Description

The present invention relates to a dial and a timepiece.

2. Description of the Related Art Conventionally, electronic devices such as a timepiece having a solar panel that receives light to generate power have been widely known (for example, see Patent Document 1). Such an electronic device can be used for a long period of time without replacing the battery by generating power from the solar panel and charging the secondary battery with the generated power.

In the case of an electronic device including a solar panel, the solar panel is arranged under a light-transmitting dial plate (back surface side) so that light can be received, as described in Patent Document 1, for example. It

JP, 2014-173921, A

However, the surface of the solar panel is dark purple, and if you place it under the light-transmitting dial (back side), the ground color of the solar panel will be transparent from the visible side of the electronic device. It will be visible and the design of the dial will deteriorate.

In this respect, the light transmission of the dial plate is reduced to make the background color of the solar panel difficult to see through, and a reflective polarizing plate is provided between the dial plate and the solar panel to make the background color of the solar panel external. Although it may be difficult to visually recognize it, it is difficult to completely see the ground color of the solar panel depending on the viewing angle even if the above configuration is adopted.

Has been done. Along with this, since the power consumption is also increasing, there is a demand for avoiding the decrease in power generation efficiency by the solar panel as much as possible.
If the light transmission of the dial is reduced or a reflective polarizing plate is provided, the amount of light received by the solar panel will be reduced by that amount and the power generation efficiency will be reduced, but to improve the design of the dial. It is not desirable to sacrifice the power generation efficiency of solar panels.

Also, in electronic devices such as watches, where the case that houses the dial, solar panel, etc. is required to be downsized, if a reflective polarizing plate, etc. is provided between the dial and solar panel, the thickness will increase accordingly. However, there is also a problem that it goes against the demand for miniaturization.

The present invention has been made in view of the above circumstances, and provides a dial and a watch with excellent design in which the ground color of the solar panel is not visually recognized from the outside without sacrificing the power generation efficiency of the solar panel. The purpose is to do.

In order to solve the above problems, the dial according to the present invention,

The dial 4 has an uneven surface 4a on one side and a flat surface 4b on the other side, and includes a transparent or semitransparent plate-shaped base material 41.
The base material 41 is formed of, for example, a transparent or translucent resin or glass. The material forming the base material 41 is not particularly limited.
In this embodiment, as shown in FIG. 2, the surface of the base material 41 on the viewing side is the uneven surface 4a, and the surface of the back surface of the base material 41 (that is, the side opposite to the viewing side) is a flat surface. It is 4b.
The flat surface 4b is not limited to a perfect flat surface (smooth surface), and includes a surface that has no irregularities and is substantially smoothed.

As shown in FIGS. 1 and 2, the concave-convex surface 4a is composed of a plurality of concentric circular protrusions having a sawtooth shape in cross section and a V-shaped concave portion located between adjacent convex portions. Become.
The concave-convex surface 4a functions as a reflecting surface for reflecting light by a plurality of inclined surfaces formed by a convex portion and a concave portion, complexly refracts light like a prism, and diffusely reflects it.
The shape of the uneven surface 4a is not limited to the one illustrated here, and may be, for example, a spiral shape instead of the concentric shape, or may be formed radially from the center of the dial 4 toward the outer circumference. It may be constituted by a plurality of groove portions formed.

On the uneven surface 4a of the base material 41, the first vapor deposition layer 42 having no peak of the spectral reflectance in the visible light region is formed.
FIG. 3 is a graph showing the spectral reflectance of the first vapor deposition layer 42 in this embodiment.
In FIG. 3, the solid line indicates the spectral reflectance of the first vapor deposition layer 42 when the incident angle is 0 degrees, and the broken line indicates the spectral reflectance of the first vapor deposition layer 42 when the incident angle is 45 degrees.
As shown in FIG. 3, regardless of whether the incident angle is 0 degree or the incident angle is 45 degrees, the spectral reflectance of the first vapor deposition layer 42 is moderate at about 20% regardless of the wavelength of light. It has changed and does not have a peak of spectral reflectance for a specific wavelength in the visible light region.
As described above, the first vapor deposition layer 42 is a reflection film or a high-brightness transmissive film that does not have a specific color, and when the first vapor deposition layer 42 is viewed from the outside, it has a silver or tint close to it. Visible as a film.

