PROBLEM TO BE SOLVED: To facilitate understanding of a manuscript content by superposing contents of front and rear surfaces of a manuscript by mats for projecting it by using a language, a sign and a symbol so that the front and rear surfaces of the manuscript are covered with the mats, engaging parts of the mats, closing so that non-engaging parts are turned over, and attaching protrusion and recess parts for headings. SOLUTION: A language, a sign and a symbol having meanings similar to a manuscript are previously converted and described on mats 1, 2 provided to cover front and rear surfaces of the manuscript, the mats 1, 2 are compositely combined so that the languages, the signs and the symbols are easily understood similarly to the manuscript. Such mats are formed by using arbitrary materials such as transparent, translucent, colored an the like. In this case, the parts of the mats are engaged and closed so that non-engaged parts are turned over. Protrusion and recess parts 3, 4 for headings are formed as deviate at positions at respective mats 1, 2. When such mats are used, a language and knowledge deficient person can easily understand the manuscript content.
