Among such instrument devices, an analog instrument device using a pointer includes a type in which the pointer is shined by light from a light source (see, for example, Patent Document 1).

特許文献1に記載された計器装置は、表示意匠としての目盛が形成された文字板と、文字板の裏面側に配されたメイン基板と、文字板の前面側に配されてメイン基板と接続された補助基板と、文字板と補助基板との間に配された指針と、を備えている。指針は、補助基板上の内機の出力軸に取り付けられ、回転して表示意匠を指示する。このように、特許文献1に記載された計器装置は、内機を補助基板上に設けて文字板の前面側の既存のスペースに配することで、小型化(薄型化)を実現している。   The instrument device described in Patent Document 1 includes a dial plate with a scale as a display design, a main board arranged on the back side of the dial board, and a main board arranged on the front side of the dial board. And a pointer disposed between the dial and the auxiliary board. The pointer is attached to the output shaft of the internal unit on the auxiliary board and rotates to indicate the display design. As described above, the instrument device described in Patent Document 1 achieves downsizing (thinning) by providing the internal unit on the auxiliary board and arranging it in the existing space on the front side of the dial. .

また、前述した計器装置においては、補助基板の裏面に設けられた指針用光源によって指針を光輝させている一方、文字板(の目盛)を光輝させる文字板用光源が設けられていないので、周囲の状況によっては目盛の視認性が低下する虞があった。   Moreover, in the above-described instrument device, the pointer light source is shined by the pointer light source provided on the back surface of the auxiliary board, while the dial light source for shining the dial is not provided. Depending on the situation, the visibility of the scale may be reduced.

The scale 32 on the dial 31 is indicated. The base end portion 4 a is opposed to the pointer LED 37.

そして、指針用LED37の光は、図4中に一点鎖線で示すように、受光面42aから受光部42内に入射して反射面42bによって指示部43に向かって反射された後、指示部43内を進んで指示部43の露出孔46aから露出した部分から乗員に向かって放射される。こうして、乗員は、指針用LED37の光によって光輝した指針4を視認する。   Then, as indicated by the alternate long and short dash line in FIG. 4, the light from the pointer LED 37 enters the light receiving unit 42 from the light receiving surface 42 a and is reflected toward the indicating unit 43 by the reflecting surface 42 b, and then the indicating unit 43. The light is emitted toward the occupant from the portion exposed through the exposure hole 46a of the pointing portion 43. In this way, the occupant visually recognizes the pointer 4 shined by the light of the pointer LED 37.

導光板5は、透光性を有した合成樹脂(透光性材料)で構成され、図8に示すように、導光部51と受光部52とを一体に備えている。導光部51は、平面視C字状(馬蹄形状)の平板状に形成されている。導光部51は、外縁部が文字板31上の目盛32に重なるような形状のC字状に形成されている。導光部51は、外縁部にいくにしたがって徐々に肉薄になるように形成されている。   The light guide plate 5 is made of a synthetic resin (translucent material) having translucency, and integrally includes a light guide part 51 and a light receiving part 52 as shown in FIG. The light guide unit 51 is formed in a flat plate shape having a C-shape (horse-shoe shape) in a plan view. The light guide 51 is formed in a C-shape such that the outer edge overlaps the scale 32 on the dial 31. The light guide 51 is formed so as to gradually become thinner toward the outer edge.

The diffusing portion 53 is formed by applying a texture to the back surface 51b, and is a rough surface having many fine irregularities. The diffusion part 53 can be formed, for example, by making the inner surface of a mold for molding the light guide plate 5 into a textured shape. The diffusing portion 53 may be a rough surface having many fine grooves having a V-shaped cross section.

受光部52は、図8に示すように、導光部51の両端部にそれぞれ連なって一対設けられている。受光部52は、導光部51よりも肉厚な板状に形成され、導光部51の文字板31が重ねられる前面51aから導光部51の平面方向と略直交する方向に立設している。   As shown in FIG. 8, a pair of light receiving parts 52 are provided so as to be connected to both ends of the light guide part 51. The light receiving unit 52 is formed in a plate shape thicker than the light guide unit 51, and stands in a direction substantially orthogonal to the planar direction of the light guide unit 51 from the front surface 51 a on which the dial 31 of the light guide unit 51 is superimposed. ing.

