Abstract

The cord reel device includes a reel body provided with a rotation shaft, a housing that stores inside the reel body in a rotatable manner, and a cord which is wound around the reel body so as to be extractable and which is extracted to an outside through an opening of the housing. The reel body has disk-shaped members on a plane perpendicular to the rotation shaft, and the cord is stored in a space formed between the disk-shaped members. A guide section inclined relative to the rotation shaft of the reel body is provided around peripheries of the disk-shaped members of the reel body. While the cord is wound around the reel body, the guide section guides the cord to the rotation shaft of the reel body.

First claim

What is claimed is:

1. A cord reel device comprising:
a reel body provided with a rotation shaft;
a housing that stores the reel body inside in a rotatable manner and has an opening;
a cord which is wound around the reel body so as to be extractable and which is extracted through the opening of the housing to an outside; and
a guide section that is disposed around a periphery of the reel body,
wherein the guide section includes an inclined surface, the inclined surface being inclined relative to the rotation shaft, and the inclined surface being in contact with the cord to guide the cord to be stored in the reel body.

2. The cord reel device according to claim 1 , wherein the inclined surface is inclined in a depth direction which is a direction from the opening of the housing toward a center of the rotation shaft.

3. The cord reel device according to claim 1 , wherein an opening area of the opening of the housing is set to be a sectional area of the cord.

4. The cord reel device according to claim 1 , wherein the cord moves along an inclination of the inclined surface due to a change in a winding diameter caused while storage of the cord into the reel body progresses.

5. The cord reel device according to claim 1 , wherein in a planer view, the guide section is disposed at a position where a square that includes a circle defining an outer shape of the reel body and has four sides of a length equal to a diameter of the circle does not overlap the circle.

6. An electronic device comprising:
a cord reel device which includes a reel body provided with a rotation shaft, and a cord wound around the reel body so as to be extractable;
a connection device connected to the cord and arranged adjacent to the cord reel device in a direction in which the cord is extracted; and
a guide section that is disposed around a periphery of the reel body between the reel body and the connection device,
wherein the guide section includes an inclined surface, the inclined surface being inclined relative to the rotation shaft, and the inclined surface being in contact with the cord to guide the cord to be stored in the reel body.

7. The electronic device according to claim 6 , wherein
the connection device is a controller having a rectangular shape and configured to be operated by an aircraft passenger,
the cord reel device is disposed adjacent to the controller in a longitudinal direction of the controller, and
the guide section is disposed between the reel body and the controller.

8. The cord reel device according to claim 1 , wherein the inclined surface is positioned to guide the cord so that the cord is wound around the reel body.
