Abstract

An electronic device includes: an enclosure that has an opening formed therein; a switch disposed in the enclosure opposite the opening; a key top member disposed inside the opening; and a water sealing member that has a wall part which extends such that a height direction of the wall part coincides with an opening direction of the opening and which seals an inner surface of the opening, an arm part which extends from the wall part to the inner side of the opening and supports the key top member, and a wall part reinforcer provided in the wall part.

First claim

What is claimed is:

1. An electronic device comprising:
an enclosure that has an opening formed therein;
a switch disposed in the enclosure opposite the opening;
a key top member disposed inside the opening;
a water sealing member that has a wall part which extends such that a height direction of the wall part coincides with an opening direction of the opening and which seals an inner surface of the opening, an arm part which extends from the wall part to the inner side of the opening and supports the key top member, and a wall part reinforcer provided in the wall part; and
a holder member that has a supporting part to support the switch, and an extending part which extends from the supporting part to an opening side of the enclosure, wherein
a lower end of the wall part is fixed to an end of the extending part,
the wall part reinforcer has a reinforcer body which extends such that the height direction of the reinforcer body coincides with the height direction of the wall part, and a bent portion formed by bending the reinforcer body at a lower end thereof toward an outer side of the opening, and
the bent portion is secured between an opening edge of the opening on the side of the extending part and the end of the extending part.

2. The electronic device according to claim 1 , wherein
the arm part is positioned between the key top member and the switch, and extends from a height-direction middle portion of the wall part to the inner side of the opening and to the side of the key top member, and
the key top member presses the switch by causing a flipping motion of the arm part across a virtual center line that is orthogonal to the opening direction of the opening and passes through a connecting portion between the arm part and the wall part.

3. The electronic device according to claim 2 , wherein the key top member is a fingerprint sensor module.

4. The electronic device according to claim 1 , wherein
a central axis line through the opening, the switch, and the key top member is inclined relative to a thickness direction of the enclosure.

5. The electronic device according to claim 4 , wherein the key top member is a fingerprint sensor module.

6. The electronic device according to claim 1 , wherein the key top member is a fingerprint sensor module.

7. An electronic device comprising:
an enclosure that has an opening formed therein;
a switch disposed in the enclosure opposite the opening;
a key top member disposed inside the opening; and
a water sealing member that has a wall part which extends such that a height direction of the wall part coincides with an opening direction of the opening and which seals an inner surface of the opening, an arm part which extends from the wall part to the inner side of the opening and supports the key top member, and a wall part reinforcer provided in the wall part, wherein
the water sealing member is a separate piece from the wall part reinforcer and has an arm part reinforcer provided at an end of the arm part, and
the arm part reinforcer is fixed to the key top member.

8. The electronic device according to claim 7 , wherein the arm part reinforcer is fixed to the key top member with double-sided adhesive tape.

9. The electronic device according to claim 8 , wherein the key top member is a fingerprint sensor module.

10. The electronic device according to claim 7 , wherein the key top member is a fingerprint sensor module.
