DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display member having a light emitting function used for a timepiece such as a wristwatch, a timepiece having the display member, and an electronic apparatus.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 15, a pointer-type wristwatch is provided with a timepiece module 1 having an analog movement 2 and a timepiece dial 3 provided on an upper surface of the timepiece module 1. I have. In this case, a shaft insertion hole 3 a is provided in the center of the timepiece dial 3. The pointer shaft 2a of the analog movement 2 is inserted into the shaft insertion hole 3a and protrudes upward. A pointer 4 such as an hour hand or a minute hand is attached to an upper end of the protruded pointer shaft 2a. Thus, in this wristwatch, the pointer 4
Is configured to indicate the time by moving the hands above the timepiece dial 3.

In such a wristwatch, the timepiece dial 3 is configured as shown in FIG. 16 so that the time can be known even in a dark place. That is, the timepiece dial 3 includes a planar light emitting type light emitting member 5 such as an EL element (electroluminescence element), and a thin film metal in which a large number of fine through holes 7 are formed on the upper surface of the light emitting member 5. Layer 6
Is provided on the outer peripheral portion on the upper surface of the metal layer 6.
(See FIGS. 17 and 18) and the metal layer 6
A decorative portion 9 such as a display mark is provided at a predetermined position on the upper surface of the device by printing.

In this case, the through hole 7 of the metal layer 6 is a fine hole, but it is difficult to form the through hole 7 with a diameter smaller than the thickness of the metal layer 6. Therefore, the through hole 7 is slightly larger than the thickness of the metal layer 6. It is formed with a hole diameter. Further, in the metal layer 6, since the decorative portion 9 cannot be provided by printing on the upper side of the through hole 7, the through hole 7 is not formed in a region where the decorative portion 9 is provided, and the through hole 7 is formed. The decorative portion 9 is provided in an area that is not provided.

In the timepiece dial 3 of this wristwatch, FIG.
As shown in FIG. 7, the time can be known by the hands 4 in a bright place, and the metal layer 6 can obtain a metal-like decorative effect and the decorative portion 9 can obtain the decorative effect. In a dark place, as shown in FIG. 18, when the light emitting member 5 emits light, the light passes through a large number of through holes 7 formed in the metal layer 6 and illuminates the upper surface side of the metal layer 6. You can know the time even in dark places.

[0006]

However, in such a timepiece dial 3 for a wristwatch, the decorative portion 9 is provided without forming the through hole 7 in the area of the metal layer 6 where the decorative portion 9 is provided. Therefore, in a bright place, as shown in FIG. 17, the decorative part 9 such as a display mark can be visually recognized, but in a dark place, as shown in FIG. Since the region of the metal layer 6 blocks light from the light emitting member 5, the entire region corresponding to the decorative portion 9 becomes dark, and accordingly, the entire illumination by the light emitting member 5 becomes dark, and the decorative portion 9 becomes visible. Not only that, there is a drawback that the hands 4 become difficult to see, making it difficult to visually recognize the time.

An object of the present invention is to make it possible to illuminate brightly with a light emitting member even in a dark place, and to be able to satisfactorily know the time.

[0008]

The present invention has the following components to solve the above-mentioned problems. In addition, to each component, reference numerals and the like of the drawings attached to each element described in the section of each embodiment described later are added together with parentheses. As shown in FIGS. 1 to 4, the invention according to claim 1 includes a light emitting member (20) and a metal layer disposed on the upper surface of the light emitting member and formed with a large number of fine through holes (25). 21), a light-transmitting sheet (22) provided on the upper surface of the metal layer, and a non-light-transmitting decorative portion (24) provided on at least one of the upper and lower surfaces of the light-transmitting sheet. A display member (a timepiece dial 13) comprising: According to the present invention, in addition to the time and the like being well known in a bright place, the metal layer can be seen through the light transmitting sheet, so that a metal-like decorative effect can be obtained and the decorative effect by the decorative portion can be obtained. Also, in a dark place, light from the light-emitting member passes through the light-transmitting sheet through a number of fine through holes in the metal layer, and when illuminating the upper surface side, light is blocked at a non-light-transmitting decorative portion. However, since a large number of through holes are also formed in the metal layer corresponding to the decorative portion, the entire region corresponding to the decorative portion does not become dark as in the conventional example, and the upper surface side of the light transmitting sheet is not darkened. Can be brightly illuminated, so that the time and the like can be well known even in a dark place, and the decorative part can be visually recognized by its outline even in a dark place.

According to a second aspect of the present invention, as shown in FIGS. 8 to 10, a light emitting member (20) and a large number of fine through holes (25) disposed on the upper surface of the light emitting member are formed. Metal layer (21), a light transmitting sheet (22) provided on the upper surface of the metal layer, and a light transmitting decorative portion provided on at least one of the upper and lower surfaces of the light transmitting sheet (28) A display member (the timepiece dial 13). According to the invention,
In a bright place, it is possible to know the time and the like as well as in the invention according to claim 1, and to obtain a metallic decoration effect and a decoration effect by the decorative portion. When light passes through the light-transmitting sheet through a large number of fine through holes in the layer and illuminates the upper surface side, light also passes through the light-transmitting decorative portion. It is possible to illuminate evenly and brightly, so that the time and the like can be well known even in a dark place, and the decorative part cannot be seen in a dark place, but the decorative part can be seen in a bright place. And different decoration effects can be obtained in dark places.

