Abstract

PROBLEM TO BE SOLVED: To facilitate miniaturization, make a degree of freedom of design high and enable manufacture at a low cost by providing a high reflectance layer on the side of the visually observing person of the center part of a pointer rotation part. SOLUTION: A main part composed of a pointer rotation center part 2 and a pointer part 3 is formed of a transparent member, and light illuminating the pointer rotation center part 2 is introduced to the pointer part 3 by an illumination means of an electric lamp, an emission diode and the like. Thereby improvement of visibility is contrived. A high reflectance layer 4 having the surface of a silver color brilliant face is provided, and light leakage for a visible person side is prevented to enhance visibility of the pointer part 3. F or instance, a black coloring layer 5 is disposed on the face of the visually observing person of the high reflectance layer 4. Thereby light irradiating the pointer rotation center part 2 can be efficiently supplied to the pointer part, and a degree of freedom of coloring and display can be improved. Thus, miniaturization is made possible, a degree of freedom is high and manufacture at a low cost is enabled.

2. Description of the Related Art Light guide illumination type instrument panel pointers are excellent in visibility at night and in dark places, and are therefore widely used in fields requiring particularly high visibility, such as speedometers of automobiles. Here, a cross section of a general light guide illumination type instrument panel pointer is schematically shown in FIG. Reference numeral 1 in the figure denotes a shaft connected to the pointer driving unit. The main part consisting of the pointer rotation center part 2 and the pointer part 3 is made of a transparent material, and the pointer rotation center part 2 is irradiated with light by a lighting means such as a light bulb or a light emitting diode, and the light is guided to the pointer part 3. And contributes to the improvement of visibility. Here, in order to prevent light from leaking to the viewer side and to further enhance the visibility of the pointer portion 3, a light-shielding cap α is fixed to the pointer rotation center portion 2.

The instrument panel pointer requires a light-shielding cap α, so that the number of parts is increased, and a process for attaching the cap is required. In addition, the light transmission to the pointer 3 was not good, which required illumination equipment with a large light amount, which resulted in an increase in the size and weight of the entire meter and increased power consumption.

On the other hand, an instrument panel pointer as shown in FIG. 3 is obtained by two-color molding. This is a method in which, for example, a light shielding cap β is prepared in advance, and the main part including the pointer rotation center portion 2 and the pointer portion 3 is molded by using this as an insert. In this case, there is an advantage that automation is possible by adopting a method of molding while rotating the mold, but equipment costs, mold costs, and the like are increased. Further, if the color of the cap β is made darker for the purpose of improving the design, the light absorption on the back surface of the cap β becomes large, and lighting equipment with a large amount of light is required like the instrument panel pointer shown in FIG.
Increasing the size, increasing the weight, and increasing power consumption have become problems.
In addition, in the instrument panel pointers shown in FIGS. 2 and 3, the size of the light-shielding cap portion is increased to restrict the design, and because the weight is increased, the driving portion of the meter is inevitably increased in size.

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a high-reflectance layer refers to a layer having a high light reflectance, such as a light-colored layer such as white, white silver, or light gray. Further, the surface may be a layer having a metallic luster. The light applied to the center of rotation of the pointer is efficiently guided to the pointer by the high reflectivity layer, thereby contributing to improvement in visibility. Since the high reflectivity layer is a thin layer, it is lightweight and does not substantially increase the load on the meter driving unit. Furthermore, by arranging a colored layer having various patterns, characters, designs, and the like having different colors from the high-reflectance layer on the viewer's side surface of the high-reflectivity layer over the entire surface or a part thereof, the degree of freedom in color arrangement and display is improved. Can be improved.

Such a high-reflectance layer or colored layer is formed, for example, by in-mold (in-mold hot stamping).
Thus, the configuration can be made more easily and with good productivity. In this method, a long hot stamp film (transfer foil) is inserted into the mold during injection molding, and positioning is performed.
This is a method of performing injection molding and performing hot stamping at the same time as molding. By applying this method, a high-reflectance layer can be formed by inserting a hot stamp film having a high-reflectance layer inside the viewer's side of the pointer rotation center of the pointer-forming mold during molding. .

At this time, if the hot stamp film has a colored layer on the viewer side of the high reflectivity layer, the high reflectivity layer and the colored layer can be simultaneously formed. In this way, the in-mold facilitates downsizing and weight reduction especially at the center of rotation of the pointer. Further, assemblability is improved, and a light-shielding cap, which is required as a substantially separate part in the prior art, becomes unnecessary. Furthermore, as an effect unique to the in-mold method, regardless of the shape of the center of rotation of the pointer of the instrument panel due to the deformation of the transfer printing film used at the time of molding, even a complicated shape such as a cubic curved surface can be in close contact with the surface. A reflectance layer and a colored layer can be formed, and the emitted light can be used effectively, and
The degree of freedom in design can be extremely high. In addition, as an application of the above technology, a light emitting surface can be provided on a pointer or a translucent layer can be provided to further improve the visibility.
