PURPOSE:To efficiently diagnose each part individually by judging the probability of faults of each part in a device including plural parts. CONSTITUTION:When an operator inputs the name and using time of a replacement part that the wants to have diagnosed from an input part 3, a trouble pattern read part 63 reads a table of trouble patterns of replacement parts inputted to each input part 61 out of a memory part 8. Next a comparison part 64 compares the using time and range of the table read by the read part 63, both of which are inputted to a using time input part 62. Then the mark of the trouble pattern including the using time in the hour range of the trouble pattern is obtained. Then a trouble pattern decision part 65 reads the trouble pattern from the mark of the trouble pattern with the aid of the table of trouble patterns, and decides the trouble pattern. An output part 4 displays the trouble pattern of the replacement part, whereby the operator can know the the trouble pattern of the replacement part and the probability of trouble. |
