Abstract:
1. A lancing apparatus for moving a lancing element in a lancing direction from a wait position to a lancing position to lance an intended portion with the lancing element, the lancing apparatus comprising: a first member which is reciprocally movable in the lancing direction and in a retreating direction which is opposite from the lancing direction; a second member which moves along with the lancing element and performs reciprocal movement in the lancing direction and the retreating direction in accordance with the movement of the first member; and movement conversion means for converting the reciprocal movement of the first member into the reciprocal movement of the second member in a manner such that a directional change of movement of the second member from the lancing direction to the retreating direction is performed during a one-way stroke of the first member in one of the lancing direction and the retreating direction; wherein the first member is reciprocally movable between a first fixed position and a second fixed position; wherein the second member performs one cycle of reciprocal movement between a third fixed position and a fourth fixed position during one cycle of reciprocal movement of the first member between the first fixed position and the second fixed position.
