<p>PROBLEM TO BE SOLVED: To provide a lumber working system capable of accurately reading a code attached to lumber. SOLUTION: A QR code attached to the upper face of a pillar material W is read, and a working unit works the material W. For this reason, working can automatically be performed simply by attaching a QR code seal 68 to the material W without inputting the data of the material W to a computer. Since the seal 68 is attached to the upper face of the material W here, the QR code seal is prevented from being rubbed when carried, and information can accurately be read from the seal.</p> |
