As described above, it is not necessary to prepare a dedicated light source for each of the hands and the transmissive display panel, and there is an advantage that the illumination design of the hands and the transmissive display panel can be displayed brightly and clearly with a simple structure.

[0003] Such a pointer type meter device is disclosed in, for example, Japanese Unexamined Patent Publication No. Hei 8-189844 and Japanese Unexamined Patent Publication No. Hei 9-1454.
As disclosed in Japanese Patent Application Publication No. 15-154, there is known a so-called edge light illumination type in which a linear light source and a light guide plate are arranged on the back surface of a transmissive display panel. The light guide plate is arranged along the back surface of the transmissive display panel so as to include at least the hands and the display design area, and the light guide plate is arranged on the back surface of the transmissive display plate.

Various meter bodies that are the reference (center) position of the pointer or display design part to be illuminated are arranged as parallel to the linear light source as possible so that the optical path length of the light guide to the illuminated object does not vary in length. In addition, the interior equipment that affects lighting is not disposed between the linear light source and the illumination target, for example, by disposing various display devices as the interior equipment on the opposite side of the linear light source across the meter body. Therefore, there is a problem that a variation in brightness or a lack of brightness occurs in an illumination state, and thus the degree of freedom of layout of the meter main body and the interior device is limited.

A ground color portion is formed.

In the case of this embodiment, the light guides 5 are made of a transparent material such as acrylic resin and are arranged according to the number of the hands 3, and as shown in detail in FIGS. A penetrating hole 51 surrounding the pointer shaft of the main body and extending behind the transmissive display plate 4, and through which the pointer shaft of the meter main body is rotatably inserted;
A light irradiating portion 52 facing the opening portion 41 of the light emitting device, and a flange portion 53 projecting to the outside so as to contact a step portion of the diffusion plate 6 described later.
And a light receiving portion 54 formed at the corner of the rear surface corresponding to the outer peripheral shape of the linear light source 7, and continuously extending from the flange portion 53 to the rear, and the distal end side corresponding to the outer peripheral shape of the linear light source 7. A pair of first holding pieces 55 on which the linear light sources 7 can be placed by rolling, and the rear of the linear light sources 7 which are located substantially in the middle between these holding pieces 55 and extend behind and are mounted on the respective holding pieces 55 A holding portion 57 composed of a second holding piece 56 for preventing falling off, and a center formed on the opposite side of the holding portion 57 and reflecting light of the linear light source 7 taken in from the light receiving portion 54 to the light irradiation portion 52 side.

And a reflection section 59.

The reason for disposing the reflecting portions 58 and 59 on the opposite side of the light receiving portion 54 is that the light irradiating portion 5 close to the light receiving portion 54 is provided.
In the two regions, the light emitted from this region near the linear light source 7 is strong, but the light irradiation unit 52 region far from the light receiving unit 54 is the light irradiation unit 52 region where the light emitted from this region is near the light receiving unit 54. Since the reflection portions 58 and 59 tend to be weaker than the light emitted from the light-receiving portion 54, the light emitted from the region of the light irradiation portion 52 far from the light-receiving portion 54 is enhanced by arranging the reflecting portions 58 and 59 on the opposite side of the light-receiving portion 54. There is an aim.

In the case of the present embodiment, the diffusion plates 6 are made of a semi-transmissive resin material having a light diffusing property, and are arranged on the rear surface corresponding to the number of the transmissive display plates 4.

It is configured such that it can be suspended and held in a state of facing the opening 41 of the first embodiment.

The linear light source 7 is made of CCT, and is held by the holding portion 57 of each light guide 5 and received by the light receiving portion 54 as described above.
Arrangement (array) of each meter body described later in a state facing the
It extends along the direction. For the pointer shafts described later, the vicinity position deviated from the axis thereof, and for each pointer 3, the area corresponding to the rotation center portion 32 is defined as It extends along the arrangement direction.

In the case of this embodiment, as shown in FIG.
The direction of each light guide 5 is different corresponding to the linear light source 7, and the direction of each light guide 5 is different so that the holding portion 57 corresponds to the linear light source 7. This is because the alignment axis of each pointer 3 does not coincide with the extension axis of the linear linear light source 7 and each pointer 3 is slightly shifted with respect to the extension axis of the linear light source 7 as shown in FIG. This is a structure for making the distance between the linear light source 7 and each pointer 3 as equal as possible.

In this embodiment, the structure of all the light guides 5 is the same, but the size of the light guides 5 depends on the arrangement of the hands 3 and the positional relationship with the linear light source 7. May be changed.
