[0001]
BACKGROUND OF THE INVENTION
  The present invention is used for a clock display board and the like.Structure of electronic watch with hologram display plateIt is about.
[0002]
[Prior art]
  Conventionally, solar cells have been used as power sources for watches, calculators, portable radios, and the like. This solar cell is usually formed of amorphous silicon or the like and converts light energy into electric energy, and it is necessary to dispose it at a position where light hits, that is, a surface position directly visible from the outside.
[0003]
  7 and 8, when the solar cell is used for the display panel structure of the wristwatch, four fan-shaped solar cells 32 and an insulation band 33 are formed on the upper surface of the watch module 31 in plan view. A transparent polycarbonate or acrylic resin transparent plate 34 is laminated on the solar cell 32, and time letters 35, pet names, etc. are formed on the surface of the transparent plate 34 by printing or the like.
[0004]
  However, the aboveofIn such a solar clock display board structure, since the solar cell 32 is usually brown or dark blue, the display board has the above-mentioned color, and there is an insulating band 33 between the solar cell 32 and the solar cell 32. For this reason, the insulating band 33 appears as a crosshair, and the design including the color tone is not only greatly limited, but the product quality is poor.
[0005]
  On the other hand, a timepiece or the like has been proposed in which an interference filter or the like is provided on the front surface of the solar cell so that the solar cell cannot be directly seen. However, there is a problem that the optical energy supply to the solar cell is hindered. There was a problem that the appearance quality as a dial was poor.
[0006]
  In order to solve such a problem, for example, Japanese Patent Publication No. 5-38464 discloses a solar cell and a color that is provided in front of the solar cell and transmits light in a wavelength region that contributes to power generation of the solar cell. A colored solar cell having a filter, and a color diffusion layer that is provided between the solar cell and the color filter and includes a scattering layer that transmits part of the light transmitted by the color filter and scatters the rest in all directions It is disclosed.
[0007]
  When the scattering layer is a white diffusion plate, an acrylic milky white plate, a half mirror with a matte clear lacquer applied, a mirror made of aluminum or the like on the opposite side of glass or plastic roughened on one side It is shown that things are used.
[0008]
[Problems to be solved by the invention]
  However, in the above prior art, the acrylic milky white plate is preferred as a display plate for a wristwatch, and it has not been possible to obtain a metal color tone that can give a high-class feeling. Also, for the half mirror with a matte clear lacquer applied, or with a mirror made of aluminum or the like on the opposite side of glass or plastic with one side roughened, the transmittance varies due to the non-uniform thickness. There is a problem that unevenness occurs, and any of the above-described materials has a problem that the appearance quality as a timepiece dial is inferior.
[0009]
  The present invention has been made paying attention to the above-mentioned problems, and the object of the present invention is that design variations can be achieved, subtle shades can be achieved, and merchantability can be improved.With hologram displayElectronicclockIs to provide.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0035]
  Example 1
  FIG. 1 relates to the present invention.hologramFIG. 2 is a longitudinal sectional view of a wristwatch having a display panel structure (Example 1). FIG.clockFIG. 3 is a diagram illustrating the structure of the hologram display plate structure (Example 1) of FIG.clockIt is explanatory drawing of the incoming / outgoing light in the hologram display board structure of this.
[0036]
  Electronics according to the present inventionclockAs shown in FIG. 2, the hologram display plate structure includes a reflection plate 3 in which a hologram layer 2 is integrally laminated on a polyester layer or polyethylene terephthalate layer 1 which is a transparent resin layer, and is bonded to the hologram layer 2 of the reflection plate 3. Transparent or semi-transparent through layer 4

[0037]
  The hologram layer 2 has a virtual mirror surface 8 which is a reflection surface different from the upper and lower surfaces 2a and 2b. In this hologram layer 2, as shown in FIG. 3, the incident light 6a incident from the light source 6 does not coincide with the surface reflected light 6b / 6c (illustrated by dotted lines) reflected by the upper surface 2a / lower surface 2b of the hologram layer 2. The reflected light 6d that is tilted to reflect only light of a specific wavelength reaches the eyes of the observer 7.
[0038]
  That is, the incident light 6a is light having various wavelengths.YesColorless. The incident light 6a is reflected by the virtual mirror surface 8. Here, the virtual mirror surface 8 is tilted in a fixed direction and has a wavelength dependency that enhances only light of a specific wavelength by interference, and a high reflectance. Reflection angle dependency that reflects only the light of a specific wavelength when viewed from a specific direction by an observer, and the light transmission property of transmitting light of other wavelengths. ing.
[0039]
  For this reason, the reflected light 6d reflected by the virtual mirror surface 8 exhibits a certain predetermined color and reaches the eyes of the observer 7. Further, when the viewpoint of the observer 7 is rotated in the light source direction of FIG. 3, the reflected light 6d does not reach the eyes of the observer 7, so that the color of the specific wavelength cannot be seen. Therefore, design variations can be achieved and subtle shades can be achieved. In addition, since a transparent or translucent outer layer 5 is laminated on the hologram layer 2 of the reflecting plate 3 with an adhesive layer 4 interposed therebetween,sexThe moisture resistance can be improved, and the hologram layer 2 can be incorporated into the display plate structure.
[0040]

