Abstract
An information code includes an information recording area and a state reference area. The information code is generated by combining two pre-combination codes, each of which records information by an array of light cells and dark cells. The information recording area includes multiple types of composite cells, which have different states from the light cells and the dark cells. Information of each of the two pre-combination codes is recorded in the information recording area by the multiple types of the composite cells. The state reference area is arranged in at least one defined pattern, which has a shape defined in advance and is used for reading the information recording area and indicating respective states of the composite cells. In the at least one defined pattern, cells indicating the states of the multiple types of the composite cells included in the information recording area are arranged in consecutive manner.
