Portable terminal having earphone winding device built therein
First Claim
1. An earphone winding device in a portable terminal using an earphone, comprising:
- a housing formed in a body of the portable terminal;
a rotational bobbin fit in the housing so that the rotational bobbin is rotatable, the rotational bobbin having, at a center thereof, a spiral spring for applying an elastic force to the rotational bobbin and thus rotating the rotational bobbin;
a stopper formed at a predetermined position on the lower surface of the rotational bobbin, for restraining the rotation of the rotational bobbin or releasing the rotational bobbin from the restraint on rotation along with the rotation of the rotational bobbin;
an earphone cord wound around the rotational bobbin, while being connected to the earphone;
an earphone hanger formed at a predetermined position on an outer side surface of the body, for hanging or picking up the earphone thereover or therefrom; and
a connector unit formed on the lower surface of the body, for coming into an electrical contact with an earphone cord.

Abstract
An earphone winding device in a portable terminal using an earphone is disclosed. The earphone winding device comprises a housing formed in a portable terminal body. A rotational bobbin is rotatably fit in the housing. It has, at a center thereof, a spiral spring for applying an elastic force to the rotational bobbin and thus rotating the rotational bobbin. A stopper is formed at a predetermined position on the lower surface of the rotational bobbin, for restraining the rotation of the rotational bobbin or releasing the rotational bobbin from the restraint. An earphone cord is wound around the rotational bobbin, connected to the earphone. An earphone hanger is formed at a predetermined position on an outer side surface of the body, for hanging or picking up the earphone thereover or therefrom. A connector unit is formed on the lower surface of the body, for contacting an earphone cord.
