That is, after a single launch operation, with the trigger 103a pulled, the driver guide 141 pressed against the workpiece is released, and the driver guide 141 is pushed again to other parts of the workpiece. By hitting, a continuous launching operation for performing the next nailing operation is performed. In other words, in a normal launching operation, one nail is launched for each operation on the trigger 103a. In a continuous firing operation, a plurality of nails are launched with the trigger 103a being operated once. .
- the magnetic sensor 150 measures the position of the crankshaft 115a. Thereby, the magnetic sensor 150 measures the position of the crankshaft 115a only before the start of the first launching operation among the plurality of launching operations.
- the magnetic sensor 150 may measure the position of the crankshaft 115a at the timing 3 when the driver guide 141 is pressed before each launch operation. In the continuous launching operation, the magnetic sensor 150 may measure the position of the crankshaft 115a at the timing 2 and the timing 3.
- the position of the compression piston 133 is detected by measuring the position of the crankshaft 115a. When the compression piston 133 is located at a position other than the bottom dead center, the control device 109 drives the electric 111 motor to move the compression piston 133 to the bottom dead center.
- the control device 109 moves the compression piston 133 so as not to compress the air in the compression chamber 131a. That is, the compression piston 133 is moved to the bottom dead center without passing through the top dead center.
- the control device 109 reversely rotates the electric motor 111 to move the compression piston 133 to the bottom dead center.
- the control device 109 rotates the electric motor 111 in the normal direction to move the compression piston 133 to the bottom dead center.
- the compression piston 133 is moved to the bottom dead center without passing through the top dead center.
- the return operation described above includes a first return operation for moving the compression piston 133 to the bottom dead center at a time and a second return operation for intermittently moving the compression piston 133 while the compression piston 133 is moved to the bottom dead center. It is configured to be selectable. That is, in the first return operation, the compression piston 133 is accelerated and then moved at a constant speed, and then decelerated and stopped at the bottom dead center. On the other hand, in the second return operation, the compression piston 133 repeats constant speed movement and stop, and is finally stopped at the bottom dead center. Therefore, in the second return operation, the compression piston 133 is moved intermittently.
- the first return operation moves the compression piston 133 to the bottom dead center. That is, the return operation at the timing 2 or the timing 3 is performed by the first return operation.
- the user starts the launching operation it is necessary to quickly move the compression piston 133 to the bottom dead center, and it is reasonable to move the compression piston 133 to the bottom dead center by the first return operation.
- the compression piston 133 is moved to the bottom dead center by the second return operation. That is, the return operation at timing 1 is performed by the second return operation. It is unclear whether or not the user immediately starts the launching operation simply by mounting the battery pack 110. Therefore, when the battery pack 110 is mounted, the return operation is performed by moving the compression piston 133 to the bottom dead center by the second return operation. Thereby, the user is notified that the return operation is being performed by the vibration generated by the intermittent movement of the compression piston 133.
- This second return operation is an implementation configuration example corresponding to “notification means” in the present invention.
- the LED 107 irradiates the tip region of the driver guide 141 during the launching operation.
- the control device 109 causes the LED 107 to blink. This notifies the user that the return operation is being performed.
- the configuration is not limited to the configuration in which the LED 107 blinks, and the configuration may be such that the color of light emitted by the LED 107 is changed between the launch operation and the return operation.
- This LED 107 is an implementation configuration example corresponding to “notification means” in the present invention.
- the compression piston 133 since the compression piston 133 is moved to the bottom dead center before starting the launching operation, the compression amount compressed by the compression piston 133 with respect to the air is made constant in the launching operation. Can do. Thereby, the driving tool to be driven can be driven at a predetermined speed for each driving operation.
- the magnetic sensor 150 does not need to directly measure the compression piston 133. That is, it is not necessary to directly measure the position of a member surrounded by the compression cylinder 131 or the like like the compression piston 133. Therefore, the position of the compression piston 133 can be easily detected by measuring the positions of the crankshaft 115a and the motor shaft of the electric motor 111.
- the return operation is performed, so that the compression piston 133 can be positioned at the bottom dead center before performing the launching operation.
- the battery pack 110 may be out of charge, or the battery pack 110 may be unintentionally removed. Even in such a case, when the battery pack 110 is mounted, the compression piston 133 can always be moved to the bottom dead center.
- the compression piston 133 can be moved to the bottom dead center without the compression piston 133 passing through the top dead center. Therefore, when moving the compression piston 133, the air in the compression cylinder 131 is not compressed. Therefore, it is possible to prevent the nail from being unintentionally driven out when the compression piston 133 is moved.
- the LED 107 that is a notification unit and the second return operation among the return operations are provided, so that the user can be notified that the return operation is being performed.
