Claims

[Scope of utility model registration request]

A key card with an appropriate number of magnets is pressed against the sensor, the sensor detects the arrangement of the magnets on the key card, and the control circuit compares the arrangement set internally with the arrangement of the magnets to find a match. An unlocking device using a magnet that unlocks the lock only when the lock is unlocked, has holes I and C arranged in correspondence with all the unlock codes of the key card that can be obtained by arranging the magnets, and each hole I and C has a A sensor device for an unlocking device using a magnet, characterized in that it is equipped with a bias magnet.
