Abstract

An eyeglasses-type wireless communications device includes: left and right eyepiece sections; pads; endpieces; temples; and an antenna element for carrying out wireless communications, and the antenna element is disposed in a region along an outer edge(s) of the right eyepiece section and/or the left eyepiece section, the region including corresponding one(s) of the endpieces but excluding connecting parts of the eyepiece sections which parts are connected to the respectively corresponding pads.

First claim

The invention claimed is:

1. An eyeglasses-type wireless communications device comprising:
an eyepiece section
pads;
endpieces; and
an antenna element for carrying out wireless communications,
the antenna element being disposed in a region along an outer edge of the eyepiece section, the region including corresponding one(s) of the endpieces but excluding connecting parts of the eyepiece section which parts are connected to the respectively corresponding pads.

2. The eyeglasses-type wireless communications device according to claim 1 , wherein
more than half part of the antenna element is disposed at a position closer to a corresponding one of the endpieces than to a corresponding one of the pads.

3. The eyeglasses-type wireless communications device according to claim 1 , further comprising:
temples,
wherein
the antenna element includes a first antenna element extending along the outer edge of the eyepiece section in one direction from a corresponding one of the endpieces, and
a power feeding line for supplying power to the first antenna element extends from a wireless section, which is provided on a corresponding one of the temples, so that the power feeding line is connected to the first antenna element via said corresponding one of the endpieces.

4. The eyeglasses-type wireless communications device according to claim 3 , wherein
the antenna element includes a second antenna element extending along the outer edge of the eyepiece section from a corresponding one of the endpieces in another direction opposite to the direction in which the first antenna element extends, and
a power feeding line for supplying power to the second antenna element extends from the wireless section so as to be connected to the second antenna element via said corresponding one of the endpieces.

5. The eyeglasses-type wireless communications device according to claim 4 , wherein
the first and second antenna elements constitute a dipole antenna.

6. The eyeglasses-type wireless communications device according to claim 4 , wherein
the first and second antenna elements differ from each other in at least one of shape and length.

7. The eyeglasses-type wireless communications device according to claim 4 , wherein
the first and second antenna elements constitute a diversity antenna.

8. The eyeglasses-type wireless communications device according to claim 1 , wherein
the eyepiece section comprises left and right eyepiece sections,
the antenna element includes a third antenna element being disposed along an outer edge of one of the left and right eyepiece sections, and
a power feeding line for supplying power to the third antenna element extends from a wireless section, which is provided between the left and right eyepiece sections, so that the power feeding line is connected to the third antenna element.

9. The eyeglasses-type wireless communications device according to claim 8 , wherein
the antenna element includes a fourth antenna element being disposed along an outer edge of the other of the left and right eyepiece sections, and
a power feeding line for supplying power to the fourth antenna element extends from the wireless section so as to be connected to the fourth antenna element.

10. The eyeglasses-type wireless communications device according to claim 9 , wherein
the third and fourth antenna elements each constitute a monopole antenna.

11. The eyeglasses-type wireless communications device according to claim 9 , wherein
the third and fourth antenna elements differ from each other in at least one of shape and length.

12. The eyeglasses-type wireless communications device according to claim 9 , wherein
the third and fourth antenna elements constitute a diversity antenna.

13. The eyeglasses-type wireless communications device according to claim 1 , further comprising:
a rim surrounding the eyepiece section, wherein
at least part of the antenna element is disposed between the eyepiece section and the rim.

14. The eyeglasses-type wireless communications device according to claim 1 , further comprising:
a rim surrounding the eyepiece section, wherein
at least part of the antenna element is provided in the rim.

15. The eyeglasses-type wireless communications device according to claim 1 , wherein
the antenna element is provided to a part of the eyeglasses-type wireless communications device which part does not come into contact with a user.

16. The eyeglasses-type wireless communications device according to claim 1 , further comprising:
temples,
wherein
the pads and/or the temples are not provided with the antenna element.

17. The eyeglasses-type wireless communications device according to claim 1 , further comprising:
temples,
wherein
the antenna element comprises: a first antenna element extending along the outer edge of the eyepiece section in one direction from a corresponding one of the endpieces; and a second antenna element extending along the outer edge of the eyepiece section from a corresponding one of the endpieces in another direction opposite to the direction in which the first antenna element extends, and
the first antenna element and the second antenna element are supplied with power from a wireless section, which is provided on the temple, via said corresponding one of the endpieces.
