、装置の安全性を極めて高めることができる。As described above, when the present invention is used as a stop control device for a diesel engine, it goes without saying that the stop operation can be performed as easily as an electric ignition gasoline engine. Since power is supplied to the solenoid drive circuit through the first switching element of the power supply control circuit that responds to the output of the circuit, and power is supplied to the power supply control circuit through the first switching element. After the timer circuit is activated, each power supply circuit can be opened by the first switching element, so that not only is there no power loss to each component of the power supply control circuit and solenoid drive circuit, but also no voltage is applied. The safety of the device can be greatly improved.