導光部51と受光部52が連なる角部分には、反射面54と傾斜面55とが設けられている。反射面54は、前記角部分の外側に設けられ、受光部52の平面方向と導光部51の平面方向の双方に交差するように傾斜している。反射面54は、受光部52内の光を導光部51に向かって反射する。傾斜面55は、前記角部分の内側に設けられ、反射面54と平行な方向に傾斜している。   A reflection surface 54 and an inclined surface 55 are provided at a corner portion where the light guide portion 51 and the light receiving portion 52 are continuous. The reflection surface 54 is provided outside the corner portion, and is inclined so as to intersect both the planar direction of the light receiving unit 52 and the planar direction of the light guide unit 51. The reflection surface 54 reflects the light in the light receiving unit 52 toward the light guide unit 51. The inclined surface 55 is provided inside the corner portion, and is inclined in a direction parallel to the reflecting surface 54.

前述した導光板5は、導光部51の裏面51bが裏カバー10の内面10aと相対する向きで裏カバー10に近づけられ、導光部51が収容凹部13内に収容され、受光部52の一方の表面及び両側面が内壁14に重ねられて、裏カバー10の所定位置に位置付けられた後、内面10aから立設した係止爪(図示せず)に係止して裏カバー10に取り付けられる。すると、導光部51の前面51aが内面10aと面一になり、裏カバー10の内面10aに文字板31を重ねると、裏カバー10と文字板31の間に導光板5が挟まれる格好になり、前面51aが文字板31に重ねられる。   In the light guide plate 5 described above, the back surface 51 b of the light guide unit 51 is brought close to the back cover 10 in a direction facing the inner surface 10 a of the back cover 10, and the light guide unit 51 is housed in the housing recess 13. One surface and both side surfaces are overlapped with the inner wall 14 and positioned at a predetermined position of the back cover 10, and then locked to a locking claw (not shown) standing from the inner surface 10 a and attached to the back cover 10. It is done. Then, the front surface 51a of the light guide 51 is flush with the inner surface 10a, and when the dial plate 31 is overlapped with the inner surface 10a of the back cover 10, the light guide plate 5 is sandwiched between the back cover 10 and the dial plate 31. The front surface 51 a is overlaid on the dial 31.

そして、裏カバー10に表パネル20が取り付けられると、受光部52の先端面52aが、表パネル20に係止した基板33上の文字板用LED36と相対する。文字板用LED36の光は、図4中に一点鎖線で示すように先端面52aから受光部52内に入射した後、反射面54によって導光部51に向かって反射され、導光部51内を進んで拡散部53に到達する。拡散部53に到達した光は、拡散部53によって拡散され、導光部51の前面51aでかつ導光部51の外縁部から文字板31に向かって均一に放射された後、文字板31内を通って文字板31の目盛32から乗員に向かって放射される。こうして、乗員は、文字板用LED36の光によって光輝した目盛32を視認する。   When the front panel 20 is attached to the back cover 10, the front end surface 52 a of the light receiving portion 52 is opposed to the dial LED 36 on the substrate 33 locked to the front panel 20. The light from the dial LED 36 enters the light receiving portion 52 from the front end surface 52 a as shown by a one-dot chain line in FIG. 4, and then is reflected toward the light guiding portion 51 by the reflecting surface 54. To reach the diffusion unit 53. The light that has reached the diffusing portion 53 is diffused by the diffusing portion 53, and is uniformly emitted from the front surface 51 a of the light guide portion 51 and from the outer edge portion of the light guide portion 51 toward the dial plate 31. It radiates from the scale 32 of the dial 31 toward the passenger. Thus, the occupant visually recognizes the scale 32 shined by the light from the dial LED 36.

前述した計器装置1は、さらに、遮光部6と、第2遮光部7と、第3遮光部8とを備えている。遮光部6と第2遮光部7と第3遮光部8とは、例えば黒色の合成樹脂等の遮光性を有した合成樹脂(遮光性材料)で構成されている。   The instrument device 1 described above further includes a light shielding part 6, a second light shielding part 7, and a third light shielding part 8. The light shielding part 6, the second light shielding part 7, and the third light shielding part 8 are made of a synthetic resin (light shielding material) having a light shielding property such as a black synthetic resin.

