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.
