In addition, the display unit 113 may further include a touch pad to enable input of information by a user's touch. In addition, the display 113 may be formed to generate various tactile effects that a user can feel when touched. This may be implemented by a haptic module linked to the display 113. Vibration is a representative example of the haptic effect generated by the haptic module. The haptic module may be variously disposed according to the configuration aspect of the mobile terminal as well as the display 113.

The sound output unit 114 may be implemented in the form of a receiver or a speaker.

The first image input unit 115 may be implemented in the form of a camera module for capturing an image or a video of a user.

The first operation unit 116 receives a command for controlling the operation of the mobile terminal according to an embodiment of the present invention. The first manipulation unit 116 may be formed as a touch screen together with the display 113.

Like the first body 110, the front case 121 and the rear case 122 may form a case of the second body 120.
