Abstract

A timepiece module includes a digital display screen, an antenna device and a metallic component. The antenna device includes an antenna pattern relevant to communication and an antenna component connected to and extending from the antenna pattern. In a plan view, the antenna pattern has a curved shape and overlaps the digital display screen. The antenna device is disposed such that either one side or other side on a virtual line does not overlap the metallic component. The virtual line is an extending direction in which the antenna component, which extends from the antenna pattern, extends.

First claim

The invention claimed is:

1 . A timepiece module comprising:
a digital display screen; an antenna device including an antenna pattern relevant to communication and an antenna component connected to and extending from the antenna pattern; and a metallic component, wherein, in a plan view, the antenna pattern has a curved shape and overlaps the digital display screen, and wherein the antenna device is disposed such that either one side or other side on a virtual line that is an extending direction in which the antenna component, which extends from the antenna pattern, extends does not overlap the metallic component.

2 . The timepiece module according to claim 1 , wherein the antenna component is rectangular in the plan view.

3 . The timepiece module according to claim 2 , wherein the extending direction of the antenna component is a lengthwise direction of the antenna component.

4 . The timepiece module according to claim 3 , wherein, between the one side and the other side on the virtual line, a side that does not overlap the metallic component is a peripheral side of the timepiece module.

5 . The timepiece module according to claim 1 , wherein the antenna device is used for short-range wireless communication.

6 . The timepiece module according to claim 2 , wherein the antenna device is used for short-range wireless communication.

7 . The timepiece module according to claim 3 , wherein the antenna device is used for short-range wireless communication.

8 . The timepiece module according to claim 4 , wherein the antenna device is used for short-range wireless communication.

9 . The timepiece module according to claim 1 , wherein the antenna pattern is longer than a length corresponding to a wavelength of a frequency to be used.

10 . The timepiece module according to claim 2 , wherein the antenna pattern is longer than a length corresponding to a wavelength of a frequency to be used.

11 . The timepiece module according to claim 3 , wherein the antenna pattern is longer than a length corresponding to a wavelength of a frequency to be used.

12 . The timepiece module according to claim 4 , wherein the antenna pattern is longer than a length corresponding to a wavelength of a frequency to be used.

13 . The timepiece module according to claim 9 , wherein the frequency to be used is a frequency for short-range wireless communication.

14 . The timepiece module according to claim 10 , wherein the frequency to be used is a frequency for short-range wireless communication.

15 . The timepiece module according to claim 11 , wherein the frequency to be used is a frequency for short-range wireless communication.

16 . The timepiece module according to claim 12 , wherein the frequency to be used is a frequency for short-range wireless communication.

17 . The timepiece module according to claim 1 , wherein the metallic component is a reference distance or greater away from the antenna pattern.

18 . The timepiece module according to claim 1 , wherein the curved shape is a circular arc shape.

19 . An electronic timepiece comprising the timepiece module according to claim 1 .

20 . An electronic timepiece comprising the timepiece module according to claim 4 .
