A display panel 12 housed in the space, a display panel light guide 13 housed in the space, and a light emitting diode that illuminates the display panel 12 from the back through the display panel light guide 13. The display unit 14 is formed by a light source (fourth light source) L4 composed of Although not shown in the present example, the display unit 14 incorporates a diffusion sheet for uniforming the light of the light source L4, a reflection sheet for improving light reflectivity, a toning sheet for suppressing color unevenness, and a display panel. A polarizing sheet is attached to 12.

第１のケース部材（第１の隠蔽部）８ａの外縁部のうち、指針７の運動経路（作動範囲）に対応する領域は、指針７の運動経路に沿った円弧状に形成され、さらに中央領域には、外縁部と同様の円弧状部と直線部とを有し直線部が底辺となるような「Ｄ」字形状に開口する窓部８ｃが形成され、この窓部８ｃに表示パネル１２の後述する表示領域が臨む構成である。   Of the outer edge portion of the first case member (first concealing portion) 8a, the region corresponding to the movement path (operation range) of the pointer 7 is formed in an arc shape along the movement path of the pointer 7, and further in the center. In the region, there is formed a window portion 8c having an arcuate portion and a straight line portion similar to the outer edge portion and opening in a “D” shape such that the straight line portion is the bottom, and the display panel 12 is formed in the window portion 8c. The display area which will be described later faces.

表示パネル１２は、様々な情報を表示する例えば液晶パネルからなる電子式表示パネルであって、本実施形態では平面形状が窓部８ｃに相似し、窓部８ｃより大きく第１の隠蔽部８ａより小さな「Ｄ」字形に形成され、情報内容を示す表示部（画素（ドット）部またはセグメント部で構成）１２１とこの表示部の背景をなす背景部（画素（ドット）部またはセグメント部で構成）１２２とで様々な情報を表示する表示領域ＤＲを有している。この表示領域ＤＲは、表示パネル１２の外形形状に相似し、窓部８ｃより若干大きな「Ｄ」字形に設定され、例えばこの例では、表示情報として車両の走行距離である数値情報と、簡易ナビゲーション情報である図形情報とを表示するもので、この表示領域が窓部８ｃより露出している。   The display panel 12 is an electronic display panel composed of, for example, a liquid crystal panel for displaying various information. In the present embodiment, the planar shape is similar to the window portion 8c, and is larger than the window portion 8c and from the first concealing portion 8a. A display portion (comprising a pixel (dot) portion or a segment portion) 121 that is formed in a small “D” shape and indicates information content, and a background portion (consisting of a pixel (dot) portion or a segment portion) that forms the background of this display portion 122 has a display area DR for displaying various information. The display area DR is similar to the outer shape of the display panel 12 and is set to a “D” shape slightly larger than the window portion 8c. In this example, for example, numerical information that is the travel distance of the vehicle and simple navigation are displayed information. The graphic information which is information is displayed, and this display area is exposed from the window portion 8c.

表示パネル用導光体１３は、透光性の良好な合成樹脂材料からなり、表示パネル１２の背後に配置され、点光源である光源Ｌ４の光を面発光に変換して表示パネル１２に導く機能を有している。   The display panel light guide 13 is made of a synthetic resin material having good translucency, and is disposed behind the display panel 12. The light of the light source L 4, which is a point light source, is converted into surface light and led to the display panel 12. It has a function.

次に光源Ｌ１〜Ｌ４が点灯する照明状態を説明するが、本実施形態では例えば図示しない始動スイッチ、またはライトスイッチ、またはドアスイッチに連動して各光源Ｌ１〜Ｌ４が一斉に点灯するものとするが、点灯順は任意に設定できる。   Next, an illumination state in which the light sources L1 to L4 are turned on will be described. In this embodiment, for example, the light sources L1 to L4 are turned on all at once in conjunction with a start switch, a light switch, or a door switch (not shown). However, the lighting order can be set arbitrarily.

まず第１の光源Ｌ１が点灯すると、その光（この場合白色）の一部は表示板用導光体９に入射した後、側端面に設けられた出射部から放射状に出射し、その出射光は、枠体５の傾斜面と表示板６の裏面との間を繰り返し反射し、その反射光が指標部６２を透過することによって、指標部６２を明るく照らし出す。なお地部６１は遮光性を有するため、光は透過しない。従って、第１の光源Ｌ１のみが点灯した場合は、地部６１による黒色の背景中に白色に光輝する指標部６２が視認される。   First, when the first light source L1 is turned on, a part of the light (in this case, white) is incident on the light guide 9 for the display plate, and then is emitted radially from the emitting portion provided on the side end surface. Is repeatedly reflected between the inclined surface of the frame 5 and the back surface of the display panel 6, and the reflected light passes through the indicator portion 62 to illuminate the indicator portion 62 brightly. Since the ground portion 61 has a light shielding property, it does not transmit light. Therefore, when only the first light source L1 is lit, the indicator portion 62 that shines white in the black background by the ground portion 61 is visually recognized.

