For example, the band attachment portion 12 of the watch case 1, the side surface (outer peripheral surface) of the watch case 1, and the like may be provided with a configuration described later as the exterior member 5. FIG.

Here, a specific configuration of the exterior member 5 in this embodiment will be described with reference to FIG. 2(a). In the following description, the term "exterior member 5" includes both the bezel member 2 and the dial 3 in this embodiment.
FIG. 2(a) is a cross-sectional view of the main part of the exterior member. In FIG. 2(a), when the exterior member 5 is mounted on the timepiece 100, the visible side (front side of the timepiece 100) is shown facing up.
The exterior member 5 includes a colored layer 52 , a first transparent layer 53 and a decorative member 54 . Moreover, in this embodiment, the exterior member 5 includes the base material 51 and the second transparent layer 55 .

In the exterior member 5 of the present embodiment, the colored layer 52, the first transparent layer 53, the decorative member 54, and the second transparent layer 55 are arranged on the surface (back surface) of the substrate 51 opposite to the viewing side. be. When the colored layer 52, the first transparent layer 53, the decorative member 54, and the second transparent layer 55 are provided on the back side of the substrate 51 as in this embodiment, as shown in FIG. , the colored layer 52 , the first transparent layer 53 , the decorative member 54 , and the second transparent layer 55 are formed on the back surface of the base material 51 in order from the lower surface side (opposite side of the viewing side) when the exterior member 5 is mounted on the timepiece 100 . Laminated on the side.

In this embodiment, the base material 51 is arranged on the outermost surface (viewing side surface) of the exterior member 5 .
The base material 51 is a plate-shaped transparent member made of a material with high transmittance, which allows the opposite side to be seen from the viewing side.
In this embodiment, the term “transparent” means that light can pass through and can be seen through, but it is not limited to being completely colorless and transparent as long as it has excellent light transmittance. For example, the concept includes semi-transparency.

When the exterior member 5 is the bezel member 2, the bezel member 2 borders the surface side of the timepiece 100, so it is preferably made of a hard material that can withstand scratches and wear. Specifically, as a material for forming the base material 51 constituting the bezel member 2, a material that is hard to be scratched, such as hard glass such as sapphire glass, is preferably used.
When the exterior member 5 is the dial plate 3, the base material 51 is preferably made of a highly transparent and relatively lightweight synthetic resin such as acrylic resin.
The material forming the base material of the exterior member 5 is not limited to those exemplified here.
Note that the shape and the like of the base material 51 are not particularly limited. The base material 51 is not limited to a flat plate shape, and may be formed in a three-dimensional shape having irregularities, curves, or the like.

The colored layer 52 is a layer with low transmittance formed of a material with low transmittance.
The material for forming the colored layer 52 is, for example, lacquer, a liquid agent such as ink containing a synthetic resin as a main component that can reproduce the black of lacquer (so-called “jet black”), or other layers with low transmittance (colored A variety of liquid agents from which layer 52) can be formed. Note that the color of the colored layer 52 is not limited to black, and each color can be selected as appropriate. One sheet of base material 51 may be painted in a plurality of colors.
The thickness of the colored layer 52 is not particularly limited, but the thickness should be such that the transmittance is sufficiently low and cracks do not occur when dried.

The first transparent layer 53 is provided in contact with the colored layer 52 and has a higher transmittance than the colored layer 52 .
The material forming the first transparent layer 53 is, for example, a transparent resin liquid agent.
As will be described later, the first transparent layer 53 is cured after forming the layer. For this reason, the material for forming the first transparent layer 53 is, for example, a resin having a high transmittance, and is preferably a thermosetting resin that cures with heat or a photocurable resin that cures with light (for example, UV). Applies to It should be noted that it is preferable that what is applied as the material for forming the first transparent layer 53 is appropriately determined according to compatibility with the surface on which the first transparent layer 53 is provided.
The first transparent layer 53 may be transparent in a dry state (cured state), and may have a low transmittance in a freshly applied state, for example.

