An automatic ball-point pen, characterized in that it comprises, in combination: a body divided into two parts, an upper and a lower part, both parts being able to be joined together by mutual threading; a pen load provided with a spring that at one end rests on the tip of the body corresponding to the inscription ball and at the other end acts on a load stop, continually pushing it upwards; projections disposed in the interior part of the upper body of the ballpoint pen, these projections being such that they are located at different heights to allow two positions: one for projection of the inscribing ball and another for retraction of said ball; an active piece with four cross projections intended to cooperate with said projections to determine the outgoing or retracted position of the ball; and a driving part provided with clutch teeth to act on said active part, providing an intermittent rotation for its action, this actuating piece protruding in a button shape from the upper end of the ball-point pen.