[0010] In this case, the invention described in claim 3 is based on FIG.
As shown in FIG. 1 and FIG. 12, since the entire light transmitting sheet (30) is colored, the metal layer (21) is colored according to the color of the light transmitting sheet (30). Therefore, an expression of a color-added metal tone can be obtained. Further, according to the invention described in claim 4, as shown in FIGS. 13 and 14, the light transmitting sheet (32) is colored in a different color for each part, so that the metal layer (21) is provided for each part. Since the colors are added with different colors, a metal tone expression partially added with different colors is obtained. Further, according to the fifth aspect of the present invention, as shown in FIGS. 2 and 8, the through hole (25) of the metal layer (21) is substantially etched in the vertical direction by etching from both upper and lower surfaces of the metal layer. Since the through holes are formed with the same size, the diameter of the through holes can be made smaller than the thickness of the metal layer, whereby the through holes can be made inconspicuous.

According to a sixth aspect of the present invention, as shown in FIG. 6, the through hole (26) of the metal layer (21) is located on the lower surface side by etching from both upper and lower surfaces of the metal layer. Since the cross-sectional area of the hole (26b) formed is larger than the cross-sectional area of the hole (26a) positioned on the upper surface side, the hole positioned on the upper surface side of the through hole can be further reduced. As a result, the through hole can be made less noticeable when viewed from the upper surface side, and the light from the light emitting member can be sufficiently captured by the hole portion located on the lower surface side, thereby transmitting the through hole. Since the light amount can be secured, even if the hole located on the top side is small,
A sufficient illuminance can be obtained. In particular, as shown in FIG. 7, the invention according to claim 7 is a hole (27b) located on the lower surface side of the through hole (27) formed in the metal layer (21).
Is formed in a size corresponding to a plurality of holes (27a) located on the upper surface side, so that the light transmission amount can be obtained only by changing the number of holes on the upper surface side corresponding to the holes on the lower surface side. Can be changed, and thereby the illuminance can be changed.

According to an eighth aspect of the present invention, as shown in FIG. 1, the display member (timepiece dial 13) according to the first or second aspect is arranged in a timepiece case (10). A timepiece wherein a timepiece glass (11) is arranged at an upper position of the display member arranged in the timepiece case. According to the present invention, even if the display member is arranged in the watch case, the display member can be seen through the watch glass arranged at the upper position of the display member, so that the display member can know the time even in a dark place. In addition, various decorative effects can be obtained by the display member. The invention according to claim 9 is the invention according to claim 1 or 2
An electronic device characterized in that the display member described in (1) is disposed in a device case. According to the present invention, since the display member is arranged in the device case, the time and the like can be known even in a dark place by the display member, and various decorative effects can be obtained by the display member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [First Embodiment] A first embodiment in which the present invention is applied to a wristwatch will be described below with reference to FIGS. FIG. 1 is an enlarged sectional view of a main part showing an internal structure of a wristwatch. This watch includes a watch case 10. In the upper part of this watch case 10,
A watch glass 11 is mounted via a packing 12, and a watch dial 13 and a watch module 14 are housed inside a watch case 10 in an overlapping manner. A back cover 15 is attached to a lower portion of the watch case 10 via a prevention ring 16.

The clock module 14 has at least the analog movement 1 of the analog function and the digital function.
The analog movement 17 has an analog function, and the pointer shaft 18 of the analog movement 17 projects upward through a shaft insertion hole 13a provided in the center of the timepiece dial 13; Hands 19 such as a minute hand and a second hand are attached, and these hands 19 are configured to move above the timepiece dial 13. As shown in FIG. 2, the timepiece dial 13 includes a light-emitting member 20, a light-transmitting metal layer 21 provided on the upper surface of the light-emitting member 20, and a light-transmitting metal layer 21 provided on the upper surface of the metal layer 21. A transmissive sheet 22, a time character 23 (see FIGS. 3 and 4) provided on the outer peripheral portion of the upper surface of the light transmissive sheet 22, and a non-light transmissive material provided at a predetermined position on the upper surface of the light transmissive sheet 22. The watch module 14 includes a decorative portion 24, which is formed in a flat plate shape and is disposed on the upper surface of the timepiece module 14.

The light emitting member 20 has a structure in which a large number of light emitting diodes are arranged on the lower surface of an EL element or a diffusion plate;
Alternatively, it is a planar light-emitting body such as a light-emitting diode having a structure in which a light-emitting diode is arranged on a side surface of a light guide plate, and is configured so that light emitted at the time of lighting is substantially uniformly emitted to the upper surface side.
The metal layer 21 is made of a metal such as stainless steel, and is a thin metal foil having a thickness of about 0.1 mm. As shown in FIG. 2, a large number of fine through holes 25 are formed in the metal layer 21. These through-holes 25 are provided with mask portions on both upper and lower surfaces of a thin metal foil, and the metal foil is etched from both upper and lower surfaces through the mask portions, so that the hole diameter is smaller than the thickness of the metal layer 21 and the through holes are vertically oriented. The light emitting member 20 is formed so as to transmit light from the light emitting member 20.

