PURPOSE: An automatic repairing method in error generating is provided to output an error message only in case that the control unit detects an error and tries to restore the failure, but the return to normal condition cannot be made. CONSTITUTION: A microcomputer detects the generation of an error using an error generation signal generated from the error detection sensor installed in each block. When an error generation is detected, the repairing operation for each error is carried out. It is confirmed whether the error failure is eliminated, after the execution of the repairing operation. An operation before the generation is carried out if the error failure is eliminated and the repairing operation for each error is carried out repeatedly if the error failure is not eliminated. If the number of the repairing operation is more than 3 times for an identical error, an abnormal state generation indication is carried.
