PURPOSE:To enable delicate adjustment as the titled machine is high in energy efficiency and superior in control accuracy and necessary respective actions can be selected freely, by driving the machine by making driving force of two units of servomotors combine and intermit by making use of a plurality of clutch mechanisms. CONSTITUTION:A clutch 7 is operated and a screw 3 is made to rotate by power of a servomotor 5 for plasticizing. When established torque is adjusted, back pressure of a screw is diceded arbitrarily as a servomotor 12 generates torque in the directions of a positive and reverse turns. A measured stroke of the screw 3 can be set by a detector 12A fitted to a rotary shaft of the servomotor 12. When a clutch 17 is engaged a moving plate 24 is advanced by driving force of the servomotor 12 and closing is performed. Then after nozzle touch of an injection unit 1 has been made to perform to a mold 22 by a clutch 29, a clutch 15 is made to act, the screw 3 is made to advance at a predetermined speed program by a rotary angle detector 12A and measured molten resin is made to inject into the mold.
