Abstract

PURPOSE: To manage password data safely by providing a function which monitors a cable state when the password code data is inputted, and erasing the data if abnormality is found. CONSTITUTION: This device is equipped with an input device 3 for inputting a password, an output device 2 which outputs the input result, a data storage memory 4 which stores the inputted password data, and a data transmission and reception module 5 which transfers the password to external equipment. Then a cable state monitor module 6 which detects the state of a cable for connection with the external equipment or internal voltage abnormality is added and when the cable state monitor module 6 detects abnormality, the stored password data are erased. Consequently, once the voltage abnormality or cable abnormality is detected, since the password data inputted to the password input device 1 are erased, the password data can be protected even if illegal operation is tried.
