An electric driving machine includes a remaining fastener sensor 257 which detects the amount of fasteners (e.g., nails) remaining, in an aligned and held manner, in a magazine 2 and which generates a residual-quantity signal (a signal showing depletion of fasteners) when the amount of remaining fasteners has decreased to a predetermined level or less; a remaining fastener detection circuit 406 which outputs a control signal (a signal of level 0) for controlling control means (299, 283, and other means) in accordance with an input of the residual-quantity signal (a switch-on signal) generated by the remaining fastener sensor 257; and a delay circuit 401 for delaying the remaining signal (the ON signal) generated by the remaining fastener sensor 257 by a predetermined period of time (e.g., 20 milliseconds) and inputs the thus-delayed remaining signal to the remaining fastener detection circuit 256 (406).
