The present invention relates to a slide up opening and closing device for a communication terminal, and more particularly, to a slide up opening and closing device for a communication terminal for opening the slide body inclined at a predetermined angle with respect to the main body.

In recent years, communication terminals have been widely used according to the development of wireless information communication technology. In addition to the inherent functions of simple wireless communication, additional functions suitable for the user's taste are required for such communication terminals.

According to such a demand, communication terminals are known from a general bar type, a flip type, a folder type, and the like.

Among these various types of communication terminals, a folder type terminal and a slide type terminal that can contribute to miniaturization of a terminal while having a display device having a wide LCD module are mainly used these days.

In the slide type communication terminal, the slide body is opened and closed by a sliding operation on the main body.

In a typical slide type communication terminal, the main body is provided with a guide groove, and the slide body is provided with a roller or a slide protrusion for sliding along the guide groove, and when the slide body is pushed to one side, the slide body moves along the main body. When the terminal is opened to be used while moving in a straight line and the slide body is pushed in the opposite direction when the slide body is opened, the slide body is closed while the slide body is linearly moved along the main body.

However, such a conventional slide type communication terminal has a structure in which the slide body moves in a straight line, so that the slide body is opened in a straight shape, which causes inconvenience in using the terminal.

That is, since the transceiver of the communication terminal is not suitable for the angle between the mouth and ears of the person it is inconvenient to use and call quality may be degraded.

In addition, there is an inconvenience in use even when a display or a touch screen is adopted in the communication terminal.

Meanwhile, Korean Unexamined Patent Publication No. 2005-0056609 discloses a "slide up type portable terminal".

15 and 16, the portable terminal according to the related art includes a main body 2, a slide body 4 that is opened and closed by sliding to one side along the main body 2, and the main body 2. And an angle maintaining member 6 installed between the slide body 4 and the one side of the slide body 4 when the slide body 4 is opened.

A pair of slots 18 are provided on both sides of the front surface of the main body 2, and slide projections 20 that slide along the slots 18 are formed on both sides of the rear surface of the slide body 4.

However, in the case of the slide-up type portable terminal, an operation of moving the angle holding member along the guide groove in opening the terminal may not be performed smoothly, and it is inconvenient for the user to apply force until the slide body is completely opened. There is this.

In addition, when the end portion of the slide body moves along the slide protrusion, the main body may not be opened smoothly. That is, since the slide body is inclined while being opened, the end of the slide body may press the main body to prevent the sliding movement of the slide body.

On the other hand, when the wide display is adopted, the operation unit excluding the display must be provided on the main body. In the case of the slide-up type portable terminal, the slide body opens very little in a limited width, and therefore, the operation unit must be integrated in a limited area of the main body. This may cause difficulties in the manufacturing process, or may be inconvenient to the user according to the miniaturization of the operation unit.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is that the slide body is opened inclined at a predetermined angle with respect to the main body to open by itself without applying a force after opening to some extent. It is to provide a slide-up opening and closing device for a communication terminal that can provide convenience.
