The invention relates to a multi-directional slide input device for a portable terminal, which comprises: a base, which is mounted on the terminal and includes a rectangular-shaped operation surface and a wall formed along the frame of the operation surface, the wall having at least four stationary contact points therein; an X-axis moving stage, which is provided with an X-axis sliding portion formed in a protruding manner on the upper and lower sides of the wall to move in the horizontal direction while being seated on the operation surface, and with a Y-axis moving guide formed in a protruding manner inside the wall on both lateral sides thereof; a Y-axis moving stages, which has an installation surface to install at least one key input means thereon, the installation surface having a wall formed along the frame thereof, and is provided with a Y-axis sliding portion to be coupled with the Y-axis moving guide so as to move vertically within an opening and with an actuation operating portion arranged, on the outside of the wall, at a distance, the actuation operating portion having a multiplicity of actuation contact points coupled to the key input means; and a circuit board, which is mounted on the installation surface of the Y-axis moving stages and has a keypad contact point. It is an advantage of the invention that various electric actions are executed by the operation of the stationary and moving contact points through the sliding motion from the central point of the Y-axis moving stages towards a target direction and the return motion towards the central point, and by the operation of the key input means.
