Abstract

A capacitive stylus pen for a portable terminal includes a body portion formed of a synthetic resin material extending in a longitudinal direction; a sensing member provided in an inner side of the body portion to sense a current of a human'"'"'s body; a transferring member formed of a conductive material and provided in an end of the body portion to be connected to the sensing member, and a manipulating member provided in an end of the transferring member, wherein the manipulating member is manufactured of conductive rubber and contacts a touch screen according to user'"'"'s manipulation, and a Near Field Communication (NFC) is embedded in the body portion to perform wireless communication with the portable terminal, thereby configuring a wireless headset with the capacitive stylus pen.

Claims

1. A capacitive stylus pen for a portable terminal, the capacitive stylus pen comprising:

a body portion formed of a synthetic resin material and extending in a longitudinal direction;

a sensing member provided in an inner side of the body portion to sense a current of a human'"'"'s body upon gripping the body portion;

a transferring member formed of a conductive material and provided in an end of the body portion to be connected to the sensing member; and

a manipulating member provided in an end of the transferring member,

wherein the manipulating member is manufactured of conductive rubber and is pressed against and contacts a touch screen according to user'"'"'s manipulation;

a binding hole provided in one end of the transferring member; and

a binding member provided in an end of the body portion,

wherein at least an end portion of the transferring member is inserted into the end of the body portion, and the binding member is engaged within the binding hole to fix the transferring member to the body portion.

2. The capacitive stylus pen of claim 1, wherein the binding member comprises a first screw engaged from an outer side of the body portion.

3. The capacitive stylus pen of claim 1, wherein the binding member comprises a binding protrusion formed on the inner circumferential surface of the body portion.

4. The capacitive stylus pen of claim 1, further comprising a near field communication (NFC) device embedded in the body portion to perform wireless communication.

5. A capacitive stylus pen for a portable terminal, the capacitive stylus pen comprising:

a body portion formed of a synthetic resin material and extending in a longitudinal direction;

a sensing member provided in an inner side of the body portion to sense a current of a human'"'"'s body upon gripping the body portion;

a first transferring member formed of a conductive material and provided in an end of the body portion to be connected to the sensing member;

a manipulating member provided in an end of the first transferring member,

wherein the manipulating member is manufactured of conductive rubber and is pressed against and contacts a touch screen according to user'"'"'s manipulation; and

a grip member arranged to enclose at least the first transferring member between the body portion and the manipulating member, wherein the grip member comprises;

a first receiving portion for receiving a portion of the first transferring member;

a second receiving portion for receiving a portion of the manipulating member; and

a barrier provided between the first receiving portion and the second receiving portion, and wherein a binding member comprises a first screw engaged from an outer side of the body portion, further comprising a second screw engaged to the first transferring member from the second receiving portion through the barrier.

6. The capacitive stylus pen of claim 5, wherein the second screw is formed of a conductive material and the manipulating member contacts the second screw as the manipulating member is received in the second receiving portion.

7. The capacitive stylus pen of claim 5, further comprising:

a second transferring member disposed in the second receiving portion; and

a connecting member extending from the second transferring member to the second receiving portion through the barrier,

wherein the second transferring member is engaged to the connecting member.

8. The capacitive stylus pen of claim 7, wherein the second transferring member is formed of a conductive material and the manipulating member is coupled to the second transferring member in the second receiving portion.
