The present invention relates to a sliding module of a sliding type portable terminal that facilitates the opening and closing operation of the sliding type housing.

In general, the term “portable communication device” refers to a device that a user can carry and perform wireless communication with a counterpart. Such portable communication devices are classified into various types in appearance. For example, portable communication devices are classified into bar-type, flip-type, or folder-type terminals according to their appearance. The bar-type terminal means that the single housing is configured as a bar-type, the flip-type terminal means that the bar-type housing and the flip is rotatably coupled by the hinge device, the folder-type terminal is a single It is meant that the folder in the bar-shaped housing is rotatably connected by a hinge device and configured in a folding manner.

In addition, portable communication devices may be classified as either rotation-type or sliding-type wireless terminals according to the switching method. The rotatable terminal means that the two housings are rotatably connected and opened in a facing state while facing each other, and the sliding-type terminal means that the two housings are opened and closed in a facing state with longitudinal movements. The variously classified portable communication devices listed above will be readily understood by those of ordinary skill in the art.

1 to 5, when the sliding type portable terminal 1 is viewed based on the main body 2 provided with a plurality of keypads 2a and a microphone device 2b, the sliding body 3 is the main body. It can be configured to be opened by sliding to the lower side or the upper side to about 1/2 of the length of the body (2), generally 3x4 keypad can be installed on the main body (2), on the front of the sliding body (3) An auxiliary keypad composed of an arrangement of a plurality of auxiliary keys, a speaker device 3a and a display device 3b can be provided.

3 and 4, the conventional sliding type portable terminal 1 includes a main body 2, a sliding body 3 slidingly moved by a predetermined length on the main body 2, and the main body 2.
