<P>PROBLEM TO BE SOLVED: To enable a motor to be automatically controlled depending on a pressurized sate of a tank when power is cut off and thereafter power is restored while a driving operation is being performed in an air compressor using no physical power supply switch. <P>SOLUTION: When it is determined that power supply had interrupted based on a power supply voltage value detected by a power supply voltage detector 28, an air compressor control means 20 determines whether or not a motor means is driving the compressor. When it is determined that the motor means is driving the compressor, the air compressor control means 20 determines that the motor means is in an operating state or in a resting state on the basis of a pressurized state detected by a pressure detection means 12 to record information on the operating and resting states of the motor means in a nonvolatile recording means 30. <P>COPYRIGHT: (C)2009,JPO&INPIT |
