Abstract
Switch operation mechanism includes a handling lever pivotally connected to a portion of a handle, a generally-fan-shaped actuating member pivotally connected at its pivot portion to the handle in such a manner that the actuating member is pivotable in response to operation, by a human operator, of the handling lever, and a noncontact reed switch for turning on or off a cutter-driving electric motor in accordance with an ON/OFF state of the noncontact reed switch. The ON/OFF state of the noncontact reed switch is determined in accordance with pivoting movement, toward or away from the switch, of the actuating member responsive to the operation of the handling lever. With such arrangements, the switching operations of the operation mechanism can be performed accurately in a stable manner.
