Title:
CARD OPERATION TYPE LOCK APPARATUS
Document Type and Number:
Japanese Patent JPS62228574
Kind Code:
A
Abstract:
A coded card key (14) is insertable through a slot (15) to bring into alignment coded magnetic areas on the card with magnetic pins (28) of the lock to unlock a core (24) relative to a locking plate (21) and enable the core (24) to be driven downwardly by the card engaging its lower flange (26) and to actuate an apparatus, typically a door-lock. The core (24) has a cam having a first cam part (54) which is engageable by the card (14) and a second cam part (55) which abuts a limit spring (56) when the core (24) has reached the unlock position, whereby the core (24) keeps the unlock position as long as the card (14) engages the cam part (54). Withdrawal of the card (14) by the user allows return movement of core (24). The user can release the card for actuating e.g. a door-knob, instead of having to hold the card down in the lock while rotating the door-knob.
