Abstract
PURPOSE:To detect the position of a turn table with high accuracy by using the angle of rotation detecter increasing the output in proportion to the angle of rotation of the rotary shaft for detection. CONSTITUTION:An angle of rotation detecter 150 increases its output signal so as to increase the output voltage in order while a rotary shaft 153 is rotated and repeats to increase the output in proportion to the increase of the angle of rotation by restoring the output voltage with one rotation of the rotary shaft 153. The output signal of this angle of rotation detecter 150 is transmitted to a position discriminating device 154, which detects the angle of rotation of a turn table based on the size of the output signal of the detecter 150 and transmits a discrimination signal to a controllor 136. The controllor 136 controls a flow amt. control valve 140 to execute the control of the rotary speed and stop position of the turn table. The rotation amt. of the turn table is thus known correctly and the accuracy in controlling the braking and stoppage can be improved.
