## Abstract

A portable electronic apparatus (wrist apparatus) includes a case (top case and bottom case), a display section accommodated in the case, a windshield that closes an opening section of the case in such a way that the windshield overlaps with the display section in a plan view, a ring member (parting plate) that is disposed between the windshield and the display section and along the outer edge of the display section, a hygroscopic member that is disposed inside the case and in a first region (internal space) opposite the windshield with respect to the display section, and an air-flow channel (recessed section) that allows the first region to communicate with a second region (space) surrounded by the display section, the windshield, and the ring member.

## Claims

### Claim 1

A portable electronic apparatus comprising:
a case;
a display section accommodated in the case;
a windshield that closes an opening section of the case in such a way that the windshield overlaps with the display section in a plan view;
a ring member that is disposed between the windshield and the display section and along an outer edge of the display section;
a hygroscopic member that is disposed inside the case and in a first region opposite the windshield with respect to the display section; and
an air-flow channel that allows the first region to communicate with a second region surrounded by the display section, the windshield, and the ring member.

### Claim 2 (depends on 1)

The portable electronic apparatus according to claim 1,
wherein the air-flow channel includes a recessed section provided in a surface that forms the ring member and faces the display section and extending from an outer circumferential edge of the ring member to an inner circumferential edge thereof.

### Claim 3 (depends on 1)

The portable electronic apparatus according to claim 1,
wherein the air-flow channel includes a first hole that passes through the display section from a surface thereof facing the windshield to a surface thereof opposite the windshield-side surface.

### Claim 4 (depends on 3)

The portable electronic apparatus according to claim 3,
wherein the air-flow channel includes a second hole that faces the first hole and passes through the ring member from a surface thereof facing the windshield to a surface thereof facing the display section.

### Claim 5 (depends on 1)

The portable electronic apparatus according to claim 1,
wherein the air-flow channel includes a first recessed section that passes through the display section from a surface thereof facing the windshield to a surface thereof opposite the windshield-side surface and is recessed from an outer edge of the display section toward a center thereof.

### Claim 6 (depends on 1)

The portable electronic apparatus according to claim 1,
wherein the ring member has a protruding section that is located on a surface facing the display section and protrudes toward the display section, and
the air-flow channel includes a gap provided by the protruding section and located between the ring member and the display section.

### Claim 7 (depends on 1)

The portable electronic apparatus according to claim 1,
wherein the ring member is a parting plate.
