A moving image reproducing apparatus is provided with CPU 8 and a displaying unit 7. Each tubular portion is hollow and includes a blade element at a distal end. The apparatus includes means for precisely proportioning percentages of the regulated dc source voltage to the dc series-connected electronic devices irrespective of production variations in operating parameters of the electronic devices andor drift of the electronic devices. A latching hook is formed on the second air duct to be selectively latched to one of the latching slots. The tip is rotated and reciprocated ultrasonically at the same time so that tissue is fragmented by the combined motion of a fragmenting surface perpendicular to the surface and at an angle to the surface many times during a single revolution or part of a revolution.
