（ケース体）
つづいて、図５，図６を用いて本実施形態におけるケース体２０を説明する。図５は、ケース体２０の正面図であり、図６は、本実施形態における表示装置１の断面図であり、図４のＡ−Ａ’断面図である。 (Case body)
Next, the case body 20 in the present embodiment will be described with reference to FIGS. FIG. 5 is a front view of the case body 20, and FIG. 6 is a cross-sectional view of the display device 1 in the present embodiment, and is a cross-sectional view taken along line AA ′ of FIG. 4.

ケース体２０は、例えば白色の合成樹脂材料からなり、導光文字板１０と後述する回路基板５０との間に配設され、導光文字板１０を支持固定するものである。
ケース体２０は、図５に示すように、第１光源６１及び導光体３０を区画する貫通孔からなる第１仕切り部２１と、導光文字板１０を載置する載置部２２と、第１仕切り部２１のうち、導光文字板１０の第１光透過射出部１２１がない方向に形成され、載置部２２より表側（視認者側）に突設した第１遮光壁２３と、第１仕切り部２１を中心として円弧状に形成され、載置部２２より表側に突設した第２遮光壁２４と、この第２遮光壁２４同士の間の隙間である切り欠き部２４ａと、切り欠き部２４ａの隙間を阻むように配設された第３遮光壁２５と、外側表示領域Ｅ２に配設される第２光源６２を区画する貫通孔からなる第２仕切り部２６と、内側表示領域Ｅ１に配設される第３光源６３を区画する貫通孔からなる第３仕切り部２７と、液晶パネルなどの表示器９０を挿入する貫通孔からなる表示器装着孔２８と、を有するものである。 The case body 20 is made of, for example, a white synthetic resin material, and is disposed between the light guide dial plate 10 and a circuit board 50 described later, and supports and fixes the light guide dial plate 10.
As shown in FIG. 5, the case body 20 includes a first partition portion 21 including a through hole that partitions the first light source 61 and the light guide body 30, a placement portion 22 on which the light guide dial 10 is placed, A first light shielding wall 23 that is formed in a direction in which the first light transmitting and emitting part 121 of the light guide dial 10 is not present in the first partition part 21 and projects from the mounting part 22 to the front side (viewer side); A second light-shielding wall 24 formed in an arc shape centering on the first partition part 21 and protruding from the mounting part 22 on the front side; and a notch 24a that is a gap between the second light-shielding walls 24; A third light shielding wall 25 disposed so as to block the gap between the cutout portions 24a, a second partition portion 26 including a through hole that divides the second light source 62 disposed in the outer display region E2, and an inner display region A third partition portion 27 comprising a through hole that divides the third light source 63 disposed in E1, and a liquid A display mounting hole 28 of the through-holes for inserting the indicator 90, such as a panel, and has a.

第１仕切り部２１は、図６に示すように、貫通孔で形成され、第１光源６１及び導光体３０を区画するものであり、第１光源６１から発せられる光及び導光体３０から漏れた光を反射するものである。 As shown in FIG. 6, the 1st partition part 21 is formed with a through-hole, and divides the 1st light source 61 and the light guide 30, The light emitted from the 1st light source 61 and the light guide 30 It reflects the leaked light.

載置部２２は、導光文字板１０及び回路基板５０と略平行になるように形成され、導光文字板１０の裏面と接触した状態で導光文字板１０を保持するものである。また、載置部２２は、導光文字板１０の裏面側から漏れる第１の光Ｌａを反射し、導光文字板１０内に第１の光Ｌａとして戻し、導光文字板１０内を進行する第１の光Ｌａが第１光透過射出部１２１以外から抜けてしまうのを防止する。 The mounting portion 22 is formed so as to be substantially parallel to the light guide dial plate 10 and the circuit board 50, and holds the light guide dial plate 10 in contact with the back surface of the light guide dial plate 10. The mounting portion 22 reflects the first light La leaking from the back surface side of the light guide dial 10, returns it as the first light La into the light guide dial 10, and travels through the light guide dial 10. This prevents the first light La to escape from other than the first light transmitting and emitting part 121.

