Description

  The present invention relates to a timepiece with a wireless function, and more particularly, to a timepiece having an antenna capable of receiving a predetermined radio wave and a conductive housing for housing the antenna.

Conventionally, a watch having a wireless function such as a personal computer communication function, a mobile phone function or a non-contact IC card function is already known.
As such a wireless function watch, a radio timepiece having a wireless function for receiving a long-wave standard radio wave (carrier wave) including time information and correcting the time based on the time information is also widely known.

These wireless function watches need to have an antenna for receiving a predetermined radio wave, as with other communication devices.
For this reason, in view of the function of receiving radio waves, that is, reception sensitivity, it is conceivable that the housing, which is a housing for housing the antenna that receives radio waves, is made of a nonconductive material such as synthetic resin.

However, since these wireless function watches are watches, they are different from other communication devices and require a beautiful appearance and a high-class feeling as an ornament or an accessory.
For this reason, it is required to employ a conductive material, that is, a metal material, instead of a non-conductive material such as a synthetic resin for a housing that is a housing for housing an antenna that receives radio waves.

  This is because a housing such as a synthetic resin gives the user an inexpensive appearance and a feeling of wearing due to its texture, color tone, or light weight, whereas a metal housing has a high-class feeling. This is to give the user a certain appearance and wearing feeling.

This demand for a metal housing is particularly significant in a wristwatch as an accessory carried by a user.
However, when the antenna is housed in a conductive housing, i.e., a metal housing, the magnetic flux generated in the vicinity of the antenna is absorbed by the metal housing, which is a conductive material, and the resonance phenomenon is hindered. The reception function for the antenna to receive standard radio waves will be significantly reduced.

For this reason, various proposals for improving reception sensitivity have been made.
For example, Patent Document 1 (Japanese Patent Laid-Open No. 2002-341057) discloses a radio timepiece including a metal housing that is a metal casing, particularly a radio timepiece.

That is, as shown in FIG. 31, the radio timepiece 100 includes a housing 102.
In the present specification, the “vertical direction” means the vertical direction in FIG. 31 or 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 means the left-right direction in FIG. 31, and the planar direction overlaps with the longitudinal direction of the band or the width direction of the band. In some cases.

  The housing 102 includes a watch case 104 constituting a metal frame, a metal back cover 106 which is mounted in a sealed state so as to cover a lower surface opening of the watch case 104, and an upper surface opening of the watch case. And a windshield (glass) 108 mounted in a sealed state.

  In the housing 102, a movement 110 constituting a timepiece driving unit and a solar cell 112 disposed on the upper surface of the movement 110 for driving the movement by an electromotive force of light are provided.

  Further, on the upper surface of the solar cell 112, there is provided a dial plate 114 having a translucent function that transmits external light having a wavelength contributing to power generation of the solar cell 112 at least enough to drive the movement 110.

Further, an antenna 116 for receiving standard radio waves is attached below the side of the movement 110.
Although not shown, a minute hand and an hour hand are arranged on a needle shaft that protrudes from the movement 110 and penetrates the solar cell 112 and the dial plate 114. These minute hand and hour hand are positioned between the dial plate 114 and the windshield 108 to display the time.

  Further, the watch case 104 includes two sets of band attaching portions 118 projecting outward, and the band attaching portions 118 are disposed at a predetermined interval so as to face each other. The leg part 120 extended from 104 is provided.

A wristwatch band (not shown) is connected between each of the leg portions 120.
By the way, in the radio timepiece 100 adopting such a metal exterior, when the antenna 116 receives radio waves, the eddy current along the circumferential direction of the annular wall is induced in the metal timepiece case 104. Will flow as.

This eddy current cancels out radio waves from the outside of the housing 102, and the reception sensitivity of the antenna 116 is extremely lowered.
In order to avoid such a phenomenon, in the radio timepiece 100 of Patent Document 1, the annular wall of the timepiece case 104 is provided with a slit 122 that divides the timepiece case 104 in the circumferential direction.

  That is, as shown in FIG. 31, the watch case 104 is completely divided in the vertical direction by the slit 122, and as a result, the watch case 104 has a substantially C-shaped frame shape by the slit 122. It has become.

  In FIG. 31, the slit 122 is omitted for clarity and is not shown, but the slit 122 is embedded with an insulating member made of non-conductive synthetic resin. ing.

