Abstract
Abstract By combining a pad having a repositionable adhesive with a carbonless imaging system, multiple copies of a writing on the top sheet of the pad are provided. These features have application in pads for memos, inter-office correspondence, and notes. A user may select the desired set of copies by removing the required number of sheets from the pad. If a divider is provided with each pad, e.g. a cardboard or a hard insert sheet, the multiple pages are imaged before they are removed from the pad by inserting the divider into the pad after counting the appropriate number of sheets to be copied. Thus, the divider prevents copying and imaging throughout the entire pad.
