Description

  INDUSTRIAL APPLICABILITY The present invention is used for solar cell devices such as solar clocks equipped with solar power generation devices composed of solar cells (solar cells), desk calculators, automobiles, airplane instrument panels, mobile devices such as mobile phones, and the like. The present invention relates to a display board disposed above a solar power generator.

  More specifically, the present invention provides window frame members that surround the outer periphery of the window frame opening for displaying indicators such as day of the week and date, time such as hours, minutes, and seconds, or measurement data such as pressure and temperature. The present invention relates to a display board provided with an additional member such as an indicator member for displaying, a decorative member for decorating the display board, or an identification member for identifying a product such as a company name, brand name, pet name, manufacturer name, or the like.

  2. Description of the Related Art In recent years, solar cell devices, particularly watches, have a solar power generation device including a solar cell (solar cell), and solar watches driven by the power generated by the solar power generation device have become a major market. .

Such a display plate (dial plate) for a solar timepiece is configured to transmit received light and cause a power generation function to occur in a solar power generation device disposed on the lower surface side thereof.
Therefore, a display panel for a solar watch is required to have a certain degree of light transmittance because it transmits light outside the wavelength range that contributes to power generation of the solar power generation device and gives an electromotive force to the solar power generation device. Need to be translucent.

  For this reason, a substrate constituting a display panel for a solar watch is manufactured as a transparent or translucent part by using a soft material such as synthetic resin, paper, cloth, or a brittle material represented by ceramic such as glass. ing.

  On the other hand, a window frame member is arranged on the display panel for the solar timepiece so as to surround the outer periphery of the window frame opening so that a calendar display unit for displaying an indicator such as a day of the week or a date can be seen from above. ing.

  In this case, the window frame member is desired to be made of metal for the reason of giving the user who looks at the display board an aesthetic appearance and a high-class feeling, and such a metal window frame member is preferably made of a soft material or a brittle material. Various means have been proposed for securely fixing to the display panel. For example, a metal window frame member is fixed to a display panel made of a soft material or a brittle material by a method such as press fitting or caulking. Has been done.

  However, since the metal window frame member cannot be firmly fixed to the display board by a method such as press fitting or caulking, for example, when a large impact is applied to the display board, the window frame member is not attached to the display board. There was a risk of falling off.

  For this reason, conventionally, in Patent Document 1 (Japanese Patent Laid-Open No. 2001-42055), as shown in FIGS. 10 to 12, the window frame opening portion of the substrate 102 made of a soft material or a brittle material constituting the display panel 100. A structure in which a metal window frame member 108 bites and fixes to the inner wall 106 of 104 is proposed.

In other words, the window frame member 108 includes a frame main body 110 inserted into the window frame opening 104 and a decorative edge 101 continuous above the frame main body 110. On the outer periphery of the frame main body 110, a protrusion 112 protruding outward is formed. The decorative edge 101 extends in a flange shape along the planar direction from the frame main body 110 and is formed in a size that cannot pass through the window frame opening 104. The frame main body 110 and the decorative edge 101 are both cut in the vertical direction, and a through window 103 penetrating vertically through the frame main body 110 and the decorative edge 101 is formed.

The window frame member 108 is fixed to the substrate 102 as follows.
The frame main body 110 of the window frame member 108 is inserted into the window frame opening 104 of the substrate 102. Then, the projection 112 of the frame main body 110 is immersed in the inner wall 106 of the window frame opening 104, and the frame main body 110 is fixed in the window frame opening 104. The decorative edge 101 is in contact with the upper surface of the substrate 102 and is located above the substrate 102.

  An observer who watches the clock reads, for example, the date and day of the week on the calendar display unit operating under the substrate 102 through the through window 103 of the window frame member 108. Here, the portions touched by the observer are the upper surface of the decorative edge 101 surrounding the date and day of the calendar display section, and the inner wall of the through window 103. In this case, since the upper surface of the decorative edge 101 and the inner wall of the through window 103 are made of metal, a high-class aesthetic appearance is given to the observer.