The decorative member 54 is provided on the surface of the first transparent layer 53 opposite to the surface in contact with the colored layer 52 .
The decorative member 54 is various foils and powders such as gold powder, silver powder, platinum powder, and gold leaf used for maki-e. Note that the decorative member 54 is not limited to these. For example, it includes a wide range of precious stone fragments, glass fragments, seashells, and glitter.

The second transparent layer 55 has a higher transmittance than the colored layer 52 , and is in contact with the first transparent layer 53 to sandwich the decoration member 54 with the first transparent layer 53 .
The material for forming the second transparent layer 55 is not particularly limited, but as will be described later, the first transparent layer 53 is cured after forming the layer. For this reason, similarly to the first transparent layer 53, for example, a resin having a high transmittance such as a thermosetting resin that cures with heat or a photocurable resin that cures with light (for example, UV) is preferably applied. be done.

It should be noted that the material to be used for forming the second transparent layer 55 is preferably appropriately determined depending on compatibility with the surface on which the second transparent layer 55 is provided. In this embodiment, the second transparent layer 55 is provided in contact with the substrate 51 . Therefore, it is preferable that the material for forming the second transparent layer 55 is determined based on compatibility with the base material 51 (easiness of adhesion, strength of adhesion, etc.).
For example, when the base member 51 is made of glass or the like, as in the case where the exterior member 5 is the bezel member 2, thermosetting resin with high transmittance is used as the material for forming the first transparent layer 53. It is preferable to use Further, for example, when the base member 51 is made of resin, as in the case where the exterior member 5 is the dial 3 made of resin, the first transparent layer 53 may be made of a material having a high transmittance. It is preferable to use a photocurable resin (for example, a UV curable resin).
As with the first transparent layer 53, the second transparent layer 55 only needs to be transparent in a dry state (cured state). good.

Also, in this embodiment, the second transparent layer 55 is provided on the base material 51 and functions as an adhesive layer for fixing the decorative member 54 on the base material 51 . As in the present embodiment, when the second transparent layer 55 is provided prior to the decorative member 54 and has the function of adhering the decorative member 54, the material forming the second transparent layer 55 is It preferably has a viscosity of 0.1 mPa·S to 200 Pa·S.

Next, the method of manufacturing the exterior member 5 and the operation of the timepiece 100 including the same according to the present embodiment will be described.

FIG. 2(b) is a cross-sectional view of a principal part of the exterior member shown in FIG. 2(a) when the exterior member is turned upside down (front and back).
In FIG. 2(b), the substrate 51 on which the colored layer 52, the first transparent layer 53, the decorative member 54, and the second transparent layer 55 are provided is arranged at the bottom with the back side facing up. 4 shows the stacking order of each part in each case.

When manufacturing the exterior member 5 of the present embodiment, as shown in FIG. The second transparent layer 55 is formed as the first transparent layer by applying a material having a high transmittance such as a transparent adhesive to the back surface of the base material 51. (First transparent layer forming step).
Although the method of forming the second transparent layer 55 is not particularly limited, for example, silk screen printing (hereinafter referred to as “silk printing”) or the like is used.
As a material for forming the second transparent layer 55, a thermosetting resin, a photosetting resin, or the like is selected and used depending on compatibility with the material of the base material 51 as described above.

The material forming the second transparent layer 55 has a viscosity of 0.1 mPa·S to 200 Pa·S as described above, and starts to harden gradually after forming the layer.
In the present embodiment, before the second transparent layer 55 is completely cured, on the second transparent layer 55 (the side in contact with the substrate 51 is the opposite side, the upper side in FIG. 2B). The decoration member 54 is arranged (decoration member arrangement step).
Specifically, like the maki-e technique, the decorative members 54 such as metal powder such as gold powder and foil such as gold foil are placed or scattered on the second transparent layer 55 according to the design or the like.
If the second transparent layer 55 is too soft and easily flows, the decorative member 54 placed thereon moves or flows, which is undesirable. In this regard, when the second transparent layer 55 is formed of a liquid having a viscosity of 0.1 mPa·S to 200 Pa·S, it does not flow over the base material 51 and is appropriately applied on the surface of the base material 51. In addition to remaining there, it functions as an adhesive without being completely hardened for a period of time equivalent to the working time for arranging the decorative member 54 .