That is, a reflective plate 3 in which a polyester layer or a polyethylene terephthalate layer 1 which is a transparent resin layer and a hologram layer 2 are integrated is laminated on the substrate 14, and an adhesive layer 4 is formed on the hologram layer 2 of the reflective plate 3. A transparent or translucent outer layer 5 is laminated.
[0042]
  Further, holes 15, 16, and 17 are formed at the centers of the substrate 14, the reflector 3, and the outer layer 5, respectively, and the module 12 is provided with a double needle shaft 18. The needle shaft 18 passes through the holes 15, 16, and 17. An hour hand 20 is attached to the outer shaft 19 of the needle shaft 18, and a minute hand 22 is attached to the inner shaft 21. A windshield 24 </ b> A is attached to the front side, and a back cover 24 </ b> B is attached to the bottom side of the inner trunk 11 via a waterproof packing 23.

The observer 7 has his eyes in a certain direction to see the time on the clock. The time can be read by the hour hand 20 and the minute hand 22.
[0044]
  On the other hand, the incident light 6a incident on the reflector 3 from the outer layer 5 delivers the color of the light 6d having a specific wavelength reflected by the virtual mirror surface 8 in FIG. 3 to the observer 7, and the reflected light having a wavelength other than the specific wavelength is transmitted. The light 6e is transmitted through the hologram layer 2 and is absorbed by the solar cell (amorphous silicon layer) 13 to become light that contributes to power generation. Of course, the generated electric power is supplied to the module 12 via the substrate 14 to drive the needle shaft 18.
[0045]
  When the viewpoint of the observer 7 is rotated in the direction of the light source in FIG. 3 or when the clock is rotated while keeping the viewpoint unchanged, the reflected light 6d does not reach the eyes of the observer 7, so the color of the specific wavelength is can not see.
[0046]
  By such an action, the color of the normally dark purple solar cell 13 is hidden and reflected by the reflecting plate 3, that is, the reflected light 6d reflected by the virtual mirror surface 8 of the hologram layer 2 has a predetermined color. And reaches the eyes of the observer 7.

  As described above, according to the first embodiment, the hologram layer 2 has the virtual mirror surface 8 that is a reflection surface different from the upper and lower surfaces 2 a and 2 b, and is incident from the light source 6 by the virtual mirror surface 8. The incident light 6a is tilted so as not to coincide with the surface reflected lights 6b and 6c reflected by the upper surface 2a and the lower surface 2b of the hologram layer 2, and reflects only light of a specific wavelength. For this reason, the reflected light 6d reflected by the virtual mirror surface 8 has a predetermined color and reaches the eyes of the observer 7, and the color of the normally dark purple solar cell 13 is hidden.

  By such an action, the color of the EL cell 25 is hidden and reflected by the reflecting plate 3, that is, the reflected light 6d reflected by the virtual mirror surface 8 of the hologram layer 2 exhibits a certain predetermined color.
It reaches the eyes of the observer 7.
[0054]
  Further, by applying an AC voltage to the electrode of the EL cell 25, the EL cell 25 is caused to emit light. This light emission and the reflected light 6d reflected by the virtual mirror surface 8 of the hologram layer 2 can be combined to enable a delicate color tone.

For this reason, the reflected light 6d reflected by the virtual mirror surface 8 exhibits a predetermined color and reaches the eyes of the observer 7, and the color of the EL cell is hidden by such an action.
[0056]
  Further, when the EL cell is caused to emit light by applying an AC voltage to the electrode of the EL cell, the light emission and the reflected light 6d reflected by the virtual mirror surface 8 of the hologram layer 2 are combined to create a subtle Tint is possible.
