Description




BACKGROUND OF THE INVENTION




The present invention relates to a luminescent device and a watch with the luminescent device.




An Electro Luminescence element (hereinafter, which may be called “luminescent member”) is a plate-like luminescent member, from the whole surface of which luminescence are emitted by an applied voltage.




The EL luminescent member, recently, is disposed in various types of electronic apparatuses, e.g., a watch, an electronic pocket notebook and the like. Because the EL luminescent member does not generate heat and the amount of electric power consumed thereby is small, the EL luminescent member has been applied to such types of apparatuses widely.




An example of a conventional watch with an EL luminescent member will be explained briefly in the following.




In case of the conventional watch with the EL luminescent member, a mechanism for driving analog hands is provided in an inner space between a watch glass which is disposed in an upper part of a watch case and a back cover which is disposed in a lower part of the watch case, namely, in the inside of the watch case.




The analog hands mechanism comprises a shaft for hands which extends from the center of the analog hands mechanism upwardly. Hands which comprise a minute hand and an hour hand are connected with the shaft for hands. A dial and a plate-like EL luminescent member in a layered state are placed on the upper surface of the analog hands mechanism. The periphery of the dial and the plate-like EL luminescent member are pressed down by a pressing member, thereby the dial and EL luminescent member are fixed to the watch case.




The dial is made of a translucent film or a light-transmissive color film, on the upper surface of which marks, e.g., time indices or the like, are printed. The EL luminescent member emits light from the entirety of the surface thereof by an electric power or a voltage, for luminescence, which are supplied from a power source provided on a circuit board (an illustration of which is omitted) which is incorporated in the analog hands mechanism. Thereby, the EL luminescent member illuminates the whole dial and the whole hands of the analog hands mechanism, which are provided at an upper position to the EL luminescent member. Therefore, the present time can be read even at night or in the dark from the outside through the dial and the hands illuminated by the EL luminescent member.




According to the structure as described above, because the dial and the like are illuminated by the EL luminescent member, the dial must be made of a material through which light from the EL luminescent member can be transmitted. Therefore, a translucent film or a light-transmissive color film are generally used for the dial.




The entirety of the dial become light by the luminescence from the EL luminescent member to enable reading the time indices and the hands.




Conventionally, because the dial of a watch has a film on the surface thereof, which gives no metallic feeling, there are the problems of being uninteresting and no feeling of high quality.




SUMMARY OF THE INVENTION




The present invention is accomplished in consideration of the conventional problems as described above.




Therefore, an object of the present invention is to provide a luminescent device which is interesting and gives a feeling of high quality, and to provide a watch with such a luminescent device.




In order to accomplish the object of the invention, in accordance with one aspect of the present invention, the luminescent device comprises; a plate-like EL luminescent member, a layer for giving a feeling of metallic gloss by receiving illumination of light emitted from the surface of a plate-like EL luminescent member, which is disposed at least in a side of an upper surface and a lower surface, of the luminescent member, and which is one selected from a metallic layer and a metallic ink layer.




The luminescent member is, for example, one which uses an electro luminescence phenomenon. A pattern having a predetermined shape, time indices for indicating time, and marks which are formed at positions corresponding to those of the time indices are provided on the metallic layer.




Because the metallic layer is formed on the upper surface or the lower surface of the film member, on the luminescent member, a metallic feeling is given to the film member. Additionally, because the film member is light-transmissive, the film member transmits the light from the luminescent member which is disposed at a lower position of the film member, thereby the film member has a metallic lightness and become light.




In accordance with another aspect of the present invention, the luminescent device comprises a plate-like luminescent member, a light-transmissive film member which is disposed at an upper position of the plate-like luminescent member and is illuminated in whole by light from the luminescent member, and a metallic ink layer which is formed on the upper surface of the film member.




Design printed on the film member by using metallic ink is free. For instance, a lattice pattern, a hatching pattern or the like can be printed. Although the printed parts with metallic ink does not transmit light, since the non-printed parts transmit light, the pattern can be clearly observed by contrast of lightness and darkness.




