An apparatus for detecting door movement data in an automatic door system is improved in that an opening-direction sensor and a closing-direction sensor are provided on a horizontal member of a slide door frame, while a slide door is provided with a dog having a plurality of actuating portions adapted to switch ON or OFF the opening-direction sensor and the closing-direction sensor as arrayed at an interval in the direction of sliding, so that the opening direction sensor and the closing direction sensor may be switched ON and OFF repeatedly as the door is moved in the opening or closing direction. |
