Description

Portable communication device {PORTABLE COMMUNICATION DEVICE}

TECHNICAL FIELD The present invention relates to a portable communication device, and more particularly, to a multipurpose portable communication device that is opened and closed by a sliding type.

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, wireless terminals are classified as bar-type, flip-type, or folder-type wireless terminals according to their appearance. Bar-type wireless terminal means that the single housing is configured in the bar-type, flip-type wireless terminal means that the flip or cover is rotatably configured by the hinge device in the bar-shaped housing, folder-type wireless The terminal means that the folder is configured to be rotatably connected to the single bar-shaped housing by a hinge device and to be folded.

In addition, the mobile terminal may be classified into a neck wearable type or a wrist wear type according to a body wearing position or a wearing method. A necklace-type wireless terminal refers to a portable method of wearing a terminal around a neck using a string, and a wrist-type wireless terminal refers to a portable method of wearing a terminal to a wrist.

In addition, the wireless terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. Rotational-type wireless terminal means that the two housings are rotatably connected to open and close facing each other, the sliding-type wireless terminal is one of the two housings, one of the housing facing the longitudinal sliding movement It means to open and close. The variously classified wireless terminals listed above will be readily understood by those of ordinary skill in the art.

Meanwhile, the above-mentioned conventional portable terminals are essentially provided with an antenna device, a data input / output device, and a data transmission / reception device. Of course, the data input device is commonly used as a keypad for inputting data mainly by a finger pressing operation, a touch pad or a touch screen is also used. In addition, the data output device commonly uses an LCD.

In general, a keypad used for data input consists of an arrangement of a plurality of keys. These keys consist of numeric keys, letter keys, send keys, end keys, function keys, and the like. In addition, the keys are usually arranged in place in the number of about 15 to 20 on the upper surface of the housing of the portable terminal. Of course, the keys are exposed from the upper surface so that the user inputs the desired data by pressing a finger. In addition, the conventional portable communication device for the video call is provided with a camera lens, the camera means, through which a video call with the other party, it is possible to shoot a desired subject.

However, more and more users are increasingly in need of informatization, and in reality, it is very inconvenient when the conventional portable terminal is used for communication under the Internet or multimedia environment. In particular, the LCD, which is a data output means, is generally fixedly mounted or rotatably mounted in one direction, which causes a problem that an uncomfortable posture is required from a user's point of view.

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

Another object of the present invention is to provide a portable communication device that is convenient for use.

In order to achieve the above object, the present invention provides a main housing including a keypad of a predetermined position on the upper surface and a keypad composed of an array of a plurality of keys spaced apart from the speaker device, and opening and closing by sliding movement in the longitudinal direction in the main housing.
