<p>PURPOSE:To need no cam plates and no cam contactors, by connecting rotary encoders to the rotary shafts of an inverter and a main handle unit. CONSTITUTION:When the handle 7 of an inverter is operated according to a pitch formed on the outer peripheral surface of a star gear 9, then according to the rotational angle of an inverter rotary-shaft 8 in its case, from a rotary encoder 12, the output of pulse signal is generated. Besides, when the handle 1 of a main handle unit is operated along the pitch formed on the outer periphery of its star gear 3, then according to the rotational angle of a main handle rotary-shaft 2, from a rotary encoder 6, the output of pulse is generated. Then, by a sequencer, based on the output pulse from the rotary encoders 12, 6, control command signal is applied to a motor for driving a cam shaft.</p> |
