The present invention relates to a portable terminal comprising a dual connection member for rotating a liquid crystal display and a keypad of the portable terminal.

In general, the term “portable terminal” refers to a device that a user can carry and perform wireless communication with a counterpart. Such portable terminals are classified into various types in appearance. For example, portable terminals 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, the portable terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing 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 terminals listed above will be readily understood by those of ordinary skill in the art.

In the above-mentioned various types of conventional portable terminals, the light and simple terminals have become mainstream, so that they are convenient to carry.

Although mobile communication services are gradually diversified and the multimedia devices of the portable terminals have been diversified, the portable terminals have not escaped the conventional foldable and sliding terminals. In addition, as the use of the portable terminal is becoming more common, the taste of the user is also diversified, but the form of the portable terminal does not satisfy various tastes of the users.

In order to solve the above disadvantages, a display rotatable mobile terminal has been developed.

The display rotatable mobile terminal rotates a display device of a folder to watch a video and a video so that a wide screen can be viewed.

However, the conventional display rotatable portable terminal simply rotates the display device of a folder to watch a video and a video, but when the user uses the keypad provided in the main body when using the game mode function, the user has a keypad provided in the vertical direction. It was inconvenient to use.

In addition, in the conventional display rotating portable terminal, when a hinge axis of a folder is provided at the center of the folder to rotate the folder about the hinge axis, a predetermined space is formed between the folder and the main body of the terminal. The constant space is always generated during folder rotation, increasing the size of the terminal and acting as a deterrent to miniaturization.

Accordingly, the present invention is to solve the above-mentioned conventional problems, an object of the present invention, by configuring a dual connection member for rotating the liquid crystal display unit and the keypad of the portable terminal, the liquid crystal display unit and It is to provide a portable terminal having a dual connection member to improve the use of the terminal by rotating the keypad.

Another object of the present invention is to configure a dual connection member for rotating the liquid crystal display and the keypad of the portable terminal, and to configure the hinge axis to be eccentric and movable to position the liquid crystal display and the keypad in close proximity to each other to enhance the ease of use of the terminal The present invention provides a portable terminal having a dual connection member capable of miniaturizing the terminal by reducing unnecessary space generated during conventional rotation.

In order to achieve the above object, the present invention provides a portable terminal,