On the other hand, on the flat surface 4b of the base material 41, the second vapor deposition layer 43 having the peak of the spectral reflectance in the visible light region is formed.
FIG. 4 is a graph showing the spectral reflectance of the second vapor deposition layer 43 in this embodiment.
In FIG. 4, the solid line indicates the spectral reflectance of the second vapor deposition layer 43 when the incident angle is 0 degrees, and the broken line indicates the spectral reflectance of the second vapor deposition layer 43 when the incident angle is 45 degrees.
As shown in FIG. 4, regardless of whether the incident angle is 0 degree or the incident angle is 45 degrees, the second vapor deposition layer 43 has a peak spectral reflectance at a wavelength of about 450 nm. In the vapor-deposited layer 43, particularly, a large amount of blue wavelength component is reflected. Therefore, the second vapor deposition layer 43 is visually recognized as a film having a blue color or a hue close to that when viewed from the outside.
In particular, as in this embodiment, by providing the second vapor deposition layer 43 on a flat surface, it is possible to develop a desired color.

In the present embodiment, the first vapor-deposited layer 42 and the second vapor-deposited layer 43 are respectively composed of “oxide” represented by TiO2, SiO2, ZrO2, etc., “fluoride” represented by MgF2, CaF2, etc., ZnS. It is composed by laminating three kinds of compounds of "sulfide" represented by. In addition to these compounds, pure metals such as Ti and Cr may be combined in some cases.
The film forming material (vapor deposition material) for forming the first vapor deposition layer 42 and the second vapor deposition layer 43 is not particularly limited, and any film component generally used for optical vapor deposition or the like can be appropriately applied.
Further, the first vapor deposition layer 42 and the second vapor deposition layer 43 are formed by stacking, for example, several to 20 layers of film.
Note that the film configurations of the first vapor deposition layer 42 and the second vapor deposition layer 43 are not limited to those exemplified here, and may be composed of one layer, or may be composed of 100 or more laminated layers. Good.
When the first vapor-deposited layer 42 and the second vapor-deposited layer 43 are composed of multiple layers, for example, two to three kinds of the film-forming substances (vapor-depositing materials) as exemplified above are used, and these are alternated. You may form a multilayer film by stacking on.
Moreover, the film thickness of the 1st vapor deposition layer 42 and the 2nd vapor deposition layer 43 is several nm-several hundred nm (several tens Å-several thousands Å), for example.
When the first vapor deposition layer 42 and the second vapor deposition layer 43 are multilayer films, the total thickness of the vapor deposition layers 42 and 43 is preferably 1 μm or less.

In the present embodiment, the uneven surface 4a and the flat surface 4b are formed on the front and back surfaces of the base material 41 as described above, and the first vapor deposition layer 42 is formed on the uneven surface 4a and the second vapor deposition is formed on the flat surface 4b. Since the layer 43 is formed, the first vapor deposition layer 42 and the second vapor deposition layer 43 are arranged so as to overlap each other.
Since the first vapor deposition layer 42 is formed on the uneven surface 4a formed on the front surface side of the base material 41, the first vapor deposition layer 42 is arranged closer to the viewing side than the second vapor deposition layer 43.
Further, in the present embodiment, as described above, the dial plate 4 in which the first vapor deposition layer 42 is formed on the uneven surface 4a and the second vapor deposition layer 43 is formed on the flat surface 4b is inside the watch case 1. The solar panel 5 housed in is arranged on the viewing side.

Next, the operation of the dial 4 in this embodiment and the timepiece 100 to which the dial 4 is applied will be described.

In the present embodiment, first, unevenness is formed on one surface of the transparent or semitransparent plate-shaped base material 41 to form an uneven surface 4a, and the other surface of the base material 41 is a flat surface 4b having no unevenness. Then, the first vapor deposition layer 42 having no peak of the spectral reflectance in the visible light region is formed on the uneven surface 4a by vapor deposition, and the second vapor deposition having the peak of the spectral reflectance in the visible light region is formed on the flat surface 4b. Layer 43 is deposited. As a result, the dial 4 is formed.
In this way, by forming the first vapor deposition layer 42 on one surface of the base material 41 and forming the second vapor deposition layer 43 on the other surface of the base material 41, the base material 41 of the dial 4 can be formed. The first vapor deposition layer 42 and the second vapor deposition layer 43 are arranged on the front and back so as to overlap each other.

The dial plate 4 is housed in the watch case 1 with the uneven surface 4a having the first vapor deposition layer 42 as the viewing side and the flat surface 4b having the second vapor deposition layer 43 as the back surface. To do.
Further, the solar panel 5 is housed in the watch case 1 so as to be arranged on the back surface side of the dial 4 (the back surface side opposite to the viewing side in the timepiece 100).
Further, a timepiece movement or the like is further accommodated in the timepiece case 1, the windshield member 11 is fitted into the opening portion on the viewing side of the timepiece case 1, and the back cover is attached to the opening portion on the back surface side of the timepiece case 1.
This completes the timepiece 100.

