化粧板６ａは本実施形態では平板状であり、その中央部に表示素子７が露出する窓部６ｄを備えている。本実施形態では、窓部６ｄは貫通した孔であるが、例えば、化粧板６ｂを透明な合成樹脂から形成し、窓部６ｄに相当する部分を除いて遮光性の塗料を塗布し、窓部６が透明な部材で覆われたものであってもよい。   In this embodiment, the decorative plate 6a has a flat plate shape, and includes a window portion 6d through which the display element 7 is exposed at the center. In the present embodiment, the window portion 6d is a through-hole. For example, the decorative plate 6b is formed of a transparent synthetic resin, and a light-shielding paint is applied except for a portion corresponding to the window portion 6d. 6 may be covered with a transparent member.

また、カップ状の収納ケース６ａの背面には、後述する照射部６ｅを備えている。この照射部６ｅは、ケース体６の外部に照明装置８の光を出すものである。この照射部６ｅは窓部６ｄに対応する部分以外、すなわち、ケース体６の窓部６ｄ（化粧板６ａの板面方向）に対して垂直方向に、窓部６ｄを投影した部分以外に設けられている。照射部６ｅは、指針４の回動範囲に沿って、すなわち、窓部６ｄの周囲に、Ｃの字状に設けられている。図１中では、Ｃの字の切れ目が下方向に向いている。   Moreover, the back surface of the cup-shaped storage case 6a is provided with an irradiation unit 6e described later. The irradiation unit 6 e emits the light from the illumination device 8 to the outside of the case body 6. This irradiation part 6e is provided in a part other than a part corresponding to the window part 6d, that is, a part perpendicular to the window part 6d of the case body 6 (in the plate surface direction of the decorative board 6a) and a part projected from the window part 6d. ing. The irradiation part 6e is provided in a C shape along the rotation range of the pointer 4, that is, around the window part 6d. In FIG. 1, the C-shaped cut is directed downward.

表示素子７は、透過照明型の液晶表示素子である。照明装置８は光源８ａと導光体８ｂとからなり、光源８ａは、例えば、発光ダイオードである。また、導光体８ｂは光を透過可能な合成樹脂からなり、光源８ａの光を液晶表示素子７の背後に導くものである。なお、導光体８ａには、ケース体６の照射部６ｅに発光ダイオード８ａの光を反射する反射部８ｃを備えている。なお、１０は発光ダイオード８ａ用の補助回路基板である。なお、本実施形態では、ケース体６が表示素子７と照明装置８とを収納しているが、前記実施形態に限定されるものではなく、例えば、照明装置８を構成する光源８ａを回路基板９に設け、ケース体６は照明装置８を構成する導光体８ｂの一部を収納するものでもよい。   The display element 7 is a transmission illumination type liquid crystal display element. The illumination device 8 includes a light source 8a and a light guide 8b, and the light source 8a is, for example, a light emitting diode. The light guide 8b is made of a synthetic resin capable of transmitting light, and guides the light from the light source 8a to the back of the liquid crystal display element 7. The light guide 8a includes a reflecting portion 8c that reflects the light of the light emitting diode 8a on the irradiation portion 6e of the case body 6. Reference numeral 10 denotes an auxiliary circuit board for the light emitting diode 8a. In the present embodiment, the case body 6 accommodates the display element 7 and the illumination device 8. However, the case body 6 is not limited to the above embodiment. For example, the light source 8a constituting the illumination device 8 is a circuit board. 9, the case body 6 may accommodate a part of the light guide body 8 b constituting the lighting device 8.

文字板３は、光を透過可能な合成樹脂からなる。そして、本実施形態では、文字板３は、環状であり、その環状内に表示器２が位置している。また、文字板３の表面には遮光性の塗料からなる遮光層を備えている。この遮光層が、いわゆる文字板３の地の部分となる。また、文字板３の表面には、目盛や文字などからなる指標部３ａが設けられている。この指標部３ａは、表示器２の周囲に位置している。本実施形態では、指標部３ａは、前記遮光層を抜いて形成したものである。よって、指標部３ａは、文字板３の背後からの照明光によって、透過照明されるものである。   The dial 3 is made of a synthetic resin that can transmit light. In the present embodiment, the dial plate 3 has an annular shape, and the indicator 2 is located in the annular shape. Further, the surface of the dial 3 is provided with a light shielding layer made of a light shielding paint. This light shielding layer becomes a so-called ground portion of the dial 3. In addition, on the surface of the dial plate 3, an indicator portion 3 a made of scales or characters is provided. The indicator portion 3 a is located around the display device 2. In the present embodiment, the indicator portion 3a is formed by removing the light shielding layer. Therefore, the indicator part 3a is transmitted and illuminated by illumination light from behind the dial 3.

