Abstract

Official abstract text for this publication.

A detecting unit ( 14 ) forms a plurality of detection spots arranged two-dimensionally on a floor surface near a door panel ( 12 ). Each detection spot is capable of detecting a human or an object by infrared light independently from other detection spots. Region distinguishing means ( 30 ) distinguishes a region formed by plural ones of the said detection spots that have detected the human or object. Person's movement judging means ( 44 ) judges the direction in which the distinguished region moves. A signal which causes a door panel ( 12 ) to be opened is supplied to a door controller ( 34 ) only when the direction of movement of the distinguished region is the direction toward the door panel.
