The term "mobile communication device" in a conventional concept refers to an electronic device that a user can carry and perform wireless communication with the other party. Such portable communication devices have been trending toward miniaturization, slimness, grip, and light weight in consideration of portability, and are moving toward a multi-mediaization direction to pursue more various functions. In particular, more and more portable communication devices will be used for miniaturization, light weight, multifunction, and versatility, and will be modified to adapt to various multimedia environments or the Internet environment. In addition, the portable communication device is an electronic device commonly used anywhere in the world, men and women, and is being recognized as a necessity to carry around at all times.

Conventional portable communication devices are classified into various types in appearance. For example, portable communication devices are classified into bar-type, flip-type, or folder-type communication devices according to their appearance. The bar-type communication device means that the single housing is configured in the bar-type, the flip-type communication device means that the flip is rotatably configured by the hinge device in the bar-type housing, It is meant that the folder in a single bar-shaped housing is configured to be rotatably connected and folded by a hinge device.

In addition, the portable communication device may be classified into a neck wearable type or a wrist wear type according to a body wearing position or a wearing manner. A necklace-type communication device refers to a portable method of wearing a communication device on a neck using a string, and a wrist-wear type communication device means a portable method of wearing a communication device on a wrist.

In addition, the portable communication device may be classified into a swing-type or a sliding-type communication device according to an opening and closing method. The swing-type communication device means that the two housings are rotatably connected and opened while remaining facing each other while the sliding-type communication device means that the two housings are opened and closed by sliding movement in the longitudinal direction. it means. The variously classified communication devices listed above will be readily understood by those of ordinary skill in the art.

In addition, conventional portable communication apparatuses are being converted into structures capable of communicating high-speed data in addition to voice communication functions. That is, as the needs of consumers increase, the service will be provided using a wireless communication technology that transmits high speed data.

Currently, a camera lens is adopted in a conventional portable communication device, and transmission of video signals and the like is in progress. The universal mobile communication device has an external or internal camera lens module to perform a video call with a counterpart or photograph a desired subject.

The folder 20 has a top surface 20a of which is formed as a planar surface, and a first speaker device 210 and a first speaker neighboring the first speaker device 210 on its bottom surface 20b. And a display unit 214. At this time, the folder 20 rotates about a third hinge axis A3 facing in the vertical direction with respect to the first and second hinge axes A1 and A2, respectively. That is, the folder 20 may be referred to as a "three-axis hinge folder" because it is rotatable about the first, second, and three hinge axes A1, A2, and A3, respectively. The folder 20 is configured to be rotatable about the third hinge axis A3 so that its upper surface 20a or lower surface 20b can be inverted by the user.

Therefore, as shown in FIG. 7 after the folder 20 is rotated about 90 degrees in FIG. 6, when the folder 20 is rotated about the third hinge axis A3, the camera 20 is in the camera photographing mode. The captured image may be captured while watching the first display device 212. For reference, the amount of rotation by the first hinge axis A1 of the folder 20 is between 0 degrees and about 150 degrees, and the amount of rotation by the second hinge axis A2 of the folder 20 is 0 degrees. It is about 90 degrees, and the rotation amount by the 3rd hinge axis A3 of the said folder 20 is about 0 degrees-about 180 degrees.

In this case, the folder 20 may be rotated about the third hinge axis A3 without being interfered only when the folder 20 is opened at a predetermined angle or more about the first hinge axis A1.

Accordingly, the user may photograph the subject when the camera lens 314 is open.

For reference, when the folder 20 is to be rotated about the first hinge axis A1, the user may locate the second hinge device 50 and the auxiliary unit located on the bottom surface 10b of the main housing. Holding the lower surface 30b of the housing and performing the opening and closing operation will be in a state as shown in FIG. 5. On the other hand, if the folder 20 is opened without holding the lower surface of the auxiliary housing around the second hinge axis A2, the same state as in FIG. 6 is obtained. Then, the folder 20 is connected to the third hinge. When it rotates about 90 degrees about the axis A3, it will be in the state like FIG.

In addition, it should be noted that the direction of rotation may be reversed by the third hinge axis of the folder. That is, although the first display device 212 of the folder 20 is shown to face in the opposite direction of the camera lens 314 module in FIG. 7, the first display device 212 is the camera lens module 314. It should be noted that it can be rotated about the third hinge axis (A3) toward the (). When the first display device 212 is disposed in a direction opposite to the camera lens 314, it is convenient for photographing a desired subject, and the first display device 212 rotates toward the camera lens 314. In this case, the user may take a picture of his or her face or perform a video call with the other party while watching the first display device 212.
