Looking at the operation effect according to an embodiment of the present invention configured as described above is usually in close contact with the large cylindrical concave spring 10 built in the holder (9) of the antenna tube fixing portion 13 of the helical coil support (12) Is supported, and the wire fixing part 20 is held in close contact with the small cylindrical concave spring 17 embedded in the upper coil support 19 so that the antenna is built in the terminal 1 and the antenna head 3 is pulled out. The helical coil part 5 is drawn out by the wire stopper catching jaw 24 of the wire stopper 18 fixed to the lower end of the wire 4, and the helical coil part 5 is separated from the terminal by a predetermined distance 22. When the stopper is caught, the stopper locking jaw 23 is caught by the holder 9 to complete the withdrawal. When folding the antenna, the wire stopper 18, which is held in close contact with the small cylindrical concave spring 17 by pressing the antenna head 3, is moved downward, and the wire fixing portion 20 at the bottom of the antenna head 3 is replaced by the small cylinder. The stopper 11, which is held in close contact with the concave spring 17 and is pressed further, is pressed down and supported by the large cylindrical concave spring 10, and moves downward. Instead, the antenna tube fixing part 13 of the helical coil support 12 is moved. The large cylindrical concave spring 10 is inserted in close contact.

이상에서 설명한 본 발명은 전술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 있어 명백한 것이다.The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and alterations are possible within the scope without departing from the technical spirit of the present invention. It is evident to those who have knowledge of.

전술한 바와 같이, 본 발명에 따르면 평상시에는 단말기(1)내에 삽입되어 있고 사용시에는 안테나머리(3)을 뽑으면 순차적으로 안테나와이어(4)가 뽑히고 연이어 헬리컬코일(15)이 내장된 헬리컬코일부(5)가 단말기상으로 소정 거리 이격되게 인출되도록 함으로써 잡음원으로부터 이격되도록 하여 안테나 특성을 개선할 수 있고 안테나와이어(4) 및 스프링형태의 안테나튜브(6)에 의해 외력에 의한 변형이나 손상의 염려를 줄일 수 있는 효과가 있다. As described above, according to the present invention, when the antenna head 3 is inserted into the terminal 1 during normal use and the antenna head 3 is pulled out in succession, the helical coil part in which the helical coil 15 is sequentially connected is pulled out. 5) can be drawn away from the noise source by being drawn out a predetermined distance on the terminal to improve the antenna characteristics and the fear of deformation or damage caused by external force by the antenna wire (4) and the spring-shaped antenna tube (6) There is an effect that can be reduced.
