Abstract:
A dispenser for dispensing flexible sheet material, comprising:a support for rotatably supporting a roll of sheet material; a feed mechanism for advancing the sheet material from said roll; a motor for driving the feed mechanism; a structure defining a discharge chute of the dispenser downstream of said feed mechanism; a sensor for detecting the presence and absence of sheet material in said discharge chute and outputting respective first signals indicative thereof; a proximity sensing system including an RF antenna, for detecting the presence of a user's hand in close proximity to the dispenser and outputting a second signal indicative thereof; and a control device for receiving said respective first signals and second signal and controlling said motor to selectively drive said feed mechanism in response thereto; wherein, said sensor is mounted on a first printed circuit board mounted on said structure adjacent to said discharge chute, and said antenna is mounted on a second printed circuit board mounted on said structure and positioned in overlying relation to the first printed circuit board.
