Description

  The present invention relates to a portable communication terminal, and more particularly to a portable communication terminal such as a foldable mobile phone.

  2. Description of the Related Art In recent years, a foldable mobile phone as a representative mobile communication terminal has a tendency to increase the weight of the terminal body due to an increase in the size of a display screen and a camera. Certainly, the large display screen is useful for reading long emails and browsing the browser. However, when making a call or reading a short e-mail, such things only add weight and put a burden on human hands. In addition, when the phone is foldable, it is not necessary to open or close the upper and lower housings that make up the foldable mobile phone, such as when making or receiving calls. However, such an operation is necessary, and it may be rather inconvenient. Furthermore, since the thickness of the mobile phone increases, it is not very convenient in terms of being easily carried in a pocket.

  Therefore, a foldable portable communication terminal in which a main body case and a cover case are separable has been known (for example, see Patent Document 1). This conventional portable communication terminal includes a main body case having a key disposed on the front surface and / or the back surface, a cover case having a display unit that can be folded with respect to the main body case, and the cover case attached to the main body case. Folding means, etc., that can be foldable are provided, and the folding means has a separating means that allows the cover case and the main body case to be separated.
