Specifically, the index unit 71 indicates numerical values of −100 kPa, −80 kPa, −60 kPa, −40 kPa, −20 kPa, 0 kPa, +50 kPa, +100 kPa, +150 kPa, and +200 kPa, and ten main graduations corresponding to predetermined numerical values. And a sub-scale provided between the main scale. The user can read the vehicle information by comparing and reading the pointer 21 and the indicator 71 printed on the display plate 7.
　拡散板８は、表示板７と第二の光源６との間に配設され、表示板７に向けて出射される第二の照明光Ｌ２を表示板７の全面に向けて拡散させる円板状の拡散部材である。拡散板８は、中央部分に回転軸２２ａが貫通し、第一の照明光Ｌ１を通過させる孔部８ａを有する。 The diffusing plate 8 is disposed between the display panel 7 and the second light source 6 and diffuses the second illumination light L2 emitted toward the display panel 7 toward the entire surface of the display panel 7. Is a diffusion member. The diffusion plate 8 has a hole 8a through which a rotation shaft 22a penetrates and passes the first illumination light L1 at a central portion.
　見返し部材９は、アクリル、ポリカーボネート等の透過性の樹脂材料からなり、着色剤により環状透光部７２と同系色又は類似色の濃色、例えば紺色に着色されて形成される。見返し部材９は、メータケース３と前面カバー４との間に表示部２を囲むように配設されるリング状の部材であり、前面カバー４の段差部４１と対向する位置に配置される。見返し部材９は、環状透光部７２の少なくとも一部を覆っており、環状透光部７２が覆われる幅Ｗ２は環状透光部７２が覆われない幅Ｗ１よりも広い。見返し部材９は、環状透光部７２を透過した第二の照明光Ｌ２により、紺色に透過照明される。このとき、前面カバー４の段差部４１と対向する見返し部材９から第二の照明光Ｌ２が外部に出射されるため、ユーザは、前面カバー４の外周がリング状に発光しているような印象を受ける。 The return member 9 is made of a transparent resin material such as acryl or polycarbonate, and is formed by being colored with a colorant in a similar color or a similar color to the annular translucent portion 72, such as a dark blue color. The dial member 9 is a ring-shaped member disposed between the meter case 3 and the front cover 4 so as to surround the display unit 2, and is arranged at a position facing the step 41 of the front cover 4. The look-back member 9 covers at least a part of the annular translucent portion 72, and a width W2 covering the annular translucent portion 72 is wider than a width W1 not covering the annular translucent portion 72. The viewing member 9 is illuminated in dark blue by the second illumination light L2 transmitted through the annular light transmitting portion 72. At this time, since the second illumination light L2 is emitted to the outside from the facing member 9 facing the step portion 41 of the front cover 4, the user feels that the outer periphery of the front cover 4 is emitting in a ring shape. Receive.
　以上の各部によって車両用計器１が構成されている。 The instrument 1 for a vehicle is constituted by the above components.
　本態様の車両用計器１において、第二の照明光Ｌ２は、直接、及び／又は中ケース３２で反射されることで拡散板８に入射し、第二の照明光Ｌ２の一部が環状透光部７２から出射される。環状透光部７２から出射された第二の照明光Ｌ２について、見返し部材９に覆われていない部分（幅Ｗ１）は環状透光部７２を透過照明し、見返し部材９に覆われた部分（幅Ｗ２）は環状透光部７２及び見返し部材９を透過照明する。このとき、ユーザが正面から車両用計器１を視認すると、表示板７の外周に水色のリング状の発光と、その外側且つ前面カバー４の外周に紺色のリング状の発光と、を有する意匠と観察することができ、車両用計器１の視認性及びデザイン性を向上させることができる。
　また、ユーザは、環状透光部７２の発光よりも前面カバー４の外周（見返し部材９）の発光に近い位置の印象を受けるため、車両用計器１の立体感をより高めることができる。 In the vehicle instrument 1 of this embodiment, the second illumination light L2 is incident on the diffusion plate 8 directly and / or by being reflected by the middle case 32, and a part of the second illumination light L2 is annularly transparent. The light is emitted from the light unit 72. With respect to the second illumination light L2 emitted from the annular light transmitting portion 72, a portion (width W1) not covered by the look-back member 9 transmits and illuminates the annular light-transmitting portion 72, and a portion covered by the look-apart member 9 ( The width W2) illuminates the annular translucent portion 72 and the return member 9 with transmitted light. At this time, when the user visually recognizes the vehicle instrument 1 from the front, a design having light blue ring-shaped light emission on the outer periphery of the display panel 7 and dark blue ring-shaped light emission on the outside thereof and on the outer periphery of the front cover 4 is obtained. It can be observed, and the visibility and design of the vehicle instrument 1 can be improved.
