摘要： A two-dimensional code having a rectangular region is provided. In the rectangular region, there are code blocks composed of a plurality of cells, a first specific pattern specifying the positions of the cells, and a second specific pattern separating the code blocks from a background of the code. The first specific pattern is located at a specified corner of the rectangular region. The second specific pattern is located along one or more of first borders along which the first specific pattern is located, the first borders being part of the borders of the rectangular region. The code blocks include error-correction code blocks, which are located along second borders which are different from a border of the borders along which the second specific pattern is located. The second borders are part of the borders. Compressed data code blocks are also arranged in the same way as the error-correction code blocks.

摘要： A system (1) reads an information code (C) formed on a medium (10). The code has light modules and dark modules. The areas of the light modules are produced as inversion areas inverted light reflection characteristics. The areas of the dark module areas are produced as non-inversion areas non-inverting light reflection characteristics. A reader (40) emits illumination light of wavelengths including infrared light wavelengths to the code (10), and images the code (10) under the illumining light emission. The inversion areas, that is, the light module areas, can be dark under the visible light, but can be a light color due to its inverted light reflection characteristics. The light modules can thus be imaged by the reader (40) under the illumining light emission, providing distinguishable detection of the inversion and non-inversion areas, allowing the light and dark modules to be extracted for decoding.

摘要翻译： 系统（1）读取形成在介质（10）上的信息码（C）。 该代码具有灯模块和暗模块。 光模块的面积是反转区反转光反射特性。 暗模块区域的区域产生非反转区域的非反相光反射特性。 读取器（40）向码（10）发射包括红外光波长的波长的照明光，并且在发光的光发射下对代码（10）进行成像。 反转区域，即光模块区域，在可见光下可能是暗的，但由于其反射的光反射特性，可以是浅色。 因此，可以通过在发光的发光下的读取器（40）对光模块进行成像，从而提供反转和非反转区域的可区分的检测，从而允许提取亮和暗模块以进行解码。

摘要： A two-dimensional code having a rectangular region is provided. In the rectangular region, there are a plurality of code blocks, a first specific pattern, and error-correction code blocks. Each code block is composed of a plurality of cells aggregated together and formed to have both a specified corner in the rectangular region and the plurality of code blocks arranged in the rectangular region. The specific pattern is used to specify the positions of the cells. The error-correction code blocks are contained in the code blocks and formed to correct an error. The error -correction code blocks are arranged contiguously to part of the borders of the rectangular region. The part of the borders is displaced from the first specific pattern. Compressed data code blocks are also arranged in the same way as the error-correction code blocks.

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.
