An improved ballpoint pen, essentially characterized by having the container containing the ink, finished in the writing ball, longitudinally displaceable inside the sheath or external body of the instrument, subjected to the action of a spring that tends to keep it hidden and supported, on the opposite side to that carried by said ball, in a piece that, prevented from rotating, is supported, in turn, in another rotating part provided with one or more inclined parts that, when the rotation thereof occurs in contact with the one that can not rotate, they provoke the rectilinear displacement of this one and of the deposit of the ink so that, overcoming the action of the spring to which the last one is subjected it is going to appear the same enough by the end of the referred external body the terminal ball is in the proper position to perform the writing.
