Abstract

PURPOSE: To inhibit the handling by unqualified personnel, by providing the data input means and the qualification collation processing section, and collating the qualification data inputted and the qualification range data stored on the memory media.
CONSTITUTION: The operator inputs the code of itself and the secret key to the data input means 10. The qualification collation processing section 9 checks the effectiveness of input. When effective, the control circuit 2 enters the read processing to the memory media 3 and feeds the qualification range data 7 stored on the memory media 3 to the collation processing section 9. The collation processing dection 9 collates the inputted code with the data 7 and the input means 10. If discriminated as unqualified person as a result of collation, the collation processing section 9 alarms a signal and disables the execution of either or both of the read/write to the memory media 3 with mounting and detaching set 8.
