The present invention relates to a slide type portable terminal having a structure slidable along a plurality of different directions.

A portable terminal is a portable device that is portable and has one or more functions such as voice and video call function, information input / output function, and data storing function.

As the functions of the portable terminal are diversified, for example, the portable terminal has complicated functions such as photographing and photographing of a moving picture, reproduction of music or video file, reception of a game and broadcasting, and is implemented as a multimedia device .

In order to implement complex functions in multimedia devices, various new attempts have been made in terms of hardware or software. For example, a user interface environment is provided for a user to easily and conveniently search for or select a function.

In addition, a portable terminal is regarded as a personal portable product for expressing its own personality, and various designs are required. The portable terminal generally has a structure such as a bar type, a folder type, a slide type, a swing type, and a swivel type.

Among the above-mentioned structures, the slide type portable terminal generally has a structure in which two bodies are arranged to overlap with each other and relatively slide along one direction.

In recent years, various attempts have been made to provide a structure for providing a more convenient user interface to a user as well as the above structure of a portable terminal.

The present invention provides a slide module for relative sliding movement of bodies along a plurality of directions, the slider module having a slim thickness.

According to an aspect of the present invention, And a second body connected to the first body by a slide module and sliding along a first or second direction having different directions in a closed state, the slide module being fixed to the first body, A first slide member having first and second rail portions that respectively follow the first and second directions; And a second slide member fixed to the second body and sliding along the first or second rail portion.

The first slide member includes a support portion supporting the second slide member in a closed state; A first extension portion having the first rail portion and extending from the support portion toward the first direction; And a second extension portion having the second rail portion and extending from the support portion toward the second direction.

The slide module may further include a support member extending from the first and second rails to the support portion and supporting the second slide member to prevent the second slide member from tilting in a closed state.

The present invention provides a structure in which a second slide member is slidably coupled to a first slide member having first and second rails, thereby realizing a slide module having a slim thickness.

Further, by providing a magnetic force providing portion in the slide module, the semi-automatic structure of the slide module can be realized slimly and the reliability of the slide module can be improved.

As shown in FIG. 1, a state in which the first body 10 is disposed so as to overlap with the second body 20 may be referred to as a closed configuration. As shown in FIGS. 2 and 3, The state where the first body 110 exposes at least a part of the second body 120 may be referred to as an open configuration.

FIG. 2 shows that the second body 120 is slid along the first direction X, and FIG. 3 shows that the second body 120 slides along the second direction Y. FIG. Hereinafter, the state of FIG. 2 is referred to as a first open state, and the state of FIG. 3 is referred to as a second open state.

The mobile terminal operates mainly in the standby mode in the closed state, but the standby mode is also released by the user's operation. The portable terminal operates mainly in the communication mode in the open state, but is also switched to the standby mode by the operation of the user or a predetermined period of time.

The casing (housing, housing, cover, etc.) constituting the outer appearance of the first body 110 is formed by the front case 111 and the rear case 112. Various electronic components are embedded in the space formed by the front case 111 and the rear case 112.

At least one intermediate case may be additionally disposed between the front case 111 and the rear case 112.
