PURPOSE: To copy plural documents onto plural paper sheets by one time operation by providing on the surface of a sheet main body retaining pieces to fix paper sheets.

CONSTITUTION: A retaining piece 2 is fitted to the surface of a sheet main body 1, and a paper insertion opening 3 is formed on one side of the retaining piece 2, and paper sheets 5 to be copied are inserted into the paper insertion opening 3, and fixed on the sheet main body 1 by means of the retaining piece 2. The sheet main body 1 furnished with the paper sheets 5 is delivered into a copying machine from a hand insertion paper feed position, and plural paper sheets are copied once. This sheet main body 1 uses a heat resistant sheet. Also, one side of a retaining piece 2 cut into a belt shape is bonded at a free interval, and the insertion opening 3 is formed on the other side. Also, being easy to be used can be realized by setting the interval of retaining pieces 2 at a post-card size beforehand.
