Claims

[Scope of claims for utility model registration] (1) Fixed to at least one side of a sliding door;
A thin reflector that reflects radiant energy such as light and heat rays from objects close to the door in a fixed direction along the door; An automatic door sensor comprising: a drive control section that receives a radiant energy by a radiant energy detection means, converts it into an electric signal, determines whether an object is approaching, and outputs a door opening/closing signal to a door drive section. (2) A claim characterized in that the drive control unit has a light projecting means for projecting light onto the reflector, and a radiant energy detecting means for receiving the light reflected back from an object close to the door via the reflector. Automatic door sensor according to item 1.
