Abstract

In a door sensor, a projector has linear light emitting surfaces continued in a longitudinal direction and projects light to traverse a doorway. A light receiver is provided with a light receiving lens which receives and collects the light projected from the projector, and an imaging element which receives the light collected by the light receiving lens. As the imaging element, a linear imaging element wherein a plurality or light receiving elements are arranged in a one-dimensional direction, is used. A control section judges existence of an obstacle at the doorway, based on a signal outputted from the light receiver.