第１遮光壁２３は、第１仕切り部２１のうち、導光文字板１０の第１光透過射出部１２１が配設されない領域（第２内側表示領域Ｅ１ｂ）に載置部２２より表側に突設するものであり、後述する導光体３０の文字板方向射出部３４から導光文字板１０の内壁入光部１１１ａへ射出する第１の光Ｌａを遮断するものである。第１遮光壁２３は、第１の光Ｌａを導光体３０側へ反射するように反射部材で形成されることが望ましい。
第１遮光壁２３は、表示装置１の組み付けにより同様の位置に配設されるものであれば、ケース体２０とは異なる部材としてもよい。例えば、指針４０を照明した際に発生するハレーションを防止するカラー部材（図示しない）により形成されてもよい。 The first light shielding wall 23 protrudes from the mounting portion 22 to the front side in the region (second inner display region E1b) in the first partition portion 21 where the first light transmission and emission portion 121 of the light guide dial plate 10 is not provided. The first light La emitted from the dial direction emitting portion 34 of the light guide 30 to be described later to the inner wall light incident portion 111a of the light guide dial 10 is blocked. The first light shielding wall 23 is desirably formed of a reflective member so as to reflect the first light La toward the light guide 30 side.
The first light shielding wall 23 may be a member different from the case body 20 as long as the first light shielding wall 23 is disposed at the same position by the assembly of the display device 1. For example, it may be formed of a collar member (not shown) that prevents halation that occurs when the pointer 40 is illuminated.

第２遮光壁２４は、第１仕切り部２１を中心として円弧状に形成され、載置部２２より表側に突設し、導光文字板１０の第１挿入部１１２に挿入されるものである。
第２遮光壁２４のうち、第１内側表示領域Ｅ１ａに含まれる領域には、図６に示すように、導光文字板１０内を進行する第１の光Ｌａを反射光Ｌｄとして反射する第１の反射面２４ｐを有する。第１の反射面２４ｐは、第１の光Ｌａを反射光Ｌｄとして導光文字板１０の方向へ反射し、この反射光Ｌｄが第１光透過射出部１２１から射出されることにより、第１光透過射出部１２１をより明るく光輝させることができる。
また、第２遮光壁２４のうち、第２内側表示領域Ｅ１ｂに含まれる領域には、導光文字板１０内を進行する第１の光Ｌａを反射光Ｌｄとして反射させない第１の非反射面（図示しない）を有する。第１の非反射面は、第２遮光壁２４を暗色系に着色することにより形成され、第１の光Ｌａを反射光Ｌｄとして導光文字板１０方向へ反射させないことにより、第２内側表示領域Ｅ１ｂに配設される第３光透過射出部１２３及び表示窓１２４から反射光Ｌｄが射出されるのを防止し、第３光透過射出部１２３及び表示窓１２４が光輝してしまうのを抑制することができる。 The second light shielding wall 24 is formed in an arc shape with the first partition portion 21 as the center, protrudes from the mounting portion 22 on the front side, and is inserted into the first insertion portion 112 of the light guide dial 10. .
As shown in FIG. 6, the second light shielding wall 24 includes a first light La that travels in the light guide dial 10 as reflected light Ld in a region included in the first inner display region E1a. 1 reflective surface 24p. The first reflecting surface 24p reflects the first light La as reflected light Ld in the direction of the light guide dial plate 10, and the reflected light Ld is emitted from the first light transmitting and emitting unit 121, so that the first light La is reflected. The light transmissive emission part 121 can be made to shine brighter.
In addition, in the second light shielding wall 24, a region included in the second inner display region E <b> 1 b is a first non-reflecting surface that does not reflect the first light La traveling in the light guide dial 10 as the reflected light Ld. (Not shown). The first non-reflective surface is formed by coloring the second light-shielding wall 24 in a dark color system, and does not reflect the first light La as reflected light Ld in the direction of the light guide dial 10, thereby providing a second inner display. The reflected light Ld is prevented from being emitted from the third light transmitting and emitting part 123 and the display window 124 disposed in the region E1b, and the third light transmitting and emitting part 123 and the display window 124 are prevented from shining. can do.