In addition, since the user receives an impression of a position closer to the light emission of the outer periphery (return member 9) of the front cover 4 than the light emission of the annular translucent portion 72, the three-dimensional effect of the vehicle instrument 1 can be further enhanced.
　また、ユーザが斜めから車両用計器１を視認すると、見返し部材９の環状透光部７２に近い側（第二の光源６に近い側）が明るく透過照明され、見返し部材９の前面カバー４に近い側（第二の光源６に遠い側）が暗く透過照明されるように観察できる。これにより、ユーザは、見返し部材９の高さを強調して感じることができ、車両用計器１の立体感をより高めることができる。 Further, when the user visually recognizes the vehicle instrument 1 from an oblique direction, the side near the annular translucent portion 72 (the side near the second light source 6) of the return member 9 is brightly transmitted and illuminated. Observation can be made such that the near side (the side far from the second light source 6) is darkly transmitted through. Thereby, the user can emphasize and feel the height of the return member 9, and can further enhance the three-dimensional appearance of the vehicle instrument 1.
　また、車両用計器１は、第一の光源５、及び／又は第二の光源６の点灯／消灯により指針２１、表示板７、見返し９の見栄えが変化する。これにより、車両のキースイッチのオン状態（車両走行時）とオフ状態（車両停車時）とでユーザに異なる印象を与え、車両用計器１のデザイン性を向上させることができる。 {Circle around (1)} In the vehicle instrument 1, the appearance of the hands 21, the display panel 7, and the facing 9 is changed by turning on / off the first light source 5 and / or the second light source 6. This gives a different impression to the user depending on whether the key switch of the vehicle is on (when the vehicle is running) or off (when the vehicle is stopped), and the design of the vehicle instrument 1 can be improved.
　また、車両用計器１は、見返し部材９の色を環状透光部７２よりも濃色とすることにより、ユーザがメータケース３内の構造（例えば、中ケース３２が表示板７及び拡散板８を支持している部位）を視認しづらくすることができる。 Further, in the vehicle instrument 1, the color of the facing member 9 is made darker than that of the annular translucent portion 72, so that the user can use the structure inside the meter case 3 (for example, the middle case 32 is connected to the display plate 7 and the diffusion plate 8). Can be hardly visually recognized.
　なお、本態様において、見返し部材９の色は、環状透光部７２の色から色相を４５度ずらした色までを類似色としてもよい。具体的には、マンセルの色相環において、環状透光部７２の色をオレンジ色（10YR）とし、見返し部材９の色を赤色（5R）としても同様の効果を得ることができる。 In the present embodiment, the color of the dial member 9 may be similar to the color of the annular translucent portion 72 up to a color whose hue is shifted by 45 degrees. Specifically, in the Munsell hue circle, the same effect can be obtained by setting the color of the annular translucent section 72 to orange (10YR) and the color of the return member 9 to red (5R).
　また、本発明を車両に予め備えられたアナログメータ（純正メータ）に適用してもよく、複数のアナログ式表示部とデジタル式表示部とを備えるコンビネーションメータに適用してもよい。 The present invention may be applied to an analog meter (genuine meter) provided in a vehicle in advance, or may be applied to a combination meter including a plurality of analog display units and digital display units.
　本発明は、車両情報を表示する計器装置に関し、特に単一のアナログ式表示部をケース体内に収納してなるいわゆる単眼式のアフターメータに好適である。 The present invention relates to an instrument device for displaying vehicle information, and is particularly suitable for a so-called monocular aftermeter in which a single analog display portion is housed in a case body.
