As the functions of mobile communication terminals including mobile phones are diversifying day by day, the storage capacity is gradually increasing.

For example, mobile phones with digital cameras capable of taking pictures and videos, or mobile phones with MP3 players, have evolved toward higher functionality and capacity, requiring separate storage media.

As a result of the need for additional memory, mobile communication terminal companies have built additional large-capacity memory inside the mobile terminal due to additional functions other than mobile phones (such as digital camera functions and MP3 player functions). The large memory that is selectively used according to the increase in price and preference has a disadvantage of unnecessary waste for users who do not use it.

In order to solve this problem, Korean Patent No. 10-0513836 has an inclined surface formed at one side edge of the tip, and a memory card having a locking groove formed at the rear side of the inclined surface is inserted into the card slot of the housing and installed at the rear end of the housing.
