Abstract
PURPOSE: To provide an automatic door opening and closing system in which opening and closing of the automatic door is achieved by projecting a light beam toward the body of a passenger, converting the reflected light into an electric signal, calculating the same in intergrating and differentiating circuits and comparing the obtained value with a pre-set value, whereby the door can be operated correctly without malfunction.
