ることが可能であった。<Embodiment 2> As shown in FIG. 3 (a), an image pattern (31a) of "A" and two image patterns (32a, 33a) symmetrical with respect to two center lines on a rectangular securities.
When an image pattern (34a) that is point-symmetric to the center point (O), which is the intersection of the two center lines, is formed as an infrared transmitting pattern portion, a plurality of securities, front and back, top, bottom, left, and right are overlaid in any order. However, the fake produced in Example 1 could be detected.

られていても偽物を検出することができる。As described above, the present invention has the following effects. That is, a machine-readable infrared transmission pattern that is visually indistinguishable but mechanically readable is produced on the securities, and the transmitted infrared light is used for verification. Therefore, even if a plurality of securities are stacked, a fake is detected. be able to. The printing which cannot be visually identified cannot be distinguished and reproduced by the color copying machine. Further, by printing such that the infrared transmission pattern portion is as shown in FIG. 3, it is possible to detect a fake even when a plurality of securities are arbitrarily arranged on the front, back, top and bottom.
