<p>A two-dimensional code (3) consists of a first figure including line segments (LS11-LS14, LS31-LS34, LS51-LS54, LS71-LS74) arranged at pitches corresponding to a small region size around a data block (2) and index lines (R21-R24, R41-R44, R61-R64, R81-R84) orthogonally extending from substantially the center of each segment and an L-shaped second figure (LC) having ends continuous with ends of the segments (LS54 and LS74). The index lines (R21-R24, R41-R44) are arranged to face the outside of the data block (2) while the index lines (R61-R64, R81-R84) are arranged to face the data block (2). In accordance with these index lines, data density information and positioning information are fetched during decoding.</p> |