After placing the decorative member 54 , the second transparent layer 55 is cured by a method (heat curing or light curing) according to the material forming the second transparent layer 55 . For example, when the material forming the second transparent layer 55 is a thermosetting resin, the second transparent layer 55 can be completely cured by heating at 80 to 100 degrees for about 30 minutes. can.
It is not essential to completely cure the second transparent layer 55 before going to the next step (in this embodiment, the step of forming the first transparent layer 53). If the decorative member 54 applied on the second transparent layer 55 is hardened and temporarily fixed to such an extent that it does not flow or peel off in the next step, the next step may proceed before the complete hardening. In addition, when the next step (the step of forming the first transparent layer 53) uses a plate such as silk printing, the second transparent layer 55 and the decoration member 54 applied thereon are the plate. It must be hardened to the extent that it does not stick to the surface.

After the second transparent layer 55 is cured (completely cured or temporarily fixed), a material having a high transmittance such as a transparent resin is applied to form the second transparent layer, which is the first transparent layer. A first transparent layer 53 is formed as a second transparent layer that sandwiches the decorative member 54 between itself and the second transparent layer 55 in contact with the layer 55 (second transparent layer forming step).
Although the method of forming the first transparent layer 53 is not particularly limited, for example, silk printing or the like is used as in the case of forming the second transparent layer 55 .
Then, the first transparent layer 53 is cured by a method (thermal curing or photocuring) according to the material forming the first transparent layer 53 . As in the case of the second transparent layer 55, the curing in this case may be a temporarily fixed state that does not reach complete curing.
As a result, the decorative member 54 is sandwiched between two transparent layers (the first transparent layer 53 and the second transparent layer 55).
In this embodiment, the decoration member 54 is not arranged after the second transparent layer (that is, the first transparent layer 53) is formed. For this reason, compared with the case of forming the first transparent layer (that is, the second transparent layer 55), it can be cured more easily. Further, unlike the first transparent layer (ie, second transparent layer 55), the viscosity of the second transparent layer (ie, first transparent layer 53) is not particularly limited.

Finally, a colored layer 52 is formed from a material having a low transmittance in contact with the first transparent layer 53, which is the second transparent layer (colored layer forming step).
The colored layer 52 is formed by, for example, silk printing. Note that the method of forming the colored layer 52 is not particularly limited. For example, the colored layer 52 may be formed using various film-forming techniques such as inkjet printing, various coatings, and vapor deposition.
Then, the colored layer 52 is cured by a method (thermal curing or photocuring) according to the material forming the colored layer 52 . In this case, conditions are set so that each layer is completely cured, each layer formed on the base material 51 is completely cured, and the exterior member 5 is completed.

A set of the first transparent layer (that is, the second transparent layer 55) and the decorative member 54 may be provided by stacking a plurality of layers (a plurality of sets).
For example, a first transparent layer (that is, the second transparent layer 55) is formed on the back surface of the base material 51, the decorative member 54 is arranged, and then the second transparent layer 55 is further formed thereon. , a decorative member 54 may be arranged. In this case, the second transparent layer 55 is made to satisfy the same conditions as the first transparent layer (that is, the second transparent layer 55), such as viscosity. Then, before forming the colored layer 52, the first transparent layer 53 (that is, the above-mentioned "second transparent layer") is placed between the second transparent layer 55 and the decorative member 54 and the colored layer 52. set up.
In this case, the decoration member 54 arranged in any layer can be sandwiched between the transparent layers (the first transparent layer 53 or the second transparent layer 55), and the embedding of the decoration member 54 in the colored layer 52 can be prevented. can be prevented.
In this way, when a set of decorative members 54 sandwiched between transparent layers is provided in multiple layers, it is also possible to express a three-dimensional design with a sense of depth on the colored layer 52 formed of lacquer or the like. As a result, it is possible to realize the exterior member 5 having a more excellent design.

