Generally, the term "portable terminal" means a device capable of carrying out wireless communication with the other party while the user is carrying it. These portable terminals are classified into various types in an outer shape. For example, the portable terminal is classified into a bar-type, a flip-type, or a folder-type according to the external appearance. A bar-type terminal means that a single housing is bar-shaped, a flip-type terminal means that a bar-shaped housing and a flip are rotatably coupled by a hinge device, and the folder- Means that the folder is configured to be foldably connected to the bar-shaped housing by a hinge device so as to be rotatable.

Also, the portable terminal may be classified into a rotation-type or a sliding-type wireless terminal according to the opening and closing method. The rotary-type terminal means that two housings are rotatably connected to each other while facing each other while facing each other, and the sliding-type terminal means that two housings are opened and closed while facing the longitudinal direction. The variously classified portable terminals listed above can be easily understood by those having ordinary skill in the art.

The above-mentioned various types of conventional portable terminals have a disadvantage in that they are convenient only for portable purposes, and they are particularly convenient for voice or video conversation with the other party.
