図1、図2において、本実施形態による表示装置としての速度計は、回路基板10と、この回路基板10に導通装着され回転軸20が前方に延びる駆動装置30と、回転軸20にて回転駆動される指針40と、この指針40の背後に位置して回路基板10上に配置される表示パネル50と、その主要部が回路基板10と表示パネル50との間に位置している導光部材60と、指針40に照明光を供給する指針用光源70と、導光部材60に照明光を供給する光源80と、主に導光部材60を保持する機能を有するケース体90と、表示パネル50の前方側に位置している導光部100と、この導光部100を覆うように表示パネル50上に配置される装飾リング110とを備えている。   1 and 2, the speedometer as a display device according to the present embodiment includes a circuit board 10, a driving device 30 that is conductively attached to the circuit board 10 and has a rotating shaft 20 extending forward, and is rotated by the rotating shaft 20. A pointer 40 to be driven, a display panel 50 disposed on the circuit board 10 behind the pointer 40, and a light guide whose main part is located between the circuit board 10 and the display panel 50. A member 60, a pointer light source 70 for supplying illumination light to the pointer 40, a light source 80 for supplying illumination light to the light guide member 60, a case body 90 mainly having a function of holding the light guide member 60, and a display The light guide part 100 located in the front side of the panel 50 is provided, and the decoration ring 110 arrange | positioned on the display panel 50 so that this light guide part 100 may be covered.

回路基板10は、例えばガラスエポキシ系基材に配線パターン(図示せず)を施した硬質回路基板からなり、指針用光源70と、光源80と、例えば駆動装置30の駆動・制御を行う駆動手段(図示せず)と、抵抗、コンデンサ等の各種回路部品(図示せず)とが前記配線パターンに導通接続されている。   The circuit board 10 is made of a hard circuit board in which, for example, a glass epoxy base material is provided with a wiring pattern (not shown), and driving means for driving and controlling the pointer light source 70, the light source 80, and the driving device 30, for example. (Not shown) and various circuit components (not shown) such as resistors and capacitors are conductively connected to the wiring pattern.

駆動装置30は、可動磁石式計器またはステッピングモータからなり、回転軸20が回路基板10を貫通するように、その主要部が回路基板10の背後に装着され、且つ半田付け等の適宜導通手段により前記配線パターン(前記駆動手段)に電気接続される。   The driving device 30 is composed of a movable magnet type instrument or a stepping motor, and its main part is mounted behind the circuit board 10 so that the rotating shaft 20 penetrates the circuit board 10 and is appropriately connected by means such as soldering. It is electrically connected to the wiring pattern (the driving means).

指針40は、透光性の合成樹脂からなり、回転軸20の先端に連結され、その回転中心部には遮光性カバーが装着されている。そして、この指針40は指針用光源70からの照明光を受けて発光する発光式指針である。   The pointer 40 is made of a light-transmitting synthetic resin, is connected to the tip of the rotating shaft 20, and a light-shielding cover is attached to the center of rotation. The pointer 40 is a light-emitting pointer that emits light upon receiving illumination light from the pointer light source 70.

表示パネル50は、指針40の作動範囲に沿った円弧状の配列形状を有し、指針40によって指示される複数個の速度数字からなる計測値表示部51と、この計測値表示部51の背景を形成する遮光層からなる背景部52と、後述する貫通部の外側で背景部52を計測値表示部51(前記貫通部)を包囲するように略円環状(または略馬蹄形状)に抜き形成してなる光透過部53とが設けられている(図3参照)。   The display panel 50 has an arcuate array shape along the operating range of the pointer 40, a measurement value display unit 51 composed of a plurality of speed numbers indicated by the pointer 40, and a background of the measurement value display unit 51 And a background portion 52 made of a light shielding layer and a background portion 52 outside the penetrating portion to be described later and formed in a substantially annular shape (or substantially horseshoe shape) so as to surround the measured value display portion 51 (the penetrating portion). The light transmission part 53 which consists of this is provided (refer FIG. 3).

