　本発明の一実施形態に係る発光装置を、図面を参照して説明する。 A light emitting device according to an embodiment of the present invention will be described with reference to the drawings.
　本発明の一実施形態に係る発光装置は、図１に示す複合計器１に含まれる。複合計器１は、例えばハイブリット車などの車両に搭載され、車両に関する計測量をユーザ（主に運転者）に報知する。複合計器１は、例えば、車両のハンドル前方に配設される。 A light emitting device according to an embodiment of the present invention is included in a composite instrument 1 shown in FIG. The composite instrument 1 is mounted on a vehicle such as a hybrid car, for example, and notifies a user (mainly a driver) of a measurement amount related to the vehicle. The composite instrument 1 is disposed, for example, in front of a vehicle handle.
　以下では、構成の理解を容易にするために、複合計器１を正面視したときの手前側を「表」とし、奥側を「裏」として各部を説明する。 Hereinafter, in order to facilitate understanding of the configuration, each part will be described with the front side when the composite instrument 1 is viewed from the front as “front” and the back side as “back”.
　複合計器１は、図１に示すように、指針式計器２と、スピードメータ３と、ディスプレイ４とを備える。 As shown in FIG. 1, the composite instrument 1 includes a pointer-type instrument 2, a speedometer 3, and a display 4.
　指針式計器２は、指針２ａの指示箇所に応じて、車両のモータによるチャージ量及びアシスト量を報知するチャージ／アシストゲージとして機能する。指針２ａ、後述の指標部３１を指示する指示部２ｂと、指針２ａの回転中心部に設けられた指針キャップ２ｃと、を有する。指示部２ｂは、導光材からなり、後述の指針用光源１３からの光により発光可能となっている。指針キャップ２ｃは、遮光性を有し、指示部２ｂの回転中心部を表側から覆う。指針２ａは、軸線ＡＸを中心に、第１の範囲Ｒ１及び第２の範囲Ｒ２に渡って回転可能に構成されている。指針式計器２は、指針２ａが第１の範囲Ｒ１と第２の範囲Ｒ２の境界であるゲージ中間位置Ｎにあるときは、チャージ量とアシスト量がともに無い（ゼロである）状態を示す。 The pointer-type meter 2 functions as a charge / assist gauge that notifies the charge amount and the assist amount by the motor of the vehicle according to the point indicated by the pointer 2a. It has a pointer 2a, an instruction portion 2b that instructs a later-described indicator portion 31, and a pointer cap 2c provided at the center of rotation of the pointer 2a. The instruction unit 2b is made of a light guide material and can emit light by light from a pointer light source 13 described later. The pointer cap 2c has a light shielding property and covers the rotation center portion of the instruction portion 2b from the front side. The pointer 2a is configured to be rotatable around the axis AX over the first range R1 and the second range R2. When the pointer 2a is at the gauge intermediate position N that is the boundary between the first range R1 and the second range R2, the pointer-type meter 2 shows a state where neither the charge amount nor the assist amount is present (zero).
　指針２ａがゲージ中間位置Ｎよりも反時計回りに振れた場合は、第１の範囲Ｒ１におけるゲージ中間位置Ｎからの指針２ａの指示位置の割合によって、指針式計器２はアシスト量を報知する。つまり、指針２ａがゲージ中間位置Ｎよりも反時計回りに移動すればするほど、報知対象のアシスト量が増加する。一方、指針２ａがゲージ中間位置Ｎよりも時計回りに振れた場合は、第２の範囲Ｒ２におけるゲージ中間位置Ｎからの指針２ａの指示位置の割合によって、指針式計器２はチャージ量を報知する。つまり、指針２ａがゲージ中間位置Ｎよりも時計回りに移動すればするほど、報知対象のチャージ量が増加する。 When the pointer 2a swings counterclockwise from the gauge intermediate position N, the pointer-type meter 2 reports the assist amount according to the ratio of the indicated position of the pointer 2a from the gauge intermediate position N in the first range R1. That is, the more the pointer 2a moves counterclockwise than the gauge intermediate position N, the more the assist amount to be notified. On the other hand, when the pointer 2a swings clockwise from the gauge intermediate position N, the pointer-type meter 2 reports the charge amount according to the ratio of the indicated position of the pointer 2a from the gauge intermediate position N in the second range R2. . That is, the more the pointer 2a moves in the clockwise direction from the gauge intermediate position N, the more the charge amount to be notified increases.
　また、指針式計器２は、後述の発光表示部３１ａにより、軸線ＡＸを中心とした円周方向に沿って円弧状に延びる帯状光を視認させる。具体的には、指針式計器２は、第１の範囲Ｒ１においては、ゲージ中間位置Ｎから指針２ａの指示箇所にわたって円弧状に延びる第１帯状光Ｌ１（図５参照）を発光表示する。また、指針式計器２は、図１に示すように、第２の範囲Ｒ２においては、ゲージ中間位置Ｎから指針２ａの指示箇所にわたって円弧状に延びる第２帯状光Ｌ２を発光表示する。このように、指針式計器２は、指針２ａの移動に応じてゲージ中間位置Ｎから円弧状に延びる第１帯状光Ｌ１又は第２帯状光Ｌ２を発光表示する発光装置を含み、斬新で見栄えの良い表示を実現する。なお、後述するように、指針２ａが丁度、ゲージ中間位置Ｎに位置した際には、第１帯状光Ｌ１及び第２帯状光Ｌ２は視認されないことになる。また、指針式計器２は、後述の燃料表示部３２により車両の残燃料を報知する。 Further, the pointer-type meter 2 causes the light-emitting display unit 31a described later to visually recognize the strip-shaped light that extends in an arc shape along the circumferential direction around the axis AX. Specifically, in the first range R1, the pointer-type meter 2 emits and displays the first strip light L1 (see FIG. 5) that extends in an arc shape from the gauge intermediate position N to the indicated position of the pointer 2a. In addition, as shown in FIG. 1, the pointer-type meter 2 emits and displays the second strip light L2 extending in an arc shape from the gauge intermediate position N to the point indicated by the pointer 2a in the second range R2. As described above, the pointer-type meter 2 includes a light emitting device that emits and displays the first strip light L1 or the second strip light L2 that extends in an arc shape from the gauge intermediate position N according to the movement of the pointer 2a, and is novel and attractive. Realize good display. As will be described later, when the pointer 2a is positioned at the gauge intermediate position N, the first strip light L1 and the second strip light L2 are not visually recognized. Further, the pointer-type meter 2 notifies the remaining fuel of the vehicle by a fuel display unit 32 described later.
　スピードメータ３は、図１に示すように指針式計器２の左隣りに設けられ、指針３ａの指示箇所に応じて、車速を報知する。ディスプレイ４は、指針式計器２及びスピードメータ３の一部（指針２ａ及び指針３ａの各々の回転中心部近傍）を表側から覆うように設けられ、車両に関する各種情報を画像により報知する。ディスプレイ４は、ＬＣＤ（Liquid Crystal Display）、ＯＬＥＤ（Organic Light Emitting Diode）などから構成されてい
る。 As shown in FIG. 1, the speedometer 3 is provided on the left side of the pointer-type meter 2 and notifies the vehicle speed according to the point indicated by the pointer 3 a. The display 4 is provided so as to cover a part of the pointer-type meter 2 and the speedometer 3 (near the rotation center of each of the pointer 2a and the pointer 3a) from the front side, and notifies various information about the vehicle by an image. The display 4 includes an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode), and the like.
　以下では、複合計器１の構成のうち、発光装置を含む指針式計器２に関連する構成を中心に説明する。 Below, it demonstrates centering on the structure relevant to the pointer type | mold instrument 2 containing a light-emitting device among the structures of the composite instrument 1. FIG.
