For example, in the meas for driving balls using a spring . as a power source a DC motor 1 is employed to rotate a grooved cam 3 through a train of reduction gears 2, the gradient of the groove in the cam 3 causing the spring to be compressed. The coil spring 7 is compressed through a roller contact 4, which follows the grooved cam 3, a guide shaft 5 and a rod 6 to acumulate prescribed energy. The energy is released when the contact 4 has arrived at a position where the contact 4 will be free to leave the grooved cam 3. Through the released energy a ball driving plate 8 hits a ball 17 to drive it through a cylinder 9.