A protrusion 112 projecting outward is formed on the outer periphery of the through-hole 110 penetrating the window frame opening 104, and the protrusion 112 is immersed in the inner wall 106 of the window frame opening 104. ), And the window frame member 108 is configured to be fixed to the window frame opening 104.
JP 2001-42055 A

  However, in the display panel 100 of Patent Document 1, when the substrate 102 is made of a soft material, if the projection 112 of the window frame member 108 is immersed in the inner wall 106 of the window frame opening 104, the window frame opening 104 is surrounded by the periphery of the window frame opening 104. When the distortion occurs and the periphery of the window frame opening 104 is discolored or is severe, plastic deformation may occur. As a result, the aesthetic appearance of the display panel 100 is significantly impaired.

  Further, when a large impact force is applied to the display panel 100 from the outside, the substrate 102 itself is elastically deformed, so that the projection 112 of the window frame member 108 falls off the inner wall 106 of the window frame opening 104. Will end up. As a result, the window frame member 108 often dropped from the substrate 102 due to an impact.

  On the other hand, when the substrate 102 is made of a brittle material, if the protrusion 112 of the window frame member 108 is immersed in the inner wall 106 of the window frame opening 104, the display panel made of the brittle material has cracks around the window frame opening 104. If the window frame opening 104 is severely damaged, the periphery of the window frame opening 104 may be damaged or chipped. As a result, the aesthetic appearance of the display panel 100 is significantly impaired.

On the other hand, on the display board, in addition to the additional member consisting of a window frame member surrounding the outer periphery of the window frame opening 104 for displaying the indicators such as the day of the week and the date as described above,
(1) An indicator member for displaying time, such as hours, minutes, seconds, or measurement data such as pressure or temperature,
(2) a decorative member for decorating the display board, or
(3) Identification members for identifying products such as company name, brand name, pet name, manufacturer name,
It is usual to attach additional members, such as.

Even when these additional members are attached to the substrate, the same problem as in Patent Document 1 has occurred.

In view of such a current situation, the present invention is such that even if the display panel itself is elastically deformed by an impact load, the window frame member does not fall off the display panel, and the additional member is not subjected to a large mechanical load on the display panel. An object of the present invention is to provide a display panel that can be firmly fixed to the display panel, is excellent in strength, has a good aesthetic appearance, and has a high-class feeling.

The present invention was invented in order to achieve the above-described problems and objects in the prior art, and the display panel of the present invention is a display panel disposed above a solar power generation device of solar cell equipment. Because
A translucent substrate disposed above the solar power generation device and capable of transmitting light from the outside;
An additional member disposed above the translucent substrate;
A penetrating portion formed in the additional member and penetrating the translucent substrate;
A support member disposed below the translucent substrate and fixing the additional member;
It is characterized by providing.

  In the present specification, “vertical direction” means the vertical direction in FIG. Therefore, the upper surface is a surface exposed outward when the wristwatch is worn on the wrist, and the lower surface is a surface facing the wrist in the same state.

  Further, the “planar direction” is a direction orthogonal to the vertical direction, and in FIG. 1, means the front side of the paper surface and the back side of the paper surface, and the planar direction is the longitudinal direction of the band, or It may overlap with the width direction of the band.

  By comprising in this way, an additional member is arrange | positioned above a translucent board | substrate, the penetration part formed in the additional member was penetrated to the translucent board | substrate, and it was arrange | positioned under the translucent board | substrate. The additional member can be easily and firmly fixed via the support member.

  Therefore, even when the substrate constituting the display panel is made of a soft material, no load is applied to the substrate, so that the surroundings are not distorted, the surroundings of the additional member are not discolored, and are plastically deformed. In no case, the aesthetic appearance of the display board is not impaired.

  In addition, even when the substrate constituting the display panel is made of a brittle material, no load is applied to the substrate, so that no crack is generated around the additional member, and the peripheral portion of the additional member is damaged and damaged. There is no loss, no loss, and the aesthetic appearance of the display board is not impaired.

  Therefore, even if the substrate itself is elastically deformed by an impact load, the additional member does not fall off the substrate, and the additional member can be firmly fixed to the display board without applying a large mechanical load to the substrate. It is possible to provide a display panel which is excellent, has a good appearance, and has a high-class feeling.