That is, the insulating member is configured to maintain the waterproofness and strength of the watch case 104.
Therefore, in the radio timepiece 100 having the slit 122, since the eddy current does not flow along the circumferential direction of the annular wall of the timepiece case 104 when the antenna 116 receives a radio wave, a conductive metal timepiece case. Even when 104 is adopted, reception of the antenna 116 is ensured.
JP 2002-341057 A

  However, in the radio timepiece 100 of Patent Document 1, since a slit 122 is formed in a part of the watch case 104 and an insulating member made of a synthetic resin is embedded in the slit 122, the appearance is not good. Compared to a watch case made entirely of metal, it is not as high-quality and the strength of the insulating member is inevitably weakened, resulting in waterproofness, impact resistance, wear resistance, and chemical resistance. Will also be inferior.

  In the radio timepiece 100 of Patent Document 1, a slit 122 is formed in a part of the timepiece case 104 to improve the reception sensitivity of the antenna 116, but the radio timepiece 100 is placed at the time of reception. Depending on the location, the surrounding environment, or even the posture of the watch, the antenna could often not be received.

  Therefore, even in the radio timepiece 100 having the slit 122 as in Patent Document 1, it is difficult to say that the reception sensitivity of the antenna 116 still has sufficient reception sensitivity.

  In view of such a current situation, the present invention provides a watch with a wireless function that has a good appearance, has a high-class feeling, is excellent in strength, and can reliably receive radio waves by an antenna housed inside. The purpose is to do.

The present invention was invented in order to achieve the above-described problems and objects in the prior art, and the wireless function watch of the present invention is
A wireless function watch,
A housing;
An antenna housed in the housing for receiving radio waves from the outside;
A conductive annular member disposed within the housing;
And at least one slit formed in the annular member and dividing the annular member in the circumferential direction.

  With this configuration, a slit that divides the annular member in the circumferential direction is formed in the conductive annular member housed in the watch case, so that an eddy current flows along the annular member by the slit. Is interrupted, and the generation of eddy currents is prevented.

As a result, a decrease in the reception sensitivity of the antenna due to the eddy current flowing in the annular member is prevented, and the reception sensitivity of the antenna is improved.
Further, since the annular member is disposed in a housing sealed from the outside, even when a slit is formed in the annular member, the waterproofness of the housing itself does not deteriorate.

  The housing including the watch case in the present invention may be conductive such as metal or non-conductive such as synthetic resin. Alternatively, conductive parts and non-conductive parts may be mixed in the parts constituting the housing. A housing is understood to be a member that is at least partially conductive or at least partially non-conductive. Regardless of conductivity or non-conductivity, if a slit is provided in the conductive annular member disposed in the housing, a decrease in antenna reception sensitivity due to the eddy current of the annular member is avoided.

Further, a slit may be formed in a component constituting the housing in the present invention, for example, a watch case. Or the slit of a timepiece case may be excluded and a slit may be formed only in an annular member.

  In the present invention, the conductive member refers to “the material of the member itself is a conductive member” or “the member is covered with a conductive coating”. In the latter case, the material of the member itself may be a non-conductive material, a conductive material, or a combination of a non-conductive material and a conductive material.

On the contrary, the non-conductive member means “one whose material itself is a non-conductive member” or “one whose member is covered with a non-conductive coating”. In the latter case, the material of the member itself may be a non-conductive material, a conductive material, or a combination of a non-conductive material and a conductive material.

As the conductive material constituting the annular member, for example, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof can be employed . Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like may be employed.

The wireless function watch of the present invention is characterized in that the slit is arranged in the vicinity of the upper part of the antenna.
By arranging the slit in the vicinity of the upper part of the antenna in this manner, there is no conductive annular member that prevents radio wave reception above the antenna, so that the reception sensitivity of the antenna is improved.

  The wireless function watch of the present invention is characterized in that the slit is composed of two slits disposed in the vicinity of the upper part of the antenna so as to face both open ends of the antenna.

  By configuring in this way, there is no conductive annular member that prevents reception of radio waves by two slits in the portion facing the open both ends of the antenna. The reception sensitivity of the antenna is improved.

  The wireless function watch of the present invention is characterized in that the slit is composed of a slit disposed in the vicinity of the upper part of the antenna so as to face at least one open end of the antenna.

With this configuration, there is no conductive annular member that prevents reception of radio waves due to the slit in the portion facing the open end of at least one of the antenna. Is received at one open end of the antenna, and the reception sensitivity of the antenna is improved.