When the exterior member 5 is completed, it is turned upside down so that the base material 51 is on the front side (viewing side of the watch), as shown in FIG.
As a result, as shown in FIG. 1, the bezel member 2 and the dial 3 are decorated using a technique such as lacquer lacquer work to complete a timepiece 100 with excellent design.

As described above, according to the present embodiment, the exterior member 5 includes the colored layer 52 formed of a material with low transmittance, and the colored layer 52 provided in contact with the material having a higher transmittance than the colored layer 52. and a decorative member 54 provided on the surface of the first transparent layer 53 opposite to the surface in contact with the colored layer 52 .
FIG. 3 shows an example of the exterior member 7 in which a decorative member 64 such as gold dust is arranged directly on a colored layer 62 formed of lacquer, black ink, or the like. In this case, the decorative member 64 can be adhered and fixed to the base material 61 by a transparent layer 65 composed of a transparent adhesive or the like. However, as shown in FIG. or the colored layer 62 wraps around the viewing side of the decorative member 64.例文帳に追加For this reason, it became difficult to visually recognize the decorative member 64, and a beautiful decoration could not be realized.
In this regard, when a transparent layer (first transparent layer 53) is arranged between the colored layer 52 formed of lacquer, black ink, or the like and the decorative member 54 of gold powder or the like, as in the present embodiment, can prevent the decoration member 54 from being buried in the colored layer 52, and can also prevent the decoration member 54 from wrapping around the colored layer 52 to the viewing side. In addition, since the layer interposed between the colored layer 52 and the decorative member 54 is a transparent layer (first transparent layer) formed of a material with high transmittance, the decorative member can be seen with the colored layer 52 as the background. It does not interfere with the appearance of 54. As a result, the decorative member 54 stands out clearly against the background of the colored layer 52, and the exterior member 5 with a more beautiful appearance can be realized.

In addition, the exterior member 5 of the present embodiment further includes a base material 51 made of a material with high transmittance that allows the opposite side to be seen from the viewing side, and includes a colored layer 52, a first transparent layer 53, And the decorative member 54 is arranged on the surface of the base material 51 opposite to the viewing side.
By applying the decoration from the back surface side of the base material 51 in this manner, it is possible to prevent damage and deterioration even if it receives an impact from the outside. Thereby, the exterior member 5 with a long and beautiful appearance can be enjoyed.

Further, in this embodiment, the second transparent layer 55 is formed of a material having a higher transmittance than the colored layer 52 and is in contact with the first transparent layer 53 to sandwich the decorative member 54 between itself and the first transparent layer 53 . is further provided.
Therefore, the decorative member 54 can be confined and stabilized in the transparent layer, and the beautiful state at the time of manufacture can be maintained for a long period of time. Further, when the decorative member 54 is configured to be enclosed in a transparent layer, even a relatively heavy object such as a precious stone or glass piece can be held in place, thereby increasing the variety of decorations.

Further, in the exterior member 5 of the present embodiment, the material forming the second transparent layer 55 has a viscosity of 0.1 mPa·S to 200 Pa·S.
In this embodiment, a decorative member 54 is provided on the second transparent layer 55 . At this time, if the second transparent layer 55 is in a state where it is easy to flow, the decorative member 54 that has been placed with much effort will be washed away and will not be able to stay in the intended position. In this regard, by forming the second transparent layer 55 with a material having a certain viscosity, the decorative member 54 can be arranged as intended. In addition, the second transparent layer 55 can be satisfactorily formed by silk printing or the like. Furthermore, although the second transparent layer 55 gradually hardens after being formed, it does not completely harden during the operation of disposing the decorative member 54, and workability is excellent.

In addition, when the exterior member 5 is configured as the dial 3 as in the present embodiment, it is possible to realize a beautiful and high-class appearance as if the lacquer work was applied to the most conspicuous part of the watch or the like. .

In addition, when the exterior member 5 is configured as the bezel member 2 as in the present embodiment, the most conspicuous part of the watch or the like, like the dial 3, has a beautiful and high-class appearance as if lacquer work was applied. can be realized.

