Abstract
A locking doorknob which recognizes a fingerprint, in which the detecting sensor of a fingerprint is installed on the spot of the doorknob that a thumb or other fingers are placed naturally as the door is being opened. The location of the detecting sensor of the fingerprint can be changed at the discretion of a user to correspond to such a location. During operation, as soon as a user holds the doorknob, his fingerprint is measured and searched, and if the fingerprint corresponds to a fingerprint previously input, the door is unlocked and the doorknob can be turned to open the door. In this way, fingerprint recognition and opening of the door are performed at the same time.
