POSITION CORRECTION APPARATUS FOR LASER MARKER

摘要

A low-cost high-speed apparatus for correcting the marking position of a laser marker, which uses a smaller quantity of corrective data and a simplified arithmetic operations, wherein corrective values for design parameters for a lens are obtained on the basis of a production tolerance of the lens. The design parameters of the lens are corrected according to the corrective values, and the distance for the lens to move is calculated from the corrected design parameters of the lens and the distance to a desired marking position. A move command corresponding to the calculated distance is outputted to lens drive means, and a pattern of a divided image is marked in the desired position.
