By fundamentally eliminating the problem of overlapping and by dispersing and absorbing the concentrated stress generated during spring operation at both ends, it is possible to make the portable terminal ultra slim according to the reduction of the thickness of the sliding device and to improve the durability and the slide operation. In addition to improving the shape of the guiding guide member, slide-type portable parts that can maintain smooth and smooth operation during slide operation by applying coating and film materials, as well as conventional guide rails made of plastic, which can minimize the coefficient of friction. It relates to a sliding device of the terminal.

In general, a portable terminal is a wireless communication device that allows a user to carry a hand or carry a body while making a call.

These portable terminals have been released with various functions and designs to meet the needs of users.

For example, a bar type in which a button is exposed to the outside, a flip type and a folder type in which a cover for protecting a button is provided, and a cover in which a display unit is mounted from a main body equipped with a key input unit. There is a slide type (slid type) is a slide operation.

Recently, as the design of portable terminals is diversified, there is a growing demand for slide type portable terminals that are convenient in terms of operability and handling.

Usually, the slide-type portable terminal includes a main body equipped with a key input unit, a cover equipped with a display unit, and a sliding device for mediating a sliding operation between the main body and the cover, wherein the sliding device includes a fixed plate fastened to the main body side; The slide plate is fastened to the cover side and is slidable with respect to the fixed plate, and is interposed between the fixed plate and the slide plate is composed of a spring member and the like to enable the elastic movement of the slide plate, that is, the elastic opening and closing of the cover.

In particular, in the case of a slide-type portable terminal, the cover opening / closing method includes a manual slide by a user manually, a combination using a rack and pinion, and a semi-automatic type using a spring member. Due to its simple structure and low manufacturing cost and ease of use, the semi-automatic type using the spring member is getting a great response from consumers.
