<p>PURPOSE:To prevent error action from being generated due to a card key, on a locking device having composition for changing the projecting quantity of tumblers according to the bored patterns of penetration holes arranged on the card key, and setting a moving slider to be an engaging member. CONSTITUTION:When a card key P is advanced into a card channel 21 in an unlocked state, then a stopper 24g, tumblers 23b-23f on an advance side are pushed into and the card key P is brought in contact with a stopper 24a to be projected in a regulation channel 22. At the same time, penetration holes P1-P2 coincides with the sharp head sections 26b-26f of the tumblers, and engaging projected sections 28b-28f are posioned at a sliding channel 19a, and a slider 16 is moved together with the card key P. After that, when the slider 16 is stopped, then the stopper 24a overpasses a gradient 22a and is pushed on the side of the slider 16, and so the key card P is allowed to pass, and the stopper 24g on the advance side is projected in the regulation channel 22, and the advance of the card key from the same direction is suppressed.</p> |