また、文字板３はすり鉢状で、環状の中央側が回路基板９側に近く、周辺部が回路基板９から離れた形状である。   The dial plate 3 has a mortar shape, and has an annular center side close to the circuit board 9 side and a peripheral part away from the circuit board 9.

指針４は、指示部４ａと固定部４ｂとから構成されている。指示部４ａは、文字板３の指標部３ａを指示するものであり、指針４の先端部およびその近傍を構成するものである。そして、指示部４ａは、透明な合成樹脂からなる導光部材からなる。固定部４ｂは、樹脂あるいは、金属からなり、指示部４ａを指示固定するものであり、駆動装置５の駆動軸５ａと指示部４ａとを連結するものである。指示部４ａと固定部４ｂとは容易に離れないように、強固に固定されている。また、固定部４ｂと駆動軸５ａとは、固定部４ｂに設けたボス部４ｃに駆動軸５ａを圧入して固定してある。   The pointer 4 includes an instruction unit 4a and a fixed unit 4b. The instructing unit 4a instructs the index unit 3a of the dial 3, and constitutes the tip of the pointer 4 and its vicinity. And the instruction | indication part 4a consists of a light guide member which consists of transparent synthetic resin. The fixing portion 4b is made of resin or metal, and indicates and fixes the indicating portion 4a. The fixing portion 4b connects the driving shaft 5a of the driving device 5 and the indicating portion 4a. The instruction portion 4a and the fixing portion 4b are firmly fixed so as not to be easily separated. The fixed portion 4b and the drive shaft 5a are fixed by press-fitting the drive shaft 5a into a boss portion 4c provided on the fixed portion 4b.

また、指示部４ａは、ケース体６の照射部６ｅからの光を受け取る受光部４ｄを備えており、指示部４ａは受光部４ｄで受けた光によって、照明される。   Moreover, the instruction | indication part 4a is provided with the light-receiving part 4d which receives the light from the irradiation part 6e of the case body 6, and the instruction | indication part 4a is illuminated by the light received by the light-receiving part 4d.

駆動装置５は、交差コイル式のムーブメントやステッピングモータなどが好適であり、前述した駆動軸５ａを介して、指針４を駆動するものである。   The drive device 5 is preferably a cross coil type movement or a stepping motor, and drives the pointer 4 via the drive shaft 5a described above.

回路基板９は、硬質の回路基板であり、例えば、基材にガラスエポキシ樹脂を用いている。また、その表面や裏面などには、銅などの導電材料からなる図示しない配線パターンが設けられている。   The circuit board 9 is a hard circuit board. For example, a glass epoxy resin is used as a base material. Further, a wiring pattern (not shown) made of a conductive material such as copper is provided on the front surface or the back surface.

以上のように、ケース体６の窓部６ｄに対応する部分以外のケース体６の背面に、指針４に照明装置８の光を照射する照射部６ｅを設けたことによって、窓部６ｄ（言い換えれば、表示素子７）に対応する部分の輝度が不均一になることを抑制し、均一な輝度の表示器を備えた指針式計器装置１を提供することができる。   As described above, by providing the irradiation part 6e for irradiating the light of the illumination device 8 on the pointer 4 on the back surface of the case body 6 other than the part corresponding to the window part 6d of the case body 6, the window part 6d (in other words, For example, it is possible to provide a pointer-type instrument device 1 that is provided with a display device having a uniform brightness by suppressing the brightness of the portion corresponding to the display element 7) from becoming uneven.

また、本発明は、指針４の先端部およびその近傍を導光部材としたことによって、指針４を照明する光を指針４の駆動軸５ａから指針４の先端へ導くために、指針４が大型化して重量が増加することを抑制することができる。さらに、この軽量化に伴う指針の応答性の向上や、高トルクの駆動装置５への変更を防止することができ、コストの上昇を抑制することができる。   Further, according to the present invention, since the tip portion of the pointer 4 and the vicinity thereof are light guide members, the pointer 4 is large in size to guide the light illuminating the pointer 4 from the drive shaft 5a of the pointer 4 to the tip of the pointer 4. It is possible to prevent the weight from increasing. Furthermore, the improvement of the responsiveness of the pointer accompanying this weight reduction and the change to the high torque drive device 5 can be prevented, and an increase in cost can be suppressed.

