Abstract
An injection screw disposed in a heating cylinder is connected to a rotary driving force receiving mechanism, a linear driving force receiving mechanism, and a back pressurizing mechanism. The rotary driving force of an electric motor is transmitted to the rotary driving force receiving mechanism and the linear driving force receiving mechanism through clutches, which are controlled according to sensors for detecting the position of the screw or the linear driving force receiving mechanism.