切り欠き部２４ａは、第２遮光壁２４同士の間の隙間であり、この切り欠き部２４ａを設けることにより、導光文字板１０に連結部１１２ａを設けることができ、導光文字板１０において、内側表示領域Ｅ１と外側表示領域Ｅ２とを連結部１１２ａにより連結させることができる。
切り欠き部２４ａは、後述する遠方意匠補正部１２１ｄ近傍を避けて配設される。斯かる構成により、切り欠き部２４ａによって反射光Ｌｄの光量が、第１遮光壁２３による反射光Ｌｄの光量よりも小さくなってしまうことに起因して、遠方意匠補正部１２１ｄの輝度が部分的に低下してしまうのを抑制することができる。 The notch 24a is a gap between the second light shielding walls 24. By providing the notch 24a, the light guide dial 10 can be provided with the connecting portion 112a. The inner display area E1 and the outer display area E2 can be connected by the connecting portion 112a.
The cutout portion 24a is disposed avoiding the vicinity of the distant design correcting portion 121d described later. With such a configuration, the brightness of the distant design correction unit 121d is partially reduced because the light amount of the reflected light Ld becomes smaller than the light amount of the reflected light Ld by the first light shielding wall 23 by the notch 24a.

The light guide 30 includes a storage unit 31 that stores a first light source 61, which will be described later, and a dial direction reflection unit 32 that reflects the light of the first light source 61 in the direction of the inner wall light incident part 111a of the light guide dial 10. A pointer direction emitting portion 33 for emitting the fourth light Le in the direction of the pointer 40, a dial direction emitting portion 34 for emitting the first light La to the inner wall light incident portion 111a of the light guide dial 10, and A pointer shaft insertion portion 35 through which the pointer shaft 71 is inserted, and guides the light from the first light source 61 to the light guide dial plate 10 and the pointer 40. In the present specification and drawings, the light guided from the first light source 61 toward the light guide dial 10 by the light guide 30 is the first light La, and the same light guide. The light guided in the direction of the pointer 40 by 30 is expressed as the fourth light Le.

文字板方向反射部３２は、図７（ｂ）に示すように、導光体３０の中心Ｏを軸とした双曲面などの曲面形状で形成され、収納部３１から入射した光を、第１の光Ｌａとして文字板方向射出部３４の方向へ反射する。本実施例においては、文字板方向反射部３２は、導光体３０の中心Ｏを中心とし、略全方向に設けられているが、光を反射させたい領域によって、適宜、文字板方向反射部３２を設ける領域を限定してもよい。
また、文字板方向反射部３２は、図７（ｃ）に示すように、円錐状や角錐面状（六角錐面，八角錐面等）に形成してもよい。 As shown in FIG. 7B, the dial direction reflecting portion 32 is formed in a curved surface shape such as a hyperboloid with the center O of the light guide 30 as an axis, and the light incident from the storage portion 31 is converted into a first shape. The light La is reflected in the direction of the dial direction emitting portion 34. In the present embodiment, the dial direction reflecting portion 32 is provided in almost all directions with the center O of the light guide 30 as the center. However, the dial direction reflecting portion is appropriately selected depending on the region where light is to be reflected. The region where 32 is provided may be limited.

The thickness of the dial direction emitting portion 34, which is the height direction of the light guide 30, is formed to be substantially the same as the thickness of the inner wall light incident portion 111a. With such a configuration, light leakage during transmission of light from the light guide 30 to the light guide dial 10 can be suppressed, and the design can be efficiently illuminated.

指針軸挿通部３５は、後述する指針軸７１が挿通する部分であり、導光体３０の中心Ｏに貫通孔として設けられる。斯かる構成により、文字板方向射出部３４を略全方向へ設けることができ、光源からの光を、指針軸挿通部３５を中心に導光文字板１０の略全方向に対し射出することができ、より広範囲の意匠を効率よく照明することができる。
また、指針軸挿通部３５は、導光体３０の中心Ｏを中心とするものではなく、導光体３０の中心Ｏからオフセットした位置に設けられてもいい。 The pointer shaft insertion portion 35 is a portion through which a later-described pointer shaft 71 is inserted, and is provided as a through hole in the center O of the light guide 30. With such a configuration, the dial direction emitting portion 34 can be provided in almost all directions, and light from the light source can be emitted in almost all directions of the light guide dial 10 around the pointer shaft insertion portion 35. It is possible to illuminate a wider range of designs efficiently.

