The reel 150 is rotatably installed by being fixed to the rotary PCB 140 and fitted to the rotary shaft 113 in the reel mounting portion 112 and one side is exposed from the case body 110. The reel 150 is provided with a fixing groove 153 for fixing the rotary PCB 140 and an engaging projection 142 provided at the edge of the rotary PCB 140 is engaged with an engaging groove 154 are rotated together with the rotation PCB 140 so that the winding groove 155 for winding the earphone cable 161 is provided on the periphery and the spring 170 is received on one surface exposed to the outside The receiving groove 156 may be blocked by the cover 151 which is fastened by the bolt 157 to the rotating shaft 113.

The earphone 160 is connected to the rotary PCB 140 so as to be connected to the earphone plug 130 and provided at the end of the earphone cable 161 wound on the reel 150. The earphones 160 may be formed as a pair, but the present invention is not limited thereto. The earphone cable 161 is wound on the reel 150 or wound on the reel 150 according to the direction of rotation of the reel 150 by being wound on the reel 150 of the reel 150, 140 and is connected to an electrode (not shown) provided on the rotary PCB 140 by soldering or the like so as to pass through the cable guide 114 provided on the side of the reel mount portion 112, .

The spring 170 is mounted in the receiving groove 156 formed in the reel 150 and connected to the reel mounting portion 112 so that the earphone cable 161 is wound on the reel 150 Provide resilience. The other end of the spring 170 is fixed to a coupling portion 158 provided in the receiving groove 156 of the reel 150. The other end of the spring 170 is inserted through the rotating shaft 113 The restoring elastic force stored by loosening the earphone cable 161 is transmitted from the rotating shaft 113 to the reel 150 so that the reel 150 is rotated so that the earphone cable 161 is wound.

The stop lever 180 is provided on the reel mounting portion 112 and controls the rotation of the reel 150 by the operation. The stop lever 180 is rotatably mounted on the reel mounting portion 112 and is provided with a locking portion 184 to be engaged with the one directional teeth 152 formed on the rim of the reel 150, The engaging portion 184 is held by the one-way tooth 152 by the elastic force of the spring 182 installed on the earphone 112 so as to suppress the rotation of the reel 150 for winding the earphone cable 161 The reel 150 is pivoted by depression of the pressing portion 183 provided to protrude from the reel mounting portion 112 so that the engaging portion 184 is disengaged from the one directional tooth 152 so as to wind the earphone cable 161 . The stop lever 180 can be hinged to the hinge shaft 116 of the reel mount 112 by the hinge engaging portion 181 formed at the center portion as in this embodiment. At this time, since the fixing piece 116a is forcedly fitted to the hinge shaft 116, it is possible to restrain the stop lever 180 from coming off. 7 and 8, the rotation of the reel 150 is controlled depending on whether the pressing portion 183 is provided or not.

On the other hand, when the reel 150 is rotated in the winding direction of the earphone cable 161, the unidirectional teeth 152 can prevent the reel 150 from rotating due to the engagement with the engaging portion 184, The rotation of the reel 150 is allowed by riding over the latching portion 184 when the cable 161 is rotated in the direction of unwinding the cable 161.

The motion shape portion 190 is represented by a figure that performs motion by using the rotation of the reel 150 on the exposed surface of the reel 150 and the outer surface of the case body 110. When the earphone 160 is detachably attached And has a mounting portion 191 to be mounted. In addition, the motion shape portion 190 may be configured such that the earphone cable 161 is pulled out from the mounting portion 191 and the mounting portion 191 is formed in the case body 110 in the form of a hollow or a groove. In addition, the motion shape portion 190 is represented by a gramophone graphic that performs the reproduction motion of the record by using the rotation of the reel 150 designed as a record as in the present embodiment, and a hollow mounting portion 191 So that when the reel 150 is rotated by the spring 170, the earphone 160 is received in the mounting portion 191 of the speaker design.

As shown in Fig. 10, the motion feature 290 may be represented as a unicycle design that performs rotational motion of the wheel using the rotation of the reel 250, which is designed as a wheel, Shaped mounting portion 291 is provided to allow the earphone 260 to be received in the mounting portion 291 of the saddle-type design when the reel 250 is rotated by the spring. In addition, the motion shape portion can be expressed by various designs such as reels, tops, fans, windmills, aberrations, etc. of a fishing rod that performs rotational motion using the rotation of the reel.

The operation of the earphone-integrated portable device case according to the present invention will now be described.

When the earphone 160 or the earphone cable 161 is pulled to use the earphone 160, the restoring elastic force is stored in the spring 170 and the earphone cable 161 is released from the reel 150, When the force applied to the earphone cable 161 is released, the latching portion 184 of the stop lever 180 to which the elastic force of the spring 182 is applied is inserted into any one of the plurality of unidirectional teeth 152 formed on the reel 150 The rotation of the reel 150 to wind the earphone cable 161 is suppressed in spite of the restoring elastic force of the spring 170. [

When the stopper 180 of the stop lever 180 is pressed so that the earphone cable 161 is wound on the reel 150, the stopper 180 rotates to engage the stopper 184 in one direction The reel 150 is wound around the earphone cable 161 by the restoring elastic force of the spring 170 and the earphone 160 is received or mounted on the mounting portion 191. [ On the other hand, when the force applied to the pressing portion 183 is released, the stop lever 180 is returned by the elastic force of the spring 182 so that the engaging portion 184 is caught by the unidirectional teeth 152 of the reel 150 The rotation of the reel 150 is suppressed.

As described above, the earphone 160 can be stably fixed when the earphone 160 is not used, and the length of the earphone cable 161 can be precisely and easily adjusted. By providing functionality and decorability, .

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
