A mechanism for the actuation of cinematographs that essentially consists of a ratchet wheel mounted on an axis that in turn carries a gear wheel that engages the cinematographic tape and makes it advance. The ratchet wheel is driven by a lever with two articulated arms at its point of unión and in turn by an eccentric that when giving rise to an up and down movement of one of the arms of the lever causes the other to advance to each movement a tooth of the ratchet wheel thanks to the tension of a spiral spring that makes act at the same time a counter pawl that avoids any recoil movement and immobilizes the axle of the ratchet wheel obtaining thus the discontinuous rotation that drags the tape cinematographic with which the wheel that drags the cinematographic film is spinning in a discontinuous manner.
