It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Fig. 1 is a perspective view of a terminal according to an embodiment of the present application. Fig. 2 illustrates an exploded view of the terminal 100 according to an embodiment of the present application. Fig. 1 and 2 show a smartphone as an embodiment of the terminal 100, but terminals including a display screen such as a tablet PC, a notebook PC, and a PDA may also be used as an embodiment.
