BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to portable devices including cellular phones, personal digital assistants (PDAs), hand-held phones (HHPs), camera phones, DMB phones, and the like. To provide a device.

The term "portable device" in a conventional concept refers to an electronic device that a user can carry and perform wireless communication with a counterpart. Such portable devices are becoming smaller, slim, grip, and lighter in consideration of their portability, and are moving toward a multi-media direction in which various functions can be pursued. 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.

BACKGROUND OF THE INVENTION Conventional portable devices are classified into various types in appearance. For example, portable devices are classified as bar-type, flip-type, or folder-type communication devices according to 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 devices may be classified into either a neck wearable type or a wrist wear type according to a body wearing position or a wearing manner. 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, portable devices may be classified as rotation-type or sliding-type communication devices according to the 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 devices 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.

At present, the camera lens is adopted in the conventional portable device and the transmission of the video signal and the like is in progress. BACKGROUND OF THE INVENTION In general, portable devices are equipped with a camera lens module externally or internally so that video call with a counterpart or photographing a desired subject can be performed.

However, the conventional portable device has the following problems. In the future, when a multimedia environment arrives, a mobile device must have a variety of modes of service, and in consideration of this, a conventional mobile device may not provide an optimal interfacing environment to a user in a more converged multimedia environment. . For example, a conventional portable device may be a device faithful to one mode, specifically, a device for convenient voice call, a device for camera shooting, or a device for text transmission, but is suitable for the three modes simultaneously. There is a disadvantage in that it does not provide an interfacing environment, that is, a data input / output environment.

In particular, with the advent of DMB media environment, the liquid crystal display device most often used as a data output device should be provided with an environment in which it is placed in a horizontal view state. There is a requirement that the environment be provided.

Accordingly, an object of the present invention is to provide a portable device capable of actively responding to a multimedia environment.