　複合計器１は、図２に示す回路基板１０、インナーケース２０、板部３０、及び発光用部品群１００と、図５及び図６に示すリアケース４０と、を備える。また、複合計器１は、図示しないレンズと見返し部材を、板部３０よりも表側に備える。 The composite instrument 1 includes a circuit board 10, an inner case 20, a plate portion 30, and a light emitting component group 100 shown in FIG. 2, and a rear case 40 shown in FIGS. 5 and 6.

　回路基板１０は、各種回路が形成されたプリント回路板から構成されている。回路基板１０に実装されるか、回路基板１０と電気的に接続される制御部（図示せず）によって、複合計器１の全体動作が制御される。回路基板１０は、図５及び図６に示すように、リアケース４０の表側に位置する。回路基板１０の裏側には、指針２ａを回転させるためのモータ１１が実装されている。モータ１１は、例えばステッピングモータから構成されている。モータ１１の回転軸１１ａは、回路基板１０の基材を貫通して回路基板１０の表側へと突出している。回転軸１１ａの先端部に指針２ａが取り付けられていることにより、モータ１１の動作に伴い指針２ａが軸線ＡＸを中心に回転可能となっている。回路基板１０と電気的に接続された制御部は、車両のＥＣＵ（Electronic Control Unit）から取得したチャージ量及びアシスト量に応じて、モータ１１を介し、指針２ａを回転させる。 The circuit board 10 is composed of a printed circuit board on which various circuits are formed. The overall operation of the composite instrument 1 is controlled by a control unit (not shown) mounted on the circuit board 10 or electrically connected to the circuit board 10. As shown in FIGS. 5 and 6, the circuit board 10 is located on the front side of the rear case 40. A motor 11 for rotating the pointer 2 a is mounted on the back side of the circuit board 10. The motor 11 is composed of a stepping motor, for example. The rotating shaft 11 a of the motor 11 passes through the base material of the circuit board 10 and projects to the front side of the circuit board 10. By attaching the pointer 2a to the tip of the rotating shaft 11a, the pointer 2a can rotate around the axis AX as the motor 11 operates. A control unit electrically connected to the circuit board 10 rotates the pointer 2a via the motor 11 according to the charge amount and the assist amount acquired from the ECU (Electronic Control Unit) of the vehicle.
　回路基板１０の表側には、後述の発光表示部３１ａを発光させるための光源１２が実装されている。また、回路基板１０の表側には、指針２ａを発光させるための指針用光源１３も実装されている。光源１２と指針用光源１３の各々は、例えば、ＬＥＤ（Light Emitting Diode）から構成されている。光源１２は、例えば複数あり、指針２ａの回転範囲に概ね対応して、図２に示すように回転軸１１ａを中心に円弧状に配列されている。指針用光源１３は、例えば複数あり、光源１２よりも回転軸１１ａの近傍に配列されている。 On the front side of the circuit board 10, a light source 12 for causing a light emitting display unit 31a described later to emit light is mounted. A pointer light source 13 for causing the pointer 2 a to emit light is also mounted on the front side of the circuit board 10. Each of the light source 12 and the pointer light source 13 is composed of, for example, an LED (Light Emitting Diode). There are a plurality of light sources 12, for example, and they are arranged in an arc shape around the rotation shaft 11a as shown in FIG. 2 so as to substantially correspond to the rotation range of the pointer 2a. There are a plurality of pointer light sources 13, for example, and they are arranged closer to the rotating shaft 11 a than the light sources 12.
　発光表示部３１ａを発光させるための光源１２は、例えば、複合計器１の起動中においては常時点灯している。この実施形態では、複数の光源１２の点灯を個別に制御することによってではなく、後述する発光用部品群１００などの機械的要素により、第１帯状光Ｌ１及び第２帯状光Ｌ２を、指針２ａの回転に追従するように発光させる。 The light source 12 for causing the light emitting display unit 31a to emit light is always lit while the composite instrument 1 is activated, for example. In this embodiment, the lighting of the first strip light L1 and the second strip light L2 is not performed by individually controlling lighting of the plurality of light sources 12, but by mechanical elements such as the light emitting component group 100 described later. The light is emitted so as to follow the rotation.
　インナーケース２０は、図５及び図６に示すように、リアケース４０に表側から嵌め合わされ、リアケース４０と共に各種部品を収納する。インナーケース２０は、裏側において回路基板１０を保持し、表側において板部３０を保持している。なお、インナーケース２０は、表側においてディスプレイ４なども保持している。インナーケース２０は、板部３０と回路基板１０との間に位置している。 As shown in FIGS. 5 and 6, the inner case 20 is fitted into the rear case 40 from the front side and accommodates various components together with the rear case 40. The inner case 20 holds the circuit board 10 on the back side and holds the plate part 30 on the front side. The inner case 20 also holds the display 4 and the like on the front side. The inner case 20 is located between the plate portion 30 and the circuit board 10.
　インナーケース２０には、図２に示すように、軸線ＡＸを中心とした略円形の孔２０ａが設けられている。このように設けられた孔２０ａによって、発光用部品群１００の配設スペースが確保されている。 As shown in FIG. 2, the inner case 20 is provided with a substantially circular hole 20a centered on the axis AX. An arrangement space for the light emitting component group 100 is secured by the holes 20a thus provided.
　また、インナーケース２０には、孔２０ａを囲むようにして、図４に示すように、円弧状の仕切り部２１が形成されている。仕切り部２１は、回転軸１１ａの円周方向に沿って配列された複数の仕切りを有する。当該複数の仕切りによって、仕切り部２１には、円周方向に沿って配列された複数のセグメント２２が形成される。これらセグメント２２により、帯状光（第１帯状光Ｌ１及び第２帯状光Ｌ２）の発光範囲が規定される。 Further, the inner case 20 is formed with an arc-shaped partition portion 21 as shown in FIG. 4 so as to surround the hole 20a. The partition part 21 has a plurality of partitions arranged along the circumferential direction of the rotating shaft 11a. By the plurality of partitions, a plurality of segments 22 arranged along the circumferential direction are formed in the partition portion 21. These segments 22 define the light emission range of the strip light (the first strip light L1 and the second strip light L2).
　各セグメント２２には、光源１２から発せられた後に、発光用部品群１００を介して、回転軸１１ａの外径方向に出射された光を、表側に向けて効率良く反射させる斜面２２ａが形成されている。このため、インナーケース２０は、反射効率の良い白色に所定の樹脂材から形成されている。なお、インナーケース２０において、少なくとも斜面２２ａに反射率の高い塗装を施すなどしても良い。 Each segment 22 is formed with an inclined surface 22a that efficiently reflects the light emitted from the light source 12 and then emitted in the outer diameter direction of the rotating shaft 11a toward the front side through the light emitting component group 100. ing. For this reason, the inner case 20 is formed of a predetermined resin material in a white color with good reflection efficiency. In the inner case 20, at least the slope 22 a may be painted with a high reflectance.