遮光部6は、図8及び図9に示すように、平板部61と、平板部61に連なる傾斜片62とを備えている。平板部61は、矩形板状に形成され、導光板5の受光部52と略等しい幅でかつ受光部52よりも長く形成されている。傾斜片62は、受光部52と略等しい幅に形成され、平板部61の長手方向(図8中で上下方向)の一端部側の外縁全長から平板部61の平面方向に対して傾斜する方向に立設している。   As shown in FIGS. 8 and 9, the light shielding unit 6 includes a flat plate portion 61 and an inclined piece 62 that is continuous with the flat plate portion 61. The flat plate portion 61 is formed in a rectangular plate shape, has a width substantially equal to the light receiving portion 52 of the light guide plate 5 and is longer than the light receiving portion 52. The inclined piece 62 is formed to have a width substantially equal to that of the light receiving portion 52 and is inclined with respect to the planar direction of the flat plate portion 61 from the entire outer edge on one end side in the longitudinal direction (vertical direction in FIG. 8) of the flat plate portion 61.

前述した遮光部6は、図9に示すように、平板部61が導光板5の受光部52の文字板31と相対する側の表面52bに重ねられ、傾斜片62が傾斜面55に重ねられる。その後、遮光部6は、裏カバー10の内面10aから立設した係止爪(図示せず)に係止して裏カバー10に取り付けられる。そして、裏カバー10に基板33の取り付けられた表パネル20が取り付けられると、平板部61の端面61aが基板33の裏面33bに重ねられて、文字板用LED36の光が直接文字板31の前面31aに向かうことを防止する。   As shown in FIG. 9, in the light shielding unit 6 described above, the flat plate portion 61 is overlaid on the surface 52 b of the light receiving portion 52 of the light guide plate 5 facing the dial 31, and the inclined piece 62 is overlaid on the inclined surface 55. . Thereafter, the light-shielding portion 6 is attached to the back cover 10 by being locked to locking claws (not shown) standing from the inner surface 10 a of the back cover 10. When the front panel 20 to which the substrate 33 is attached is attached to the back cover 10, the end surface 61 a of the flat plate portion 61 is superimposed on the back surface 33 b of the substrate 33, and the light of the dial LED 36 is directly applied to the front surface of the dial 31. It prevents going to 31a.

さらに、傾斜片62の端面62aが文字板31の外周面に重ねられ、受光部52内を通る光が表面52bから文字板31の前面31aに放射されることを防止する。このように、遮光部6は、文字板用LED36及び受光部52と、文字板31との間を仕切って、文字板用LED36及び受光部52から文字板31の前面31aへ向かおうとする光を遮る。   Furthermore, the end surface 62a of the inclined piece 62 is overlapped with the outer peripheral surface of the dial 31 to prevent light passing through the light receiving portion 52 from being emitted from the surface 52b to the front surface 31a of the dial 31. In this way, the light shielding unit 6 divides the dial LED 36 and the light receiving unit 52 and the dial 31 from each other and transmits light from the dial LED 36 and the light receiving unit 52 toward the front surface 31 a of the dial 31. Block.

第2遮光部7は、図4に示すように、基板33に設けられている。第2遮光部7は、基板33の裏面33bから立設した円筒状に形成されている。第2遮光部7は、軸通し孔34を囲むように形成されている。また、第2遮光部7は、軸通し孔34内の出力軸35aと指針用LED37との間の距離よりも大きな内径に形成され、指針用LED37を囲んでいる。   As shown in FIG. 4, the second light shielding part 7 is provided on the substrate 33.

The second light shielding portion 7 is formed so as to surround the through hole 34. The second light-shielding portion 7 is formed with an inner diameter larger than the distance between the output shaft 35 a in the through-hole 34 and the pointer LED 37 and surrounds the pointer LED 37.

第3遮光部8は、図4に示すように、指針4に設けられ、指針袴44と一体に形成されている。第3遮光部8は、指針袴44の上壁45の外縁全周(指針4の基端部4a)から、指針キャップ47から離れる方向に立設した円筒状に形成されている。第3遮光部8は、第2遮光部7の外径よりも大きな内径に形成されている。第3遮光部8は、指針4が基板33上のムーブメント35に取り付けられたときに、先端部が第2遮光部7の先端部と重なるような突出量に形成されている。   As shown in FIG. 4, the third light-shielding portion 8 is provided on the pointer 4 and is formed integrally with the pointer collar 44. The third light-shielding portion 8 is formed in a cylindrical shape erected in a direction away from the pointer cap 47 from the entire outer periphery of the upper wall 45 of the pointer collar 44 (the base end portion 4a of the pointer 4). The third light shielding part 8 is formed with an inner diameter larger than the outer diameter of the second light shielding part 7. The third light-shielding portion 8 is formed with a protruding amount such that the tip portion overlaps the tip portion of the second light-shielding portion 7 when the pointer 4 is attached to the movement 35 on the substrate 33.

