Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of an electronic wrist watch with a receiving device having a receiving antenna built therein.

[0002]

[Prior Art]

 In recent years, the development of mobile devices using radio waves has been remarkable, and they have been commercialized in many fields. In the field of wristwatches, there are a few exceptions, including wristwatches with a radio, and a few that use radio waves have been commercialized. However, in order to use radio waves, in addition to the parts that are completely different from the conventional timepiece parts, consideration must be given so that reception performance is not hindered. Among them, the antenna, which has a great influence on the reception performance of radio waves, is considerably large in size as compared with the parts of conventional wristwatches, and the placement restrictions due to the relation of the reception performance. However, when it is installed inside the watch, there is a space problem, and it is difficult to downsize the wristwatch. Moreover, enclosing the antenna with a metal case must be avoided from the standpoint of receiving characteristics, which is a design limitation and poses a problem.

As a method for solving the above problems, a product having a structure in which the antenna is separated from the timepiece module has been commercialized. As the structure, an antenna is provided inside the band as seen in Japanese Utility Model Publication No. 2-126408, or an antenna is provided around the outer periphery of the watch case as seen in Japanese Utility Model Publication No. 64-38034. There are products that take in and make the wristwatch body smaller and thinner.

[0004]

[Problems to be solved by the device]

 However, the structure in which the antenna is provided inside the band or around the outer periphery of the watch case has no choice but to establish continuity between the antenna and the watch module inside the watch case, and considering the operating environment of the wristwatch, the waterproof property in this part is required. Considering the above, there are major structural constraints. Furthermore, if the antenna is installed inside the band, it is not possible to use a metal band because of the reception performance, and you must use a special watch band such as a leather band. There is a problem of coming restrictions. Similarly, when an antenna is provided on the outer circumference of the case, there is a problem in that the design is greatly restricted due to the linear antenna and the fixing and conducting structure of the antenna.

The present invention solves the above-mentioned conventional problems, facilitates the connection between the antenna and the timepiece module, does not affect the reception performance of the antenna, and has less restrictions on the design of the timepiece. Intended to provide watches.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following configuration. That is, the wristwatch with a receiving device according to the present invention is one in which an antenna is arranged on the display part of a timepiece module housed in a watch case, and the antenna is an antenna winding wound around an antenna core. The wire ends are fixed and the antenna terminal sheets with conductive antenna terminal sheets are fixed at both ends.The antenna terminal frames are inserted into the watch module from above the timepiece display and screwed to the antenna support plate of the timepiece module. By doing so, it is characterized by conducting and fixing with the clock module.

[0007]

[Action]

 After the timepiece module is completed, by providing an antenna on the display to connect and fix the timepiece module, the antenna and the timepiece module can be easily connected / fixed, and special consideration is given to waterproofing. It is also unnecessary, and by disposing the antenna on the display, it is separated from the clock module, and the effect on reception performance is reduced.

The module is fixed.

Here, a mounting process of the antenna 19 will be described. For the antenna 19, the dial 10 is attached to the timepiece module, the hands 11 to 17 are attached, and then the antenna reel 19c is inserted from the notch 10k of the dial 10. As a result, the screwing hole 19dd of the antenna terminal sheet 19d and the hole 33a of the antenna support plate 33 are aligned with each other, and the screw 41 is screwed in the antenna fixing tube 19e from the lateral direction of the timepiece module. 19 is fixed to the timepiece module and is electrically connected to the circuit board 22. On the other hand, in terms of reception performance, the mounting cross-sectional position of the antenna 19 fixed in this way is different from that of the watch case 1 and is almost at the same cross-sectional position as the bezel 2. It does not interfere with the reception performance of 19.

As described above, since the antenna can be attached after the hands are attached, the hands can be attached like an ordinary analog timepiece without being disturbed by the antenna. Also, an antenna with a large size and an antenna core made of ferrite that is fragile to shocks and wound with a thin antenna winding that is easy to cut on the outer circumference is installed just before mounting it in the watch case, so it is practical for damage to the antenna It has a very effective effect. Further, since the antenna 19 is provided on the dial plate 10, it is possible to use a metal material for the timepiece case except the antenna in cross section, and there is also an effect that there is no restriction on the material. Further, since the antenna 19 is provided above the dial plate 10 separately from the timepiece module, there is an effect that the influence of various timepiece components is reduced as compared with the case where the antenna 19 is provided in the timepiece module.

FIG. 5 is a sectional view taken along line BB of FIG. The antenna 19 is provided between the recess 3a of the windshield 3 and the recess 10m of the dial 10, and is fixed to the windshield 3 and the dial 10 with a gap therebetween. As a result, in the event of an impact, the windshield 3 and the dial 10 are not directly impacted, so that the antenna core 19a can be prevented from being damaged. Further, the distance between the windshield 3 and the dial 10 is necessary and sufficient for attaching the hands 11 to 16, and the antenna 19 prevents the timepiece from becoming thick.

[Effect of the device]

 As is clear from the above description, the electronic wrist watch with a receiving device of the present invention has a considerable size in comparison with the conventional timepiece parts, and does not impair the receiving performance. By providing an antenna above the display that needs to be taken into consideration and making it independent of the timepiece module, there is the effect that the timepiece module structure can be simplified and downsized. Further, since the antenna is not provided outside the watch case such as a watch band, the antenna and the watch module can be easily conducted, and it is not necessary to consider the waterproof property of this part, which is a great structural advantage.

Since the antenna can be attached after the hands are attached, the hands can be attached without being disturbed by the antenna as in a normal analog timepiece, and an antenna core that is large in size and is vulnerable to impact can be used. The antenna, which has a thin antenna winding that is easy to cut on the outer periphery, is attached immediately before it is installed in the watch case, so it has a very effective practical effect against damage to the antenna.

Furthermore, since the antenna is provided on the dial, it is possible to use a metal material for the watch case in the part except the antenna in cross section, and there is also an effect that there is no restriction on the material. On the other hand, since the antenna is located above the display, that is, above the watch, it is an effective arrangement for radio wave characteristics, and because it is separated from the watch module, it can be used for various watch parts rather than being installed in the watch module. There is also an effect that the reception characteristics are less affected.

On the other hand, since the antenna is provided in the watch case, it is not necessary to use a dedicated watch band and it is possible to use a metal band. Moreover, by overlapping the antenna with the display part in a plane, the size of the watch with respect to the plane profile can be reduced. This has the effect of eliminating the restrictions on large antennas and reducing the restrictions on the design.
