Abstract

An electronic device includes a case with an opening portion; a cover member arranged in the opening portion so as to close the opening portion; a seal member provided between an outer circumferential surface of the cover member and an inner circumferential surface of the opening portion; a reinforcing portion made of a nonconductive material and provided, in the case, on a portion outside the inner circumferential surface in a direction orthogonal to an axial direction of the opening portion; an antenna; and an electronic component arranged in the case and configured to process a radio wave received by the antenna.

First claim

What is claimed is:

1. An electronic device comprising:
a case with an opening portion;
a cover member arranged in the opening portion so as to close the opening portion;
a seal member provided between an outer circumferential surface of the cover member and an inner circumferential surface of the opening portion;
a reinforcing portion made of a nonconductive material and provided, in the case, on a portion outside the inner circumferential surface in a direction orthogonal to an axial direction of the opening portion;
an antenna; and
an electronic component arranged in the case and configured to process a radio wave received by the antenna.

2. The device of claim 1 , wherein the reinforcing portion is formed into an annular shape with the inner circumferential surface of the opening portion arranged inside.

3. The device of claim 1 , wherein the seal member is formed into an annular shape.

4. The device of claim 1 , wherein the reinforcing portion comprises an annular reinforcing member fitted on an outer circumferential surface of the opening portion.

5. The device of claim 1 , wherein the reinforcing portion is formed integrally with the outer circumferential surface of the opening portion.

6. The device of claim 1 , wherein the antenna is arranged on an opening end face of the case.

7. The device of claim 1 , wherein the nonconductive material comprises a resin.

8. The device of claim 1 , wherein the nonconductive material comprises a glass fiber.

9. The device of claim 1 , wherein the antenna receives a GPS signal.

10. An electronic device comprising:
an annular reinforcing member made of a nonconductive material;
a tubular case including a large-diameter portion and a small-diameter portion formed to continue to the large-diameter portion, wherein an outer diameter of the small-diameter portion is smaller than an outer diameter of the large-diameter portion and the small-diameter portion is fitted in the reinforcing member;
a cover member arranged in the small-diameter portion;
an annular seal member provided between an outer circumferential surface of the cover member and an inner circumferential surface of the small-diameter portion;
an antenna arranged on an opening end face of the case; and
an electronic component arranged in the case and configured to process a radio wave received by the antenna.

11. The device of claim 10 , wherein the reinforcing member is formed integrally with an outer circumferential surface of the large-diameter portion.

12. The device of claim 10 , wherein the nonconductive material comprises a resin.

13. The device of claim 10 , wherein the nonconductive material comprises a glass fiber.

14. The device of claim 10 , wherein the antenna receives a GPS signal.
