Patent ID: 7308109

Claim:
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; an earphone cord wound around the rotational bobbin, while being connected to the earphone; a stopper formed at a predetermined position on a lower surface of the rotational bobbin, for rotating or restraining the rotational bobbin by pulling an earphone cord clockwise and releasing it from the restraint when the earphone cord is wound counterclockwise, the stopper including: at least one stopper protrusion on the rotational bobbin; a guide rail formed at a predetermined position in the housing; a locker supported on the guide rail and being movable in an arcuate path in a clockwise or counterclockwise direction between a first position and a second position, said locker having a first end and a second end, said stopper protrusion engaging said first end of said locker and moving the locker to the first position when said rotational bobbin rotates in a first direction, and said stopper protrusion engaging said second end of said locker and moving the locker to the second position when said rotational bobbin rotates in a second direction; an earphone hanger formed at a predetermined position on an outer side surface of the body, for hanging or picking up the earphone thereto or therefrom; and a connector unit formed on a lower surface of the body, for coming into an electrical contact with an earphone cord.
