The first cam surface 110 is provided with a stop surface 111 having a small diameter protruding from the stop jaw 112, and the lifting projection 114 is positioned at a position where the lifting guide surface 113 is excavated and divided into four at its periphery. It forms to the height of the stop surface 111 with a triangular projection.

The first cam body 300 is formed to protrude downward by cutting the fixing piece 301 is caught on the stop jaw 112 of the first cam surface 110, and is attached to the bottom surface of the bobbin member 200.

The second cam body 400 is in contact with the stop surface 111 of the first cam surface 110 and the return groove 403 and the stopper hole 402 to which the fixing piece 301 is caught and the fixing piece 301 is inserted. The lock guide surface 401 formed through the hole is formed, and a lifting jaw 406 contacting the lifting guide surface 113 of the first cam surface 110 forms a return guide surface 404 protruding to the bottom surface thereof. In addition, a bottom surface of the stop hole 402 is inclined to form a slide surface 405 for leaving the stop jaw 112 of the first cam surface 110 when the stop is released.

According to the present invention having such a configuration, the wire 501 of the ear microphone 500 is wound around the bobbin member 200 that is elastically reeled 202 in the assembled state as shown in FIG. 3. At this time, when the mobile phone is received, the user inserts the plug 503 of the wire into the earphone jack hole of the mobile phone (not shown) to make an electrical connection, or the speaker unit while the earphone plug 503 is already plugged into the mobile phone. 502 is grasped and pulled in the A direction shown in Fig. 7A.

However, when the fixing piece 301 of the first cam body 300 is caught by the return groove 403 as shown in FIG. 7C, the elasticity of the reel spring 202 is transmitted to the second cam body 400 to raise and lower the jaw of the return guide surface 404. 406 is a state in which the second cam body 400 is lifted from the lower cap 102 by the inclined surface of the lifting projection 114 of the lower cap 102, and at the same time the diameter of the second cam body 400 Since the photo slide surface 405 rides on the stop jaw 112 of the first cam plane 110 and rises as shown in FIG. 7E, the second cam body 400 continues to rotate in reverse. The lock state is not maintained. Therefore, when the wire 501 is pulled again as the first time, the return guide surface 404 of the second cam body 400 descends along the lifting guide surface 113 of the first cam surface 110 as shown in FIG. 7E, and the lifting jaw 406. ) And the lifting projection 114 are interlocked to achieve the action of stopping the second cam body 400, and only the first cam body 300 is rotated so that the fixing piece 301 is released from the return hole 403, and then as shown in Figure 7a. It becomes a state that is inserted into the stop hole 402 of the second cam body 400 is engaged with the stop jaw 112 protruding from the first cam surface 110 of the lower cap 102 to achieve a lock state.

In this state, the user can talk to the other party without holding the mobile phone. To wind the wire 501 of the ear microphone 500 drawn after the call, hold the wire and pull it slightly in the withdrawal direction. As shown in FIG. 4, the bobbin member 200 and the first cam body 300 simultaneously rotate elastically and the fixed piece. 301 is removed from the stop hole 402 of the second cam body 400 is inserted into the return groove 403 formed in the lock guide surface 404 is caught. When the user releases the wire 501 in such a state, the resilience of the reel spring 202 returns to move the bobbin member 200, the first cam body 300, and the second cam body 400 in the B direction. At this time, the inclined lifting jaw 406 protruding from the return guide surface 401 of the second cam body 400 is lifted on the inclined lifting guide surface 113 of the first cam surface 110 to lift the second cam body 400. Lifted and the inclined slide surface 405 of the return guide surface 404 formed on the bottom surface of the stop hole 402 of the second cam body 400 rides on the vertical stop surface 111 of the first cam surface 300. Since the locked state is released by moving, the wire 501 of the ear microphone 500 acts to wind all of the bobbin members 200, so that the speaker part 502 and the plug are outside the protective case 100. Only the part 503 remains.

As described above, the present invention is provided with a bobbin that rotates, a cam surface that locks and unlocks between the upper and lower caps that do not rotate, and a cam body, and a resilient contact terminal to stably provide electricity in a rotated and stopped state. With the configuration, the wire can be drawn out to the required length and locked in a stable state.After use, the wire is wound by the action of elastically disconnecting and releasing the wire, eliminating coarseness, and preventing the wire from twisting and breaking. This has the advantage.
