Abstract

A portable electronic device (10) includes a first housing (20), an electronic module (32), a first cover (30), a circuit board module (33), and a second cover (35). The electronic module (32) is secured on to one of faces of the first housing (20). The first cover (30) is watertightly attached to the first housing (20) via a waterproof adhesive member (31) to cover the electronic module (32). The circuit board module (33) is secured on another face of the first housing (20). The second cover (35) is watertightly attached to the first housing (20) via a waterproof adhesive member (34) to cover the circuit board module (33).

Claims

1. A portable electronic device comprising:

a first housing;

an electronic module fixed to one of faces of the first housing and having an electronic part;

a first cover covering the electronic module by being watertightly attached to the first housing via a waterproof adhesive member;

a circuit board module fixed to the other face of the first housing and including a circuit board; and

a second cover covering the circuit board module by being watertightly attached to the first housing via a waterproof adhesive member.

2. The portable electronic device according to claim 1, wherein a first

recess is formed in the one of the faces of the first housing,

a second recess is formed in the other face of the first housing,

the electronic module is stored in the first recess, and

the circuit board module is stored in the second recess.

3. The portable electronic device according to claim 2, wherein the first housing has a metal plate and a resin part covering a periphery of the metal plate and formed in an almost frame shape,

the first recess and the second recess are defined by an inner peripheral face having an almost frame shape of the resin and a surface of the metal plate, and

the electronic module and the circuit board module are fixed on the surface of the metal plate.

4. The portable electronic device according to claim 3, wherein an amount of resin of the resin part formed on one of faces of the metal plate is equal to an amount of resin formed on the other face of the metal plate.

5. The portable electronic device according to claim 2, wherein a first adhesion face for adhering the adhesive member is formed along the periphery of the first recess in one of faces of the first housing, and

a second adhesion face for adhering the adhesive member is formed along the periphery of the second recess in the other face of the first housing.

6. The portable electronic device according to claim 5, wherein a storing part for storing an internal part and a canopy covering at least a part of the storing part in the thickness direction of the portable electronic device are formed in the one of the faces of the first housing,

a part of the first or second adhesion face is formed in one of the faces of the canopy, and

the internal part and the adhesive member are disposed so as to be at least partly overlapped in the thickness direction of the portable electronic device.

7. The portable electronic device according to claim 1, wherein the electronic module has a display unit for displaying information to the user.

8. The portable electronic device according to claim 1, further comprising:

a second housing;

a hinge unit connecting the first and second housings so as to be capable of turning; and

a fastening screw fixing the hinge unit to the first housing,

wherein the fastening screw is screwed in the first housing in a direction perpendicular to the thickness direction of the first housing.

9. The portable electronic device according to claim 8, wherein a third recess for storing a screw head of the fastening screw screwed in the first housing is formed in the first housing.

10. The portable electronic device according to claim 8, wherein the fastening screw and the adhesive member are disposed so as to be at least partly overlapped in the thickness direction of the portable electronic device.
