Abstract
An index apparatus for a rotary table comprises first and second index plates connected to a driving motor. First and second switches are provided for generating first and second signals in cooperation with the first and second index plates each time the rotary table is rotated a unit angle. Third signal generating circuit is connected to the first and second switches for generating third signals, each of which is generated when the second signal is generated and disappears when the first signal disappears. Control circuit is provided for counting the number of the third signals to thereby stop the rotary table at a desired angular position when the number reaches to a preset number.