前述した第3遮光部8は、指針4が基板33上のムーブメント35に取り付けられると、基板33に向かって立設し、先端部が第2遮光部7の先端部を内側に位置付けて第2遮光部7を囲む。そして、第2遮光部7の開口は、第3遮光部8及び指針袴44の上壁45に覆われる。第2遮光部7及び第3遮光部8は、指針用LED37から文字板31の前面31aへ向かおうとする光を遮る。   When the pointer 4 is attached to the movement 35 on the substrate 33, the third light shielding portion 8 described above is erected toward the substrate 33, and the tip portion is positioned so that the tip portion of the second light shielding portion 7 is located inside. The light shielding part 7 is surrounded. The opening of the second light shielding part 7 is covered with the third light shielding part 8 and the upper wall 45 of the pointer rod 44. The second light-shielding part 7 and the third light-shielding part 8 shield light from the pointer LED 37 toward the front surface 31 a of the dial 31.

前述した構成の計器装置1を組み立てる際には、まず、導光板5を裏カバー10に近づけていき、導光部51を収容凹部13内に位置付けて受光部52を内壁14に重ねて、導光板5を裏カバー10に取り付ける。次いで、遮光部6を受光部52の表面52b及び傾斜面55に重ねて裏カバー10に取り付け、遮光部6と内壁14とで受光部52を囲むようにする。そして、文字板31を、導光部51の前面51a及び裏カバー10の内面10aに重ねて裏カバー10に取り付ける。   When assembling the instrument device 1 having the above-described configuration, first, the light guide plate 5 is brought close to the back cover 10, the light guide portion 51 is positioned in the housing recess 13, and the light receiving portion 52 is overlaid on the inner wall 14. The light plate 5 is attached to the back cover 10. Next, the light shielding unit 6 is attached to the back cover 10 so as to overlap the surface 52 b and the inclined surface 55 of the light receiving unit 52, and the light receiving unit 52 is surrounded by the light shielding unit 6 and the inner wall 14. Then, the dial 31 is attached to the back cover 10 so as to overlap the front surface 51 a of the light guide 51 and the inner surface 10 a of the back cover 10.

また、文字板用LED36や指針用LED37が裏面33bに実装された基板33の前面33aにムーブメント35を取り付け、裏面33b側に突出した出力軸35aに指針4を取り付ける。すると、第3遮光部8が第2遮光部7を囲んで第3遮光部8と指針4の基端部4aが第2遮光部7の開口を覆うとともに、基端部4aが指針用LED37と相対する。次いで、基板33を、指針4を文字板31との間に位置付けるような向きで表パネル20に取り付ける。最後に、表パネル20を裏カバー10に取り付けて、計器装置1が組み立てられる。   Further, the movement 35 is attached to the front surface 33a of the substrate 33 on which the dial LED 36 and the pointer LED 37 are mounted on the back surface 33b, and the pointer 4 is attached to the output shaft 35a protruding to the back surface 33b side. Then, the third light-shielding portion 8 surrounds the second light-shielding portion 7, the third light-shielding portion 8 and the base end portion 4 a of the pointer 4 cover the opening of the second light-shielding portion 7, and the base end portion 4 a is connected to the pointer LED 37. Relative. Next, the substrate 33 is attached to the front panel 20 in such an orientation that the pointer 4 is positioned between the dial 31. Finally, the instrument panel 1 is assembled by attaching the front panel 20 to the back cover 10.

こうして計器装置1が組み立てられると、図4に示すように、文字板用LED36と指針用LED37は、基板33から文字板31に向かって突出し、基板33と文字板31の間の指針4が配されるスペースに位置付けられる。そして、文字板用LED36は、導光板5の受光部52と相対する。文字板用LED36の光は、遮光部6によって文字板31の前面31a側に漏れることなく、受光部52内に入射して反射面54に到達する。その後、反射面54によって導光部51に向かって反射された光は、拡散部53で拡散された後に導光部51から文字板31に向かって均一に放射され、文字板31の目盛32から乗員に向かって放射される。   When the instrument device 1 is assembled in this way, as shown in FIG. 4, the dial LED 36 and the pointer LED 37 protrude from the substrate 33 toward the dial 31, and the pointer 4 between the substrate 33 and the dial 31 is arranged. Positioned in the space to be played. The dial LED 36 faces the light receiving portion 52 of the light guide plate 5. The light from the dial LED 36 enters the light receiving portion 52 and reaches the reflecting surface 54 without leaking to the front surface 31 a side of the dial 31 by the light shielding portion 6. Thereafter, the light reflected by the reflecting surface 54 toward the light guide 51 is diffused by the diffusion unit 53 and then uniformly emitted from the light guide 51 toward the dial 31, and from the scale 32 of the dial 31. Radiated toward the passenger.

