1. A fastener magazine for a fastener driving tool, comprising:
(a) a magazine housing including a first end and a second end, and a longitudinal axis that extends between said first and second ends, said magazine housing configured to hold a plurality of fasteners that are placed between said first and second ends and are movable therebetween;
(b) a mounting bracket on said magazine housing proximal to said first end;
(c) a fastener pusher that biases said plurality of fasteners toward said first end;
(d) a movable fastener guide secured to said mounting bracket;
(e) said movable fastener guide having an engaged position and a disengaged position and said movable fastener guide comprises: a knob, a stem, a spring, a knob mounting pin, and a gate;
wherein:
(f) if in said engaged position, said movable fastener guide sequentially directs one of said plurality of fasteners toward said first end of the magazine in a manner such that one of said plurality of fasteners is prevented from completely backtracking, by mechanically interfering with a movement of said one of said plurality of fasteners that becomes misaligned; and
(g) if in said disengaged position, said movable fastener guide does not mechanically interfere with a movement of said one of said plurality of fasteners;
(h) the knob that is connected by the stem to the gate, in which said knob is rotatable along a pivot axis that extends along said stem between said knob and said gate, in which said knob and said gate rotate together between a first angular position and a second angular position, wherein said first angular position corresponds to said engaged position of said movable fastener guide, and wherein said second angular position corresponds to said disengaged position of said movable fastener guide;
(i) the spring that is mounted along said stem, between said knob and a magazine surface, such that:
(i) if said knob is rotated to said second angular position, said spring biases said knob away from the magazine surface so that the knob is forced by said spring to an extended, distal position that is spaced-apart from the magazine surface;
(ii) if said knob is actuated by being rotated to said first angular position and pressed toward said magazine surface, it thereby moves into a non-extended position that is proximal to the magazine surface; and
(j) the knob mounting pin that runs through said stem and which keeps said knob from moving away from said non-extended position, so long as the knob is not rotated to said second angular position.
