PROBLEM TO BE SOLVED: To reduce the number of power feeding lines to a second switching element driving circuit side from a first switching element driving circuit side. ;SOLUTION: A DC output of a DC power supply circuit 24 is given to a primary winding 28s of a first transformer 23 of a DC/DC switching regulator circuit 27. First switching driving circuits 31a to 31d are connected to the secondary windings 28a to 28d of a first transformer 28. A primary winding 33s of the second transformer 33 is connected to the secondary winding 28d in the secondary windings 28a to 28d of the first transformer 28 and the second switching driving circuits 34a to 34d are connected to the secondary windings 33a to 33d of the second transformer 33.;COPYRIGHT: (C)1997,JPO
