## Abstract

An electronic apparatus includes an exterior cover including a strap attachment portion, a circuit board on which an electric element that generates heat is mounted, and a chassis member to which the circuit board is fixed and through which the heat generated by the electric element is transferred. The chassis member is formed of a metallic material, and the chassis member includes a reinforcing portion arranged to overlap the strap attachment portion to reinforce the strap attachment portion. The reinforcing portion is disposed to be exposed inside the strap attachment portion.

## Claims

### Claim 1

An electronic apparatus to which can be attached a strap cord, the electronic apparatus comprising:
a circuit board on which an electric element that generates heat is mounted;
a chassis member to which the circuit board is fixed and through which the heat generated by the electric element is transferred;
an interior member which is fixed to the chassis member; and
an exterior cover which covers both of at least a part of the chassis member and at least a part of the interior member,
wherein the exterior cover includes a strap attachment portion,
wherein the interior member includes a strap reception portion,
wherein the chassis member is formed of a metallic material and includes a reinforcing portion arranged to overlap the strap attachment portion, and
wherein a space is provided between the reinforcing portion and the strap reception portion for passing through the strap cord
wherein a front end portion of the reinforcing portion is not fixed to the interior member, and
wherein the front end portion of the reinforcing portion is disposed on the line connecting fixing portions for fixing the chassis member and the exterior cover.

### Claim 2 (depends on 1)

The electronic apparatus according to claim 1, wherein the interior member is a battery storage chamber for storing a battery.

### Claim 3 (depends on 1)

The electronic apparatus according to claim 1, wherein a rib for covering an end surface of the reinforcing portion is formed on the strap attachment portion.

### Claim 4 (depends on 1)

The electronic apparatus according to claim 1, wherein the chassis member is formed of a plate-shaped metallic material that is punched, and an end surface of the reinforcing portion contacted by the strap cord attached to the strap attachment portion becomes a burr surface, and wherein the burr surface is subjected to a chamfering process.

### Claim 5 (depends on 1)

The electronic apparatus according to claim 1, wherein the chassis member is formed of a plate-shaped metallic material that is punched, and an end surface of the reinforcing portion contacted by the strap cord attached to the strap attachment portion becomes a rollover surface.

### Claim 6

An electronic apparatus to which can be attached a strap cord, the electronic apparatus comprising:
an interior member including a strap reception portion;
a chassis member to which the interior member is fixed; and
an exterior cover which covers both of at least a part of the chassis member and at least a part of the interior member,
wherein the exterior cover includes a strap attachment portion,
wherein the chassis member is formed of a metallic material,
wherein the chassis member includes a reinforcing portion arranged to overlap the strap attachment portion,
wherein a space is provided between the reinforcing portion and the strap reception portion for passing through the strap cord,
wherein a front end portion of the reinforcing portion is not fixed to the interior member, and
wherein the front end portion of the reinforcing portion is disposed on the line connecting fixing portions for fixing the chassis member and the exterior cover.

### Claim 7 (depends on 6)

The electronic apparatus according to claim 6, wherein an end surface of the reinforcing portion contacted by the strap cord attached to the strap attachment portion becomes a burr surface, and wherein the burr surface is subjected to a chamfering process.

### Claim 8 (depends on 6)

The electronic apparatus according to claim 6, wherein an end surface of the reinforcing portion contacted by the strap cord attached to the strap attachment portion becomes a rollover surface.
