A fastener driving tool as in claim 1, wherein the trigger is prevented from moving from the OFF position to the ON position when the tool is in the drive inhibit mode. 14. A fastener driving tool as in claim 1, wherein the trigger is prevented from moving from the OFF position to the ON position in the drive inhibit mode. 15. A nail gun comprising: a nail drive mechanism; a trigger movable from an OFF position to an ON position for actuating the nail drive mechanism; a mode change device operable to selectively change a tool mode among a first drive mode, a second drive mode and a drive inhibit mode for the nail drive mechanism; a contact arm serving to cooperate with the trigger for controlling the actuation of the nail drive mechanism, the contact arm being movable between a first position and a second position; the first drive mode enabling the actuation of the nail drive mechanism when the trigger and the control member are moved in either a first sequence, in which the trigger is moved from the OFF position to the ON position after the contact arm has moved from the second position to the first position, and a second sequence, in which the contact arm is moved from the first position to the second position after the trigger has moved from the OFF position to the ON position; the second drive mode enabling the actuation of the nail drive mechanism only when the trigger and the control member are moved in the first sequence; and the mode change device including an operation member that is operable by an operator, the operation member having a plurality of operational positions that correspond to the changeable modes. 16. A fastener driving tool comprising: a fastener drive mechanism; a trigger pivotable about a first axis from an OFF position to an ON position for actuating the fastener drive mechanism; and a mode change device operable to selectively change a tool mode between a first mode that prevents actuation of the fastener drive mechanism, and a second mode that enables actuation of the fastener drive mechanism; the mode change device being operable to shift the position of the first axis of the trigger in response to a change between the first mode and the second mode. 17. A fastener driving tool as in claim 16, wherein the mode change device includes a support shaft that is rotatably supported by a tool body about a second axis, the support shaft including a shaft portion, the first axis being defined along the shaft portion, and the first axis and the second axis are displaced from each other. 18. A fastener driving tool as in claim 16, wherein the trigger is prevented from moving from the OFF position to the ON position in the first mode. 19. A fastener driving tool as in claim 18 further including a stopper that is positioned to oppose to the trigger in the first mode, so that the stopper can prevent the trigger from moving from the OFF position to the ON position. 20. An apparatus comprising: a tool body, means for driving a fastener, the fastener driving means being disposed within the tool body, a trigger coupled to the tool body and movable from an OFF position to an ON position, and means for selecting a tool mode from among an unlimited drive mode, a limited drive mode and a drive inhibit mode, the tool mode selecting means comprising an operation member that is operable by an operator, wherein the operation member has at least three operational positions that respectively correspond to the unlimited drive mode, the limited drive mode and the drive inhibit mode. 21. An apparatus as in claim 20, further comprises a contact arm having a first end and a second end, wherein the first end is arranged and constructed to contact a workpiece into which the fastener will be driven and being movable from a first position to a second position when pressed against the workpiece and wherein the second end is operably coupled to the trigger and the tool mode selecting means. 22. An apparatus as in claim 21, wherein in the limited drive mode the fastener driving means is actuatable only when the contact arm has first moved from the first position to the second position and then the trigger is moved from the OFF position to the ON position. 23. An apparatus as in claim 22, wherein the tool mode selecting means is operable to shift the second end of the contact arm in a direction substantially perpendicular relative to the moving direction of second end when the contact arm moves between the first position and the second position. 24.