  In this case, the display panel provided with the substrate having the window frame opening is composed of a light-transmitting substrate made of a soft material or a brittle material, for example, a solar power generation device made of a solar cell (solar cell). Is used for solar cell equipment such as a solar watch equipped with a solar power generator and a desktop calculator using a solar power generator, and when used as a display plate placed above the solar power generator, It is desirable for causing the solar power generation device disposed on the lower surface side to generate a power generation function.

  Further, the thickness of the substrate constituting the display plate is preferably 30 μm to 1000 μm. If the thickness is in such a range, for example, when used as a display plate for a wristwatch, the watch is thinned. For this reason, even if the thickness of the substrate is reduced, it can be processed without lowering the mechanical strength. Further, since the thickness of the substrate is too thick, it is possible to indicate an accurate time without the timepiece hand swinging, and the thickness of the timepiece itself can be made compact.

  Furthermore, if the thickness of the substrate is in such a range, for example, when used as a display plate for solar devices such as a display plate for a solar watch, it contributes to power generation without reducing the light transmittance. It is possible to secure the driving force of the equipment, etc., and the cross line that is the boundary line of the solar cell arranged below the display board and dark purple are erased, and the color tone of the solar cell is not visually recognized Can be.

Note that the substrate may be formed by combining the above-described soft material and brittle material in a planar or multilayer manner.
Furthermore, the soft material constituting the substrate is not particularly limited, and for example, synthetic resin, paper, cloth, or the like can be used. The brittle material constituting the substrate is not particularly limited, and for example, cloisonne, ceramics such as glass, shells such as white butterfly shells, and the like can be used.

On the other hand, the material constituting the support member is not particularly limited, but considering the strength for fixing the additional member, it is desirable to use a hard material or a ductile material, particularly a metal. Gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or alloys thereof are employed. Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like may be employed.
Even if discoloration, distortion, cracks, etc. occur in the support member due to the fixing of the additional member, they are hidden by the substrate and are not visually recognized from the outside as long as they do not cause a significant hindrance to the fixing strength of the additional member. Therefore, the appearance of the display board is not impaired. Therefore, the material constituting the support member may be a soft material or a brittle material as long as the fixing strength of the additional member can be obtained. For example, the material constituting the support member may be a synthetic resin.

In the display panel of the present invention, the translucent substrate is formed with a mounting through hole formed so as to penetrate the translucent substrate.
In this way, if the mounting through hole formed so as to penetrate the translucent substrate is formed, the through portion formed in the additional member may be passed through the mounting through hole of the translucent substrate. Therefore, no load is applied to the substrate, and the additional member can be easily and firmly fixed via the support member disposed below the light-transmitting substrate.

Moreover, the display board of the present invention is characterized in that a mounting through-hole through which the penetrating portion of the additional member passes is formed in the support member.
In this way, if the through hole for attachment through which the through portion of the additional member passes is formed in the support member, the through portion formed in the additional member may be passed through the through hole for attachment of the support member. No load is applied to the support member, and the support member is not damaged or damaged, and the additional member can be easily and firmly fixed through the support member disposed below the light-transmitting substrate.

The display panel of the present invention is characterized in that the mounting through-hole formed so as to penetrate the translucent substrate is a window frame opening.
By comprising in this way, a window frame member is arrange | positioned as an additional member above a translucent board | substrate, and the penetration part formed in the window frame member is penetrated to the window frame opening part of a translucent board | substrate. The window frame member can be easily and firmly fixed as the additional member via the support member disposed below the translucent substrate.

In the display panel of the present invention, the mounting through hole formed so as to penetrate through the support member is a window frame opening.
With this configuration, the window frame member is disposed as an additional member above the translucent substrate, and the penetration portion formed in the window frame member is caused to penetrate the window frame opening portion of the support member. The window frame member can be easily and firmly fixed as the additional member via the support member disposed below the optical substrate.

It is characterized by providing.

  By configuring in this way, light from the outside that has passed through the translucent substrate can be passed through the opening toward the solar power generation device. Even when used as a display panel for devices, it can contribute to power generation without lowering the light transmittance, and the driving force of the devices can be ensured.

