Abstract
A laser beam 7 from an engravement portion softening mechanism 6 of an apparatus is condensed onto an engravement portion on an engravement surface of a workpiece 1 for softening the engravement portion. When the hardness of the engravement portion is lowered, a pen tip 2 of the apparatus is applied to the engravement portion. Thus, it is possible to reduce reliably wear and damage of the pen tip 2 which results from engraving a hard workpiece, and to prolong the useful life of the pen tip 2, so that the durability and the reliability of the apparatus are improved.