　板部３０は、図２に示すように、指針２ａに指示される指標部３１と、燃料表示部３２とを有する。板部３０は、インナーケース２０の表側に設けられている。板部３０は、例えば、ポリカーボネート等の透光性板材の表面と裏面との少なくとも一方に印刷層を形成したものであり、板材の広範囲に渡って遮光性印刷層が形成されている。板部３０は、軸線ＡＸを中心とした略円形の開口部３０ａを有する。この開口部３０ａによって、回転軸１１ａに取り付けられた指針２ａは、板部３０の表側において回転することが可能となっている。 As shown in FIG. 2, the plate part 30 includes an index part 31 indicated by the pointer 2 a and a fuel display part 32. The plate part 30 is provided on the front side of the inner case 20. The plate part 30 is formed by forming a printing layer on at least one of the front surface and the back surface of a translucent plate material such as polycarbonate, and a light-shielding printing layer is formed over a wide range of the plate material. The plate part 30 has a substantially circular opening 30a centered on the axis AX. Through this opening 30 a, the pointer 2 a attached to the rotation shaft 11 a can be rotated on the front side of the plate portion 30.
　板部３０の指標部３１は、発光表示部３１ａと、意匠部３１ｂと、を有する。 The indicator part 31 of the plate part 30 has a light emitting display part 31a and a design part 31b.
　発光表示部３１ａは、インナーケース２０の仕切り部２１に対応して円弧状に形成されている。発光表示部３１ａは、仕切り部２１の各セグメント２２に対応して、回転軸１１ａの円周方向に沿って配列された複数の透過窓３１ｃを有する。これら透過窓３１ｃは、板部３０において遮光性印刷層が施されていない部分により形成され、透光性を有している。これにより、１つの透過窓３１ｃは、当該透過窓３１ｃに対応する１つのセグメント２２の斜面２２ａで反射し、表側に向かう光を透過させることができる。 The light emitting display part 31 a is formed in an arc shape corresponding to the partition part 21 of the inner case 20. The light emitting display part 31a has a plurality of transmission windows 31c arranged along the circumferential direction of the rotating shaft 11a corresponding to each segment 22 of the partition part 21. These transmissive windows 31c are formed by portions of the plate portion 30 where the light-shielding print layer is not applied, and have translucency. Thereby, the one transmission window 31c can reflect on the inclined surface 22a of the one segment 22 corresponding to the transmission window 31c and transmit the light toward the front side.
　意匠部３１ｂは、例えば印刷層により形成され、文字、図形、記号などから構成されている。この実施形態に係る意匠部３１ｂは、発光表示部３１ａの役割を示すために設けられ、車両のモータによるアシスト量を示す「ＰＯＷＥＲ」という文字と、チャージ量を示す「ＣＨＡＲＧＥ」という文字と、指針２ａの回転範囲を示すとともに「ＰＯＷＥＲ」と「ＣＨＡＲＧＥ」の境界を示す略円弧状の図形とを有している。 The design portion 31b is formed of, for example, a printing layer, and includes characters, figures, symbols, and the like. The design portion 31b according to this embodiment is provided to indicate the role of the light emitting display portion 31a, and includes letters “POWER” indicating the amount of assist by the motor of the vehicle, characters “CHARGE” indicating the amount of charge, and pointers It has a rotation range of 2a and a substantially arc-shaped figure indicating the boundary between “POWER” and “CHARGE”.
　燃料表示部３２は、車両の残燃料をバーグラフ状の発光により報知する。燃料表示部３２は、例えば、板部３０において遮光性印刷層が施されていない部分により形成され、透光性を有している。これにより、回路基板１０に実装された燃料表示用の光源により発光可能となっている。 The fuel display unit 32 notifies the remaining fuel of the vehicle by light emission in the form of a bar graph. The fuel display part 32 is formed of, for example, a part of the plate part 30 where the light-shielding print layer is not applied, and has a light-transmitting property. As a result, light can be emitted from the light source for fuel display mounted on the circuit board 10.
　発光用部品群１００は、図３に示すように、導光体１１０と、ガイドケース１２０と、遮光キャップ１３０と、導光部１４０と、を備える。 As shown in FIG. 3, the light emitting component group 100 includes a light guide 110, a guide case 120, a light shielding cap 130, and a light guide unit 140.
　導光体１１０は、光源１２から受けた光を内部に導き、回転軸１１ａの外径方向に向かって出射する。導光体１１０は、例えばアクリル樹脂などによって透明に形成された導光部材である。導光体１１０は、指針用光源１３からの光を指針２ａに向けて導く導光部分とともに一体で成形されている。なお、導光体１１０は、当該導光部分と別体であってもよい。導光体１１０は、例えば、回路基板１０の基材に公知の手法で固定されている。 The light guide 110 guides the light received from the light source 12 to the inside and emits the light toward the outer diameter direction of the rotating shaft 11a. The light guide 110 is a light guide member that is formed transparent, for example, with acrylic resin. The light guide 110 is integrally formed with a light guide portion that guides light from the pointer light source 13 toward the pointer 2a. The light guide 110 may be a separate body from the light guide portion. The light guide 110 is fixed to the base material of the circuit board 10 by a known method, for example.
　導光体１１０は、図３に示すように、光源１２からの受けた光を回転軸１１ａの外径方向へと出射する出射部１１２を備える。具体的には、出射部１１２は、第１の範囲Ｒ１に対応して形成された第１出射部１１２ａと、第２の範囲Ｒ２に対応して形成された第２出射部１１２ｂと、を有する。つまり、第１出射部１１２ａと第２出射部１１２ｂとは、回転軸１１ａの円周方向においてゲージ中間位置Ｎを境に隣り合うように位置する。図５に示すように、第１出射部１１２ａから出射された光が第１帯状光Ｌ１となる。図６に示すように、第２出射部１１２ｂから出射された光が第２帯状光Ｌ２となる。 As shown in FIG. 3, the light guide 110 includes an emission part 112 that emits light received from the light source 12 in the outer diameter direction of the rotation shaft 11 a. Specifically, the emission part 112 includes a first emission part 112a formed corresponding to the first range R1, and a second emission part 112b formed corresponding to the second range R2. . That is, the 1st output part 112a and the 2nd output part 112b are located so that the gauge intermediate position N may be adjoined in the circumference direction of the rotating shaft 11a. As shown in FIG. 5, the light emitted from the first emission part 112a becomes the first belt-like light L1. As shown in FIG. 6, the light emitted from the second emission part 112b becomes the second strip light L2.
　また、導光体１１０は、図５に示すように、第１出射部１１２ａに対応する第１受光部１１１ａを有する。ここで、複数の光源１２のうち、第１の範囲Ｒ１に対応して配設されたものを第１光源１２ａとすると、第１受光部１１１ａは、図５に示すように、第１光源１２ａと対向する。また、導光体１１０は、第１受光部１１１ａから内部に入射した第１光源１２ａからの光を回転軸１１ａの外径方向に向けて反射させる反射面を有する。第１の範囲Ｒ１に着目すると、導光体１１０は、第１光源１２ａが発した光を第１受光部１１１ａから受け、反射面を介して、第１出射部１１２ａから出射する。第１出射部１１２ａから出射された光が第１帯状光Ｌ１となる。 Further, as shown in FIG. 5, the light guide 110 has a first light receiving portion 111a corresponding to the first emitting portion 112a. Here, when the first light source 12a is a light source 12 disposed corresponding to the first range R1 among the plurality of light sources 12, the first light receiving unit 111a has the first light source 12a as shown in FIG. Opposite. In addition, the light guide 110 has a reflecting surface that reflects light from the first light source 12a incident on the inside from the first light receiving unit 111a toward the outer diameter direction of the rotation shaft 11a. Focusing on the first range R1, the light guide 110 receives the light emitted from the first light source 12a from the first light receiving unit 111a and emits the light from the first emitting unit 112a via the reflecting surface. The light emitted from the first emission part 112a becomes the first strip light L1.