  Further, with this configuration, a material that does not transmit light or is difficult to transmit can be selected as the material for the support member. For example, since the material of the support member can be metal, the additional member can be firmly fixed to the support member.

Further, the display panel of the present invention is characterized in that the opening is arranged in the vicinity of the upper part of an antenna for receiving radio waves from outside the solar cell devices.
By arranging the opening in the vicinity of the upper part of the antenna in this way, for example, when a display plate is used for a wireless function watch, there is no conductive support member that prevents reception of radio waves above the antenna. Therefore, the receiving sensitivity of the antenna is improved.
Further, with this configuration, a material that does not transmit or hardly transmits radio waves can be selected as the material for the support member. For example, since the material of the support member can be metal, the additional member can be firmly fixed to the support member.

  In the display panel of the present invention, the opening has two openings disposed in the vicinity of the upper part of the antenna so as to face both open ends of the antenna for receiving radio waves from outside the solar cell devices. It is characterized by providing.

With this configuration, for example, when a display board is used for a wireless function watch, the conductive support that prevents reception of radio waves by two openings is provided in the portion facing the open ends of the antenna. Since there is no member, radio waves are received at the open end of the antenna through these openings, and the reception sensitivity of the antenna is improved.
Further, with this configuration, a material that does not transmit or hardly transmits radio waves can be selected as the material for the support member. For example, since the material of the support member can be metal, the additional member can be firmly fixed to the support member.

  In the display panel of the present invention, the opening is disposed in the vicinity of the upper part of the antenna so as to face at least one open end of the antenna for receiving radio waves from outside the solar cell devices. It comprises a part.

With this configuration, for example, when a display board is used for a wireless function watch, a portion facing at least one open end of the antenna has a conductive property that prevents reception of radio waves by an opening. Since there is no support member, radio waves are received at one open end of the antenna through this opening, and the reception sensitivity of the antenna is improved.
Further, with this configuration, a material that does not transmit or hardly transmits radio waves can be selected as the material for the support member. For example, since the material of the support member can be metal, the additional member can be firmly fixed to the support member.

Further, the display plate of the present invention is characterized in that a transmissive reflecting plate is disposed on the lower surface of the support member.
As described above, by arranging the transmissive reflector on the lower surface of the support member, the display member as a whole has a precious metal feeling rich in decoration, and the opening provided in the support member acts as the transmissive reflector. It can be made inconspicuous and not feel uncomfortable.

Dry plating by vacuum deposition, sputtering, ion plating, etc. on resin films such as polyethylene terephthalate resin film and polyimide resin film. A film plate, a reflective polarizing plate, or the like having a metal thin film formed by a method and having both functions of transparency and reflection can be used as the transmission reflector.

  Moreover, the light-transmitting plate in which the metal thin film is formed by the dry plating method can freely set the light transmittance by changing the thickness of the metal film. This transmissive reflector is provided to make the dark purple color of the solar cell invisible so that the light reflected from the solar cell is transmitted to the display surface and emitted, and the transmissive reflector has It is provided in order to soften the deep purple color.

  As the color tone of the transmissive reflector, it is preferable to select a color tone similar to the color tone of the support member. If the colors are similar, the presence of the opening of the support member will not be noticeable, and the user will not feel uncomfortable.

  Light incident from the opening of the support member passes through the transmissive reflector and enters the solar cell. However, since the light reflected by the transmissive reflecting plate also appears, the transmittance decreases. Therefore, the size and area of the opening of the support member are set in consideration of the transmittance of the transmissive reflector. The thickness of the transmissive reflector is preferably 50 to 300 μm.

  When a reflective polarizing plate is used as the transmissive reflective plate, the reflective polarizing plate has a reflection axis N and an easy transmission axis M as shown in FIG. The linearly polarized light component having a parallel vibration surface is reflected, and the linearly polarized light component having a vibration surface parallel to the easy transmission axis M is transmitted. Further, it has a characteristic of transmitting about 50% of light and reflecting about 50% of light.

  For example, by using the product name “DBEF” manufactured by Sumitomo 3M Co., Ltd., it is possible to obtain a strong reflected light exhibiting a glossy silver color (silver color). Some of the reflective polarizing plates can obtain a reflected light exhibiting a gold color in addition to a silver color.

