Abstract
An electric driving machine includes a remaining fastener sensorwhich detects the amount of fasteners (e.g., nails) remaining, in an aligned and held manner, in a magazineand 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 circuitwhich outputs a control signal (a signal of level) for controlling control means (, and other means) in accordance with an input of the residual-quantity signal (a switch-on signal) generated by the remaining fastener sensor; and a delay circuitfor delaying the remaining signal (the ON signal) generated by the remaining fastener sensorby a predetermined period of time (e.g., 20 milliseconds) and inputs the thus-delayed remaining signal to the remaining fastener detection circuit().