　また、導光体１１０は、図６に示すように、第２出射部１１２ｂに対応する第２受光部１１１ｂを有する。ここで、複数の光源１２のうち、第２の範囲Ｒ２に対応して配設されたものを第２光源１２ｂとすると、第２受光部１１１ｂは、図６に示すように、第２光源１２ｂと対向する。また、導光体１１０は、第２受光部１１１ｂから内部に入射した第２光源１２ｂからの光を回転軸１１ａの外径方向に向けて反射させる反射面を有する。第２の範囲Ｒ２に着目すると、導光体１１０は、第２光源１２ｂが発した光を第２受光部１１１ｂから受け、反射面を介して、第２出射部１１２ｂから出射する。第２出射部１１２ｂから出射された光が第２帯状光Ｌ２となる。このようにして、導光体１１０は、第１帯状光Ｌ１に対応する第１の光路と、第２帯状光Ｌ２に対応する第２の光路とを実現する。 Moreover, the light guide 110 has the 2nd light-receiving part 111b corresponding to the 2nd output part 112b, as shown in FIG. Here, if the second light source 12b is a plurality of light sources 12 disposed corresponding to the second range R2, the second light receiving unit 111b has a second light source 12b as shown in FIG. Opposite. In addition, the light guide 110 has a reflection surface that reflects light from the second light source 12b incident on the inside from the second light receiving unit 111b toward the outer diameter direction of the rotation shaft 11a. Focusing on the second range R2, the light guide 110 receives the light emitted from the second light source 12b from the second light receiving unit 111b and emits the light from the second emitting unit 112b via the reflecting surface. The light emitted from the second emission part 112b becomes the second strip light L2. In this way, the light guide 110 realizes the first optical path corresponding to the first strip light L1 and the second optical path corresponding to the second strip light L2.
　また、第１出射部１１２ａと第２出射部１１２ｂとは、軸線ＡＸに沿う方向において異なる高さに位置し、ゲージ中間位置Ｎを境として段違いに形成されている。図５と図６を対比して分かるように、第１出射部１１２ａは、第２出射部１１２ｂよりも板部３０の近くに位置する。このように第１出射部１１２ａと第２出射部１１２ｂとが段違いに形成されていることにより、第１の光路を進み、第１帯状光Ｌ１として視認される光と、第２の光路を進み、第２帯状光Ｌ２として視認される光とは、互いに段違いの位置から出射される。 Further, the first emission part 112a and the second emission part 112b are located at different heights in the direction along the axis AX, and are formed stepwise with the gauge intermediate position N as a boundary. As can be seen by comparing FIG. 5 and FIG. 6, the first emission part 112 a is located closer to the plate part 30 than the second emission part 112 b. As described above, since the first emission part 112a and the second emission part 112b are formed in a step difference, the light travels along the first optical path, and travels along the light visually recognized as the first strip light L1 and the second optical path. The light that is visually recognized as the second band-like light L2 is emitted from a position different from each other.
　ガイドケース１２０は、後述する第１導光部１４１と第２導光部１４２を保持するものである。ガイドケース１２０は、例えば、ポリプロピレン等の樹脂から遮光性を有して形成されている。ガイドケース１２０は、その外周部において、公知の手法により回路基板１０に固定されている。また、ガイドケース１２０は、回転軸１１ａの近傍部で、導光体１１０を回路基板１０との間で挟持する。 The guide case 120 holds a first light guide 141 and a second light guide 142 which will be described later. The guide case 120 is formed, for example, from a resin such as polypropylene with a light shielding property. The guide case 120 is fixed to the circuit board 10 at the outer periphery thereof by a known method. The guide case 120 sandwiches the light guide 110 between the circuit board 10 and the vicinity of the rotating shaft 11a.
　ガイドケース１２０は、図３に示すように、軸線ＡＸを中心に扇状に形成された第１溝部１２１及び第２溝部１２２と、を有する。第１溝部１２１には、後述する第１導光部１４１が表側から嵌められる。第２溝部１２２には、後述する第２導光部１４２が裏側から嵌められる。また、ガイドケース１２０は、軸線ＡＸを中心とした円周方向において第１導光部１４１と第２導光部１４２とを隔てる遮光壁１２３を有している。第１溝部１２１は、第１の範囲Ｒ１に渡って設けられている。第２溝部１２２は、第２の範囲Ｒ２に渡って設けられている。遮光壁１２３は、ゲージ中間位置Ｎに沿って設けられている。 As shown in FIG. 3, the guide case 120 includes a first groove 121 and a second groove 122 formed in a fan shape around the axis AX. A first light guide 141 described later is fitted into the first groove 121 from the front side. A second light guide portion 142 to be described later is fitted into the second groove portion 122 from the back side. In addition, the guide case 120 includes a light shielding wall 123 that separates the first light guide portion 141 and the second light guide portion 142 in the circumferential direction about the axis AX. The first groove 121 is provided over the first range R1. The second groove 122 is provided over the second range R2. The light shielding wall 123 is provided along the gauge intermediate position N.
　第１溝部１２１は、軸線ＡＸを中心に放射状に延びるとともに、表側に向かって突出した複数の壁を有している。このような複数の壁を有していることにより、第１溝部１２１には、放射状に延びる複数の溝が形成されている。第１溝部１２１の軸線ＡＸ側は、導光体１１０の第１出射部１１２ａと対向している。第１溝部１２１の周縁は、インナーケース２０の仕切り部２１のうち第１の範囲Ｒ１に対応する部分と対向している。第１溝部１２１を構成する溝と、第１の範囲Ｒ１におけるインナーケース２０のセグメント２２とは、一対一で対応するように設けられている。 The first groove 121 has a plurality of walls extending radially about the axis AX and protruding toward the front side. By having such a plurality of walls, the first groove 121 has a plurality of radially extending grooves. The axis line AX side of the first groove 121 faces the first emitting part 112a of the light guide 110. The periphery of the first groove 121 faces the portion corresponding to the first range R1 in the partition portion 21 of the inner case 20. The grooves constituting the first groove 121 and the segments 22 of the inner case 20 in the first range R1 are provided so as to correspond one-to-one.
　第２溝部１２２は、軸線ＡＸを中心に放射状に延びるとともに、裏側に向かって突出した複数の壁を有している。このような複数の壁を有していることにより、第２溝部１２２には、放射状に延びる複数の溝が形成されている。第２溝部１２２の軸線ＡＸ側は、導光体１１０の第２出射部１１２ｂと対向している。第２溝部１２２の周縁は、インナーケース２０の仕切り部２１のうち第２の範囲Ｒ２に対応する部分と対向している。第２溝部１２２を構成する溝と、第２の範囲Ｒ２におけるインナーケース２０のセグメント２２とは、一対一で対応するように設けられている。 The second groove 122 has a plurality of walls extending radially about the axis AX and projecting toward the back side. By having such a plurality of walls, a plurality of radially extending grooves are formed in the second groove portion 122. The axis line AX side of the second groove part 122 faces the second emission part 112 b of the light guide 110. The peripheral edge of the second groove portion 122 faces the portion of the partition portion 21 of the inner case 20 corresponding to the second range R2. The grooves constituting the second groove portion 122 and the segments 22 of the inner case 20 in the second range R2 are provided so as to correspond one-to-one.