According to the luminescent device as described above, a light-transmissive color film can be disposed at the upper position of the film member, thereby a color metallic feeling can be given.




The watch according to the invention comprises: a watch case comprising an analog hand mechanism having hands, in the inside thereof; a plate-like luminescent device which is provided in the watch case for illuminating the analog hand mechanism in the watch case; and a metallic layer or a metallic ink layer, which gives a feeling of metallic gloss by receiving illumination of light emitted from a surface of the luminescent device, which is disposed at least in a side of an upper surface and a lower surface of the luminescent device.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Embodiment 1




FIG.


1


and

FIG. 2

show a first embodiment in which the luminescent device according to the present invention is applied for a watch.




The watch, as shown in

FIG. 1

, comprises a watch case


1


which has a watch glass


2


provided in an upper side thereof and a back cover


3


provided in a lower side thereof, and an analog hand mechanism


4


which is disposed in the watch case


1


.




The analog hand mechanism


4


comprises a circuit board, a body


5


in which a battery and other parts are incorporated, a shafts for hands


6


which extend from the center of the body


5


upwardly, and hands


7


which include a minute hand and an hour hand and the like and which are connected with the shafts for hands


6


, respectively. The analog hand mechanism


4


also includes a projection


4




a


formed in its periphery.




On the upper surface of the body


5


of the analog hand mechanism


4


, a plate-like EL luminescent member


8


and a light-transmissive film member


9


which is made of a transparent material, are layered. A luminescent device A


1


comprises the plate-like EL luminescent member


8


and the light-transmissive film member


9


.




Through holes


8




a


and


9




a


are formed at each center of the EL luminescent member


8


and the film member


9


, wherein the shaft of the hands


6


pass through the through holes


8




a


and


9




a


and extend upwardly. The pressing member


10


includes a projection


10




a


provided on an upper side thereof, and a projection


10




b


provided on a lower side thereof.




A pressing member


10


is a member for pressing the peripheries of the film member


9


and the EL luminescent member


8


to fix these members on the body


5


. A sealing member


11


is provided between the upper surface of the back cover


3


and the lower surface of the watch case


1


.




In the watch having such a structure, when a predetermined voltage is applied from a power source (not shown in Figures) which is provided on a circuit board of the analog hand mechanism


4


, the entirety of the surface of the EL luminescent member


8


emits light to illuminate the entirety of the film member


9


which is provided at an upper position of the EL luminescent member


8


.




The film member


9


constitutes a dial and has a light-transmissive property. A metallic layer (refer to

FIGS. 2A

to


2


E) is formed on an upper surface and/or a lower surface of the film member


9


by deposition of a metal.





FIGS. 2A

to


2


E show examples of structures of luminescent devices A


1


, that is, of layered structures of the film member


9


and the EL luminescent member


8


.




Examples of the structures will be explained in detail, as follows.




In case of the structure of the luminescent device A


1


as shown in

FIG. 2A

, a metallic layer


19


is deposited on the upper surface of the film member


9


. Aluminum, silver, gold or the like may be used as a metal for forming the metallic layer


19


. In case of this embodiment, a metal is optionally selected from the group of metal, and thereafter the metallic layer


19


is formed on the upper surface of the film member


9


by deposition of the metal selected. Thereby, gloss peculiar to the metal of the metallic layer


19


is given to the upper surface of the film member


9


. Therefore, even while the surface of the EL luminescent member


8


does not illuminate, the film member


9


shines with metallic gloss by the function of the metallic layer


19


which is formed on the film member


9


, so that the film member


9


can be observed from the outside with the same sense as a metallic dial.




Time indices


21


are printed at positions to be marked, on the upper surface of the film member


9


by offset printing, silk screen printing or the like.




In this

FIG. 2A

, when the EL luminescent member


8


emits light from the entirety of the surface thereof, the upper surface of the film member


9


shines by the effect of the metallic layer


19


which is formed on the upper surface of the film member


9


, and thereby the upper surface or the time indices can be read clearly from the outside.




