发明名称 Information code and information code reader
摘要 Disclosed herein are an information code (10) and an information code reader. In the information code, a plurality of light-colored modules exhibiting the reflective characteristics of light color when light of a second wavelength band different from light of a first wavelength band is radiated and a plurality of dark-colored modules exhibiting the reflective characteristics of dark color when the light of a second wavelength band is radiated are arranged in a code region (20). The information code includes a masked portion (11) disposed in a predetermined region of the code region in which light is intercepted and prevents the corresponding information code from being read, and configured to, when the light of a second wavelength band is radiated, allow light reflected from the modules of the corresponding code region to pass therethrough and to interrupt the light of a first wavelength band.