　また、ガイドケース１２０は、図５に示すように、第１溝部１２１の裏側に形成された第１空間１２４と、図６に示すように、第２溝部１２２の表側に形成された第２空間１２５とを有して形成されている。第１空間１２４は、第１の範囲Ｒ１において発光可能な第１帯状光Ｌ１の発光時に、第２の範囲Ｒ２が発光しないように、漏光をトラップする空間として設けられている。具体的には、第１空間１２４は、第１帯状光Ｌ１の発光時に、後述の遮光キャップ１３０の窓部１３２から第２の範囲Ｒ２に渡って漏れ出る光を抑制するために設けられている。第２空間１２５は、第２の範囲Ｒ２において発光可能な第２帯状光Ｌ２の発光時に、第１の範囲Ｒ１が発光しないように、漏光をトラップする空間として設けられている。具体的には、第２空間１２５は、第２帯状光Ｌ２の発光時に、後述の遮光キャップ１３０の窓部１３２から第１の範囲Ｒ１に渡って漏れ出る光を抑制するために設けられている。 The guide case 120 includes a first space 124 formed on the back side of the first groove 121 as shown in FIG. 5 and a second space formed on the front side of the second groove 122 as shown in FIG. 125. The first space 124 is provided as a space for trapping light leakage so that the second range R2 does not emit light when the first strip light L1 that can emit light in the first range R1 is emitted. Specifically, the first space 124 is provided to suppress light leaking from a window 132 of a light shielding cap 130 described later over the second range R2 when the first strip light L1 is emitted. . The second space 125 is provided as a space for trapping light leakage so that the first range R1 does not emit light when the second strip light L2 that can emit light in the second range R2 is emitted. Specifically, the second space 125 is provided in order to suppress light leaking over a first range R1 from a window portion 132 of a light shielding cap 130 described later when the second strip light L2 is emitted. .
　遮光キャップ１３０は、図５及び図６に示すように、指針２ａの指針キャップ２ｃと、板部３０の開口部３０ａとの間を塞ぐようにして設けられる。遮光キャップ１３０は、裏側に向かって開口する蓋状に形成されている。遮光キャップ１３０は、例えば、ポリカーボネート等からなる透明シートに黒印刷を実施し、圧空成形などで絞り加工を施すことで形成される。なお、遮光キャップ１３０は、射出成型の後に黒塗装を表面に施すことで形成してもよいし、遮光性を有する樹脂材によって形成してもよい。 As shown in FIGS. 5 and 6, the light shielding cap 130 is provided so as to block between the pointer cap 2 c of the pointer 2 a and the opening 30 a of the plate portion 30. The light shielding cap 130 is formed in a lid shape that opens toward the back side. The light shielding cap 130 is formed, for example, by performing black printing on a transparent sheet made of polycarbonate or the like, and drawing by pressure forming or the like. The light shielding cap 130 may be formed by applying black coating on the surface after injection molding, or may be formed of a resin material having light shielding properties.
　遮光キャップ１３０は、回転軸１１ａに対して固定され、指針２ａと共に軸線ＡＸを中心に回転する。例えば、遮光キャップ１３０は、指針２ａの指針キャップ２ｃに固定されていることで、指針２ａに固定されている。 The light shielding cap 130 is fixed with respect to the rotation shaft 11a and rotates around the axis AX together with the pointer 2a. For example, the light shielding cap 130 is fixed to the pointer 2a by being fixed to the pointer cap 2c of the pointer 2a.
　遮光キャップ１３０は、図３に示すように、回転軸１１ａの径方向において出射部１１２と対向して導光体１１０を覆う円筒状の壁部１３１を有する。壁部１３１には、透光性を有する窓部１３２が形成されている。例えば、窓部１３２は、遮光キャップ１３０において遮光性印刷層が無い部分により形成されている。なお、窓部１３２は、壁部１３１に設けられた開口部によって形成されてもよい。 As shown in FIG. 3, the light shielding cap 130 has a cylindrical wall portion 131 that covers the light guide 110 so as to face the emitting portion 112 in the radial direction of the rotation shaft 11 a. A window portion 132 having translucency is formed in the wall portion 131. For example, the window portion 132 is formed by a portion without the light-shielding print layer in the light-shielding cap 130. The window part 132 may be formed by an opening provided in the wall part 131.
　窓部１３２は、図３に示すように、遮光キャップ１３０の円周方向に沿って、互いに隣り合う第１窓部１３２ａ及び第２窓部１３２ｂを有する。第１窓部１３２ａと第２窓部１３２ｂとは、指針２ａの指示部２ｂを境として、隣り合うように配置されている。 As shown in FIG. 3, the window portion 132 includes a first window portion 132 a and a second window portion 132 b that are adjacent to each other along the circumferential direction of the light shielding cap 130. The 1st window part 132a and the 2nd window part 132b are arrange | positioned so that the instruction | indication part 2b of the pointer | guide 2a may be adjoined.
　また、第１窓部１３２ａと第２窓部１３２ｂとは軸線ＡＸに沿う軸方向において異なる高さに、段違いに位置している。図５と図６を対比して分かるように、第１窓部１３２ａは、第２窓部１３２ｂよりも板部３０の近くに位置する。第１窓部１３２ａは、導光体１１０の第１出射部１１２ａと同じ高さに位置する。第２窓部１３２ｂは、導光体１１０の第２出射部１１２ｂと同じ高さに位置する。 Further, the first window portion 132a and the second window portion 132b are positioned at different levels in the axial direction along the axis AX. As can be seen by comparing FIG. 5 and FIG. 6, the first window portion 132a is located closer to the plate portion 30 than the second window portion 132b. The first window part 132a is located at the same height as the first light emitting part 112a of the light guide 110. The second window part 132b is located at the same height as the second emission part 112b of the light guide 110.
　ここで、図４に示すように、指針２ａの指示部２ｂが丁度、ゲージ中間位置Ｎに位置しているときには、軸線ＡＸを中心とした径方向において、第１窓部１３２ａと第１出射部１１２ａとは重ならず、且つ、第２窓部１３２ｂと第２出射部１１２ｂとは重ならない。つまり、指示部２ｂがゲージ中間位置Ｎに位置しているときは、第１出射部１１２ａは、壁部１３１のうち第１窓部１３２ａと同じ高さにある部分と対向し、壁部１３１によって塞がれた状態となる。また、指示部２ｂがゲージ中間位置Ｎに位置しているときは、第２出射部１１２ｂは、壁部１３１のうち第２窓部１３２ｂと同じ高さにある部分と対向し、壁部１３１によって塞がれた状態となる。 Here, as shown in FIG. 4, when the indicating portion 2b of the pointer 2a is located at the gauge intermediate position N, the first window portion 132a and the first emitting portion are arranged in the radial direction around the axis AX. 112a does not overlap, and the second window portion 132b and the second emission portion 112b do not overlap. That is, when the indicating portion 2b is located at the gauge intermediate position N, the first emitting portion 112a faces a portion of the wall portion 131 that is at the same height as the first window portion 132a. It becomes a blocked state. When the indicator 2b is located at the gauge intermediate position N, the second emitting portion 112b is opposed to a portion of the wall 131 that is at the same height as the second window 132b. It becomes a blocked state.
　指針２ａの指示部２ｂがゲージ中間位置Ｎから反時計回りに回転すればするほど、第１窓部１３２ａのうち、第１出射部１１２ａと重なる領域が増加していく。つまり、指針２ａの指示部２ｂがゲージ中間位置Ｎから反時計回りに回転すればするほど、第１出射部１１２ａから出射され、第１窓部１３２ａを通過する光の量が増加していく。このような機構により、第１の範囲Ｒ１においては、後述するように第１帯状光Ｌ１が回転移動する指針２ａに追従して発光表示される。 As the indicating portion 2b of the pointer 2a rotates counterclockwise from the gauge intermediate position N, the region of the first window portion 132a that overlaps with the first emitting portion 112a increases. That is, the more the indicator 2b of the pointer 2a is rotated counterclockwise from the gauge intermediate position N, the more light is emitted from the first emission part 112a and passes through the first window part 132a. With such a mechanism, in the first range R1, as will be described later, the first belt-like light L1 is lit and displayed following the pointer 2a that rotates.
