An automatic rolled tissue dispensing system, which includes a housing within which is located a tissue advancing element comprising a pair of feed rollers which pull the tissue product from a roll of continuous rolled tissue product and advance the tissue to a sheet separating element comprising a pair of tearing rollers which remove individual tissue sheets from the continuous roll. A guide allows the tissue sheets discharged from the tearing rollers to be laid horizontally and stacked in a dispensing tray accessible to the user. An electric motor drives the rollers. The tearing rollers are driven through a variable clutch at a faster speed than the feed rollers, which causes the tissue to tear along its perforations in between the two sets of rollers. A first photo detecting sensor monitors the number of tissue sheets discharged from the tearing rollers, and a second photo detecting sensor monitors the presence of tissue sheets in the dispensing tray. When a pile of tissue sheets is removed from the dispensing tray, the second sensor activates the motor, which allows tissue sheets to be dispensed into the tray until the number of sheets pre-selected by the user has been counted by the first sensor.
