PURPOSE:To make marking in a correct position and to prevent the degradation in marking quality by correcting a positioned work piece to a marking position by a correcting means when the work piece is deviated in position. CONSTITUTION:A difference is eventually generated in the deviation between the central point position of the work piece 12 detected by position detecting means 19, 20 and a preset central point position for processing when the central point position of the positioned work piece 12 deviates from the preset central point position for processing. Then, the correcting means 18 corrects the position where the work piece 12 is marked in accordance with the result of the computation of the deviation of the work piece 12. The marking on the work piece 12 is, therefore, executed in the correct position. |
