小さいことを示している。 That is, by forming the slope 530 in the magnet 50, the absolute value of the difference between the maximum value and the minimum value of the magnetic flux density, even if the arrangement of the first dimmer detection sensor 91 and the second dimmer detection sensor 92 varies, It shows that the influence on the variation in the absolute value of the maximum value of the addition value is small.
図８Ｂは、操作レバー１０のディマ操作による３つの操作位置に応じた磁束密度を示している。上述のように、加算値の最小値と最大値の絶対値の幅が狭い場合、図８Ｂに示されるように、操作位置に応じた加算値がマグネット５０の回転による影響を受けにくいので、操作位置を判定するためのしきい値１５１の設定が容易になると共に、しきい値１５１がばらついたとしても、正確な位置の判定が可能となる。 FIG. 8B shows magnetic flux densities corresponding to three operation positions by the dimmer operation of the operation lever 10. As described above, when the absolute value of the minimum value and the maximum value of the addition value is narrow, the addition value corresponding to the operation position is not easily affected by the rotation of the magnet 50 as shown in FIG. Setting of the threshold value 151 for determining the position is facilitated, and even if the threshold value 151 varies, the accurate position can be determined.

図９Ａにおいて、ターン操作により、操作レバー１０が矢印ＴＲ方向に操作されると、操作レバー１０は、第１の回転軸Ｌ１の回りに回転移動する。ブラケット３０は、操作レバー１０と一体となって回転し、駆動突起部３４も第１の回転軸Ｌ１の回りに回転移動する。マグネット５０は、凹部５５が駆動突起部３４に嵌合しているので、操作レバー１０の回転操作に伴って、マグネット支持軸７２（第３の回転軸Ｌ３）の回りに回転移動する。これにより、ターン検出センサ８０を通過する磁場５００の方向が変化する。 In FIG. 9A, when the operation lever 10 is operated in the direction of the arrow TR by a turn operation, the operation lever 10 rotates about the first rotation axis L1. The bracket 30 rotates integrally with the operation lever 10, and the drive protrusion 34 also rotates around the first rotation axis L1. Since the concave portion 55 is fitted to the drive protrusion 34, the magnet 50 rotates around the magnet support shaft 72 (third rotation axis L3) as the operation lever 10 rotates. As a result, the direction of the magnetic field 500 passing through the turn detection sensor 80 changes.
図９Ｂは、操作レバー１０が回転操作されていない中立時の位置状態を示す。この位置状態では、操作レバー１０、ブラケット３０は、回転していないので、マグネット５０も回転しない。これにより、ターン検出センサ８０を通過する磁場５００の方向は変化しない。 FIG. 9B shows a neutral position when the operation lever 10 is not rotated. In this position state, since the operation lever 10 and the bracket 30 are not rotated, the magnet 50 is not rotated either. As a result, the direction of the magnetic field 500 passing through the turn detection sensor 80 does not change.
図９Ｃにおいて、ターン操作により、操作レバー１０が矢印ＴＬ方向に操作されると、操作レバー１０は、第１の回転軸Ｌ１の回りに回転移動する。ブラケット３０は、操作レバー１０と一体となって回転し、駆動突起部３４も第１の回転軸Ｌ１の回りに回転移動する。マグネット５０は、凹部５５が駆動突起部３４に嵌合しているので、操作レバー１０の回転操作に伴って、マグネット支持軸７２（第３の回転軸Ｌ３）の回りに回転移動する。これにより、ターン検出センサ８０を通過する磁場５００の方向が変化する。なお、この磁場５００の方向の変化は、操作レバー１０の矢印ＴＲ方向への操作時と逆方向である。 In FIG. 9C, when the operation lever 10 is operated in the arrow TL direction by the turn operation, the operation lever 10 rotates around the first rotation axis L1. The bracket 30 rotates integrally with the operation lever 10, and the drive protrusion 34 also rotates around the first rotation axis L1. Since the concave portion 55 is fitted to the drive protrusion 34, the magnet 50 rotates around the magnet support shaft 72 (third rotation axis L3) as the operation lever 10 rotates. As a result, the direction of the magnetic field 500 passing through the turn detection sensor 80 changes. Note that the change in the direction of the magnetic field 500 is opposite to that when the operation lever 10 is operated in the arrow TR direction.
（ディマ操作について）
図１０Ａは、図２のＡ－Ａ断面において、矢印Ｄ方向のディマ操作時の操作レバー、マグネットの移動状態を示す部分断面図であり、図１０Ｂは、図２のＡ－Ａ断面において、中立時の操作レバー、マグネットの移動状態を示す部分断面図であり、図１０Ｃは、図２のＡ－Ａ断面において、矢印Ｐ方向のディマ操作時の操作レバー、マグネットの移動状態を示す部分断面図である。 (Dima operation)
10A is a partial cross-sectional view showing a moving state of the operation lever and the magnet during the dimmer operation in the direction of arrow D in the AA cross section of FIG. 2, and FIG. 10B is a neutral view in the AA cross section of FIG. FIG. 10C is a partial cross-sectional view showing the moving state of the operating lever and the magnet during the dimmer operation in the direction of arrow P in the AA cross section of FIG. It is.
