  • Publication number: 20130245789
    Abstract: An electric tool includes a motor, a light having a function in addition to a data transmission, a switch configured to switch power supply to the light in accordance with a user operation; and a control unit. Upon a switch is switched from OFF to ON, the light is blinked at a frequency above the human-sensible range on the basis of data such as the usage history data of the electric tool. An average of the blinking frequency of the light is approximately 4,800 Hz when a bit rate is set to 9,600 bps, for example. Further, an average of a duty ratio of a drive signal of the light during blinking is approximately 50%.
