<p>PROBLEM TO BE SOLVED: To provide a slip sheet picture book which prevents braille from being crushed, being transferred to another braille form brought into contact the braille to produce ruggedness and prevents the curling/peeling or generation of wave due to adhesion unevenness after adhesion from occurring.SOLUTION: By changing compressive pressure into about 0.5 ton/m on a center part of a book and about 20 ton/m on a peripheral part thereof, it is prevented that braille is crushed and the braille is transferred to another braille form brought into contact with the braille. Therefor, high-hardness material is used for a compression part 4-1 and a cushion 4-2 is made of soft material and is formed with dimensions about 10 mm smaller than the width and height of the book and a thickness thinner than the thickness of the book. Further, the adhesive surface is provided with softness and is formed of striped shape by adhesive coating, by thickening coating thickness, adhesion of a joint part is permitted without increasing the total coating amount and, as the result, peeling due to opening and closing of the book or wave and curl does not occur on the text.</p> |
