<p>PROBLEM TO BE SOLVED: To provide the data processor having the high-grade data security protection function. SOLUTION: When the connection part of a data storage device 22 is connected to a connection connector 3 of a data processor main body 21, power is suppllied to a microprocessor 51, ana the microprocessor so outputs a discrimination signal to the data processor main body 21. If the inputted discrimination signal is a prescribed signal, the data processor main body 21 outputs the decision signal to the data storage device 22. If this decision signal is not inputted or is not a prescribed signal, the microprocessor 51 makes a control part 6 inactive to inhibit the data read from a memory part 5 and turns off a switch 53 and turns on/off a switch 54 like a pulse to erase data stored in the memory part 5.</p> |