次に第２の光源Ｌ２が点灯すると、その光の多くは指針用導光体１０を通じて導光反射部７１に至って反射され、指針７の指示部７ｂを前記反射層と同じ赤色に光輝させる。なおこの場合、第２の光源Ｌ２の発光色は、指示部７ｂを赤色に光輝させることができれば、白色でも赤色でもよい。   Next, when the second light source L2 is turned on, most of the light is reflected through the pointer light guide 10 to the light guide reflection portion 71, and the indicator portion 7b of the pointer 7 shines in the same red color as the reflection layer. In this case, the light emission color of the second light source L2 may be white or red as long as the indicator 7b can be illuminated in red.

次に第３の光源Ｌ３が点灯すると、その光（この場合青色）の多くは円錐形の反射壁部７２に貼着された反射部材７３で放射状に反射され、このように反射された光は、表示板６の地部６１表面に至り、シルバー色となる地部６１の特定領域を青色に照らす発光模様（装飾意匠）Ｍを形成する。この発光模様Ｍは、図１中、点線で示すように、全体が表示ユニット１４の外周を指針７の動作範囲に沿って取り巻く円弧状を呈し、第３の光源Ｌ３からの距離に応じて濃い青色（光源Ｌ３に近い側）から淡い青色（光源Ｌ３に遠い側）に徐々に変化するグラデーション模様として視認される。   Next, when the third light source L3 is turned on, most of the light (in this case, blue) is reflected radially by the reflecting member 73 attached to the conical reflecting wall 72, and the reflected light is Then, a light emitting pattern (decorative design) M is formed which reaches the surface of the ground portion 61 of the display board 6 and illuminates a specific area of the ground portion 61 that is silver in blue. As shown by a dotted line in FIG. 1, the light emission pattern M has an arc shape that surrounds the outer periphery of the display unit 14 along the operating range of the pointer 7, and is dark according to the distance from the third light source L3. It is visually recognized as a gradation pattern that gradually changes from blue (side closer to the light source L3) to light blue (side far from the light source L3).

次に第４の光源Ｌ４が点灯すると、その光（この場合青色）の多くは表示パネル用導光体１３に入射して面発光に変換され、表示パネル１２に導かれ、表示パネル１２の表示領域ＤＲを照明する。この際、表示領域ＤＲにおいて、情報内容を示す表示部１２１は、画素（ドット）部または表示セグメント部を遮光状態に切り換える（液晶分子を通して遮光状態となるように制御する）ことにより数値情報や図形情報等の表示情報を形成し、これとは反対に背景部１２２は、画素（ドット）部または表示セグメント部を透光状態に切り換える（液晶分子を通して透光状態となるように制御する）ことにより形成され、この結果、青色の発光領域となる背景部１２２内に黒色の表示部１２１でなる表示情報が表示される。なお表示部１２１も背景部１２２と同様の光透過領域（発光領域）で形成してもよいが、背景部１２２との差別化をはかるため、発光色を変更する等の対応が必要である。   Next, when the fourth light source L4 is turned on, most of the light (in this case, blue) enters the display panel light guide 13 and is converted into surface light emission, which is guided to the display panel 12 and displayed on the display panel 12. The area DR is illuminated. At this time, in the display region DR, the display unit 121 indicating the information content switches the pixel (dot) unit or the display segment unit to a light-shielding state (controls the light-shielding state through the liquid crystal molecules) to display numerical information and graphics. On the other hand, the background portion 122 switches the pixel (dot) portion or the display segment portion to a light-transmitting state (controls the light-transmitting state through liquid crystal molecules). As a result, display information including the black display portion 121 is displayed in the background portion 122 serving as a blue light emitting region. The display unit 121 may also be formed with a light transmission region (light emitting region) similar to the background unit 122, but in order to differentiate from the background unit 122, it is necessary to take measures such as changing the emission color.

またこの場合、窓部８ｃを通じて視認される青色の背景部１２２の輪郭Ｃは、窓部８ｃの開口形状に合致した「Ｄ」字形となり、輪郭Ｃのうち、直線部を除く部位、すなわち、指針７の動作範囲に対応する部分は、第１の遮蔽部８ａの外縁部及び窓部８ｃと同様に、指針７の動作範囲（回転軌道）に対応する円弧形状となるものである。   In this case, the contour C of the blue background portion 122 visually recognized through the window portion 8c is a “D” shape that matches the opening shape of the window portion 8c. The portion corresponding to the movement range 7 has an arc shape corresponding to the movement range (rotation trajectory) of the pointer 7 like the outer edge portion of the first shielding portion 8a and the window portion 8c.