　指針２ａの指示部２ｂがゲージ中間位置Ｎから時計回りに回転すればするほど、第２窓部１３２ｂのうち、第２出射部１１２ｂと重なる領域が増加していく。つまり、指針２ａの指示部２ｂがゲージ中間位置Ｎから時計回りに回転すればするほど、第２出射部１１２ｂから出射され、第２窓部１３２ｂを通過する光の量が増加していく。このような機構により、第２の範囲Ｒ２においては、後述するように第２帯状光Ｌ２が回転移動する指針２ａに追従して発光表示される。 The more the indicator 2b of the pointer 2a is rotated clockwise from the gauge intermediate position N, the more the area of the second window 132b that overlaps with the second emitting part 112b increases. That is, the more the indicator 2b of the pointer 2a is rotated clockwise from the gauge intermediate position N, the more light is emitted from the second emission part 112b and passes through the second window part 132b. With such a mechanism, in the second range R2, as will be described later, the second band-like light L2 is lit and displayed following the pointer 2a that rotates.
　以上のように、第１窓部１３２ａは、指針２ａがゲージ中間位置Ｎから反時計回りに移動すればするほど、光を通過させる部分の面積が増加する。また、第２窓部１３２ｂは、指針２ａがゲージ中間位置Ｎから時計回りに移動すればするほど、光を通過させる部分の面積が増加する。 As described above, in the first window portion 132a, as the pointer 2a moves counterclockwise from the gauge intermediate position N, the area of the portion through which light passes increases. Further, as the pointer 2a moves clockwise from the gauge intermediate position N, the area of the second window portion 132b through which light passes is increased.
　導光部１４０は、ポリカーボネートなどの透明樹脂からなり、図３に示すように、第１導光部１４１と、第２導光部１４２と、を有する。 The light guide unit 140 is made of a transparent resin such as polycarbonate, and includes a first light guide unit 141 and a second light guide unit 142 as shown in FIG.
　第１導光部１４１は、図３に示すように、ガイドケース１２０の第１溝部１２１に表側から嵌められる。第１導光部１４１は、導光体１１０の第１出射部１１２ａから出射され、第１窓部１３２ａを通過した光を、インナーケース２０の仕切り部２１のうち第１の範囲Ｒ１に対応した部分に、効率良く導くために設けられる。第１導光部１４１は、軸線ＡＸを中心として放射状に延びるとともに、軸線ＡＸの円周方向に複数配列された櫛歯状に形成されている。第１導光部１４１を構成する複数の歯は、第１溝部１２１を構成する複数の溝に対応して形成されている。 As shown in FIG. 3, the first light guide 141 is fitted into the first groove 121 of the guide case 120 from the front side. The first light guide 141 corresponds to the first range R <b> 1 of the partition part 21 of the inner case 20, which is emitted from the first emission part 112 a of the light guide 110 and passes through the first window part 132 a. It is provided to guide the part efficiently. The first light guide portion 141 extends radially about the axis AX, and is formed in a comb-like shape that is arranged in a plurality in the circumferential direction of the axis AX. The plurality of teeth constituting the first light guide portion 141 are formed corresponding to the plurality of grooves constituting the first groove portion 121.
　なお、第１導光部１４１を構成する櫛歯は、一体に形成されてもよいが、複数の部材を組み合わせることで構成されてもよい。例えば、第１導光部１４１は、図７（ａ）、（ｂ）に示すように、第１の櫛歯状導光体１４１ａと、第２の櫛歯状導光体１４１ｂとを組み合わせることによって構成されてもよい。この場合、第１の櫛歯状導光体１４１ａを構成する複数の歯のうち、隣り合うもの同士の間に生じさせた間隔に、第２の櫛歯状導光体１４１ｂを構成する複数の歯が挿入可能なようにして、第１の櫛歯状導光体１４１ａと第２の櫛歯状導光体１４１ｂとを組み合わせればよい。このようにすることで、金型を用いた成形の制約を回避しつつ、細かな櫛歯形状を実現することができる。これは、第２導光部１４２についても同様である。 In addition, although the comb tooth which comprises the 1st light guide part 141 may be formed integrally, you may be comprised by combining a some member. For example, as shown in FIGS. 7A and 7B, the first light guide unit 141 combines the first comb-shaped light guide 141a and the second comb-shaped light guide 141b. It may be constituted by. In this case, among a plurality of teeth constituting the first comb-shaped light guide 141a, a plurality of teeth constituting the second comb-shaped light guide 141b are formed at intervals generated between adjacent ones. The first comb-shaped light guide 141a and the second comb-shaped light guide 141b may be combined so that teeth can be inserted. By doing in this way, a fine comb-tooth shape is realizable, avoiding the restrictions of shaping | molding using a metal mold | die. The same applies to the second light guide unit 142.
　第２導光部１４２は、図３に示すように、ガイドケース１２０の第２溝部１２２に裏側から嵌められる。第２導光部１４２は、導光体１１０の第２出射部１１２ｂから出射され、第２窓部１３２ｂを通過した光を、インナーケース２０の仕切り部２１のうち第２の範囲Ｒ２に対応した部分に、効率良く導くために設けられる。第２導光部１４２は、軸線ＡＸを中心として放射状に延びるとともに、軸線ＡＸの円周方向に複数配列された櫛歯状に形成されている。第２導光部１４２を構成する複数の歯は、第２溝部１２２を構成する複数の溝に対応して形成されている。 The 2nd light guide part 142 is engage | inserted from the back side to the 2nd groove part 122 of the guide case 120, as shown in FIG. The second light guide part 142 corresponds to the second range R2 of the partition part 21 of the inner case 20 with the light emitted from the second light emission part 112b of the light guide 110 and passed through the second window part 132b. It is provided to guide the part efficiently. The second light guide unit 142 extends radially about the axis AX, and is formed in a comb-teeth shape that is arranged in a plurality in the circumferential direction of the axis AX. The plurality of teeth constituting the second light guide part 142 are formed corresponding to the plurality of grooves constituting the second groove part 122.
　複合計器１の構成は以上である。続いて、指針式計器２の発光動作を説明する。 The configuration of the composite instrument 1 is as described above. Next, the light emission operation of the pointer-type meter 2 will be described.
　指針２ａの指示部２ｂが第１の範囲Ｒ１にあるときは、遮光キャップ１３０の第１窓部１３２ａは、導光体１１０の第１出射部１１２ａから出射される光を通す状態となる。このとき、当該光は、図５に示す第１の光路に沿って進行可能な状態となる。 When the indication part 2b of the pointer 2a is in the first range R1, the first window part 132a of the light shielding cap 130 is in a state of passing light emitted from the first emission part 112a of the light guide 110. At this time, the light can travel along the first optical path shown in FIG.
　図５に示すように、第１光源１２ａからの光は、導光体１１０の第１受光部１１１ａから内部に入射し、第１出射部１１２ａから軸線ＡＸを中心とした外径方向に出射される。第１出射部１１２ａから出射された光は、ガイドケース１２０の第１溝部１２１内にある第１導光部１４１に導かれて、インナーケース２０に形成されたセグメント２２の斜面２２ａで反射する。斜面２２ａで反射した光は、表側へと向かい、板部３０に形成された透過窓３１ｃを透過し、第１帯状光Ｌ１として視認される。 As shown in FIG. 5, the light from the first light source 12a is incident on the inside from the first light receiving portion 111a of the light guide 110, and is emitted from the first emitting portion 112a in the outer diameter direction centering on the axis AX. The The light emitted from the first emission part 112 a is guided to the first light guide part 141 in the first groove part 121 of the guide case 120 and reflected by the inclined surface 22 a of the segment 22 formed in the inner case 20. The light reflected by the inclined surface 22a goes to the front side, passes through the transmission window 31c formed in the plate portion 30, and is visually recognized as the first strip light L1.
