Abstract
A control unit is adapted to perform a process related to an electric power tool, based on sound input to a microphone. The control unit performs a process related to the electric power tool, based on a result of subjecting input sound to a sound recognition process or a result of subjecting the sound to sound analysis. When a user operation switch is in an on state, the control unit does not perform a sound recognition process, and, when the user operation switch is in an off state, the control unit performs a sound recognition process. Further, when the electric power tool is not in a state of being gripped by the user, the control unit does not perform a sound recognition process, and, when the electric power tool is in a state of being gripped by the user, the control unit performs a sound recognition process.
