An automatic dispenser for dispensing a product stored therein 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 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.
A paper towel dispenser arranged to both store a supply of paper and automatically dispense at least a portion of said supply of paper, said dispenser comprising a housing with an outer surface, and an active IR sensor system for detecting presence of a possible user, said IR sensor system including at least one IR emitter having an active emitting portion and at least one IR receiver having an active receiving portion, wherein said outer surface is positioned on the lower side of said dispenser housing facing generally downwards, and wherein said outer surface at the lower side of said dispenser housing, in which said at least one emitter and said at least one receiver are positioned, being directly adjacent a lateral discharge opening of said dispenser on the lower side of said dispenser and said sensor system comprising at least two IR emitters and at least three IR receivers, wherein one receiver is located on each lateral side of an emitter such that the emitters and receivers are in the order receiver-emitter-receiver-emitter-receiver in a lateral direction across the dispenser.