また、指針用LED37の光は、第2遮光部7及び第3遮光部8によって文字板31の前面31a側に漏れることなく指針本体41内に入射した後に、露出孔46aから乗員に向かって放射される。こうして、乗員は、文字板用LED36や指針用LED37の光の漏れがなく目盛32のみが均一に光輝した文字板31を視認する。   The light from the LED 37 for the pointer is radiated from the exposure hole 46a toward the occupant after entering the pointer main body 41 without leaking to the front surface 31a side of the dial 31 by the second light shielding portion 7 and the third light shielding portion 8. Is done. In this way, the occupant visually recognizes the dial 31 where the dial LED 36 and the pointer LED 37 are not leaked and only the scale 32 is shining uniformly.

本実施形態によれば、文字板用LED36と導光板5の受光部52が基板33と文字板31の間のスペースに位置付けられるので、計器装置1を小型化(薄型化)できる。さらに、文字板用LED36を文字板31の前面31a側に設けても、遮光部6が文字板用LED36や受光部52から漏れて前面31aへと向かおうとする光を遮るので、前面31aが照らされることがなく、目盛32の視認性を向上させることができる。   According to the present embodiment, the dial LED 36 and the light receiving portion 52 of the light guide plate 5 are positioned in the space between the substrate 33 and the dial 31, so that the instrument device 1 can be downsized (thinned). Furthermore, even if the dial LED 36 is provided on the front surface 31a side of the dial 31, the light shielding portion 6 blocks light that leaks from the dial LED 36 or the light receiving portion 52 and travels toward the front surface 31a. The visibility of the scale 32 can be improved without being illuminated.

また、指針用LED37が基板33と文字板31の間のスペースに位置付けられるので、計器装置1をさらに小型化(薄型化)できる。また、指針用LED37が基板33を挟んでムーブメント35の反対側に設けられているので、基板33上に指針用LED37を実装するスペースを別途確保する必要がなく、計器装置1をさらに小型化できる。さらに、第2遮光部7及び第3遮光部8が指針用LED37から文字板31の前面31aへと向かおうとする光を遮るので、指針4を十分に光輝させることができるだけでなく、前面31aが照らされることがなくなって、目盛32の視認性をさらに向上させることができる。   Moreover, since the pointer LED 37 is positioned in the space between the substrate 33 and the dial 31, the instrument device 1 can be further downsized (thinned). Further, since the pointer LED 37 is provided on the opposite side of the movement 35 with the substrate 33 interposed therebetween, it is not necessary to secure a space for mounting the pointer LED 37 on the substrate 33, and the instrument device 1 can be further downsized. . Furthermore, since the second light-shielding portion 7 and the third light-shielding portion 8 block light from the pointer LED 37 toward the front surface 31a of the dial 31, not only can the pointer 4 be sufficiently brilliant, but also the front surface 31a. Is no longer illuminated, and the visibility of the scale 32 can be further improved.

また、拡散部53が導光部51内の光を拡散させるので、文字板31の目盛32を均一に光輝させることができ、目盛32の視認性をさらに向上させることができる。   Moreover, since the diffusion part 53 diffuses the light in the light guide part 51, the scale 32 of the dial 31 can be uniformly shined, and the visibility of the scale 32 can be further improved.

前述した実施形態においては、計器装置1がスピードメータであったが、タコメータや、スピードメータやタコメータ等を備えた車両用コンビネーションメータ等であってもよい。また、前述した実施形態においては、第3遮光部8が第2遮光部7を囲んでいたが、第2遮光部7が第3遮光部8を囲むようにしてもよい。   In the embodiment described above, the instrument device 1 is a speedometer, but it may be a tachometer, a vehicle combination meter provided with a speedometer, a tachometer, or the like. In the above-described embodiment, the third light shielding unit 8 surrounds the second light shielding unit 7. However, the second light shielding unit 7 may surround the third light shielding unit 8.