また、照射部６ｅをケース体６の背面に設けたことによって、ケース体６からの光は、駆動装置５側に照射されるので、駆動軸５ａを中心とし、駆動軸５ａと垂直方向に交わる方向に光が拡散することが抑制できるので、照射部６ｅからの光が文字板３に漏れることがなく、文字板３を表示装置２より回路基板９側に設けても、照射部６ｅからの光が文字板３に漏れることがなく、本実施形態のように、文字板３の内周部分をケース体６の化粧板６ｂよりも回路基板９側に位置させることができ、文字板３と表示装置２との位置関係を違えて、立体的な表示を行うこともできる。   Further, since the irradiation unit 6e is provided on the back surface of the case body 6, light from the case body 6 is irradiated to the driving device 5 side, and thus intersects the driving shaft 5a in the vertical direction with the driving shaft 5a as the center. Since light can be prevented from diffusing in the direction, light from the irradiation unit 6e does not leak to the dial plate 3, and even if the dial plate 3 is provided on the circuit board 9 side from the display device 2, the light from the irradiation unit 6e Light does not leak into the dial plate 3, and the inner peripheral portion of the dial plate 3 can be positioned closer to the circuit board 9 than the decorative plate 6 b of the case body 6 as in the present embodiment. A three-dimensional display can be performed by changing the positional relationship with the display device 2.

次に本発明の第２実施形態を、図３を用いて説明する。なお、前記第１実施形態と同一および相当個所には同一符号を付して、その詳細な説明は省略する。   Next, a second embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same part as said 1st Embodiment, and an equivalent part, and the detailed description is abbreviate | omitted.

ケース体１６のカップ状の収納ケース１６ａの側面には、後述する照射部１６ｅを備えている。この照射部１６ｅは、ケース体１６の外部に照明装置８の光を出すものである。この照射部１６ｅは窓部１６ｄに対応する部分以外、すなわち、ケース体１６の窓部１６ｄ（化粧板６ａの板面方向）に対して垂直方向に、窓部１６ｄを投影した部分以外に設けられている。   The side surface of the cup-shaped storage case 16a of the case body 16 is provided with an irradiation unit 16e described later. The irradiation unit 16 e emits light from the lighting device 8 to the outside of the case body 16. This irradiating portion 16e is provided at a portion other than the portion corresponding to the window portion 16d, that is, other than the portion where the window portion 16d is projected in a direction perpendicular to the window portion 16d of the case body 16 (plate surface direction of the decorative plate 6a). ing.

また、指針１４は、第１実施形態に対して、指示部１４ａのみが異なる形状であり、ケース体１６の側面に設けた照射部１６ｅに対応して、第１実施形態の受光部４ｄの位置とは、受光部１４ｄの位置が異なっている。   Further, the pointer 14 has a shape that is different from the first embodiment only in the instruction unit 14a, and corresponds to the position of the light receiving unit 4d of the first embodiment corresponding to the irradiation unit 16e provided on the side surface of the case body 16. Is different from the position of the light receiving portion 14d.

前記実施形態では、文字板３はすり鉢形状であったが、本実施形態では、文字板１３は平板状であり、ケース体１６の化粧版１６ｂと、同一平面を構成している。これは、ケース体１６の照射部１６ｅから漏れた光によって、文字板１３が照明されないようにするものである。なお、文字板１３が照射部１６ｅから漏れた光によって、文字板１３が照明されないのなら、文字板１３と化粧板１６ｂとを同一平面を構成する必要はない。逆に、照射部１６ｅからの光で積極的に文字板１３を照明する場合は、第１の実施形態の文字板３を採用してもよい。   In the embodiment, the dial plate 3 has a mortar shape. However, in the present embodiment, the dial plate 13 has a flat plate shape and forms the same plane as the decorative plate 16 b of the case body 16. This is to prevent the dial 13 from being illuminated by the light leaked from the irradiation part 16e of the case body 16. In addition, if the dial 13 is not illuminated by the light leaked from the irradiation part 16e, the dial 13 and the decorative board 16b do not need to comprise the same plane. Conversely, when the dial 13 is actively illuminated with the light from the irradiation unit 16e, the dial 3 of the first embodiment may be employed.

以上のように、ケース体１６の窓部１６ｄに対応する部分以外のケース体１６の側面に、指針４に照明装置８の光を照射する照射部１６ｅを設けたことによって、窓部１６ｄ（言い換えれば、表示素子７）に対応する部分の輝度が不均一になることを抑制し、均一な輝度の表示器を備えた指針式計器装置１を提供することができる。   As described above, by providing the irradiation part 16e that irradiates the pointer 4 with the light of the illumination device 8 on the side surface of the case body 16 other than the part corresponding to the window part 16d of the case body 16, the window part 16d (in other words, For example, it is possible to provide a pointer-type instrument device 1 that is provided with a display device having a uniform brightness by suppressing the brightness of the portion corresponding to the display element 7) from becoming uneven.