In this way, the uneven surface 4a is formed on one surface of the dial 4, and the first vapor deposition layer 42 which is a high-brightness transmission film having no peak of the spectral reflectance in the visible light region is formed on the uneven surface 4a. Then, the complex refraction/reflection of light due to the unevenness of the uneven surface 4 a and the reflection of light due to the first vapor deposition layer 42 are combined, and the light is diffusely reflected intricately, and the light is below the first vapor deposition layer 42. Make things hard to see. Further, since the light is diffusely reflected, it is possible to obtain an excellent visual effect as when the light is reflected by the prism.
Further, a flat surface 4b is formed on the other surface of the dial plate 4, and a second vapor deposition layer 43 having a peak of spectral reflectance in the visible light region is formed on the flat surface 4b. While making certain things more difficult to see, the color of the specific wavelength reflected by the second vapor deposition layer 43 (in the present embodiment, blue or a color close to this as shown in FIG. 4) is the dial 4 Can be seen through the surface (that is, the surface on the viewing side) and is visually recognized as the colored dial plate 4 having a glossy feeling.
By arranging such a dial 4 on the viewing side with respect to the solar panel 5, the solar panel 5, which is a ground color such as dark purple, is placed below the light-transmitting dial 4 (on the back side). Even in such a case, the ground color of the solar panel 5 is transparent to the viewer and cannot be seen, and the timepiece 100 having excellent design can be provided.
Further, even when the dial 4 on which the first vapor deposition layer 42 and the second vapor deposition layer 43 are formed is arranged closer to the viewing side than the solar panel 5, the first vapor deposition layer 42 and the second vapor deposition layer are arranged. As described above, the layer 43 has a very thin film thickness of, for example, about several nm to several hundreds nm, and thus does not prevent the solar panel 5 from receiving light, so that the power generation efficiency of the solar panel 5 does not decrease.

As described above, according to the present embodiment, the dial plate 4 is formed on the uneven surface 4a, and is formed on the first vapor deposition layer 42 having no peak of the spectral reflectance in the visible light region and the flat surface 4b. And the second vapor deposition layer 43 having a peak of the spectral reflectance in the visible light region, and the first vapor deposition layer 42 and the second vapor deposition layer 43 are arranged so as to overlap with each other.
As a result, the complex refraction/reflection of light due to the unevenness of the uneven surface 4a and the reflection of the light due to the first vapor deposition layer 42 are combined to diffusely reflect the light, resulting in a glossy and excellent visual effect. It is possible to realize the dial 4 having the.
Further, as described above, the unevenness of the uneven surface 4a and the first vapor deposition layer 42 make it difficult to visually recognize the object under the dial 4 by reflecting light in a complicated manner.
Further, a flat surface 4b is formed on the other surface of the dial plate 4, and a second vapor deposition layer 43 having a peak of spectral reflectance in the visible light region is formed on the flat surface 4b. While making certain things more difficult to see, the color of the specific wavelength reflected by the second vapor deposition layer 43 (in the present embodiment, blue or a color close to this as shown in FIG. 4) is the dial 4 Since it can be seen through the surface (that is, the surface on the viewing side) of the sheet and is visually recognized as the colored dial plate 4 having a glossy feeling, it is possible to realize the dial plate 4 excellent in design.
In addition, in the present embodiment, the dial 4 includes a transparent or semitransparent plate-like base material 41, and the uneven surface 4a and the flat surface 4b are formed on the front and back surfaces of the base material 41, and the uneven surface 4a and the flat surface are formed. A first vapor deposition layer 42 and a second vapor deposition layer 43 are formed on 4b.
Therefore, the number of components can be reduced and the dial plate 4 can be made thin as compared with the case where a sheet or the like for vapor-depositing the first vapor deposition layer 42 and the second vapor deposition layer 43 is separately provided.
Further, in the present embodiment, the first vapor deposition layer 42 arranged on the uneven surface 4a is arranged on the viewing side with respect to the second vapor deposition layer 43 arranged on the flat surface 4b. Therefore, when the dial 4 is viewed from the viewing side, the surface of the dial 4 is metallic due to complicated refraction/reflection of light due to the unevenness of the uneven surface 4a and light reflection due to the first vapor deposition layer 42. It has a beautiful luster and a beautiful appearance.
Further, in the present embodiment, since the dial 4 is arranged on the viewing side of the solar panel 5, it is effective that the ground color of the solar panel 5 is transparent and visible on the viewing side of the dial 4. Can be prevented. In addition, while preventing the solar panel 5 from being transparent as described above, the dial plate 4 itself is a transparent or semi-transparent base material 41 provided with thin films on the front and back thereof, so that the light transmittance is secured. The light reception of the solar panel 5 is not hindered. Therefore, the power generation efficiency does not decrease, and even the timepiece (electronic device) 100 in which a large number of high-performance parts such as various antenna devices and sensors are mounted can cover the power consumption by the power generation by the solar panel 5. It is possible to achieve both high designability and high functionality/multifunctionality of the timepiece (electronic device) 100.