When the exterior member 5 of the present embodiment is applied to a timepiece 100 as an electronic device, decoration such as lacquer work (decorative member 53) applied to the exterior member 5 such as the bezel member 2 and the dial 3 may be lacquer or black. It becomes clearly visible without being buried in the colored layer 55 formed of ink.
As a result, it is possible to realize a timepiece that has a beautiful appearance, a sense of quality, and excellent design.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and it goes without saying that various modifications are possible without departing from the scope of the invention.

For example, in the present embodiment, as shown in FIG. 2A, a case where a colored layer 52, a first transparent layer 53, a decorative member 54, and a second transparent layer 55 are provided on the back side of a substrate 51 is illustrated. However, the configuration of the exterior member is not limited to this.
For example, as shown in FIG. 4, the exterior member 7 may have a colored layer 72, a first transparent layer 73, a decorative member 74, and a second transparent layer 75 provided on the surface side of a base material 71. good.
In this case, the exterior member 7 is formed by sequentially stacking the layers on the base material 71 from the lower layer shown in FIG.

As shown in FIG. 5, the exterior member 8 is configured by placing a decorative member 84 such as gold powder directly on a colored layer 82 formed of lacquer, black ink, or the like, and forming a transparent layer 83 thereon. Then, although the surface on which the decorative member 84 is provided can be protected by the transparent layer 83, the decorative member 84 may be buried in the colored layer 82, or the colored layer 82 may be on the visible side of the decorative member 84. I end up going around. For this reason, it becomes difficult to visually recognize the decorative member 84, and a beautiful decoration cannot be realized.
In this respect, as shown in FIG. 4, when a transparent layer (first transparent layer 73) is arranged between a colored layer 72 formed of lacquer, black ink, or the like and a decoration member 74 made of gold powder or the like, can prevent the decoration member 74 from being buried in the colored layer 72, and can also prevent the decoration member 74 from wrapping around the colored layer 72 to the viewing side. In addition, since the layer interposed between the colored layer 72 and the decorative member 74 is a transparent layer (first transparent layer) formed of a material with high transmittance, the decorative member can be seen with the colored layer 72 as the background. Does not interfere with the appearance of 74. As a result, the decoration member 74 stands out clearly against the background of the colored layer 72, and the exterior member 7 with a more beautiful appearance can be realized.

When decoration is applied to the front side of the base material as shown in FIG. 4, the base material 71 may not be a transparent member, and may be, for example, a metal plate. For example, the surface of the band attachment portion 12 of the watch case 1 made of metal or the like, the side surface of the watch case 1, or the like is used as the base material 71, and a colored layer 72, a first transparent layer 73, a decorative member 74, and the like are formed on the base material 71. The second transparent layers 75 may be provided one after the other.
By providing the colored layer 72 or the like on the metal base material, it is possible to create a texture different from that of the portion where the colored layer 72 or the like is not provided. Also, by arranging the decorative member 74 on the colored layer 72 of lacquer, black ink, or the like, it is possible to realize a beautiful appearance with outstanding contrast rather than directly on metal or the like.
Also, for the bezel member 2 and the dial 3 shown in this embodiment, a colored layer, a first transparent layer, a decorative member, and a second transparent layer may be provided on the surface side of the base material 51 .

When the front side of the base material 71 is decorated in this manner, the first transparent layer 73 is provided prior to the decorative member 74 and has the function of adhering the decorative member 74 . In this case, the material forming the first transparent layer 73 preferably has a viscosity of 0.1 mPa·S to 200 Pa·S.

In the present embodiment, the dial 3 is of an analog type that has hour characters 31 and displays the time and the like by means of hands 32, but the dial 3 is not limited to the analog type. A digital system including a panel or the like, or a combination of an analog system and a digital system may be used.

Further, in the present embodiment, the case where the exterior member 5 is provided in the timepiece 100 was illustrated, but the electronic device in which the exterior member 5 is provided is not limited to the timepiece.
For example, the exterior member 5 of the present invention may be applied to pedometers, heart rate meters, altimeters, barometers, so-called smart watches, and the like.
