Abstract: A driving tool includes a main body, a trigger, a contact member and a control unit. The main body has a combustion chamber configured to be filled with fuel and compressed air. The trigger is configured to operate an ignition device to combust a mixture of the fuel and the compressed air filled in the combustion chamber. The contact member is brought into contact with a driving target member to enable an operation of the trigger. The control unit is configured to start an injection of the fuel when the contact member is turned on, and to complete an injection of the air after the trigger is turned on.

Abstract: A safety device includes: a tool which performs a predetermined operation through an operation of an actuator; a mounting tool worn by a user operating the tool; a transmission unit which is provided in one of the tool or the mounting tool, and transmits a wireless signal in which a transmission direction is set to have high directional characteristic with respect to a certain direction; a reception unit which is provided in the other of the tool or the mounting tool, and receives the wireless signal transmitted by the transmission unit; and a controller which controls the tool on a condition that the reception unit recognizes the wireless signal.

Abstract: A fastener driving machine includes an actuator which injects a fastener to a driving target object, a controller which controls an operation of the actuator, and a sensor which detects a physical quantity changed by a contact with the driving target object. The controller controls the actuator based on the physical quantity detected by the sensor.

Abstract: A driving tool includes a combustion chamber, a cylinder, a valve and a control unit. Fuel and compressed air are supplied into the combustion chamber. The cylinder is configured to movably store a piston which is driven by combustion pressure at a time of igniting a mixture of the fuel and the compressed air filled in the combustion chamber. The valve is configured to open and close a passage through which the compressed air is supplied into the combustion chamber. The control unit is configured to control the valve to supply the compressed air into the combustion chamber when the control unit determines that a return of the piston is completed.
