Abstract
A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.
Claims23
A battery pack comprising:
- a battery;
- a connector configured to be detachably coupled to a tool main body, the tool main body including a motor, the motor being configured to be driven by an electric power supplied from the battery via the connector coupled to the tool main body;
- a communication circuit configured to wirelessly transmit a notice inputted to the communication circuit without specifying a recipient or with the recipient specified;
- and
- a communication controller configured to be set to a first mode and a second mode, the communication controller set to the first mode being configured to transmit a first notice via the communication circuit at a first cycle after the battery pack has been coupled to the tool main body, the first notice including a first type of information, the communication controller set to the second mode being configured to transmit a second notice via the communication circuit at a second cycle, the second notice including a second type of information but excluding the first type of information, and the second cycle being different from the first cycle.

An electric power tool, comprising:
- a first communicator, including:
- a communication circuit configured to wirelessly transmit a notice inputted to the communication circuit without specifying a recipient or with the recipient specified;
- and
- a communication controller configured to be set to a first mode and a second mode, the communication controller set to the first mode being configured to transmit a first notice via the communication circuit at a first cycle after the electric power tool is powered, the first notice including a first type of information, the communication controller set to the second mode being configured to transmit a second notice via the communication circuit at a second cycle, the second notice including a second type of information but excluding the first type of information, and the second cycle being different from the first cycle.

A method for wirelessly transmitting a notice from a communicator, the method comprising:
- setting the communicator to a first mode, the communicator being operated based on an electric power of a battery, the battery and the communicator being provided to a battery pack, the battery pack being configured to be detachably coupled to a tool main body, the tool main body including a motor, the motor being configured to be driven by an electric power of the battery;
- wirelessly transmitting a first notice from the communicator without specifying a recipient or with the recipient specified, in response to the communicator being set to the first mode, the first notice being wirelessly transmitted at a first cycle after the battery pack has been coupled to the tool main body, and the first notice including a first type of information;
- setting the communicator to a second mode;
- and
- wirelessly transmitting a second notice from the communicator without specifying a recipient or with the recipient specified, in response to the communicator being set to the second mode, the second notice being wirelessly transmitted at a second cycle, the second notice including a second type of information but excluding the first type of information, and the second cycle being different from the first cycle.
