A pusher piston shifts a nail by a predetermined distance along an eject hole before a driver blade drives the nail. In this case, the predetermined shifting distance of the pusher piston satisfies a requirement that the tip of the nail protrudes out of the eject hole while the nail itself is not removed off a band member. Thus, the nail is surely held by the band member even when the nail is positioned at the pushed-out position where the tip of the nail protrudes out of the eject hole.

[ What is claimed is:] [1.] A pneumatically operated nail driver comprising:a nail guide for loading a nail assembly of a plurality of nails serially connected by a band member, each nail being separable one after another from said nail assembly;a nail feeding mechanism for successively feeding the nails from said nail guide one after another into an eject hole;a driver blade for pushing a nail positioned in said eject hole and driving said nail out of the eject hole; anda pusher piston for shifting said nail by a predetermined distance along said eject hole so as to cause the tip of said nail to protrude out of said eject hole without removing said nail from said band member, so that said nail is held in place by said band member before being driven by said driver blade.
