A braking step 224 is formed on one side of the lower end of the elastic part 200 to selectively bite the stick braking protrusion 411 and the braking step 224 is provided. The frame unit 420a is formed in a diagonal shape, And a frame braking protrusion 421 is formed at the upper end of the reel shaft 322 to selectively bite the braking jaw 224 to brake the reel shaft 322.

The bending protrusion guide groove 225 is formed at the lower end of the elastic portion 200 and is inclined in the circumferential direction of the reverse rotation to follow the braking jaw 224.

The coupling protrusion 120 is formed on the lower outer circumferential surface of the winding unit 100 and the locking protrusion 130 is formed on the lower end of the winding unit 100. The coupling protrusion 120 is fixedly coupled to the inner circumferential surface of the elastic unit 200, And a reel shaft 221 is formed at the center of the engaging groove 223. The reel shaft 221 is formed at the center of the engaging groove 223. The reel shaft 221 is formed at the center of the engaging groove 223,

The fixing member 211 is formed at the inner end of the winding springs 210 and is fixed to the locking protrusion 130 at the outer end thereof to fix the winding springs 210 to the winding unit 100. [ And a reel shaft 322 is formed at the center of the lower case 320 so as to penetrate the reel shaft 221. The upper end of the reel shaft 322 is fixed to the upper end of the reel shaft 322, And a fixing groove 323 for fixing and holding the winding springs 210 to the case 300 is formed.

In addition, a PCB contact plate 140b formed in a PCB (Printed Circuit Board) assembling method may be included at the upper end of the rotating shaft 110 where the earphone string 10 is wound in the winding unit 100.

The process of using the present invention will now be described.

1 to 4, the present invention is characterized in that the earphone string 10 is wound around a winding part 100, an elastic part 200 for providing an elastic restoring rotational force to the winding part 100, And a case 300 in which the winding unit 100 and the elastic part 200 are accommodated.

As shown in FIG. 5, a reverse rotation braking unit 400 for selectively braking the reverse rotation of the winding unit 100 is included below the elastic part 200.

In the case of the conventional take-up reel, the earphone cord 10 is kept locked by the locking part when the earphone cord 10 is wound, and an unlocking button is provided on one side of the case 300, The cord 10 is unlocked and wound.

However, according to the present invention, since the reverse rotation braking means 400 for selectively braking the reverse rotation of the winding unit 100 when the earphone string 10 is wound is constituted, the earphone string 10 So that the convenience of the user can be improved.

That is, as one example of the counter-rotating braking means 400, the stick means 410a is fixedly coupled to one side of the stick groove 324, which is positioned halfway from the central axis of the lower case 320, And is caused to flow together with the rotation of the elastic part 200 fixedly coupled to the mounting part 100 and the winding part 100. [

A braking chin 224 is provided at one side of the lower end of the elastic part 200 to selectively engage the winding part 100 only when the winding part 100 is rotated in the reverse direction without being engaged when the earphone string 10 is rotated in the forward direction. And a braking projection guide groove 225 which is formed to be inclined in the circumferential direction of the reverse rotation on the lower end surface and connected to the braking step 224 is formed so that when the winding part 100 rotates in the reverse direction, Is caused to flow along the inclined surface and is guided to the braking step 224.

The stick braking protrusion 411 is moved outwardly from the central axis of the case 300 in the direction opposite to the inclined surface when the winding unit 100 is rotated in the forward direction due to the earphone- So that it can not be guided to the braking chin 224, and even if the braking chuck 224 is moved to the braking chute 224, the braking does not occur and the earphone cord 10 can be unfolded continuously.

On the contrary, when the winding unit 100 is rotated in the reverse direction by winding the earphone cord 10, the stick braking projection 411 flows toward the central axis of the case 300 in the forward direction of the inclined surface, 224 and the latching jaw 224 is engaged.

At this time, when the reverse rotation speed is slowed down, the stick braking protrusions 411, which flow according to the rotation of the take-up part 100, are simultaneously moved by the friction index with the braking protrusion guide groove 225, So that the braking occurs immediately.

On the other hand, if the reverse rotation speed is increased, the stick braking protrusion 411 is not accurately guided to the braking chin 224, so that braking does not occur immediately and the earphone string 10 can be wound continuously.

As the earphone line 10 is continuously wound, the deceleration speed of the rotation speed is reduced by the deceleration friction ball 20 provided on the upper side of the winding unit 100 and the decelerated speed at the end of the earphone line 10 The stick braking protrusion 411 is guided to the braking chin 224 to cause braking.

Similarly, the frame means 420a is also formed with a frame braking projection 421 for allowing the reel shaft 322 to be fixedly coupled to the inside of the frame so as to be able to flow and selectively braking by selectively engaging with the braking jaw 224, The braking protrusion 421 is moved along the braking protrusion guide groove 225 in accordance with the rotation of the take-up part 100, thereby causing braking.

The engaging protrusion 120 is formed on the lower outer circumferential surface of the winding unit 100 and the engaging protrusion 130 is formed on the lower end of the winding unit 100. The engaging protrusion 120 is fixedly coupled to the inner circumferential surface of the elastic unit 200, And a reel shaft 221 is formed at the center of the engaging groove 223. The reel shaft 221 is formed at the center of the engaging groove 223. The reel shaft 221 is formed at the center of the engaging groove 223,

That is, the winding springs 210 for providing an elastic restoring rotational force to the winding portion 100 are formed inside the elastic portion 200.

A coupling protrusion 120 is formed on a lower outer circumferential surface of the winding unit 100 so that an engagement groove 223 is formed in the inner circumferential surface of the elastic part 200 so that the winding springs 210 are fixed To be combined.

A reel shaft 221 is formed in the central portion of the elastic part 200 so that the reel shaft 322 is inserted and inserted.

The fixing piece 211 of the winding spring 210 is fixed to the fixing groove 323 formed at the upper end of the reel shaft 322 so that the winding spring 210 is fixed to the case 300.

The engaging protrusion 130 is formed on the lower end of the winding unit 100 to be engaged with the outer end of the winding springs 210 so that the elastic restoring rotational force of the winding springs 210 So that the winding unit 100 is rotated.

A PCB contact plate 140b formed in a printed circuit board (PCB) assembly manner may be disposed on the upper end of the rotating shaft 110 around which the earphone string 10 is wound in the winding unit 100.
