After that, the door cannot be opened unless the parties enter the proper number using the numeric keypad 13.

Since the size of the card 11 is specified, after insertion, the lower part is held by the leaf springs 8 and 8 at the rear of the insertion port 3 and stands upright in the gap 4. In this state, the card 11 is placed outside the door. Although it cannot be pulled out after returning to the door, the parties can easily pull it out from the gap 4 by turning to the rear side of the door after opening the door.
