<p><P>PROBLEM TO BE SOLVED: To reduce power consumption while safely shutting down a controller even if a power switch is turned off in the middle of starting processing. <P>SOLUTION: A composite machine 100 includes a power supply circuit which supplies power to an engine 13 via a rectifying smoothing circuit 4 and a converter 6, and a power supply circuit which supplies power to the controller 14 via a relay circuit 3, a rectifying smoothing circuit 5, a converter 7 and the like. When an AC switch 2 is turned off, the power supplied from a power source 1 to the engine 13 is blocked. On the other hand, power supply to the controller 14 is not blocked even if the AC switch 2 is turned off. After a controller control part 16 finishes predetermined shut-down processing for safely stopping the controller 14, an off-signal is sent to the relay circuit 3 to turn off the relay circuit 3, whereby power supply to the controller 14 is blocked. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
