Abstract
Abstract A recorder has functions of optically reading image information drawn on a board (record medium), converting the image information to an electrical signal, recording the image information on a record sheet by record means, optically reading a document sheet separately, and outputting the document image onto the board. Further, another image information may be drawn over the image information on the board, and the composite image may be read and recorded on a record sheet.
