A portable terminal which selectively opens and closes an electric component is provided to open and close the electric component by using vibration of the portable terminal and minimize the entire thickness of the terminal according to a switch. A vibration driving unit(60) comprises a vibrating body(61) and a moving body(62). The moving body vibrates according to power source. A moving protrusion(63) protruded from the moving body is inserted into a displacement slot(64) formed in a protective cover. A protecting member(50) is positioned on a front based on an image capturing direction of a second image input unit(28) in order to open and close an opening part of a rear cover(22). A moving body moves to a direction which is set up in the vibration of the vibrator. A serration is formed in the upper side of the vibrator into the particular direction. The moving body moves in a particular direction by interaction with the serration.
