The present invention relates to a mobile communication terminal including a DMB phone, a game phone, a chat phone, a camera phone, an MP3 phone, a cellular phone, a PCS, a personal digital assistant (PDA), a hand-held phone (HHP), and the like. In particular, the present invention relates to a biaxial rotating folder type mobile communication terminal which provides an optimal user interfacing environment by selectively changing a folder opening and closing type.

A mobile communication terminal refers to an electronic device that a user can carry and wirelessly communicate with a counterpart. Examples of wireless communication include voice call, message transfer, file transfer, video call, camera function, and the like. In addition, the portable communication terminal will perform the role of a personal assistant such as telephone number management, gain schedule management, and the like.

In addition, mobile communication terminals are becoming smaller, slim, grip, and lighter in consideration of portability, and include multimedia directions for pursuing more diverse service functions, for example, entertainment including games and entertainment. It is moving toward the importance of content. In the future, mobile terminals are expected to change into a multifunctional complex trend that includes not only voice calls but also video calls, games, the Internet, cameras, and the like.

Conventional mobile communication terminals are classified into bar-type or folder-type communication devices according to their appearance in consideration of portability and ease of use. Bar-type communication device refers to a configuration in which a single housing is configured as a bar-type, and is equipped with a data input / output device, an antenna device, a transceiver, etc., and a folder-type communication device is a folder hinged device in a single bar-type housing. By means of rotatably connected is configured in a folding manner.

For example, a folder type mobile communication terminal has a structure in which a folder is rotatably coupled to a main body by a hinge part, keys are arranged on the main body side, and a display part is arranged on the main body side, which is advantageous in miniaturization and portability. There is this. The folding portable communication terminal is disclosed in US Patent No. 6,865,406. In US Patent No. 6,865,406, a camera lens housing is mounted and used at the hinge portion of a folding portable communication terminal.

However, the conventional mobile communication terminal is not inconvenient for data input operation or displayed data confirmation in a phone mode such as voice call or simple text message transmission. However, in an increasingly multimedia environment, for example, in a complex text transmission mode, The speed and accuracy of data input operation and key presses are reduced, data input operation is cumbersome, and a wide screen is not provided on the display unit.

Of course, if the overall size of the mobile communication terminal is equipped with a wide display unit and more keys are disposed, the above-mentioned problems can be overcome. However, there is a problem that it is counter to miniaturization.

Accordingly, there is a need for a foldable mobile communication terminal having the same overall size as the conventional one and convenient to use not only in the phone mode but also in the QWERTY mode for inputting complex data.

Accordingly, an object of the present invention is to provide a convenient mobile communication terminal by selecting the opening and closing method according to the mode change.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

1 to 8, the mobile communication terminal according to the present invention is a terminal in which the hinge unit 300 is deformed by changing the first hinge axis A1 in one swing operation, thereby changing the opening / closing type of a folder. The folder 200 may be folded by being rotated about the first hinge axis A1 facing in the horizontal direction in the main body 100, or may be folded by being rotated around the first hinge axis A1 facing in the vertical direction. Consists of the configuration. Of course, since the main body 100 and the folder 200 are configured in a shape corresponding to each other, the folder 200 opens and closes the entire upper surface of the main body 100. The opening / closing operation of the two types of folders 200 is selectively performed by the user and is selected according to the mode conversion. 1 to 4, the state in which the folder 200 is folded or unfolded about the first hinge axis A1 is shown. In FIGS. 5 to 8, the folder 200 is rotated 90 degrees. The folded or unfolded state about the hinge axis A1 is shown.

Specifically, the mobile communication terminal according to the present invention moves in the horizontal direction or the vertical direction in the main body 100 and the main body 100 by the deformation of the first hinge axis (A1) on the main body 100 The folder 200 that is folded or unfolded on the main body 100 and the folder 200 are rotatably connected about the first hinge axis A1 in a direction closer or farther from the main body 100. The rotating hinge 300 is configured to change the hinge axis A1 of the folder 200 in one swing motion along the outer circumferential surface of the main body. The opening / closing type of the folder 200 is dependent by the rotation hinge part 300.

The rotating hinge part 300 is a rotating device that mechanically connects the main body 100 and the folder 200. The rotating hinge part 300 connects the first hinge axis A1 and the second hinge axis A1 to be described later. In addition to providing a semi-automatic drive source. In addition, the rotation hinge part 300 may be swinged and disposed on one side surface of the main body 100 or the folder 200 or the other side area adjacent to or opposed to the one side. 1 to 4 illustrate the case in which the rotating hinge part 100 is disposed on one side of the main body 100, and a case illustrated on the other side of the main body 100 is illustrated in FIGS. 5 to 8.
