Abstract
A dispenser for dispensing sheet material including a plurality of spaced perforations may include a housing defining an interior for accommodating a source of the sheet material, and an outlet through which the sheet material may be dispensed. The device may also include a perforation sensor configured to sense perforations in the sheet material, disposed in the interior of the housing. The perforation sensor may include at least one light receptor, and at least a portion of the perforation sensor may be positioned in the housing to contact sheet material traveling from the source to the outlet, thereby spreading perforations in the sheet material.
