A portable hand-held fastener driving tool of the type which tends to keep the driver element better aligned with the head of the fastener while it's being driven. A biasing spring in the fastener track skews the directional path of the fastener as it is being driven, but the biasing spring does not noticeably affect the path of the driver element, thereby compensating for the slight movement of the tool (and driver) due to the tool's recoil. In an alternative embodiment, a magnet is used rather than a biasing spring, to skew the direction of the fastener as it is being shot by the tool.

1. A driver actuation device for a fastener driving tool, said driver actuation device comprising: (a) a guide body that has a fastener passageway with an exit end, said guide body being configured to receive a fastener that is to be driven from said exit end;(b) a movable driver member that, when a
1. A driver actuation device for a fastener driving tool, said driver actuation device comprising: (a) a guide body that has a fastener passageway with an exit end, said guide body being configured to receive a fastener that is to be driven from said exit end;(b) a movable driver member that, when actuated for a drive event, moves from a ready position toward a driven position and contacts said fastener, thereby causing said fastener to move in a first direction generally toward said exit end of the guide body; and(c) a biasing member that causes said fastener to change its path and move in a second direction, still generally toward said exit end of the guide body; wherein: as said driver actuation device reacts because of a recoil action due to said drive event, said driver member also changes its spatial motion so as to move generally in said second direction. 2. The driver actuation device of claim 1, wherein said biasing member comprises one of: (a) a leaf spring; (b) a hinged member that is spring-loaded; and (c) a magnet. 3. The driver actuation device of claim 1, wherein said biasing member substantially affects the movement direction of said fastener, but does not substantially affect the movement direction of said driver member. 4. The driver actuation device of claim 1, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are skewed angularly. 5. The driver actuation device of claim 1, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are offset but substantially parallel to one another. 6. The driver actuation device of claim 1, wherein said driver member again contacts said fastener after said fastener has changed its direction of movement to said second direction. 7. The driver actuation device of claim 1, wherein said driver member remains substantially in continuous contact with said fastener after said fastener has changed its direction of movement to said second direction. 8. A driver actuation device for a fastener driving tool, said driver actuation device comprising: (a) a guide body that has a fastener passageway with an exit end, said guide body being configured to receive a fastener that is to be driven from said exit end;(b) a movable driver member that, when actuated for a drive event, moves from a ready position toward a driven position and contacts said fastener, thereby causing said fastener to move in a first direction generally toward said exit end of the guide body; and(c) a biasing member that causes said fastener to change its path and move in a second direction, still generally toward said exit end of the guide body; however, said biasing member by itself does not substantially affect the movement direction of said driver member. 9. The driver actuation device of claim 8, wherein said biasing member comprises one of: (a) a leaf spring; (b) a hinged member that is spring-loaded; and (c) a magnet. 10. The driver actuation device of claim 8, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are skewed angularly. 11. The driver actuation device of claim 8, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are offset but substantially parallel to one another. 12. The driver actuation device of claim 8, wherein said driver member again contacts said fastener after said fastener has changed its direction of movement to said second direction. 13. The driver actuation device of claim 8, wherein said driver member remains substantially in continuous contact with said fastener after said fastener has changed its direction of movement to said second direction. 14. A method for adjusting the motion of a fastener in a fastener driving tool, said method comprising: (a) providing a driver actuation device, comprising: (i) a guide body having a fastener passageway with an exit end;(ii) a movable driver member; and(iii) a biasing member;(b) initiating a drive event, and moving said driver member from a ready position toward a driven position;(c) using said driver member, contacting a fastener within said fastener passageway, thereby moving said fastener in a first direction generally toward said exit end of the guide body;(d) using said biasing member, changing a path of movement of said fastener so that it moves in a second direction, still generally toward said exit end of the guide body; and(e) by itself, said biasing member does not substantially affect the movement direction of said driver member. 15. The method of claim 14, wherein said biasing member comprises one of: (a) a leaf spring; (b) a hinged member that is spring-loaded; and (c) a magnet. 16. The method of claim 14, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are skewed angularly. 17. The method of claim 14, further comprising a driver track between said ready position and said driven position of the driver member; wherein: (a) said fastener passageway comprises a fastener track; and (b) said fastener track and said driver track are offset but substantially parallel to one another. 18. The method of claim 14, further comprising the step of: said driver member changing its spatial direction of movement, due to a recoil reaction of said tool, and again contacting said fastener after said fastener has changed its direction of movement to said second direction. 19. The method of claim 14, further comprising the step of: said driver member changing its spatial direction of movement, due to a recoil reaction of said tool, and remaining substantially in continuous contact with said fastener after said fastener has changed its direction of movement to said second direction.
