PURPOSE:To smoothly control the whole system by properly stopping or starting a slave CPU before and after automatic power-ON/OFF operation by a main CPU. CONSTITUTION:The OFF set time stored in the nonvolatile RAM 12 of a main CPU block 10 is compared with the time of a timer IC 13 and when both the times match each other, an OFF condition communication from the main CPU 11 to the slave CPU 21 is made through a communication means 7. In response to the condition communication, the slave CPU 21 performs processing as to whether or not the slave CPU 21 can be turned OFF and when so, an indication for OFF processing is sent from the main CPU 11 to the slave CPU 21; and then a relay breaking command for stopping the supply of electricity to a 2nd system power circuit is outputted from the main CPU 11 to a relay breaking means. |
