<p>PURPOSE:To perform a deciphering process fast by reading the two-dimensional code symbol mark through a code reader by using small storage capacity. CONSTITUTION:The code reader 3 reads the X-axial side display line 4 or/and Y-axial side display line 5 of an information area 8 where the code symbol mark 2 is recorded and detects a section mark 7 recorded on the X-axial side display line 4 or/and Y-axial side display line 5. At each intervals obtained by dividing the distance between the Y axial or/and X-axial section marks 7 by a specific integer, the code mark 9 of a binary signal recorded in the information area 8 is read by the code reader 3 in order up to the end part of the Y-axial side display line 5 or/and X-axial side display line 4 and the code mark 9 recorded in an area formed of each quadrilateral whose one side has length obtained by dividing the interval of the section mark 7 read by the code reader or the distance of the section marks by an integer is processed to decode the code symbol mark 2.</p> |
