| 1. A hands-free paper towel dispenser, comprising:
(a) a cabinet defining an interior space sufficient to house a main paper towel roll, the cabinet including a front cover
that is pivotally attached thereto so that the front cover is pivotable between an open position and a closed position to
open and close the interior space;
(b) a sensing mechanism disposed entirely within the interior space of the cabinet at a location directly behind and adjacent
to the front cover so that the front cover covers the sensing mechanism when the cover is at the closed position, the sensing
mechanism being oriented toward the front cover and configured to detect an object outside of the cabinet and adjacent the
front cover without the object contacting the front cover and without any portion of the object entering the interior space,
and at least a portion of the sensing mechanism is accessible when the front cover is at the open position;
(c) a dispensing mechanism disposed within the housing for dispensing a length of towel, the dispensing mechanism including
a drive roller and a motor in driving engagement with the drive roller;
(d) control circuitry that controls operation of the sensing mechanism and the motor, controls the length of towel that is
dispensed, and provides a delay between cycles of towel dispensing; and
(e) an electric power source for powering operation of the dispenser.
