Patent 7357304 was granted and assigned to NCR on April, 2008 by the United States Patent and Trademark Office.
A security means comprises a spray tray; a dispenser slot positioned so as to dispense media into the spray tray; and a security cover positioned to cover said spray tray and slot. The cover is arranged so as to cause a sweep member to sweep past the dispenser slot and thus dislodge any foreign body adjacent the slot, when the cover is moved between closed and opened positions.