これら計測値表示部51、背景部52並びに光透過部53は、計測値表示部51が例えば白色の透光性インクにより、背景部52が例えば黒色の遮光性インクにより、それぞれ表示パネル50の母材となる薄板状からなる光透過性の基板54の表面に印刷形成される。   The measurement value display unit 51, the background unit 52, and the light transmission unit 53 are configured such that the measurement value display unit 51 is made of, for example, white translucent ink, and the background unit 52 is made of, for example, black light-shielding ink. It is printed on the surface of a light-transmitting substrate 54 made of a thin plate as a material.

光透過部53は、背景部52を形成する遮光性インクを抜き印刷することにより、背景部52が形成されない抜き印刷部分からなり、従って、光透過部53の形成個所においては、基板54が部分的に露出し、導光部材60を通じて導かれた光源80からの照明光を導光部100側に透過できるようになっている。   The light transmitting portion 53 is formed by a non-printed portion where the background portion 52 is not formed by removing and printing the light-shielding ink that forms the background portion 52, and therefore, the substrate 54 is a part of the portion where the light transmitting portion 53 is formed. Thus, the illumination light from the light source 80 guided through the light guide member 60 can be transmitted to the light guide unit 100 side.

また、光透過部53の前面には、例えば青色の透光性インクにより着色層(着色手段)55が印刷形成されている。この着色層55は、光源80の発光色(ここでは白色光)とは異なる色調である青色を有するものであり、光透過部53と導光部100との間に挟まれるように表示パネル50の周縁に位置している。   Further, a colored layer (coloring means) 55 is printed and formed on the front surface of the light transmitting portion 53 using, for example, blue light transmitting ink. The colored layer 55 has a blue color that is different from the emission color of the light source 80 (here, white light), and the display panel 50 is sandwiched between the light transmission part 53 and the light guide part 100. It is located at the periphery of.

従って、光透過部53と着色層55とによって導光部100を光源80の発光色とは異なる色調に着色させることができ、光源80から発せられる照明光(白色光)が導光部材60を経て導光部100に供給された際には、導光部100に導光された照明光は青色(光源80の発光色とは異なる色調)に着色されるため、導光部100の着色光を導光部材60に備えられる後述する凸目盛部及び計測値表示部51の透過光に対して容易に異ならせることができる。なお、着色層55の色調は、光源80の発光色(白色)と異なる色調であれば、青色に限らず、あらゆる色調を適用することができる。   Therefore, the light transmission unit 53 and the colored layer 55 can color the light guide unit 100 in a color tone different from the emission color of the light source 80, and the illumination light (white light) emitted from the light source 80 causes the light guide member 60 to be colored. When the illumination light guided to the light guide unit 100 is colored blue (color tone different from the light emission color of the light source 80) when supplied to the light guide unit 100, the colored light of the light guide unit 100 is supplied. Can be easily made different from the transmitted light of the later-described convex scale portion provided in the light guide member 60 and the measured value display portion 51. Note that the color tone of the colored layer 55 is not limited to blue as long as the color tone is different from the light emission color (white) of the light source 80, and any color tone can be applied.

また、計測値表示部51と光透過部53との間に位置する背景部52箇所には、所定の間隔を有して略矩形状に開口形成される貫通孔からなる複数個の貫通部56が設けられている。これら複数個の貫通部56は、複数個の計測値表示部51に対応するようにそれぞれ設けられ、複数個の貫通部56からは、複数個の前記凸目盛部が視認者側に向けて突出している。   In addition, a plurality of through portions 56 each including a through hole formed in a substantially rectangular shape with a predetermined interval are provided at 52 background portions located between the measurement value display portion 51 and the light transmission portion 53. Is provided. The plurality of penetrating portions 56 are respectively provided so as to correspond to the plurality of measurement value display portions 51, and the plurality of convex scale portions protrude from the plurality of penetrating portions 56 toward the viewer side. ing.