Although the embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the embodiments and various modifications can be made without departing from the scope of the invention.

For example, in the present embodiment, the case where the second vapor deposition layer 43 formed on the flat surface 4b reflects a large amount of blue or wavelengths in the vicinity thereof is exemplified, but the second vapor deposition layer 43 does not emit visible light. The peak of the spectral reflectance in the region is not limited to that having a blue wavelength or a wavelength in the vicinity thereof.
For example, as shown in FIG. 5A, the second vapor deposition layer 43 may be a layer in which the spectral reflectance has a peak at a wavelength of around 500 nm and a large amount of green wavelength component is reflected.
Further, as shown in FIG. 5B, the spectral reflectance may have a peak at a wavelength of around 600 nm and a large amount of yellow wavelength components may be reflected.
Further, as shown in FIG. 5C, the spectral reflectance may show a peak at wavelengths around 450 nm and wavelengths around 600 nm, and a large amount of pink wavelength components may be reflected.
Further, as shown in FIG. 5D, the spectral reflectance may have a peak at a wavelength of around 700 nm and a large amount of red wavelength component may be reflected.
Further, as shown in FIG. 5E, the spectral reflectance may have a peak at a wavelength of about 450 nm to about 600 nm, and a large amount of champagne-colored wavelength component may be reflected.
As described above, by adopting the second vapor deposition layer 43 having the spectral reflectance peak in various visible light regions, it is possible to realize the dial plates 4 of various colors.

Further, in the present embodiment, the concave-convex surface 4a has a saw-toothed shape in cross section, but the concave-convex shape on the concave-convex surface 4a is not limited to this.
For example, as shown in FIG. 6, a concavo-convex surface 6a having no serrated peak may be provided on the viewing side of the base material 61 of the dial plate 6.
Also in this case, the flat surface 6b is formed on the back surface side of the base material 61, the first vapor deposition layer 62 is formed on the uneven surface 6a, and the second vapor deposition layer 63 is formed on the flat surface 6b.

Alternatively, the first vapor deposition layer 72 may be formed on the flat surface 7b, and the second vapor deposition layer 73 may be formed on the flat surface 7b.
In this case as well, the visual effect of superimposing the first vapor deposition layer 72 and the second vapor deposition layer 73 and the effect of making it difficult to visually recognize what is under the dial 7 can be expected.

Further, in the present embodiment, the case where the first vapor deposition layer 42 and the second vapor deposition layer 43 are provided on the front and back of the base material 41 of the dial 4 has been exemplified, but the configuration of the dial is not limited to this.
For example, as shown in FIG. 8, a concavo-convex surface 8a is formed on one surface of a base material 81 constituting the dial 8, and the first vapor deposition layer 82 is formed on the concavo-convex surface 8a, and the base material is formed. The front surface side of the solar panel 5 arranged below 81 (back surface side) may be the flat surface 5b, and the second vapor deposition layer 83 may be formed on the flat surface 5b.
Also in this case, it is possible to expect a visual effect by overlapping the first vapor deposition layer 82 and the second vapor deposition layer 83 and an effect of making it difficult to visually recognize what is under the dial 8.
In this case, the uneven surface 8a and the first vapor deposition layer 82 formed thereon may be arranged on the back surface side of the base material 81.

Furthermore, the dial 4 is not limited to the case where the dial 4 is composed of the base material 41, the first vapor deposition layer 42, and the second vapor deposition layer 43.
For example, as shown in FIG. 9, in addition to the base material 91, the dial 9 may include a sheet member 94 arranged below the base material 91 (on the back surface side). In this case, the uneven surface 9a is formed on one surface of the base material 91, the first vapor deposition layer 92 is formed on the uneven surface 9a, and one surface of the sheet member 94 is formed as the flat surface 9b.

Further, the flat surface 9b and the second vapor deposition layer 93 formed thereon may be arranged on the visible side (front surface side) of the sheet member 94.

Further, in the present embodiment, the case where the display unit 3 including the dial 4 is the analog type including the pointer 31 is illustrated, but the display unit 3 including the dial 4 is not limited to the analog type and the liquid crystal panel is used. The dial plate may be a combination of analog type and digital type.

Further, although the case where the dial 4 is provided on the timepiece 100 is illustrated in the present embodiment, the electronic device provided with the dial 4 is not limited to the timepiece.