In addition, the wireless function watch of the present invention includes an insulating member disposed in a slit of the annular member.
With this configuration, the conductive annular member housed in the watch case is formed with a slit that divides the annular member in the circumferential direction, and the insulating member is disposed in the slit. Therefore, the flow of eddy current along the annular member is interrupted, and the generation of eddy current is prevented.

As a result, a decrease in the reception sensitivity of the antenna due to the eddy current flowing in the annular member is prevented, and the reception sensitivity of the antenna is improved.
Furthermore, since the insulating member is disposed in a housing sealed from the outside, even when the insulating member is disposed, the impact resistance, wear resistance, and chemical resistance of the housing itself do not deteriorate.

Moreover, since the insulating member is disposed in the slit as described above, the strength of the annular member is also maintained.
The insulating member may be a member made of a nonconductive material or a member in which a nonconductive film is coated on a conductive material. As the non-conductive material, for example, synthetic resin, rubber, or ceramic can be employed . As the conductive material, the material of the annular member described above can be employed .

As the non-conductive film coated on the conductive material, that is, the insulating film, for example, an insulating film made of an organic material such as an acrylic material, a urethane material, or a cellulose material can be employed . Moreover, as this insulating film, for example, a chromium compound-based film containing a chromium compound or an aluminum oxide-based film containing an aluminum oxide compound can be employed .

As the chromium compound-based coating, a chromium oxide-based coating including a chromium oxide compound, a chromium nitride-based coating including a chromium nitride compound, or a chromium carbide-based coating including a chromium carbide compound can be employed .

An insulating film may be employed as the insulating region disposed between the two.

Further, instead of the insulating coating, an insulating sheet made of synthetic resin or rubber may be attached.
The insulating member is preferably fixed to the annular member so as not to be pulled out carelessly. As the fixing means, for example, mechanical engaging means such as fitting, press-fitting, joining, insert molding, etc. can be employed . As the bonding layer for bonding the insulating member and the annular member, for example, an adhesive, a pressure-sensitive adhesive, or a double-sided tape is used. These bonding layers are preferably non-conductive insulating layers.

In the wireless function watch of the present invention, the insulating member is a non-conductive synthetic resin.
By configuring the insulating member from a non-conductive synthetic resin in this way, the annular member can be reliably insulated at the slit portion, and the insulating member that matches the size and shape of the slit can be integrally molded, for example. Etc. can be easily manufactured.

The wireless function watch of the present invention is characterized in that the color tone of the viewing surface of the insulating member is the same color tone as the color tone of the viewing surface of the annular member.
In this way, by configuring the color tone of the viewing surface of the insulating member to be the same color tone as the viewing surface of the annular member, the insulating member becomes less visible and the aesthetic appearance of the annular member and the aesthetic appearance of the watch itself are improved. It will be.

Here, the “viewing surface” refers to a region of the outer surface that is visually recognized by an observer.
In addition, here, “same color tone” means that the color tone of the annular member and the insulating member are both within the range where they can be recognized as the same color tone, and the appearance of the color tone such as the shade of the color tone or light and dark. The above texture is not limited to perfect match. For example, a deep gold color, a light gold color, a light gold color, or a dark gold color are all assumed to be the same color tone of gold here.

For example, even if the annular member has a bright golden color tone and the insulating member has a dark golden color tone , if the viewing surface of the annular member and the insulating member exhibits the same color tone of gold, the insulating member is less likely to be visually recognized. The beauty of the watch and the watch itself are improved.

  Further, when the annular member is a facing ring, the color of the viewing surface of the facing ring and the insulating member is the color of the material of the facing ring and the insulating member itself. May be used. Examples of such a film include a paint film, a printed film, and a dry plating film.

The outer surface of the annular member and the insulating member other than the viewing surface may have the same color tone, and for example, all outer surfaces of the annular member and the insulating member may have the same color tone.
In addition, the wireless function watch of the present invention is characterized in that the color tone of the viewing surface of the insulating member has a metal appearance that is the same color tone as the metal appearance that is the color tone of the viewing surface of the annular member.

Thus, in particular, the insulating member, if Teisure similar metal appearance and annular member made of a conductive material, together with the insulating member is difficult to be visually recognized, is given luxury to the annular member.
In order to obtain a metal appearance similar to that of the annular member made of a conductive material, for example, the insulating member may be coated with a paint film by metallic coating having the same color as that of the annular member. As this metallic paint film, for example, a paint film mixed with a metallic pigment can be employed .

