Abstract

An electronic device and time piece are shown. The electronic device includes: a plurality of antenna devices; a plurality of motors; and antimagnetic plates, each fully or partially covering the motors and having cutouts at positions overlapping with the antenna devices.

First claim

What is claimed is:

1. An electronic device comprising:
a plurality of antenna devices;
a plurality of motors; and
antimagnetic plates, each antimagnetic plate at least partially covering at least one of the motors and having cutouts at positions overlapping with the antenna devices such that the antimagnetic plates do not overlap with the antenna devices,
wherein a first antimagnetic plate among the antimagnetic plates comprises (i) an antimagnetic plate body disposed at one of a viewer side of the motors and a side of the motors opposite the viewer side, and (ii) a side cover that is integrated with and extends from the antimagnetic plate body, the side cover being disposed along and covering a side of coils of at least one of the plurality of motors.

2. The electronic device according to claim 1 , wherein a second antimagnetic plate among the antimagnetic plates comprises an antimagnetic plate body disposed at the other one of the viewer side of the motors and the side of the motors opposite the viewer side.

3. The electronic device according to claim 2 , wherein the side cover is disposed along and covers sides of the coils of motors, from among the plurality of motors, which are disposed near a periphery of a module.

4. The electronic device according to claim 1 , wherein at least some of the antenna devices are at least partially superimposed in a thickness direction which is a direction perpendicular to a plane direction of the antimagnetic plates.

5. The electronic device according to claim 2 , wherein at least some of the antenna devices are at least partially superimposed in a thickness direction which is a direction perpendicular to a plane direction of the antimagnetic plates.

6. The electronic device according to claim 3 , wherein at least some of the antenna devices are at least partially superimposed in a thickness direction which is a direction perpendicular to a plane direction of the antimagnetic plates.

7. The electronic device according to claim 2 , wherein the motors are disposed between the first antimagnetic plate and the second antimagnetic plate.

8. The electronic device according to claim 3 , wherein the motors are disposed between the first antimagnetic plate and the second antimagnetic plate.

9. The electronic device according to claim 5 , wherein the motors are disposed between the first antimagnetic plate and the second antimagnetic plate.

10. The electronic device according to claim 6 , wherein the motors are disposed between the front antimagnetic plate and the rear antimagnetic plate.

11. A timepiece, comprising:
the electronic device according to claim 1 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

12. A timepiece, comprising:
the electronic device according to claim 2 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

13. A timepiece, comprising:
the electronic device according to claim 3 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

14. A timepiece, comprising:
the electronic device according to claim 4 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

15. A timepiece, comprising:
the electronic device according to claim 5 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

16. A timepiece, comprising:
the electronic device according to claim 6 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

17. A timepiece, comprising:
the electronic device according to claim 7 ;
a display displaying the time; and
a case accommodating the electronic device and the display.

18. An electronic device comprising:
a plurality of antenna devices;
a plurality of motors; and
antimagnetic plates, each antimagnetic plate at least partially covering at least one of the motors and having cutouts at positions overlapping with the antenna devices,
wherein at least some of the antenna devices are at least partially superimposed in a thickness direction which is a direction perpendicular to a plane direction of the antimagnetic plates.

19. The electronic device according to claim 18 , wherein the antimagnetic plates consist of a front antimagnetic plate disposed on a viewer side of the motors and a rear antimagnetic plate disposed on a side of the motors opposite the viewer side, and the motors are disposed between the front antimagnetic plate and the rear antimagnetic plate.

20. A timepiece, comprising:
the electronic device according to claim 18 ;
a display displaying the time; and
a case accommodating the electronic device and the display.
