Further, a slit 27c is formed in the second base 27a.
And penetrates the light guide linking portion 25c of the first needle 25. Further, the second needle 27 has a variable light linking part 27d protruding from the second base 27a. The variable light linking portion 27d is formed in a curved shape, and has a shape offset to the outside with respect to the light guiding linking portion 25c of the first needle 25,
The dial 1 extends into the center hole 1a of the dial 1. The first needle 2
5 and the second hand 27 are connected to the pointer shaft 2 of the rotation drive unit 19.
9. The rotation drive section 19 is configured to rotationally drive the pointer shaft 29 according to a vehicle speed signal.

The light guide member 21 includes the rotation drive unit 19.
Is fixed to the housing 19a. This light guide member 2
1 is a general part 21a, a variable light guide part 21b, and an introduction light part 21c.
It consists of Details of the light guide member 21 will be described later. The light guide linking portion 25c of the first needle 25 is connected to the light guide member 21.
And the variable light linking portion 27d of the second needle 27 is connected to the variable light guiding portion 21b of the light guiding member 21.
Is facing.

The lamp 23 is opposed to the introduction light section 21c. The lamp 23 is connected to a light switch 31 and an ignition switch 33. A cap 35 covers the first base 25a and the second base 27a of the first needle 25 and the second needle 27.

FIG. 4 is a plan view of the light guide member 21.
(A). As shown in this figure, the general portion 21a of the light guide member 21 has a substantially circular shape. Variable light guide 21b
Is provided in a predetermined range outside the general part. This predetermined range is provided corresponding to the specific instruction state of the pointer 17 (see FIG. 2). That is, the variable light guide portion 21b is provided outside the circular general portion 21a within the range of the angle α, and has the same radial width in the range of the angle α. The range of the angle α corresponds to, for example, 100 to 180 km / h as the specific instruction state of the pointer 17.

Although the second needle 27 in FIG. 1 and the variable light guide 21b in FIG. 4A are hatched, the material of the second needle 27 is the first needle 25 in this embodiment. The variable light guide section 21b is made of the same material as the general section 21a.

Next, the operation will be described.

First, when the vehicle starts running due to the operation of the ignition switch 33, the rotation drive unit 19 causes the rotation of the pointer shaft 2 according to the vehicle speed signal according to the vehicle speed signal at the time of running.
Rotate 9 The rotation of the pointer shaft 29 causes the first hand 25 and the second hand 27 to rotate integrally, and indicates the vehicle speed as the hand 17 (mainly the first hand 25). In this case, if the light switch 31 is not operated, the lamp 23
Does not light, and the pointer 17 does not emit any light, and gives a normal vehicle speed instruction.

When the light switch 31 is operated at night or the like, the lamp 23 is turned on, and light is guided to the hands 17.
That is, the light of the lamp 23 is transmitted from the introduction light portion 21c to the variable light
1b and the general section 21a. Light is guided from the general portion 21a to the first needle 25 via the light guide linking portion 25c. In this case, the light guide linking portion 25c of the first needle 25 is
1 always faces the general part 21a,
Is always guided to the first hand 25, and the first hand 25 can always indicate the vehicle speed while emitting light.

Next, the second needle 27 is moved to the variable light linking section 27d.
23 only when it is facing the variable light guide 21b.
Is guided from the variable light guide section 21b to the second needle 27 via the variable light linking section 27d. Therefore, the second needle 27 emits light only in the range of the angle α in FIG. This range corresponds to the specific instruction state of the pointer 17, in this embodiment, 100 to 180 km / h, and when the vehicle speed becomes 100 km / h or more, the second hand 2
7 will also emit light. Therefore, the vehicle speed is 100 km /
When the vehicle speed is less than 100 km / h, only the first hand 25 emits light to give a normal vehicle speed instruction. When the vehicle speed becomes 100 km / h or more, the second hand 27 also emits light to notify that the vehicle speed exceeds 100 km / h. Let them know. Therefore, the vehicle speed is 100 km
At the time of / h, the visual recognition state of the pointer 17 changes, and it is possible to clearly notify the occupant that the vehicle speed is high. In this case, when the second hand 27 also emits light, the thickness of the pointer 17 becomes thicker than when only the first hand 25 emits light, so that the visual recognition state can be changed more clearly. Further, since such a change in the visual recognition state is realized by overlapping the first needle 25 and the second needle 27, the change in the visual recognition state can be greatly added, and the change can be recognized more clearly. can do.

In the first embodiment, the visual recognition state is changed by changing the thickness of the pointer 17.
The viewing state can be changed by changing the brightness or color of the image. For example, the pointer can be changed to red or yellow when the vehicle speed falls within a specific range by coloring the variable light guide portion 21b with red or yellow, or attaching a red or yellow film. In this case, the visibility can be changed more clearly, and the user can more easily notice. The setting of the angle α is free, and the setting of the angle α allows the specific instruction state of the pointer 17 to be freely changed.

Further, the light guide member 21 is formed as shown in FIG.
It can also be formed as shown in FIG. In the example shown in FIG. 4B, the variable light guide 21b gradually disappears. According to this example, when the variable light linking portion 27d of the second hand 27 approaches the variable light guiding portion 21b, the variable light linking portion 27d completely overlaps the variable light guiding portion 21b and the second needle 27 When the pointer 17 is further rotated, the variable light linking unit 27d is turned on by the variable light guiding unit 2.
1b gradually disappears from the variable light guide portion 21b on the annihilation side, and the amount of light guided to the second hand 27 gradually decreases.
7 can be changed. Therefore, for example, immediately after the vehicle speed exceeds 100 km / h, the second hand 27 is also made to emit light brightly, and the driver is clearly instructed. After that, when the vehicle speed further increases, the light emission state of the second hand 27 is changed. It can be changed gradually, and the change in vehicle speed can be notified more clearly.

The example of FIG. 4C is basically the same as the shape of FIG. 4A, but in this example, the notch 21
The variable light guide part 21b is left by providing d. Therefore, in the example of (c), substantially the same operation and effect as in (a) can be obtained.

That is, a film having a deep hue such as red is attached to the variable light guide portion 21b. The color of the general portion 21a is, for example, yellow. The material of the variable light guide 21b may be red or the like.

In this embodiment, by turning on the lamp 23, light can be guided from the general portion 21a to the pointer 17 via the light guide linking portion 17b, and the variable light linking portion 17c can be guided.
Faces the variable light guide section 21b, and thereby the variable light guide section 21
Light can also be guided from b to the pointer 17. Therefore, for example, when the instruction is performed at less than 100 km / h, the pointer 17 emits yellow light, and when the specific instruction state exceeds 100 km / h, red can be added to change the color of the pointer 17. Therefore, it is possible to clearly indicate that the vehicle speed has become, for example, 100 km / h or more by changing the color of the pointer 17.

Thus, this embodiment can provide substantially the same functions and effects as those of the first embodiment. In addition, in this embodiment, the pointer 17 is constituted by one needle, and the structure is simple. Further, various colors can be set by changing the film of the variable light guide 21b. By changing the transmittance of the variable light guide section 21 with respect to the general section 21a, a change in luminance can be given when the pointer 17 is in the specific instruction state.