　この際、指針２ａがゲージ中間位置Ｎよりも反時計回りに移動すればする程、第１窓部１３２ａを通過する光の量が増加し、第１窓部１３２ａからは、ゲージ中間位置Ｎから反時計回りに拡がる扇状の光が出射される。扇状の光が拡がれば拡がる程、櫛歯状の第１導光部１４１によって回転軸１１ａの外径方向へと導かれる光も、ゲージ中間位置Ｎから反時計回りに拡がっていく。そして、第１導光部１４１の櫛歯を構成する複数の歯先の各々からは、対応するセグメント２２に向けて光が出射される。結果として、ゲージ中間位置Ｎから指針２ａの指示部２ｂが指示している位置に渡って板部３０の透過窓３１ｃが発光し、ゲージ中間位置Ｎから反時計回りに、円弧状に延びる第１帯状光Ｌ１が視認される。透過窓３１ｃは、発光表示部３１ａにおいて円弧状に複数配列されているため、第１帯状光Ｌ１は、第１の範囲Ｒ１において円弧状に増減するバーグラフのように視認される。 At this time, as the pointer 2a moves counterclockwise from the gauge intermediate position N, the amount of light passing through the first window 132a increases, and from the gauge intermediate position N from the first window 132a. Fan-shaped light that spreads counterclockwise is emitted. As the fan-shaped light spreads, the light guided toward the outer diameter of the rotating shaft 11a by the comb-shaped first light guide 141 spreads counterclockwise from the gauge intermediate position N. Then, light is emitted toward the corresponding segment 22 from each of the plurality of tooth tips constituting the comb teeth of the first light guide unit 141. As a result, the transmission window 31c of the plate portion 30 emits light from the gauge intermediate position N to the position indicated by the indication portion 2b of the pointer 2a, and the first extension extending in an arc shape counterclockwise from the gauge intermediate position N. The strip light L1 is visually recognized. Since a plurality of transmission windows 31c are arranged in an arc shape in the light emitting display portion 31a, the first strip light L1 is visually recognized as a bar graph that increases or decreases in an arc shape in the first range R1.
　一方、指針２ａの指示部２ｂが第２の範囲Ｒ２にあるときは、遮光キャップ１３０の第２窓部１３２ｂは、導光体１１０の第２出射部１１２ｂから出射される光を通す状態となる。このとき、当該光は、図６に示す第２の光路に沿って進行可能な状態となる。 On the other hand, when the indication part 2b of the pointer 2a is in the second range R2, the second window part 132b of the light shielding cap 130 is in a state of passing light emitted from the second emission part 112b of the light guide 110. . At this time, the light can travel along the second optical path shown in FIG.
　図６に示すように、第２光源１２ｂからの光は、導光体１１０の第２受光部１１１ｂから内部に入射し、第２出射部１１２ｂから軸線ＡＸを中心とした外径方向に出射される。第２出射部１１２ｂから出射された光は、ガイドケース１２０の第２溝部１２２内にある第２導光部１４２に導かれて、インナーケース２０に形成されたセグメント２２の斜面２２ａで反射する。斜面２２ａで反射した光は、表側へと向かい、板部３０に形成された透過窓３１ｃを透過し、第２帯状光Ｌ２として視認される。 As shown in FIG. 6, the light from the second light source 12b is incident on the inside from the second light receiving portion 111b of the light guide 110, and is emitted from the second emitting portion 112b in the outer diameter direction centering on the axis AX. The The light emitted from the second emission part 112 b is guided to the second light guide part 142 in the second groove part 122 of the guide case 120 and reflected by the inclined surface 22 a of the segment 22 formed in the inner case 20. The light reflected by the inclined surface 22a goes to the front side, passes through the transmission window 31c formed in the plate part 30, and is visually recognized as the second band-like light L2.
　この際、指針２ａがゲージ中間位置Ｎよりも時計回りに移動すればする程、第２窓部１３２ｂを通過する光の量が増加し、第２窓部１３２ｂからは、ゲージ中間位置Ｎから時計回りに拡がる扇状の光が出射される。扇状の光が拡がれば拡がる程、櫛歯状の第２導光部１４２によって回転軸１１ａの外径方向へと導かれる光も、ゲージ中間位置Ｎから時計回りに拡がっていく。そして、第２導光部１４２の櫛歯を構成する複数の歯先の各々からは、対応するセグメント２２に向けて光が出射される。結果として、ゲージ中間位置Ｎから指針２ａの指示部２ｂが指示している位置に渡って板部３０の透過窓３１ｃが発光し、ゲージ中間位置Ｎから時計回りに、円弧状に延びる第２帯状光Ｌ２が視認される。透過窓３１ｃは、発光表示部３１ａにおいて円弧状に複数配列されているため、第２帯状光Ｌ２は、図１に示すように、第２の範囲Ｒ２において円弧状に増減するバーグラフのように視認される。 At this time, the more the pointer 2a moves in the clockwise direction from the gauge intermediate position N, the more light passes through the second window part 132b. Fan-shaped light spreading around is emitted. As the fan-shaped light spreads, the light guided toward the outer diameter direction of the rotation shaft 11a by the comb-shaped second light guide portion 142 also spreads clockwise from the gauge intermediate position N. Then, light is emitted from each of the plurality of tooth tips constituting the comb teeth of the second light guide unit 142 toward the corresponding segment 22. As a result, the transmission window 31c of the plate portion 30 emits light from the gauge intermediate position N to the position indicated by the indication portion 2b of the pointer 2a, and the second belt shape extending in an arc shape clockwise from the gauge intermediate position N. The light L2 is visually recognized. Since the plurality of transmission windows 31c are arranged in an arc shape in the light emitting display portion 31a, the second band light L2 is like a bar graph that increases or decreases in an arc shape in the second range R2, as shown in FIG. Visible.
　なお、第１帯状光Ｌ１と第２帯状光Ｌ２との発光色を変えたい場合には、（ｉ）複数の光源１２のうち、第１光源１２ａと第２光源１２ｂの発光色を変えてもよいし、（ｉｉ）遮光キャップ１３０の第１窓部１３２ａと第２窓部１３２ｂとに互いに色違いの透光性着色層を設けてもよいし、（ｉｉｉ）板部３０の発光表示部３１ａにおいて、第１の範囲Ｒ１にある透過窓３１ｃと、第２の範囲Ｒ２にある透過窓３１ｃとに、互いに色違いの透光性着色層を設けてもよいし、（ｉｖ）これらの組合せにより実現してもよい。 When it is desired to change the emission colors of the first strip light L1 and the second strip light L2, (i) among the plurality of light sources 12, the emission colors of the first light source 12a and the second light source 12b may be changed. (Ii) A translucent colored layer having a different color may be provided on the first window portion 132a and the second window portion 132b of the light shielding cap 130, or (iii) the light emitting display portion 31a of the plate portion 30. In the first range R1 and the transmission window 31c in the second range R2 may be provided with translucent colored layers of different colors, and (iv) It may be realized.
　また、指針２ａの回転に対する、バーグラフ状に視認される第１帯状光Ｌ１及び第２帯状光Ｌ２の点灯タイミングは、遮光キャップ１３０における、第１窓部１３２ａ及び第２窓部１３２ｂの各々の回転軸１１ａの円周方向に沿う長さを変化させることで、調整することが可能である。 In addition, the lighting timing of the first strip light L1 and the second strip light L2 that are visually recognized in the form of a bar graph with respect to the rotation of the pointer 2a is as follows. Adjustment is possible by changing the length of the rotating shaft 11a along the circumferential direction.