最後に発光色の観点から発光形態をまとめると以下の通りとなる。
指標部６２→白色で発光
指針７→赤色で発光
発光模様Ｍ→濃い青色から淡い青色に変化するグラデーションで発光
背景部１２２→発光模様Ｍのうち濃い青色と同じかこれに近い濃い青色で発光 Finally, the light emission forms are summarized as follows from the viewpoint of the emission color.
Indicator part 62 → Light emission pointer 7 in white → Light emission pattern M in red → Light emission background part 122 → Light emission in dark blue that is the same as or close to dark blue in light emission pattern M with gradation changing from dark blue to light blue

以上の通り、本実施形態では、指針７と、この指針７を回転動作させる駆動装置４と、この指針７が指示する指標部６２を有する表示板６と、指針７の回転軌道内に配置される表示ユニット１４とを備えており、表示ユニット１４が所定情報を表示するための表示領域ＤＲを有する表示パネル１２と、表示領域ＤＲを視認可能とする窓部８ｃを有する第１の隠蔽部（ケース部材）８ａとからなり、表示領域ＤＲが所定情報の背景を形成する背景部１２２を有し、この背景部１２２を発光領域に設定すると共に窓部８ｃを通じて視認される背景部１２２の輪郭Ｃのうち少なくとも指針７の動作範囲に対応する部分を円弧状に設定したことにより、照明時において、表示パネル１２の発光意匠を、指針７の動作範囲を基準とする指針式表示部の発光意匠に合致もしくは対応させることができ、これにより両発光意匠を調和させ、発光意匠に統一感を付与することができ、見栄え品質を向上させることができる。   As described above, in the present embodiment, the pointer 7, the driving device 4 that rotates the pointer 7, the display board 6 that has the indicator portion 62 that is indicated by the pointer 7, and the rotation path of the pointer 7 are arranged.

The background portion 122 is set as a light emitting region, and the contour C of the background portion 122 visually recognized through the window portion 8c. By setting at least the portion corresponding to the operating range of the pointer 7 in an arc shape, the light emitting design of the display panel 12 can be displayed on the indicator-type display unit based on the operating range of the pointer 7 during illumination.

In addition to the improvement of the effect, the presence of the first concealing portion 8a serving as the edge can be made inconspicuous.

また本実施形態では、背景部１２２の発光色と発光模様（装飾意匠）Ｍの発光色とが濃い青色となるように同調させたことにより、形状だけでなく色調にも統一感を付与することができる。なおここで同調とは、実質的に同じ色はもちろんだか、同色に限らず、例えば淡い青色、濃い青色等の色の濃淡、緑色または黄色または水色がかった青色等の系列色を網羅するものであればよく、設定色も青色に限らず任意である。   Further, in the present embodiment, by synchronizing the light emission color of the background portion 122 and the light emission color of the light emission pattern (decorative design) M so as to be dark blue, not only the shape but also the color tone is given a sense of unity.

In this example, the outer shape of the display panel 12 is set to a polygon (in this case, a hexagon) as shown by a dotted line in the figure, and a window The outline C of the background part 122 visually recognized from the part 8c is set in the same manner as in the first embodiment, and the same operational effects as in the first embodiment can be obtained also in this embodiment. If it is a polygon (especially when the number of corners is small), the width of the first concealing portion 8a serving as an edge is larger than that of the arc-shaped first embodiment, or the area of the display region DR May become smaller. Note that the outer shape of the display panel 12 is arbitrary as long as the shape of the background portion 122 corresponds to the rotation orbit of the pointer 7, and may be, for example, a quadrangular shape.

なお本発明の第３の実施形態として、図示しないが、表示パネル１２は、発光によって情報を表示するものであって、背景部が発光領域であってその輪郭の少なくとも一部が指針の回転軌道に対応する形状であれば、任意のものを用いることができ、電子式以外の表示パネル、例えば表示板７と同様、光透過により情報表示を行う透過パネルを用いてもよい。さらに電子式の表示パネルを用いる場合、液晶パネルに限らず、例えば電界発光素子や蛍光表示管、発光ダイオード表示器を用いてもよく、これら電子式の表示パネルと前記透過パネルを組み合わせたもので表示領域を形成するものでもよい。   As a third embodiment of the present invention, although not shown, the display panel 12 displays information by light emission, the background portion is a light emission region, and at least a part of its outline is a rotation trajectory of the pointer. Any shape can be used as long as the shape corresponds to the above, and a display panel other than an electronic type, for example, a display panel that displays information by light transmission may be used similarly to the display plate 7. Further, when an electronic display panel is used, not only a liquid crystal panel but also, for example, an electroluminescent element, a fluorescent display tube, or a light emitting diode display may be used, which is a combination of the electronic display panel and the transmission panel. A display area may be formed.
