Effects of the Invention This invention is equipped with a demagnetizing means consisting of a magnetic field generating device for generating magnetic flux for demagnetizing within the exit of the room; and a magnetic field control circuit for controlling the magnetic field generating device. In other words, even if you pass through the exit after completing the procedure of stopping the operation of the magnetic field generator by the magnetic field control circuit, the floppy disk, magnetic tape, etc. will not be demagnetized. If you do not do this, the magnetic generator will operate and generate magnetic flux inside the outlet, demagnetizing the floppy disk, magnetic tape, etc. inside the storage case.

Therefore, there is no risk of important information being leaked to the outside due to unauthorized removal of floppy disks, magnetic tapes, etc.

For example, copying a floppy disk, etc.
Even if the original floppy disk is returned to the file shelf, there is no way to stop the magnetic generator when taking the copied floppy disk outside.

Therefore, the data is safe because it is taken out of the room in a destroyed state.

In addition, since it is equipped with a file management system consisting of a file sensor installed on the file shelf and monitoring each storage case; and an alarm device connected to the file sensor via a file control circuit, regular procedures and In other words, even if the storage case is removed from the file shelf after the file control circuit has taken the procedure to stop the file sensor and alarm device, an alarm will not be generated, but if the formal procedure described above is not followed, the file The sensor and alarm device are activated and an alarm is issued.

Therefore, unauthorized removal of the storage case can be immediately detected.

In addition, the printer can automatically print out the owner, date and time of the punch card that took the file out of the computer room, so even if the file is taken out through the proper procedure, it can be traced from the printed paper when and by whom it was taken out. You can also do that.

In this way, according to this computer security system, floppy disks, magnetic tapes, etc. can be managed safely and reliably.
