摘要 <P>PROBLEM TO BE SOLVED: To optimally attain integration of non-volatile memories which are distributed into a plurality of control substrates. <P>SOLUTION: Programs and various kinds of setting data to be used in the CPU 11 of an operation part 10, the CPU 21 of a CTL 20 and the CPU 31 of an engine control part 30 are integrated into and stored in the Flash_ROM 26 of the CTL 20. Thus, it is facilitated to perform replacement after mass production, and cost is reduced. A storage medium which appears on a market a lot is used by constituting the Flash_ROM 26 of a NAND type flash memory which is superior also in terms of cost. In addition, the operation part 10, the CTL 20, and the engine control part 30 are provided with small-capacity NVRAMs 13, 23, 33 for storing minimum required programs in starting respective parts. Thus, minimum required starting is performed and this enables notification of an abnormality being produced, even when any one of the parts does not start up. <P>COPYRIGHT: (C)2010,JPO&INPIT
