Claim:
1. A device for throwing targets comprising a rotationally movable throwing arm, draw-spring and geared motor powered by a power supply and comprising an output shaft comprising a first axis of rotation for cocking the arm by rotation of said arm up to a so-called “zero point” position where the draw-spring is in tension without exerting a torque on the arm, wherein it comprises a stop carried by the geared motor and a complementary stop carried by the arm, with the stop and the complementary stop being so configured as to be in abutment in a throwing position what is beyond the “zero point” so as to lock the arm in said position on a predetermined angular sector in a direction of rotation of the arm wherein the draw-spring is in tension and exerts a torque on the arm and as to release the arm beyond the throwing position wherein the draw-spring relaxes to rotate the arm for throwing the target and wherein the arm comprises a rotating shaft, with said shaft carrying a pinion comprising a second axis of rotation driven by a second drive pinion comprising a third axis of rotation connected to the output shaft, with the stop being carried on the periphery of a crank pin comprising a fourth axis of rotation rotating about the output shaft of the geared motor wherein the crank pin is engaged with the output shaft, the first axis of rotation of the output shaft, and the device comprising a contactor which is configured to cut the power supply when contacted by an end of the arm thereby stopping the geared motor, the contactor being positioned substantially in contact with the end of the arm at the “zero point” position, and wherein the first, second, third, and fourth axes of rotation are coaxial.