The metallic layer


19


may be formed on the lower surface of the film member


9


with a difference from the embodiment. That is, the metallic layer


19


may be formed also between the lower surface of the film member


9


and the upper surface of the luminescent member


8


.




In case of the structure of the luminescent device A


1


, as shown in

FIG. 2B

, in addition to the layered structure shown in

FIG. 2A

, a color film


22


is layered as the top layer of the structure on the upper surface of the metallic layer


19


which is formed on the upper surface of the film member


9


. The color film


22


is made of a light-transmissive material, and is colored with suitable color.




Because the color film


22


is layered on the upper surface of the metallic layer


19


on the upper surface of the film member


9


as the top layer of the layered structure, the color of the color film


22


is added to the metallic gloss of the metallic layer


19


which is formed on the upper surface of the film member


9


. Therefore, the time indices or the like on the upper surface of the film member


9


is observed with a color metallic feeling because of a state of a mixture of the metallic gloss and the color.




In case of the structure of the luminescent device A


1


, as shown in

FIG. 2C

, a metallic layer


23


is formed on the lower surface of the light-transmissive color film


22


by deposition, without the film member


9


, and the color film


22


is layered so that the metallic layer


23


faces to the EL luminescent member


8


.




That is, in case of the structure shown in

FIG. 2C

, the metallic layer


23


is formed by deposition between the light-transmissive color film


22


and the EL luminescent member


8


without the film member


9


.




In spite of a simple structure which does not include the film member


9


, according to such a structure, it is possible not only to observe the time indices or the like with the same color metallic feeling as the structure shown in

FIG. 2B

but also to make the whole luminescent device, that is, the whole structure comprising the color film


22


, the EL luminescent member


8


and the metallic layer


23


, thin.




In case of the structure of the luminescent device A


1


shown in

FIG. 2D

, the light-transmissive film member


9


which has the metallic layer


19


deposited on the upper surface thereof is layered on the upper surface of the EL luminescent member


8


. A transparent film


24


is layered on the upper surface of the film member


9


. A light-transmissive color printed layer


25


is printed on a lower surface of the transparent film


24


by using a color ink, and the transparent film


24


is layered on the film member


9


so that the color printed layer


25


face to the film member


9


. Such a structure enables observation with a color metallic feeling. In this case, the color printed layer


25


may be provided on the upper surface of the transparent film


24


.




In case of the structure of the luminescent device A


1


shown in

FIG. 2E

, the color printed layer


25


is provided on the upper surface of the light-transmissive film member


9


which has the metallic layer


19


deposited on the surface thereof. Thus, a color metallic feeling is given by the color printed layer


25


.




In each of the examples shown in

FIGS. 2A

to


2


E, if an EL luminescent member which emits white light or light of other color is used as an EL luminescent member


8


for emitting light to the whole surface of the film member


9


, it is possible to emit the light with the desired color through the whole surface of the film member


9


.




Next, an example of manufacturing method of the luminescent device A


1


will be illustrated with reference to

FIGS. 2F

to


2


I, as follows.




First, a film material


9


A which is formed in roll, as shown in

FIG. 2F

, is cut in a predetermined size, as shown in FIG.


2


G. The metallic layer


19


is formed by deposition on the whole upper surface of the cut film member


9


. The deposition is half-deposition by which the metallic layer


19


is formed on the whole upper surface of the film member


9


so that the metallic layer


19


is formed extremely thin so as to have a translucent property.




Next, as shown in

FIG. 2H

, the time indices


21


for showing time of watches, outline parts


21


A which show the circle outlines of the watches, and positioning marks


21

21


B are printed by a printing method, e.g., offset printing, silk screen printing or the like.




Next, as shown in

FIG. 2I

, each outline part


21


A which is printed on the film member


9


is stamped out by a press machine, thereby the round film members


9


on which the time indices


21


is printed is cut out.
