Zusammenfassung:	PROBLEM TO BE SOLVED: To miniaturize an injection machine by shortening a screw and a heating cylinder. SOLUTION: The heating cylinder 11, a molding material supply means for supplying a molding material to the heating cylinder 11, and the screw 12 which is arranged in the heating cylinder 11 to be freely rotatable and freely forward/ backward movable and in which a compression zone Q2 and a metering zone Q3 are formed are provided. The molding material supply means has a conveyer for conveying the molding material, a preheating means for preheating the molding material, and a driving means for driving the conveyer. Since a supply part can be eliminated by the compression zone Q2 and the metering zone Q3 in the screw 12, the screw 12 and the heating cylinder 11 can be shortened, so that the injection machine can be miniaturized.