　また、以上では、板部３０へ向かう出射光を得るため、インナーケース２０の斜面２２ａを用いたが、第１導光部１４１及び第２導光部１４２の先端部を延長し、当該先端部の底面に反射面を設けることで、第１導光部１４１及び第２導光部１４２に導かれた光を板部３０に向かって反射させる構成を採用してもよい。この場合、インナーケース２０の仕切り部２１を省いても良い。 Further, in the above, the inclined surface 22a of the inner case 20 is used to obtain the emitted light directed to the plate part 30, but the distal ends of the first light guide part 141 and the second light guide part 142 are extended, and the distal part. A configuration may be adopted in which the light guided to the first light guide part 141 and the second light guide part 142 is reflected toward the plate part 30 by providing a reflective surface on the bottom surface of the first light guide part. In this case, the partition part 21 of the inner case 20 may be omitted.
　なお、本発明は以上の実施形態及び図面によって限定されるものではない。本発明の要旨を変更しない範囲で、適宜、変更（構成要素の削除も含む）を加えることが可能である。 In addition, this invention is not limited by the above embodiment and drawing. Changes (including deletion of components) can be made as appropriate without departing from the scope of the present invention.
（１）以上に説明した指針式計器２に含まれる発光装置は、回転軸１１ａの円周方向に延びる帯状光を視認させる。発光装置は、光源１２と、光源１２から受けた光を回転軸１１ａの外径方向に出射する出射部１１２を有する導光体１１０と、回転軸１１ａの径方向において出射部と対向する壁部１３１を有し、回転軸１１ａを中心に回転可能な遮光キャップ１３０（遮光部の一例）と、遮光キャップ１３０を回転させるモータ１１（駆動部の一例）と、を備える。壁部１３１は、出射部１１２から出射された光を通過させる窓部１３２を有する。この発光装置では、遮光キャップ１３０の回転に応じて、出射部１１２のうち窓部１３２から覗く部分の大きさが変化することによって、帯状光の発光範囲が変化する。
　このようにしたので、遮光キャップ１３０の回転に応じた斬新な発光表現を行うことができる。 (1) The light-emitting device included in the pointer-type meter 2 described above makes the band-like light extending in the circumferential direction of the rotating shaft 11a visible. The light-emitting device includes a light source 12, a light guide body 110 having an emission portion 112 that emits light received from the light source 12 in the outer diameter direction of the rotation shaft 11 a, and a wall portion that faces the emission portion in the radial direction of the rotation shaft 11 a. And a light shielding cap 130 (an example of a light shielding unit) that can rotate around a rotation shaft 11a, and a motor 11 (an example of a drive unit) that rotates the light shielding cap 130. The wall part 131 has a window part 132 through which the light emitted from the emission part 112 passes. In this light-emitting device, the light emission range of the band-like light is changed by changing the size of the portion of the emission unit 112 viewed from the window 132 in accordance with the rotation of the light shielding cap 130.
Since it did in this way, the novel light emission expression according to rotation of the light shielding cap 130 can be performed.
　なお、帯状光は、円弧状に視認されるものに限られず、扇状に視認されてもよい。また、発光装置は、指針式計器２に含まれていなくてもよい。また、出射部１１２は、互いに段違いに形成された第１出射部１１２ａ及び第２出射部１１２ｂを有していなくともよい。また、窓部１３２は、互いに段違いに形成された第１窓部１３２ａと第２窓部１３２ｂを有していなくともよい。 Note that the band-shaped light is not limited to the one that is visually recognized in an arc shape, and may be visually recognized in a fan shape. Further, the light emitting device may not be included in the pointer-type meter 2. In addition, the emission unit 112 may not include the first emission unit 112a and the second emission unit 112b that are formed in steps. Moreover, the window part 132 does not need to have the 1st window part 132a and the 2nd window part 132b which were formed in steps mutually.
（２）また、出射部１１２は、第１出射部１１２ａと、第１出射部１１２ａと回転軸１１ａに沿う方向（軸線ＡＸに沿う方向）において異なる高さに位置する第２出射部１１２ｂと、を有する。窓部１３２は、第１出射部１１２ａから出射された光を通過させる第１窓部１３２ａと、第２出射部１１２ｂから出射された光を通過させる第２窓部１３２ｂと、を有する。帯状光は、第１窓部１３２ａを通過した光に対応して視認される第１帯状光Ｌ１と、第２窓部１３２ｂを通過した光に対応して視認される第２帯状光Ｌ２と、を含む。遮光キャップ１３０の回転に応じて、第１出射部１１２ａのうち第１窓部１３２ａから覗く部分の大きさが変化することによって第１帯状光Ｌ１の発光範囲が変化し、第２出射部１１２ｂのうち第２窓部１３２ｂから覗く部分の大きさが変化することによって第２帯状光Ｌ２の発光範囲が変化する。
　このように遮光キャップ１３０の回転に応じて、第１帯状光Ｌ１と第２帯状光Ｌ２の発光範囲を変化させることができるため、斬新な発光表現を行うことができる。 (2) The emission unit 112 includes a first emission unit 112a, a second emission unit 112b located at different heights in a direction along the first emission unit 112a and the rotation shaft 11a (a direction along the axis AX), and Have The window part 132 includes a first window part 132a that allows light emitted from the first emission part 112a to pass therethrough, and a second window part 132b that allows light emitted from the second emission part 112b to pass therethrough. The band-shaped light is a first band-shaped light L1 that is visually recognized corresponding to the light that has passed through the first window 132a, a second band-shaped light L2 that is visually recognized corresponding to the light that has passed through the second window 132b, including. In accordance with the rotation of the light shielding cap 130, the emission range of the first strip light L1 is changed by changing the size of the portion of the first emission part 112a that is viewed through the first window part 132a. Among these, the emission range of the second strip light L2 changes as the size of the portion viewed from the second window 132b changes.
Thus, since the light emission range of the first belt-like light L1 and the second belt-like light L2 can be changed according to the rotation of the light shielding cap 130, a novel light emission expression can be performed.
（３）また、遮光キャップ１３０における第１窓部１３２ａと第２窓部１３２ｂとは互いに、回転軸１１ａの円周方向において重ならない位置に設けられ、遮光キャップ１３０が第１の方向（例えば、反時計回り）に回転するに従って、第１出射部１１２ａのうち第１窓部１３２ａから覗く部分が大きくなることによって、第１帯状光Ｌ１の発光範囲が増加し、遮光キャップ１３０が第１の方向とは反対の第２の方向（例えば、時計回り）に回転するに従って、第２出射部１１２ｂのうち第２窓部１３２ｂから覗く部分が大きくなることによって、第２帯状光Ｌ２の発光範囲が増加する、ようにしてもよい。 (3) Further, the first window portion 132a and the second window portion 132b of the light shielding cap 130 are provided at positions that do not overlap with each other in the circumferential direction of the rotation shaft 11a, and the light shielding cap 130 has a first direction (for example, As the portion of the first emitting portion 112a that is viewed from the first window portion 132a increases as it rotates counterclockwise), the light emission range of the first strip light L1 increases, and the light shielding cap 130 moves in the first direction. As the portion rotates in the second direction opposite to (for example, clockwise), the portion of the second emitting portion 112b that is viewed through the second window portion 132b increases, thereby increasing the emission range of the second strip light L2. You may do it.
