Claim Text:
1. Paper sheet material dispenser apparatus for dispensing paper sheet material from a roll of paper sheet material having an existing tail portion with a leading end, said dispenser apparatus comprising, in combination: a housing having a housing interior and defining an opening communicating with said housing interior; a roll support within said housing interior for rotatably supporting the roll of paper sheet material; a rotatable sheet material support roller for receiving paper sheet material from the roll of paper sheet material, said sheet material support roller having a cylindrically-shaped outer peripheral surface; a DC motor for receiving DC power from a DC power source, said DC motor having a rotatable motor shaft connected to said sheet material support roller by a one way clutch structure for exerting a driving force on said sheet material support roller rotating said sheet material support roller in a rotational direction advancing said paper sheet material and moving the tail portion relative to said opening toward a position with the leading end thereof disposed either within said housing interior or externally of said housing, said one way clutch structure allowing continued rotation of the support roller in said rotational direction after rotation of the motor shaft has stopped; and a dynamic braking structure operatively associated with said DC motor responsive to termination of DC power from the DC power source to the DC motor to electrically brake said DC motor by reversing the direction of DC current applied to said DC motor and place the tail portion at said position.
