In addition, the central control unit 146 is connected to the input interface 130 and changes the setting data, transmits and receives the setting data, and the like based on the input from the input interface 130. The control circuit 140 further includes a buzzer 148, and notifies the operator of the completion or error of a predetermined operation by a voice.

The other electric screwdriver 100 'which is communicably connected to the electric screwdriver 100 is the same as the electric screwdriver 100 described above, and corresponding symbols are attached to corresponding constituent elements. Through these electric screwdrivers 100 and 100 ', an electric screwdriver system (electric power tool system) which is communicably connected to each other by the respective communication sections 144 and 144' is constituted.

The operation at the time of transmitting and receiving the setting data between the electric screwdrivers 100 and 100 'in the aforementioned electric screwdriver subsystem composed of two electric screwdrivers 100 and 100' will be described below with reference to Fig. 3.

First, the power of the electric screwdriver 100 on the transmission side is turned on to start control (S100), and the input interface 130 is operated to shift the electric screwdriver 100 to the transmission mode (S112). When transitioning to the transmission mode, changes in the setting data, driving of the electric motor 112, and the like are temporarily impossible. Next, a model of the driver 100 'on the receiving side as the transmission target is selected (S114). In some cases, the communication protocol that can be received varies depending on the model. Therefore, the model of the electric driver 100 'on the receiving side is selected in advance, and data communication is performed using a communication protocol that conforms to the electric driver 100' on the receiving side. In addition, although the number of models of electric screwdrivers continues to increase with each development of a new electric screwdriver, in this case, it is updated and set in the control circuit at any time. 140 types of electric screwdrivers can be selected, but also new models can be communicated. Next, the setting data is read from the memory (first information recording means) 142 of the control circuit (first control circuit) 140 of the electric driver body (first power tool body) 110 on the transmission side (S116). The control circuit 140 on the transmission side has a function of selecting the setting data to be transmitted from the read setting data based on the input from the input interface 130 (transmission data selection means), and only transmitting a part of the setting data Here, select the setting data to be transmitted (S118). In addition, if the receiving type electric screwdriver 100 'and the transmitting type electric screwdriver 100 are different models, the setting data of the transmitting side may include setting data of the electric screwdriver 100' which cannot be set on the receiving side. The setting data that cannot be set on the receiving side is automatically removed from the setting data that is the object of transmission. When the selection of the setting data to be transmitted is completed, the control circuit 140 on the transmitting side encodes the setting data in a manner corresponding to the model of the electric driver 100 'on the receiving side as the transmission target (S120), and transmits the setting data through communication. Transmission (first communication means) 144 (S122).

The electric screwdriver 100 'on the receiving side is powered on to start the control (S150) before the transmission of the setting data from the control circuit 140 on the transmitting side (S122), and the input interface 130' is operated to operate the electric screwdriver. 100 'shifts to the reception mode (S152). When shifting to the reception mode, changes in the setting data and driving of the electric motor 112 'are temporarily impossible. When the receiving mode is set and the setting data transmitted from the control circuit 140 on the transmitting side is delivered, the driving program on the receiving side is built in the electric screwdriver body (second electric tool body). The communication unit (second communication means) 144 'of the control circuit (second control circuit) 140' of the mobile terminal receives the transmitted setting data (S154). The control circuit 140 'on the receiving side returns the received setting data from the communication unit 144' to the control circuit 140 on the transmitting side when the setting data has been received (S156) (S158).

The control circuit 140 on the transmitting side receives the setting data returned from the control circuit 140 'on the receiving side after the setting data is transmitted (S124) (S126). When reception of the returned setting data is completed (S128), the control circuit 140 on the transmitting side compares the transmitted setting data with the returned setting data, and determines whether the transmission and reception of the setting data is properly performed (S130). That is, when there is no difference between the transmitted setting data and the returned setting data, the control circuit 140 'on the receiving side judges that the setting data is appropriately received. As a result of this determination, if it is determined that the appropriate setting data is being communicated, the control circuit 140 on the transmitting side transmits an OK signal (S132), and at the same time, the sound indicating the intention is sounded through the buzzer 148 and used for The reporter informs that appropriate data communication has been performed (S134). On the other hand, if it is determined that the communication of the appropriate setting data has not been performed, the NG signal is transmitted (S136), and the sound indicating the intention is sounded through the buzzer 148 to inform the user that the appropriate Data communication (S134). As a result, a series of processing related to the setting data transmission in the control circuit 140 on the transmission side is completed (S140).

The control circuit 140 'on the receiving side receives the OK signal or the NG signal transmitted from the control circuit 140 on the transmitting side after returning the setting data (S160). When receiving an OK signal, the system will indicate The intended sound is transmitted through the buzzer 148 '(S164), and the received setting data is decoded (S166). The control circuit 140 'on the receiving side has a function of selecting setting data to be written into the memory (second information recording means) 142' from the setting data received through the input from the input interface 130 '(received data) (Selection means), and when a part of the received setting data is written into the memory 142 ', the setting data to be written is selected here (S168). Next, the selected setting data is written into the memory 142 '(S170), and when the writing is completed, a sound indicating the intention is sounded through the buzzer 148' (S174). On the other hand, when the NG signal is received, a sound indicating the intention is transmitted through the buzzer 148 '(S172). Thereby, a series of processing related to the setting data reception in the control circuit 140 'on the receiving side is completed (S176). The setting data written in the memory 142 'becomes effective on the control circuit 140' on the receiving side, and the motor driver body can be driven and controlled by the same setting as the control circuit 140 on the transmitting side.

The other operations when transmitting and receiving the setting data between the electric screwdrivers 100 and 100 'in the electric screwdriver subsystem composed of the two electric screwdrivers 100 and 100' will be described below with reference to Fig. 4.

The communication unit 144 'of the control circuit 140' on the receiving side has a function (transmission request function) for transmitting a transmission request signal for requesting transmission of setting data to the control circuit 140 on the transmitting side. Transfer here After the reception mode, the transmission request signal is transmitted together with the equipment information of the driver 100 'on the receiving side (S253). The control circuit 140 on the transmitting side receives the transmission request signal and device information from the control circuit 140 'on the receiving side (S211), and automatically shifts to the transmission mode (S212). Then, the model of the electric driver 100 'on the receiving side is determined based on the received machine information (S214). The control circuit 140 'on the receiving side may also cause the transmission request signal to include transmission data specifying information for specifying the setting data requested by the control circuit 140 on the transmitting side. When the transmission request signal includes transmission data designation information, the control circuit 140 on the transmission side selects the specified transmission data from the setting data recorded in the memory 142 based on the transmission data designation information, and only selects the selected transmission. The data is transmitted to the control circuit 140 ′ on the receiving side through the communication unit 144. The steps S216 to S240 of the control circuit 140 on the transmitting side and the steps S254 to S276 of the control circuit 140 'on the receiving side shown in FIG. 4 are the same as those shown in FIG. 3, so the detailed description here is omitted. . In addition, when transmitting the transmission request signal, it is also possible to search for the electric screwdriver 100 on the transmission side, and when a plurality of electric screwdrivers 100 are retrieved, one of the electric screwdrivers 100 is selected, and only the transmission request signal is transmitted to the electric motor.