The pointer shaft 71 is located at the approximate center of the pointer shaft insertion hole 111 of the light guide dial plate 10 and passes therethrough, and the tip portion thereof projects upward from the display surface of the light guide dial plate 10.

装飾部材８０は、導光文字板１０の前面側に配設され、図４，図６に示すように、導光文字板１０の第１挿入部１１２及び第２挿入部１１３を覆う遮光性のリング形状の部材であり、導光文字板１０内を進行する第１の光Ｌａが、第１挿入部１１２及び第２挿入部１１３から漏れ出てしまった際に、視認者にその漏れ出た光を視認させないようにするものであり、照明の商品性を高めることができる。以上が、本実施形態における表示装置１の構成であり、以下に、導光文字板１０の表示装置１における作用と具体的構成について説明する。 The decorative member 80 is disposed on the front surface side of the light guide dial plate 10 and has a light shielding property to cover the first insertion portion 112 and the second insertion portion 113 of the light guide dial plate 10 as shown in FIGS. When the first light La that is a ring-shaped member and travels through the light guide dial 10 leaks from the first insertion portion 112 and the second insertion portion 113, the first light La leaks to the viewer. This prevents light from being visually recognized, and can increase the merchantability of illumination. The above is the configuration of the display device 1 in the present embodiment, and the operation and specific configuration of the light guide dial plate 10 in the display device 1 will be described below.

Then, it is formed by painting or painting.

透光部１２ｂは、遮光部１２ａを切り抜いた意匠の部分であり、透光性のインク等を用いて、印刷，塗装などによって形成される。また、透光部１２ｂは、遮光部１２ａと異なる色で形成し、光源からの光が射出されなくても意匠を視認できるようにしてもよい。また、透光部１２ｂを有色とすることで、透過した光を着色することができる。透光部１２ｂは、上述したように、導光文字板１０内を進行する第１光源６１が射出する第１の光Ｌａにより光輝する第１光透過射出部１２１と、導光文字板１０の裏面に配設される第２光源６２が射出する第２の光Ｌｂに照明されて光輝する第２光透過射出部１２２と、導光文字板１０の内側表示領域Ｅ１内の裏面に配設される第３光源６３が射出する第３の光Ｌｃに照明されて光輝する第３光透過射出部１２３と、表示器９０を視認可能にする表示窓１２４と、に設けられ、これらの透光部１２ｂから光を射出することにより、意匠（文字、絵、図形、記号等）を、視認者に対して表示する。
また、透光部１２ｂは、無色透明インクの印刷でもよく、また、遮光部１２ａを設けず透光性インクを印刷しない領域であってもよい。 The translucent portion 12b is a design portion obtained by cutting out the light shielding portion 12a, and is formed by printing, painting, or the like using translucent ink or the like. Moreover, the translucent part 12b may be formed in a color different from that of the light-shielding part 12a so that the design can be visually recognized without light emitted from the light source. Moreover, the light which permeate | transmitted can be colored by making the translucent part 12b colored. As described above, the translucent part 12 b includes the first light transmissive emission part 121 that shines by the first light La emitted from the first light source 61 that travels in the light guide dial 10, and the light guide dial 10.

Further, the translucent portion 12b may be printed with colorless and transparent ink, or may be an area where the light-shielding portion 12a is not provided and the translucent ink is not printed.

光拡散部１３は、光拡散性を有する材料を用いて、印刷、塗装等によって導光部１１の前面及び裏面上に形成され、導光部１１が導光した第１の光Ｌａを拡散する。光拡散部１３は、明るく視認させたい第１光透過射出部１２１（図３（ａ）における後述する指標意匠部１２１ａ及び遠方意匠部１２１ｃに対応する位置に設けられる。 The light diffusing unit 13 is formed on the front and back surfaces of the light guide unit 11 by printing, painting, or the like using a material having light diffusibility, and diffuses the first light La guided by the light guide unit 11. . The light diffusing unit 13 is provided at a position corresponding to an index design unit 121a and a distant design unit 121c, which will be described later, in the first light transmission and emission unit 121 (FIG. 3A) to be viewed brightly.

