Note sheets, having opposite free and adhesive edges, removably attached to documents are individuated and scanned. A document-edge bearing device shifts away from a document to allow the document's edge nearest its note sheet's free edge to droop under its own weight and open a free-edge-document gap. A scanning control unit situates into the gap a note-wedging guide component of a pivotal scanning device carried on a note-targeting platform, and having a note-sheet scanner and rollers for moving a removable note sheet across the scanner, both to peel the note sheet off its document, and to scan the note sheet. In a note-sheet presence/position detecting mechanism, document-edge pressing sliders wrinkle a document, and a control-linked sensor detects a shading-difference-originating gap between the free edge of any removable note sheet, and the document to which it is attached, to determine physical presence and document-relative position of the note sheet.
