PURPOSE:To prevent a person other than a proper maintenance man from changing the internal state of an information processor by providing a discriminating means to discriminate whether an operator is the proper maintenance man or not. CONSTITUTION:The maintenance man can issue indications to a diagnostic processing processor part 2 through an input/output device 3 having a display part and keyboard and can read results. An ID card discriminating device 4 is connected to the diagnostic processing processor part 2, and the discrimination result of the ID card discriminating device 4 is read out through a signal line 11. Consequently, maintenance operation commands are not accepted unless the operator is discriminated as the proper maintenance man. Thus, only the proper operator can perform maintenance and diagnosis to prevent the wrong use. |