  By disposing the transmissive reflecting plate on the lower surface of the support member in this manner, the display panel as a whole exhibits a silver color and a precious metal feeling rich in decoration. Further, the opening provided in the support member is hardly noticeable due to the action of the transmissive reflecting plate from which silver-colored reflected light is obtained, and does not feel uncomfortable.

In the display panel of the present invention, the light-transmitting substrate and the support member are fixed via a bonding layer.
In the display panel of the present invention, the bonding layer is composed of at least one bonding layer selected from an adhesive, a pressure-sensitive adhesive, and a bonding tape.

  In addition, as shown in FIGS. 1-3, FIG. 10, the part divided by the four radial support parts 40c-40f of the support member 40 respond | corresponds to the four fan-shaped solar cell parts 23a-23d. Thus, four fan-shaped openings 41a to 41d are formed, and light from the outside that has passed through the translucent substrate passes through these openings 41a to 41d toward the solar power generation device. It can be made to.

By configuring in this way, light from the outside that has passed through the translucent substrate 32 can be passed through the openings 41 a to 41 d toward the solar power generation device 22. Even when used as a display panel for solar devices such as display panels, it can contribute to power generation without lowering the light transmittance, and the driving force of the devices can be secured. The display panel 24 provided with the translucent substrate 32 having the frame opening 36 is composed of a translucent substrate made of a soft material or a brittle material, for example, a solar cell (solar cell) composed of a solar cell. Used for solar cell equipment such as solar watches equipped with power generators, desktop calculators using solar power generators, etc., and used as a display plate placed above the solar power generators In this case, it is desirable to transmit the received light and cause the solar power generation device disposed on the lower surface side to generate a power generation function.

  Further, the thickness of the translucent substrate 32 constituting the display plate 24 is desirably 30 μm to 1000 μm. If the thickness is within such a range, for example, when used as a display plate for a wristwatch. In order to reduce the thickness of the timepiece, even if the thickness of the light-transmitting substrate 32 is reduced, it can be processed without lowering the mechanical strength. Further, since the thickness of the translucent substrate 32 is too thick, it is possible to indicate an accurate time without the timepiece of the timepiece swinging, and the thickness of the timepiece itself can be made compact.

  Furthermore, if the thickness of the translucent substrate 32 is in such a range, for example, when used as a display plate of solar equipment such as a solar watch display plate, the light transmittance does not decrease, It can contribute to power generation, ensure the driving force of equipment, etc., and erase the cross-hairs and dark purple that are the boundary lines of the solar cells arranged below the display panel 24, so that the solar cells Can be prevented from being visually recognized.

The translucent substrate 32 may be formed by combining the above-described soft material and brittle material in a planar manner or in multiple layers.
Further, the soft material constituting the translucent substrate 32 is not particularly limited, and for example, synthetic resin, paper, cloth, or the like can be used. The brittle material constituting the substrate is not particularly limited, and for example, cloisonne, ceramics such as glass, shells such as white butterfly shells, and the like can be used.

  On the other hand, as a material constituting the metal window frame member 38, for example, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof is employed. Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like may be employed.

  On the other hand, the material constituting the support member 40 is not particularly limited, but is preferably made of metal in consideration of the strength for fixing the additional member, for example, gold, silver, copper, Brass, aluminum, magnesium, zinc, titanium, or alloys thereof are employed. Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like may be employed.

Below, the process of assembling the display board 24 comprised in this way is demonstrated based on FIGS. 4-7, FIG.
First, as shown in FIG. 4, the window frame opening 36 of the translucent substrate 32 and the window frame opening 40 g of the support member 40 are matched, and as shown in FIGS. The conductive substrate 32 and the support member 40 are fixed to each other via the bonding layer 42 (see FIG. 11).

In this case, it is desirable that the bonding layer 42 is composed of at least one bonding layer selected from an adhesive, a pressure-sensitive adhesive, and a bonding tape (double-sided tape).
Thus, since the translucent substrate 32 and the support member 40 are fixed via at least one bonding layer selected from an adhesive, an adhesive, and a bonding tape, the window frame member 38 that is an additional member, The translucent board | substrate 32 and the supporting member 40 can be firmly fixed integrally, and the display board 24 can be comprised as a whole.