Specifically, in this case, the fine uneven portion 57 is inside the penetrating portion 56 and corresponds to the arrangement position of an annular portion described later provided in the light guide member 60 and the measurement value display portion 51 and It consists of a substantially concentric Fresnel lens surface formed on the surface side of the background portion 52. The measurement value display unit 51 and the background unit 52 may be formed on the back surface of the substrate 54, and similarly, the colored layer 55 may be formed on the back surface of the light transmission unit 53 (substrate 54).

In addition, for the purpose of efficiently guiding illumination light emitted from the light source 80 through the standing wall portion 62, the inclined wall portion 63 and the annular portion 61 to the outer edge portion of the annular portion 61 mainly toward the light transmitting portion 53 side. A reflecting wall 61a having an inclined surface shape is formed.

立壁部62は、略すり鉢状の円筒体にて形成され、その下端面は光源80の発光面と対向している。光源80から発せられる照明光は、前記下端面を通じて立壁部62内に入射し、その後、傾斜壁部63を経て円環部61の前記外縁部分へと放射状に反射導光されるものである。   The standing wall portion 62 is formed of a substantially mortar-shaped cylindrical body, and the lower end surface thereof faces the light emitting surface of the light source 80. Illumination light emitted from the light source 80 enters the standing wall portion 62 through the lower end surface, and then is reflected and guided radially to the outer edge portion of the annular portion 61 through the inclined wall portion 63.

また、傾斜壁部63の表面側には、立壁部62内に入射した光源80からの照明光を円環部61へと反射導光させるための傾斜面形状からなる反射面63aが設けられている。   Further, on the surface side of the inclined wall portion 63, there is provided a reflecting surface 63a having an inclined surface shape for reflecting and guiding the illumination light from the light source 80 incident in the standing wall portion 62 to the annular portion 61.

When the illumination light is guided to the light guide unit 100, the light guide unit 100 emits blue light.

ケース体90は、例えば白色系の合成樹脂からなり、表示パネル50や導光部材60を保持する保持体としての機能、光源70や発光体80を収納するハウジングとしての機能、発光体80からの照明光を前方側に反射させる反射体としての機能を有している。   The case body 90 is made of, for example, a white synthetic resin, functions as a holding body that holds the display panel 50 and the light guide member 60, functions as a housing that houses the light source 70 and the light emitting body 80, and from the light emitting body 80. It has a function as a reflector that reflects the illumination light forward.

またケース体90は、発光体80を収納し指針40の前記回転中心部に発光体80からの照明光(赤色光)を供給するための筒状部91と、導光部材60の円環部61を保持する保持部92とを有している。   Further, the case body 90 accommodates the light emitter 80 and supplies a cylindrical portion 91 for supplying illumination light (red light) from the light emitter 80 to the rotation center portion of the pointer 40, and an annular portion of the light guide member 60. And a holding portion 92 that holds 61.

導光部100は、例えば無色透明の透光性合成樹脂からなり、略円環リング状に形成され、光透過部53に対応するように表示パネル50の前方側に配置(載置)されている。   The light guide unit 100 is made of, for example, a colorless transparent translucent synthetic resin, is formed in a substantially annular ring shape, and is disposed (placed) on the front side of the display panel 50 so as to correspond to the light transmission unit 53. Yes.

この導光部100には、光透過部53を透過した照明光を入射する入射面(入射部)101と、この入射面101を通じて導光部100内に導入された照明光を回転軸20側(凸目盛部64側)に向けて反射導光させるための傾斜面形状からなる反射部102と、この反射部102によって反射された照明光を凸目盛部64側に向けて出射させる出射面(出射部)103とが設けられている。   The light guide unit 100 includes an incident surface (incident unit) 101 on which illumination light transmitted through the light transmission unit 53 is incident, and illumination light introduced into the light guide unit 100 through the incident surface 101 on the rotating shaft 20 side. A reflecting portion 102 having an inclined surface shape for reflecting and guiding light toward the convex scale portion 64 side, and an emission surface for emitting the illumination light reflected by the reflecting portion 102 toward the convex scale portion 64 side ( And an emission unit 103.

