Zusammenfassung:	PURPOSE:To prevent an occurrence of a fire or other troubles caused by the defective connection of connectors by performing a control operation only when a specified signal is input from a specified pin of a connector on the side of the section to be controlled through a specified pin of a connector on the printed board side. CONSTITUTION:An electric circuit 8 and a cooling fan 6 placed on the side of the section to be controlled are electrically connected by a connector on the printed board side 19 and a connector on the side of the section to be controlled 20. When the two connectors are correctly connected, a No.1 pin of the connector 19 is connected correctly to that of the connector 20 and a No.4 pin of the connector 19 to that of the connector 20. Therefore, a microcomputer 9 judges that a high-level specified signal is input into an input port IN1, determining that the connectors 19 and 20 are connected correctly. In the case that the connectors 19 and 20 are not connected correctly, the microcomputer prohibits the cooling fan 6 and an microwave oscillation circuit 16 from driving.
