CA 2614720

An automatic dispenser for dispensing a product stored in the dispenser, which includes an active IR sensor system for detecting a user. The IR system includes emitters and receivers which are mounted so that each IR emitter's active emitting portion protrudes outwardly from an outer surface of the housing and each IR receiver's active receiving portion is recessed behind that outer surface, such that the outward protrusion of the active receiving portion from the outer surface of the housing is less than the outward protrusion of the active emitting portion. The outer surface of the housing in question which is preferably at the bottom of the housing next to the discharge outlet. This arrangement allows a reliable and accurate IR reception field to be obtained with a shape more suited to expected user positioning.

Distributeur automatique pour distribuer un produit stocké dans le distributeur et qui comprend un système actif de capteurs IR pour détecter un utilisateur. Le système IR inclut des émetteurs et des récepteurs montés de façon à ce que la partie active de chaque émetteur IR dépasse vers l~extérieur d~une surface extérieure du boîtier et que la partie active de chaque récepteur IR soit en creux derrière cette surface extérieure, de manière à ce que le dépassement extérieur de la partie active de réception de la surface extérieure du boîtier soit inférieure au dépassement extérieur de la partie active d~émission. La surface extérieure dudit boîtier est, de préférence, au bas du boîtier, à côté de la sortie de décharge. Cette disposition permet d~obtenir un champ de réception IR fiable et précis et d~une forme plus adaptée au positionnement attendu de l~utilisateur.
