The present invention relates to a slide type portable terminal, and more particularly, to a slide type portable terminal that can substantially reduce the overall thickness of the terminal by simplifying a mechanism for sliding the terminal body.

A portable terminal including a mobile communication terminal or a PDA is one of electronic devices that allow a user to view or process wireless transmission and reception or information using the mobile terminal while using the mobile terminal.

One of the basic directions in designing a portable terminal would be to have a small enough size and light mass so as not to interfere with portability, but each component or device must be efficiently arranged to provide various functions. This means that small, high-density parts should be used instead of parts that occupy a large space, and parts should be properly arranged to reduce unnecessary or wasted space.

Various types have been proposed as a mechanical form of a portable terminal for achieving such a design goal. For example, the slide type, the folder type, or the so-called swivel type.

Among them, the slide-type portable terminal is preferred because the display device is directly exposed to the outside of the terminal, which not only can receive information in a short time, but also has the advantage that the operation for opening the mechanism is simple and easy to use.

Also in the development of such a slide-type portable terminal, the main concern is how much the thickness of the terminal can be reduced. Conventional slide-type portable terminals have a form of additionally installed between the body and the body to slide the so-called 'slide module' assembly (refer to Figs. 1 and 2)

1 and 2 are examples of the prior art, each of which shows a schematic longitudinal section of a slide-type portable terminal divided before and after assembly.

As shown in FIG. 1, the portable terminal 110 is slidably moved with respect to the display unit 120 under the display unit 120 and the display unit 120, and is mounted to be opened and closed with respect to the display unit 120. And a slide module 140 installed between the display unit 120 and the terminal body 130 to guide the display unit 120 to the terminal body 130 to be slidable. .

The slide module 140 is fixed to the display unit 120 and is installed to be slidably moved with respect to the first slide member 150 and the first slide member 150 that are integrally moved with the display unit 120. The second slide member 160 is fixed to the 130 and moved integrally with the terminal body 130.

By such a configuration, when the first slide member 150 is moved relative to the second slide member 160, the first slide member 150 and the fixed display unit 120 are also moved together to display the display unit 120. The terminal body 130 is opened and closed.

However, since the slide module 140 is mounted on the conventional slide type portable terminal to implement the slide operation, the thickness T that cannot be mounted between the display unit 120 and the terminal body 130 is not possible. Occurs. The thickness T is formed by the sum of the thickness of the lower surface of the display unit 120, the thickness of the upper surface of the terminal body 130, and the thickness of the slide module 140.

In order to reduce the thickness T, first, there is a method of reducing the thickness of the slide module 140, but the space 141 inside the slide module 140 connects the display unit 120 and the terminal body 130 to each other. Since the FPCB 170 passes, there is a limit in reducing the thickness of the slide module 140 itself. This is due to the fact that the FPC 170 must secure an active space even during the slide movement of the first slide member 150 and the second slide member 160.

Next, when reducing the thickness of the rear surface of the display unit 120 or the thickness of the front surface of the terminal body 130, there is a problem that can not be reduced indefinitely in that it can lower the reliability of the product due to the degradation of the strength.
