ABSTRACT:
A file sheet storing device comprising a first sheet made of a transparent material and adapted to cover one side surface of a file sheet, a second sheet made of a transparent or an opaque material and adapted to cover the other side surface of the file sheet. The first and the second sheets are connected together to form a bag-shaped cover along three edge portions leaving the remaining edge portion at least partially unconnected to provide an opening for insertion of a file sheet. The bag-shaped cover is formed along one of the three edge portions with a bonded portion for binding the cover to a book-shaped binder. The cover is further formed along the edge portion where the bonded portion is provided with a line of attachment between the first and the second sheets for preventing the file sheet from being displaced toward the edge portion where the bonded portion is formed.
