A plurality of lattice dots are disposed in a rectangular shape and set as a block, and they are regularly and continuously disposed, and a dot that forms one of the lattice dots which exists in the block is disposed by being shifted unidirectionally and is set as a key dot, and by setting the key dot as a representative point, a plurality of information dots are disposed, and by setting a center which was surrounded by the lattice dots of four points as a hypothetical point, and by setting this as a start point of a vector, at an end point of which, a plurality of information dots which have various information are arranged in accordance with a predetermined rule by a dot code generation algorithm to thereby generate a dot pattern. |
