A keypad lifting mechanism includes a first board, a guiding piece, a second board and a third board. The guiding piece defines a guiding hole. The guiding hole includes a transverse end portion. The second board includes at least one protrusion. A guiding post is formed on the second board for engaging in the guiding hole of the guiding piece. The third board includes at least one slope corresponding to the at least one protrusion. When the guiding piece is pushed away from the third board, the guiding post slides along the guiding hole of the guiding piece. The second board moves with the guiding piece when the guiding post reaching the transverse end portion of the guiding hole. The third board is raised by the at least one slope sliding up along the at least one protrusion of the second board.