  After the translucent substrate 32 and the support member 40 are fixed to each other via the bonding layer 42, as shown by the arrows in FIG. It penetrates so that the window frame opening part 36 of the translucent board | substrate 32 to comprise and the window frame opening part 40g of the supporting member 40 may be penetrated.

  In this state, as shown in FIGS. 7 and 9, the flange frame portion 38 a of the window frame member 38 is locked to the upper surface of the outer periphery of the window frame opening 36 of the translucent substrate 32, and the window frame The member 38 is prevented from falling downward.

  Next, as shown in FIGS. 6 and 9, from the lower surface (back surface) side of the translucent substrate 32 and the support member 40, the outer peripheral edge portion of the lower end portion of the through portion 38 b of the window frame member 38, and the support member Laser welding is performed between the inner periphery of 40 window frame openings 40g to form welds 44. Thereby, the window frame member 38 is fixed to the translucent substrate 32 by the support member 40.

In this embodiment, laser welding is performed, but other carbon dioxide welding and brazing can of course be performed.
By configuring in this way, the window frame member 38 which is an additional member is arranged above the translucent substrate 32, and the through portion 38 b formed in the window frame member 38 is made to pass through the window frame of the translucent substrate 32. The window frame member 38 is easily and firmly fixed through the support member 40 disposed below the translucent substrate 32 through the opening 36 and the window frame opening 40g of the support member 40. be able to.

Two openings 41a and 41b are provided.

  With this configuration, for example, when the display plate 24 is used in the solar timepiece 10 with a wireless function, the opening 26 a and 26 b facing the open end portions 26 a and 26 b of the antenna 26 are provided with two openings 41 a and 41 b. Since there is no conductive support member 40 that prevents reception of radio waves, radio waves are received by the open ends 26a and 26b of the antenna through these openings 41a and 41b, and the reception sensitivity of the antenna is improved. become.

  Although not shown, in the solar timepiece 10 with a wireless function, the solar timepiece 10 with a radio function is disposed in the vicinity of the upper portion of the antenna 26 so as to face at least one open end portion 26a (26b) of the antenna 26 for receiving external radio waves. You may make it provide the opening part 41a (41b).

FIG. 20 is a top view for explaining a state in which the display board of another embodiment of the present invention is incorporated in a solar wristwatch with a wireless function, and FIG. 21 is an exploded perspective view showing the display board of another embodiment of the present invention. FIG. 22 is a partially enlarged cross-sectional view showing a display panel according to another embodiment of the present invention, and FIG. 23 is a schematic view for explaining the operation of the reflective polarizing plate.

The display board 24 of this embodiment has basically the same configuration as that of the display board 24 shown in FIGS. 1 to 11, and the same constituent members are denoted by the same reference numerals and detailed description thereof is omitted. Description is omitted.
In the display plate 24 of this embodiment, a plurality of small holes 60 that are substantially circular openings are formed in the support member 40 in a top view penetrating in the vertical direction (thickness direction). A transmissive reflector 64 is disposed on the lower surface of the support member 40.

  As described above, by arranging the transmissive reflector 64 on the lower surface of the support member 40, the display member as a whole has a precious metal feeling rich in decoration, and the small holes 60 that are openings provided in the support member 40 are formed. The transmissive reflector 64 can be made inconspicuous and not feel uncomfortable.

  The transmissive reflector 64 has both light transmissive and reflective functions, and is a dry-type method using a vacuum deposition method, a sputtering method, an ion plating method, or the like on a resin film such as a polyethylene terephthalate resin film or a polyimide resin film. A film plate or a reflective polarizing plate formed by forming a metal thin film by a plating method and having both a transmissive and reflective function can be used as the transmissive reflective plate 64.

  Moreover, the light-transmitting plate 64 on which the metal thin film is formed by the dry plating method can freely set the light transmittance by changing the thickness of the metal film. This transmissive reflecting plate 64 is provided to make the dark purple color of the solar cell 23 invisible, and reduces the light transmitted from the solar cell 23 to the display surface side and emitted, and the transmissive reflecting plate. It is provided to soften the deep purple with the color tone of 64.

