Description

Portable communication device {PORTABLE COMMUNICATION DEVICE}

The present invention relates to a portable communication device configured to be rotatable or sliding movable.

In general, the term “portable communication device” refers to an electronic device that a user can carry and perform wireless communication with a counterpart. Various types of service contents such as voice call service, short message transmission, mobile banking, TV watching, online game, video on demand, etc. are provided to the user through a portable communication device.

Conventional 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, and sliding-type communication devices according to their appearance. . The bar-type communication device means that the single housing is configured as the bar-type, the flip-type communication device means that the flip is rotatably configured by the hinge device in the bar-type housing, the folder-type communication device is It means that the folder in a single bar-type housing is configured to be rotatably connected and folded by a hinge device.

In addition, the sliding-type communication device means that the two housings are opened and closed by sliding movement in the longitudinal direction. The variously classified communication devices listed above will be readily understood by those of ordinary skill in the art.

In addition, the configuration of the sliding type portable communication device is disclosed in detail in Patent Application No. 2002-71911 filed by the present applicant. The sliding type portable communication device disclosed in the previously disclosed patent application No. 2002-71911 has a structure in which the housing is slid in only one direction while the two housings face each other and is open to about 1/2 of the fixed housing length. Since the entire area of the terminal cannot be used, there is a problem of restricting the installation of the keys and the liquid crystal display.

In addition, the folder-type portable communication device has a disadvantage in that it does not give the user a pleasure because of one operation because the folder is simply opened and closed in one way by rotating the folder from the main housing by the hinge device.

Therefore, there is a need for a portable communication device that is opened or closed by a sliding type or a folder type.
