Zusammenfassung:	PROBLEM TO BE SOLVED: To make the amount of a resin stored by metering by stabilizing the metering. SOLUTION: A heating cylinder 11, a screw 12 arranged to be rotatable and forward/backward movable in the cylinder 11, a molding material supply means 104 for supplying a molding material to the cylinder 11, a retreat speed detecting means 105 for detecting the retreat speed of the screw 12, and a molding material supply changing means 106 for changing the amount of the molding material to be supplied based on the retreat speed of the screw 12 are provided. Since the retreat speed of the screw 12 can be kept constant, the metering can be stabilized, and the amount of the molding material to be stored by the metering can be made uniform.