図１０Ａにおいて、ディマ操作により、操作レバー１０が矢印Ｄ方向に操作されると、操作レバー１０は第２の回転軸Ｌ２の回りに回転移動する。ホルダ４０は、操作レバー１０の駆動突起部１４が上方向に移動することから、この駆動突起部１４に嵌合する嵌合溝４１を介して上方向にスライド移動する。ホルダ４０の保持溝４２で保持されているマグネット５０は、マグネット支持軸７２に支持されて上方向にスライド移動する。これにより、マグネット５０の下方に配置された第１のディマ検出センサ９１及び第２のディマ検出センサ９２を通過する磁場５００の磁束密度が変化する。この操作レバー１０の位置でターン操作した場合の加算値（Ｓ２＋Ｓ３）は、一例として、図８Ｂに実線で示される。 In FIG. 10A, when the operating lever 10 is operated in the direction of arrow D by a dimmer operation, the operating lever 10 rotates around the second rotation axis L2. Since the drive protrusion 14 of the operation lever 10 moves upward, the holder 40 slides upward via the fitting groove 41 that fits into the drive protrusion 14. The magnet 50 held in the holding groove 42 of the holder 40 is supported by the magnet support shaft 72 and slides upward. As a result, the magnetic flux density of the magnetic field 500 that passes through the first dimmer detection sensor 91 and the second dimmer detection sensor 92 disposed below the magnet 50 changes. The added value (S 2 + S 3 ) when the turn is operated at the position of the operation lever 10 is shown by a solid line in FIG. 8B as an example.
図１０Ｂは、操作レバー１０が回転操作されていない中立時の位置状態を示す。この状態では、操作レバー１０は回転せず、また、ホルダ４０はスライド移動していないので、マグネット５０もスライド移動しない。これにより、マグネット５０の下方に配置された第１のディマ検出センサ９１及び第２のディマ検出センサ９２を通過する磁場５００の磁束密度は、変化しない。この操作レバー１０の位置でターン操作した場合の加算値（Ｓ２＋Ｓ３）は、一例として、図８Ｂに点線で示される。 FIG. 10B shows a neutral position when the operation lever 10 is not rotated. In this state, the operation lever 10 does not rotate, and the holder 40 does not slide, so the magnet 50 does not slide. As a result, the magnetic flux density of the magnetic field 500 that passes through the first dimmer detection sensor 91 and the second dimmer detection sensor 92 disposed below the magnet 50 does not change. The added value (S 2 + S 3 ) when the turn is operated at the position of the operation lever 10 is indicated by a dotted line in FIG. 8B as an example.
図１０Ｃにおいて、ディマ操作により、操作レバー１０が矢印Ｐ方向に操作されると、操作レバー１０は第２の回転軸Ｌ２の回りに回転移動する。ホルダ４０は、操作レバー１０の駆動突起部１４が下方向に移動することから、この駆動突起部１４に嵌合する嵌合溝４１を介して下方向にスライド移動する。ホルダ４０の保持溝４２で保持されているマグネット５０は、マグネット支持軸７２に支持されて下方向にスライド移動する。これにより、マグネット５０の下方に配置された第１のディマ検出センサ９１及び第２のディマ検出センサ９２を通過する磁場５００の磁束密度が変化する。この操作レバー１０の位置でターン操作した場合の加算値（Ｓ２＋Ｓ３）は、一例として、図８Ｂに一点鎖線で示される。 In FIG. 10C, when the operation lever 10 is operated in the direction of the arrow P by a dimmer operation, the operation lever 10 rotates around the second rotation axis L2. Since the drive protrusion 14 of the operation lever 10 moves downward, the holder 40 slides downward through the fitting groove 41 that is fitted to the drive protrusion 14. The magnet 50 held in the holding groove 42 of the holder 40 is supported by the magnet support shaft 72 and slides downward. As a result, the magnetic flux density of the magnetic field 500 that passes through the first dimmer detection sensor 91 and the second dimmer detection sensor 92 disposed below the magnet 50 changes. The added value (S 2 + S 3 ) when the turn is operated at the position of the operation lever 10 is indicated by a one-dot chain line in FIG. 8B as an example.
