IMPROVED NAIL PLACEMENT DEVICE

A fastener driving device including a positioning mechanism for positioning a nail into an opening in a workpiece. The positioning mechanism includes an opening locating structure (60) movably connected to the movable assembly (45) of the contact trip assembly (42) and adapted to extend into the opening so as to align the nosepiece (18) with respect to the opening. The opening locating structure (60) is movable relative the movable assembly (45) of the contact trip assembly (42) between an extended position and a retracted position and biased toward the extended position by a first biasing spring (68) to facilitate locating of the opening, and movable to the retracted position when the opening locating structure is pressed against a workpiece. The positioning mechanism further includes a guiding structure (90) movably connected to the nosepiece structure (18), the guiding structure being biased by a spring (100) to extend forwardly to guide the fastener in a driving track (28) inside the nosepiece (18).
