Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an injection molding machine capable of extending an output holding time of voltage when electric power cut-off occurs by adding a simple circuit configuration. SOLUTION: In the molding machine having a plurality of motors, and each of which is controlled through drives 15 to 18 with a molding machine control device 20 for controlling molding operation, an energy holding circuit is provided on a convertor circuit 11 supplying a plurality of drivers with a controlling direct-current voltage and a convertor circuit 21 supplying the molding machine control device with the controlling direct-current voltage.
