<P>PROBLEM TO BE SOLVED: To satisfactorily restrain changes in power source voltage even when any one of a plurality of electronic devices is driven, in an electronic apparatus that has the plurality of electronic devices supplied with power from single power source. <P>SOLUTION: Regularly, both a FAN 1 and a FAN 2 are driven at their full speeds. When a solenoid 430 is turned on at time t<SB>1</SB>, the FAN 1 is driven at 35% of the full speed at the same time. At time t<SB>2</SB>subsequent to time t<SB>1</SB>, the FAN 2 is driven at 45% of the full speed. At time t<SB>3</SB>, the FAN 2 is stopped. At time t<SB>4</SB>subsequent to time t<SB>3</SB>, the FAN 1 is stopped. In addition, when the solenoid 430 is turned off at time t<SB>5</SB>, the FANS 1 and 2 are turned on at the same time. Consequently, changes in the current of the solenoid and changes in the currents of FANS 1 and 2 are offset. This restrains changes in 24V current and 24V voltage, and hence restrains changes in the number of revolutions of a motor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
