摘要： A spring-type fastener driving tool includes a plunger having a blade that drives in fasteners, a spring that urges the plunger downwards and is capable of being compressed upwards, a spring compression mechanism unit that includes a drum that causes the plunger to move in a compression direction of the spring based on rotational force of a motor, a reduction mechanism unit, and a one-way clutch than prohibits reverse rotation of the motor. Reverse rotation of the drum due to the urging force of the spring is prevented by providing the one-way clutch between an input side rotating shaft of the reduction mechanism unit and a rotation output shaft of the motor.

摘要： When the plunger is a game moved to a prescribed position Ph of an initial state on the upper dead point side by the drive force of the motor after the plunger is moved to the lower dead point side, the controller of a spring driven-type fastener driving tool reduces the rotational speed of the motor to a prescribed value or less based on the detection signal of the operation detection switch and then stops the slowed down motor. In order to achieve this, the plunger is stopped at a stop position of an initial state that is as close as possible to an upper dead point side drive start position and is subjected to a strong compression force by the drive spring.

摘要： 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).

摘要： A controller 50 has a single-driving mode/continuous-driving mode changeover switch 233 for performing fastener driving operation in a single driving mode or a continuous driving mode. In a case where the single-driving mode/continuous-driving mode changeover switch 233 instructs a single driving mode, the controller 50 causes a driver blade 3a to perform fastener driving operation when both a trigger switch 5 and a push lever switch 22 are switched, by switching operation, from the one switch status to the other switch status (e.g., the ON status). Consequently, fastener driving operation is made possible regardless of sequence of actuation of the trigger switch 5 and the push lever switch 22.

摘要： An electric driving machine has a motor for rotating a flywheel, power transmission means for converting rotational drive force of the flywheel into rectilinear drive force and transmitting the rectilinear drive force to an actuator which fires a fastener, and engagement/disengagement means which transmits the rotational drive force of the flywheel to a driver blade or interrupts transmission of the rotational drive force. The electric driving machine is provided with a second switching element connected in series with the engagement/disengagement means and a third switching element connected in shunt with the engagement/disengagement means. When a push lever switch is in an OFF position where driving of a fastener is not ready, the third switching element is held in an ON state.

摘要： Even when a transient decrease has arisen in a battery voltage VBAT of a battery pack at startup of a motor that drives a flywheel, a power terminal Vcc and a reset terminal RES (or an input terminal IN of a reset IC) of a microcomputer are replenished with a normal voltage by the voltage accumulated by a capacitor of the backup power circuit, and hence a controller can maintain normal operation without involvement of faulty operation. As a result, even the battery pack whose battery has a smaller amount of remaining energy can be effectively utilized as the power source of an electric driving machine.

摘要： An electric fastener driver having a compact size and simple construction. A driver segment provided with a rack is movably disposed in a housing. A flywheel is driven by a motor. A drive shaft is concentric with and integral with the flywheel. A coil spring is fixed to the drive shaft. A driven rotor is coaxial with the drive shaft and has one end portion serving as a spring seat portion positioned within the coil spring. A pinion is disposed at the driven rotor and is meshedly engaged with the rack. An urging section is disposed within the driven rotor. A ball is movably disposed in a through-hole formed in the driven rotor for urging an end portion of the coil spring by the urging section. A solenoid controls a protruding amount of the ball from the surface of the driven rotor.
