PURPOSE:To avoid the mixture of both error logs by preparing two types of files for error information to store the error information detected during a real operation into one of both files with the pseudo error information detected in a device test state stored in the other files respectively. CONSTITUTION:A state deciding means 3 decides whether a device is set under a real operation state or a test state by an instruction given from a main control part of the device main body. Then the means 3 controls a data allocating means 4 so that log data is stored in a real log storing means 1 in a real operation state and then stored in a test log storing means 2 in a test state respectively. Thus it is possible to avoid automatically such a case where the pseudo log data produced for test is mixed into a log data string detected and recorded in the real operation state without giving any load on an operator. |
