The ground color layer 27 is provided except for the display unit 19. Further, the surface (slope) of the inclined portion 21 is different from the background color (black) of the display portion 19, and the cap 17
A bright silver coloring layer 28 having the same surface color as the above is provided.
The colored layer 28 is opaque.

している。The holding member 12 is made of a white light-shielding synthetic resin, and has a reflecting portion 29 which is formed to be inclined from the light emitting diode 10 side toward the peripheral side of the display plate 9, and the light guide plate 11 or the display plate 9. Is provided with a front surface portion 30. Thus, the holding member 12 holds the light guide plate 11 and the display plate 9 and also serves as a reflecting member.

ものであれば、導光板１１は無くても良い。The light guide plate 11 is made of a light transmissive synthetic resin. The light guide plate 11 is mounted on the front surface portion 30 of the holding member 12 as described above, and the display plate 9 is mounted thereon. Therefore, if the display plate 9 is fixed to the light guide plate 11 by using, for example, an adhesive or a double-sided tape, the display plate 9 will not flutter or deform even if the display plate 9 having a small thickness is used. . In addition, directly from the light emitting diode 10, or the reflecting portion 29 of the holding member 12 and the light guide plate 11,
While repeating reflection with the display plate 9, each light directed to the back surface side of the display plate 9 is diffused by the light guide plate 11,
Uniform display plate illumination is possible. Further, the light guide plate 11 is subjected to a light diffusion process such as graining or a light control process such as halftone dot printing to enable more uniform illumination. The light guide plate 11 may be omitted as long as the display plate 9 has rigidity and the transmitted illumination of the display unit 19 is satisfied.

By disposing the cap 17 so that the back surface side of the peripheral edge of the cap 17 substantially opposes the inclined portion 21, the amount of protrusion of the pointer 8 (cap 17) from the flat surface portion 20 of the display plate 9 is suppressed while the pointer 8 ( The cap 17) can be made to appear to be protruding, which is a novel design. In addition, since the inclined portion 21 of the display plate 9 has a color tone different from that of the plane portion 20 excluding the display portion 19, the center side of the display portion 19 becomes the ring-shaped inclined portion 21, which can provide novelty. Further, according to the present embodiment, the outer diameter of the cap 17 inevitably becomes large, but by matching the color tone of the cap 17 and the color tone of the inclined portion 21, the size of the cap 17 is not particularly emphasized. However, the cap 17 and the inclined portion 21 may have different color tones.

示部７を赤色で発光させる。When the light emitting diode 10 is turned on at night or in dark surroundings, the light from the light emitting diode 10 is emitted directly, or the light guide plate 11, the display plate 9 and the reflection portion 2 are provided.
The light is repeatedly reflected between the light guide plate 9 and the light guide plate 9 toward the back surface side of the light guide plate 11. Then, the light transmitted through the light guide plate 11 illuminates the back surface side of the display plate 9. Then, at daytime, the display unit 19, which was visually recognized as white on a black background, is transparently displayed in red. Further, the light of the light emitting diode 10 illuminates the back surface side of the cap 17 through the hole 22 provided in the display plate 9. Although not shown, a part of the light is reflected by the reflecting surface formed on the base of the indicator 7 and directed toward the tip side of the indicator 7 to cause the indicator 7 to emit red light.

る。The light other than the light directed to the indicator 7 is reflected around the base of the indicator 7 or the back surface of the cap 17 to illuminate the inclined portion 21 of the display plate 9 provided with the silver colored layer 28 with red. (Red light leaks to the inclined portion 21). At this time, the distal end side of the inclined portion 21, that is, the hole portion 22 side is illuminated in dark red, and is gradually illuminated in pale red as it approaches the plane portion 20. In this way, since the periphery of the cap 17 that is visually recognized as dark (black) is illuminated in a ring shape with different brightness and tint, the cap 17 feels more floating. In other words, the pointer-type instrument has a sense of depth, and a novel appearance different from that during daytime can be realized.

ることができる。It should be noted that the end portion 24 of the cap 17 is the flat portion 2
If it is located in front of 0 (on the side of the see-through plate 16), light leakage is caused
There is a possibility that the number display portion 19B close to the inclined portion 21 is adversely affected by illuminating up to 0. On the contrary, the end portion 24 has the flat surface portion 2
When it becomes lower than 0 and approaches the inclined portion 21 side too much, the gap between the end portion 24 of the cap 17 and the inclined portion 21 becomes small, and light (light leakage) illuminated (visible) around the cap 17 is generated. There are few and it is hard to give a sense of depth. Therefore, the outer diameter D of the cap 17 is smaller than the diameter D1 of the intersecting portion 23 of the display plate 9, and the end of the inclined portion 21 (that is, the hole portion 2).
2) The end 24 of the cap 17 and the inclined portion 21 are larger when the end 24 on the inclined portion 21 side of the peripheral edge of the cap 17 and the height of the flat portion 20 of the display plate 9 are substantially the same. It is a proper gap, there is no light leakage to the flat surface portion 20, and a sense of depth is easily obtained. Further, the color tone of the inclined portion 21 is not limited to silver, and may be any color as long as it is different from the color tone of the flat portion 20. However, the light-colored system can make the light (light leakage) illuminated on the inclined portion 21 clearer to give a more novel and sense of depth.

The light of 0 A is transmitted through the transmissive portion 33 provided with the blue transmissive coloring layer 35 of the display plate 9 toward the back surface side of the cap 17,
The inclined portion 21 of the display plate 9 provided with the silver colored layer 28 is illuminated with blue light by reflecting on the periphery of the base of the indicator 7 or the back surface of the cap 17 (blue light leaks to the inclined portion 21). At this time, the end of the inclined portion 21, that is, the hole 2
The second side is dark blue, and is gradually illuminated in pale blue as it approaches the convex portion 31. Therefore, as in the first embodiment, the pointer-type instrument has a sense of depth, and a novel appearance different from that during daytime can be realized.

い。The end 24 of the cap 17 has a convex portion 31.
When located in front of the top portion 34 (on the side of the see-through plate 16), the leaked light illuminates the flat surface portion 20 and is close to the inclined portion 21.
9B may be adversely affected. On the other hand, when the end 24 is below the top 34 and too close to the inclined portion 21 (slope) side, the gap between the end 24 of the cap 17 and the inclined portion 21 becomes small and the periphery of the cap 17 is illuminated. There is little light (light leakage) emitted (visible), and it is difficult to give a sense of depth. Therefore, the outer diameter D of the cap 17 is smaller than the diameter D2 of the top portion 34 of the convex portion 31, larger than the end of the inclined portion 21, and the end portion 24 of the peripheral edge of the cap 17 on the inclined portion 21 side and the top portion 34 of the convex portion 31. When the heights are substantially the same, the gap between the end portion 24 of the cap 17 and the inclined portion 21 is appropriate, there is no light leakage to the flat surface portion 20, and a sense of depth is easily obtained.