反射部102は、本例の場合、複数個の凸目盛部64に対応するように導光部100に複数個設けられている。具体的には、個々の凸目盛部64の外側において、個々の凸目盛部64と隣接した状態で、個々の凸目盛部64に対応して個々の反射部102が断面略三角形状を有するように設けられている。従って、図4に示すように凸目盛部64の形成されていない領域に対応する導光部100の表面箇所には反射部102は形成されておらず、当該表面箇所の形状は平坦面(フラットな面)となっている。また、反射部102は、出射面103から出射される前記第2の照明光を凸目盛部64を通じて(介して)微細凹凸部57へと反射させる反射面を構成している。   In the case of this example, a plurality of reflecting portions 102 are provided in the light guide portion 100 so as to correspond to the plurality of convex scale portions 64. Specifically, outside the individual convex scale portions 64, the individual reflecting portions 102 have a substantially triangular cross section corresponding to the individual convex scale portions 64 in a state adjacent to the individual convex scale portions 64. Is provided. Therefore, as shown in FIG. 4, the reflecting portion 102 is not formed on the surface portion of the light guide portion 100 corresponding to the region where the convex scale portion 64 is not formed, and the shape of the surface portion is flat (flat). It has become a). Further, the reflecting portion 102 constitutes a reflecting surface that reflects the second illumination light emitted from the emitting surface 103 to the fine uneven portion 57 through (via) the convex scale portion 64.

装飾リング110は、ここでの詳細図示は省略するが、透光性合成樹脂材料にて形成された略L字状のリング本体部の表面全体に金属色調の表面処理が施された装飾部材からなり、導光部100を覆い隠すように構成されている。   Although the detailed illustration here is omitted, the decorative ring 110 is made of a decorative member in which the entire surface of a substantially L-shaped ring main body portion formed of a light-transmitting synthetic resin material is subjected to a surface treatment in a metal color tone. It is comprised so that the light guide part 100 may be covered.

このような構成において、光源80から発せられる照明光(白色光)は、上述のように立壁部62、傾斜壁部63、円環部61を経て円環部61の前記外縁部分へと放射状に反射導光される。この円環部61の前記外縁部分へと放射状に反射導光された白色光は、各凸目盛部64や各計測値表示部51へと白色光を導入する前記第1の照明光と、光透過部53へと白色光を導入する前記第2の照明光とに大別される。   In such a configuration, the illumination light (white light) emitted from the light source 80 radiates radially to the outer edge portion of the annular portion 61 through the standing wall portion 62, the inclined wall portion 63, and the annular portion 61 as described above. Reflected and guided. The white light that is radially reflected and guided to the outer edge portion of the annular portion 61 is light emitted from the first illumination light that introduces white light to each convex scale portion 64 and each measured value display portion 51, and light. It is roughly divided into the second illumination light that introduces white light into the transmission part 53.

そして、前記第1の照明光は、各凸目盛部64や各計測値表示部51へと白色光が導入されることで、各凸目盛部64と各計測値表示部51とが白色で発光する。   And the said 1st illumination light light-emits each convex scale part 64 and each measured value display part 51 in white by introducing white light into each convex scale part 64 and each measured value display part 51. To do.

一方、前記第2の照明光は、光透過部53へと白色光が導入された後、着色層55を透過する際に青色光となり、この青色光が入射面101を通じて導光部100の内部へと導入される。この導光部100の内部へと導入された青色光は、反射部102によって中心側(回転軸20側)に向けて反射され、凸目盛部64を通過した後、凸目盛部64の内壁面Pから表示パネル50に形成された微細凹凸部57に向けて青色出射光として出射される。   On the other hand, the second illumination light becomes blue light when white light is introduced into the light transmission part 53 and then passes through the colored layer 55, and this blue light passes through the incident surface 101 and enters the inside of the light guide part 100. Introduced into The blue light introduced into the light guide unit 100 is reflected by the reflecting unit 102 toward the center side (rotating shaft 20 side), passes through the convex scale part 64, and then the inner wall surface of the convex scale part 64. The light is emitted as blue emitted light from P toward the fine uneven portion 57 formed on the display panel 50.

