PUNCH CARD KEY AND PUNCH CARD KEY RECOGNITION APPARATUS FOR RELEASING LOCKING STATUS

摘要

PURPOSE: A through-hole card key and a locking releasing apparatus capable of recognizing thereof are provided to prevent an illegal copy and improve security by releasing locked status when successfully recognizing the through-hole pattern of the through-hole card key and a first and a second non-through-hole pattern. CONSTITUTION: A locking releasing apparatus(100) is comprised of a handle unit(110) which is installed at the outside of a door; a releasing operation platform(120) which releases the locking status of a lock bundle which is installed at the inside of the door; a key insertion unit(130) which inserts the through-hole card key; a key recognition unit(140) which performs a recognition of a through-hole pattern and a first and a second non-through-hole pattern of the through-hole card key according to a rotation of the handle unit in a status in which the through-hole card key is inserted into the key insertion unit, and transmits the rotation force of the handle unit to the releasing operation platform when the recognition succeeds; and a key returning unit which puts the through-hole card key in a returnable status from the key insertion unit according to the rotation of the handle unit after the locking status of the key bundle is released. The key recognition unit is comprised of a plurality of recognition bars which arrange each of the lower part correspondingly to the through-hole pattern and the first and the second non-through-hole pattern of the through-hole card key, and forms a protrusion pin in each side; a recognition bar moving unit which independently raises the recognition bar; a pattern plate which forms a first, second, and a third pattern hole which are located to fit the through-hole pattern, and the first and the second non-through-hole pattern to the height of the protrusion pins when the recognition bars descend, which guides the protrusion pins to enable the slide movement to the handle unit direction only when the recognition succeeds, and receives the elastic force to the handle unit; and a rotation power interruption unit which delivers the rotation power of the handle unit to the releasing operation platform in a slide movement status of the pattern plate to the handle unit direction.
