PURPOSE:To enable to reduce energy consumption of a driving system, by accumulating and releasing the inertial energy temporarily by use of elastic members in controlling a reciprocating body. CONSTITUTION:Springs 31A, 31B are disposed such that a body 6 comes into contact with either of these two springs 31A, 31B when the body 6 comes to one of speed-changing sections located on the sides of a driving system and the body 6 is moved while causing deformation of the spring. With such an arrangement, the inertial energy of the body 6 is converted into strain energy of the springs 31A, 31B and accumulated in the springs. When movement of the body 6 is stopped at last, it is moved in the opposite direction by the energy accumulated in the spring. Therefore, it is enabled to reduce energy consumption of the driving system. |
