Abstract
Disclosed is a backpack type operating unit, which includes a backpack frame having a front portion and a left lateral side portion, an operating device and a motive power source for driving the operating device. The motive power source and the operating device is mounted on the backpack frame, and the front portion of the backpack frame faces toward a forward direction and the left lateral side portion facing toward a leftward direction, in which the forward direction and the leftward direction are perpendicular to each other and lying in a common horizontal plane. The operating unit comprises a supporting member mounted on the left lateral side portion of the backpack frame, a substantially longitudinal arm having two opposite end portions, the arm being pivotably mounted on the supporting member at one of the end portions so that the arm can be pivoted between a first pivotal position in which the arm points vertically upward with respect to the horizontal plane and a second pivotal position in which the arm points toward an inclined direction between the forward direction and the leftward direction, and mechanism provided on the arm for operating the motive power source.
