Patent attributes
A document reading apparatus has a slit along one side of a document support platen of a glass plate to insert one part of an opened book as a document to be read. An insertion pocket forming a recessed space contiguous with the slit and inclined diagonally is provided in the apparatus. A lid is operable between open and closed positions exposing and covering the slit. In the open position, one part of a book can be inserted into the slit with a page in the other part of the book being in intimate contact with the platen, while in the closed position, a sheet as a document can be placed at a proper position on the platen by contacting one side of the sheet to a rim of the lid. This apparatus prevents a problem of image deformation and black image in print output when reading the book.
