Abstract
A dispenser for sequentially dispensing rolls of sheet material is described. The dispenser has an automatic transfer mechanism for transferring a reserve roll into a dispensing position once a primary roll has been depleted. The automatic transfer mechanism includes a diameter sensing member and a blocker rotatably coupled to the dispenser housing and biased to rotate in a opposite directions. The diameter sensing member and block cooperate with one another in order to block the reserve roll from contacting a drive roller until the primary roll has been depleted. The reserve roll held in the dispenser by two pivoting arms that are biased to rotate towards the drive roller.
