The present invention relates to a hinge device for a display rotatable mobile terminal that constitutes a hinge module having a plate shape for rotating the display device in a forward and reverse direction in the display rotatable mobile terminal.

In general, the term “portable communication device” refers to a device that a user can carry and perform wireless communication with a counterpart. Such 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 terminals according to their appearance. The bar-type terminal means that the single housing is configured as a bar-type, the flip-type terminal means that the bar-type housing and the flip is rotatably coupled by the hinge device, the folder-type terminal is a single It is meant that the folder in the bar-shaped housing is rotatably connected by a hinge device and configured in a folding manner.

In addition, portable communication devices may be classified as either rotation-type or sliding-type wireless terminals according to the switching method. The rotatable terminal means that the two housings are rotatably connected and opened in a facing state while facing each other, and the sliding-type terminal means that the two housings are opened and closed in a facing state with longitudinal movements. The variously classified portable communication devices listed above will be readily understood by those of ordinary skill in the art.

In the above-mentioned various types of conventional portable communication devices, a light and simple terminal has become mainstream for convenience of carrying, and there is a disadvantage in that it is particularly convenient only during a voice or video call with the other party.

1 to 3, the conventional display rotatable portable terminal includes a main body housing 10 having a first hinge shaft A1 at one end, a folder 20, and a connecting member 30. The key housing 11 and the microphone 12 are mounted to the main body housing 10. The connecting member 30 connects the body housing 10 and the folder 20, and the folder 20 in a direction closer to or away from the body housing 10 about the first hinge axis A1. Makes it rotatable. In addition, the connecting member 30 is provided with the second hinge axis, and the folder 20 is rotatably connected in a state facing the connecting member 30 along the second hinge axis A1, The folder 20 includes an LCD 21 and a speaker 22 as a display device.
