Description

SLIDING-UP TYPE PORTABLE DIGITAL COMMUNICATION DEVICE AND LOCKING APPARATUS THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to portable digital communication devices, including cellular phones, personal digital assistants (PDAs), hand-held phones (HHPs), and the like, and more particularly, to portable digital communication devices of the sliding-up type.

The term “portable communication device” of a conventional concept refers to an electronic device that a user can carry out wireless communication with a counterpart while carrying. Such portable communication devices have been trending toward miniaturization, slimness, grip, and light weight in consideration of portability, and are moving toward a multi-mediaization direction to pursue more various functions. In particular, more and more portable terminals will be used for miniaturization, light weight, multifunction, and versatility, and will be modified to adapt to various multimedia environments or the Internet environment. In addition, the portable terminal is an electronic device commonly used anywhere in the world, men and women, and is being recognized as a necessity to carry around at all times.

Conventional portable communication devices are classified into various types in appearance. For example, portable communication devices are classified as bar-type, flip-type, or folder-type communication devices depending on their appearance. The bar-type communication device means that the single housing is configured as a 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 is meant that the folder in a single bar-shaped housing is configured to be rotatably connected and folded by a hinge device.

In addition, portable communication devices may be classified into either a neck wearable type or a wrist wear type according to a wearable position or a manner of wearing. A necklace-type communication device refers to a portable method of wearing a terminal around a neck using a string, and a wrist-wear type communication device refers to a portable method of wearing a terminal around a wrist.

In addition, the portable communication device may be classified into a rotation-type or sliding-type communication device according to an opening and closing method. The rotation-type communication device means that the two housings are rotatably connected and opened while remaining facing each other, and the sliding-type communication device means that the two housings are opened and closed by sliding movement in the longitudinal direction. it means. The variously classified communication devices listed above will be readily understood by those of ordinary skill in the art.

In addition, conventional portable communication apparatuses are being converted into structures capable of communicating high-speed data in addition to voice communication functions. That is, as the needs of consumers increase, the service will be provided using a wireless communication technology that transmits high speed data.

Currently, camera lenses have been adopted in conventional portable communication devices, and transmission of video signals and the like has been made. BACKGROUND OF THE INVENTION In general, portable communication devices have been equipped with a camera lens module as an external type or a built-in type to perform a video call with a counterpart or photograph a desired subject.

However, among the conventional portable communication devices, the camera lens employed in the sliding type portable communication device has always been exposed to the external environment so that it is difficult to prevent foreign matter from entering.