（実施の形態の効果）
本実施の形態に係るレバースイッチ装置１は、１つの磁石で２方向の動きを非接触で検出できる。具体的には、レバースイッチ装置１は、操作レバー１０のターン操作によりマグネット５０が第３の回転軸Ｌ３の周りを回転すると共に、操作レバー１０のディマ操作によりマグネット５０が第３の回転軸Ｌ３に沿って移動するように構成されている。また、レバースイッチ装置１は、マグネット５０の回転をターン検出センサ８０で検出し、マグネット５０の上下移動を第１のディマ検出センサ９１及び第２のディマ検出センサ９２で検出する。従って、レバースイッチ装置１は、１つの磁石で、ターン操作及びディマ操作の２方向の動きを非接触で検出できる。 (Effect of embodiment)
The lever switch device 1 according to the present embodiment can detect movement in two directions in a non-contact manner with one magnet. Specifically, in the lever switch device 1, the magnet 50 rotates around the third rotation axis L3 by the turning operation of the operation lever 10, and the magnet 50 is rotated by the third rotation axis L3 by the dimmer operation of the operation lever 10. It is comprised so that it may move along. Further, the lever switch device 1 detects the rotation of the magnet 50 with the turn detection sensor 80, and detects the vertical movement of the magnet 50 with the first dimmer detection sensor 91 and the second dimmer detection sensor 92. Therefore, the lever switch device 1 can detect the movement in the two directions of the turn operation and the dimmer operation in a non-contact manner with one magnet.
レバースイッチ装置１は、第１のディマ検出センサ９１及び第２のディマ検出センサ９２の検出値Ｓ２及び検出値Ｓ３の和が一定となるように配置されるので、マグネットの回転の影響が抑制され、精度の良い検出ができる。 Lever switch device 1 is the sum of the detected value S 2 and a detection value S 3 of the first dimmer detection sensor 91 and the second dimmer detection sensor 92 is arranged so as to be constant, the influence of rotation of the magnet Suppressed and accurate detection is possible.
レバースイッチ装置１は、第１のディマ検出センサ９１及び第２のディマ検出センサ９２が、マグネット５０を配置面１０１に投影した写像５０５に、検出面９１０及び検出面９２０の中心が位置するように配置されるので、検出面の中心が位置しない場合と比べて、効率的に磁束密度の変化を検出することができる。 The lever switch device 1 is configured so that the centers of the detection surface 910 and the detection surface 920 are positioned on the mapping 505 in which the first dimmer detection sensor 91 and the second dimmer detection sensor 92 project the magnet 50 onto the arrangement surface 101. Since it is arranged, a change in magnetic flux density can be detected more efficiently than when the center of the detection surface is not located.
レバースイッチ装置１は、マグネット５０が傾斜５３０を有している。マグネット５０は、傾斜５３０を有することで、第１のディマ検出センサ９１及び第２のディマ検出センサ９２に作用する磁場５００の磁束密度を、傾斜５３０が形成された部分の反対側の下方の磁束密度よりも低くすることができるので、ディマ操作の検出において、マグネット５０の回転の影響を受け難く、精度の良い検出ができる。 In the lever switch device 1, the magnet 50 has an inclination 530. Since the magnet 50 has the inclination 530, the magnetic flux density of the magnetic field 500 acting on the first dimmer detection sensor 91 and the second dimmer detection sensor 92 is changed to the lower magnetic flux on the opposite side of the portion where the inclination 530 is formed. Since the density can be made lower than the density, the detection of the dimmer operation is hardly affected by the rotation of the magnet 50 and can be detected with high accuracy.
レバースイッチ装置１は、ターン検出センサ８０、第１のディマ検出センサ９１及び第２のディマ検出センサ９２が基板１００の同じ配置面１０１に配置されているので、マグネットの側面から上下位置を検出する場合と比べて、マグネット５０とターン検出センサ８０、第１のディマ検出センサ９１及び第２のディマ検出センサ９２との位置決めが容易である。 In the lever switch device 1, the turn detection sensor 80, the first dimmer detection sensor 91, and the second dimmer detection sensor 92 are arranged on the same arrangement surface 101 of the substrate 100. Compared to the case, the positioning of the magnet 50, the turn detection sensor 80, the first dimmer detection sensor 91, and the second dimmer detection sensor 92 is easy.
ここで、変形例として、マグネット５０は、傾斜５３０が膨らむ、又は凹んでいても良く、また、第１のディマ検出センサ９１及び第２のディマ検出センサ９２に対向する部分近傍のみに形成されても良い。また、他の変形例として、マグネット５０は、回転に伴って、常にディマ検出センサ９０に対向する部分の厚さＴ１が厚さＴ２よりも薄く形成され、磁束密度が厚さＴ２の部分よりも低くなる形状であれば良い。 Here, as a modification, the magnet 50 may have an inclining 530 that is bulged or recessed, and is formed only in the vicinity of a portion that faces the first dimmer detection sensor 91 and the second dimmer detection sensor 92. Also good. Further, as another modified example, the magnet 50, with rotation, always formed thinner than dimmer detection sensor 90 of the opposing portions to the thickness T 1 is the second thickness T 2, the magnetic flux density of the second thickness T 2 Any shape that is lower than the portion may be used.
