[0002]

2. Description of the Related Art In recent years, the development of portable devices using radio waves has been remarkable and commercialized in many fields. In the field of wristwatches, there are no exceptions, such as wristwatches equipped with radios, and a few that use radio waves have been commercialized. However, in order to use radio waves, components that are completely different from conventional watch components are required, and consideration must be given not to hinder reception performance. Among them, the antenna which has a great influence on the reception performance of radio waves in particular has a considerable size in comparison with parts of conventional wristwatches in terms of size, and furthermore, there is a restriction on the arrangement from the relation of the reception performance. However, if it is provided inside the timepiece, there is a space problem and it is difficult to reduce the size of the wristwatch. In addition, it is necessary to avoid surrounding the antenna with a metal case from the viewpoint of the reception characteristics, which is a problem in design restrictions.

As a method for solving the above-mentioned problems, products having a structure in which an antenna is separated from a timepiece module have been commercialized. The structure is as follows:
No. 8, etc., a structure in which the antenna is provided in the band, or a structure, in which the antenna is provided on the outer periphery of the watch case as shown in Japanese Utility Model Application Publication No. 64-38034, etc. There are products etc.

[0004]

However, the structure in which the antenna is provided in the band or the structure in which the antenna is provided on the outer periphery of the watch case is forced to establish conduction between the antenna and the watch module in the watch case. When considering the waterproofness of this part in consideration of the above, there is a great restriction on the structure. Furthermore, when the antenna is provided in the band, it is impossible to use a metal band from the reception performance,
You must use a dedicated watch band such as a leather band,
There is a problem with the design of the whole watch that comes from the watch band. Similarly, in the case where the antenna is provided on the outer periphery of the case, there is a problem that the linear antenna and the fixing and conducting structure of the antenna greatly restrict the design.

[0005] The present invention is to solve the conventional problems as described above, is easy to connect the antenna and the watch module, without affecting the reception performance of the antenna, yet electronic design with constraints of the watch is small receiving device It aims to provide mobile watches .

[0006]

In order to achieve the above object, the present invention has the following configuration. That is,
Receiving apparatus with an electronic watch according to this invention includes a windshield, the timepiece module, and a dial of a display surface disposed between the windshield and the module, the windshield and the dial <br/> An antenna disposed between the antenna core, the antenna comprises a linear antenna core, a winding wound around the antenna core, and a terminal sheet that conducts with the winding;
The terminal sheet is electrically connected to the timepiece module, and the antenna is disposed at a portion of the display surface at a maximum distance, and display portions are provided on both sides of the antenna.
Characterized in that it. The display unit is a pointer display unit , wherein the antenna is disposed in a diameter direction passing through the center of the dial, and at least a part of the antenna is formed on the windshield or the dial. It is characterized in that it is housed in a recess.

[0007]

After the watch module is completed, an antenna is provided on the display unit to conduct and fix the watch module, so that conduction / fixing between the antenna and the watch module can be easily performed, and furthermore, waterproofing is achieved. Special considerations are no longer required, and the placement of the antenna on the display separates it from the clock module, reducing the impact on receiving performance.

[0022]

As is apparent from the above description, according to the electronic portable timepiece with the receiving device of the present invention, the size and the size of the timepiece are considerably larger than those of the conventional timepiece parts. The antenna, which needs to be considered so as not to hinder the performance, is straightened and provided at the maximum distance on the display unit, and is independent of the clock module, so that the clock module structure can be simplified and downsized. effective. Also,
Display parts are provided on both sides of the antenna,
For example, reception at the antenna other than the time is correct.
Secure enough space for indication of whether it is normal
can do. Furthermore, since the antenna is not provided on a part other than the watch case such as a watch band, and is disposed inside the case, conduction between the antenna and the watch module is easy, and it is not necessary to consider the waterproofness of the antenna and the conductive part. , Is a great advantage in structure.

Since the antenna can be attached after attaching the hands, it can be attached without being disturbed by the antenna like a normal analog timepiece, and has a large antenna core which is fragile against impact. However, since the antenna whose outer periphery is wound with a thin antenna winding which is easy to cut is mounted immediately before being incorporated into the watch case, there is a very effective effect practically against damage to the antenna.

Further, since the antenna is provided on the dial, it is possible to use a metal material for the timepiece case except for the antenna in a sectional view, and there is also an effect that the material is not restricted. On the other hand, since the antenna is arranged above the display unit, that is, above the watch, it is an effective arrangement with respect to the radio wave characteristics, and since it is separated from the watch module,
There is also an effect that the influence on the reception characteristics of various timepiece components is reduced as compared with the case where the timepiece is provided in the timepiece module.

On the other hand, part of the antenna is placed inside the watch case.
Since it was stored in the recess formed in the windshield,
The thickness of the entire watch can be reduced while having a tena,
In addition to being effective in terms of use, it is possible to use a metal band without the need for a dedicated watch band, and by superimposing the antenna on the display unit in a plane, there is no restriction on large antennas with respect to the plane profile of the watch. This has the effect of reducing design constraints.
