Abstract

A mobile electronic device includes: a body unit that includes a waterproof area; and a cover unit that covers the waterproof area. One of the cover unit and the body unit includes: a sealing member that contacts a contact surface formed on a same plane as the other all along the periphery of the waterproof area, and seals the waterproof area; and a regulation unit that regulates the position of the sealing member.

First claim

What is claimed is:

1. A mobile electronic device, comprising:
a body unit that includes a waterproof area; and
a cover unit that covers the waterproof area, wherein
one of the cover unit and the body unit includes: a sealing member that contacts a contact surface formed on a same plane as another of the cover unit and the body unit all along a periphery of the waterproof area and seals the waterproof area;
a plurality of regulation units that regulates a position of the sealing member;
a first nail unit engaged in another of the cover unit and the body unit; and
a resin sheet including the sealing member formed on a surface,
the plurality of regulation units regulate the position of the sealing member by touching the resin sheet,

a first regulation unit of the plurality of regulation units is provided as a unitary construction with the first nail unit,
the resin sheet is formed in frame form all along the periphery of the waterproof area,
and second regulation units of the plurality of regulation units touch an inner periphery surface of the resin sheet in frame form.

2. The mobile electronic device according to claim 1 , wherein:
the first regulation unit and the first nail unit are provided as a unitary construction at a convex part that projects from the one of the cover unit and the body unit including a rectangular section one of whose four sides is open;
the first regulation unit regulates the position of the sealing member at an open side end part of the convex part; and
the nail first unit is provided at a close side end part opposite the open side end part.

3. The mobile electronic device according to claim 1 , wherein:
the one of the cover unit and the body unit further comprises a second nail unit engaged in the another and a coupling unit that is provided as a unitary construction with the two nail units and connects the two nail units; and
the first regulation unit is provided as a unitary construction with the two nail units and the coupling unit.

4. The mobile electronic device according to claim 1 , wherein a third regulation unit of the plurality of regulation units is provided as a unitary construction with a wall surface provided around the one of the cover unit and the body unit so that the third regulation unit projects from the wall surface.

5. The mobile electronic device according to claim 4 , wherein the third regulation unit projects from the wall surface so that an open side end part including a rectangular section one of whose four sides is open faces the wall surface, and regulates the position of the sealing member at a close side end part opposite the open side end part.

6. The mobile electronic device according to claim 4 , wherein the third regulation unit projects from the wall surface so that an open side end part as one side of an H-shaped section faces the wall surface, and regulates the position of the sealing member at another open side end part.

7. The mobile electronic device according to claim 1 , wherein a third regulation unit of the plurality of regulation units is a wall surface provided around the one of the cover unit and the body unit.

8. The mobile electronic device according to claim 1 , wherein the one of the cover unit and the body unit further comprises a plurality of regulation units that touch an outer periphery surface of the resin sheet.

9. The mobile electronic device according to claim 1 , wherein the waterproof area is a battery storage unit.

10. A waterproof cover that is a cover unit that covers a waterproof area of a body unit of a mobile electronic device, comprising:
a sealing member that contacts all along a periphery of the area a contact surface formed on a same plane as the periphery of the waterproof area of the body unit, and seals the waterproof area;
a plurality of regulation units that regulate a position of the sealing member;
a nail unit engaged in the body unit; and
a resin sheet including the sealing member formed on a surface, wherein
the plurality of regulations units regulate the position of the sealing member by touching the resin sheet,
a first regulation unit of the plurality of regulation units is provided as a unitary construction with the nail unit,
the resin sheet is formed in frame form all along the periphery of the waterproof area, and
second regulation units of the plurality of regulation units touch an inner periphery surface of the resin sheet in frame form.