  For the color tone of the transmissive reflector 64, it is preferable to select a color tone of the same color as that of the guiding and supporting member 40. If the colors are similar, the presence of the small holes 60 that are the openings of the support member 40 becomes inconspicuous, and a sense of incongruity is not felt.

The light incident from the small hole 60 that is the opening of the support member 40 passes through the transmissive reflector 64 and enters the solar cell 23 as indicated by an arrow A in FIG.
However, as indicated by the arrow B, since the light reflected by the transmissive reflector 64 also appears, the transmittance decreases. Therefore, the size and area of the small hole 60 that is the opening of the support member 40 are set in consideration of the transmittance of the transmissive reflector 64. The thickness of the transmissive reflector 64 is preferably 50 to 300 μm.

  In this embodiment, the transmissive reflecting plate 64 is a reflective polarizing plate having a thickness of 130 μm. As shown in FIG. 23, the reflection type polarizing plate has a reflection axis N and an easy transmission axis M, and a linearly polarized light component having a vibration plane parallel to the reflection axis N is reflected. A linearly polarized light component having a parallel vibration surface has a transmission characteristic. Further, it has a characteristic of transmitting about 50% of light and reflecting about 50% of light.

  In this embodiment, the product name “DBEF” manufactured by Sumitomo 3M Co. is used to obtain a strong reflected light exhibiting a glossy silver color (silver color). Some of the reflective polarizing plates can obtain a reflected light exhibiting a gold color in addition to a silver color.

  By disposing the transmissive reflecting plate 64 on the lower surface of the support member 40 in this way, the display plate 24 as a whole exhibits a silver color and exhibits a precious metal feeling rich in decoration. Further, the small holes 60 provided in the support member 40 are hardly conspicuous under the action of the transmissive reflector 64 from which silver-colored reflected light is obtained, and do not feel uncomfortable.

  Further, as shown in FIG. 20, at least one of the many small holes 60 provided in the support member 40 faces one open end portion 26 a of the antenna 26 accommodated below the display panel 24. And it is arrange | positioned in the upper vicinity of the open end part 26a. Furthermore, it is preferable that the other open end portion 26 b of the antenna 26 is also arranged to face at least one of the small holes 60.

  By providing the small hole 60 in such a form, radio waves incident from above the display plate 24 are transmitted through the small hole 60 and are formed at the open end portions 26a and 26b of the antenna 26 at positions facing the small hole 60, respectively. Therefore, the antenna 26 can receive a predetermined radio wave with good sensitivity.

  In this embodiment, the small hole 60 is not limited to the shape shown in FIGS. For example, as shown in FIG. 24, a slit 66 may be inserted in a direction orthogonal to the antenna 26. Although not shown, a slit may be formed radially from the center of the support member 40, or a combination of a slit entering radially from the center of the support member 40 and a slit entering concentrically from the center of the support member 40. I do not care.

  Even in the case of the small hole 60 provided in this way, if the small hole 60 faces the at least one open end portion 26a of the antenna 26 and is disposed in the vicinity of the upper end of the open end portion 26a, the display board Since the radio wave incident from above 24 passes through the small hole 60 and reaches the open end 26a of the antenna 26 at a position facing the small hole 60, the antenna 26 can receive a predetermined radio wave with good sensitivity. The external light having a wavelength that contributes to the power generation of the solar cell 23 can be taken in enough to drive the movement 20.

  In the above embodiment, the window frame member 38, the indicator member 46, and the decoration member 48 are used as the additional members. However, the identification member for identifying the product such as the company name, the brand name, the pet name, and the manufacturer name. The present invention can also be applied to attach other additional members such as, but is not limited at all.

The preferred embodiment of the present invention has been described above, but the present invention is not limited to this. For example, in the above embodiment, the display plate of the present invention is a solar cell (solar cell). Although applied to a solar watch equipped with a power generation device, it can also be used for solar cell devices such as a desktop calculator using a solar power generation device.
