PURPOSE:To sandwich paper, a photograph, etc. and to enable the exact positioning of a cover for sandwiching the same, by sticking a magnetic stripe on the surface on the side where one protective piece is tightly adhered, penetrating and opening a window of roughly the same shape as the shape of the magnetic stripe in the position where the other protective piece is adhered and exposing the surface of the magnetic stripe from the other protective piece. CONSTITUTION:A slender beltlike magnetic stripe 22 is adhered by means of an adhesive agent or the like on the surface of a base plate 21 which is formed of a plastic or the like and has a square shape of a thin-walled plate along the long side thereon, and both ends of the stripe 22 are spaced slightly from the short side of the plate 21. A protective cover 23 is formed roughly to the same size as the size of the plate 21, and a slender window 24 is opened on the one side along the long side thereof. The window 24 is formed to the opening section slightly larger than the shape of the stripe 22. Paper 25 for a member's certificate which has the shape slightly smaller than the plate 21 and carries a photograph and necessary data is adhered tightly on the surface of the plate 21, and the cover 23 is adhered tightly to the plate 21 from the top surface thereof, whereby the three-layered sandwich structure is obtd. |