The light transmitting sheet 22 is a transparent or translucent sheet made of a synthetic resin, is disposed on the upper surface of the metal layer 21 so as to cover each through hole 25, and transmits light transmitted through each through hole 25. It is configured as follows. The time character 23 is 1
It is a time mark representing 2:00, 3:00, 6:00, 9:00, etc.
It is formed of a non-light-transmitting material such as a metal or a synthetic resin. The decorative portion 24 is a display mark for a clock function, a display mode state, or the like, and is formed by printing a non-light-transmitting material at a predetermined location on the upper surface of the light-transmitting sheet 22, for example, at 12:00 as shown in FIGS. , 6 o'clock and 9 o'clock.

According to such a timepiece dial 13, in a bright place, external light is reflected by a surface other than the through-hole 25 of the metal layer 21, so that as shown in FIG. In addition, since the hole diameter of the through hole 25 of the metal layer 21 is formed smaller than the thickness of the metal layer 21, even if a large number of through holes 25 are formed in the metal layer 21,
Since the through holes 25 are inconspicuous and the metal layer 21 can be visually recognized through the light transmitting sheet 22, a metal-like decorative effect can be obtained, and the decorative effect by the decorative portion 24 can be obtained.

In a dark place, when the light emitting member 20 emits light, the light passes through a large number of through holes 25 of the metal layer 21, and the transmitted light passes through the light transmitting sheet 22 so that the upper surface side is formed. When illuminating, light is shielded at a portion of the non-light-transmitting decorative portion 24, but since a large number of through holes 25 are formed in the metal layer 21 at a portion corresponding to the decorative portion 24,
As in the conventional example, the entire area corresponding to the decorative portion 9 does not become dark, and as shown in FIG. 4, it is possible to illuminate almost the entire upper surface side of the light transmitting sheet 22 with light from the light emitting member 20. Thus, the time can be well known even in a dark place, and the decorative part 24 can be visually recognized by its outline even in a dark place.

Further, according to the wristwatch using the timepiece dial 13, even if the timepiece dial 13 is arranged in the watch case 1, the timepiece 13 passes through the timepiece glass 2 arranged above the timepiece dial 13. Since the timepiece dial 13 can be seen, even if a large number of through holes 25 are formed in the metal layer 21 of the timepiece dial 13, the through hole 25 is inconspicuous because the hole diameter is small. The metal layer 21 of the plate 13 provides a metallic decoration effect and the decoration part 24 provides a decoration effect, and the time can be known even in a dark place.

In the first embodiment, the decorative portion 24 is provided on the upper surface of the light transmitting sheet 22, but the present invention is not limited to this.
For example, as shown in FIG. 5, a structure in which a decorative portion 24 is provided at a predetermined position on the lower surface of the light transmitting sheet 22 may be used. With such a structure, similarly to the first embodiment, when light from the light emitting member 20 passes through the light transmitting sheet 22 through the many through holes 25 of the metal layer 21, the light is shielded by the non-light transmitting decorative portion 24. However, since the light from the light emitting member 20 can illuminate almost the entire upper surface side of the light transmitting sheet 22 brightly, the time can be known and the decoration part 24 can be visually recognized in a dark place or a bright place. be able to.

That is, the through-hole 26 of the modified example shown in FIG. 6 is formed by providing different mask portions on the upper and lower surfaces of the metal layer 21 and etching the metal layer 21 from both the upper and lower surfaces via the mask portions. The hole diameter of the hole 26a located on the upper surface side of the metal layer 21 is formed smaller than the hole diameter of the hole 26b located on the lower surface side of the metal layer 21. In this case, the shape of the hole 26a on the upper surface and the shape of the hole 26b on the lower surface may be the same or different.

According to the metal layer 21 in which the through holes 26 are formed, the diameter of the hole 26a located on the upper surface side can be made smaller than that of the first embodiment. 26 can be made more inconspicuous, and since the hole diameter of the hole 26b located on the lower surface side is large, light from the light emitting member 20 can be sufficiently taken in by the hole 26b on the lower surface side. Accordingly, a sufficient amount of illuminance can be obtained even if the hole 26a on the upper surface is small, so that illumination above the light transmitting sheet 22 can be illuminated.

The through-hole 27 of the modification shown in FIG.
Are provided with mask portions different from each other on the upper and lower surfaces of the metal layer 21, and by etching the metal layer 21 from both the upper and lower surfaces via the mask portions, the hole portions 27b located on the lower surface side of the metal layer 21 are formed. Hole 2 located on the upper surface side of 21
7a is formed in a size corresponding to a plurality (three in the figure). According to the metal layer 21 having such a through-hole 27 formed therein, the same effect as the metal layer 21 having the above-described through-hole 26 is obtained, and in particular, the upper surface side corresponding to the hole 27b on the lower surface side. By simply changing the number of the holes 27a, the amount of transmitted light can be changed, whereby the illuminance can be changed.