この際、凸目盛部64の非形成領域に対応した導光部100の表面箇所には、反射部102が形成されていないことから、当該導光部100の表面箇所を通過する青色光は、その真上にある装飾リング110によって遮られるため、視認者側から視認されることはない。   At this time, since the reflective portion 102 is not formed on the surface portion of the light guide portion 100 corresponding to the non-formation region of the convex scale portion 64, the blue light passing through the surface portion of the light guide portion 100 is Since it is blocked by the decorative ring 110 located directly above, it is not visually recognized from the viewer side.

そして、着色層55によって青色に着色された後、導光部100と凸目盛部64とを経て微細凹凸部57へと至る前記青色出射光は、光学的拡大手段である微細凹凸部57での光反射作用によって、凸目盛部64に連なる(計測値表示部51と重なる)放射状の青色の虚像Vとなって視認者側から視認される(図1参照)。   Then, after being colored blue by the colored layer 55, the blue emitted light that reaches the fine concavo-convex part 57 through the light guide part 100 and the convex scale part 64 is emitted from the fine concavo-convex part 57 that is an optical expansion means. Due to the light reflection action, a radial blue virtual image V that is continuous with the convex scale portion 64 (overlaps with the measurement value display portion 51) is visually recognized from the viewer side (see FIG. 1).

この青色の虚像Vは、個々の凸目盛部64に連なるように凸目盛部64の内側に略線状に延びた線状光線となっており、この場合、速度計の中心点(回転軸20側)では、光線が尾を引くように延びた先細り状の線状光線となっている。また、凸目盛部64の長手方向に沿い、引き延ばされている(拡大している)かのごとく視認される線状光線である青色の虚像Vは、速度計の中心点(回転軸20側)を中心として見た場合、あたかも花火打ち上げ時の模様を模した放射状の装飾模様となっている。   This blue virtual image V is a linear ray extending substantially linearly inside the convex scale portion 64 so as to be continuous with each convex scale portion 64. In this case, the center point of the speedometer (the rotation axis 20). On the side), the light beam is a tapered linear light beam extending so as to have a tail. Further, the blue virtual image V, which is a linear ray that is visually recognized as if stretched (expanded) along the longitudinal direction of the convex scale portion 64, is a center point (rotation axis 20) of the speedometer. When viewed from the center), it looks like a radial decorative pattern imitating the pattern of fireworks.

ここで、凸目盛部64と微細凹凸部57との位置関係に着目すると、回転軸20側に向かうに従い、凸目盛部64の内壁面Pから微細凹凸部57までの距離差が次第に大きくなっている及び当該距離差が大きいほど微細凹凸部57にあたる光量が小さくなることに起因して、青色の虚像Vは、前記距離差が大きいほど、図5に示すように表示パネル50(基板54)の板面から奥まった位置にあるかのように視認者側から視認され、且つ、その濃淡が回転軸20側に向かうに従って(前記距離差が大きいほど)、淡くなるように視認されることから、新規(斬新)な見栄えを実現することが可能となる。   Here, paying attention to the positional relationship between the convex scale portion 64 and the fine uneven portion 57, the distance difference from the inner wall surface P of the convex scale portion 64 to the fine uneven portion 57 gradually increases toward the rotating shaft 20 side. As the distance difference is larger, the amount of light hitting the fine unevenness portion 57 is smaller. As the distance difference is larger, the blue virtual image V is larger in the display panel 50 (substrate 54) as shown in FIG. Since it is visually recognized from the viewer side as if it is in a position recessed from the plate surface, and it is visually recognized so as to become lighter as the density goes to the rotating shaft 20 side (the larger the distance difference), A new (new) appearance can be realized.

