Abstract

A device for unlocking a lock recognizing a punched card includes a card recognition unit and an unlocking unit. The card recognition unit comprises: a base plate into which a card provided with a plurality of holes is inserted; a moving plate which is coupled to the base plate in such a manner that the moving plate can move closer to or away from the base plate; a first recognition unit that recognizes the holes in the card depending on insertions into the holes in the card in the process of the moving plate moving closer to the base plate; and a second recognition unit that recognizes the absence of a hole in the card based on contact with the area of the card lacking holes in the process of the moving plate moving closer to the base plate. The unlocking unit unlocks the lock based on the recognition results of the first and second recognition units.

Description

technical field [0001] The present invention relates to a locking / unlocking device, and more particularly, to a locking / unlocking device for unlocking a door by punched card identification. Background technique [0002] Generally, a door lock is a device for locking a door or unlocking a locked door. In recent years, with the improvement of security reliability and convenience of use, various types of digital door locks—including key insertion type, fingerprint recognition type, RF (radio frequency) type, card recognition type, etc.— — usage is gradually increasing. Conventional digital door locks of the key insertion type, RF type, or card recognition type cannot operate if a malfunction or defect occurs in the circuit or the power supply discharges. Korean Registered Patent No. 0528505 titled "Door Lock Device" discloses a card recognition type door lock. According to this prior art, the door lock device is unlocked when the plurality of perforations on the card match w...
