ある。2. Description of the Related Art There are few examples of wristwatches having antennas for receiving radio waves in the past, which are commercially available using bar antennas. A wristwatch in which an amorphous alloy is layered and an enamel wire is wound thereon, or a simple wristwatch is used. It can be seen that a good conductor loop is disposed inside a band made of rubber or urethane. In addition, Japanese Utility Model Publication No. 59-37584
There is also an example in which the antenna coil disclosed in Japanese Unexamined Patent Publication (Kokai) No. 59-37586 is mounted inside the glass or on the lower surface of the glass.

計ケース構造を提供することにある。If the enameled wire wound around the above-mentioned conventional example or a loop-shaped one is disposed inside the rubber band, the rubber band becomes extremely thick and the outer appearance becomes large. It is not preferable in view of the above, and there is a further disadvantage that the band is hard and does not fit into the arm when worn. Further, the above two utility models have drawbacks such as insufficient glass strength due to non-uniformity of the glass cross section, and a decrease in receiving ability due to the loop shape of the antenna.
An object of the present invention is to improve the above drawbacks, and at the same time, to use a bar shape (cylindrical shape) as an antenna shape for receiving a radio wave, and to provide waterproofness, strength, beautiful appearance, and comfort to an arm necessary for a watch case. It is an object of the present invention to provide a watch case structure of a radio controlled watch that maintains a comfortable mounting.

While fixing the cover glass formed in a cylindrical shape at right angles to the concave portion and the concave portion for arranging, the surface of the bezel is lower than the uppermost surface of the cover glass, The bar antenna is provided in a concave portion.

A bezel 7 made of a non-conductive material such as wood is fixed via a resin packing. A recess 6 for disposing the bar antenna 1 on the back surface and a cover glass 2 formed in a cylindrical shape at right angles to the recess 6 on the front surface are fixed to the bezel 7 via resin packing. Have been. The bar antenna 1 for receiving radio waves
Are arranged in the concave portion 6 of the cover glass 2 and
It is located between the dial 3 and is connected to the module 5 through two holes 4 formed in the dial 3. The bar antenna 1 needs a diameter of 3 to 5 m / m from the viewpoint of securing a sufficient receiving capability, and occupies about 60% to 70% of the total thickness of a normal wristwatch. Becomes thicker, which poses a problem in appearance. In order to cover this point, the cover glass 2 has a concave portion 6 in which the bar antenna 1 is disposed on the lower surface. Further, the cover glass 2 is made of a non-conductive material (ceramic, plastic,
Wood, etc.). On the other hand, the cover glass 2 is formed in a cylindrical shape in a direction perpendicular to the recess 6 in order to reduce the thickness of the side surface of the wristwatch and to maintain the strength of the cover glass 2. Further, since the surface of the bezel 7 is located at a position lower than the uppermost surface of the cover glass 2, the thickness of the wristwatch looks thin, and the watch has an excellent design.

Needless to say, the bar antenna 1 may be arranged above the surface of the dial 3 without providing the bar antenna. The bezel 7 can be fixed to the body 8 by bonding, caulking, welding, or the like without using packing. Further, in order to expand the design variation, it is also possible to provide a pattern or the like on the front and back surfaces of the cover glass 2 and the surface of the bar antenna 1 by printing, painting, or the like.

く拡大することとなった。As described above, according to the present invention, in a watch case structure of a radio-controlled timepiece having a radio wave receiving function using a bar antenna, a partial concave portion is formed on the lower surface of the cover glass,
In addition, by taking a structure in which a cover glass whose upper surface is formed into a cylindrical shape in a direction perpendicular to the concave portion is fixed to a bezel made of a non-conductive material, the thickness of the side surface of the wristwatch is made to be thinner than apparent. At the same time, from the viewpoint that the thickness of the cover glass can be sufficiently ensured, sufficient strength can be maintained, and functions such as the appearance, wearability, strength, and waterproofness of a wristwatch can be sufficiently included, and radio wave reception can be performed. The practicality of watches with functions has been significantly expanded.
