Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a pointer structure of an indicating instrument installed in a vehicle, for example.

[Prior Art] For example, there is a transillumination type indicator instrument installed in an automobile, in particular, a conventional example of a structure in which the pointer of the indicator is displayed in a silhouette, as shown in FIG. 3 and FIG. .
In the figure, 1 is a movement, 2 is a pointer fitted on a pointer shaft 3 expended from the movement 1, and the pointer 2 is a semi-transparent display plate 4 configured in a smoke tone. , A light diffusing plate 6 which receives light from the light source 5 and emits light substantially uniformly over the entire surface, and an opaque pointer 2 is located in front of the light diffusing plate 6 which emits surface light. Since the light source 5 is turned on and the light diffusing plate 6 is surface-emitted and displayed, the position of the pointer 2 is displayed as a silhouette from the outside of the display plate 4. Reference numeral 7 is a light-shielding scale provided on the back surface of the display plate 4.

[Problems to be solved by the invention] However, the conventional guideline 2 with such a silhouette display
In this case, as shown in FIG. 5, since the cross-sectional shape is rectangular, the outline of the pointer 2 shape displayed in silhouette is blurred, and it is difficult to obtain a pointer shape with a clear silhouette. there were.

If this is specifically described based on FIG. 5, when the light of the light diffusion plate 6 is irradiated from the back side of the pointer 2, the silhouette of the pointer generated on the back surface of the display plate 4 is as shown in (c). In the area, the shaded area is shaded by the pointer 2 and is not irradiated with light at all, in the area (b), it is the reflection part of the backlight including the shadow of the pointer 2, and in the area (a), the pointer 2 It is displayed by the reflection part of the backlight only, which does not include the shadow of. Therefore, in the conventional silhouette display, since the silhouette pointer is composed of a dark c region and a relatively light b region around the c region, the silhouette pointer is low in contrast and sharp. There was a problem that it was missing.

[Means for Solving the Problem] The present invention has been made in view of such conventional problems, and an object thereof is to develop a silhouette guideline capable of enhancing the sharpness (contrast). That is, in the description of the conventional example, by eliminating the occurrence of the b region, it is possible to increase the sharpness of the silhouette pointer, but it is virtually impossible to eliminate the b region. In view of this, the present invention proposes a cross-sectional shape of the pointer that can make the b region width as small as possible.

[Embodiment] The present invention will be described in detail below based on the embodiment shown in FIGS. 1 and 2, but in this embodiment, the cross-sectional shape of the pointer is different from that of the conventional example, and other structures are provided. Is the same as the conventional example, the same parts are denoted by the reference numerals quoted in the conventional example, and the description of the structural parts thereof is omitted.

That is, in this embodiment, the pointer 8 is formed to have a V-shaped cross-section, and a V-shaped outer surface is provided with a light-diffusing surface 9 in the shape of, for example, satin for light diffusion. In addition, the seat surface 10 that is not the light diffusion surface is positioned so as to be parallel to the back surface of the display plate 4. Although the pointer has a V-shaped cross section in this embodiment, it is not limited to this and may have, for example, a V shape. However, it is desirable to make the pointer 8 V-shaped in order to reduce the weight.

By making the cross section of the pointer 8 V-shaped as in this embodiment, the reflecting portion (b) including the shadow of the pointer 8 as shown in FIG.
Since the area is sandwiched, the contrast between the silhouette area (c) and the reflection area (a) by the pointer 8 is increased, whereby a high-definition silhouette pointer display is made and the visibility of the silhouette pointer is enhanced. .

[Effects of the Invention] As described above, according to the present invention, the cross-sectional shape of the pointer portion 8 is V-shaped in the pointer structure of the indicating instrument which is illuminated from the rear of the semitransparent display plate 4 to form a shadow on the dial. This is a pointer structure in which the seating surface 10 of the pointer portion 8 faces the display plate 4 in the shape of a triangle or an inverted triangle, so that the blurring region around the silhouette can be narrowed. Therefore, the contrast between the silhouette pointer and the reflected light of the back is increased, so that the silhouette pointer display with a high degree of definition is performed, and by extension, the silhouette pointer display with excellent visibility is achieved.
