The present invention relates to a sliding type mobile phone, and more particularly, to a sliding device of a sliding type mobile phone for slidably coupling the sliding part from the main part to the vertical direction. The present invention also relates to a slim sliding type mobile phone having the slide device.

Mobile phones are preferred for their small size because their primary purpose is to carry them, and they prefer to have a special design or include a variety of functions. Therefore, referring to the mobile phones that are released these days, small and thin products are continuously released, and lighter and better design products are popularly sold in the market.

Mobile phones are generally classified into flip type, folder type and sliding type according to their appearance and operation method. The current mainstream is sliding type mobile phones.

The sliding cell phone refers to a cell phone in which a main part and a sliding part are overlapped with each other, and a display part and a key input part face the same direction in each part. In general, the sliding type mobile phone may slide the front sliding part relatively to expose the display unit or the key input unit that is hidden on the rear side. For example, there is a mobile phone that can push up the front sliding part to expose the key input unit formed on the front of the main part of the rear. In addition, there is also a mobile phone that can expose the display formed on the front of the main part of the rear by moving the sliding part of the front in which the key input unit is formed downward.

Korean Utility Model Registration No. 20-319967 describes a 'slide type portable wireless terminal'. As shown in FIG. 1, the slide apparatus of this technology includes a main plate 110 coupled to a main part, a slide plate 120 sliding along a main plate 110, and a sliding of a slide plate 120. It comprises a torsion spring 130 that provides a torsion upon movement.

The slide apparatus of this technique is formed in a plate shape so as to be joined to the rear surface of the sliding part, and has a sliding plate having protrusions on both sides, a pair of moving rails respectively joined to the protrusions of the sliding plate, and the front part of the main part. It comprises a hinge plate, a pair of rail guides joined to the upper surface of the hinge plate corresponding to the position of the moving rail, and a pair of torsion springs connecting the sliding plate and the hinge plate to each other.

However, the techniques are configured to have a guide groove on one plate and a guide portion guided along the guide groove on the other plate so that the slide plate is slidably movable relative to the main plate. That is, the techniques are configured to slide the guide portion is inserted into the guide groove. However, since the guide groove and the guide portion are formed by deforming a portion of each plate by bending or the like, and are formed of the same material, smooth sliding is not possible due to friction between the same materials.

In addition, since the above techniques do not include a stopper for limiting the sliding movement range of the slide plate, a modification is required to separately form an upper and lower stopper in the mobile phone to limit the movement of the slide plate to the upper and lower portions thereof. Therefore, there is a limit in making the phone thin and slim. In addition, the techniques are configured to expose a portion of the main plate to the back of the mobile phone when the slide plate slides up with respect to the main plate to use the mobile phone. Therefore, there is a disadvantage in that the manufacturing cost increases because the aesthetics of the mobile phone must be considered, such as plating the main plate or designed to have a good shape.