以上のように本実施形態では、所定の間隔を有して開口形成される複数個の貫通部56と貫通部56を包囲する光透過部53とが設けられた表示パネル50と、複数個の貫通部56に対応するように設けられる複数個の凸目盛部(透光部)63と、光透過部53に対応するように表示パネル50の前方側に配置される導光部100と、複数個の凸目盛部64に前記第1の照明光を供給するとともに光透過部53を通じて導光部100に前記第2の照明光を供給する光源80とを備え、貫通部56の内側となる表示パネル50の表面側には光学的拡大手段としての微細凹凸部57が設けられ、導光部100には、前記第2の照明光を凸目盛部64を介して微細凹凸部57へと反射させる反射部102が設けられているものである。また、反射部102は、複数個の透光部63に対応するように導光部100に複数個設けられ、微細凹凸部57、同心円状のフレネルレンズ面からなるものである。 As described above, in the present embodiment, the display panel 50 provided with the plurality of through portions 56 that are opened with a predetermined interval and the light transmitting portion 53 that surrounds the through portions 56, and the plurality of display panels 50 are provided. A plurality of convex scale portions (translucent portions) 63 provided so as to correspond to the penetrating portion 56, a light guide portion 100 disposed on the front side of the display panel 50 so as to correspond to the light transmissive portion 53, and a plurality of A light source 80 that supplies the first illumination light to each of the convex scale portions 64 and supplies the second illumination light to the light guide portion 100 through the light transmission portion 53, and displays inside the through portion 56. The surface 50 of the panel 50 is provided with a fine uneven portion 57 as an optical enlarging means, and the light guide portion 100 reflects the second illumination light to the fine uneven portion 57 via the convex scale portion 64. A reflection unit 102 is provided. A plurality of reflecting portions 102 are provided in the light guide portion 100 so as to correspond to the plurality of light transmitting portions 63, and the fine uneven portions 57 are formed of concentric Fresnel lens surfaces.

従って、従来のように2種類の光源ではなく単一(1つ)の光源80から発せられる白色光を利用して、表示パネル50の計測値表示部51と放射状に形成された青色の虚像Vとの双方を発光表示させることができ、しかも、青色の虚像Vは、前記距離差が大きいほど表示パネル50(基板54)の板面から奥まった位置にあるかのように視認者側から視認され、且つ、その濃淡が前記距離差が大きいほど淡くなるように視認されることから、コスト上昇を抑制しながら(光源の個数を必要最小限としつつ)新規な見栄えを実現することが可能な表示装置を提供することができる。   Therefore, the blue virtual image V formed radially with the measurement value display unit 51 of the display panel 50 using white light emitted from a single (one) light source 80 instead of two types of light sources as in the past. In addition, the blue virtual image V is visually recognized from the viewer side as if the distance difference is larger as it is located deeper from the plate surface of the display panel 50 (substrate 54). In addition, since it is visually recognized that the shading becomes lighter as the distance difference is larger, it is possible to realize a new appearance while suppressing an increase in cost (minimizing the number of light sources). A display device can be provided.

また本実施形態では、光透過部53には、光源80の発光色とは異なる色調を有する着色層55が形成されていることにより、導光部100に導光される前記第2の照明光を着色層55によって光源80の発光色(白色)とは異なる色に容易に着色することができ、計測値表示部51と導光部100とを異なる色で発光させる際に有利である。なお、着色層55は、必要に応じて廃止してもよく、この場合、放射状の虚像Vは、光源80の発光色である白色で発光表示される。   In the present embodiment, the light transmissive portion 53 is provided with the colored layer 55 having a color tone different from the emission color of the light source 80, so that the second illumination light guided to the light guide portion 100 is formed. Can be easily colored in a color different from the emission color (white) of the light source 80 by the colored layer 55, which is advantageous when the measured value display unit 51 and the light guide unit 100 emit light in different colors. The colored layer 55 may be abolished as necessary. In this case, the radial virtual image V is lit and displayed in white, which is the emission color of the light source 80.
