Abstract: An electrically drivable device includes a device body including an actuator and a handle attachable to and detachable from the device body. The handle includes a connector separably connectable with the device body, a pressure receiver displaceable in response to a gripping force with which the user grips the handle, a magnet control mechanism configured to operate a permanent magnet in conjunction with the displacement of the pressure receiver, and a frame holding the pressure receiver in such a manner that the pressure receiver is displaceable, and containing the magnet control mechanism. The device body includes a magnetic sensor configured to, in response to the pressure receiver being displaced with the handle attached to the device body, detect magnetism that the permanent magnet applies through the connector.

Abstract: An electric device includes: an electric circuit; a power supply circuit configured to feed electric power to the electric circuit and stop the feed; and a housing containing the electric circuit and the power supply circuit. The power supply circuit is configured to, in response to a first operation performed from outside the housing while the power supply circuit is in an OFF state, the OFF state being a state in which the battery feeds no electric power to the electric circuit, transition to an ON state, the ON state being a state in which the battery continuously feeds electric power to the electric circuit even after an end of the first operation, and in response to a second operation performed while the power supply circuit is in the ON state, transition to the OFF state.