For example, in order to obtain a stainless steel color, a coating film containing a stainless pigment containing iron, chromium, nickel, molybdenum, or the like as a component is coated.
For example, in order to obtain a gold color, a coating film containing a bronze pigment containing copper, zinc, iron or the like as a component is coated.

Alternatively, for example, in order to obtain a silver color, a coating film containing an aluminum pigment containing aluminum or a nickel pigment containing nickel is coated.
In addition to these, various pigments such as pearl pigments, graphite pigments, and phthaloshanine flakes may be employed.

The process for coating the insulating member is as follows.
First, a base coating film is coated on the outer surface of the insulating member. Next, a metallic paint film is coated on the base paint film. Further, a clear coat, which is a transparent or translucent synthetic resin layer, is coated on the metallic paint film. By this clear coat, even when a metal is contained in the metallic coating film, the outermost surface of the coated insulating member maintains non-conductivity.

  In order to ensure non-conductivity of not only metallic coating film but also such single coating film or lamination, insulating top coating film such as clear coat may be adopted as the outermost layer. preferable.

Examples of such insulating coating films include polyurethane resin paints, fluorine resin paints in which fluorine is mixed in polymer molecules forming the resin, vinyl chloride sol paints in which polyvinyl chloride resin is dispersed in a plasticizer, and oil-free polyesters.

Since no induced current is generated between the watch case 14 and the watch case 14, radio waves are received by one open end portion 26a of the antenna 26, and the reception sensitivity of the antenna 26 is improved.

In this case, the insulating region 58 can be composed of an insulating member disposed between the dial ring 36 and the watch case 14.

FIG. 13 is a partially enlarged perspective view similar to FIG. 3 of the wireless function watch 10 of another embodiment of the present invention, and is a partially enlarged perspective view illustrating a state in which the insulating member 74 is mounted in the slit 56.

  The wireless function watch 10 of this embodiment has basically the same configuration as the wireless function watch 10 shown in FIGS. 1 to 3, and the same reference numerals are given to the same components. Detailed description thereof will be omitted.

The wireless function watch 10 of this embodiment includes an insulating member 74 disposed in the slit 56 of the turn ring 36 that is an annular member.
That is, as shown in FIG. 13, the insulating member 74 has a cross section substantially the same shape as the cross section of the dial ring 36, and can be mounted in the slit 56.

  With this configuration, a slit 56 for dividing the dial ring 36 in the circumferential direction is formed in the conductive dial ring 36 accommodated in the watch case 14, and the insulating member 74 is disposed in the slit 56. Therefore, the insulating member 74 divides the flow of the eddy current along the turn ring 36 and prevents the generation of the eddy current.

As a result, a decrease in the reception sensitivity of the antenna 26 due to the eddy current flowing in the annular member is prevented, and the reception sensitivity of the antenna 26 is improved.
Further, since the insulating member 74 is arranged in the slit 56 as described above, the strength of the dial ring 36 is also maintained.

  Further, since the cross section of the insulating member 74 has substantially the same shape as the cross section of the facing ring 36, the viewing surface of the insulating member 74 forms substantially the same plane as the viewing surface of the facing ring 36. .

Therefore, since the viewing surface of the insulating member 74 is integrally viewed with the turn-around ring 36, the beauty and luxury of the ring turn-around ring 36 are improved, and the beauty of the watch itself is also improved.
In particular, the upper surface 36a of the facing ring 36 functions as a mounting surface for mounting the windshield 18, so that the upper surfaces 36a and 74a of the facing ring 36 and the insulating member 74 form the substantially same plane. Since a smooth placement surface is formed on the ring 36, the windshield 18 can be placed reliably.

Further, the inclined surface 36b extending downward from the upper surface 36a of the dial ring 36 toward the dial 24 functions as an index surface on which an index indicating the function display of the timepiece is arranged.
Therefore, if the inclined surfaces 36b and 74b of the turning ring 36 and the insulating member 74 form substantially the same plane, a smooth index surface is formed on the turning ring 36, so that it is easy to read the index. Further, when the index is printed on the index surface, the index can be printed very easily on the smooth index surface.

  In this case, the insulating material constituting the insulating member 74 is not particularly limited, and for example, a non-conductive insulating material such as synthetic resin, rubber, or ceramic can be employed.

  It is also possible to use a member in which a nonconductive film is coated on a conductive material. In this case, the conductive material constituting the insulating member 74 is, for example, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or these, as with the conductive material constituting the dial ring 36. An alloy of the above can be used. Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like can be employed.