表面光調整部１４及び裏面光調整部１５は、導光部１１を挟んで、導光部１１の両面全体に亘って、その両面（適宜、光拡散部１３を含む）を覆うように設けられる。表面光調整部１４及び裏面光調整部１５は、透明又は半透明の透光性（半透光性を含む）を有し、導光部１１よりも光の屈折率が低い合成樹脂等を用いて、印刷、塗装等によって形成される低屈折率部材（図示しない）と光拡散性を有する拡散部材（図示しない）とで形成され、これら低屈折率部材と拡散部材とが印刷される面積割合に応じて、導光部１１内を反射する光の量及び導光部１１外に射出される光の量を調整する。低屈折率部材の面積割合を多くすると、導光部１１内を反射する光の量が多くなり、拡散部材の面積割合を多くすると、導光部１１外に射出される光の量が多くなる。 The front surface light adjustment unit 14 and the back surface light adjustment unit 15 are provided so as to cover both surfaces (including the light diffusion unit 13 as appropriate) across the entire surface of the light guide unit 11 with the light guide unit 11 interposed therebetween. The front surface light adjusting unit 14 and the back surface light adjusting unit 15 have a transparent or translucent translucency (including translucent property) and use a synthetic resin having a lower refractive index of light than the light guide unit 11. Formed by a low refractive index member (not shown) formed by printing, painting, and the like and a diffusion member (not shown) having light diffusibility, and the ratio of the area where the low refractive index member and the diffusion member are printed Accordingly, the amount of light reflected inside the light guide unit 11 and the amount of light emitted outside the light guide unit 11 are adjusted. Increasing the area ratio of the low refractive index member increases the amount of light reflected inside the light guide unit 11, and increasing the area ratio of the diffusion member increases the amount of light emitted outside the light guide unit 11. .

表面光調整部１４及び裏面光調整部１５は、光を射出する必要のない遮光部１２ａの裏面に設けられる場合、光を導光部１１外へ射出する必要はないので、低屈折率部材により形成し、拡散部材を設けないが、後述する表示面積の大きい加飾意匠部１２１ｂのように若干光輝させて表示させたい場合、図５（ａ）に示すように、遮光部１２ａを前面側に形成せずに（または若干透過する位に印刷し）、低屈折率部材に対する拡散部材の面積割合を増大させることで、導光部１１から少量の第１の光Ｌａを取り出し、加飾意匠部１２１ｂを低い輝度で光輝させる。 When the front surface light adjustment unit 14 and the rear surface light adjustment unit 15 are provided on the back surface of the light shielding unit 12a that does not need to emit light, the light does not need to be emitted outside the light guide unit 11, and thus is formed of a low refractive index member. However, when a diffusing member is not provided, but when it is desired to make the display slightly shiny like a decorative design portion 121b having a large display area, which will be described later, a light shielding portion 12a is formed on the front side as shown in FIG. Without printing (or printing slightly transparent), by increasing the area ratio of the diffusing member to the low refractive index member, a small amount of the first light La is taken out from the light guide unit 11, and the decorative design unit 121b Shine with low brightness.

Therefore, the second light Lb emitted from the second light source 62 is directly emitted without being diffused or reflected, so that it can be displayed with high brightness and can be noticed by the user.

第３光透過射出部１２３は、第２内側表示領域Ｅ１ｂに配設される意匠表示部であり、第２光透過射出部１２２と同様に、導光文字板１０の裏面に位置する第３光源６３から射出される第３の光Ｌｃを透過するものであり、第３光源６３から射出された第３の光Ｌｃが拡散や反射等されずに直接射出されるので、高輝度で表示でき、ユーザの目を引くことができる。 The third light transmission / emission part 123 is a design display part arranged in the second inner display area E1b, and, like the second light transmission / emission part 122, a third light source located on the back surface of the light guide dial plate 10. The third light Lc emitted from the third light source 63 is transmitted, and the third light Lc emitted from the third light source 63 is directly emitted without being diffused or reflected, so that it can be displayed with high brightness. The user's eyes can be caught.

