（考案が解決しようとする課題） 夜間時に指針600を見やすくするためには、指針600を
充分に光り輝かせる必要があるが、上記自動車用計器で
は、いずれも以下に述べるような問題があった。(Problems to be solved by the invention) In order to make the pointer 600 easy to see at night, it is necessary to make the pointer 600 shine sufficiently, but all of the above-mentioned automobile instruments had the following problems. .

に向かって反射し、他の光は無駄となり、効率が悪かっ
た。このため、指針600を充分に光り輝かせることが出
来ず、夜間時に指針600が見にくい問題があった。That is, in the automotive instrument shown in FIG. 19 to FIG. 21, the amount of light that spreads the distance between the dial plate 200 and the dial plate 400 and reflects the back surface of the dial plate 200 and irradiates the pointer 600. However, if the number of lights is increased, the amount of light applied to the dial plate 400 also increases, and the light applied to the dial plate 400 is reflected, making it rather difficult to see. Further, as shown in FIG. 21, only the light emitted to the slope 602 of the pointer 600 was reflected toward the driver side, the other light wasted, and the efficiency was poor. Therefore, the pointer 600 cannot be made to shine sufficiently and there is a problem that the pointer 600 is difficult to see at night.

ようにしている。The pointer body 60 is made of a transparent synthetic resin such as an acrylic resin, and the fluorescent dye 61 as a phosphor is mixed in a dispersed state. In addition, the pointer body 60 is formed in a rectangular cross section,
The light reflected from the back surface of the dial plate 20 from the lighting bulb 50 is received by the side surface 62 as a light receiving portion, and is reflected by the reflecting portion 64 provided on the one end surface 63 facing the dial 40 side (the lower side of the drawing). I am trying.

より強く集光された状態で光が端面65から外に出る。By doing so, a large amount of light (indirect light) reflected from the back surface of the dial plate 20 from the lighting bulb 50 can be received from the side surface 62 of the pointer main body 60. Then, the received light enters the inside of the pointer main body 60 and causes the fluorescent dye 61 to emit light. At this time, although a part of the incident light is emitted from the side surface 62, the light is totally reflected by the side surface 62 and is repeatedly irradiated to the fluorescent dye 61, and the light emitted from one fluorescent dye 61 is also emitted from the other fluorescent dye 61. As a result, the fluorescent dye 61 emits light almost uniformly throughout the inside of the pointer main body 60. In this case, as shown in FIG. 5 in principle, one end face 63 and the other side while repeating reflection (reflection of a part of light to the outside) and total reflection on the side face 62 inside the pointer main body 60. The other end face (the end face on the driver side where the vehicle instrument is viewed in the upper side of the drawing) 65 of FIG. However, as shown in FIG.
Since the reflecting portion 64 is provided on one end face 63 of the pointer main body 60 of the present invention, all the light is focused on the other end face 65 side. Here, since the width dimension T is set small,
The light emerges from the end face 65 in a more strongly condensed state.

Unlike the embodiment, the other points are the same. That is, the reflecting portion 64 is provided so that the light is reflected by the tip end portion S of the pointer main body 60 toward the driver side (upper side in the drawing). The reflecting portion 64 shown in FIG. 7 is formed by cutting the tip end portion S of the pointer main body 60 so as to incline obliquely upward in the same figure so that the critical angle θ of the transparent synthetic resin forming the pointer main body 60 or more is obtained. Is formed. Further, the reflecting portion 64 shown in FIG. 8 is formed by cutting the tip portion S of the pointer main body 60 so as to be inclined obliquely upward in the drawing, and painting or printing the cut surface, or a reflecting tape. Is formed by pasting. Also,
The reflecting portion 64 shown in FIG. 9 is formed by making the tip end portion S of the pointer main body 60 into a rounded shape (curved shape).

(Refer to the figure) Light reflected from the back side (indirect light)
The light can be received not only on the base end side of, but also on the side surface 62 from the base end to the tip S. Then, in addition to being able to cause the fluorescent dye 61 to emit light almost uniformly inside the pointer main body 60 by the light incident from the side surface 62, as shown in FIG.
Inside the 60, the light is reflected on the side surface 62 and the side surfaces 62 and 65 (reflection of a part of light to the outside) or total reflection, and is condensed on the tip side. In the case of the reflector 64 shown in FIG. 7, the light collected here is totally reflected and is emitted to the outside.
In the case of the reflection part 64 shown in the figure, the light collected here is diffused and emitted to the outside, and in the case of the reflection part 64 shown in FIG. 9, the light collected here is totally reflected or diffusedly reflected. Go outside.
