摘要： A fastener driving tool (1) providing a prolonged durability and stabilized fastener driving operation. The tool (1) includes a housing (2), a motor (31) disposed in the housing (2), a plunger (63) disposed in the housing and driven by the motor (31) for driving a nail (IA), a cable member (52) connected to the plunger (63) for pulling the plunger (63) from its bottom dead center where the nail is driven into a workpiece to a top dead center, and a drum (51) driven by the motor (31) for winding the cable member thereover. A cable member (52) is wound over the drum by a length greater than a linear distance between the bottom dead center and the top dead center. The cable member (52) is flexed or deflected due to own weight when the plunger is at the bottom dead center.

摘要： When a main switch (12) is turned ON, an electric operating machine (1) is put in the standby mode. With a trigger (13) being pulled in the standby mode, a power supply circuit (16) applies a voltage to a drive part (30). The power supply circuit (16) adjusts the voltage applied to the drive part (30) for a voltage corresponding to the pulling rate of the trigger (13). When the current running toward the drive part (30) exceeds the rated value of the drive part (30), the power supply circuit (16) automatically stops power supply to the drive part (30). On the other hand, when the output voltage of a battery (50) drops and the battery (50) is put in an overdischarge state, power supply to the drive part (30) is automatically stopped. When it is detected that the battery (50) undergoes an abnormal event, power supply to the drive part (30) is automatically stopped.
