  • Patent number: 6769591
    Abstract: In a nailing machine in which a linear-sheath-shaped magazine for storing therein connected nails connected together in a linear manner is disposed so as to be continuous with a nose part, the connected nails are supplied from the magazine to an injection port formed in the nose part, and the connected nails are then driven out of the injection port by a driver, a magnet is disposed on a supply guide surface which is used to guide the nails from the magazine to the injection port of the nose part, and such portion of the shaft of the nail as ranges from the longitudinal-direction center of the nail shaft portion to the leading end side portion thereof is attracted and held by the magnet to thereby be able to prevent the leading end side portion of the shaft portion of the nail left in the injection port from entering into the magazine.
