<P>PROBLEM TO BE SOLVED: To solve the problem with a conventional configuration for moving an engraving unit in a Y-axis direction having a system of rocking the engraving unit relative to the guide rail, wherein a depth of an engraved hole formed by the engraving unit decreases and a shape of the engraved hole changes from a true circle to an ellipse toward increase in a rocking angle, thereby a depth and a shape of an engraved hole become unstable and it becomes difficult to make good-looking letters and symbols. <P>SOLUTION: An engraving device includes: a base 6 which moves in the X-axis direction; a slide member 13 which moves in the Y-axis direction relative to the base; and an engraving unit 3 attached to the slide member. With this configuration, engraving is performed by a constant engraving force while movement of the engraving unit in the Y-axis direction is horizontally carried out. Accordingly, an engraving pin 3g vertically works on an object to be engraved in all positions and it is possible to constantly engrave true holes. <P>COPYRIGHT: (C)2012,JPO&INPIT |
