PROBLEM TO BE SOLVED: To shift to an active mode without requiring a user to operate a main switch, when a control circuit is in a sleep mode, in an electric equipment system.SOLUTION: A power tool system is composed of a battery pack 10, a power tool 30, and an adaptor 60. These portions are respectively provided with control circuits 20, 40, and 70. The adaptor 60 outputs a signal Si to the control circuit 70 to shift to an active mode when receiving a signal So from an external equipment 80, and the control circuit 70 outputs a signal S1 to the control circuit 40 to shift to the active mode. The control circuit 40 outputs a signal S4 to the control circuit 20 to shift to the active mode when shifting to the active mode. |