遠方意匠補正部１２１ｄに対応して設けられる補正光拡散部１３ａの入光部１１１ａに向かう方向の幅Ｄ１１（図８（ａ））は、遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃに対応して設けられる光拡散部１３の入光部１１１ａ方向の幅Ｄ２１（（図８（ｂ）））より太くなるように形成される。
さらに、遠方意匠補正部１２１ｄの表面に設けられる透光部１２ｂの幅Ｆ１１は、遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃの表面側に設けられる透光部１２ｂの幅Ｆ２１と同じ太さになるように形成する。斯かる構成により、遠方意匠補正部１２１ｄは、補正光拡散部１３ａにより、他の光拡散部１３より広い範囲に第１の光Ｌａを多く射出させることができるため、導光される光量が少ない箇所（遠方意匠補正部１２１ｄ）でも、他の箇所（遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃ）同様に明るく視認させることができ、視認される線状の意匠の太さも他の箇所の太さ同様に視認させることができ、意匠の見栄えを良好にすることができる。また、遠方意匠補正部１２１ｄの透光部１２ｂの幅Ｆ１１と遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃの透光部１２ｂの幅Ｆ２１が略同一なので、第１光源６１が点灯しない場合、略同幅の透光部１２ｂが視認されることになり、昼間など遠方意匠部１２１ｃを光輝させない場合でも、視認される遠方意匠補正部１２１ｄの太さも他の箇所（遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃ）の太さと同等に視認させることができる。 The width D11 (FIG. 8 (a)) in the direction toward the light incident portion 111a of the correction light diffusion portion 13a provided corresponding to the far design correction portion 121d corresponds to the far design portion 121c other than the far design correction portion 121d. The light diffusing unit 13 is formed to be thicker than the width D21 ((FIG. 8B)) in the direction of the light incident unit 111a.
Furthermore, the width F11 of the translucent part 12b provided on the surface of the remote design correction part 121d is the same thickness as the width F21 of the translucent part 12b provided on the surface side of the far design part 121c other than the far design correction part 121d. It forms so that it may become. With such a configuration, the far-field design correcting unit 121d can emit a large amount of the first light La in a wider range than the other light diffusing units 13 by the correcting light diffusing unit 13a. Even in the location (distant design correction unit 121d), it can be viewed brightly in the same manner as in other locations (distant design correction unit 121c other than the remote design correction unit 121d), and the thickness of the visually recognized linear design is also the thickness of the other location. Similarly, it can be visually recognized, and the appearance of the design can be improved. Moreover, since the width F11 of the translucent part 12b of the distant design correcting part 121d and the width F21 of the translucent part 12b of the distant design correcting part 121c other than the distant design correcting part 121d are substantially the same, when the first light source 61 is not turned on, it is substantially omitted. The translucent portion 12b having the same width is visually recognized, and even when the far-end design portion 121c is not brilliant, such as in the daytime, the thickness of the far-end design correction portion 121d that is visible is also different from other locations (far away from the far-end design correction portion 121d.

また、このような構成において、遠方意匠部１２１ｃを光輝させずに視認する場合、遠方意匠補正部１２１ｄとこの遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃの太さが異なって視認されてしまうが、導光文字板１０の表側に光透過率の低いスモーク部材などからなる光調整パネルを設けることにより、遠方意匠部１２１ｃを光輝させないときは、この遠方意匠部１２１ｃを視認しづらくし、視認者が感じる遠方意匠補正部１２１ｄとこの遠方意匠補正部１２１ｄ以外の遠方意匠部１２１ｃの太さの違いを感じにくくすることができる。 Further, in the distant design correction unit 121d, as shown in FIG. 10A, the width D13 of the correction light diffusion unit 13a toward the light incident unit 111a and the direction of the light transmission unit 12b toward the light incident unit 111a.

You may form so that D23 and the width | variety F23 of the direction which goes to the light-incidence part 111a of the translucent part 12b may become equivalent.
Further, in such a configuration, when the far-end design portion 121c is viewed without shining, the far-end design correction portion 121d and the far-end design portion 121c other than the far-end design correction portion 121d are viewed with different thicknesses. By providing a light adjustment panel made of a smoke member having a low light transmittance on the front side of the light guide dial plate 10, when the distant design portion 121c is not brilliant, it is difficult to visually recognize the distant design portion 121c. It is possible to make it difficult to feel the difference in thickness between the distant design correction unit 121d and the distant design correction unit 121d other than the distant design correction unit 121d.
