<p>PROBLEM TO BE SOLVED: To obtain an information storage system which can prevent a password stored in the internal memory from being tapped by cutting off the power supply to the wire extended between the memory and memory power source over an internal surface, thereby erasing the password stored in the memory. SOLUTION: A system control board 30 is provided with a logic circuit 32 which operates according to the opening/closing state of the door of a data storage system and the use state of the key of the door. The logic circuit 32 once detecting an abnormal state, wherein the door of the system is open while being locked, sends a power-OFF command to the power source part 50 to cut off the power supply to a storage device 10. Consequently, it is impossible to access the storage device 10. A security board 30 is put in a security case where a wiring film is spread over, so even if an action of tapping the password is tried, the password is erased to prevent the password from being tapped.</p> |
