Abstract

PURPOSE: To achieve the volume production of reflection type hologram media such as of confidential numbers utilized for personal checking by sealing transmission type small hologram pieces together with a thin reflecting piece in a substrate.
CONSTITUTION: Transparent acrylic resin made small hologram pieces 1 having been transferred with minute undulation patterns H of holograms corresponding to numbers of 0 up to 9 are made by injection molds. When the numbers corresponding to the pattenrs H are also simultaneously formed 3, the identification of the patterns H is easy. A reflecting thin plate 6 is sunk into the recess 4 of an acrylic resin made hologram substrate 5, after which the small pieces 1 removed of number forming portions 3 are inserted and temporally fixed for each digit in the windows 7 of an acrylic resin made holding frame 8 in such a manner that the patterns H come below. The step parts 9 of the small pieces 1 engate to the step parts 10 of the windows 7, whereby the small pieces 1 are correctly positioned. Next, this frame 8 is fitted in the recess 4 and the circumference is fixed by adhesive agents 11.
