PROBLEM TO BE SOLVED: To provide a technique for avoiding an influence of a noise generated from a switching power source circuit easily with high accuracy.SOLUTION: A power source circuit includes: a switching power source that converts a voltage from an external power source into a voltage for operating a load and outputs the voltage to the load; a control unit that monitors a switching operation of the switching power source and an operation of the load; and a voltage adjustment circuit that adjusts the voltage output from the switching power source on the basis of a monitoring result by the control unit, and feeds back the adjusted voltage to an oscillation circuit that controls the switching operation of the switching power source. |
