ABSTRACT:
A magnetic card key-operated locking device is disclosed. The locking and opening motion of the locking device is performed by a magnetic interaction between the card key and a plurality of magnetized pins. The pins are movably placed in a plurality of holes of a perforated stationary plate, a perforated operating plate and a movable plate. The pins are repulsed by a magnetic plate to cause the operating plate to be coupled to the stationary plate and thereby lock the locking device when there is no card key in a key insert slot. However, when there is a card key in the key insert slot, the pins are repulsed by the card key toward the magnetic plate to cause the operating plate to be separated from the stationary plate but to be coupled to said movable plate and thereby open the locking device.
