PROBLEM TO BE SOLVED: To completely perform drive control of a fan motor without need for addition of components, and to suppress apparatus cost from increasing.SOLUTION: Control means 10 outputs, to first switching means 20, a driving signal corresponding to a rotation request at a first speed under a control state on the basis of a rotation request at a second speed from an OFF request because a rotation request is not obtained at the first speed and, after a predetermined time has passed, outputs a driving signal on the basis of the rotation request at the second speed to second switching means 30. |
